Value in health care is the measured
improvement in a patient’s health
outcomes for the cost of achieving that
improvement.1 The goal of value-based
care transformation is to enable the
health care system to create more value
for patients. Because value is created only
when a person’s health outcomes improve,
descriptions of value-based health care that
focus on cost reduction are incomplete.
Reducing costs is important but not
sufficient: If the real goal of value-based
health care were cost reduction, pain killers
and compassion would be sufficient.

Value-based health care is often
conflated with quality, a vague concept

that implies myriad virtues and in
health care often focuses on inputs
and process compliance. Quality
improvement efforts may not improve
patients’ health outcomes, however;
even given similar processes, different
teams’ results vary. In addition,
requirements to track and report
process compliance may distract
caregivers from the more significant
goal of improving health outcomes.
Diabetes care in Italy provides one
example of process compliance not
ensuring better outcomes: Analysis
of regional variations in process
compliance and in outcome indicators
showed better process compliance in the
north but better outcomes for patients
in the south.2

Certainly clinicians should practice with
the consistency demanded by scientific
methods and follow evidence-based care
guidelines. But results matter. The goal
of value-based health care is better health
outcomes.

Value and patient satisfaction are also
commonly confused. While the patient
satisfaction movement has brought a
much-needed emphasis on treating
people with dignity and respect, the
essential purpose of health care is
improving health. Value is about helping
patients. Satisfaction surveys ask
patients, “How were we?” Value-based
care providers ask, “How are you?”

Why Improving Value Matters

Improving a patient’s health outcomes
relative to the cost of care is an aspiration
embraced by stakeholders across the
health care system, including patients,
providers, health plans, employers, and
government organizations. Value-based
health care aligns these diverse parties’
goals so well that, shortly after the
concept was introduced in 2006, health
economist Uwe Reinhardt described it
as “a utopian vision.”3 While Reinhardt
expressed concern about the challenges
of moving to a value-based system,
he lauded the larger objectives of the
transformation.

By focusing on the outcomes that matter
most to patients, value aligns care with
how patients experience their health.
In this context, health outcomes can be
described in terms of capability, comfort,
and calm.4 Capability is the ability of
patients to do the things that define
them as individuals and enable them to
be themselves. It is often tracked with
functional measures. Comfort is relief
from physical and emotional suffering.
In addition to reducing pain, improving
patients’ comfort requires addressing
the distress and anxiety that frequently
accompany or exacerbate illness. Calm is
the ability to live normally while getting
care. It encompasses freedom from the
chaos that patients often experience in
the health care delivery system, and it

Abstract

Value in health care is the measured
improvement in a person’s health
outcomes for the cost of achieving
that improvement. While some
descriptions conflate value-based
health care and cost reduction, quality
improvement, or patient satisfaction,
those efforts—while important—are
not the same as value, which focuses
primarily on improving patient health
outcomes. A decade of research into
organizations that have achieved better
outcomes while often lowering costs
suggests a strategic framework for

value-based health care implementation
that starts with identifying and
understanding a segment of patients
whose health and related circumstances
create a consistent set of needs. An
interdisciplinary team of caregivers
then comes together to design and
deliver comprehensive solutions
to address those needs. The team
measures the health outcomes and
costs of its care for each patient and
uses that information to drive ongoing
improvements. Care provided in this
way aligns delivery with how patients

experience their health and reconnects
clinicians to their purpose as healers. It
also asks physicians to think differently
about their role within the larger care
team and about the services that team
provides. The authors suggest medical
schools should incorporate education
on the principles and implementation
of value-based health care throughout
the undergraduate medical curriculum
to prepare their graduates to lead
the transformation to value-based
health care as they enter the physician
workforce.

is especially important for people with
chronic and long-term conditions. Care
that improves outcomes in all 3 of these
dimensions creates a better experience for
patients. Moreover, capability, comfort,
and calm describe outcomes that result
from the efficacy and empathy of health
care, rather than its hospitality.

Value-based health care connects
clinicians to their purpose as healers,
supports their professionalism, and
can be a powerful mechanism to
counter clinician burnout. Critics who
characterize value-based health care as
underpinning a model of “industrial
health care”5 distort the meaning of the
term value, misinterpreting it as focused
on cost. Instead, value-based health
care’s focus on better health outcomes
aligns clinicians with their patients. That
alignment is the essence of empathy.
Measured health outcomes demonstrate
clinicians’ ability to achieve results
with patients and families and drive
improvement in the results that matter
most to both patients and clinicians. This
intrinsic motivation is often missing in
the health care system, where clinicians
are directed to spend countless hours on
tasks that do not impact their patients’
health.

Better outcomes also reduce spending
and decrease the need for ongoing care.
By improving patients’ health outcomes,
value-based health care reduces the
compounding complexity and disease
progression that drive the need for more
care. A patient whose diabetes does not
progress to kidney failure, blindness, and
neuropathy is, over time, dramatically less
expensive to care for than a patient whose
condition continually worsens.6

Value-based health care is a path to
achieving the aspirational goals of the
Institute for Healthcare Improvement’s
“triple aim”—improving the patient
experience of care, improving the health
of populations, and reducing the per
capita cost of health care—as well as
improving clinician experience, a fourth
aim that others have proposed.7,8 Patient
and clinician experience improvements
are described above. Population health
only improves when the health outcomes
of many individuals improve, which is the
focus of value-based health care. Costs
also cumulate from the care provided
for individuals. By organizing teams to
care for individuals with similar needs, a

value-based approach enables expertise
and efficiency, rather than rationing, to
drive costs down. This puts decisions
about how to deliver care in the hands
of the clinical team, rather than those of
an insurance administrator, supporting
the professionalism of clinicians and the
power of clinician–patient relationships
to deliver effective and appropriate care.

A Framework for Implementing
Value-Based Health Care

Improving value in health care is
not an unreachable utopian ideal.
Around the globe, health care delivery
organizations—in varied payment
settings, with an array of regulatory
structures and many different care
traditions—have demonstrated
dramatically better health outcomes
for patients, usually at lower overall
costs.1,4,9,10 More than a decade’s research
into these organizations by 2 of the
authors (E.T. and S.W.) elucidates a
clear framework for value-based care
transformation.11

That framework, shown in Figure 1
and described below, can guide
organizations in building value-based
health care systems. This transformation
starts when the organization identifies
and understands a segment of
patients whose health and related
circumstances create a consistent set
of needs. A dedicated, co-located,
multidisciplinary team of caregivers
designs and delivers a comprehensive
solution to those needs. This integrated
team measures meaningful health
outcomes of its care for each patient
and the costs of its services and then
learns from that information to drive
ongoing improvements in care and
efficiency. Finally, as health outcomes

improve, evidence of better care creates
opportunities for the team to serve more
patients through expanded partnerships.

Understand shared health needs of
patients

Throughout the economy, service
providers organize their offerings around
a defined set of customers whose needs
are similar. Think, for example, of
transportation providers. Transportation
is an incredibly broad economic sector.
Services range from jets that deliver tons
of time-sensitive cargo to drones that
deliver individual bags of blood, and
from buses to rented electric scooters. In
each case, the transportation company
matches its services to the needs of its
customer segment.

Health care is the outlier. In the
health care system, most services are
organized around the service providers.
Endocrinologists practice in groups
with other endocrinologists, as do
cardiologists, ophthalmologists, and
podiatrists. A patient with diabetes, who
likely needs the coordinated—or, even
better, integrated—services of these
various clinicians, has to be the organizer.
Health care’s general failure to structure
around patient needs accounts for its
inconvenience and lack of integrated
services. Failing to structure for what is
common and routine also increases the
burden on caregivers, who too often must
improvise to solve routine problems. This
structural mismatch is a root cause of
why health care is so expensive and does
not deliver better results for patients.1

To be effective and efficient, health care
should be organized around segments
of patients with a shared set of health
needs, such as “people with knee pain”
or “elderly people with multiple chronic

Figure 1 Strategic framework for value-based health care implementation to achieve better
patient outcomes.

conditions.” Organizing care in this
way allows clinical teams to anticipate
consistent patient needs and provide
frequently needed services efficiently,
doing common things well. The efficiency
afforded by structuring care around
patient segments frees clinicians from
scrambling to coordinate services that are
needed routinely. The added bandwidth
allows them to personalize services
for individual patients who may have
somewhat different needs.

Design a comprehensive solution to
improve health outcomes

Starting by identifying the common
needs of a patient segment enables teams
to design and deliver care that provides
a comprehensive solution for patients
or families. When the goal of care shifts
from treating to solving patients’ needs,
care teams can both address the clinical
needs of patients and begin to address
the nonclinical needs that, when left
unmet, undermine patients’ health.
For example, a clinic for patients with
migraine headaches might provide not
only drug therapy but also psychological
counseling, physical therapy, and
relaxation training. Similarly, a clinic
for patients with cancer might include
transportation assistance as a service for
those who have difficulty getting to their
regular chemotherapy appointments.
Broadening and integrating the services
provided to patients achieves better
outcomes by identifying and addressing
gaps or obstacles that undermine
patients’ health results.4

Integrate learning teams

Implementing multifaceted solutions
requires a dedicated team drawn from
an array of disciplines, many of which
are not typically viewed as medical.
An effective team integrates services,
reducing or even eliminating the need for
coordinators. Team members are often
co-located, enabling frequent informal
communication that supplements the
formal channels of communication to
ensure effective and efficient care. What
is critical is thinking together to improve
and personalize care and learning
together so health outcomes improve
with experience. The team structure can
also expand across locations, extending
state-of-the-art knowledge to remote
clinicians and enabling world-class
care to be delivered locally rather than
requiring patients to travel.

Measure health outcomes and costs

It is a truism of business that
management requires measurement.
Recognizing that the essential purpose
of health care is improving the health of
patients, it is axiomatic that health care
teams must measure the health results
as well as the costs of delivering care
for each patient. Leaders cannot align
health care organizations with their
purpose without measurement of health
outcomes. In addition, the current dearth
of accurate health outcomes and cost data
impedes innovation.

Measurement of results allows teams to
know they are succeeding. Measuring
health outcomes also provides the data
needed to improve care and efficiency.
Although caregivers are burdened with
reporting reams of information, they
rarely consistently track the health
outcomes that matter most to patients
and thus to themselves as clinicians. Cost
and health outcomes data also enable
condition-based bundled payment
models, empowering teams of caregivers
to reclaim professional autonomy and
practice clinical judgment—two integral
elements of professional satisfaction and
powerful antidotes to the affliction of
burnout.1,12–14

Measuring health outcomes is not as
complex as it is often perceived to be.
Routine clinical practice does not dictate,
nor can it support, the voluminous health
outcome measure sets used in clinical
research. Instead, clinicians need to focus
on measuring the outcomes that define
health for their patients. Those outcomes
cluster by patient segment—the
outcomes that matter most to patients
with congestive heart failure are strikingly
consistent while also markedly different
from the outcomes that matter most to
women who are pregnant. Within any
given patient segment, though, patients
define health in terms of capability,
comfort, and calm, as described above,
and these dimensions can be usually
captured in 3 to 5 measures. For
example, men undergoing prostate
cancer surgery are most concerned about
the common impairments from that
procedure—incontinence, impotence,
and depression—as well as time away
from work for recovery.

In addition to health outcomes, teams
must measure the costs of their services

for every patient. Cost-grouping
methodologies like the one developed at
the University of Utah15 or applications
of time-driven activity-based costing16
can provide the data teams need both
to demonstrate the value of their care
and to identify areas for improving their
efficiency.

Expand partnerships

Organizing around patients with shared
needs and demonstrating better value
in care create opportunities to expand
partnerships and improve health
outcomes for more people. For example,
with evidence of care that has fewer
complications and allows employees to
return to work more quickly, employers
are increasingly willing to contract
directly with providers and even to
pay more per episode of care than
they had previously, because faster and
fuller recovery reduces other employer
costs such as those associated with
absenteeism.17 Partnerships among
clinical organizations may also expand
as teams gain expertise and the ability
to work across more stages of the care
cycle or more locations. Integrated teams
may work with partners for an array of
reasons, such as using new technology
to share information with patients,
supporting rural clinicians as they
provide patients with care close to home,
or offering services to support lifestyle
changes in a community. These are
natural partnerships because the shared
goals of creating high value and achieving
better health outcomes for patients align
the interests of patients, family members,
employers, health plans, and clinicians,
as well as medical technology suppliers
whose services may facilitate these
relationships.

Value-Based Health Care in
Medical Education

Moving to a system of value-based
health care requires that physicians and
physicians-in-training learn to think
differently about their role within the
larger care team, about what constitutes
an effective care solution, and about
the importance of measuring the health
outcomes that matter most to patients.
That learning should begin during
medical school.

The University of Texas at Austin’s Dell
Medical School (DMS) offers an example

Invited Commentary

Academic Medicine, Vol. 95, No. 5 / May 2020 685

of how education about value-based
health care can be incorporated into
undergraduate medical education.
Throughout the 4 years of medical
school, DMS students study the
principles of value-based care delivery
described above. During their clinical
rotations, they also see these principles in
practice in UT Health Austin’s affiliated
clinics, which are organized around
segments of patients with shared needs
and designed to provide comprehensive
solutions delivered by interdisciplinary,
outcomes-focused teams.

In the joint pain clinic, for instance,
DMS students observe interdisciplinary
care teams providing comprehensive
care to alleviate pain and improve
functioning. Treatment may entail joint
replacement surgery, but surgery is used
less frequently than in other orthopedic
care settings. Those who are not seen
as good candidates for surgery might
instead receive physical therapy, care
for depression or other mental health
conditions, and/or weight loss support.
The clinic tracks health outcomes for all
patients and has found that while the
rate of patients receiving lower extremity
surgery is 30% lower than that of patients
in conventional care settings, more
than 60% of patients report significant
reductions in pain and improvements
in function 6 months after the initial
appointment.18

DMS’ curriculum also allows third-
year medical students (and other
interested health professionals) to
complete a master’s degree in health care
transformation, focused on the principles
and implementation of value-based
health care. We encourage other medical
schools to incorporate similar training

throughout their curricula to prepare
their graduates to lead the transformation
to value-based health care as they enter
the physician workforce.

INTRODUCTION

Current trends in global health care systems

Globally, health systems face immense challenges due to growing demand for
healthcare services, rising costs and increasingly higher complexity of illnesses
and the solutions to address them. Despite higher expenditures in health systems,
health outcomes have not improved proportionately. From 2014 to 2040, the world’s
spend on health care will increase almost three-fold to reach approximately USD 25
trillion per year. This increase in spending is primarily driven by population ageing,
increase in chronic diseases, inefficiency and ineffectiveness of the current health
system models and rising costs f rom f new technologies. In most Organisation for
Economic Co-operation and Development (OECD) countries, health care spending
is increasing faster than economic growth and driven by ageing and excess cost
growth due to chronic illness and health system inefficiency.

The combined challenges of rising demand and growing healthcare expenditures
that exceed the rate of economic growth pose a real and substantial risk to
sustainability of health systems and their ability to provide better access to safe,
high quality health care to all citizens of the G20 member countries and beyond.
The conference participants recognized the critical importance of VBHC as an
instrumental part of achieving sustainable Universal Health Coverage (UHC) – a
target for the United Nations Sustainable Development Goal (SDG) 3 ‘Ensure healthy
lives and promote well-being for all at all ages’.

Accelerating the introduction and scale-up of VBHC to address pressing threats to
health systems

“Health systems are
organized to manage
acute events with single/
short interventions and
need moving towards
medium long term
health caring”

Dr. Giuseppe Ruocco,
Ministry of Health, Italy

Health systems need to transition to
VBHC models that achieve a better
balance of outcomes and resources used,
if the current threats are to be effectively
managed.

Traditional health care models use
payment models, such as ‘fee for service’
and ‘activity-based payment’, primarily
focus on paying for inputs and the volume
of services provided. These payment
models reward ever-increasing volumes
of activities and services, but without the
commensurate improvement in health
outcomes and outcomes that matter
to patients. By contrast, VBHC offers a
model that puts increasing value for

6www.g20.org |Accelerating Transformation Towards Sustainable Health Systems Through Value Based Health Care

patients first. This includes increased accessibility and affordability of health care for
patients. From the pharmaceutical industry perspective, Mr. Sinan Atlig f rom Pfizer,
the Regional President Biopharma MEA, agreed that health care costs and overall
spending on medicines need to be kept in check to create a more sustainable health
system.

Furthermore, many panelists emphasized the importance of defining health care
broadly to include maintenance or improvement of health through promotion of
good health, and through prevention, diagnosis and treatment of illness, injury,
disease, and other physical or mental impairments.

The CEO of the Center for Improving Value in Health, Dr. Reem AlBunyan highlighted
in her opening remarks, that value in health care means better health and better
care at lower cost, with a focus on the person. Ms. Herta Adams, the Deputy Head
of Health Determinants and International Relations at the European Commission
proposed a similarly broad definition of value in the context of VBHC, based on four
pillars:

Personal value, accomplishing the personal goals of patients
Technical value, achieving highest outcome quality with limited resources
Population value, equitably delivering care and allocating resources to
patient populations
Societal value, fostering societal participation by delivering health care

The report consists of two sections that explore: (1) how VBHC can be realized through
common key enablers in diverse settings and (2) how collaborations and knowledge
transfer between organizations and countries help spread and establish successful
VBHC models.

“VBHC means placing
patients – both their
experience and
outcomes – at the heart
of decision-making”

Ms. Herta Adam,
European Commission

SUMMARY OF KEY FINDINGS

1. VBHC can be realized through common enablers in diverse settings

The first section of this report explores learnings f rom various sessions revolving
around the necessary building blocks and levers to set up VBHC models. Case
studies illustrate key learnings and best practices on VBHC approaches.

A. VBHC approaches introduce innovative solutions to transform health
systems to achieve greater value and sustainability

According to Prof. Rifat Atun, Professor of Global Health Systems at Harvard University,
current health systems are under pressure because of a coalescence of several
fundamental contextual drivers that pose threats, including rapid population ageing,
rising burden of chronic illnesses, higher patient expectations, fiscal constraints on
governments due to economic downturns. This is against a backdrop of an ever-
increasing innovation in new health technologies, diagnostics and medicines which
are not optimally harnessed to improve system performance.

Worldwide, health systems are struggling to achieve desired levels of effectiveness,
efficiency, equity and responsiveness that meet user expectations. This is because
health systems are failing to innovate because of:

(i) Innovation misalignment: There is robust ‘delivery of innovations’, such as
new diagnostics, health technologies and medicines, but there is
a failure in the ‘innovation in delivery’, with few fundamental
improvements in healthcare service delivery models which remain archaic.
(ii) Policy misalignment: Innovation is encouraged for by industrial policies but
their adoption and scale-up is constrained by health policies

8www.g20.org |Accelerating Transformation Towards Sustainable Health Systems Through Value Based Health Care

In his presentation, Prof. Atun explained
how health systems have historically
transitioned f rom one model to another
over time: f rom a model with structural
focus, where payments followed
inf rastructures (e.g. hospitals), to a more
functional focus, in which payments
follow activities. However, we are currently
observing a new fundamental shift
towards value, and the many practical
examples shared during the event are
the best examples of this trend. In this
model, payments follow value, with
better health outcomes for individuals
or populations, as exemplified by VBHC
approaches.

“There is no shortage
of innovation, but they
are in pockets. We need
to scale innovation to
create impact”

Ms. Herta Adam,
European Commission

“Everything is new, and
we do not have off-the-
shelf solutions. There
is no such thing as
failure, it is a learning
experience”

Prof. Rifat Atun,
Harvard University

According to Prof. Atun, VBHC is underpinned by four major principles: transparency,
optimization of cost and outcomes, shared accountability, and shared risk and reward.
In practice VBHC models include several core critical components. The first of these
is ‘digital data systems’ and analytic capability that enable pooling and application
of data to measure costs, processes and outcomes. The second is ‘stratification’ or
‘categorization’ of population groups according to their characteristics to ensure
better understanding of needs and the development of targeted solutions. The third
is ‘risk-adjusted bundled care’, which brings together a targeted set of interventions
across the care continuum for populations with different levels of risk of illness.

The fourth component is the ‘integrated care’ across the care continuum, enabled by
‘integrated care pathways’ and integrated provider networks that ensure seamless
care. An integrated care pathway ideally contains the entire patient journey for a
specific disease, f rom prevention, detection, treatment, monitoring to rehabilitation
(Figure 2). The fifth component is
‘outcome based payment models’
that incentivize achievement of better
outcomes and lowering of costs. The sixth
and often overlooked crucial component
is ‘behavior change’ in policymakers,
payers, healthcare providers and health
service users that creates a conducive
environment to challenge the status quo
and encourage the development and
scale-up of VBHC solutions to address the
current weaknesses in health systems.

Figure 2: Integrated Care Pathways

Legacy Focus

VBHC Focus

Digital systems are a critical ingredient that connects these components to enable
the development of person centered integrated care delivery models aimed at
achieving better patient reported outcomes and creation of greater value, as
illustrated by case study [1]: DigiPROM at Charite Berlin.

Case study [1]: DigiPROM at Charite Berlin

Situation: The Federal Ministry of Health, Germany wanted to study the feasibility
of patient-reported outcome measures (PROMs) in German hospitals.
Ambition: Testing digitalized PROMs for back pain-related interventions and
exploring DigiPROM as a concept for standardization across Germany. Additionally,
this pilot tests the technical feasibility to combine clinical data with PROMs.
Outcome: Patients benefited f rom improved treatment due to quality transparency
and improvement.

Case study [2]: Ayushman Bharat

Situation: The Indian government strives towards UHC for its population to address
urging issues such as the increasing burden of non-communicable diseases and
rising healthcare costs.

Ambition: In 2017, the Ayushman Bharat program was launched. This program
rests on two main pillars, AB-HWCs and PMJAY. AB-HWCs, Ayushman Bharat
Health and Wellness Centers, provide primary care to all citizens for an initially
limited selection of health services. PMJAY, Pradhan Mantri Jan Arogya Yojana,
aims to prevent excessive health expenditures for the 40% poorest for secondary
and tertiary health care services.

Outcome: To date, 27,923 AB-HWCs have been transformed across the country and
provided treatment to 11.3m. people for hypertension, 5.7m. for diabetes and 9.2m.
women screened for breast cancer. To date, approx. 20,000 hospitals participate in
PMJAY and 7.5m. patients were treated under this cover worth USD 1.8 bn.

10www.g20.org |Accelerating Transformation Towards Sustainable Health Systems Through Value Based Health Care

With a focus on outcomes, VBHC considers the whole
patient journey, including disease prevention and
monitoring of health. This contrasts with legacy systems
that mainly focus on diagnosis and treatments, driven
by their focus on reimbursement by activity (e.g. fee-for-
service, and activity-based payment models)

Focusing the care pathways only on the direct delivery of clinical care would be too
narrow an approach in achieving value. Around 80% of the factors that determine
health outcomes lie not within healthcare services but include social-determinants
of health, as Mr. Lav Agarwal, the Joint Secretary, Indian Ministry of Health & Family
Welfare, points out. These factors include nutrition, sanitation and water access, air
pollution, physical activity, and among others consumption of alcohol and tobacco.
That is why the Indian government has acted and initiated programs aimed at
educating its population and promoting healthier lifestyles. Such programs include
“Fit India Movement” and “Eat Right India.” Those programs are part of a larger
national initiative, Ayushman Bharat: “Bless India with long healthy life” in Hindi,
which aims to provide UHC in primary care, based on VBHC principles (case study
[2]: Ayushman Bharat).

The delegation f rom Australia shared a case study f rom their recent reforms on
activity-based funding (ABF) that aimed to achieve the following:

Improving access to services for patients
Increasing the efficiency of public hospitals
Improving the transparency and sustainability of public hospital funding
The development and implementation of funding and pricing approaches
for safety and quality.

As part of these reforms, the Independent Hospital Pricing Authority (IHPA) was
established to determine the National Efficient Price, and set up the underlying
inf rastructure to support ABF, such as classifications, data specifications, costing
and pricing. (Case study [3]: Pricing Framework for Australian Public Hospitals)
IHPA’s decisions on these matters were detailed in the Pricing Framework for
Australian Public Hospital Services 2017-18:

1. No funding for a public hospital episode including a sentinel event, applying
to all relevant episodes of care in all hospitals
2. Reduced funding level for all Hospital Acquired Complications, to reflect the
additional cost of a hospital admission with a hospital acquired complication
3. Undertake further public consultation to inform a future pricing and funding
approach in relation to avoidable hospital readmissions, based on a set of
definitions to be developed by the Australian Commission on Safety and
Quality in Health Care.

11www.g20.org |Accelerating Transformation Towards Sustainable Health Systems Through Value Based Health Care

Case study [3]: Pricing Framework for Australian Public Hospitals

Ambition: to improve Australians’ health outcomes and decrease avoidable
demand for public hospital services.
Outcome: Whilst this reform is still in the early stages of implementation, there
is evidence that clinicians and hospital managers are using the pricing signal to
undertake significant work to improve the rate of occurrence of HACs across the
system.

B. An enabler for the successful delivery of VBHC is the ability to identify and
measure outcomes that matter most to individuals

During the event Ms. Francesca Colombo, Head of the OECD’s Health Division,
highlighted two noteworthy numbers: first, the average spending of 36 OECD
member states for health care amounts to around 8.8% of GDP, with the United
States leading the pack with 16.9%; second, some OECD countries (e.g. Switzerland
and Germany), undertake six times more knee replacement operations per 100,000
inhabitants than others (e.g. Poland). This raises the questions of whether this
spending and variance in elective surgery rates are due to over/undertreatment, or
differing health needs in different contexts and if a country is getting value f rom the
spending and health interventions.

Such questions can only be answered by measuring patients’ wellbeing before
and after the treatment. To measure the value of treatments in a comprehensive
and standardized way, the OECD launched the Patient-Reported Indicators
Surveys (PaRIS) initiative. This initiative aims to record and report the outcomes
and experiences of patients undergoing various health treatments. Initial data sets
collected by PaRIS include data regarding hip surgery and cancer, with data points
that include; the extent of pain and when they are mobile after surgery, what health-

“It is not about what is
being done in health
systems, it is about what
health systems deliver to
people and populations
at large”

Ms. Francesca Colombo, OECD

related quality of life do patients have
undergoing cancer therapy and to what
extent do they experience anxiety and
depression.

Ms. Colombo highlighted that when
people are at the center of health care,
we can really measure what matters to
them and therefore bring benefits to
them as well as healthcare providers and
policymakers. For example, healthcare
providers profit f rom a new source of
feedback to improve the quality they

12www.g20.org |Accelerating Transformation Towards Sustainable Health Systems Through Value Based Health Care

provide. On the other hand, policymakers profit f rom focusing their attention on
areas that need legislative improvements to create a favorable environment for the
development of person-centered healthcare delivery models.

The OECD is not alone in investing in programs that record and report the outcomes
and experiences of patients undergoing various health treatments. Many countries
such as Germany and Spain are designing systems for recording and measuring
patient-reported outcomes in pilot projects. For example, Germany has had over
15 years of experience with patient-reported outcomes (Case study [1]: DigiPROM
at Charite Berlin; Case study [4]: Martini Hospital in Hamburg). The collection of
data on patient-reported outcomes has had important implications for the quality
of treatment, as Dr. David Herr f rom the German Ministry of Health explained. The
follow up of clinical outcomes provided valuable feedback to individual surgeons
that actively started to learn f rom each other by sharing best practices. The use of
patient-reported outcomes have enabled similar success in the case of prostate
cancer in Spain (case study [5]: Patient-centric care in Cruces Hospital)

Lastly, to facilitate measurement of outcomes and patient experience, new data tools
and analytic capability are currently being developed, which are discussed later in
this paper.

Case study [4]: Martini Hospital in Hamburg

Situation: The Martini hospital, specialized in high volume radical prostatectomy
introduced patient-reported outcomes collection.
Ambition: Recording systematically the clinical outcome of patients after one
week, six months, and then yearly.
Outcome: Patient-reported outcomes provided valuable feedback to individual
surgeons and allowed best practice sharing, raising the quality of clinical
intervention.

13www.g20.org |Accelerating Transformation Towards Sustainable Health Systems Through Value Based Health Care

Case study [5]: Patient-centric care in Cruces Hospital

Situation: The Cruces Hospital in Spain deploys the guidelines of the International
Consortium for Health Outcomes Measurement (ICHOM) for a selection of
candidate diseases. One of them is prostate cancer.
Ambition: Creating a more patient-centric approach by following the guidelines
f rom ICHOM. These guidelines include the collection of standardized data sets
concerning clinical parameters as well as information reported by patients.
Outcome: In the case of prostate cancer, symptoms such as urinary incontinence
were significantly reduced after treatment, along with decreasing costs. The
initiative is interesting due to the long history of structured recording of the clinical
data and PROMs in the Basque health system.

C. Non-financial incentives and factors impacting the success of VBHC

The panel discussions revealed that money is only one lever in an inventory of
incentives to drive the transformation of health systems towards VBHC. Recalling that
change is driven by people, Dr. Omar Alshanqeety, CEO of the Program for Health
Assurance and Purchasing in Saudi Arabia, illustrated that purpose, fulfillment and
enjoyment are also incentives that people long for in their work. Addressing the
intrinsic motivation of people is key, summarized Dr. Derrick Heng, Group Director
of Public Health f rom the Singaporean Ministry of Health.

Recognition for achievements can also be a powerful incentive: the representative
f rom the Russian Ministry of Health, Prof. Lyalya Gabbasova, Assistant to the Minister
of Health, highlighted that best practice primary care facilities in Russia are awarded
special recognition and status, and to date more than 3,000 facilities have received
this status.

“Finance is necessary,
but not suff icient to
change behavior ”

Dr. Omar Alshanqeety, Program
for Health Assurance and
Purchasing, Saudi Arabia

People need to feel empowered and
enabled by providing them the right
tools. Additionally, health professionals
and patients should be empowered to
take ownership of their decision making.
This links back to motivating people by
allowing them to change the system, as
it was emphasized by Mr. Agarwal f rom
the Indian Ministry of Health & Family
Welfare. He also raised the important
point of educating consumers, not
only current patients, and taking them
along on the journey of health system
transformation.

14www.g20.org |Accelerating Transformation Towards Sustainable Health Systems Through Value Based Health Care

D. VBHC involves development of new data tools and analytic capabilities

Data are available in vast quantities, and this holds true in the context of health care.
However, these data should not only be collected but also connected, as agreed
by virtually all the speakers who were present at the conference. Only by linkage of
available data, can one readily leverage advanced analytics to derive genuine and
novel insights for improving health care. Microsoft’s MEA Regional Industry Lead for
Health and Life Sciences, Mr. Mohammed Saleh identified five major categories of
health data:

Clinical (e.g. electronic medical records [EMRs], images, scans)
Pharma and life sciences (e.g. clinical trials, -omics)
Patient and citizen (e.g. purchasing data)
Claims and cost (e.g. claim requests, prices)
Geo/social/environmental (e.g. social service data)

Most of the data exist for every patient today but the data sources cannot talk to each
other. Today, we have a system of record, e.g. Electronic Medical Records (EMRs),
with little analytics and connections to other data sets. Pushing the connectivity and
exchange of data and adding analytical capabilities, systems of Artificial Intelligence
(AI) can be created. Such systems can cross-analyze large amounts of data in real-time
and perform prescriptive analytics (Case study [6]: Ochsner Health System).

To enable such technologies, it is important to share comprehensive high-quality
data sets among institutes, entities and across borders. In interviews with the
organizers of the event, both the representatives f rom the OECD and the World
Economic Forum (WEF) called for better global convergence and interoperability of
digital systems and outcome measurements.

“It’s not about
integrating data, it’s
about connecting data”

“From a technology
perspective the tools are
there. The open question
is governance, and this is
the big issue nowadays.
Who owns the data?”

Mr. Mohammed Saleh,
Microsoft

“It is not just good
enough to collect data,
there are oceans of data.
We need analytics that
generate intelligence ”

Prof. Rifat Atun,
Harvard University

15www.g20.org |Accelerating Transformation Towards Sustainable Health Systems Through Value Based Health Care

Case study [6]: Ochsner Health System

Situation: Physicians supervise many patients and need to split their time among
those patients. Cardiac arrests in patients can occur and are life-threatening
without warning signs perceivable by treating physicians.
Ambition: Predict cardiac arrest before it happens by reading out vitals every
minute and having them analyzed and processed by machine learning algorithms.
If the software detects suspicious signals it will alert a physician preemptively.
Outcome: During a 90-day pilot, the number of patients suffering a cardiac or
respiratory arrest was reduced by 44%, mortality by cardiac arrest was eliminated
on the floor during the trial.

Mr. Agarwal f rom the Indian Ministry of Health & Family Welfare showcased that
creating a unique medical ID on a robust IT platform is pivotal to ensure interoperability
as:

“What we need to do is
to create a standard for
interoperability that is
applicable in different
realities. It needs to be
focused on outcomes.”

Mr. Lucas Scherdel, WEF

“ There is a strong
impetus to extract more
value f rom our health
care system to ensure
sustainability”

Dr. Derrick Heng,
Ministry of Health, Singapore

It will allow information and
feedback flow across primary,
secondary and tertiary healthcare
by mapping of facilities and
resources at every level of care
It enhances trust and accountabili
ty due to simplicity and ease of use
It allows robust f raud detection
by developing an integrated fraud
and abuse detection system

Dr. Heng f rom the Singaporean
Ministry of Health mentioned that by
collecting and analyzing clinical quality
and cost data, one cannot only identify
opportunities for improvements but also
determine best practices for enhancing
value.
A survey of the event participants revealed
that one third of the respondents thought
co-production of solutions by different
stakeholders the most important
enabler, but 44% thought consulting
widely, challenging existing practice, co-
production of solutions and the creation
of an ecosystem for innovation were all
equally important (Figure 3).

the most important VBHC enabler?

II. Collaborations and knowledge transfer between organizations and countries

This section explores key learnings f rom insightful presentations and panel
discussions on the critical success factors and those hindering the establishment of
VBHC models.

E. VBHC can be applied and have positive impact at different scales

There is no ‘boilerplate’ solution that countries can simply pick up and apply
unchallenged locally. During the meeting a variety of pilots, initiatives and international

“In the past we talked a
lot about VBHC, but we
had no actions. We had
those actions in the last
years”

“When [VBHC] was
def ined it was more a
doctrine, now it is much
more practical because
we are working with
it. We understand now
what we can do with it
and what not”

Mr.Erik Jan Wilhelm, Zilveren
Kruis

collaborations were presented. All the
examples were guided by trust between
the involved parties, transparency and
alignment on collected data, focus
on solutions rather than procedures,
novel reimbursement models, a shift in
mindset of all involved stakeholders, and
patient centricity.

The presence of multiple examples across
different geographical scales provides a
proof-of-concept that VBHC approaches
can be adapted, applied and scaled-up
globally in different realities and scopes.
Panelists at the conference were positive
that the philosophy of VBHC is now
supported by concrete examples f rom
different geographies and sizes.

The acceleration of the introduction and

17www.g20.org |Accelerating Transformation Towards Sustainable Health Systems Through Value Based Health Care

adoption of different VBHC approaches has happened thanks to public and private
initiatives and partnerships at varied scales, such as the partnerships between Roche
and The Capital Region in Denmark or Medtronic with the Lehigh Valley Health
Network. Or partnerships that require government commitment at the region or
country level, such as in Italy and Saudi Arabia, and investments in programs by

“You cannot scale
solutions ‘as is’, each
solution is different”

Mr.Said Haddad, Johnson &
Johnson

large international organizations at the
international scale.
As an example of a countrywide program,
involving many stakeholders, are UK
initiatives with the aim to measure
variability in the delivery of care. As
described by Ms. Rose Willis, Deputy
Head of Provider Efficiency at the UK
Department of Health and Social Care, a
large volume of inefficient spending in the
system can be prevented by measuring
and communicating variability in care
and clinical practice, e.g. in hospitals. The
measures of variability were developed
in collaboration with clinicians to whom
they will apply. £2.9bn has been saved so far by this initiative.

On the interface between the country and international levels, panelists presented
first international collaborations across country borders, for example the collaboration
between a Dutch payer and a clinic in Germany for prostate cancer surgeries (Zilveren
Kruis in the Netherlands and the Martini Clinic in Hamburg), or the innovative shared
value-driven procurement by Catalonia in Spain and in the UK for pacemakers.

18www.g20.org |Accelerating Transformation Towards Sustainable Health Systems Through Value Based Health Care

Figure 4: Some of the initiatives, pilots, and case studies discussed during the G20
side event on VBHC, categorized by geography and type

F. Reciprocity is key to successful collaborations

Successful VBHC pilots which are subsequently extended for broader implementation
require strong ties and goal alignments with collaborators. Collaboration between
patients, physicians, and organizations need to be mutually beneficial to create
strong enough incentives for all concerned to follow through and generate a
necessary level of trust.

To create this trust and special relationship, it is important to ascertain what VBHC
means to each party. VBHC means different things to different people, for example
better outcomes, better efficiencies, or better financials. The knowledge of context
is instrumental to align on what the partners want to achieve by the use of VBHC
approaches.

“Partnership is not a
noun, it is a verb. You
have to work on it”

Prof. Rifat Atun,
Harvard University

Mr. Said Haddad, the VP of Ethicon
EMEA for Johnson & Johnson, called for
a value based model of procurement.
Traditionally, stakeholders oppose each
other when negotiating prices. The
purchaser wants to obtain the lowest
possible price whereas the vendor wants
the opposite. To overcome the fixation
on price as the key decision criteria,
requires a shift in the mindset – moving
away f rom price and towards value.
Interestingly, 70% of procurement in

19www.g20.org |Accelerating Transformation Towards Sustainable Health Systems Through Value Based Health Care

Europe is done through tenders with a major focus on price. In the Middle East, Mr.
Haddad explained, it’s even higher at 80-85%.

Mr. Ramon Maspons, the Chief Innovation Officer f rom the Catalonian Ministry of
Health, shared a similar view. He described the need to transition to value based
procurement as more and more innovations and solutions that incorporate
innovative technologies, devices and medicines developed and more funds are
needed to procure these innovations.

There are 22 value based projects currently operational in Catalonia. In one of
the pilots, the Catalonian Ministry of Health procured an automated implantable
cardioverter defibrillator for Sant Pau hospital (Case study [7]: The Sant Pau case). This
defibrillator allowed remote monitoring and included cardiac re-synchronization,
adding another layer of care for patients. Patient outcome and wellbeing improved,
hospital productivity rose and their overall spending was reduced while the vendor
made money. This was achieved because procurement was not of the product

“We are not buying
products anymore, we
are buying solutions.
Using procurement as a
trigger for change”

Prof. Rifat Atun,
Harvard University

“Never before was there
so much innovation in
the funnel, never before
so little money for
adopting innovation”

Ramon Maspons, Catalonian
Ministry of Health

alone, but an entire solution; the remote
monitoring and maintenance of each
device was done by the manufacturer,
reducing hospital visits by the patients,
and both sides had the common aim of
lowering mortality as an incentive.

20www.g20.org |Accelerating Transformation Towards Sustainable Health Systems Through Value Based Health Care

Case study [7]: The Sant Pau case

Situation: The Catalan Ministry of Health, together with the Hospital de la Santa
Creu I Sant Pau piloted a new approach to treat patients with arrhythmias
(abnormal heartbeats)
Ambition: Comprehensive treatment of patients with automated implantable
cardioverter defibrillator (AICD) including cardiac re-synchronization. This
approach was designed to reduce follow up visits, introduce remote monitoring
of patients, and reduce costs by including health outcomes.
Outcome: Quality of life for patients improved drastically. There was a reduction
in in-office visits by ca. 10% and reduction of inappropriate shocks per patient by
ca. 66%.

Mr. Lars Dahl Allerup, New Business Development Manager f rom The Capital Region
of Denmark, concurred that price should not be the most important criterion in
procurement. Moreover, he raised the question if providers of care really knew what
patients want. What really matters to the specific patient? The answer for Mr. Allerup
is obvious: ask the patient and then center health care around patients and their
needs and wellbeing (Case study [8]: Public-private partnership (PPP) for a new way
to treat renal cancer).

Case study [8]: Public-private partnership (PPP) for a new way to treat renal
cancer

Situation: The Capital Region of Denmark and Roche Pharma started a public-
private partnership for patients with non-clear celled renal cancer.
Ambition: Tailoring the treatment to the patient’s need and thereby increasing
patient value overall. This will be achieved by collecting data on patient-reported
outcomes and real-world treatment data.
Outcome: First patient treatment will start in February 2020.

21www.g20.org |Accelerating Transformation Towards Sustainable Health Systems Through Value Based Health Care

Another example of adapting the mentality of achieving greater value for money in
health systems was provided by Singapore. The Singaporean Ministry of Health has
initiated a comprehensive health care transformation process that rests on three
pillars:

Value driven care
Bundled payments
Health technology assessment & value based pricing

The first pillar, value driven care, is implemented through a major initiative in
Singapore currently focusing on 17 conditions treated in an inpatient setting, with
the aim to improve outcomes and lowering costs. More details of the value driven
care initiative are provided in case study [9].

The second pillar, bundled payments (i.e. single price for all services required during
a patient’s entire episode of care), present an effective way to cap the costs of
treatment: payments are based on the diagnosed condition and not the volume of
procedures or the hours spent by a physician managing a case. Singapore plans to
introduce this bundled payment system by 2021.

For the third pillar, the Agency for Care Effectiveness (ACE) was established in
2015. The ACE conducts health technology assessments (HTA) to evaluate health
technologies in terms of clinical and cost effectiveness. HTA assessment agencies are
widespread in Europe, North America and Japan, and Singapore learned f rom those
countries. Moreover, ACE also engages in price negotiations with manufacturers to
ascertain value based pricing. As a striking example, Dr. Heng mentioned a 50%
price discount on a new medicine for treating Hepatitis C.

Case study [9]: Value driven care approach in Singapore

Situation: In 2018, the Singaporean Ministry of Health started a program for value
driven care. This program covers inpatient treatments in all public health care
institutions for a collection of 17 conditions. These conditions include Caesarean
section, total hip replacement and ischemic stroke.
Ambition: Maximizing the value of treatment by improving the outcomes while
lowering the costs. This can be achieved by generating learnings f rom patient
outcomes and cost data.
Outcome: So far, there are indications for improving value at the national level. One
of the next steps is to include patient-reported outcome measurements (PROMs).

22www.g20.org |Accelerating Transformation Towards Sustainable Health Systems Through Value Based Health Care

Singapore’s bundled payment approach is increasingly used elsewhere. Dr. Agnès
Soucat, Director for Health System Governance and Financing f rom the World Health
Organization, explained that bundling and blending different payment methods is
a prudent way forward in pursuit of improving quality. Estonia, a pioneer of bundling
payments in primary health care, has had such a system since the 2000s. In 2011, their
mix consisted of a basic allowance, capitation (predefined payments per person and
a certain period), fee for service and performance based payments. A prudent mix
of payments leverages the advantages of each kind while minimizing their caveats.

Panelists agreed that only when stakeholders join forces and organizations f rom
the public, private, and third sector realign their capabilities can a larger scale VBHC
implementation be feasible.

G. Large scale VBHC projects only succeed when roadblocks are removed

Italy is currently rolling out a successful VBHC project to encompass the whole country.
The Italian government already provides UHC to its entire population, irrespective
of any individual and social condition, and it is financed by a solidarity system. To
further improve patient experience and reduce costs, they have successfully tested
VBHC in pilots (Case study [10]: Lombardy). Now, Italy is striving to implement the
concept of VBHC universally. For this to become a reality, Dr. Giuseppe Ruocco,
Secretary General and Chief Medical Officer at the Italian Ministry of Health stressed
that VBHC needs to be fully embedded into the Italian health system and society.
For Italy, this strategy rests on an array of initiatives, among them:

The creation of a monitoring system to assess the burden of disease in two
dimensions: health implications and required investments
The measurement of value created by organizational processes and resource
consumption

Concrete measures that were taken by the government are the creation of

An e-Health National Plan, which provides health to patients outside of the
hospital setting
The new Health Pact, coordinating the reorganization of territorial health
care by newly developed collaborative organization network and
establishing pharmacies as first point of contact in the territories
The National Prevention Plan, promoting better and healthier lifestyles and
improving food safety. The National Prevention Plan also promotes health
literacy across the population and better training for health professionals.

Case study [10]: Lombardy

Situation: In 2011, Lombardy was one of the first in regions in Europe to pilot the
concept of the VBHC for treating patients with chronic diseases.
Ambition: Replacing the hospital-centric and f ragmented system with a system
that leverages collaboration between the various health actors and establishing a
single take-over fee. Furthermore, the care of chronic patients should be shifted
more to a home-based setting with the support of telemedicine.
Outcome: Successful projects tested in the initial phase were added to an initiative
called Nuove Reti Sanitarie (NRS), which aims to make those innovative approaches
a common practice in care delivery.

As described earlier in this report, India launched a similarly comprehensive and
disruptive health care project to benefit its population (Case study [2]: Ayushman
Bharat). A cornerstone of their initiative is that payment incentives are aligned with
the outcomes of treatments, e.g. pay for performance.

These nation-wide improvements in health care would have not been possible
without the willingness of legislators to allow disruption in health care. Legislators
need to introduce reforms to support VBHC models and cut down on regulatory,
institutional and legal VBHC barriers, as pinpointed by Mr. Christian Howell, the
vice president of Medtronic VBHC partnerships within the Americas region. Equally
important are ways to cultivate innovations in an ecosystem of aligned stakeholders
(Case study [11]: Partnership Lehigh Valley Health Network and Medtronic). Such
an ecosystem, Mr. Howell explained, is an environment that is mutually beneficial
because all stakeholders agree on critical components. This requires stakeholders
to agree on a strategic f ramework, governance model and operating model. In
practice this means that the provider’s and manufacturer’s teams need to speak
the same language, be aligned on what is measured, and aligned on how conflicts
are resolved. Furthermore, the legal f ramework needs to be discussed, and data
and information system inf rastructure built. Once the cornerstones of agreement
and the model have been set, the clinical intervention process can be initiated. This
intervention process can be split into three stages:

Benchmarking and design the intervention: Def ining the opportunity of
intervention, the measurement of the current state, the development
of value models and the design and building of the clinical intervention
approach
Creation of compliance mechanisms and business model
Kick-off and improvements: Taking the new clinical intervention live and
establishing continuous measurements and monitoring of the impact of the

24www.g20.org |Accelerating Transformation Towards Sustainable Health Systems Through Value Based Health Care

interventions allow for data-driven amendments of the intervention
For Mr. Howell, such an ecosystem between provider, payer and producer needs to
be in place before any clinical intervention starts in a specific location, e.g. a hospital
or provider network.

What was clear f rom the examples presented at the event was that VBHC models
require an open mind for new approaches to traditional problems and the
establishment of deeper relationships within healthcare stakeholders such as the
development of innovative solutions rather than sale of products by manufacturers,
which requires better alignment with the needs of providers and payers. Mr. Haddad
f rom Johnson & Johnson summarized this effectively; “To create viable VBHC systems,
we need:

Mindset change of all stakeholders including payers, patients, providers and
governments
Trust in the system between stakeholders, they should take risk and
experiment together
Flexibility in the system; where hospitals at the community level should be
given some autonomy to enter new kind of agreements, without having to
wait for the respective health care system as a whole to change”

Mr. Allerup f rom The Capital Region of Denmark emphasized that education and
training of stakeholders are instrumental and should not be neglected. In this
context, not only the education of citizens and patients but especially that of the
workforce needs to be improved. Dr. Omar Alshanqeety f rom the Program for

Case study [11]: Partnership Lehigh Valley Health Network and Medtronic

Situation: Lehigh Valley health network and Medtronic agreed on a 5-year strategic
partnership. This partnership serves to create a mutually beneficial environment
to deliver VBHC. Indications of interest include, among others, stroke, type I
diabetes, and heart failure.
Ambition: Improving health, care and satisfaction of patients while reducing
costs. This should be achieved by the co-creation of new applications, health
care platforms, beta-testing of new ideas and the sharing of data and an aligned
governance.
Outcome: It was a win-win for both parties. The health care system benefited f rom
a reduction in care variation while complying with the care pathway, better health
outcomes and lower cost of care. Medtronic profited f rom increased revenue, new
business opportunities and new expert knowledge in health care.

25www.g20.org |Accelerating Transformation Towards Sustainable Health Systems Through Value Based Health Care

Health Assurance and Purchasing in Saudi Arabia agreed and pointed out that the
new way of delivering care is different f rom the old way care has been delivered. This
necessitates a different understanding, a new mindset and new skills.

According to Ms. Colombo f rom the
OECD we need to rethink fundamentally
the training of health workers. Ms.
Colombo raised the question of how to
teach skills that allow professionals to
accelerate in a rapidly changing health
environment. They will need to learn how
to coordinate in such environments and
demonstrate an understanding of how
patients make decisions.

“We need different
medical skills for the 21st
century.”

Ms. Francesca Colombo, OECD

H. Practical learning is transferable within and across countries

Throughout the event there was a strong agreement that this was the first global
event where practical learning on global applications of VBHC models was shared.
Previously, similar conferences focused mainly on the theoretical aspects of value
driven health care models, lacked the richness of examples and were not global in
scope.

The richness and diversity of the shared examples were apparent to all participants,
and there was a shared consensus that the dialogue between stakeholders across
geographies and organizations would need to continue to drive forward in health
systems the transformation towards VBHC.

Everybody agreed that practical examples
f rom countries cannot be transferred
‘as-is’ without an understanding of the
different contexts. The stakeholders
need an understanding of which
learnings are transferrable to different
contexts, and which are context agnostic.
Such understanding is necessary
to accelerate the implementation
of VBHC both in similar and diverse
situations. One example is the VBHC
model implemented by Medtronic in
collaboration with several providers. The
first implementation took 18 months as
it required in-depth experimentation
and learning across the Medtronic

“ This is a journey that
several countries are
undertaking, and there
is a huge opportunity in
co learning.”

Dr. Omar Alshanqeety,
Program for Health Assurance
and Purchasing, Saudi Arabia

26www.g20.org |Accelerating Transformation Towards Sustainable Health Systems Through Value Based Health Care

organization. Thanks to this experience, the latest project was implemented in as
little as one month.

The need for international experimentation and knowledge sharing was reinforced
by Dr. Soucat, f rom the WHO, whom suggested to establish international
experimentation, in which new implementations of VBHC would introduce
controlled changes in the models chosen in order to comparatively test hypotheses.
Such experiments already exist; however, it is hard to currently draw conclusions due
to limited comparability.

Another example of an international organization promoting international learning
on VBHC is the WEF. To foster international learning, the WEF set up the Global
Coalition for Value in Healthcare to encourage Public-Private Partnerships on
VBHC. This platform partners with various stakeholders in health to co-design and
test innovative concepts promoting patient-centered health care. Partners include
universities, research institutes, management consultancies and many more.
According to Mr. Lucas Scherdel f rom WEF, such programs have shown signs of
success. In his view, what is needed now, is a global organization that will bundle all
the efforts and takes an active lead on global learning on and implementation of
VBHC, especially around the IT and data topic.

Dr. Chintan Maru, Founder of Leapf rog to Value at The Global Development
Incubator, emphasized that low-income and middle-income Countries (LMICs)
provide important VBHC lessons for all countries. This may come as a surprise, but
can be pinpointed on three aspects that promote innovation in LMICs:

Experimentations in those geographies are not restricted by legacy health
systems. They have little inf rastructure and do not suffer f rom structural
rigidness seen in developed countries. This rigidity is driven by regulatory
constraints and a medical education focused on knowledge acquisition
and not agility
LMICs, in contrast to high-income countries, have the political will and
necessity to increase health care spending to increase access
Innovation in LMICs is often driven by the ingenuity of the countries’
poor populations. As a powerful example f rom the tech sector, he
mentioned the rapid penetration of mobile payments in Af rica, driven
by the usage of prevalent mobile phones as a convenient payment vehicle.

To move forward with VBHC, LMICs need to further cultivate their own robust
ecosystem for experimentation. There is no fixed blueprint for transferring concepts
f rom high-income countries to LMIC. To further promote such experimentations,
those realities will need the necessary risk capital, and Dr. Maru suggests that some
bilateral development funds could be allocated for such purpose.

In line with Dr. Maru’s findings, the WHO offers support for country decision makers

27www.g20.org |Accelerating Transformation Towards Sustainable Health Systems Through Value Based Health Care

in a new online repository, the WHO compendium of innovative health technologies
for low-resource settings launching in 2020. This repository will provide information
on recommended interventions for therapeutic areas, type of services, age groups
and so forth. Additionally, it will have guidelines for necessary investments and give
orientation on a country specific level about costs and cost-effectiveness.

Furthermore, Ms. Herta Adam f rom the European Commission highlighted the
Commission’s support for countries in building strong, good quality and resilient
health care systems. In 2019, they expanded its efforts by entering in a partnership
program with the WHO to further improve health systems and promote UHC in over
100 countries.

I. Leveraging other sector learnings to improve the health care sector

The Event gathered valuable knowledge on the current state of the field. It translated
theoretical f rameworks into real-world examples f rom across the globe. Further
knowledge sharing events can help foster the urgently required alignment across
nations and other stakeholders.

Attendees at the Event and panelists suggested that future events may dedicate
some time to welcome experts f rom other fields, industries and sectors that have
successfully tackled similar issues facing health care today.

One f requently used comparison was re-iterated by Ms. Colombo f rom the OECD on
the aspect of safety: in the aviation industry errors and incidents are transparently
shared across the entire industry to prevent similar errors f rom happening again.
According to Ms. Colombo, health care needs a different safety culture, where we do
not panic on error, but value transparency.

Parallels to the tech industry were drawn by Mr. Howell f rom Medtronic. In the
company’s view, a platform in VBHC should work in a similar way like Uber connects
service providers with the end-users. Both stakeholders are aligned on the same
values, e.g. safe driving. This economy of trust needs to be governed:

How we share data, e.g. Uber App, no sharing of cell phone numbers
How to resolve disputes, e.g. exclusion of drivers with low ratings, reimbursement
of fees to end-user in case of dissatisfaction
How to measure outcomes, e.g. 5 star rating for drivers and passengers

Similarly, Mr. Bosch f rom the Catalan Ministry of Health, offered to the audience the
parallelism between VBHC models and Spotify. Spotify disrupted the music industry.
Traditionally, consumers used to pay by volume, paying a fee for service or buying
a CD or single song f rom iTunes. This business model pivoted to a flat rate model
in which users pay for value/outcome: value based reimbursement or flat rate for
unlimited consumption of music.

28www.g20.org |Accelerating Transformation Towards Sustainable Health Systems Through Value Based Health Care

The participants of the event agreed
that it was a huge success and had the
potential to lead to real change. Prof.
Atun stated that this has been the
first time that he has seen such rich
experiences on VBHC shared, indicating
that the field is really in the transition
f rom theoretical f rameworks toward
real-world applications.

“We have an opportunity
now to capture these
experiences and share
them globally”

Prof. Rifat Atun,
Harvard University

29www.g20.org |Accelerating Transformation Towards Sustainable Health Systems Through Value Based Health Care

Figure 5: Event Audience Poll. How
important is it to have a shared definition
of what value means?

Participants and panelists re-iterated the need to openly discuss and share
their experiences and learnings. Furthermore, they urged for convergence and
interoperability, especially on the IT and data & analytics dimensions. This discussion,
they stressed, should involve all stakeholders in the health and care ecosystem.

The Event participants felt that further convergence and agreement was needed on
the nomenclature and use of terms (Figure 5):

How do we define value?
How do we define platforms?
How we define outcomes?

Prof. Atun closed his final remarks with the call for greater solidarity and sustainability
in health systems to drive economic growth. VBHC provides an opportunity to build
health systems that are better prepared for the future.

PBL-038
October 2019

Design and development of the Diagnosis
Related Group (DRG)

Prospective payment rates based on Diagnosis Related Groups (DRGs) have been established as
the basis of Medicare’s hospital reimbursement system. The DRGs are a patient classification
scheme which provides a means of relating the type of patients a hospital treats (i.e., its case
mix) to the costs incurred by the hospital. The design and development of the DRGs began in the
late sixties at Yale University. The initial motivation for developing the DRGs was to create an
effective framework for monitoring the quality of care and the utilization of services in a hospital
setting. The first large-scale application of the DRGs was in the late seventies in the State of New
Jersey. The New Jersey State Department of Health used DRGs as the basis of a prospective
payment system in which hospitals were reimbursed a fixed DRG specific amount for each
patient treated. In 1982, the Tax Equity and Fiscal Responsibility Act modified the Section 223
Medicare hospital reimbursement limits to include a case mix adjustment based on DRGs. In
1983 Congress amended the Social Security Act to include a national DRG-based hospital
prospective payment system for all Medicare patients.

The evolution of the DRGs and their use as the basic unit of payment in Medicare’s hospital
reimbursement system represents a recognition of the fundamental role which a hospital’s case
mix plays in determining its costs. In the past, hospital characteristics such as teaching status and
bed size have been used to attempt to explain the substantial cost differences which exist across
hospitals. However, such characteristics failed to account adequately for the cost impact of a
hospital’s case mix. Individual hospitals have often attempted to justify higher cost by
contending that they treated a more “complex” mix of patients; the usual contention being that
the patients treated were “sicker.” Although there has been a consensus in the hospital industry
that a more complex case mix results in higher costs, the concept of case mix complexity had
historically lacked a precise definition. The development of the DRGs provided the first
operational means of defining and measuring a hospital’s case mix complexity.

The concept of case mix complexity
The concept of case mix complexity initially appears very straightforward. However, clinicians,
administrators and regulators have often attached different meanings to the concept of case mix
complexity depending on their backgrounds and purposes. The term case mix complexity has
been used to refer to an interrelated but distinct set of patient attributes which include severity
of illness, prognosis, treatment difficulty, need for intervention and resource intensity. Each of
these concepts has very precise meaning which describes a particular aspect of a hospital’s case
mix.

• Severity of illness. Refers to the relative levels of loss of function and mortality that may be
experienced by patients with a particular disease.

  • Design and development of the Diagnosis Related Group (DRG)
  • 2

    • Prognosis. Refers to the probable outcome of an illness including the likelihood of
    improvement or deterioration in the severity of the illness, the likelihood for recurrence and
    the probable life span.

    • Treatment difficulty. Refers to the patient management problems which a particular illness
    presents to the health care provider. Such management problems are associated with
    illnesses without a clear pattern of symptoms, illnesses requiring sophisticated and
    technically difficult procedures and illnesses requiring close monitoring and supervision.

    • Need for intervention. Relates to the consequences in terms of severity of illness that lack of
    immediate or continuing care would produce.

    • Resource intensity. Refers to the relative volume and types of diagnostic, therapeutic and
    bed services used in the management of a particular illness.

    When clinicians use the notion of case mix complexity, they mean that the patients treated have
    a greater severity of illness, present greater treatment difficulty, have poorer prognoses and
    have a greater need for intervention. Thus, from a clinical perspective case mix complexity refers
    to the condition of the patients treated and the treatment difficulty associated with providing
    care. On the other hand, administrators and regulators usually use the concept of case mix
    complexity to indicate that the patients treated require more resources which results in a higher
    cost of providing care. Thus, from an administrative or regulatory perspective case mix
    complexity refers to the resource intensity demands that patients place on an institution. While
    the two interpretations of case mix complexity are often closely related, they can be very
    different for certain kinds of patients. For example, while terminal cancer patients are very
    severely ill and have a poor prognosis, they require few hospital resources beyond basic nursing
    care.

    In the past, there has sometimes been confusion regarding the use and interpretation of the
    DRGs because the aspect of case mix complexity measured by the DRGs has not been clearly
    understood. The purpose of the DRGs is to relate a hospital’s case mix to the resource demands
    and associated costs experienced by the hospital. Therefore, a hospital having a more complex
    case mix from a DRG perspective means that the hospital treats patients who require more
    hospital resources but not necessarily that the hospital treats patients having a greater severity
    of illness, a greater treatment difficulty, a poorer prognosis or a greater need for intervention.

    Patient classification
    Given that the purpose of the DRGs is to relate a hospital’s case mix to its resource intensity, it
    was necessary to develop an operational means of determining the types of patients treated and
    relating each patient type to the resources they consumed. While all patients are unique, groups
    of patients have demographic, diagnostic and therapeutic attributes in common that determine
    their level of resource intensity. By developing clinically similar groups of patients with similar
    resource intensity, patients can be aggregated into meaningful patient classes. Moreover, if
    these patient classes covered the entire range of patients seen in an inpatient setting, then
    collectively they would constitute a patient classification scheme that would provide a means of

    Design and development of the Diagnosis Related Group (DRG)

    3

    establishing and measuring hospital case mix complexity. The DRGs were therefore developed as
    a patient classification scheme consisting of classes of patients who were similar clinically and in
    terms of their consumption of hospital resources.

    During the process of developing the DRG patient classification scheme, several alternative
    approaches to constructing the patient classes were investigated. Initially, a normative approach
    was used which involved having clinicians define the DRGs using the patient characteristics
    which they felt were important for determining resource intensity. There was a tendency for
    their definitions to include an extensive set of specifications, requiring information which might
    not always be collected through a hospital’s medical information system. If the entire range of
    patients were classified in this manner, it would ultimately lead to thousands of DRGs, most of
    which described patients seen infrequently in a typical hospital. It, therefore, became evident
    that the process of DRG definition would be facilitated if data from acute care hospitals could be
    examined to determine the general characteristics and relative frequency of different patient
    types. In addition, statistical algorithms applied to this data would be useful to suggest ways of
    forming DRGs that were similar in terms of resource intensity. However, it was also discovered
    that statistical algorithms applied to historical data in the absence of clinical input would not
    yield a satisfactory set of DRGs. The DRGs resulting from such a statistical approach, while similar
    in terms of resource intensity, would often contain patients with a diverse set of characteristics
    which could not be interpreted from a clinical perspective. Thus, it became apparent that the
    development of the DRG patient classification scheme required that physician judgment,
    statistical analysis and verification with historical data be merged into a single process. It was
    necessary to be able to examine large amounts of historical data with statistical algorithms
    available for suggesting alternative ways of forming DRGs but to do so in such a way that
    physicians could review the results at each step to insure that the DRGs formed were clinically
    coherent.

    Basic characteristics of the DRG patient classification
    scheme

    Given the limitations of previous patient classification schemes and the experience of
    attempting to develop DRGs with physician panels and statistical analysis, it was concluded that
    in order for the DRG patient classification scheme to be practical and meaningful it should have
    the following characteristics:

    1. The patient characteristics used in the definition of the DRGs should be limited to
    information routinely collected on hospital abstract systems.

    2. There should be a manageable number of DRGs which encompass all patients seen on an
    in-patient basis.

    3. Each DRG should contain patients with a similar pattern of resource intensity.

    4. Each DRG should contain patients who are similar from a clinical perspective (i.e., each class
    should be clinically coherent).

    Design and development of the Diagnosis Related Group (DRG)

    4

    Restricting the patient characteristics used in the definition of the DRGs to those readily
    available insured that the DRGs could be extensively applied. Currently, the patient information
    routinely collected includes age, principal diagnosis, secondary diagnoses and the surgical
    procedures performed. Creating DRGs based on information that is only collected in a few
    settings or on information which is difficult to collect or measure would have resulted in a
    patient classification scheme which could not be applied uniformly across hospitals. That is not
    to say that information beyond that currently collected might not be useful for defining the
    DRGs. As additional information becomes routinely available it must be evaluated to determine
    if it might result in improvements in the ability to classify patients.

    Limiting the number of DRGs to manageable numbers (i.e., hundreds of patient classes, not
    thousands) insures that for most of the DRGs, a typical hospital will have enough experience to
    allow meaningful comparative analysis to be performed. If there were only a few patients in
    each DRG, it would be difficult to detect patterns in case mix complexity and cost performance
    and to communicate the results to the physician staff.

    The resource intensity of the patients in each DRG must be similar in order to establish a
    relationship between the case mix of a hospital and the resources it consumes. Similar resource
    intensity means that the resources used are relatively consistent across the patients in each
    DRG. However, some variation in resource intensity will remain among the patients in each DRG.
    In other words, the definition of the DRG will not be so specific that every patient is identical,
    but the level of variation is known and predictable. Thus, while the precise resource intensity of
    a particular patient cannot be predicted by knowing to which DRG he belongs, the average
    pattern of resource intensity of a group of patients in a DRG can be accurately predicted.

    Since one of the major applications of the DRGs is as a means of communicating with the
    physician community, the patients in each DRG must be similar from a clinical perspective. In
    other words, the definition of each DRG must be clinically coherent. The concept of clinical
    coherence requires that the patient characteristics included in the definition of each DRG relate
    to a common organ system or etiology and that a specific medical specialty should typically
    provide care to the patients in the DRG. For example, patients who are admitted for a D&C or a
    Tonsillectomy are similar in terms of most measures of resource intensity such as length of stay,
    preoperative stay, operating room time and use of ancillary services. However, different organ
    systems and different medical specialties are involved. Thus, the requirement that the DRGs be
    clinically coherent precludes the possibility of these types of patients being in the same DRG.

    A common organ system or etiology and a common clinical specialty is a necessary but not
    sufficient requirement for a DRG to be clinically coherent. In addition, all available patient
    characteristics which medically would be expected to consistently affect resource intensity
    should be included in the definition of the DRG. Furthermore, a DRG should not be based on
    patient characteristics which medically would not be expected to consistently affect resource
    intensity. For example, patients with appendicitis may or may not have peritonitis. Although
    these patients are the same from an organ system, etiology and medical specialist perspective,
    the DRG definitions must form separate patient classes, since the presence of peritonitis would
    be expected to consistently increase the resource intensity of the appendicitis patients. On the
    other hand, sets of unrelated surgical procedures cannot be used to define a DRG since there

    Design and development of the Diagnosis Related Group (DRG)

    5

    would not be a medical rationale to substantiate that the resource intensity would be expected
    to be similar.

    The definition of clinical coherence is, of course, dependent on the purpose for the formation of
    the DRG classification. For the DRGs, the definition of clinical coherence relates to the medical
    rationale for differences in resource intensity. If, on the other hand, the purpose of the DRGs
    related to mortality, the patient characteristics which were clinically coherent and, therefore,
    included in the DRG definitions might be different. Finally, it should be noted that the
    requirement that the DRGs be clinically coherent caused more patient classes to be formed than
    would be necessary for explaining resource intensity alone.

    Formation of the DRGs
    The process of forming the DRGs was begun by dividing all possible principal diagnoses into 23
    mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC).
    Two new MDCs were created in the eighth version of the DRGs. The 25 MDCs are listed in table
    1.

    The MDCs were formed by physician panels as the first step toward insuring that the DRGs
    would be clinically coherent. The diagnoses in each MDC correspond to a single organ system or
    etiology and in general are associated with a particular medical specialty. Thus, in order to
    maintain the requirement of clinical coherence, no final DRG could contain patients in different
    MDCs. In general, each MDC was constructed to correspond to a major organ system (e.g.,
    Respiratory System, Circulatory System, Digestive System) rather than etiology (e.g.,
    malignancies, infectious diseases). This approach was used since clinical care is generally
    organized in accordance with the organ system affected, and not the etiology. Thus, diseases
    involving both a particular organ system and a particular etiology (e.g., malignant neoplasm of
    the kidney) were assigned to the MDC corresponding to the organ system involved. However,
    not all diseases or disorders could be assigned to an organ system-based MDC and a number of
    residual MDCs were created (e.g., Systemic Infectious Diseases, Myeloproliferative Diseases and
    Poorly Differentiated Neoplasms). For example, the infectious diseases food poisoning and
    Shigella dysenteriae are assigned to the Digestive System MDC while pulmonary tuberculosis is
    assigned to the Respiratory System MDC. On the other hand, infectious diseases such as miliary
    tuberculosis and septicemia which usually involve the entire body are assigned to the Systemic
    Infectious Disease MDC.

    Once the MDCs were defined each MDC was evaluated to identify those additional patient
    characteristics which would have a consistent effect on the consumption of hospital resources.
    Since the presence of a surgical procedure which required the use of the operating room would
    have a significant effect on the type of hospital resources (e.g., operating room, recovery room,
    anesthesia) used by a patient, most MDCs were initially divided into medical and surgical groups.
    The medical-surgical distinction is also useful in further defining the clinical specialty involved.

    Patients were considered surgical if they had a procedure performed which would require the
    use of the operating room. Since the patient data generally available does not precisely indicate
    whether a patient was taken to the operating room, surgical patients were identified based on

    Design and development of the Diagnosis Related Group (DRG)

    6

    the procedures which were performed. Physician panels classified every possible procedure
    code based on whether the procedure would in most hospitals be performed in the operating
    room.

    Thus, closed heart valvotomies, cerebral meninges biopsies and total cholecystectomies would
    be expected to require the operating room while thoracentesis, bronchoscopy and skin sutures
    would not. If a patient had any procedure performed which was expected to require the
    operating room that patient would be classified as a surgical patient. A complete list of all the
    procedures expected to require the operating room is contained in Appendix E.

    Once each MDC was divided into medical and surgical categories, then, in general, the surgical
    patients were further defined based on the precise surgical procedure performed while the
    medical patients were further defined based on the precise principal diagnosis for which they
    were admitted to the hospital. The general structure of a typical MDC is shown by the tree
    diagram found at the end of this chapter (figure 1). In general, specific groups of surgical
    procedures were defined to distinguish surgical patients according to the extent of the surgical
    procedure performed. For example, the procedure classes defined for the Endocrine, Nutritional
    and Metabolic MDC are amputations, procedures for obesity, skin grafts and wound
    debridements, adrenal and pituitary procedures, parathyroid procedures, thyroid procedures,
    thyroglossal procedures and other procedures relating to Endocrine, Nutritional or Metabolic
    diseases.

    Since a patient can have multiple procedures related to their principal diagnosis during a
    particular hospital stay, and a patient can be assigned to only one surgical class, the surgical
    classes in each MDC were defined in a hierarchical order. Patients with multiple procedures
    would be assigned to the surgical class highest in the hierarchy.

    Thus, if a patient received both an extraction of endometrium (D&C in ICD-9-CM) and a resection
    of uterus (hysterectomy in ICD-9-CM), the patient would be assigned to the hysterectomy
    surgical class. It should be noted that as a result of the surgical hierarchy the ordering of the
    surgical procedures on the patient abstract has no influence on the assignment of the surgical
    class and DRG. Appendix D lists the surgical hierarchy for each MDC.

    In general, specific groups of principal diagnoses were defined for medical patients. Usually the
    medical classes in each MDC would include a class for neoplasms, symptoms and specific
    conditions relating to the organ system involved. For example, the medical classes for the
    Respiratory System MDC are ventilator support, pulmonary embolism, infections and
    inflammations, neoplasms, chest trauma, pleural effusion, pulmonary edema and respiratory
    failure, chronic obstructive pulmonary disease, simple pneumonia and pleurisy, interstitial lung
    disease, pneumothorax, bronchitis and asthma, respiratory signs and symptoms and other
    respiratory diagnoses.

    In each MDC there is usually a medical and a surgical class referred to as “other medical
    diseases” and “other surgical procedures,” respectively. The “other” medical and surgical classes
    are not as precisely defined from a clinical perspective. The other classes would include
    diagnoses or procedures which were infrequently encountered or not well defined clinically. For
    example, the “other” medical class for the Respiratory System MDC would contain the diagnoses
    “other somatoform disorders” and “congenital malformation of the respiratory system,” while
    the “other” surgical class for the female reproductive MDC would contain the surgical
    procedures “excision of liver” (liver biopsy in ICD-9-CM) and “inspection of peritoneal cavity”
    (exploratory laparotomy in ICD-9-CM).

    The “other” surgical category contains surgical procedures which, while infrequent, could still
    reasonably be expected to be performed for a patient in the particular MDC. There are,
    however, also patients who receive surgical procedures which are completely unrelated to the
    MDC to which the patient was assigned. An example of such a patient would be a patient with a
    principal diagnosis of pneumonia whose only surgical procedure is a destruction of prostate
    (transurethral prostatectomy in ICD-9-CM). Such patients are assigned to a surgical class referred
    to as “unrelated operating room procedures.” These patients are ultimately never assigned to a
    well-defined DRG.

    The process of defining the surgical and medical classes in an MDC required that each surgical or
    medical class be based on some organizing principle. Examples of organizing principles would be
    anatomy, surgical approach, diagnostic approach, pathology, etiology or treatment process. In
    order for a diagnosis or surgical procedure to be assigned to a particular class, it would be
    required to correspond to the particular organizing principle for that class. For example, in the
    Urinary System MDC a surgical group was formed for all patients with a procedure on the
    urethra (i.e., organizing principle based on anatomy). This surgical group was then further
    divided based on whether the procedure performed was transurethral (i.e., organizing principle
    based on surgical approach).

    Figure 1 displays the basic structure of the DRG. Until the eighth version, the first step in the
    determination of the DRG had been the assignment of the appropriate MDC based on the
    principal diagnosis. The eighth version of the DRGs contained the first departure from the use of
    principal diagnosis as the initial variable in DRG assignment, when the initial step in DRG
    assignment was based on procedure (PRE MDC). If a patient has a heart transplant or implant of
    heart assist system, ECMO or tracheostomy, liver transplant and/or intestinal transplant, bone
    marrow transplant, lung transplant simultaneous pancreas/kidney transplant, or pancreas
    transplant, then the patient is assigned to these DRGs independent of the MDC of the principal
    diagnosis. Heart, intestinal, liver, bone marrow, lung, pancreas/kidney and pancreas transplants
    are very resource intensive and can be performed for diagnoses in many different MDCs.
    Tracheostomies are performed primarily for patients on long term ventilator support and
    therefore such patients are very resource intensive. The eighth version also created two new
    MDCs for patients with multiple trauma (MDC 24) and patients with an HIV infection (MDC 25).
    Assignment to MDC 24 and 25 is based on both principal and secondary diagnoses. An
    assignment to MDC 24 is based on the presence of two or more significant traumas in different
    body systems (e.g. a fractured skull and a fractured femur). Assignment to MDC 25 is based on a
    principal diagnosis of an HIV infection or a principal diagnosis of an HIV related complication

    Design and development of the Diagnosis Related Group (DRG)

    9

    combined with a secondary diagnosis of an HIV infection (e.g. principal diagnosis of
    pneumocystosis and a secondary diagnosis of an HIV infection).

    Once the medical and surgical classes for an MDC were formed, each class of patients was
    evaluated to determine if complications, comorbidities, the patient’s age or discharge status
    consistently affected the consumption of hospital resources. Physician panels classified each
    diagnosis code based on whether the diagnosis, when present as a secondary condition, would
    be considered a substantial complication or comorbidity. A substantial complication or
    comorbidity was defined as a condition, that because of its presence with a specific principal
    diagnosis would cause an increase in length of stay by at least one day in at least 75 percent of
    the patients. For example, sarcoidosis of lung, chronic obstructive pulmonary disease and
    pneumococcal pneumonia are considered substantial complications or comorbidities for certain
    diseases, while nontoxic diffuse goiter and essential hypertension are not. Each medical and
    surgical class within an MDC was tested to determine if the presence of any substantial
    comorbidities or complications would consistently affect the consumption of hospital resources.
    For example, the presence of complications or comorbidities was not significant for patients
    receiving a median nerve release (carpal tunnel release in ICD-9-CM) but was very significant for
    patients with arrhythmia and conduction disorders. The same basic list of complications and
    comorbidities are used across most DRGs. However, depending on the principal diagnosis of the
    patient, some diagnoses in the basic list of complications and comorbidities may be excluded if
    they are closely related to the principal diagnosis. For example, urinary retention is a
    complication or comorbidity for a patient admitted for congestive heart failure but not for a
    patient admitted for enlarged prostate. In addition, in some cases such as newborns or acute
    myocardial infarction patients, special complications and comorbidity definitions were used in
    defining the DRGs.

    The final variable used in the definition of the DRGs was the patient discharge status. Separate
    DRGs were formed for newborns if the patients were transferred to another acute care facility.
    In addition, separate DRGs were formed for patients with alcoholism or drug abuse who left
    against medical advice and for acute myocardial infarction patients and newborns who died.

    For versions 2-24 of the DRGs, the further subdivisions of some medical and surgical DRGs was
    primarily based on the presence or absence of a CC or pediatric age (0-17). For example, in DRG
    version 24 there were 115 pairs of DRGs subdivided based on the presence or absence of a CC
    and 43 pediatric DRGs (age 0-17). Beginning with version 25 the use of CCs and patient age was
    completely revised. The revisions were so extensive that the version 25 DRGs were renamed to
    be the Medicare Severity DRGs (MS-DRGs).

    Except for new diagnosis codes that were added to ICD-9-CM after FY1984 (e.g., HIV), the CC list
    of diagnoses used in the DRGs remained virtually identical to the original CC list used in FY1984.
    As a result of the changes that occurred in hospitals during the first 22 years of PPS, the CC list
    had lost much of its power to discriminate hospital resource use. Better coding of secondary
    diagnoses, stricter criteria for extended hospital stays, increased availability of post acute care
    services and the shift to outpatient care resulted in most patients (nearly 80 percent) admitted
    to hospitals having a CC. Therefore, in version 25 (MS-DRGs) the diagnoses comprising the CC list
    were completely redefined. The revised CC list is primarily comprised of significant acute
    disease, acute exacerbations of significant chronic diseases, advanced or end stage chronic

    Design and development of the Diagnosis Related Group (DRG)

    10

    diseases and chronic diseases associated with extensive debility. In general, most chronic
    diseases were not included on the revised CC list. For a patient with a chronic disease, a
    significant acute manifestation of the chronic disease was required to be present and coded for
    the patient to be assigned a CC. The revision of the CC list reduced the number of Medicare
    patients with a CC from approximately 80 percent to 40 percent.

    In addition, to the revision of the CC list, each CC was also categorized as a major CC or a CC (i.e.,
    non major CC) based on relative resource use. Approximately, 12 percent of all diagnoses codes
    were classified as a major CC, 24 percent as a CC and 64 percent as a non CC. Diagnoses closely
    associated with mortality (ventricular fibrillation, cardiac arrest, shock and respiratory arrest)
    were assigned as a major CC if the patient lived but as a non CC if the patient died.

    The major CC, CC and non CC categorization was used to subdivide the surgical and medical
    DRGs into up to three levels with a patient being assigned to the most extreme level (e.g., a
    patient with an MCC and a CC is assigned to the MCC level). Before subdividing the medical and
    surgical DRGs into CC levels all the pediatric age distinctions were removed from the DRGs. To
    create the MS-DRGs, individual DRGs were subdivided into three, two or one level depending on
    the CC impact on resources used for that patient. The two way subdivision either created a
    separate level for just the major CC patients or a separate level for the non CC patients. The CC
    levels relate to the relative severity of illness of the patient. In the MS-DRG version 25, 152 DRGs
    had 3 CC levels, 107 DRGs had two CC levels and 76 DRGs had no CC levels resulting in 745
    MS-DRGs which is a net increase of 207 DRGs over the 538 in version 24. The following table
    provides the MS-DRG version 37.0 subdivisions:

    In MS-DRG version 37.0 there are 72,184 diagnoses and 77,559 procedures.

    The Deficit Reduction Act of 2005 (P.L.109-171) requires CMS to eliminate any increase in
    payment due to the occurrence of selected post admission complications, known as Hospital
    Acquired Conditions (HACs). HACs are harmful events (e.g. accidental laceration during a
    procedure) or negative outcomes (e.g. decubitus ulcer) that result from the processes of care
    and treatment rather than from a natural progression of underlying illness. Under the Medicare
    inpatient prospective payment system, the occurrence of an HAC can result in a higher payment
    because the presence of the HAC diagnosis may cause the patient to be assigned to a
    higher-paying MS-DRG, in effect financially rewarding poor quality care.

    Design and development of the Diagnosis Related Group (DRG)

    11

    When IPPS was implemented the standard claim form did not contain a specification of whether
    a secondary diagnosis was present on admission (POA). The Deficit Reduction Act requires
    hospitals to report a POA indicator for all diagnoses beginning in fiscal year 2008. The reporting
    of the POA indicator allows complications that occur post admission to be identified. The Deficit
    Reduction Act requires that the post admission complications selected as HACs be (1) high cost,
    high volume, or both; (2) be a CC or Major CC in MS-DRGs and (3) be reasonably preventable
    through the application of evidence-based guidelines. For Fiscal Year 2009, CMS designated 12
    conditions as HACs:

    1. Foreign object retained after surgery

    2. Air embolism

    3. Blood incompatibility

    4. Stage III and IV pressure ulcers

    5. Falls and trauma

    6. Catheter-associated urinary tract infection (UTI)

    7. Vascular catheter-associated infection

    8. Surgical site infection – Mediastinitis following Coronary Artery Bypass Surgery (CABG)

    9. Manifestations of poor glycemic control

    10. Deep vein thrombosis (DVT) /pulmonary embolism (PE) following total knee replacement
    or hip replacement

    11. Surgical site infection following bariatric surgery

    12. Surgical site infection following certain orthopedic procedures of spine, shoulder or
    elbow

    For Fiscal Year 2013, two additional HACs were added:

    13. Surgical site infection following cardiac device procedures

    14. Iatrogenic pneumothorax with venous catheterization.

    If an HAC diagnosis is present at admission, it will continue to be classified as a CC or major CC
    and allowed to affect the MS-DRG assignment. However, if the HAC diagnosis is not present at
    admission, it will no longer be classified as a CC or major CC and will not affect MS-DRG
    assignment. The exclusion of an HAC diagnosis from MS-DRG assignment does not necessarily
    mean the MS-DRG will change. Some MS-DRGs are not differentiated by the presence of a CC or
    Major CC. For such MS-DRGs the exclusion of an HAC diagnosis will have no impact on MS-DRG
    assignment. Further, if in addition to an HAC diagnosis there are non-HAC diagnoses present that
    are a CC or major CC, the exclusion of the HAC diagnosis may not change the MS-DRG. Beginning
    in Fiscal Year 2009, HAC diagnoses are excluded from MS-DRG assignment.

    The actual process of forming the DRGs was highly iterative, involving a combination of
    statistical results from test data with clinical judgment. At any point during the definition of the
    DRGs there would often be several patient characteristics which appeared important for
    understanding the impact on hospital resources. The selection of the patient characteristics to

    Design and development of the Diagnosis Related Group (DRG)

    12

    be used and the order in which they would be used was a complex task with many factors
    examined and weighed simultaneously. A complete list of the MS-DRGs is contained in Appendix
    A in the MS-DRG definitions manual.

    There are several MS-DRGs which contain patients whose medical record abstracts contain
    clinically inconsistent or invalid information. For example, there are MS-DRGs for patients for
    whom all their operating room procedures performed are unrelated to the major diagnostic
    category of the patient’s principal diagnosis. Typically, these are patients admitted for a
    particular diagnosis requiring no surgery, who develop a complication unrelated to the principal
    diagnosis and have an operating room procedure performed for the complication or have a
    diagnostic procedure performed for another concurrent diagnosis. The unrelated operating
    room procedures have been divided into two groups based on hospital resource use: extensive
    and non-extensive. For example, a patient with a principal diagnosis of congestive heart failure
    who develops acute cholecystitis and whose only procedure is a resection of gallbladder
    (cholecystectomy in ICD-9-CM) will be assigned to the extensive unrelated procedure MS-DRG
    since a cholecystectomy is considered an extensive procedure. However, if a patient has a
    principal diagnosis of arrhythmia and has a diagnostic excision of breast (breast biopsy in
    ICD-9-CM) discovered while in the hospital, the patient will be assigned to the non- extensive
    unrelated MS-DRG since the biopsy is considered a non-extensive procedure. The complete
    definition of unrelated operating room procedures is contained in Appendix F.

    When a principal diagnosis is coded which, although it is a valid ICD-10-CM code, is not precise
    enough to allow the patient to be assigned to a clinically coherent MS-DRG the patient is
    assigned to a diagnosis invalid as principal diagnosis MS-DRG. For example, ICD-10-CM code
    O0930 is an unspecified complication of pregnancy with the episode of care unspecified. Thus,
    this diagnosis code does not indicate the type of complication nor whether the episode of care
    was antepartum, postpartum or for delivery. Since the MS-DRG definitions assign patients to
    different sets of MS-DRGs depending on whether the episode of care was antepartum,
    postpartum or for delivery, a patient with a principal diagnosis of O0930 must be assigned to the
    diagnosis invalid as principal diagnosis MS-DRG.

    It should be noted that patients with a principal diagnosis not typically considered a reason for
    hospitalization such as Z413 (ear piercing) are not assigned to the diagnosis invalid as principal
    diagnosis MS-DRG but are assigned a MS-DRG in the MDC most related to the diagnosis.

    Patients are assigned to an ungroupable MS-DRG if certain types of medical records errors which
    may affect MS-DRG assignment are present. Patients with an invalid or non-existent ICD-10-CM
    code as principal diagnosis will be assigned to the ungroupable MS-DRG. Patients will also be
    assigned to the ungroupable MS-DRG if their sex, or discharge status is both invalid and
    necessary for MS-DRG assignment. For example, if a patient has a non-numeric discharge status
    and has a principal diagnosis of an acute myocardial infarction, the patient will be assigned to
    the ungroupable MS-DRG since patients with acute myocardial infarction will be assigned to
    different MS-DRGs depending on whether their discharge status is alive or died. On the other
    hand, if the same patient had a principal diagnosis of hypertension, the assignment would not be
    to the ungroupable MS-DRG since discharge status is not used in the determination of the
    MS-DRG for hypertensive patients.

    The DRGs were originally developed at the Yale University School of Organization and
    Management during the 1970’s under contract to the Centers for Medicare and Medicaid
    Services (formerly Health Care Financing Administration). The second version and all subsequent
    versions of the DRG definitions have been updated by 3M Health Information Systems under
    contract with CMS. All versions of the DRGs, since the inception of the Medicare Prospective
    Payment System, are summarized in the following table.

    Summary
    The DRGs, as they are now defined, form a manageable, clinically coherent set of patient classes
    that relate a hospital’s case mix to the resource demands and associated costs experienced by
    the hospital. DRGs are defined based on the principal diagnosis, secondary diagnoses, surgical
    procedures, age, sex and discharge status of the patients treated. Through DRGs, hospitals can
    gain an understanding of the patients being treated, the costs incurred and within reasonable
    limits, the services expected to be required. The classification of patients into DRGs is a
    constantly evolving process. As coding schemes change, as more comprehensive data is
    collected or as medical technology or practice changes, the DRG definitions will be reviewed and
    revised.

    DRG versions 2.0–32.0 were defined using the ICD-9-CM codeset. MS-DRG v37.0 was
    implemented using the ICD-10-CM/PCS codeset effective October 1, 2019.

    What Is Value-Based Healthcare?
    Explore the definition, benefits, and examples of value-based healthcare. How does value-based healthcare
    translate to new delivery models?

    NEJM Catalyst

    This article appeared in NEJM Catalyst prior to the launch of the NEJM Catalyst Innovations in Care Delivery journal. Learn
    more.

    Value-based healthcare is a healthcare delivery model in which providers, including hospitals and physicians, are paid
    based on patient health outcomes. Under value-based care agreements, providers are rewarded for helping patients
    improve their health, reduce the effects and incidence of chronic disease, and live healthier lives in an evidence-based
    way.

    Value-based care differs from a fee-for-service or capitated approach, in which providers are paid based on the amount
    of healthcare services they deliver. The “value” in value-based healthcare is derived from measuring health outcomes
    against the cost of delivering the outcomes.

    What Are the Benefits of Value-Based Healthcare Delivery?

    The benefits of a value-based healthcare system extend to patients, providers, payers, suppliers, and society as a whole.

    1. Patients spend less money to achieve better health. Managing a chronic disease or condition like cancer,
    diabetes, high blood pressure, COPD, or obesity can be costly and time-consuming for patients. Value-based care
    models focus on helping patients recover from illnesses and injuries more quickly and avoid chronic disease in the
    first place. As a result, patients face fewer doctor’s visits, medical tests, and procedures, and they spend less money
    on prescription medication as both near-term and long-term health improve.

    2. Providers achieve efficiencies and greater patient satisfaction. While providers may need to spend more
    time on new, prevention-based patient services, they will spend less time on chronic disease management. Quality
    and patient engagement measures increase when the focus is on value instead of volume. In addition, providers are
    not placed at the financial risk that comes with capitated payment systems. Even for-profit providers, who can
    generate higher value per episode of care, stand to be rewarded under a value-based care model.

    3. Payers control costs and reduce risk. Risk is reduced by spreading it across a larger patient population. A
    healthier population with fewer claims translates into less drain on payers’ premium pools and investments. Value-
    based payment also allows payers to increase efficiency by bundling payments that cover the patient’s full care
    cycle, or for chronic conditions, covering periods of a year or more.

    4. Suppliers align prices with patient outcomes. Suppliers benefit from being able to align their products and
    services with positive patient outcomes and reduced cost, an important selling proposition as national health
    expenditures on prescription drugs continue to rise. Many healthcare industry stakeholders are calling for
    manufacturers to tie the prices of drugs to their actual value to patients, a process that is likely to become easier with
    the growth of individualized therapies.

    5. Society becomes healthier while reducing overall healthcare spending. Less money is spent helping
    people manage chronic diseases and costly hospitalizations and medical emergencies. In a country where
    healthcare expenditures account for nearly 18% of Gross Domestic Product �GDP�, value-based care has the
    promise to significantly reduce overall costs spent on healthcare.

    How Does Value-Based Healthcare Translate to New Delivery Models?

    The proliferation of value-based healthcare is changing the way physicians and hospitals provide care. New healthcare
    delivery models stress a team-oriented approach to patient care and sharing of patient data so that care is coordinated
    and outcomes can be measured easily. Two examples are reviewed here.

    Value-Based Care Models: Medical Homes

    In value-based healthcare models, medical care does not exist in silos. Instead, primary, specialty, and acute care are
    integrated, often in a delivery model called a patient-centered medical home �PCMH�. A medical home isn’t a physical
    location. Instead, it’s a coordinated approach to patient care, led by a patient’s primary physician who directs a patient’s
    total clinical care team.

    PCMHs rely on the sharing of electronic medical records �EMRs� among all providers on the coordinated care team.
    The goal of EMRs is to put crucial patient information at each provider’s fingertips, allowing individual providers to see
    results of tests and procedures performed by other clinicians on the team. This data sharing has the potential to reduce
    redundant care and associated costs.

    Value-Based Care Models: Accountable Care Organizations

    Accountable care organizations �ACOs� were originally designed by the Centers for Medicare & Medicaid Services
    �CMS� to provide high-quality medical care to Medicare patients. In an ACO, doctors, hospitals, and other healthcare
    providers work as a networked team to deliver the best possible coordinated care at the lowest possible cost. Each
    member of the team shares both risk and reward, with incentives to improve access to care, quality of care, and patient
    health outcomes while reducing costs. This approach differs from fee-for-service healthcare, in which individual
    providers are incentivized to order more tests and procedures and manage more patients in order to get paid more,
    regardless of patient outcomes.

    F E B R U A RY �, ����

    Like PCMHs, ACOs are patient-centered organizations in which the patient and providers are true partners in care
    decisions. Also like PCMHs, ACOs stress coordination and data sharing among team members to help achieve these
    goals among their entire patient population. Clinical and claims data are also shared with payers to demonstrate
    improvements in outcomes such as hospital readmissions, adverse events, patient engagement, and population health.

    Hospital Value-Based Purchasing

    Under CMS’s Hospital Value-Based Purchasing Program �VBP�, acute care hospitals receive adjusted payments based
    on the quality of care they deliver. According to the CMS website, the program encourages hospitals to improve the
    quality and safety of acute inpatient care for all patients by:

    Eliminating or reducing adverse events �healthcare errors resulting in patient harm�
    Adopting evidence-based care standards and protocols that make the best outcomes for the most patients
    Changing hospital processes to create better patient care experiences
    Increasing care transparency for consumers
    Recognizing hospitals that give high-quality care at a lower cost to Medicare

    CMS is expected to continue to refine its VBP measurements, making it important for hospitals to continuously
    improve their clinical outcomes so they can simultaneously improve reimbursement and their reputation among
    healthcare consumers.

    What Is the Future of Value-Based Healthcare?

    Moving from a fee-for-service to a fee-for-value system will take time, and the transition has proved more difficult than
    expected. As the healthcare landscape continues to evolve and providers increase their adoption of value-based care
    models, they may see short-term financial hits before longer-term costs decline. However, the transition from fee-for-
    service to fee-for-value has been embraced as the best method for lowering healthcare costs while increasing quality
    care and helping people lead healthier lives.

    Learning Objectives

    Upon completion of this chapter, the student should be
    able to:
    1. Describe responsibility for and methods of assessing and

    regulating technological developments in health care;
    2. Describe methods of health facility accreditation and

    peer review;
    3. Describe the concept of total quality management;
    4. Identify and discuss ethical and legal issues in national

    health systems;
    5. Apply ethical considerations to health issues in his or

    her home setting.

    INTRODUCTION

    Management of a production or a service system requires
    attention to the quality of personnel as much as to the system
    in which they work. Their motivation and sense of participa-
    tion, the scientific and technological level of the program,
    and the legal and ethical standards of individual providers
    and of the system as a whole, are all important to the quality
    of care provided and equity of health status achieved.

    Quality is the result of input and process, and is measured
    by outcome or performance indicators as well as perception
    of the service by the patients, the staff, and the community
    as a whole. Input refers to the institutional and financial
    resources for education, human resources, supplies, medica-
    tions, vaccines, diagnostic capacity, and services available.
    Process refers to the use of those resources, including peer
    group expectations of professionalism. Outcomes generally
    include measures of morbidity, mortality, and functional sta-
    tus of the patient and the population. Defining and measuring
    achievements of national health objectives and targets, the
    methods of financing services, and the efficiency of organi-
    zation help to determine quality. Training, supply, and dis-
    tribution of health personnel are all determinants of access
    to and quality of care. Continuous and adequate availability
    of essential preventive, diagnostic, and treatment services,
    as well as accountability and internal methods of promoting
    standards, are all elements of the quality of a health service

    771

    for the individual, the population as a whole, and groups
    within the population with special needs.

    The content and standards of service are assessed
    through organized review by professional peers within
    an institution, and from outside. Peer review within an
    institution and external evaluation by accreditation or
    governmental inspection, based on cumulative evidence
    and the recognized current “state of the art”, contribute
    to accountability and improved quality of care. Continu-
    ous quality improvement (CQI) among health care teams
    and organizations includes regular practice assessments,
    evidence gathering, remediation, and re-evaluation, which
    will be discussed later in this chapter. The perception of
    the services by the community, along with the knowledge,
    attitudes, beliefs, and practices of health, are all vital to
    improvement of health status.

    Health-related technology is also in a continuing state
    of change. Systematic review and absorption of new scien-
    tific knowledge, technology, and innovations are essential
    to promote and renew health care methods. Public health
    serves in a regulatory role to assure high-quality care to the
    individual and the community. New technology, whether in
    the form of diagnostic procedures, new drugs, devices, or
    vaccines, or new types of health personnel, requires evalu-
    ation for effectiveness and appropriateness to the system.

    Technology assessment also involves epidemiological and
    economic aspects of effectiveness. Failure to continuously
    monitor developments and to assimilate those that are demon-
    strably successful is an ethical and management failure which
    tragically costs many millions of lives from preventable dis-
    eases yearly, such as in delayed adoption of well-proven vac-
    cines or tobacco restriction legislation. This is due to political
    failure even more than professional weakness, and constitutes
    one of the saddest ethical dilemmas of public health: failure
    to convince policy makers of the prime importance of health
    promotion and disease prevention in the health sector.

    Ethics and law in public health reflect the values of a
    society. They inevitably evolve as they face dramatic social,
    economic, demographic, and political changes; new health
    challenges; and new technological and scientific possibili-
    ties for improving health. Ethics are the foundation of the
    value systems of a society and thus of its health concepts.

    772

    Biblical sources articulated values of the Ten Command-
    ments, Sanctity of Human Life, Improve the World, along
    with the Hippocratic Oath of physicians to “do good and do
    no harm”. Modern definitions of public health and bioethics
    emerged from lessons learned from the horrors of eugenics
    and genocide in the twentieth century with humanistic pre-
    cepts of “Universal Human Rights” and “Health for All” in
    the recent era (see Chapters 1 and 2).

    The law is both permissive and restrictive. It sets the basic
    responsibilities, powers, and limitations of public health prac-
    tice, with legislation and court decisions. Innovations in the
    technology of medical care and public health are powerful
    forces contributing to increased longevity, quality of life, and
    economic growth, but they also bring challenges to imple-
    mentation impeded by additional costs of the health system
    and slow adaptation in countries with the greatest need.
    These are challenges to national and international political,

    The New Public Health

    organizational, and economic systems to address health with
    the full potential for saving lives. Determining standards of
    “good practice” is a continuing process with the rapid devel-
    opment of new knowledge, technology, and experience.

    The law is a dynamic process involving old and new
    legislation, court decisions, and new issues not previously
    faced, often following rather than anticipating public health
    issues. Public health has had both positive and negative ethi-
    cal experiences and continues to face new issues with chang-
    ing population needs, technology, science, and economics.

    vaccination by Jenner (1796), to the dramatic innovations of
    the end of the twentieth century (Table 15.1). The pace of
    innovation is rapid, creating the need for regulation, quality
    control, and technology assessment.

    National governments are responsible for assuring that
    pharmaceuticals, biological products, food, and the environ-
    ment are regulated to protect the public. In some countries,
    these responsibilities are divided among ministries of trade,
    industry, commerce, health, and environment. In a federal
    system of government, there may be a division of responsi-
    bility among federal, state, and local government, but with
    the national government often providing national standards
    and leadership in this area.

    Government regulation and control are meant to protect
    the public health. The US Food and Drug Administration
    (FDA) is responsible for enforcing the Food, Drug and Cos-
    metic Act, the Fair Packaging and Labeling Act, sections of
    the Public Health Services Act relating to biological prod-
    ucts for control of communicable diseases, and the Radiation
    Control for Health and Safety Act. The FDA is a Division
    of the Department of Health and Human Services (DHHS).
    State governments have the authority to supervise pharma-
    cies and their products, which may be marketed across dif-
    ferent states. All national governments have departments
    responsible for conducting supervision of food, drugs, and
    medical devices, often relying on international standards.

    Drugs and devices include all drugs, diagnostic prod-
    ucts, blood and its derivatives, biologicals, veterinary
    medicines, and medicated premixed animal products. All
    manufacturers and distributors are required by law to reg-
    ister these products with the national authority in order to
    be allowed to market or import them. All countries need to
    govern the food, drugs, vaccines, and cosmetics regulated
    for production, importation, marketing, and use within
    their jurisdiction. Organizations within each government
    must be responsible for assuring the consumer that foods
    are pure (unadulterated) and wholesome, safe to eat, and
    produced under sanitary conditions; that drugs and medical
    devices are safe and effective for their intended uses; that
    cosmetics are safe and made from appropriate ingredients;
    and that labeling is truthful, informative, and not deceptive.

    National authorities such as the FDA, under legisla-
    tion and regulations, govern both domestic and imported
    products. They establish and enforce standards, or adopt
    external agency standards as a “gold standard”, meaning
    that products meet high standards of safety and efficacy.
    The FDA also monitors and inspects contents manufactur-
    ing standards under good manufacturing practices (GMPs),
    which includes regular accreditation of a manufacturer’s
    facilities, staffing, planning, and monitoring capacity. Test-
    ing of products is carried out to assess safety, potency, and
    toxicity using accepted reference laboratory procedures as
    published in the compendium Official Methods of Analysis
    of the Association of Official Analytical Chemists.

    When federal, state, or local investigators, sometimes
    known as consumer safety officers, detect through labora-
    tory monitoring or observe conditions that may result in a
    public health hazard, and violation of food and drug laws
    and regulations, they issue a written report to the manufac-
    turers with recommendations for correcting the conditions.
    In more blatant cases, the authorities may issue urgent recall
    or seizure orders for products in violation of standards con-
    stituting a danger to public health, such as contaminated
    products, lead-painted children’s toys, or contaminated
    foods causing foodborne disease outbreaks, which occur
    not infrequently in imported and domestically produced
    foods in the USA. The Los Angeles County Department of
    Health inspects restaurants regularly and places a promi-
    nent placard in the window giving a grade A, B, or C to
    the restaurant for sanitation and safety. Those given D rat-
    ings may be closed until specified faults are eliminated, or
    a restaurant may be closed permanently. State governments
    require restaurants to list calorie and salt content of foods
    on their menus as part of the public health efforts to reduce
    obesity.

    Supervision of food standards may also fail, as occurred
    in Israel in 2004 when total absence of vitamin B1 in a soy-
    based baby formula imported from Germany resulted in
    three deaths and permanent brain damage to other infants
    due to severe beriberi. This episode led to criminal charges
    in 2008 of negligence resulting in death against the own-
    ers of the company that imported or produced the foods and
    staff members of the Ministry of Health. Animal foods in
    2007 and infant milk products imported from China in 2008
    were found to be contaminated with melamine, which was
    meant to mimic protein content but was toxic in combination
    with other chemicals used. The infant formula caused seri-
    ous illness in some 300,000 Chinese babies and six deaths.

    The FDA and its counterparts in each country are
    responsible for regulation of:

    l food – foodborne illness, nutritional content, labeling,
    dietary supplements

    l drugs – prescription drugs and generics, over-the-counter
    products

    l medical devices – pacemakers, stents, contact lenses,
    hearing aids

    l biologics – vaccines, blood products
    l animal feed and drugs – for livestock, pets
    l cosmetics – safety, labeling
    l radiation-emitting products – cell phones, lasers, micro-

    waves
    l combination products.

    New drugs and biological products for human use are
    required to pass rigorous review before approval for mar-
    keting is granted. Applications are submitted by the manu-
    facturer or sponsor with acceptable scientific data including
    test results to evaluate the safety and effectiveness of the

    774

    product for the conditions under which it is being offered.
    All manufacturers of drugs are required to be registered
    with the FDA and to meet its requirements for each drug
    produced and marketed, including the reporting of adverse
    reactions and labeling criteria. Manufacturers are required
    to operate in conformity with current GMPs, which include
    stringent control over manufacturing processes, personnel
    training, computerized operations, and testing of finished
    products. The FDA publishes guidelines to help manufac-
    turers to familiarize themselves with current standards. The
    United States Pharmacopoeia, National Formulary, and
    WHO Model Formulary 2008 are the official listings of
    approved products.

    Medical devices are also regulated by the FDA. Thou-
    sands of products for health care purposes require premarket
    approval, ranging from basic articles such as thermometers,
    tongue depressors, and intrauterine devices (IUDs), to more
    complex devices such as cardiac monitors, pacemakers,
    breast implants, and kidney dialysis machines. These prod-
    ucts are subject to controls of GMPs, labeling, registration
    of the manufacturer, and performance standards.

    Monitoring for efficacy and potential hazards has
    been strengthened since the 1970s as a result of find-
    ings of long-term carcinogenic and mutagenic effects of
    estrogens, and toxic effects of chloramphenicol on bone
    marrow. The drug thalidomide, widely used as an antin-
    auseant and sleeping pill for pregnant women in Europe,
    Canada, and Australia in the 1960s, was not approved by
    the US FDA. This drug was found to cause large numbers
    of serious birth deformities leading to its being banned in
    most countries. Controls of blood and blood products have
    been strengthened since the transmission of human immu-
    nodeficiency virus (HIV), hepatitis B, and hepatitis C by
    contaminated blood products in the 1980s. The responsi-
    bility of this regulatory function is well illustrated by the
    1995 criminal conviction of several senior health officials
    in France for failing to stop the use of blood products con-
    taminated with HIV in the mid-1980s. Concern regarding
    possible carcinogenic effects of silicone breast implants
    led to legal action and greater controls of all implantable
    products. A balance between safety and well-regulated
    approval of new products requires a highly professional
    and motivated regulatory agency, well-developed proce-
    dures, and well-trained staff.

    The concepts of standardization of GMPs for pharma-
    ceutical products and written protocols for good medi-
    cal practice or good public health practice are accepted
    norms based on best available evidence of current scientific
    knowledge and experience. Recommended immunization
    schedules, water quality, ambient air standards, food fortifi-
    cation, and screening programs for early stages of diabetes
    are examples of accepted practice that have become rec-
    ommended standards of public health practice, paralleling
    qualitative measures developed in clinical care.

    The New Public Health

    APPROPRIATE HEALTH TECHNOLOGY

    The concept of intermediate technology pioneered by Dr
    Ernst Schumacher in the 1960s proposed the development
    of simple and inexpensive technology for developing coun-
    tries such as India to promote local economic development.
    Environmentally sustainable development and sources of
    energy, energy conservation, and reductions in toxic and
    harmful emissions are encouraged. In recent years ideas
    have included small loan systems for rural entrepreneurs in
    developing countries, and the use of simple cell phones for
    communication, farm produce marketing, cash transfers in
    remote areas without banking services, and many others.
    Now called appropriate technology, this topic has gained
    adherence in the health field in the search for low-cost and
    simple techniques for preventing and managing common
    illnesses.

    Appropriate technology is defined by the World Health
    Organization (WHO) as the level of medical technology
    needed to improve health conditions in keeping with the
    epidemiological, demographic, and financial situation of
    each country. All countries have limited resources and
    so must select strategies of health care and appropriate
    technology to use those resources effectively to achieve
    health benefits. Improved water pumps, solar energy, rain-
    water collection and water reservoirs, sanitary latrines,
    fly traps, insecticide-impregnated bed nets, biogas from
    animal waste, improved home cooking stoves, and many
    other simple devices can make enormous differences in
    local sustainable agriculture, economic growth, and living
    conditions. Cell phones are now used to monitor health
    conditions such as hypertension, diabetes control, weight
    and body mass index, and other non-communicable con-
    ditions, and to transmit imaging from remote areas to
    specialists in medical centers who can provide test read-
    ings online. Simple, affordable, portable information tech-
    nology can effectively support public health programs,
    even in resource-poor environments.

    The topics discussed in the growing literature and meet-
    ings of the International Society of Technology Assessment
    in Health Care represent the dynamic field of technology
    assessment. The issues range from economic evaluation
    of pharmaceuticals to modeling approaches, measures of
    quality of life, technology dissemination and impact, and
    outcomes measurement. The range of issues also includes
    finance and health insurance, health care in developing
    countries, informatics, telemedicine, technologies for the
    disabled, screening, and cost-effectiveness. Evaluations
    in the scrutiny of both high- and low-technology services
    based on a combination of clinical, epidemiological, and
    economic factors are necessary. As health costs rise, dis-
    abling conditions increase and populations age, medical
    innovation proceeds at a rapid rate, and both client and
    community expectations in health care continually rise.

    Chapter 15 Health Technology, Quality, Law, and Ethics

    In developing countries, the training and supervision of
    traditional birth attendants (TBAs) for prenatal preparation
    and normal deliveries are important ways to reduce maternal
    mortality in rural areas, as discussed elsewhere, and an impor-
    tant Millennium Development Goal (MDG) which will not
    be met by 2015. Community health workers (CHWs) in well
    supervised and supported programs are essential to provide
    preventive care to underserved rural poor populations with a
    defined package of services that can be tailored to meet spe-
    cific local needs, such as immunization, child growth moni-
    toring, nutrition counseling, and malaria and TB control.

    A major example of appropriate technology has
    been the WHO initiatives to promote national drug for-
    mularies (NDFs) as a consensus list of essential drugs
    that are sufficient for the major health needs of a coun-
    try, eliminating unnecessary duplication and combined
    products on the commercial market. The WHO calls on
    all member states to ensure the availability and rational
    use of drugs and vaccines, and supports states wishing
    to select an essential list of drugs for economic procure-
    ment. Assistance with drug regulatory agencies, legisla-
    tion, quality control, information, supply, and training is
    offered to help the member countries. Standard reference
    laboratories, the International Pharmacopoeia, and the
    WHO Drug Bulletin promote international standards and
    provide guidance to member states. The WHO Model List
    of Essential Drugs is a valuable tool to improve quality
    and cost management in national health systems.

    Cochlear implants are now routinely used for chil-
    dren with congenital or other loss of hearing, as well as in
    elderly people. In August 2013, a new cell phone applica-
    tion was announced which photographs the eye and can be
    used to diagnose cataracts, macular degeneration (AMD),
    and other eye pathology, for interpretation by experts far
    away and to enable arrangements to be made for appropri-
    ate intervention to prevent blindness, which is common in
    developing countries. Other applications allow for moni-
    toring of blood sugar of diabetics, hypertension, exercise,
    dietary management, and other aspects of health. In the
    same month, a camera, computer, and auditory device
    allowing blind people to “see and read” was demonstrated.
    The costs of such devices are initially high but will fall with
    advances in computing and other technical developments.

    In both developing and industrialized countries major
    causes of death include cardiovascular diseases (coronary
    heart disease and stroke), along with respiratory diseases,
    cancer and injuries, all amenable to preventive and cura-
    tive medical care. The key preventive measures for these
    are: healthful diet, reduced obesity, smoking cessation,
    exercise and physical fitness, hypertension management,
    aspirin, immunizations and other low-cost and highly effec-
    tive medications such as statins. These are all low-cost self-
    care measures that can be promoted by local, state, and
    national governments, private advocacy organizations, and

    775

    individuals in their families and communities. The princi-
    ples of low technology, cost-effectiveness, and sound health
    policy converge in addressing these fundamental issues.

    Priority Interventions in Low- and Medium-
    Income Countries

    Disease control priorities for low- and medium-income coun-
    tries are an important challenge for public health. Selection has
    often been based on individual initiatives due to strong advo-
    cacy in international organizations by donor countries, orga-
    nizations, or individuals. In 1993, two landmark documents
    attempted to apply a logical system to such considerations:
    one was the World Bank’s now classic World Development
    Report: Investing in Health and the other was Disease Control
    Priorities in Developing Countries. The World Development
    Report defined cost-effective clinical and public health cluster
    programs essential to improving health outcomes for low- and
    middle-income developing countries. The programs focus on
    those diseases that contribute heavily to the burden of disease
    and are amenable to relatively inexpensive interventions. The
    report defined interventions most able to reduce the burden
    of disease in low- and middle-income countries using clinical
    and public health interventions, as summarized in Table 15.2.

    The 1993 World Development Report provided policy
    makers and public health practitioners with a concept
    and tools for assessing cost-effectiveness of available
    interventions for the major health problems in the devel-
    oping world. It also provided useful measuring tools in
    the form of disability-adjusted life years (DALYs) to
    calculate the burden of disease and the cost-effective-
    ness of interventions to address them. This World Bank
    report addressed clinical interventions that would reduce
    DALYs lost by 24 percent in low-income countries and
    8 percent in middle-income countries, including treat-
    ment of TB, with directly observed therapy, short course
    (DOTS); integrated management of the sick child; pre-
    natal and delivery care; family planning; treatment of
    STIs; and limited care for pain, infections, and trauma
    as resources permit. It also addressed public health inter-
    ventions, which would reduce DALYs lost by 8.2 percent
    in low-income countries and 4 percent in middle-income
    countries, expanded immunization with vitamin A sup-
    plements; tobacco and alcohol control; AIDS prevention;
    and school health including deworming. Together, the
    total reductions would be 32 percent for low-income and
    12 percent for middle-income countries (Table 15.2).

    These estimates have been refined by numerous stud-
    ies conducted over the subsequent two decades. The sec-
    ond edition of the Disease Control Priorities in Developing
    Countries (2006) incorporates important changes in the
    technologies available. The concept of viewing priorities
    with an economic epidemiology model is still applicable,
    and has increased in importance (Box 15.1).

    776

    As the MDGs are reaching their endpoint in 2015,
    follow-up global health targets will need to recognize the
    vital importance of non-communicable diseases (NCDs)
    in developing countries. The global consensus on MDGs,
    set out by the United Nations (UN) in 2001, indicates
    progress in the epidemiological understanding of realities

    The New Public Health

    in low-income countries and the need for consensus over
    common targets. Since then, attention has been directed
    towards the epidemiological shift to NCDs, which are the
    most common causes of death in low- and medium-income
    countries. Thus there is a double burden of infectious, nutri-
    tion, maternal, and child priorities, alongside the NCDs.
    The increasing adoption of vaccines such as Haemophilus
    influenzae type b (Hib) and rotavirus alongside the standard

    BOX 15.1 Disease Control Priorities in Developing
    Countries

    l Average life expectancy in low- and middle-income
    countries increased dramatically since the 1960s, while
    cross-country health inequalities decreased.

    l Improved health has contributed significantly to eco-
    nomic welfare since the 1960s.

    l Five critical challenges face developing countries (and
    the world) at the beginning of the twenty-first century:
    – Rapid demographic growth
    – HIV pandemic improved but still rampant
    – Persistent malaria, TB, diarrhea, pneumonia
    – Micronutrient malnutrition for mothers and infants
    – NCDs
    – Possible pandemics.

    l Cost-effective interventions include:
    – Interventions to reduce neonatal mortality (50 per-

    cent of total child deaths)
    – Treatment of HIV-positive mothers, treatment of sex-

    ually transmitted infections
    – Controlling tobacco use, particularly through

    taxation
    – Lifelong medical management of risk factors in indi-

    viduals at high risk for heart attacks or strokes, using
    aspirin and other drugs, would benefit tens of millions
    of individuals.

    l Reform of health services and systems is needed,
    including:
    – Provider incentives
    – Provider focus on selected intervention to gain

    experience
    – Strengthening surgical capacity at district hospitals
    – Targeting limited resources to diseases affecting the

    poor, e.g., TB in low-income countries
    – In middle-income countries, public finance (or pub-

    licly mandated finance) of a substantial package of
    clinical care for all.

    l Generation and diffusion of new knowledge and prod-
    ucts underpinned the enormous improvements in health
    in the twentieth century and need to be applied for the
    control of NCDs, HIV, TB, and neglected populations.

    NCD = non-communicable disease.

    Chapter 15 Health Technology, Quality, Law, and Ethics

    diphtheria–pertussis–tetanus (DPT), poliomyelitis (polio),
    and measles–mumps–rubella (MMR) vaccines provides
    new possibilities to control the major infectious disease
    killers of children. New technologies such as the advent of
    antiretroviral treatment for HIV have led to startlingly suc-
    cessful improvements in the quality of life and longevity of
    HIV/AIDS patients, and the prevention of onward transmis-
    sion of HIV from mothers to babies and sexual partners.
    The WHO and many other global health stakeholders con-
    tinue this work and produce analyses to contribute to policy
    making based on economic epidemiological evidence. This
    work affects policy, slowly but importantly.

    In 2003, the Bellagio Study Group on Child Survival
    estimated that the lives of 6 million children could be saved
    each year if 23 proven interventions were universally avail-
    able in the 42 countries in which 90 percent of child deaths
    occurred in 2000. The MDGs set out in 2001 provided tar-
    gets for economic, educational, and environmental improve-
    ments, with three specifically focused on health: reducing
    child mortality; reducing maternal mortality; and control of
    HIV, TB, and other diseases. While important progress is
    being made, some of these targets will not be achieved by
    2015. The global public health infrastructure will need to be
    expanded in content and strengthened in order to implement
    lessons learned in childhood routine immunization, safe
    maternity care, and nutritional security (see Chapter 16).

    In medium- and low-income countries the difficulties are
    much more severe because of limited resources for health and
    the weak infrastructure of facilities and human resources in
    many countries. The key issues relate to NCDs, as in developed
    countries, so the interventions most needed address cardiovas-
    cular diseases, cancer, and injury, as well as diarrheal diseases,
    malnutrition, vaccine-preventable diseases, HIV, TB, malaria,
    and neglected tropical diseases. Efforts should be focused on
    low-cost interventions such as smoking reduction, vitamin and
    mineral fortification of foods, HIV, TB, and malaria control,
    along with maternal and child health protection.

    Priority Selection in High-Income Countries

    As discussed in Chapters 5 and 13, high- and middle-income
    countries also face complex health challenges, including
    aging populations, health costs, rapid development of new
    drugs and technologies, high rates of NCDs, and the rising
    prevalence of obesity and diabetes. Selection of priorities
    for health care expenditure from public and private sources
    has become a major focus of managing health systems.

    In the industrialized countries, technological advances in
    the medical and public health fields have been major contribu-
    tors to increasing longevity but also rising health costs. This
    situation has led to pressures for greater selectivity in adopting
    costly innovations without adequate assessment of benefits
    and costs. Many countries have adopted more cautious poli-
    cies with regard to financing high levels of expansion of new

    777

    technology in the field of medical equipment, clinical proce-
    dures, or medications. Organized assessment of technology is
    now an essential feature of health management at the interna-
    tional, national, and local levels of service delivery. The major
    responsibility for technology assessment is at the national
    level, even with decentralization of service management.

    With available resources being limited, health systems
    must choose interventions to be selected and how health
    systems are to be organized for efficiency and effectiveness
    while meeting public expectations. The US Patient Protec-
    tion and Affordable Care Act (PPACA, more generally called
    ACA or “Obamacare”) is undertaking reform measures to
    promote efficiency and prevention to reduce per capita health
    costs and to include more people in prepaid health care (see
    Chapters 10 and 13). These include preventive measures as
    recommended by Healthy People 2020 and implementation
    committees for selection of cost-effective measures to reduce
    morbidity and mortality to reduce health costs. The range
    of services to be promoted includes smoking cessation,
    increased physical activity, weight loss, healthy dietary prac-
    tices, cancer screening, and many others that have not been
    previously accessible to those living in poverty and with no
    or limited health insurance. There is an emphasis on vaccina-
    tion for children and adults.

    The WHO promotes the widespread use of basic radio-
    logical units (BRUs) to increase access to low-cost, effective,
    diagnostic X-rays, especially in rural areas in developing
    countries. BRUs are hardy, relatively inexpensive pieces of
    radiological examination equipment that can be used in harsh
    field conditions for simple diagnosis of fractures and respi-
    ratory infections. The WHO estimates that 80 percent of all
    diagnostic radiology can be performed adequately using sim-
    ple, safe, and low-cost equipment, supported by training of
    local people to operate and maintain the equipment. This is a
    consensus view of leading radiologists and clinicians helping
    the WHO to develop model equipment and training material.

    The WHO World Health Report of 2009 focused on
    health technology assessment, stating:

    “Technology continues to transform the medical care system and
    to improve length and quality of life – but at substantial cost. It
    is almost inconceivable to think about providing health care in
    today’s world without medical devices, machinery, tests, computers,
    prosthetics, or drugs. Medical technology can be defined as the
    application of science to develop solutions to health problems or
    issues such as the prevention or delay of onset of diseases or the
    promotion and monitoring of good health.”

    Appropriate technology in the health field is becoming
    increasingly complex, laden with economic, legal, and ethi-
    cal issues. Professional and public opinion demands make
    this a highly sensitive area of health policy, but responsible
    management of resources requires decision making that
    includes consideration of the effectiveness, costs, and alter-
    natives of any new technology (Box 15.2). Failure to adopt

    778

    new innovations can result in obsolescence, while excessive
    expenditures for hospitals and medical technology prevent
    a health system from developing more cost-effective pre-
    ventive approaches, such as improved ambulatory care, or
    supportive care for the chronically ill.

    HEALTH TECHNOLOGY ASSESSMENT

    Technology adoption can be a highly emotional and con-
    troversial issue, in advocacy of new cancer treatments or in
    criticism of managed care or national regulatory agencies,
    but spending limited national resources on some devices
    or medications of unproven value or inappropriately long
    hospital stays denies resources needed for other aspects of
    health care. A society must be able and willing to pay for
    medical innovation or improving quality of life by medical
    and public health interventions. Underfunding of a health
    system can deny these benefits just as misallocation of
    resources does, and this is a political issue even more than
    a professional one.

    Medical and health technology assessment is the pro-
    cess of determining the contribution of any form of care
    to the health of the individual and community. It is a sys-
    tematic analysis of the anticipated impact of a particular

    BOX 15.2 Health Technology Assessment

    Questions that form the basis of technology assessment for a
    medical innovation include the following:
    l Is it safe and cost-effective for the stated purpose?
    l Is it a new service, or does it replace a less efficient inter-

    vention which can be phased out of service?
    l What is the need it addresses?
    l Where is it in the order of priorities of development of

    the facility?
    l Does it duplicate a service already available in the

    community?
    l Does it make medical sense (i.e., does it help in diagnosis

    and treatment for the patient’s benefit)?
    l What are the alternatives?
    l What are the resources needed in terms of supplies, staffing,

    and upkeep?
    l Can the facility afford it?
    l What could otherwise be done with the resources it

    requires?

    The New Public Health

    technology in regard to its safety and efficacy as well as its
    social, political, economic, legal, and ethical consequences.
    The technology may be a machine, a vaccine, an opera-
    tion, or a form of organization and management of services.
    Analysis should include cost–benefit and cost-effectiveness
    studies (see Chapter 11) as well as clinical outcomes and
    other performance indicators.

    Pressures from medical professionals, manufacturers of
    new medical equipment, and the public for adoption of new
    methods can be intense and continuous. Care must be taken
    that the specialists involved in committees for assessment
    are not those who may directly or indirectly benefit from
    the exploitation of technology, and who therefore may have
    conflicts of interest. Assessment must be multidisciplinary,
    involving policy analysts, physicians, public health special-
    ists, economists, epidemiologists, sociologists, lawyers,
    and ethicists. The available information needs to include
    evidence from clinical trials, critical analysis of the litera-
    ture, and the economic effect of adopting the technology on
    allocation of resources.

    Medical technology varies in complexity and cost, not
    only to produce but in its utilization. Medical technology
    that is inexpensive to supply and administer is known as
    low technology or low-tech, while high technology or high-
    tech refers to costly and complex diagnostic and treatment
    devices or procedures.

    At the low-tech end of the technology scale, oral rehy-
    dration therapy (ORT) was developed in the 1960s for oral
    replacement of fluids and electrolytes lost in diarrheal dis-
    ease, particularly in children. It has been described as one
    of the greatest medical breakthroughs of the twentieth cen-
    tury. The introduction and wide-scale use of ORT for pre-
    vention of dehydration from diarrheal diseases throughout
    the world has saved hundreds of thousands of lives. Use
    of insecticide impregnated bed nets and reintroduction of
    DDT in household spraying along with vector control and
    improving diagnostic tools are low-tech but effective and
    key tools in malaria control.

    Advances in endoscopic surgical techniques since the
    1990s, and in robotic surgery since 2000, have greatly
    improved patient care by reducing trauma, discomfort, and
    length of hospital stay and endoscopy has become the surgi-
    cal approach of choice for many procedures. Since reports
    of the first 100 operations performed in France in 1990,
    endoscopy has spread rapidly to all parts of the world. It is
    now recognized by surgeons worldwide as a safer, less trau-
    matic and more effective alternative to traditional invasive
    surgery. Although the operating time is longer, patients are
    discharged from the hospital within several days and return
    to work shortly thereafter, compared to the long hospital
    stays after more invasive surgical procedures in the past.
    Following traditional abdominal surgery, a patient may
    acquire infections and require intensive care initially and a
    recovery period of many weeks.

    Chapter 15 Health Technology, Quality, Law, and Ethics

    Endoscopic surgery for cholecystectomy and esopha-
    geal, colorectal, hernia repair, renal, orthopedic, and other
    forms of surgery which previously were carried out with the
    patient remaining in hospital for many days are now done
    on a not-for-admission basis. Not-for-admission surgery has
    become standard practice in hospitals, extending the range
    of outpatient surgery and the comfort of patients who can
    return to their own homes to recuperate and return to regu-
    lar activities much sooner. Fewer complications arise and
    patient comfort and economic implications are important.
    As a result, fewer hospital beds are needed for postoperative
    care than previously thought necessary, while surgical and
    ambulatory care facilities may need expansion to accommo-
    date the growing elderly populations needing surgical inter-
    ventions but requiring shorter recovery. This innovation is
    now accepted as the standard of much of modern surgical
    care and shows that simple organizational changes can save
    money and improve patient safety and comfort.

    The bacterium Helicobacter pylori was first identified
    as the cause of peptic ulcers of the stomach and duodenum
    in 1982 (Robin Warren and Barry Marshall, Nobel Prize
    2005). This discovery led to effective diagnosis and rapid,
    inexpensive treatment of chronic peptic ulcer disease. This
    has resulted in elimination of a major component of surgi-
    cal procedures for chronic peptic ulcer diseases as well as a
    reduction in gastric cancer (see Chapter 4). Surgery for gas-
    trectomies, vagotomies, and other outdated forms of treat-
    ment are now virtually gone, contributing to a decreased
    need for hospital beds even for an aging population. This
    and many other innovations in medical care have led to a
    growth in the use of ambulatory care for many forms of
    surgical, medical, and mental health care, along with much
    shorter length of hospital stay than in previous times. All of
    these factors have led to greater emphasis on ambulatory,
    outpatient, and home care services.

    The dissonance between high-tech and low-tech proce-
    dures may lead to serious consequences in any health system.
    Choices require well-informed analysis of benefits, costs,
    alternatives, ethical considerations, and political consequences
    before limited health care resources are allocated between
    hospital-based high-tech medicine and low-tech primary care.

    High-tech procedures are usually applied in hospital
    settings in the context of other highly specialized care for
    seriously ill, often terminal, patients. Computed tomogra-
    phy (CT), invented in the 1960s, quickly proved to be an
    extremely valuable diagnostic tool. Advances in CT, mag-
    netic resonance imaging (MRI), and subsequent imaging
    techniques have proven to be cost-effective and lifesaving,
    replacing less efficient and more dangerous invasive proce-
    dures. The CT and MRI scans allow the clinician to reach a
    rapid diagnosis of many lesions before they can be detected
    by other invasive and dangerous diagnostic techniques, at
    stages where the lesions are subject to earlier and more
    effective interventions. Imaging technology is advancing

    779

    rapidly and promising inexpensive new systems for long-
    distance transmission of imaging to medical centers may
    provide enormous benefits to people living in rural or
    developing countries. Recent advances in low-intensity CT
    screening of long-term heavy smokers for lung cancer have
    recently been added to recommended and potentially effec-
    tive and cost-saving practice and may change the outlook
    for this disease in the coming decade (US Preventive Ser-
    vices Task Force, 2012 Flahault and Martin Moreno, 2013).

    Technology assessment also examines methods of pre-
    venting and managing medical conditions. Treatment proto-
    cols or clinical guidelines are based on decision analysis of
    accumulated weight of evidence. Published clinical studies
    are assessed in meta-analyses, using statistical methods to
    combine the results of independent studies, where the stud-
    ies selected meet predetermined criteria of quality. This pro-
    vides an overview from pooling of data, but also implies an
    evaluation of the studies and data used. Clinical guidelines
    are part of raising standards of care, but also contribute to
    cost containment. Many countries form professional study
    groups to carry out meta-analyses on important health pol-
    icy issues and new technologies.

    Technology Assessment in Hospitals

    There is considerable variance among countries, hospitals
    consume between 40 and 70 percent of total national health
    expenditures, with pressures for increased staffing and
    novel medical technology being a continual inflationary
    factor. Industrialized countries have all reduced their acute
    care hospital bed supplies and length of stay so that their
    expenditures for hospital care have fallen to between 30-40
    percent of total health expenditures. Shorter stays and older
    patients have resulted in a drift towards intensive care, espe-
    cially for internal medicine patients. Medical innovation is
    a continuing process with new diagnostic and treatment
    modalities reaching the market.

    Hospitals no longer live in splendid isolation in the
    medical economy. A national or state government needs
    regulatory procedures to rationalize distribution of medical
    technology. The “certificate of need” is a form of technology
    assessment that has been used in the USA since the 1960s
    to assess and regulate the development of hospital services
    to prevent oversupply and costly duplication of services. It
    attempts to establish and implement the use of rational crite-
    ria for diffusion of expensive new technology. Whether this
    has had a lasting impact on restraining the excesses of high-
    tech medicine is arguable. This regulatory approach was
    limited to the hospital setting and failed to stop the develop-
    ment of high-tech medical services such as ambulatory for-
    profit CT, imaging, and in vitro fertilization centers.

    Many countries have adopted national technology
    assessment systems to review topics as far-ranging as
    guidelines for acute cardiac interventions; liver, heart, and

    7

    80

    lung transplantation; minimal access surgery; and beam and
    isotope radiotherapy. Other technology assessment guide-
    lines include diagnostic ultrasound, sleep apnea, molecu-
    lar biology, prostate cancer, MRI, and new medications for
    inclusion in a national health system’s approved basket of
    services.

    Despite the limitations of this approach, where govern-
    ments do not directly operate health care services, gov-
    ernmental regulation is necessary to prevent inequities in
    services by excessive development in some geographic
    areas at the expense of others, or by overexpansion of the
    institutional sector of health care at the expense of primary
    care. Regulatory mechanisms are essential in health care
    planning to restrain excessive and inappropriate use of
    high-tech services, but need augmentation by fiscal incen-
    tives to promote other essential services.

    Hospitals everywhere face serious problems of hospital-
    acquired infections, which occur in about 5 percent of all
    hospitalizations. Healthcare-associated infections (HAIs),
    including multidrug-resistant bacterial infections, cause
    long lengths of stay, high costs, and most importantly, unex-
    pected deaths and serious disabilities. Prevention of hospital-
    acquired infection requires ongoing training, staffing, and
    organization. The Centers for Disease Control and Prevention
    (CDC) defines HAIs as “infections caused by a wide variety
    of common and unusual bacteria, fungi, and viruses during
    the course of receiving medical care”. Some of the preventive
    measures are simply promoting frequent hand washing by
    caregivers and visitors, and immunization of staff members
    against influenza and pneumonia, which can be problematic
    if there is staff resistance to influenza vaccination.

    Training and routine supervision of cleaning staff are
    also vital, as are strict infection control measures for isola-
    tion rooms, strict protocols for catheter care, surgical suite
    sterility, surgical site infections, central line associated
    bloodstream infections, ventilator-associated pneumonias,
    catheter-associated urinary tract infections, and Clostridium
    difficile-associated disease. Guidelines for their control in
    surgical dialysis, pediatric, outpatient, and other vulnerable
    departments are available from CDC. The benefits of pre-
    ventive procedures for this problem include cost estimates
    ranging from US$5.7–6.8 billion (20 percent of infections
    preventable) to US$25.0–31.5 billion, yet 70 percent of HAIs
    are preventable by well-known methods such as frequent and
    careful hand washing by medical and nursing staff, catheter
    and infusion care, and other similar measures (CDC, 2012).

    Technology Assessment in Prevention and
    Health Promotion

    Technology assessment of preventive care programs
    includes evaluation of the methodology itself, along with
    the costs and measurable benefits, as in reduced burden

    The New Public Health

    of disease. DOTS is the standard management of sputum-
    positive and sputum-negative TB, at low cost for DALYs
    saved. The coexistence of HIV and other complications
    has created multidrug-resistant tuberculosis (MDR-
    TB), which is difficult and costly to treat and cases
    constitute a source of continuing spread of the disease.
    A 2012 meta-analysis of cost-effectiveness of MDR-TB
    treatment in Estonia, Peru, the Philippines, and Russia
    shows it to be cost-effective and best carried out on an
    ambulatory basis (Fitzpatrick and Floyd, 2012).

    Wide use of available and effective vaccines such as
    Hemophilus influenza b (Hib), pneumococcal pneumo-
    nia, influenza and rotavirus reduce hospitalizations and
    mortality from respiratory and diarrhoeal diseases among
    children, the elderly and other age groups. Vaccine prices
    generally fall after their initial period of use as manu-
    facturing costs are lessened by improved methods or by
    bulk purchase contracts, as occurs in the public sector. For
    example, in 2012 MMR vaccine cost US$19.33 per dose if
    purchased through the CDC, but US$52.73 per dose if pur-
    chased in the private sector in 10 packs of single-dose units
    of the vaccine. A combined diphtheria, tetanus, acellular
    pertussis (DTaP) vaccine cost US$15.00 when purchased
    through CDC, while the same vaccine purchased with hep-
    atitis B and inactivated polio vaccine (IPV) cost US$52.10 per
    dose. But the combination saves repeated visits and loss
    of compliance for that reason. The new human papilloma-
    virus (HPV) cervical cancer vaccine cost US$130.27 per
    dose for the series of three doses per person, while the vac-
    cine against diarrhea-causing rotavirus, approved in 2006,
    cost US$106.57 per dose for the recommended three doses
    (CDC, 2012).

    The WHO recommends the inclusion of rotavirus vac-
    cination in a country’s immunization program, but the costs
    of the current generations of rotavirus vaccines are high in
    comparison to the budgets for vaccines for prevention of
    childhood illnesses in many developing countries. Many
    cost-effectiveness studies have shown this vaccine to be
    highly beneficial and it could help to reduce the very high
    global burden of disease of over 500,000 child deaths and 2
    million hospitalizations occurring annually (Tu et al., 2011).

    Vaccine programs must take into account transportation
    and administrative costs and expenses of ordering, storing,
    inventory control, cold chain, insurance, wastage, and spoil-
    age. Multiple vaccines in one dose are less costly and less
    inconvenient for all. Examples include DTaP plus polio and
    Hib, or MMR (see Chapters 4 and 6). There is a need for
    implementation of legal protection of manufacturers from
    excessive litigation judgments while protecting the interests
    of the public and individuals who may have reactions to
    vaccines.

    In 2012, the reappearance of pertussis and diphthe-
    ria raised concerns about immunization coverage and

    Chapter 15 Health Technology, Quality, Law, and Ethics

    efficacy. Public opinions on vaccination may not be as
    supportive as in previous years. Mothers who oppose per-
    tussis immunization for their children, such as occurred in
    the UK during the 1980’s, leave their children vulnerable
    to a serious and often deadly disease, which has recurred
    since 2010.

    The WHO estimates the cost of all immunization activi-
    ties in all 117 low- and middle-income countries for the
    period 2006–2015 to be US$75 billion, while low-income
    countries would need US$35 billion. The rate of adoption
    of currently available and new vaccines will be determined
    by governmental decisions in each country, although exter-
    nal aid – such as that of the Global Alliance for Vaccines
    and Immunization (GAVI), an international public–private
    consortium to promote vaccination – is a valuable resource.
    The United Nations Children’s Fund (UNICEF) is con-
    cerned about supply problems as well as costs, but the key
    issue relates to political decisions, funding, and capacities
    of national immunization systems.

    Despite an excellent vaccine having been available since
    the 1960s, measles epidemics continue to occur in the indus-
    trialized countries. In the 1900s global deaths from measles
    were in the order of 1 million people per annum. Two major
    epidemics of measles occurred in Canada in the early 1990s,
    despite high rates of immunization coverage. Following this, a
    1993 Delphi conference of experts from 31 countries reached
    a consensus recommending a two-dose measles immuniza-
    tion policy. Measles eradication has been set as a goal by the
    WHO and 90 percent reduction in cases and fatalities has
    been achieved since the 1990s. However, measles elimination
    requires coverage of 95 percent of children and two doses of a
    measles-containing vaccine (preferably MMR).

    Measles reappeared as a widespread disease in Europe in
    2010–2013 with tens of thousands of cases, many hospital-
    izations, and some deaths. It spread to the Americas, brought
    by travelers, and resulted in modest sized outbreaks, includ-
    ing the UK in 2012–2013. Eradicating measles by 2020 is
    projected to cost an additional discounted US$7.8 billion and
    avert a discounted 346 million DALYs between 2010 and
    2050. As new vaccines enter the field, it is important to evalu-
    ate their effectiveness, costs, and the benefits to be derived.

    The cost of the hepatitis B vaccine initially was over
    US$100 for an immunization schedule of three doses but
    has come down dramatically to less than US$1 per dose
    in developing countries for bulk purchases. However, in
    the USA, the price of vaccination per dose is estimated at
    US$41 if given by a general practitioner, US$15 if adminis-
    tered through an existing childhood immunization program,
    and US$17 if given through the school medical system.
    This is a standard vaccine covered by public and private
    health insurance systems. The vaccine is a cost-effective
    method to prevent liver cancer and the long-term effects of
    chronic hepatitis.

    Screening and education for thalassemia in high-prev-
    alence areas have nearly eradicated the clinical disease but
    not its carrier status in Cyprus, southern Greece, and other
    countries. Newborn screening and case management for
    phenylketonuria, congenital hypothyroidism, Tay–Sachs
    disease, and many other genetic diseases have been shown
    to be far less expensive than post-facto treatment of severely
    developmentally delayed and dependent children born with
    these diseases (see Chapter 6).

    The success of Papanicolaou (Pap) smear screening in
    reducing cancer of the cervix mortality since the 1960s has
    been dramatic. The discovery of causation of cancer of the
    cervix by HPV strains led to development of an effective
    vaccine, which has been in use since 2006. Recent evidence
    shows that male circumcision can reduce transmission of
    HPV as well as HIV and other sexually transmitted dis-
    eases, and it is being adopted as an effective intervention
    in countries with high rates of both HIV and cancer of the
    cervix, such as in sub-Saharan Africa.

    The drastic reduction in cancer of the cervix provides
    a powerful demonstration of the effectiveness of public
    health screening and other measures to control this major
    malignant cause of death in women. Screening for cervi-
    cal cancer by Pap smears is recommended annually for
    high-risk groups, and every 2 or 3 years for other adult
    women (Box 15.3). Screening will remain vital for many
    years to come as the HPV vaccine comes into general
    use, and as its cost is reduced, but its protective effect for
    individual and herd immunity will not replace the need
    for ongoing screening for this very common cancer. HPV
    vaccine is also being recommended for all boys to pre-
    vent oral and anogenital cancers and HPV transmission
    to girls.

    Routine mammography screening for breast cancer
    every 1–2 years is recommended by the US National Can-
    cer Institute for women over the age of 40 and for younger
    women with high-risk factors (e.g., previous cancer, fam-
    ily history, genetic markers). Cost-effectiveness analysis is
    now an essential part of decision making in health policy
    and priorities. While there is controversy over the frequency
    of routine testing, mammography remains a mainstay in
    women’s health and contributes to early case finding and
    falling mortality rates from breast cancer. Figure 15.1 dem-
    onstrates differences in utilization of mammography among
    US women in the age group 50–64 years within the previ-
    ous 2 years, by insurance status. US women with private
    insurance (mostly through place of employment) had over
    70 percent compliance, those with public insurance (pri-
    marily Medicaid) averaged about 60 percent compliance,
    while those with health insurance had average compliance
    rates of about 45 percent during the period 1993–2010.
    The UK National Health Service (NHS) invites women
    between the ages of 50 and 70 for screening every 3 years;

    Cancer of the cervix is the second most common cancer among
    women worldwide, with about 500,000 new cases and 250,000
    deaths worldwide annually. Approximately 80 percent of cases
    occur in low-income countries, where cervical cancer is the
    second commonest cancer in women (WHO, 2012).

    In the USA, and other industrialized countries, the incidence
    and mortality of cancer of the cervix have been going down
    steadily since the introduction of Papanicolaou (Pap) smear
    testing. Cervical cancer incidence declined during the period
    1999–2008 by 2.3 percent per year and mortality declined by
    1.9 percent per year an estimated 12,170 cases of invasive cer-
    vical cancer diagnosed in the USA with 4220 deaths in 2012.

    Prevention of cancer of the cervix has until recently mainly
    focused on Pap smears to detect the disease while still in a pre-
    cancerous (cancer in situ) phase, and this procedure reduced
    rates dramatically over the latter part of the twentieth century. The
    newly developed and highly effective vaccines against key strains
    of human papillomavirus (HPV) is now being used in routine
    immunization of young girls and more recently boys as well. The
    high cost of the vaccine precludes its rapid diffusion to most parts
    of the world but its use is spreading and being included in immu-
    nization programs funded by donor agencies in sub Saharan
    Africa. The vaccine should, in principle, also be used by adult
    women, in addition to continuation of routine Pap smear testing.

    In the past decade, evidence of HPV as the cause of cancer
    of the cervix and the presence of HPV in uncircumcised men has
    brought circumcision back to professional and public debate.
    Reports from Africa of reduced risk of acquiring HIV among
    circumcised men have brought new attention to adult male cir-
    cumcision, which is now actively promoted many sub-Saharan
    African countries.

    The technological breakthroughs of the Pap smear in the
    1950s, HPV testing in the 1990s, and the HPV vaccine in the
    2000s should also include prevention by male circumcision.
    Visual inspection of the cervix and cryotherapy can treat pre-
    cancerous cervical lesions in areas of developing countries
    as part of community health worker programs.

    Colorectal cancer, the 7th leading cause of death in high
    income countries, is amenable to prevention by early screening
    using colonoscopy and fecal occult blood (FOB) testing. Screening
    is recommended for all persons over age 50 at 5 year intervals
    along with annual FOB testing. Where there is a family history of
    colorectal cancer or polyps, routine screening should begin ear-
    lier. Increasing use of screening and improved medical care are
    resulting in improving survival and declining mortality rates.

    Stomach cancer is 10th leading cause of death in upper
    middle income countries. Prevention relies on early treatment
    of chronic peptic ulcer disease caused by Helicobacter pylori
    infection. This is readily diagnosed by a simple breath test and
    completely cured by low cost antibiotics. Increased awarenss
    and access to these services would enhance long term trends of
    reducing mortality from stomach cancer.

    Liver cancer is 8th leading cause of death in upper middle
    income countries due to the global prevalence of hepatitis B
    and helaptitis C. Hepatitis B is now falling due to widespread
    vaccination in childhood. Hepatitis C is now the major cause
    of liver cancer affecting hundreds of millions of persons world-
    wide. There is still no vaccine currently available, but screen-
    ing and treatment is now used in the industrialized countries
    and will become more widely used as simpler, less costly treat-
    ments with less side effects are becoming available.

    Early detection of lung cancer with spiral low dose
    tomodensitometry for smokers is recently being recommended
    by many professional bodies.

    More basic cancer preventive measures such as smoking
    cessation, healthy diets, regular exercise, and moderate alco-
    hol use are discussed in chapter 5.

    with an average of 75 percent respond to the invitation, of
    whom 4 percent are referred for further testing (UK Can-
    cer Research, 2012) and as in most industrailized countries
    breast cancer mortality rates are falling impressively (see
    Chapter 5).

    Health promotion in reducing exposure to HIV and
    cigarette smoking has been shown to be very cost-effec-
    tive despite its low-tech or non-technological meth-
    odology, involving primarily group or mass education.
    Hypertension screening and case management is low-
    tech but highly effective in preventing strokes and blind-
    ness.

    Low-tech innovations have had an important impact
    in reducing death and injury. These include mandatory
    use of car seat belts (introduced since the 1970s and
    1980s in many countries), children’s car seats, air bags,
    and bicycle and motorcycle helmets. Iodization of salt,
    vitamin A supplementation, and food fortification pre-
    vent large numbers of clinical cases of severe retarda-
    tion, death, and blindness at low cost per child protected.

    Education for reducing risk factors for the cardiovascu-
    lar disorders is far less costly than the premature deaths
    and high medical costs of patients suffering stroke and
    congestive heart failure. Health education, condom and
    needle supply, and screening of blood donations are the
    most important effective community health measures
    against the spread of HIV. Table 15.3 shows a compari-
    son of high-tech and low-tech approaches, which often
    complement each other, to selected health problems.

    Technology assessments represent the current con-
    sensus derived from reviews of published studies and
    exchange of views of highly qualified clinicians, epide-
    miologists, and economists within a context of technol-
    ogy assessment. They may change over time as new data
    or innovations are reported, and this possibility should
    be kept in mind in such discussions. Technology assess-
    ment mobilizes information and critically analyzes many
    aspects of medical technology to build a wide community
    consensus to influence policy decisions. Public opinion,
    political leadership, and administrative practice, as well
    as the scientific merit of a case are all factors in develop-
    ing a consensus.

    Technology Assessment in National Health
    Systems

    Technology assessment requires an organization within
    the framework of national regulatory agencies. The FDA
    serves this purpose as a statutory body within the US Pub-
    lic Health Service. Sweden, Canada, Australia, the UK, the
    Netherlands, Spain, and other countries also have technol-
    ogy assessment advisory or regulatory agencies established
    by national governments to monitor and examine new tech-
    nologies as they appear. Sweden has a widely representa-
    tive national Swedish Council for Technology Assessment
    in Health Care which has an advisory role to the national
    health authorities.

    The processes used in traditional systems to regulate
    food and drugs for efficacy, safety, and cost are more
    recently being applied to new medical devices and proce-
    dures. The unrestricted proliferation of new procedures
    presents serious dilemmas for national agencies con-
    cerned with financing health care and controlling cost
    increases. Non-governmental health insurance shares
    this concern, as does industry, which bears much of the

    784

    cost of health insurance through negotiated, collective
    bargaining, “voluntary” health insurance in the USA.
    Most industrialized countries have national health ser-
    vices or national health insurance and are thus vitally
    interested in health costs and technology assessment.
    Many industrialized countries maintain technology
    assessment and cost-control activities. In the USA, the
    Agency for Healthcare Research and Quality (AHRQ)
    maintains oversight and studies related to clinical infor-
    mation, including evidence-based practice, outcomes and
    effectiveness, comparative clinical effectiveness, risks
    and benefits, and preventive services.

    In Canada, the Health Protection Branch of the Federal
    Department of Health reviews medical devices and drugs
    and, with consent of the provincial governments, approves
    new medical procedures. Concern by governments over the
    cost implications of new procedures led to this practice.
    Since 1988, a network of government and professional
    bodies has formed a non-profit agency for technology
    assessment (Canadian Agency for Drugs and Technologies
    in Health, CADTH). This supports the provincial adminis-
    tration of health insurance in resisting professional, com-
    mercial, or political pressures to add untested technology
    or procedures to the health system as covered benefits. A
    comparison of rates of procedure performance between
    provinces shows very high discrepancies, as high as two-
    fold, in procedures such as coronary artery bypass graft or
    prostatectomy. Control of acquisition of high-tech equip-
    ment by national or state authorities is essential to prevent
    expenditures on high-cost equipment without adequate
    assessment.

    The New Public Health

    DISSEMINATION OF TECHNOLOGY

    The rapid spread of high-tech medical equipment has played
    a substantial role in escalating health costs. A comparison of
    the number of MRI scanners per million population in mem-
    ber countries of the Organisation for Economic Co-operation
    and Development (OECD) (Table 15.4) showed Japan and the
    USA with the highest number at 43.1 in 2010 (23.2 in 2000–
    01) and 31.6 (15.4 in 2000) per million, respectively, while
    the median was 10.5. Canada ranked fourteenth among the 20
    OECD countries with 8.2 MRI scanners per million. Compar-
    ing CT scanners showed that Japan had the highest number
    at 97.3 while the median was 15.6. Canada was in eighteenth
    place among the 28 OECD countries reporting in 2010 with
    14.2 CTs per million population. However, it should be noted
    that countries with the most machines have lower productiv-
    ity per machine. The USA has far fewer examinations per
    machine than other countries (OECD, 2012).

    The use of endoscopic surgery has spread worldwide
    since the 1990s. Health professionals become almost
    instantly aware of new developments from the news media
    as well as professional diffusion of information at confer-
    ences, in exchange visits, in published articles, and most
    dramatically via the Internet. National policy to foster the
    introduction of appropriate new technology requires a
    careful program of regulatory and financial incentives and
    disincentives to encourage or discourage diffusion of new
    methods of prevention as well as of treatment and com-
    munity health care. Kidney transplantation has become a
    cost-effective and patient-friendly alternative to long-term
    dialysis both in hospital and at home. The key limitation is

    the shortage of donors. The same can be said for liver trans-
    plantation, which has also been shown to be cost-effective
    in terms of DALYs saved from chronic liver diseases such
    as cirrhosis and hepatitis B and C. Heart transplantation has
    spread among major centers in western countries.

    The black market in organs for transplantation has
    become an international scandal of exploitation of poor
    people in low-income countries, and is the subject of police
    investigation in many countries, but it is difficult to control.

    Bone marrow transplantation is now used widely and
    is effective in saving the lives of many people with malig-
    nant and non-malignant hematological disorders. Stem cell
    therapy, by introducing new adult and embryonic stem cells
    into damaged tissue to treat disease or injury, is becoming
    feasible for a wide variety of conditions including cancer,
    type 1 diabetes mellitus, Parkinson’s disease, Huntington’s
    disease, celiac disease, cardiac failure, muscle damage, and
    neurological disorders.

    Limitation of new techniques or procedures to selected
    medical centers allows the passage of time to fully assess
    the merits and deficiencies of new technology before gen-
    eral diffusion into the health care system. Such limitation,
    however, is fraught with the danger of depriving the popu-
    lation of benefits of new medical technology, and the pos-
    sibility of restraint of trade to the economic advantage of
    selected providers. Current advances in robotic-assisted sur-
    gery will expand during the coming decade for brain, bone,
    joint, prostate, and other surgery, and need to be assessed
    with regard to patient care benefits, costs, and the econom-
    ics of capitalization of such innovations. Stem cell therapy
    is already widespread for some malignant conditions, and
    with advances in genomics and molecular biological tech-
    nology it is very likely to become a major therapeutic inter-
    vention for many more conditions in the coming years. The
    effects of new technology on insurance and managed care
    systems are necessarily involved in decision making as to
    inclusion of new procedures in their service plans.

    Publication in the professional literature is an accepted
    method of establishing the scientific merit of a treatment or
    an intervention. Too rapid diffusion of a medical practice
    can lead to disillusionment and confusion as to the mer-
    its of a particular medical procedure, as happened during
    the 1960s and 1970s with anticoagulant therapy for acute
    myocardial infarction and gastric freezing for peptic ulcers.
    Reviews of the literature should be critical and should
    assess the scientific merits of published data, as well as the
    sources of funding. Well-controlled large-scale clinical tri-
    als are vital to establish the relative values of alternative
    therapeutic approaches, as are meta-analyses of multiple
    studies.

    Dissemination of information about new medical inno-
    vations in the popular media is almost immediate. Many
    major newspapers and television networks have well-
    informed medical reporters and commentators who have

    785

    access to electronic medical journals as quickly as do medi-
    cal specialists in each field. News magazines may carry spe-
    cial articles on new innovations, creating instant demand for
    them as benefits in a health program. This ready access to
    information has both benefits and dangers.

    In the USA, health insurers have led the way in develop-
    ing technology assessment and information synthesis, and
    in evaluating the costs and benefits of new procedures. The
    process is affected by public opinion, as well as by court
    decisions. A landmark decision against a health mainte-
    nance organization (HMO) in 1993 awarded US$29 million
    in damages to the family of a terminal breast cancer patient
    who died following refusal of the HMO to authorize a bone
    marrow transplant, which was at the time an experimental
    procedure. Denial of new technology may lead to increases
    in malpractice suits. In countries with limited financial
    resources, selection of technological innovations in health
    care that can benefit patient care or the public health
    requires a careful balance in order to use limited resources
    well, and to gain from the application of appropriate new
    health care technology.

    Payment systems by national or private insurance
    systems are crucial to introduce and control diffusion of
    technology. Block budgets for hospitals have been more
    effective in Canada than in the USA in restraining the pro-
    liferation of high-tech equipment. This has led to criticism
    of the limited access of Canadians to medical technology,
    such as CT, MRI, and advanced cancer therapies. In the
    USA, universal application of the diagnosis-related group
    (DRG) payment system for Medicare, Medicaid, and most
    private insurance had the effect of increasing ambulatory
    surgery very dramatically, from 16 percent of all surgery
    in 1980 to 80 percent in 2008 of all surgical procedures in
    community hospitals (i.e., non-federal short-stay hospitals
    or 85 percent of all hospitals in the country). Inpatient sur-
    gical procedure rates declined from 85 percent in 1980 to
    35 percent in 2008. Although the rate of visits to hospital-
    based surgery centers remained largely unchanged in the
    USA from 1996 to 2006, the rate of visits to private ambula-
    tory surgery centers increased by about 300 percent.

    HMOs and managed care organizations are paid on a
    per capita basis and have a strong incentive for cost contain-
    ment. They have developed procedures and medical guide-
    lines for investigation and intervention that seek to reduce
    unnecessary procedures. At the same time, HMOs are very
    active in promoting preventive care and non-hospital care
    insofar as this is compatible with good patient care.

    Coronary bypass procedures decreased in frequency in
    the USA between 2001–02 and 2007–08. In the USA, such
    procedures are less frequently carried out in women and
    African Americans, because of lesser access to health insur-
    ance for African Americans and possibly because of biases
    in terms of case assessment criteria in women. Cardiac
    invasive procedures increased dramatically since the 1980s

    786

    in most industrialized countries, but with wide variation in
    their use. The benefits of aggressive invasive management
    of cardiovascular diseases remain controversial, but many
    such procedures have proven beneficial in reducing mortal-
    ity rates and improving quality of life.

    Critical analysis of the need for surgery has resulted in
    lower tonsillectomy and radical mastectomy rates along
    with the increased use of outpatient procedures. Tonsillec-
    tomy, a routine procedure until the 1960s, is now performed
    infrequently since it was found to be of little medical value.
    Cataract surgery is now largely done on an ambulatory
    basis. The technology of home care has come to play an
    important role in early discharge of patients from the hospi-
    tal, as has the wide use of cancer chemotherapy and radia-
    tion therapy on an outpatient basis.

    DIFFUSION OF TECHNOLOGY

    Innovations in health care through scientific and technologi-
    cal advances are continuing, with exciting breakthroughs
    being made in effective new treatments and public health
    interventions, and this requires health authorities, practitio-
    ners, and the public to maintain constant awareness of the
    current state of the art. Diffusion of new technology or adap-
    tations from basic science advances may begin slowly, and
    then reach a “tipping point”, at which time a dramatic change
    of trend occurs and it becomes the new standard or fashion.

    Those with economic interests in the product try to
    advertise and promote sales, while practitioners are ready
    to try new methods to help their patients, but those who
    must pay for services may ask for evidence of effectiveness,
    safety, added value over present and known methods, and
    benefit to the length or quality of life of the individual. This
    can become a highly charged debate when those responsible
    for adopting new measures in national health plans must
    weigh one proposed addition against another, each with its
    ardent professional, community, or business promoters. The
    new HPV vaccine approved by the FDA in 2006 for preven-
    tion of cancer of the cervix is an example.

    The HPV vaccine is recommended for preteen girls at the
    age of 11–12 years and also for females aged 13–26 to off-
    set future sexual exposure to HPV-infected males and since
    2012 recommended routinely for teenage boys as well. The
    two competing main manufacturers of HPV vaccine are nat-
    urally interested in increasing their market and market share,
    and willing to reduce prices. The cost has been lowered
    substantially for use in developing countries if purchased in
    bulk, but costs are still prohibitive unless funded by interna-
    tional donors. Competing low-cost manufacture in India has
    encouraged the two main manufacturers to lower prices to
    seek broader markets. In 2011, one manufacturer lowered its
    price dramatically to US$5 per dose, a 67 percent reduction
    in the current lowest public price. This has allowed GAVI to
    adopt an HPV strategy for developing countries, where 88

    The New Public Health

    percent of cervical cancer deaths occur, with 275,000 deaths
    of relatively young women each year (GAVI, 2011, 2012).

    Pioneering projects promoting visual examination of the
    cervix and local cauterization of abrasions by trained nurses
    and community health workers are meant to increase access
    to care in traditional villages remote from medical centers.
    The duration of immunity and whether booster doses will
    be required are still not known. Policy makers need to con-
    sider whether the same money would have greater benefit
    if used to provide pneumococcal pneumonia and rotavirus
    vaccine for children in developing countries, which would
    quickly save hundreds of thousands of lives. It is likely that
    the wonderful new public health technology that is the HPV
    vaccine will be absorbed quickly into public health prac-
    tice at least in the industrialized countries, and is now being
    introduced by international donor agencies in sub-Saharan
    Africa.

    QUALITY ASSURANCE

    Quality assurance is an integral part of public health func-
    tion and involves ensuring the quality of both health prac-
    titioners and facilities. It is an approach that measures and
    evaluates the proficiency or quality of services rendered.
    Hospital accreditation is a long-standing method of qual-
    ity assurance, providing many generations of health provid-
    ers in North America with first hand experience of quality
    assurance in community hospitals and long-term care facili-
    ties, as well as ambulatory and mental health services.
    Hospital accreditation has contributed to improvement in
    standards of facilities and patient care throughout Canada
    and the USA and has provided a working model for replica-
    tion or adaptation internationally.

    Adverse Events and Negligence

    Iatrogenic diseases are adverse events that occur as a result
    of medical management and result in measurable disability.
    Negligent adverse events are those events caused by a failure
    to meet standards of care reasonably expected of the aver-
    age physician or other provider of care. Hospital-acquired
    infections, anesthesia mishaps, falls, and drug errors are the
    most common iatrogenic events.

    Iatrogenic disease is a major cause of morbidity, pro-
    longation of hospitalization, and even death. Hospital-
    acquired (nosocomial) infections are estimated to occur
    in 7–10 percent of hospital cases in Britain and the USA.
    Primarily these are caused by urinary, respiratory tract, and
    wound infections. It is becoming more common that infec-
    tions involving organisms previously responsive to antibi-
    otics are now resistant to many antibiotics and difficult to
    treat. Infection control in hospitals is therefore an essential
    part of hospital organization. Because hospitals are increas-
    ingly being paid by DRGs, any secondary event prolonging

    Chapter 15 Health Technology, Quality, Law, and Ethics

    hospital stays may have adverse financial effects on the hos-
    pital. In the USA, recent decreases in Medicare reimburse-
    ments for nosocomial infections reflect this trend to provide
    financial incentives to improve hospital infection control.
    There is, therefore, a strong financial as well as professional
    interest in reducing hospital-acquired infections.

    A classic study of 32,000 hospitalizations in New York
    State carried out by a Harvard University team showed
    that 3.7 percent of hospitalized patients suffered adverse
    events or injuries caused by medical mismanagement which
    resulted in measurable disability. Of these, 28 percent were
    due to negligence, so that 1.03 percent of all hospitalizations
    involved medical negligence leading to measurable injury.
    Of the total of some 100,000 adverse events in the study
    group, 57 percent recovered within a month and 7 percent
    had severe injury. Some 14 percent or 14,000 people with
    adverse events died as a result; 51 percent of these deaths
    were due to negligence. A 1999 report of the US National
    Institute of Medicine estimated that between 44,000 and
    98,000 people die annually in the USA from medical errors
    occurring in hospitals, but these data are considered to be
    overestimated in some studies. Adverse drug events (ADEs)
    result in 700,000 emergency department visits and 120,000
    hospitalizations annually, with US$3.5 billion spent on
    extra medical costs. CDC estimates that at least 40 percent
    of the costs of ambulatory (non-hospital setting) ADEs are
    preventable.

    A 2008 report by the Office of Inspector General of the
    US DHHS reported that 13.5 percent of Medicare benefi-
    ciaries experienced adverse events and that for 1.5 percent
    of beneficiaries, these adverse events contributed to their
    deaths. An additional 13.5 percent of beneficiaries in the
    sample experienced temporary harm as a result of their
    medical care, bringing the total percentage of beneficiaries
    experiencing instances of care-related harm to 27 percent.
    Nearly half (44 percent) of these adverse or temporary harm
    events were preventable.

    Hospital-acquired infections cause 99,000 patients
    deaths in the USA every year (AHRQ, 2009). Higher rates
    are seen among the elderly and the poor. Rates are lower in
    teaching hospitals than in community hospitals. About 20
    percent of the events were related to drug reactions or dos-
    age errors. Less than 3 percent of those injured brought civil
    litigation for the negligence. The search for “bad apples” –
    that is, unethical, criminal, or incompetent health providers –
    is necessary, but not sufficient to stem the problems created
    by the health system itself. Prevention requires organized
    activity. Investigation of adverse events helps to identify
    methods of prevention and to protect the patient’s rights.
    A program of measures to reduce hospital infection must be
    based on epidemiological analysis of recorded events in the
    search for common causes and preventable factors.

    Organized surveillance and control requires a ratio of
    one infection control practitioner per 250 acute care beds,

    787

    a trained hospital epidemiologist, and routine reporting of
    wound infections to practicing surgeons (CDC, Hospital
    Infection Program). Computer-aided medication dispens-
    ing, as well as automated and other safety systems are
    critical elements in minimizing morbidity and mortality
    resulting from preventable human errors. In response to
    the high frequency and cost of medical litigation, many
    states in the USA have enacted legislation to restrict court
    awards for medical negligence. Proposals for alternatives
    to the tort system of medical malpractice compensation
    include arbitration and mediation, an administrative sys-
    tem similar to that used for workers’ compensation, and
    a no-fault system of compensation, such as exists in New
    Zealand, Sweden, and Finland. In a no-fault system the
    complainant need not prove negligence on the part of the
    provider, but only that he or she suffered an adverse event
    which is compensable at standard rates depending on the
    degree of disability. In the USA, federal legislation pro-
    vides compensation for vaccine injuries, and three states
    have enacted restricted no-fault systems for birth-related
    neurological injuries.

    In addition, there is greater emphasis on the adoption of
    failsafe mechanisms, such as introducing warning systems
    in anesthesia machines to alert the anesthetist if oxygen
    flow in the patient’s tubing falls below a safe point. This
    system was tested in Boston hospitals and found to reduce
    adverse anesthetic events to zero cases over a 3-year period.
    Vitamin K injection was made mandatory for all newborns
    in New York State, as was already the case in some other
    states, when a study showed deaths from hemorrhagic
    disease of the newborn in cases where vitamin K was not
    administered.

    Inappropriate medical practice patterns are an equal, or
    even larger problem for health systems. Comparisons of
    surgical rates within the USA for coronary bypass proce-
    dures, hysterectomies, and caesarean sections show wide
    variation between different areas of the country. The costs
    of excess surgery not only are economically wasteful but
    also involve risks for the patient from the surgery itself
    or anesthesia mishaps, infection, pain, and discomfort,
    with legal and ethical questions of unwarranted interven-
    tions not for the benefit of the patient. Health systems are
    increasingly required to evaluate and control excess surgi-
    cal, investigative, or other medical procedures, not only for
    financial reasons but also for protection against litigation
    and infringement of patients’ rights.

    Licensure and Certification

    The requirements that society establishes for allowing an
    individual to practice medicine, and any health profession,
    are vital to maintaining and improving the quality of care
    (see Chapter 14). These standards require defining the train-
    ing and experience needed by the individual, examination

    788

    procedures, and recognition for continued education and
    maintenance of competence. This requires a statutory base
    and national bodies operating under a national authority, sep-
    arate from the agency operating the health system services.
    Separation of licensing from operation of the health service
    is essential in maintaining high professional standards.

    The licensing authority is accountable to the state and
    the public. In some cases, this function is delegated to self-
    regulating professional bodies. In Canada, the licensing of
    the medical profession and specialty recognition are carried
    out by the medical profession with self-regulation. In the
    UK, medical licensing is by a state-appointed board and in
    the USA by state boards.

    Medical schools, postgraduate training programs,
    and fellowships are all subject to periodic comprehensive
    assessments. Institutions that fail to meet the standard may
    have funding or licensure suspended until they have per-
    formed adequate remediation.

    Health Facility Accreditation

    Hospital accreditation in North America is by a voluntary
    grouping of professional associations, including the Cana-
    dian and American Colleges of Physicians and Surgeons,
    the hospital associations, and the Colleges of Nurses. The
    Joint Commission, originally operating in both Canada and
    the USA, carries out regular inspections of hospitals. In Can-
    ada, other organizations including the federal Department of
    Health, provincial ministries of health, the Canadian Diabetes
    Association, the Public Health Association, and the Standards
    Council of Canada participate in the Joint Commission as
    observers. Initially focusing on acute care hospitals, accredi-
    tation has been gradually extended to cover special hospi-
    tals, long-term facilities, home care programs, public health
    departments, and ambulatory care services.

    Health facility accreditation is a systematic, multidisci-
    plinary inspection of the physical and organizational struc-
    ture of the facility or program and the functioning of its
    component parts. Factors measured include staff qualifica-
    tions, facilities, organization, record keeping, and continu-
    ing education of staff.

    The process of accreditation requires a request for
    accreditation from the board of governors of the hospital
    or health facility, implying acceptance of the standards
    of the commission. The accreditation process includes a
    self-assessment, an on-site survey, and follow-up action
    for correction of deficits and improvements. The com-
    mission is invited to conduct a survey, and resurvey as it
    sees fit. The hospital pays a fee and commits itself to pro-
    vide all data requested and to cooperate with the site visit.
    The commission issues a confidential report, giving the
    accreditation rating and interim statement of deficiencies,
    and requests progress reports in correcting deficiencies. It
    is also empowered to carry out follow-up inspections and

    resurveys. Box 15.4 lists the areas of a large community
    or teaching hospital, regional health authorities, hospitals,
    and community-based programs and services, from both
    private and public sectors, not only in Canada but around
    the world.

    The assessment survey examines the goals and objec-
    tives of the organization and its administration, the direc-
    tion and staffing of the facility, policies, and procedures.
    Review includes medical staff organization, credentials and
    review procedures, clinical privileges, selection of depart-
    ment chairpersons and their responsibilities, standing com-
    mittees, schedule of meetings, bylaws, and the role of the
    governing board of the hospital. The presence and nature of
    quality assurance organization, records review procedures,
    and continuing educations are assessed. The quality of
    clinical records is assessed by examination of charts for the
    completeness of histories and documentation of the course
    of the hospital stay including laboratory reports.

    Each section of the program being accredited is assessed
    in the following categories:

    l statement of purposes, goals, and objectives
    l organization and administration
    l human and physical resources
    l orientation, staff development, and continuing education
    l patient care
    l quality assurance.

    These categories are also used in the programs covered
    by the contracts between Accreditation Canada, formerly
    the Canadian Council on Health Services Accreditation
    (CCHSA), and other health and social service agencies.

    Hospital accreditation was established in the UK and
    Australia in the 1980s and is attracting interest in other
    countries seeking ways to maintain and promote standards.
    The procedure for accreditation of hospitals is still volun-
    tary in Canada, but in effect has become universal for hos-
    pitals of medium and large size (over 75 beds) and common
    for smaller hospitals. It is seen as advantageous for the gov-
    erning board and the community and also for the medical
    staff in terms of medicolegal protection. In the USA, hospi-
    tal accreditation has become virtually universal since pay-
    ment for federally funded health insurance (Medicare and
    Medicaid) beneficiaries is not allowed for non-accredited
    hospitals, and many private insurers make this requirement
    as well. In some states, accreditation is mandatory for all
    hospitals.

    Since the 1990s, CCHSA’s accreditation program has
    expanded to cover a diversity of health care and service
    areas, through contract arrangements with independent non-
    hospital facilities such as highly specialized programs as well
    as community health and social service organizations. In 2006,
    CCHSA introduced standards for child welfare, hospice, pal-
    liative and end-of-life care facilities, prison facilities, biomedi-
    cal laboratories, and supplementary criteria for telehealth. In

    BOX 15.4 Accreditation Canada Standards

    2008 CCHSA officially became Accreditation Canada, pro-
    viding services to other countries. The ever-changing health
    and social environment now accommodates specialized needs
    in a diversity of service areas as an adjunct to the hospital
    accreditation process. Examples are shown in Box 15.5.

    Licensing and regulation of health facilities are a gov-
    ernment responsibility, but an independent accreditation
    authority has advantages. The national authority may fail to
    monitor its own facilities with the diligence or objectivity
    needed, and there may be a conflict of interest. Where there
    is a national system of organization, distinct departmen-
    talization of the operating and certification functions may
    provide a greater measure of objectivity. Assistance from
    countries experienced in voluntary accreditation can help to
    establish accreditation mechanisms and provide technical
    and professional support to countries wishing to establish
    such programs.

    In the current period of transition from central to decen-
    tralized management of health services in many countries,
    health facilities are being transferred from government

    operation to independent operation as not-for-profit or
    even for-profit facilities. Present methods of regulation by
    national or state levels of government will require review
    as decentralization and privatization take place. Regulation
    by governmental authorities and non-governmental pro-
    fessional bodies is mutually complementary in promoting
    accountability, standards, and quality of services.

    Peer Review

    A large part of the work of clinical and departmental man-
    agers in hospitals or other care settings relates to qual-
    ity assurance. A major method of improving quality in a
    health program is through peer review by which the staff
    organizes systematic review of cases and records, using
    statistics on performance indicators. In hospitals, this
    includes review of deaths, maternal mortality and infant
    mortality cases, surgical rates, complications following
    surgery, and infection rates. Medical records and com-
    puter information systems permit users to review records

    BOX 15.5 Accreditation Canada International
    Accreditation Program

    The Canadian health services accreditation program began
    in 1917 in conjunction with the American College of
    Surgeons (ACS) with a hospital standardization program. The
    first Minimum Standard for Hospitals developed require-
    ments of just one page. In 1918, on-site inspections of hos-
    pitals began, with 89 of 692 hospitals surveyed meeting the
    requirements of the Minimum Standard. In 1926, the first
    Standards Manual was issued.

    In 1951, the American College of Physicians, the
    American Hospital Association, the American Medical
    Association, and the Canadian Medical Association joined
    with the ACS to create the Joint Commission on Accreditation
    of Hospitals (JCAH). It is an independent, not-for-profit orga-
    nization whose purpose is to provide voluntary accredita-
    tion. In 1953, the Canadian Hospital Association (now the
    Canadian Healthcare Association), the Canadian Medical
    Association, the Royal College of Physicians and Surgeons,
    and l’Association des Médecins de Langue Française du
    Canada established the Canadian Commission on Hospital
    Accreditation. The Commission’s purpose was to create a
    Canadian program for hospital accreditation, and in 1958
    the Canadian Council on Hospital Accreditation (CCHSA)
    was incorporated.

    In 2008 CCHSA became Accreditation Canada
    International. The accreditation program is used by all
    types of health facilities, from large and complex hos-
    pitals, to health systems, community health organiza-
    tions, and residences providing long-term care. Its scope
    includes a wide range of programs, including standards
    on child welfare, hospice palliative and end-of-life care,
    biomedical laboratory services, blood banks, and supple-
    mentary criteria for Telehealth. The accreditation program
    covers a diversity of health care and service areas, service
    programs for brain injury, ambulatory care, assisted repro-
    ductive technology – clinical and laboratory services,
    Canadian Forces health services, cancer agencies, child
    welfare organizations, First Nations and Inuit addictions
    and community health services, the Federal Department
    of Veterans’ Affairs, substance abuse and problem gam-
    bling treatment services.

    The accreditation service is on a contract basis with
    specialized health programs, other federal government
    departments, for-profit health facilities, and community
    organizations across the provinces.

    Accreditation Canada International works with other
    countries to develop national accreditation programs for
    their countries, and launched its first international program
    for acute care, primary care, ambulatory care, and clinical
    laboratories in 2010.

    by diagnosis. These records can be utilized to assess other
    events in hospitals, such as time from admission to sur-
    gery, lengths of stay by diagnosis, response to abnormal
    laboratory findings, and many other indicators of the pro-
    cess of care. Obstetric departments can review the fre-
    quency of and criteria for caesarean section deliveries.
    Surgical departments review their appendectomy rates to
    separate pathological findings from normal appendices.
    Organized peer review has also been called medical audit
    and essentially describes methods of self-policing and
    education to learn from mistakes and experience and to
    improve the quality of care.

    In 1972, an amendment to the US Social Security Act
    required hospitals and long-term care facilities to moni-
    tor the quality of care given to Medicare and Medicaid
    patients through professional standards review organiza-
    tions (PSROs). These were medical audit committees with
    specified tasks to conduct utilization review, medical care
    evaluation, and profile analysis of physician or institutional
    performance compared to accepted standards of the medical
    community. In 1982, peer review organizations (PROs) were
    created by federal statutes to replace PSROs. The PROs are
    non-profit corporations, staffed by physicians and nurses,
    to review medical necessity, quality, and appropriate level
    of care under the Medicare and Medicaid programs. The
    Centers for Medicaid and Medicare Services have an Office
    of Clinical Standards to conduct surveys, provide certifica-
    tion, and develop best practices guidelines, in a health care
    quality improvement program (HCQIP).

    Hospitals have departmental clinical meetings, adverse
    incident or outcome committees, mortality rounds, and
    clinical pathology conferences to help staff to evaluate and
    learn from difficult cases. The presence of functioning peer
    review mechanisms indicates that quality is of concern to
    the professional and administrative network, raising the
    consumer’s confidence in the system.

    Maternal mortality committees have been widely used
    to assess preventable factors in deaths related to maternity
    and to point out areas of needed improvement in services.
    Identification of high-risk pregnancies emerged from this
    process and has become an important part of prenatal care.
    Infant mortality reviews by professional groups can simi-
    larly demonstrate areas of needed improvement in services.
    Death rounds are held to review cases of death following
    surgery or soon after admission, or “incidents”, such as
    inappropriate medication given in error.

    The successive waves of peer review initiatives in
    the USA represent attempts by the federal government
    to establish mandatory quality of care review by profes-
    sional peers for facilities providing care to Medicare and
    Medicaid patients. The concept of requiring standards of
    care review has probably contributed to a greater aware-
    ness of the accountability of hospital-based practice. Fre-
    quent litigation may have contributed more to the sense that

    Chapter 15 Health Technology, Quality, Law, and Ethics

    the physician is accountable for services and outcomes of
    care. PROs are a form of quality regulation that represent a
    commitment by funding agencies to accountability in care
    systems and to identification of organizational and admin-
    istrative weaknesses in health care generally and not only
    in hospitals. The generation of US physicians and health
    systems managers trained since the 1970s accepts peer
    review as an integral part of health services. Other coun-
    tries use this kind of mechanism to maintain and promote
    quality of care.

    Tracer Conditions

    Tracer conditions are common medical conditions (or pro-
    cedures) for which diagnostic criteria are well established
    and clear, there are effective preventions or treatments, and
    a lack of treatment can cause significant harm to the patient.
    Examples of tracer conditions include otitis media, appen-
    dectomy, caesarean section, and hysterectomy. These con-
    ditions, if evaluated in terms of incidence and actual chart
    review, can provide useful insights into departmental medi-
    cal standards. Incident reports by nursing staff and nosoco-
    mial infections are examples of the functioning of the tracer
    condition concept.

    Incident reports in hospitals are designed to determine
    the causes of errors, so that remedial action can be taken
    and similar events prevented. Tracer condition studies have
    become such an accepted part of modern health manage-
    ment that the absence of an organized review system could
    be considered a serious structural flaw in a health service,
    requiring remedial action.

    Setting Standards

    Standards recommended by independent professional
    organizations or by advisory committees appointed by
    ministries of health can play important roles in defining
    standards of care for specified conditions. In addition,
    organized professional bodies can issue practice guidelines
    or help governments or health care agencies to develop
    standards or algorithms for management of specific topics
    and conditions.

    Specifying standards for preventive care, such as for
    infants and adults, assists local health authorities in plan-
    ning and evaluating services. The American Academy of
    Pediatrics (AAP) has an extensive professional committee
    structure that publishes periodic guidelines for pediatricians
    on a wide variety of infant and child topics including nutri-
    tion, immunization, prevention of anemia and lead toxicity,
    child safety, and school health. Mandatory preventive care
    for newborns includes eye care and vitamin K injection in
    the USA (see Chapter 6). Mandatory immunization require-
    ments for school entry and for health care personnel are dis-
    cussed in Chapter 4.

    791

    The American Public Health Association (APHA) pub-
    lishes the Control of Communicable Diseases Manual, now
    in its nineteenth edition (2008). It is the authoritative US
    manual on this topic. The AAP’s Red Book on infectious dis-
    eases is used across North America by pediatricians in clini-
    cal practice. These organizations and their counterparts in
    obstetrics and many other clinical fields directly relevant to
    public health continually update practitioners and policy per-
    sonnel in the “state of the art” or “gold standard”, discussed
    previously. This constitutes a professional self-guidance sys-
    tem in standards. Managed care and other health provider
    systems also issue guidelines for member practitioners that
    serve to maintain standards of service.

    The wide use of treatment protocols and scoring systems
    in hospital medicine helps to define standards of care in a
    measurable way. The Apgar score for rating newborn sta-
    tus has been a standard in hospitals worldwide for decades,
    helping to standardize infant assessment and care. The
    APACHE (Acute Physiology And Chronic Health Evalua-
    tion) scoring system is used widely to assess the chances
    of survival of patients admitted to intensive care units and
    to compare outcomes, for example, between teaching hos-
    pitals and community hospitals. It is also used in assessing
    patient outcomes with different modes of treatment. Scor-
    ing systems are also used in community health care, as in
    risk scoring for pregnancy care (see Chapter 6).

    Algorithms and Clinical Guidelines

    Algorithms are decision trees or a systematic series of deci-
    sions based on the outcomes of previous decisions, tests, or
    findings. Derived from operations research, this approach
    applied to medicine identifies all available choices (e.g.,
    exposed versus non-exposed) and follow-up decisions
    based on findings from each previous option substantiated
    by observation. It is often presented graphically like the
    branches of a tree, showing the alternatives and subsequent
    decisions to be made.

    A clinical algorithm is a systematic process defining
    a sequence of alternative, logical steps depending on out-
    comes of previous ones, incorporating clinical, laboratory,
    and epidemiological information, applied to maximize ben-
    efits and minimize risks for the patient. It gives the provider
    a review of the relevant literature and recommended stan-
    dards of practice on a particular topic for preventive care
    or case management. These guidelines are usually arrived
    at by consensus of multidisciplinary working groups taking
    into account published studies on the topic. The guidelines
    may suggest that some procedures should not be carried out
    routinely.

    Clinical guidelines are meant to establish accepted stan-
    dards of care and may have important economic implica-
    tions. Medical Letter, published by the Consumers’ Union,

    by respected, experienced, and competent medical authori-
    ties. Clinical practice guidelines are produced by hundreds
    of professional, medical, and governmental agencies in
    order to standardize and improve medical care.

    Clinical and preventive care guidelines are helpful
    in clinical practice and in preventive medicine. They are
    increasingly used in managed care environments to assure
    standards, quality of care, and cost-effectiveness as well as
    legal protection. Guidelines for preventive medicine and
    public health practice are also part of the process of pro-
    moting the quality of individual and community health,
    as discussed in Chapter 11. Annual revision of the infant

    immunization program, discussed in Chapter 4, is a prime
    example, as is the set of guidelines for preventive care for
    adult health maintenance in Table 15.5.

    The issue of application of current scientific knowledge
    for population health is a continuing struggle for recognition
    of the prime importance of health promotion and preventive
    care for health of a population. The selection of priorities in
    use of resources is vital especially in the many developing
    countries that are in various stages of economic development,
    or which have abundant income from natural resources such
    as oil and minerals. Implementation of programs designed to
    achieve the MDGs can help to serve this purpose.

    Public health standards and clinical practice guidelines
    are an increasing part of quality improvement. It is impor-
    tant, however, that they are developed as best practices and

    influenced as little as possible by commercial interests of
    drug or vaccine manufacturers. The proliferation of such
    guidelines by health authorities or professional associations
    of the USA, the UK, Canada, Australia, and other countries
    indicates a wide consensus on the importance of such writ-
    ten standards, guidelines, or “best practice” statements. The
    recommended childhood immunization program put for-
    ward annually by the CDC in conjunction with the AAP and
    other professional organizations is an example of such best
    practices and is accepted by health insurers and providers as
    the gold standard in this field. The concept of promotion of
    quality in health care and the adoption of current scientific

    The Canadian Province of Saskatchewan Health Ser-
    vices Utilization and Research Commission publishes peri-
    odic reports presenting consensus positions of panels of
    medical faculty, clinical specialists in pathology and physi-
    cal medicine, and public health specialists in nutrition, com-
    munity health, and epidemiology. Its reports are circulated
    widely and serve to update medical practitioners, reduce
    unnecessary testing, promote appropriate use of laboratory
    and other diagnostic procedures, and provide standards of
    care for individual patients and community services, such
    as long-term care facilities and home health agencies.

    The Canadian Medical Association issued its Handbook
    on Clinical Practice Guidelines in 2007, based on a system-
    atic review of the literature, interviews of key professionals,
    consensus conferences, and continuing evaluation of both
    process and content of such guidelines. The Guideline Inter-
    national Network (GIN) Fourth International Conference,
    held in Toronto in 2007, involved experts in national and
    international practice guidelines from 31 countries to share
    experience and concepts in this ongoing field. The GIN
    library contains more than 6600 (by October 2012) guide-
    lines, evidence reports and related documents, developed or
    endorsed by GIN member organizations (GIN, 2012).

    An Institute for Clinical Evaluation (ICES) organization
    at the University of Toronto, established in 1992 with core
    funding provided by Ontario’s Ministry of Health and Long
    Term Care, is mandated to conduct research that contributes
    to the effectiveness, quality, equity, and efficiency of health
    care and health services in Ontario. ICES uses an interdis-
    ciplinary research approach to health care, health services,
    and health policy.

    The American College of Cardiology (ACC) provides a
    framework of evidence-based clinical statements and guide-
    lines developed by leaders in the field of cardiovascular med-
    icine with continuing adoption of new scientific information
    and experience in many aspects of this field (ACC, 2012).
    Many professional organizations such as the AAP, American
    Congress of Obstetricians and Gynecologists (ACOG), UK
    Faculty of Public Health, and European Society of Cardiol-
    ogy produce clinical guidelines which are updated regularly
    to provide physicians and health systems managers with
    current consensus on state-of-the-art standards, such as the
    European Society of Hypertension Guidelines released in
    2013 (i.e., less than 140 mm. systolic for all).

    The US Health Care Financing Administration (HCFA),
    Center for Medicare & Medicaid Services (CMS), and
    National Institutes of Health (NIH) have consensus pro-
    grams to develop guidelines that are widely disseminated
    and set standards of practice. In 1977, the NIH issued its
    first consensus paper on breast screening for cancer, and
    this has been followed by many other topics each year
    since. The AHRQ also produces research related to efficacy
    of current and new practices and training material to pro-
    mote their diffusion across the US health system. Cochrane

    http://www.cdc.gov/od/science/excellence/

    794

    reviews and the Cochrane Library provide high standards of
    literature reviews and meta-analysis on many topics which
    serve to guide practitioners and policy makers in current
    standards. The US Healthy People 2020 project provides
    gold standards for preventive care which serve clinicians,
    public health practitioners, and health planner standards
    for their work. Evidence-based consensus guidelines were
    issued on the following topics: breast cancer screening
    for women aged 40–49, interventions to prevent HIV risk
    behavior, management of hepatitis C, genetic testing for
    cystic fibrosis, acupuncture, and effective medical treat-
    ment for heroin addiction.

    Clinical guidelines are increasingly being promoted
    by professional, governmental, and managed care orga-
    nizations with the purpose of promoting rational use of
    health care resources and at the same time promoting
    standards of care to incorporate good standards of clinical
    practice. Clinical practice guidelines are now common in
    the practice of primary care, mental health, and clinical
    specialties. The University of Southern California’s list
    of clinical guidelines website (http://medicine.ucsf.edu/)
    provides access to hundreds of websites for such practice
    guidelines.

    Clinical guidelines provide practicing doctors, peer
    review committees, health care managers, managed care
    companies, governmental bodies, and professional organi-
    zations with channels to set standards of practice and expec-
    tations of care standards. Legal aspects of health care also
    increasingly recognize the importance of clinical guidelines
    where committees of appropriate medical professionals
    convene and set out average or minimum standards of care
    for defined clinical entities. Thus, peer-reviewed guide-
    lines set an appropriate standard (a silver if not a gold stan-
    dard) for judging malpractice or adequate practice. Clinical
    guidelines should be under periodic review and subject to
    critical discussion and updating using the Cochrane review
    methods of literature review and analysis. Promotion by
    advocacy or special interest groups can be constructive,
    but the influence of drug companies can be insidious and
    reduce the professional objectivity of such reviews and their
    recommendations, a concern that must be carefully moni-
    tored and continuously kept in mind as a potential compro-
    mising bias.

    The AAP produces policy statements, practice param-
    eters, and model bills which have a wide distribution and
    influence; they are published in the academy’s journal, Pedi-
    atrics. The AAP clinical practice guidelines issued include
    diagnosis and treatment of urinary tract infection in febrile
    infants and young children, long-term treatment of the child
    with simple febrile seizures, management of acute gastroen-
    teritis in young children, management of otitis media with
    effusion in young children, and others. The policy state-
    ments of the AAP cover a wide range of topics including
    use of bicycle helmets, 55 mile per hour maximum speed

    The New Public Health

    limits, folic acid for the prevention of neural tube defects,
    and ethics in the care of critically ill infants and children.
    AAP guidelines are valid for 5 years only and are reissued
    or reconfirmed in order to keep up to date and to incorporate
    new or revised knowledge into practice standards.

    Empirically derived, peer-reviewed, regularly updated
    guidelines have become an appropriate standard for prac-
    tice and for judging malpractice, as well as balancing qual-
    ity and cost-effectiveness. Clinical guidelines may become
    restrictive, but they help to reduce practice by whim and
    unsubstantiated belief to improve the quality of care over-
    all. In large health care organizations they provide a basis
    for continuing education for staff and advancement of stan-
    dards of the organization.

    The Community Guide produced by the CDC provides
    an excellent source of evidence-based advice for community
    programs. It serves the needs of public health professionals,
    health care providers, legislators and policy makers, research-
    ers, community-based organizations, employer–employee
    groups, and other purchasers of health services. The guide
    covers a wide range of health issues including alcohol, can-
    cer, diabetes, mental health, motor vehicle safety, nutrition
    and obesity, oral health, physical activity, pregnancy, sexual
    behavior, social environment, substance abuse, tobacco, vac-
    cines, violence, and workplace health issues.

    In 1999, the UK National Health Service (NHS) estab-
    lished the National Institute for Clinical Excellence (NICE)
    as an independent organization to provide guidelines for
    public health, health technologies, and clinical practice
    guidelines for specific conditions. The Health Development
    Agency of the NHS was included in the NICE organization
    in 2005. Now called the National Institute for Health and
    Care Excellence, NICE publishes guidelines that provide a
    helpful basis for clinical practice and public health as well
    as other areas in the NHS to update the services provided.
    Topics for public health include smoking and tobacco con-
    trol, diet and obesity, exercise and physical activity, sexual
    and mental health, and alcohol.

    ORGANIZATION OF CARE

    Administrative and financing systems are essential ele-
    ments of quality assurance. They can be designed to pro-
    mote standards of care and to reduce fiscal incentives that
    foster excess supply and overservicing. The organization
    of financing health care has important implications for
    quality, technology, and ethical issues in the New Public
    Health.

    Diagnosis-Related Groups

    DRGs, discussed extensively in Chapter 11, were developed
    in the 1960s as an alternative way of paying for hospital care
    in order to encourage shortened lengths of stay. Experience

    http://medicine.ucsf.edu/

    Chapter 15 Health Technology, Quality, Law, and Ethics

    with payment by days of care (per diem) showed that it pro-
    moted unnecessary, lengthy, and potentially dangerous use
    of hospital care, an important factor in the rapid escalation
    of costs in the health system. DRGs were adopted for pay-
    ment for Medicare beneficiaries in the USA in 1983 and
    later became the standard method of payment for all insur-
    ance systems.

    In the DRG system the insurer pays the provider hos-
    pital for a procedure or diagnosis rather than the number
    of days of stay in hospital. This has led to a large reduc-
    tion in hospital days of care and a remarkable growth in the
    number of surgical procedures done on an outpatient basis.
    Since the introduction of DRGs, outpatient surgical proce-
    dures have grown from less than one-fifth to more than half
    of inpatient surgical cases. Outpatient surgery is safer for
    the patient and less costly to the insurer. DRGs have gradu-
    ally been adopted as a case payment system for reimbursing
    hospitals in most developed countries.

    The DRG system is widely considered to promote qual-
    ity of care as an active process focusing on quickly address-
    ing the diagnosis and management of the patient with rapid
    mobilization of treatment and return home. Critics of this
    system allege that DRGs encourage inappropriate early
    discharge of patients before optimal patient education and
    follow-up care have been provided, but long length of hos-
    pital stay has not been shown to improve patient outcomes.
    Critics also suggest that this may promote altering diagno-
    ses to higher cost units of service. Others think that DRGs,
    by reducing length of stay, have turned hospitals into inten-
    sive care units with ultra-sick patients. Despite these issues,
    the trend towards short hospital stays and newer approaches
    to active treatment seems to be compatible with better care
    and improved outcomes, according to some measures. The
    rapid decline in mortality rates from coronary heart disease
    is thought to be due in large part to the activist treatment
    approach, with lengths of stay of 1 week or less for acute
    myocardial infarction compared to 6 weeks on average up
    to the 1970s.

    Managed Care

    Managed care systems developed in the USA in response
    to rapid cost escalation for health care and the successful
    experience of HMOs. Managed care is based on the con-
    cepts of resource management, and quality assurance with
    rationalized use of technology. The system developed over
    time with checks and balances to provide comprehensive
    care at lower cost than traditional fee-for-service systems
    by discouraging excessive utilization without compromis-
    ing quality of service. Managed care systems include tradi-
    tional HMOs and various other organizations which employ
    physicians or are made up of independent physicians work-
    ing together who own or contract for hospital services (see
    Chapter 10).

    795

    HMOs, both for-profit and not-for-profit, and man-
    aged care itself, have been widely criticized as excessively
    limiting patient access to appropriate care in the interest
    of cost containment. The 2010 PPACA (Obamacare) is
    promoting development of newer innovations including
    patient-centered medical homes (PCMH), accountable
    care organizations (ACOs), and population health man-
    agement systems (PHMSs), and early evidence shows that
    these models are quality management approaches for inte-
    grated primary and hospital patient care (see Chapter 11).
    Obamacare is a highly politicized and much debated topic
    in the USA; it seems likely to make a very big difference
    in coverage and fair practices of insurance with lower
    costs of private insurance.

    District health systems in the UK, the Scandinavian
    countries, and the post-Soviet model of health care incor-
    porate organizational and financial linkage between care
    systems and funding from tax sources. HMOs, sick benefit
    funds, and district health systems provide both prepayment
    and health services. Even in traditional private health insur-
    ance systems, the insurer is increasingly taking on the role
    of regulating reimbursement for medical services in order to
    contain costs and curb abuses by providers. In this context,
    emphasis is placed on maintaining health, preventive care,
    and financial incentives to efficiency in overall care. Clini-
    cal indications, utilization review, and organizational and
    professional standards are now becoming accepted parts of
    the health insurance milieu.

    The competition between hospitals for referrals from
    managed care plans in the USA has created a market
    situation in which a high proportion of hospital beds are
    empty, and in which mergers or closures of hospitals
    are common. Closures or reductions in hospital bed sup-
    ply are also occurring in the UK and in most industrial-
    ized countries of Europe.

    PERFORMANCE INDICATORS

    Performance indicators are measures such as morbidity,
    mortality, functional status, or immunization rates in a com-
    munity, used to monitor the functioning of a health service.
    Routinely collected statistics are analyzed to compare per-
    formance against objectives, help monitor efficiency and
    effectiveness, point out problem areas within the service,
    and plan new health programs. This method is based on the
    use of the concept of management-by-objectives in health
    administration to promote achievement of national health
    targets.

    The UK has a strong tradition of mapping diseases as a
    basis of epidemiological analysis and has applied this strat-
    egy to mapping of performance indicators to assess health
    care performance. The UK financing system is based on
    capitation adjusted by standardized mortality rates on the
    premise that mortality rates standardized and compared to

    796

    the national average serve as indicators of need. In this way,
    the approach helps to promote equitable funding among
    wealthy and poorer regions of the country, and thereby
    improve services in areas of greater need.

    Performance indicators were introduced into the NHS
    during reforms of the late 1980s, providing a series of
    outcome or performance measures that are used to adjust
    payments allocated on a per capita basis to district health
    authorities. These authorities can be penalized for low rates
    of immunization, whereas general practitioners receive
    incentive payments for full immunization coverage. The
    result was a rapid improvement in immunization coverage
    of infants and children compared to rates in the previous
    decade. Incentive payments in many countries encourage
    women to go to hospitals for delivery or to attend prenatal
    care by making social maternity grants conditional on seek-
    ing care.

    Use of performance indicators requires the development
    of health information systems with district health profiles
    to provide ongoing monitoring of health indicators in a dis-
    trict, compared to regional and national rates and targets.
    Health profiles help to establish and monitor the prevalence
    of chronic disease and measure the impact of health ser-
    vices. This enables the study of the performance of preven-
    tive and curative services, such as managing hypertension
    to reduce the incidence of strokes and related conditions.
    There are criticisms of performance indicators alleging a
    potential for manipulation and abuse of health intervention
    measures when the financial incentives are used for a spe-
    cific activity. However, financial incentives are part of the
    DRG system and have been successfully used in the UK to
    improve vaccination coverage and implementation of other
    preventive health practices by family physicians. In Israel in
    2007, payments to hospitals provided a bonus for surgical
    interventions for hip fracture within 48 hours of the event,
    resulting in a marked rise in early intervention and a reduc-
    tion in mortality from hip fractures.

    CONSUMERISM AND QUALITY

    With decentralization and the growth of managed care,
    health systems must increase their attention to the attitudes
    of the consumer. Quality is, in part, how the client per-
    ceives the system, and how the system meets client needs
    in an acceptable manner, where privacy, dignity, the right to
    know, and the right to a defined set of services are protected.
    However, the rights of the client are not unlimited. A public
    or private health plan has the duty to manage the basket of
    services responsibly, which includes limitations such as in
    access to specialist services.

    Patients’ rights and consumer protection in health care
    often (but not always) include the right to select and change
    a health care provider, as well as the right to receive high-
    quality care for a designated range of services. The UK NHS

    The New Public Health

    issued a patient’s Charter of Rights during the 1990s, which
    is perhaps idealistic and may not be actualized in practice,
    but still outlines an ideal of value both for practical applica-
    tion and for legal rights. The consumer’s formal protection
    includes the right to complain and to seek redress of grievance
    and compensation for injury suffered from neglect or incom-
    petent care (Box 15.7). In North America and Europe, there
    are at least four models of defining the rights of patients: the
    paternalistic model, the informative model, the interpretive
    model, and the deliberative model (WHO, 2012). Many new
    charters have been established such as data protection, end-
    of-life care, mental health, access to health services, quality
    of care and care giving environment, nationally approved
    treatments, drugs and programs, respect, consent and confi-
    dentiality specific to the UK and in Canada, New Zealand
    and other countries. The new US federal Affordable Care Act
    of 2010 (PPACA) includes a large element of patient’s rights
    protection, as discussed in Chapter 10.

    The patient or consumer of health care needs to be
    informed and conscious of health care costs if efforts to
    restrain cost increases are to be effective. Public attitudes
    are vital in terms of self-care, demands on the health service,
    and limitations to the potential of health care and resources
    for health care. The media and consumer organizations can
    play important roles in advocacy for health, in raising pub-
    lic consciousness of self-care, and as watchdogs on abuses.

    Consumer acceptance is manifested through choice of
    health plan and practitioner, or by seeking alternative care

    BOX 15.7 Patients’ Rights, European Union, 2009

    A review of patients’ rights in countries of the European
    Union in 2009 focused on the following:
    l Right to informed consent based on access to informa-

    tion for care or participation in research
    l Right to information concerning own health, diagnosis
    l Right to medical records
    l Right to confidentiality of personal and health informa-

    tion and physical privacy during care
    l Right to complain and compensation
    l Right of free choice of provider and of treatment
    l Respect of patient’s time
    l Right to observance of quality standards access to high-

    quality health services
    l Right to safety and freedom from harm caused by the

    poor functioning of health services, medical malpractice
    and errors, and the right of access to health services and
    treatments that meet high safety standards

    l Right of access to innovative procedures, including diag-
    nostic procedures, according to international standards and
    independently of economic or financial considerations.

    Chapter 15 Health Technology, Quality, Law, and Ethics

    privately when service is unacceptable because of quality or
    style. Erosion of confidence in a public system of care can
    lead to a two-tier system with the public system serving the
    poor and a private parallel system serving the middle and
    wealthy classes. Such a division can seriously undermine a
    public system unless it is addressed by improving the qual-
    ity and manner of the service and by establishing supervi-
    sion and limitations on public and private practice.

    The growing inequality caused by the rise of private
    practice outside a national health care system is a chronic
    problem in the UK’s NHS, in Israel’s health system, and in
    many countries developing their health systems through par-
    allel public and private care. The issue is also surfacing in
    the USA in the transition to managed care with its inherent
    limitations of choice for people insured through their place of
    work or covered under the Medicare and Medicaid programs.

    The PPACA requires insurance companies to accept any-
    one requesting cover without restrictions due to prior con-
    ditions or high expenses for serious conditions, and without
    other forms of discrimination common in the past. It also
    includes provisions for coverage of preventive care services
    and incentives for quality improvement. Extra billing, banned
    in Canada’s national health insurance plan, is a recurring
    issue with the medical profession in some provinces.

    Consumer knowledge, attitudes, beliefs, and practices
    are part of the health system, from health promotion to
    tertiary care. Informed and health-conscious consumers
    are stronger partners in the health system in achieving
    improved health than an ill-informed and apathetic public,
    so that health education and health promotion are funda-
    mental to modern public health. The role of the consumer
    in health care is unique in that there is a significant infor-
    mation asymmetry between the consumer and provider.
    Health education programs and wide use of the Internet
    increase access to health and medical information, but this
    gap can never completely be eliminated. Patients may use
    their power as consumers to demand inappropriate care,
    such as unnecessary surgery or antibiotics when clearly
    not indicated, because of their preference for interven-
    tion and action over watchful waiting. However, there is
    an equal or perhaps greater danger of provider-induced
    demand for repeated and possibly unnecessary interven-
    tions that may be related to methods of paying the doctor
    or the hospital. The traditional doctor–patient relationship
    is still an important factor for the interests of patients and
    their health. A still effective method of having an individ-
    ual quit smoking is a brief but stern lecture by the family
    physician.

    THE PUBLIC INTEREST

    Population-based interventions are often more effective
    and less costly ways to reduce morbidity and mortal-
    ity than individual prevention or treatment services. A

    797

    population-based preventive program may require behav-
    ior change by the individual, such as in mandatory seat
    belt and motorcycle helmet enforcement or banning smok-
    ing in public places. Fortification of flour, milk, and salt
    with essential micronutrients is a well-established public
    health measure. There is an element of compulsion in this,
    with the social gain usually considered to be sufficiently
    important to outweigh individual rights. Immunization
    is for the protection of individuals but also for the popu-
    lation, so that refusals to immunize children and adults
    can cause injury to others. Herd immunity is protective
    of people who are at high risk. Mandatory immunization
    for school entry in the USA has been effective in increas-
    ing coverage to levels akin to the most advanced health
    systems, over 95 percent coverage. Refusals and failure to
    harmonize immunization policies in Europe have resulted
    in mass epidemics of measles, rubella, and mumps in
    recent years.

    There is often a delicate balance between community
    rights and individual rights which can lie at the heart of
    many controversies in modern public health and health
    care, ranging from chlorination or fluoridation of com-
    munity water supplies to managed care systems for
    health services. Women’s rights, gay rights and abortion
    are highly controversial and politicized in the USA, and
    in many other countries. The differences can become
    extreme and the source of international strife, such as in
    the movement to promote fundamentalist Sharia law in
    many countries that are severely restrictive of women’s
    and minority rights.

    In public health, issues should be examined on their
    merits, especially in terms of what is accepted as good pub-
    lic health practice, based on evidence from clinical trials,
    documented experience, and best practices in other coun-
    tries. The evidence of successful public health measures in
    improving individual and collective health status is power-
    ful, yet must always be balanced within the context of indi-
    vidual rights and the public interest. The ethical issues of
    individual and community rights of public health are dis-
    cussed later in this chapter.

    TOTAL QUALITY MANAGEMENT

    Total quality management (TQM), as discussed in Chap-
    ter 12, was adapted from business management theory and
    practice to health care in the 1990s and provides a basis for
    promoting continuous improvement in health care systems.
    TQM involves everyone in the system, from all levels of
    management to production or service personnel and sup-
    port staff, and thus helps to raise staff morale because of the
    shared involvement. Health is provided through multidisci-
    plinary groups which need to approach problems with open
    and shared scientific inquiry and hypothesis formation, test-
    ing, and revision to find operational solutions to problems.

    798

    Electronic health records and information technology pro-
    vide many new opportunities to improve patient care and
    data systems for monitoring the health status of population
    groups for process and outcome measures, or health targets,
    such as immunization coverage, or screening compliance
    for colon, cervical, or breast cancer, as measures of perfor-
    mance in primary care. Information technology adds a great
    deal of capacity for quality monitoring and improvement
    measures.

    TQM incorporates statistical methods, comparing varia-
    tions in patterns of service or use of resources. It employs
    epidemiological methods to draw conclusions for policy
    needs. It looks for continuous improvement, encouraging
    cooperation, and motivation to achieve common goals of
    service and client satisfaction. Psychological theory helps to
    foster higher levels of motivation, with early identification
    and resolution of conflict. Leadership is shared, and there is
    a basic need for cooperation. Cost and quality are interre-
    lated, as poor quality leads to waste, inefficiency, and dis-
    satisfaction of both clients and staff. High-quality, humane,
    and effective services are especially important in a competi-
    tive environment where clients have the right to choose and
    where costs and efficiency are factors in the well-being and
    indeed the survival of institutions.

    Medical care is increasingly practiced in larger health
    care organizations. To provide technically competent
    medicine is not by itself sufficient. The patient’s rights
    and sense of personal worth are also of great importance.
    Financial incentives can be effective in redirecting health
    care priorities, such as in reducing hospital length of
    stay and admissions, but may result in the patient or the
    family feeling that they are not receiving the best care.
    DRGs, HMOs, and other organizational and funding sys-
    tems meant to increase efficiency of care may have the
    effect of alienating patients from a health care system.
    Staff attitudes towards patients are important for client
    satisfaction. The service must include ready access to
    a continuum of supportive services, such as home care
    and counseling, so that the patient and family do not feel
    abandoned by the system.

    A byproduct of TQM is continuous quality improve-
    ment (CQI), by which institutions wishing to improve qual-
    ity train and empower the staff to work in teams to assess
    their own performance and seek solutions to problems in
    their operational unit. People of different ranks and profes-
    sions work in a network organization as well as in a tradi-
    tional hierarchical organization in which rank and seniority
    provide authority. This community of practice is important
    for staff morale and a shared sense of responsibility for the
    patient and the institution.

    CQI involves multidisciplinary approaches, not only
    to review problems but also to seek better ways of func-
    tioning and improving consumer satisfaction. The process
    includes all those involved in providing care, support ser-
    vices, and administration of a department, hospital, clinic,

    The New Public Health

    or community health program. This is not only professional
    self-policing but a method to find better ways of meeting
    needs and using resources. The involvement of all provid-
    ers improves motivation and promotes a sense of common
    purpose in the organization.

    Applying these principles in a health care setting can
    take many forms. Selection of topics by TQM/CQI com-
    mittees in a hospital or another health facility may be
    based on surveys or interviews with staff, patients, or
    management. Satisfaction surveys among women follow-
    ing delivery in an obstetrics unit could point out remedi-
    able problems. An obstetrics department may be faced
    with issues related to high or low volume of deliveries,
    staff training, equipment and supplies, communica-
    tion among staff, and among staff and patients and their
    families, cleanliness, sterile technique, staff satisfaction,
    client satisfaction, and many others. The team looking
    at such a problem should be multidisciplinary, and the
    emphasis should be on client attitudes and satisfaction.

    Examination of the function of an emergency depart-
    ment in a hospital would similarly look at many functional
    and attitudinal aspects of the service including staff atti-
    tudes, training needs, waiting times, consultation ser-
    vices, and others. Addressing waiting times, for example,
    can lead to ways to reduce these substantially, improving
    both client satisfaction and the efficient management of
    the emergency department. Any service is there to serve
    patients and the community. A service is not primarily for
    the benefit of the staff, but staff satisfaction and morale are
    essential for successful service to clientele. CQI can also
    be applied to assessing and improving compliance with
    clinical guidelines or evidence. An example is assessing
    the proportion of diabetics whose hemoglobin A1c (HbA1c)
    is measured at least twice annually, who have eye and
    feet examinations regularly, or whose blood pressure is
    managed with an angiotensin-converting enzyme (ACE)
    inhibitor.

    The European Region of the WHO and the national
    medical associations in Europe agreed in 1995 that medi-
    cal associations should take leading roles in programs of
    CQI to achieve better outcomes of health care in terms of
    functional ability, patient well-being, consumer satisfac-
    tion, and cost-effectiveness. This is in keeping with the
    European Region’s Health for All targets: there should
    be structures and processes in all member states to
    ensure continuous improvement in the quality of care and
    appropriate development and use of health technolo gies.

    The introduction in the 1990s of general practitioner
    fundholding for hospital care for patients on the general
    practitioners’ roster in the UK encouraged the hospital to
    maximize patient satisfaction with the care system. This
    promotes application of CQI to improving the quality and
    acceptability of care. Similarly, performance indicators
    provide regional and district health authorities in the UK
    with tools for CQI approaches. The UK NHS established

    799Chapter 15 Health Technology, Quality, Law, and Ethics

    The National Institute for Clinical Excellence (NICE), estab-
    lished in 1999, has a mandate to review health service treat-
    ments and effective therapies that should be commissioned
    and made available within the National Health Service (NHS)
    throughout England and Wales. The mission statement for
    NICE is that it “contributes to better health around the world
    through the more effective and equitable use of resources”.
    In 2005 NICE was revised to include reviews of public health
    interventions, and its mandate was expanded to include quality
    standards for the English social care sector (English Health and
    Social Care Act of 2011). Now renamed the National Institute
    for Health and Care Excellence, NICE operates as a statutory
    independent special health authority in England and Wales.
    Commissioning bodies of the NHS are required to observe its
    recommendations. Guidance can be used by the NHS, local
    authorities, employers, voluntary groups, and anyone else
    involved in delivering care or promoting well-being.

    NICE recommendations are respected elsewhere in the
    UK, but are not mandatory; in Scotland NICE recommen-
    dations are published after further review by NHS Quality
    Improvement Scotland (for health services issues) and by NHS
    Health Scotland (for public health recommendations). NICE
    recommendations are respected worldwide, including by the
    European Commission and by national governments; NICE
    International is a section of NICE established to meet non-UK
    needs (e.g., evaluating rural health programs in China).

    An independent committee including lay representation
    advises on priorities for NICE consideration but final deci-
    sions on topics referred to NICE are made by the Department
    of Health. When making recommendations to the NHS on
    which services (e.g., treatments) should be provided routinely,
    it calculates the cost-effectiveness of treatment for each quality-
    adjusted life year (QALY) of health gain purchased.

    NICE publications include guidance on 374 interventional
    procedures, 270 technology appraisals, 162 clinical guide-
    lines, and 43 public health topics. From this latter group, some
    examples include:
    l Prevention of cardiovascular diseases (2010) – provides

    evidence of effectiveness of population-based prevention
    programs as more effective than programs aimed at high-
    risk groups.

    l Alcohol dependence and harmful alcohol use (2011) –
    summarizes all NICE guidance; designed to inform mem-
    bers of the public as well as health professionals.

    l Preventing type 2 diabetes through population and com-
    munity interventions (2011) – provides guidance to gov-
    ernment departments, the commercial sector, health
    service organizations, and non-governmental organiza-
    tions on integration of public policy to prevent obesity, and
    reduce diabetes prevalence and complications.

    l Preventing uptake of smoking by children and young peo-
    ple (2008) – document to advise local health service com-
    missioners; identifies target populations, reviews campaign
    messages, and provides recommendations for the mass
    media and retailers.

    l Promoting mental well-being at work (2009) – guidance
    aimed at employers; reviews evidence in the field and rec-
    ommends strategic approaches by firms, opportunities to
    promote well-being and assess risk, and systems of flexible
    working.

    l Preventing unintentional injuries among under-15s in the
    home (2010) – reviews evidence and makes recommenda-
    tions to local authorities and related agencies on training
    an appropriate workforce, advises government to fund cur-
    ricula development, and indicates to the NHS appropriate
    surveillance and treatment services.
    NICE is often criticized (especially by the pharmaceuti-

    cal industry) for the time taken to carry out investigations of
    new treatments. It is also criticized by relatives of patients with
    “glamorous” conditions (e.g., cancer) for not approving drugs
    that might extend life by only 4–6 weeks, and perhaps approv-
    ing instead new psychiatric therapies. The current government
    has recently sought to overrule some of these NICE recommen-
    dations in England. However, NICE methods and recommen-
    dations are held in high repute, within the UK and beyond.

    BOX 15.8 The UK’s National Institute for Health and Care Excellence (NICE)

    NICE as an independent body to promote “national
    guidance on promoting good health and preventing and
    treating ill-health”. NICE produces guidance in three
    areas:

    l public health – guidance for those working in the NHS,
    local authorities and the wider public and voluntary sector
    on promotion of good health and the prevention of disease

    l health technologies – guidance on use of new and
    existing medicines, treatments and procedures within
    the NHS

    l clinical practice – guidance on appropriate treatment
    and care within the NHS of people with specific dis-
    eases and conditions.

    NICE guidelines are recommended practices with the
    objective of reducing ineffective practices. During 2007,
    guidelines were issued on topics including asthma, derma-
    titis, caesarean section, chronic obstructive lung disease,
    depression (in children and adults), eating disorders, fertil-
    ity, contraception, multiple sclerosis, post-traumatic stress
    disorder, and diabetic foot care (Box 15.8).

    by the American Medical Association as a response to
    findings of high rates of injury and death from iatrogenic
    disease in the USA, the NPSF promotes research into
    human error among health care providers, seeking ways
    to reduce the frequency and effects of medical error,
    such as misdiagnosis, medication errors, and mistakes
    during procedures. Website: http://www.npsf.org/au/

    l Joint Commission on Accreditation of Healthcare
    Organizations (JCAHO) – Originating in 1917 by the
    American College of Surgeons, it began accrediting
    hospitals in 1918. It developed in 1953 as the JCAHO,
    becoming a national voluntary accreditation organiza-
    tion focusing mainly on hospitals. Its mandate was broad-
    ened in 1987 and, as of 2007, had accredited more than
    15,000 health care organizations. Accreditation is man-
    datory for Medicare and Medicaid payment. The JCAHO
    is changing its approach from standards-based assess-
    ment every 3 years to one of reviewing performance data
    quarterly as a continuous surveillance activity for risk
    reduction. Website: http://www.jointcommission.org/

    The New Public Health

    The USA has a number of government and independent
    organizations dedicated to improving quality in health care
    systems. The CDC and the Institute of Medicine of the US
    National Academies of Science play active roles in promot-
    ing research quality and methods of CQI in the US health
    care system. Canada is also very active in this regard, hav-
    ing national and provincial institutes for the evaluation of
    clinical effectiveness and clinical guidelines, and so too are
    European countries (Box 15.9).

    PUBLIC HEALTH LAW

    Public health workers need knowledge of government
    structure and public health legislation as basic to their pro-
    fessional work to understand their responsibilities, powers
    and liabilities. Law consists of a system of rules, regula-
    tions, and orders that govern the behavior of individuals
    and of society. Law represents the consensus of a society, as
    enacted by an elected legislature, put into effect by the exec-
    utive branch of government, and interpreted by the courts
    as need be from time to time. The legislative and execu-
    tive branches are separate under the US Constitution, but
    the two are united in the parliamentary system (Box 15.10).
    The authority, responsibility, and power to provide for and
    protect the public health are basic functions of a sovereign
    government, which may be delegated to another level of
    government (higher or lower) or even a non-governmental
    agency. The constitution of a sovereign government states
    explicitly or implicitly that responsibility, but accepted
    practice and court decisions (i.e., the common law) define
    the powers of the national, state, or local government to
    monitor and protect the health of its citizens.

    In the USA, national legislation is enacted under the
    powers of the federal government, namely to regulate inter-
    state commerce and the power to tax and spend for the
    general welfare. State legislation is enacted under the basic
    power of the state to protect the health, welfare, and safety
    of its citizens. Under these federal and state powers, a wide
    range of health legislation and regulations is enacted affect-
    ing public health, labor, and occupational health and safety,
    environmental controls, public welfare, and the financing
    of health services, agriculture, food, drugs, cosmetics, and
    medical devices. Public health law relies on a wide range of
    constitutional, statutory, administrative, and judicial deci-
    sions in both civil and criminal actions. Appropriation of
    funds is a legal act of legislative bodies to achieve objec-
    tives directly or indirectly by financial incentives.

    Categorical programs may be directed to specific issues
    such as combating TB and promoting immunization or for
    work to combat NCDs such as diabetes, or in improving
    standards of facilities, and in providing health care services.
    The regulatory, enforcement, policing, and punitive func-
    tions of public health laws have evolved over many decades
    and in many countries lack clear definition. In the USA,

    801Chapter 15 Health Technology, Quality, Law, and Ethics

    In federal nations, political authority is divided between two
    autonomous sets of governments, one national and the other
    subnational. Both operate directly with the people in their juris-
    diction based on a constitutional division of power between
    the national government, which exercises authority over the
    whole national territory, and state or provincial governments
    with independent authority within their own territories. The
    constitution is the supreme law of a country. It sets out the
    divisions of governmental powers including statutory authority,
    administrative, natural resources, and taxation between federal
    and state levels of government.

    A federal legislature or congress makes the law of the land,
    but is subject to rulings of a Supreme Court as are state and
    local governments. State or provincial governments in a fed-
    eral system have functions set out in the Constitution. They
    also have elected legislatures, and executive branches with
    taxing, regulatory, and punitive powers. Local governments
    for county, municipal, or city governments also have dele-
    gated taxing and regulatory powers including those of public
    health.

    Canada, the USA, Brazil, Australia, India, and Argentina
    are organized on a federal basis. Federal countries also include
    Austria, Germany, Malaysia, Mexico, Nigeria, Switzerland, and
    Venezuela. Russia is called a federation. Usually there is some
    overlapping or shared powers between national and state con-
    stitutions, legislatures, and court systems, and public agencies,
    taxing powers and regulatory functions, such as in interstate
    commerce and emergency response to natural or other disasters.

    In a unitary government system, most or all of the governing
    power resides in a centralized government. This contrasts with
    a federal system. In unitary systems the central government

    commonly delegates authority to subnational units and chan-
    nels policy decisions down to them for implementation.
    A majority of nation-states are unitary systems. They vary greatly.
    The UK includes England, Scotland, Wales, and Northern
    Ireland, each with legislatures, but the Westminster Parliament
    in London maintains national powers. In health, each of the four
    member entities of the UK conducts a National Health Service
    with autonomy but common features. The national government
    may delegate certain powers to self-governing regions/local
    authorities, and there is a growing tendency to devolve various
    governmental functions such as health to regional authorities.
    More than 150 countries are unitary states, including France,
    Italy, Spain, China, and Japan.

    In both forms of government, local authorities are estab-
    lished under state law with governance by councils elected
    by the people, with taxing and regulatory powers within the
    state or provincial laws, with a high degree of autonomy but
    within state regulation, standards, and financial support. Local
    authorities have major responsibilities in public health such as
    in sanitation, licensing, and regulation of businesses and zon-
    ing, as well as many other areas, including social welfare.

    BOX 15.10 Legal Structure of Federal and Unitary Countries

    efforts are being made to update and reform laws in the pub-
    lic health sector. In 1988, the Institute of Medicine (IOM) in
    the USA (the Future of Public Health) called for codifica-
    tion of public health law as essential for the public good,
    while questioning the soundness of certain US public health
    laws. More recently, the Model State Emergency Health
    Powers Act in the USA, the Quarantine Act in Canada, and
    the revised International Health Regulations (2007) have
    sought to update century-old legislation. The revised inter-
    national regulations provide for a global approach to con-
    trol the spread of epidemics and public health emergencies
    while minimizing disruption to international activities such
    as travel, trade, and economics.

    A combination of the regulatory, persuasive, and fund-
    ing approaches is widely used in public health in control of
    communicable and non-communicable diseases, in improv-
    ing standards of facilities, and in providing health services.
    The regulatory, enforcement, policing, and punitive func-
    tions of public health are important in health promotion and
    assurance of health care. The taxing power of government is
    essential for public health to ensure that adequate facilities

    and access to care are available to all members of the com-
    munity, especially those in financial need and thus at greater
    risk for disease.

    Medical officers of health and their staff have legal
    authority to issue formal orders for health protection of
    the public. Situations which require court proceedings are
    referred to the justice system. Situations that may require
    enforcement by court proceedings are referred to the justice
    system. Laws may be enacted to fund public health activi-
    ties, whether provided by public health authorities or by
    acting through official or non-official agencies or providers.
    Public health authorities, namely medical officers of health,
    have the legislative power to issue orders to individuals or
    businesses where there is a threat to the health of the public
    such as food establishments. Administrative resources are
    needed to enforce laws, such as through the FDA and the
    Environmental Protection Agency, which come under the
    aegis of the Department of Health and Human Services.
    Other departments such as Agriculture, Education, or inter-
    departmental agencies (e.g., Homeland Security), also are
    key to public health activities, such as in disaster situations.

    Other intergovernmental activities may require special leg-
    islation to empower, finance, and promote their cooperation,
    such as in the case of establishing an authority to manage
    long-term efforts to clean up a contaminated river or basin,
    which involves the cooperation and coordination of many
    local authorities.

    Health protection of individuals and communities may
    require legal action to detain a person in order to prevent
    the spread of a reportable communicable disease, to protect
    a mentally ill patient, or to restrain a violent person. Such
    powers should be used as a last resort if voluntary compli-
    ance and education fail, and where the danger to the commu-
    nity or the individual is sufficient to convince a court of the
    public need to override the personal liberty of an individual.
    An example is a 2007 case of a person with MDR-TB who
    was taken into custody on arrival for compulsory treatment
    after traveling across the Atlantic Ocean on a commercial
    airline, against the specific instructions of his physician, thus
    endangering fellow passengers. Outbreaks of measles in the
    UK (2006–2007) and in Israel via imported cases among
    ultraorthodox Jews or conservative protestant groups in the
    Netherlands, with transmission among religious people who
    tend not to immunize their children, led to pressure by health
    authorities to immunize those placed at risk by such contacts
    at weddings or other large public events.

    However, these measures are currently used less than
    voluntary isolation or quarantine and placarding homes for
    reportable infectious diseases such as measles. Powers are
    essential in extreme cases where refusal to comply with
    public health measures endangers others. Such powers
    should have been used more vigorously in the early years
    of the AIDS epidemic at a time when individual rights took
    precedence over protection of the population, including
    vulnerable high-risk groups. The severe acute respiratory
    syndrome (SARS) epidemic of 2003 led to sequestering
    hospital staff in Toronto, Canada, for lengthy periods to
    prevent spread of the disease, and subsequent influenza
    pandemic threats have raised questions as to whether hos-
    pital personnel should be required to be immunized to pro-
    tect patients and their families from onward transmission
    of dangerous infections.

    Recent cases in the USA, the UK, and Norway dem-
    onstrate the responsibility of governments to protect the
    public from incidents of violence by dangerous, mentally
    disturbed individuals who carry out mass killings. In Nor-
    way, 69 people, mostly teenagers, were killed by a radical
    ideologue while many others sustained serious injuries; and
    in the USA, Islamic terrorists at the Boston Marathon killed
    three and seriously injured more than 200 others; a 20-year
    old fatally shot his mother then killed 20 children and six
    adult staff members at Sandy Hook elementary school in
    Newtown, Connecticut, before killing himself; and an army
    psychiatrist who had become an increasingly devout and

    The New Public Health

    radicalized Muslim psychiatrist shot and killed 13 people
    and injured more than 30 others in a Texan army base.
    Background checks and other restrictions on gun sales are
    an important public health and political issue, especially in
    the USA. The wide availability of guns, including military-
    style assault weapons, presents a serious danger for impul-
    sive or planned mass killings.

    Public health has generally evolved with greater reli-
    ance on health promotion through voluntary cooperation of
    a patient or community than on compulsion. Enabling leg-
    islation may permit a local authority to fluoridate its water
    supply, but the enactment of local legislation and funding to
    implement it may also require a public referendum. In some
    states in the USA and in Israel, fluoridation of community
    water supplies is mandatory, which is also part of the health
    promotion approach to public health.

    Appropriation of public funds to promote public health is
    through approval by the legislature for a specified program.
    Provision of public funds may take the form of categorical
    grants for specified services, such as immunization, prenatal
    care, school health, or specific disease management such as
    TB control, cancer control, or AIDS education. Programs may
    be designed to promote certain types and quality of services,
    such as the Hill–Burton Act, which provided federal grants
    for hospital construction in the 1950s to 1970s, conditioning
    these grants on certain requirements concerning hospital licen-
    sure and hospital planning. Such legislation has a “carrot and
    stick” effect of attracting lower levels of government to seek
    such funding but also requiring them to accept the conditions
    and regulations that accompany the grants. The Canadian fed-
    eral government’s cost sharing of provincial health (hospital
    and medical) insurance programs is based on federal criteria
    requiring public administration, portability between provinces,
    accessibility without payment, comprehensiveness, and ban-
    ning extra billing by physicians (see Chapter 13).

    Public funds are also appropriated in the context of
    legislated programs in which people are entitled to the ser-
    vices defined in the appropriation legislation, such as in the
    amendments to the Social Security Act providing Medicare
    and Medicaid programs, or national health insurance legis-
    lation in many countries. These and their regulations spell
    out categories and specified entitlement benefits.

    Legislation and court decisions to protect the rights of
    the individual are part of public health. Public health law
    is meant to protect individuals and communities from
    potential abuse, of both individual and community human
    rights, as in the US Bill of Rights. Enforcement of public
    health law may infringe on individual rights by enforcing
    sanitation, food and drug safety, and supervision of res-
    taurants and catering firms. Laws may allow restriction of
    civil rights, such as rarely used mandatory treatment of a
    person with a dangerous contagious disease or mental ill-
    ness. Freedom of religion may come into conflict with other

    Chapter 15 Health Technology, Quality, Law, and Ethics

    laws in public health where restrictive practices may deny
    the use of publicly supported health facilities, as when a
    religiously affiliated hospital may refuse an abortion proce-
    dure in a case of rape. Religious practices or other personal
    beliefs may endanger others in the community, such as in
    the refusal to immunize children so that an imported infec-
    tious disease may spread among non-immunized people
    and even affect those who are immunized, as occurs with
    imported measles cases even when domestic transmission
    of the disease has previously been eradicated. General legis-
    lative provisions applied to public health forbid misleading
    or unethical advertising. Legislative provisions may also
    ban advertising for products, such as tobacco, which are
    legal but may be harmful to health. These laws affect public
    health but are provisions in other statutes such as the regu-
    lation of business enterprises. Legislation may also make
    smoking in public places illegal, with fines for offenders
    and operators of places such as public bars.

    Since the 1973 US Supreme Court decision of Roe v.
    Wade, the law has allowed women to seek safe and legal
    abortion. This remains a highly controversial political issue
    in the USA and several other countries. The potential con-
    flict between community and individual interests and rights
    is part of the dynamics of public health law and public health
    practice. The issues involved are complex and highly politi-
    cized, and often involve ethical distinctions where “the great-
    est good for the greatest number” may limit the legitimate
    rights of individuals and vice versa. The PPACA in 2010 is a
    fundamental legislative initiative, upheld by the US Supreme
    Court to become the law of the land. It will bring millions of
    Americans into regulated health insurance with many protec-
    tive elements to prevent abuse by private insurance company
    through arbitrary exclusions or limitations.

    The legal aspects of public health are vital to its opera-
    tion and are increasingly complicated by ethical issues, and
    by public and political debate. Health protective legislation
    and regulation for sanitation of food, water, and air are fun-
    damental to public health, as is the control of drugs, cosmet-
    ics, vaccines, and biologicals, the manufacture of devices,
    and the licensing of health personnel and facilities. Limi-
    tations of legal suits (torts) against manufacturers of vac-
    cines proved to be a successful measure in the USA with
    the introduction of the National Vaccine Injury Compensa-
    tion Program (NVICP) in 1988. This is funded by a modest
    surcharge tax collected from vaccine manufacturers. It pro-
    tects both public and private interests while providing a fair
    compensation system to ensure patients’ rights but without
    jeopardizing immunization to prevent widespread disease,
    and also protects manufacturers from litigation with high
    legal costs and excessive compensation awards by the jury
    system. Promoting healthy behavior through the prudent
    use of the legal system of regulation and taxation is increas-
    ingly utilized to protect the health of the population. This is

    803

    widely applied in promoting road safety, in tobacco control
    measures regarding banning of advertising, high taxes on
    alcohol, and banning smoking in public places including
    restaurants and bars.

    Environmental Health

    There is growing concern by the public and by governments
    over climate change, global warming, air and water pollu-
    tion, and other noxious and harmful industrial and com-
    mercial processes. Environmental laws affecting the public
    health include legislation on clean air, clean water, toxic
    substances, solid waste control, and other noxious sub-
    stances. Non-compliance with the legislative provisions can
    result in prosecution in the civil or criminal courts or both.

    Infringement of public health laws and regulations may
    lead to criminal action as an increasingly common method
    of sanction. While such violations may not be seen as “truly”
    criminal and may be treated in the courts as misdemeanors,
    they can lead to fines or even jail. Such cases are increas-
    ingly being addressed seriously in the judicial system.

    The CDC, in 1999, defined 10 great achievements
    of public health of the twentieth century. These achieve-
    ments are identified as control of infectious disease, motor
    vehicle safety, fluoridation of drinking water, recognition
    of tobacco use as a health hazard, immunization, decline
    in deaths from coronary heart disease and stroke, safer
    and healthier foods, healthier mothers and babies, family
    planning, and safer workplaces (Goodman et al., 2006).
    Of the 10 great achievements in the twenty-first century
    (2001–2010) identified by CDC, seven of the 15 leading
    causes of death (largely NCDs) resulted in a decline in the
    age-adjusted death rate in the USA from 881.9 per 100,000
    population in 1999 to 741.0 in 2009. This decline was a
    result of a combination of supportive laws and legal tools
    at the local, state, and federal levels. In other industrial-
    ized countries similar legislation has led to equal or greater
    achievements in public health over the past century.

    Public Health Law Reform

    Public health law is scattered through many legislative stat-
    utes and administrative documents which developed his-
    torically. Efforts to codify public health law may contribute
    to greater understanding and enforceability of the many
    separate pieces of legislation (Box 15.10). Such reform
    will enhance understanding in the legislative, judicial, and
    administrative branches of government as well as in busi-
    ness, non-governmental organizations, and the community.
    Box 15.11 suggests topics for model public health consoli-
    dation or compendia for states. The principles of this formu-
    lation may also apply to other countries at the national and
    state or provincial levels.

    ETHICAL ISSUES IN PUBLIC HEALTH

    The field of public health includes a wide range of activities
    and professional disciplines, ranging from health promo-
    tion to disease protection, epidemiology to environmental
    health, and financing to supervision or provision of clinical
    care. Each of these disciplines works within systems that
    face ethical dilemmas, and public health workers’ under-
    standing and motivation within the ethical guidelines of
    their professions and roles are important in their training
    and practice conduct. Ethical frameworks have evolved in
    part as the result of bitter experience with ethical failures
    which were later recognized and affect public health stan-
    dards of practice for future generations (Box 15.12).

    Ethics in health are based on the fundamental religious
    and humanistic values and concepts of a society. If the prin-
    ciple of saving a life is valued above all other considerations
    (i.e., Sanctity of Life or Pikuah Nefesh) (see Chapter 1),
    then all measures available are to be used, irrespective of
    the condition of the patient or the cost. If sickness and death
    are seen as acts of God, possibly as punishment for sin, then
    prevention and treatment may be considered to be interfer-
    ing with the divine will, and the ethical obligation may be
    limited to relief of suffering. Humanism balances these two
    ethical imperatives: saving of life and relief of suffering.
    Materialistic political philosophies may view health care as
    primarily a function to preserve health for economic pros-
    perity and social well-being. Secular humanism adopted
    many of the religious precepts of the worth and rights of the
    individual and these have become part of the standards of
    law and ethics in modern secular societies.

    The role of society in protecting the health of the popula-
    tion grew during the nineteenth century with the sanitation

    The New Public Health

    movement, while medical care became an effective part of
    public health during the twentieth century. The astonishing
    successes of public health during the past century increased
    life expectancy in the high-income countries by some 30
    years, mostly through improved living conditions and
    health protection, as well as societal and medical advances
    to make care available to all. In the 1970s the Lalonde con-
    cept that individual behavior was one of the key determi-
    nants of health (see Chapter 2) placed much of the onus
    of illness and its prevention on the individual, but fostered
    health promotion as an essential component of public health
    theory and practice. All these points of view are involved
    in the ethical issues of the New Public Health (Box 15.13).

    Resources for health care are limited even in indus-
    trialized countries, so that priority setting and judicious
    allocation of scarce resources are always issues. Money
    spent on new technology with only marginal medical
    advantages is often at the expense of well-tried and proven
    lower cost techniques to prevent or treat disease. The
    potential benefits gained by the patient from more and
    more interventions are sometimes very limited in terms
    of length or quality of life. These are difficult issues when
    the physician’s commitment to do all to preserve the life
    of the patient conflicts with the patient’s concept of qual-
    ity of life and his or her right to decline or terminate heroic
    measures of intervention. Many health systems use clini-
    cal guidelines that are mandatory for a health facility or a
    doctor in the clinic. Preparation for surgery requires a sig-
    nature from the patient to consent to the procedure being
    carried out, careful preoperative procedures to ensure that
    the correct organ is addressed, antiseptic preparation of
    the site, and checking that all instruments are accounted

    for. The checklist approach is well established for care
    in many settings and protects the patient from neglect or
    faulty follow-up, such as in the management of hyperten-
    sion and diabetes.

    The suffering that a terminally ill patient may endure
    during radical treatment, which may prolong life by only
    hours or days, clashes with the physician’s ethical obli-
    gation to do no harm to the patient. The ethical value
    of sustaining the life of a terminally ill patient suffering
    extensively is an increasing medical dilemma. The issue is
    even more complex when economic values are included in
    the equation. There are potential conflicts among the eco-
    nomic issues, the role of the physician in preserving life,
    the physician’s obligation to do no harm, the felt needs
    of the patient and his or her family, and the needs of the
    community as a whole. The complex issues involved in
    the “right to die” and end-of-life care raise many ethical
    and legal questions for the patient, the family, society, and
    caregivers.

    The state represents organized society and has, among
    its responsibilities, a duty to promote healthful conditions
    and to provide access to health care and public health

    BOX 15.13 Study and Practice of Public Health Ethics

    Ethics is a branch of philosophy that deals with distinctions
    between right and wrong, with the moral consequences of
    human actions. The ethical principles that arise in epidemio-
    logical practice and research include:
    l informed consent
    l confidentiality
    l respect for human rights
    l scientific integrity.

    “As a field of study, public health ethics seeks to understand
    and clarify principles and values which guide public health
    actions. Principles and values provide a framework for decision
    making and a means of justifying decisions. Because public
    health actions are often undertaken by governments and are
    directed at the population level, the principles and values
    which guide public health can differ from those which guide
    actions in biology and clinical medicine (bioethics and medical
    ethics) which are more patient or individual-centered.

    As a field of practice, public health ethics is the application
    of relevant principles and values to public health decision mak-
    ing. Public health ethics inquiry carries out three core functions:

    (1) identifying and clarifying the ethical dilemma posed,
    (2) analyzing it in terms of alternative courses of action and their

    consequences, and
    (3) resolving the dilemma by deciding which course of action

    best incorporates and balances the guiding principles and
    values.” (CDC, 2001)

    services. The conflict between individual rights and com-
    munity needs is a continuous issue in public health. Appli-
    cation of accepted public health measures for the benefit of
    some people in society may require applying an interven-
    tion to everyone in a community or a nation. The major-
    ity thus are subject to a public health activity to protect a
    minority, without designating which individual’s life may
    be saved. Furthermore, a society may in special cases need
    to restrict individual liberties to achieve the goal of reducing
    disease or injury in the population. Raising taxes on alco-
    hol and tobacco products, mandatory speed limits, driving
    regulations, and seat belt usage laws are examples of pub-
    lic health interventions that interfere with individual liberty
    but protect individuals, and thereby the community at large,
    from potential harm.

    Many public health measures originally criticized as
    interventions in private rights are generally accepted as
    essential for health protection and promotion to reduce
    the risk of disease in the population. Chlorination of com-
    munity water supplies is a well-established, effective, and
    safe intervention to protect the public health. Fluoridation
    of drinking water to prevent tooth decay in children means
    that other people are also drinking the same fluoridated
    water, which is of less direct benefit to them. Fortification
    of foods with vitamins and minerals is also a cost-effective
    community health measure with advocates and opponents.
    The addition of folic acid to food as the most effective way
    to prevent neural tube defects in newborns is an intervention
    mandated by the US FDA since 1998.

    Confidentiality to assure the right of the individual to
    privacy involves ethical issues in the use of health infor-
    mation systems. Birth, death, reportable conditions (not
    all reportable diseases are infectious), and hospitalization
    data are basic tools of epidemiology and health manage-
    ment. The use of detailed individual data is needed for
    case-finding and follow-up activities which are vital to
    good epidemiological management of diseases, includ-
    ing STIs. However, caution is needed in data use to avoid
    individual identification that could be used punitively,
    for example, in denial of access to health insurance for
    smokers, alcoholics, or AIDS patients because health
    damage may be attributable to a self-inflicted risk factor.
    Increasingly, however, reporting is also mandatory for
    physical or sexual abuse and criminally linked injuries
    as essential for the protection of individuals at risk or the
    general public from serious harm.

    Individual and Community Rights

    The protection of the individual’s rights to privacy, and free-
    dom from arbitrary and harmful medical treatments, proce-
    dures, or experiments, may come up against the rights of the
    community to protect itself against harmful health issues.
    This conflict comes into much of what is done in public

    http://www.cdc.gov/od/science/phec/

    http://www.cdc.gov/od/science/phec/

    806

    health practice, which has both an enforcement basis in law
    and practice and a humanitarian and protective aspect based
    on education, persuasion, and incentives. Society permits
    its governments to act for the common good, but sets limits
    that are protected by the courts and administrative appeal
    mechanisms.

    Society has the right to legislate the side of the road
    on which one is permitted to drive, the speed permitted,
    the wearing of seat belts, and the non-use of alcohol or
    drugs before driving or cell phones while driving. Offend-
    ers may be punished by significant fines or jail and are
    subject to strong educational efforts to persuade them to
    comply. Similarly, the community must ensure sanitary
    conditions and prevent hazards or nuisances from bother-
    ing neighbors or the public. Society must act to protect the
    environment against unlawful contamination or poisoning
    of food, drugs, the atmosphere, the water supply, or the
    ground.

    Enforcement is thus a legitimate and necessary activ-
    ity of the public health network to protect the community
    from harm and danger to health. Table 15.6 shows topics
    where individual rights and responsibilities predominate,
    and a second set of rights that are the prerogative of the
    community to protect its citizens against public health haz-
    ards. Sometimes the issues overlap and sometimes come to
    political, advocacy, or legal action, so that court decisions
    are needed to adjudicate precedents for the future.

    The AIDS epidemic in the 1980s and 1990s raised a
    host of public health, ethical, and issues. Management of
    the AIDS epidemic is in some respects in conflict with the
    long-established role of society in contacting and quarantin-
    ing people suffering from transmissible diseases. It is not
    acceptable or feasible in modern society to isolate HIV car-
    riers. But failure or delay of public health authorities even
    in the late 1980s to close public bathhouses in New York
    and other cities in the USA, where exposure to multiple
    same-sex partners promoted transmission of the infection,
    could be interpreted as negligence. During the 1980s, the
    gay community in the USA centered its concern that HIV
    testing would be used in a discriminatory manner. AIDS was
    initially addressed as a civil liberties issue and not as a pub-
    lic health problem. Screening, reporting, and case contact
    follow-up were seen as an invasion of privacy and proved
    counterproductive by increasing resistance to and avoidance
    of testing. Protection of privacy and an educational approach
    were adopted as most feasible and acceptable. International
    opinion and national court decisions have emphasized the
    right to privacy with decriminalization of non disclosure of
    HIV status to sex partners (UNAIDS 2013).

    The AIDS epidemic and public anxiety about contract-
    ing AIDS through casual contact reinforced the need for
    public education on safe sex. This has been raised as an
    ethical issue because such education may be construed as
    condoning teenage and extramarital relations. The issue of

    The New Public Health

    HIV screening of pregnant women in general or in high-risk
    groups took on a new significance with the findings that
    treatment of the pregnant woman reduces the risk of HIV
    infection of the newborn, and that breastfeeding may be
    contraindicated. This issue is arising anew in the context of
    using the HPV vaccine for preteen girls to prevent the sexu-
    ally transmitted infection, which is also controversial, and in
    the USA this vaccination will be mandatory for school entry.

    A pre-eminent ethical issue in public health is that of
    assuring universal access to services, and/or the provision
    of services according to need. An important ethical, politi-
    cal, and social issue in the USA in the twenty-first century
    is how to achieve universal access to health care. The soli-
    darity principle of socially shared responsibility for fund-
    ing universal access to health care is based on equitable
    prepayment for health care for all by nationally regulated
    mechanisms through place of work or general revenues of
    government. A society may see universal access to health
    care as a positive value, and at the same time utilize incen-
    tives to promote the use of services of benefit to the indi-
    vidual, such as hospital care, immunization, and screening
    programs. Some services may be arbitrarily excluded from
    health insurance, such as dental care, although this is to the
    detriment of children and a financial hardship for many.
    Strategies for program inclusion are often based on his-
    torical precedent rather than cost-effectiveness or evidence.
    While efforts are being made to include more children in the
    program, the Medicaid system in the USA defines eligibil-
    ity at income levels of 185 percent of the poverty line, thus
    excluding a high percentage of the working poor. Health
    is also a political issue in countries with universal health
    systems where funding may be inadequate or patient dis-
    satisfaction common.

    Choices in health policy are often between one “good”
    and another. Limitations in resources may make this issue
    even more difficult in the future, with aging populations,
    increasing population prevalence of physical disabilities,
    and rapid increases in technology and its associated costs.
    For example, the UK’s NHS at one point refused to provide
    dialysis to people over the age of 65. When computed tomog-
    raphy was first introduced, Medicare in the USA refused to
    insure this service as an untested medical technique. Owing
    to a lack of facility resources such as incubators and poor
    prospects for the survivors, the Soviet health system con-
    sidered newborns as living only if they weighed over 1000 g
    and survived for more than 7 days. Those under 1000 g, who
    would be considered living by other international definitions,
    would be placed in a freezer to die. At the opposite extreme,
    many western medical centers use extreme and costly mea-
    sures to prolong life in terminally ill patients, preserving life
    temporarily but often with much suffering for the person and
    at great expense to the public system of financing health care.

    In many countries, such as those in the former Soviet
    system of health care, spending for hospital services, in

    some cases grossly in excess of need, is accompanied by
    a lack of adequate funds for primary care or adding new
    vaccines to the immunization program for children. The
    majority of Americans have health insurance which increas-
    ingly includes preventive care services, but a substantial

    percentage lack such coverage which limits their access to
    routine preventive care. The Affordable Care Act brings an
    improvement in coverage and inclusion of preventive care
    with incentives (see Chapters 10 and 13). In many coun-
    tries, including in Europe, delay in updating immunization

    808

    programs may be due to a lack of funding or to delays
    in professional or governmental acceptance of “new”
    vaccines.

    The closure or amalgamation of hospitals involves dif-
    ficult decisions and is a source of friction between central
    health authorities, the medical professions, and local com-
    munities. Health reforms in many industrialized countries,
    such as reducing hospital bed supplies and managed care
    systems promoting cost containment and reallocation of
    resources, raise ethical and political issues often based on
    vested interests such as private insurance systems, hospi-
    tals, and private medical practitioners.

    Where there is a high level of cumulative evidence from
    the professional literature and from public health practice
    in “leading countries” with a strong scientific base and case
    for action on a public health issue, when does it become bad
    practice or even unethical public health practice to ignore and
    fail to implement such an intervention? Such ethical failures
    occur frequently and widely. For example, is it “unethical”
    not to fortify grain products with folic acid, and salt with
    iodine? Should there be a recommended European immu-
    nization program; should milk be fortified with vitamin D;
    should vitamin and mineral supplements be given to women
    and children; should all newborns be given intramuscular
    vitamin K routinely? Other examples include the issues of
    fluoridation of water supplies and opposition to genetically
    modified crops or generic drugs in African countries. These
    issues are continuously debated and the responsibility of
    the trained public health professional is to review the inter-
    national literature on a topic and formulate a position based
    on the cumulative weight of evidence. It is not possible to
    wait for indisputable evidence because in epidemiology and
    public health this rarely occurs. This is another reason for
    guidelines established by respected agencies and profes-
    sional bodies, which are free from financial obligations to
    vested interest groups, being essential for review of the evi-
    dence which continues to accumulate on many issues thought
    to have been resolved or which reappear repeatedly despite
    strong evidence of effectiveness and public health benefit.

    Tragic Deviations in Public Health Ethics

    In the nineteenth century the germ and miasma theories both
    produced enormous gains in public health. The biomedical
    paradigm addressed alleviation of disease risk or manifest
    disease; the health paradigm addressed the improvement of
    social and environmental conditions for reducing disease.
    During the early part of the twentieth century, a segment of
    the social hygiene movement promoted ideas of Social Dar-
    winism or racial improvement by sterilization of mentally
    ill, retarded, and other “undesirable” people.

    The dominant biomedical model of public health and
    medical professionals adopted policies of eugenics in
    Sweden, the USA, and Canada, leading to policies and

    The New Public Health

    programs to force the sterilization of mentally handi-
    capped or mentally ill patients. This distorted a socially
    oriented concept of public health. This euthenasia policy
    was adapted to a racially oriented policy with horrendous
    policies of mass murder in the name of racial purity as a
    public health policy in Nazi Germany with the near-total
    support and participation of a highly Nazified medical
    profession, and used in murder, by gassing or planned
    starvation, of half a million “undesirables” under the
    eugenics “T-4” program administered from Hitler’s head-
    quarters. Although this program was stopped after parental
    and Church protests in Germany, the methods used were
    adopted in newly occupied countries and for concentra-
    tion camps organized for the mass extermination of Jews,
    Gypsies, and others in the Holocaust.

    The eminent historian Sir Richard Evans (Regius Pro-
    fessor of History at Cambridge University), in his classic
    The Third Reich at War, wrote:

    “At the heart of German history in the war years lies the mass
    murder of millions of Jews in what the Nazis called ‘the final
    solution to the Jewish question in Europe’. This book provides a full
    narrative of the development and implementation of this policy of
    genocide, while also setting it in the broader context of Nazi racial
    policies toward the Slavs, and toward Gypsies, homosexuals, petty
    criminals and ‘asocials’. … For many years, and not merely since
    1933, the medical profession, particularly in the field of psychiatry,
    had been convinced that it was legitimate to identify a minority of
    handicapped as ‘a life unworthy of life’, and that it was necessary
    to remove them from the chain of heredity if all the many measures
    to improve the German race under the Third Reich were not to be
    frustrated. Virtually the entire medical profession has been actively
    involved in the sterilization programme, and from here it was but a
    short step in the minds of man to involuntary euthanasia.”

    The twentieth century was replete with mass murders,
    executions, and genocide, with nationalistic, ideological,
    and racist motives perpetrated by fascist, Stalinist, and
    radical xenophobic political or religious movements when
    gaining governmental power by election or by revolution,
    in some cases applying common public health terminol-
    ogy and concepts to uses of genocide and ethnic cleansing
    (Box 15.14).

    An outline of genocides of the past 100 years is seen
    in Box 15.15. These include the Turkish genocide of the
    Armenians in 1917 followed by horrific genocides in which
    many millions of people were killed, carried out under the
    communist regime of the Soviet USSR in the 1920s and
    subsequently, in the People’s Republic of China under
    Chairman Mao in the 1950s, and by the Khmer Rouge in
    Cambodia in the 1980s, and in the wars resulting from the
    breakup of the Yugoslav Republic in the 1990s.

    The human and national cost of genocide lasts for gen-
    erations. The hatred and fear may wane but the trauma goes
    deep. It lasts with the victims and their descendants, but

    Chapter 15 Health Technology, Quality, Law, and Ethics

    also with the perpetrating country and its culture. The Nazi
    Holocaust has had downstream effects in public health in
    the German-speaking countries which last to the present
    time, seven decades since the events took place. The long-
    term damage done to public health in Germany and Austria
    is described in Box 15.16.

    The Nuremberg Doctors’ Trial in 1946–47 convicted
    many leading Nazi physicians of crimes against humanity
    and resulted in severe punishments including hanging or
    long prison terms. This trial was a seminal event in estab-
    lishing the ethical standards required for medical research
    and human rights. However, many in the medical profession
    aligned with these horrors remained leading figures in the

    BOX 15.14 Values and Ethical Principles of Public
    Health

    l Sanctity of human life.
    l Individual human rights – liberty, privacy, protection

    from harm.
    l Solidarity – sharing the burden of promoting and main-

    taining health.
    l Beneficence – reduce harm and burdens of disease and

    suffering.
    l Non-malfeasance – do no harm.
    l Proportionality – restriction on civil liberties must be

    legal, legitimate, necessary, and use the least restrictive
    means available.

    l Reciprocity principle – public responsibility to those who
    face disproportionate health and social burden.

    l Transparency principle – honest and truthfulness in the
    manner and context in which decisions are made must
    be clear and accountable.

    l Precautionary principle – decision makers have a general
    duty to take preventive action to avoid harm even before
    scientific certainty has been established.

    l Failure to act – public health officials and policy mak-
    ers have a duty to act and implement preventive health
    measures demonstrated to be effective, safe, and benefi-
    cial to population health. Failure to enforce public health
    regulations with resulting disease or deaths may consti-

    l Trust between the many stakeholders in health.
    l Reasonableness – decisions should be evidence based

    and revised based on new evidence.
    l Responsive to needs and challenges as they may be

    German medical community, one even being elected to head
    the World Medical Association, then discussing the Helsinki
    Declaration of Ethics in Biomedical Research, before being
    forced to resign. The Nuremberg Trials and the subsequent
    Helsinki Declaration laid the fundamentals of biomedical
    ethics for the following generations, regulated by require-
    ments of ethical procedures and institutional research board
    approvals for funding, conducting, and publishing research
    involving human subjects (Table 15.7).

    The United Nations Convention on Prevention and Pun-
    ishment of the Crime of Genocide (UNGC) of 1948 defines
    acts committed with intent to destroy, in whole or in part,
    members of a national, ethnical, racial, or religious group
    as crimes against humanity. This convention specifies that
    incitement to genocide is itself a crime against humanity.
    Legal action should focus on state-sanctioned incitement
    as a recognized early warning sign. The UNGC defines
    genocidal acts to include the following as punishable under
    international law:

    l genocide
    l conspiracy to commit genocide
    l direct and public incitement to commit genocide
    l attempt to commit genocide
    l complicity in genocide.

    The reappearance of genocide in the late twentieth cen-
    tury in the Balkans and Rwanda, and in the twenty-first cen-
    tury by Sudanese in Darfur, highlights genocide as a public
    health concern and its prevention as a public health and
    international political responsibility. Incitement to genocide
    is a crime against humanity and was the basis for the trials
    and convictions of leaders of the Rwandan Tutsi tribe, as
    well as inciters to ethnic violence and the political leaders
    and perpetrators of mass murders in the former Yugoslav
    Republic. The threat and practice of genocide are still pres-
    ent, whether in the murderous raids of Sudanese Janjaweed
    militias in Darfur and South Sudan, the threats of genocide
    by Iran and associated terrorist organizations against Israel
    and Jews in general, or the killing of Christians in northern
    Nigeria and Egypt, of Muslims in Burma/Myanmar, and
    others. Incitement to genocide is now common as part of
    international discourse.

    Genocide represents the most extreme assault on the right
    to life and respect for life. In the twentieth century, an esti-
    mated 200 million people perished through genocide. Totali-
    tarian dictatorships, past wars, and ideologies of exclusiveness,
    ethnic purity, and religious fundamentalism increase the risks
    for genocide. Perpetrators use dehumanizing, demonizing,
    and delegitimizing hate language to desensitize or intimidate
    bystanders and to mobilize, order, and instruct followers.

    Genocide prevention requires international surveillance
    networks for monitoring and reporting incitement and hate
    language in the media, textbooks, places of worship, and the
    Internet, which should monitor and identify their sources

    The New Public Health810

    Eugenics was a movement within the “social hygiene” con-
    cept of the early part of the twentieth century. It was widely
    promoted to reduce births among mentally ill and handi-
    capped people in some states in the USA and was upheld
    in decisions of the Supreme Court. It was also practiced
    in Canada and Sweden. This idea was promoted by Hitler
    in Mein Kampf and adopted by the Nazi Party, which was
    legally elected to office in 1933 and began to implement it.
    Organized massacres of mentally ill and handicapped chil-
    dren and adults led to practices of organizing various modes
    of killing, including gas chambers, which were applied in
    concentration camps and in the Holocaust murder of 6 mil-
    lion Jews and millions of others.

    Genocide represents the most extreme assault right to life
    and respect for life. In the twentieth century, an estimated 200
    million have perished from genocide. Totalitarian dictator-
    ships, past war and defeat, ideologies of exclusiveness, ethnic
    purity, and religious fundamentalism increase risks for geno-
    cide. Perpetrators use dehumanizing, demonizing, and delegit-
    imizing hate language to desensitize or intimidate bystanders
    and to mobilize, order, and instruct followers.

    Human Experimentation

    Human experimentation has been a subject of great concern
    since the Nazi and Imperial Japanese armed forces’ experi-
    ments on prisoners and concentration camp victims during
    World War II. The Nuremberg Trials set forth standards of
    professional responsibility to comply with internationally
    accepted medical behavior (Table 15.7).

    The Helsinki Declaration was first adopted by the
    World Medical Assembly in 1964, and amended in 1975,
    1983, 1989, and 1996. It delineates standards of medical
    experimentation and requires informed consent from sub-
    jects of medical research. These standards have become an
    international norm for experiments, with national, state,
    and hospital Helsinki committees regulating research pro-
    posals within their jurisdiction. Funding agencies require
    standard approval by the appropriate Helsinki committee
    before considering any proposal, with informed consent on
    any research project.

    The Tuskegee experiment (Box 15.17) was a grave and
    tragic violation of medical ethics, but in the context of the
    1930s was consistent with widespread and institutionalized
    racism. It provides an important case study which has reper-
    cussions until the present time in suspicion of public health
    endeavors, particularly among the African American com-
    munity in the USA.

    811Chapter 15 Health Technology, Quality, Law, and Ethics

    In the German context the social–ecological health paradigm
    can be traced back to the late eighteenth and early nineteenth
    centuries when the country was a loose alliance of kingdoms
    or princedoms lagging behind the economic, cultural, and
    political developments in England and France. Ensuring popu-
    lation health was seen as the obligation of the state, while the
    family was responsible for caring for the health and well-being
    of its members. Organized health care and health maintenance
    was seen in the framework of Medizinische Polizey, as a model
    of the health systems. Leading scholars in law and medicine
    shared a normative perspective of promoting a healthy life-
    style (known as dietetics), and provision of shelter, food, and
    spiritual aid in asylums for the sick and disabled, or in private
    homes the for wealthy.

    In the second half of the nineteenth century evidence from
    medical statistics and overwhelming practical experience indi-
    cated that widespread poverty was the critical factor explain-
    ing high rates of typhus or cholera epidemics in lower social
    classes among children and industrial workers. A social health
    movement fought for healthier living and working conditions,
    education, and democracy. The movement’s prominent lead-
    ers were Salomon Neumann, a physician pioneer in medical
    statistics, and Rudolf Virchow, the renowned pathologist and
    outspoken political activist.

    Between 1890 and 1930 the conceptual framework of pub-
    lic health was defined as “social hygiene” or “health science”,
    an interdisciplinary field to conduct scientific research, aca-
    demic teaching, and community-based activities aiming at the
    promotion of individual and collective health and the preven-
    tion of disease. In the 1920s the field was highly developed and
    pioneering the modern academic public health.

    Social hygiene was a general framework open to different
    definitions. A group of academic teachers and publishing scien-
    tists sharing the social–ecological paradigm, among them a high
    proportion of German Jews, wanted to continue the social reform
    strategy and to strengthen local communities to take an active role
    in the formulation and implementation of health policies.

    Public health activists sharing the biotechnological disease
    paradigm favored a more focused approach aiming at the con-
    trol of disease through medical care. Although there was no

    supportive evidence, in the late nineteenth century a racial
    eugenic movement emerged widely in Europe and the USA.
    A conceptual model derived from the disease paradigm postu-
    lated racial factors to explain disease. A healthy population was
    assumed to be “free” of “racially contaminated” individuals and
    inferior groups. Health-related public policy was supposed to
    eliminate racially “unclean” members, e.g., by forced steriliza-
    tion or murder. This was a central theme in Hitler’s Mein Kampf
    and was enacted as basic policy by the Nazi Party in Germany
    as a fundamental ideological basis of racial theory and public
    health.

    When the Nazis were legally elected in Germany in 1933,
    and later seized power in Austria, this policy provided fertile
    ground to open the door to euthanasia, leading to mass mur-
    der. This was implemented in the well-organized, medically
    directed execution of mentally and physically handicapped
    Germans and others in psychiatric facilities. This provided a
    working model for the industrialized murder of 6 million Jews
    in the Holocaust and millions of gypsies, homosexuals, com-
    munists, and others.

    It took only 10 years to eradicate a 200-year tradition of
    German socially oriented public health grounded largely in the
    political philosophy of human rights and social justice. Most
    of those advocates were exiled or murdered. Many of the aca-
    demic medical leaders after World War II remained in key posi-
    tions in the German public sector for decades.

    In contrast to many other countries, the two wealthy
    German-speaking countries, with over 90 million people,
    have few academic public health resources. In there is only
    one German School of Public Health, and a small number of
    institutes, far fewer in Austria than in Germany. More than half
    a century has passed since the Nazi period and the populations
    of these two countries are slow to build a new socially oriented
    public health system.

    BOX 15.16 The Rise, Fall, and Slow Recovery of German Public Health

    Ethics in Public Health Research

    The border between practice and research is not always
    easy to define in public health, which has as one of its
    major tasks the surveillance of population health. This
    surveillance is mostly anonymous but relies on individu-
    ally identifiable data needed for reportable and infec-
    tious disease control as well as for causes of death, birth
    defects, mass screening programs, and other special dis-
    ease registries. It may also be necessary to monitor the
    effects of chronic disease, for example, to ascertain repeat
    hospitalizations of patients with congestive heart failure
    to assess the long-term effects of treatment, and the effects

    of strengthening ambulatory and outreach services to sus-
    tain chronic patients at a safe and functional level in their
    own homes.

    Hospitalizations, immunizations, and preventive care
    practices (e.g., Pap smears, mammography, and colonosco-
    pies) are all part of the New Public Health. Impact assessment
    of preventive programs may require special surveys and are
    important to assess smoking and nutritional status and other
    measures of health status and risk factors. Every effort must be
    made to preserve the anonymity and privacy of the individual
    but in some cases, where the disease is contagious, case contact
    is crucial. This can entail identifying people who attended an

    1946–47

    The voluntary consent of a human subject is absolutely essential, with the exercise of free power of
    choice without force, fraud, deceit, duress, or coercion

    Experiments should be such as to bear fruitful results, based on prior experimentation and the natural
    history of the problem under study. They should avoid unnecessary physical and mental suffering

    The degree of risk should not exceed the humanitarian importance of the experiment

    Persons conducting experiments are responsible for adequate preparations and resources for even the
    remote possibility of death or injury resulting from the experiment

    The human subject should be able to end his participation at any time

    The scientist in charge is responsible to terminate the experiment if continuation is likely to result in
    injury, disability, or death

    potential benefits outweigh the risks, with careful assessment of risks, where the privacy and integrity
    of the individual is protected, and where the hazards are predictable. Publication must preserve the
    accuracy of research findings

    Each human subject in an experiment should be adequately informed of the aims, methods,
    anticipated benefits, and hazards of the study. Informed consent should be obtained, and a
    statement of compliance with this code

    Clinical research should allow the doctor to use new diagnostic or therapeutic measures if they
    offer benefit as compared to current methods

    In any study, the patient and the control group should be assured of the best available methods.
    Refusal to participate should never interfere with the doctor–patient relationship. The well-being

    The general distinction between research and practice
    has to do with the intent of the activity. Clinical research uses
    experimental methods to establish the efficacy and safety of
    new interventions or unproved interventions; many drugs
    and procedures in common use have never been subjected

    to randomized controlled trials. In practice, many methods
    are devised that are held to be effective and safe by expert
    opinion and documented as such. Researchers comparing
    HIV or hepatitis B transmission rates among intravenous
    drug users not using needle-exchange programs would be

    rent standards, by giving needles to the experimental group

    and withholding them from the control group. The scientific
    justification of an experiment must be made explicit and
    justifiable. Clinical equivalence is a necessary condition
    of all clinical and public health research and provision of
    standard of care treatment to control groups is a minimal
    requirement for most research ethics boards. Determination
    of the standard, and whether it should be place, time, and
    community specific, is an area of ongoing controversy.

    In 1996 a US Public Health Service study, supported by
    the NIH and WHO, compared a short course of zidovudine
    (AZT) to a placebo given late in pregnancy to HIV-positive
    women in Thailand, measuring the rate of HIV infection
    among the newborns. The experiment was terminated when
    a protest editorial appeared in a prominent medical journal.
    This study confirmed previous findings that AZT given dur-
    ing late pregnancy and labor reduced maternal–fetal HIV
    transmission by half. When a study shows clearly positive
    results, it should be discontinued and reported so that the
    findings can be applied generally. The findings indicated
    that AZT should be used in developing countries, and the

    BOX 15.17 The Tuskegee Experiment

    The Tuskegee experiment was carried out by the US Public
    Health Service between 1932 and 1972. It was meant to fol-
    low the natural course of syphilis in 399 already infected
    African American men in Alabama and 201 uninfected men.
    The men were not told that they were being used as research
    subjects. The experiment had been intended to show the
    need for additional services for those infected with syphilis.
    However, when penicillin became available, the research-
    ers did not inform or offer the men treatment, even those
    who were eligible when drafted into the army in 1942. The
    experiment was stopped in 1972 as “ethically unjustified”
    when the media exposed it to public scrutiny.

    The case is considered unethical research practice
    because, even at the time it was conducted, it did not pro-
    vide the patients with available care and their well-being
    was put aside in the interest of the descriptive study. A similar
    experiment was conducted by the US Public Health Service
    in cooperation with the Guatamala Ministry of Health dur-
    ing the 1960s, in which syphilis was actually given to sol-
    diers, prisoners, and others by sexual contact with prostitutes
    known to have the disease, but the study was terminated
    when it was discovered by a public health historian and
    reached public attention in the USA.

    In 1997, President Bill Clinton apologized to the survi-
    vors and families of the men involved in the experiment on
    behalf of the US government. The Tuskegee experiment is
    the source of lingering widespread suspicion in the African
    American community to the present time.

    manufacturers agreed to make it available at reduced costs.
    The result has been a major success in helping with more
    recent medications to reduce maternal–fetal transmission in
    many places in Africa with help from GAVI, and a slowing
    of the spread of HIV/AIDS-related deaths.

    Public health may face the challenge of pandemic influ-
    enza, such as avian flu, with decisions regarding the allocation
    of vaccines, treatment of massive numbers of patients arriv-
    ing at hospitals in acute respiratory distress with very limited
    resources available, coping with sick or absent staff, and many
    other issues requiring not only individual life and death situ-
    ations, but mortality en masse. The ethical questions will be
    replaced by struggles to cope with such situations. Preparation
    for such potential catastrophic events will be a challenge to
    public health organizations and the health system in general.

    An outstanding case of a breach of ethics in public health
    research occurred with the “Wakefield effect”, as described
    in Chapter 4 and Box 15.18.

    Ethics in Patient Care

    Ethical issues between the individual patient and health
    care provider are important in the New Public Health. A
    doctor is expected to use diligence, care, knowledge, skill,
    discretion, and caution in keeping with practice standards
    accepted at the time by responsible medical opinion and
    to maintain the basic medical imperative to do no harm
    to the patient. Patients have the right to know their condi-
    tion, available alternatives for treatment, and the risks and
    benefits involved. They also have a right to seek alterna-
    tive medical opinions, but this right is not unlimited, as any
    insurance plan or health service may place restrictions on
    payment for further opinions and consultation without the
    agreement of a primary care provider.

    Health care has a responsibility beyond that of the pay-
    ment of health service bills and individual care by a physi-
    cian, in institutions, or through services in the community
    or the home. The contract for service is becoming less
    between an individual physician and his or her patient, and
    more among a health system, its staff, and the client. This
    places a new onus on the physician to ensure that patients
    receive the care they require. Conversely, the US provider
    often faces the dilemma of knowing that a patient may not
    access needed services because of a lack of adequate health
    insurance.

    Sanctity of Life Versus Euthanasia

    The imperative to save a life is an important ethical and prac-
    tical issue in health care. Advocates of physician-assisted
    suicide (euthanasia) argue for the right of the patient to die
    with dignity when the illness is terminal and the individual
    is suffering excessively. This is not a medical decision alone,
    and is an agonizing issue for society to address. The Nazi
    euthanasia program and its human experiments provided

    The New Public Health814

    In 1998, The Lancet, published an article by a number of well-
    known researchers headed by Dr Andrew Wakefield. The article
    reported on 12 cases of autistic children and alleged to show a
    connection to immunization with the MMR (measles–mumps–
    rubella) vaccine.

    The immediate effect of this “revelation” was widespread
    alarm over the MMR vaccine and a fall off in immuniza-
    tion coverage by measles-containing vaccines in the UK
    and elsewhere with many mothers refusing to have their
    child vaccinated due to a “risk of autism”. As a result,
    measles epidemics occurred in the UK and in many other
    countries, with measles again becoming endemic in many
    parts of Europe, especially England and France.

    After a long series of investigative journalism in the British
    press, the article came under scientific scrutiny and withdrawal
    of many of the coauthors but a consistent insistence by the lead
    author of its authenticity.

    Investigation by British medical authorities later found
    Dr Wakefield guilty of medical negligence and the UK
    General Medical Council withdrew his license to practice
    medicine. The coauthors were found to have been credulous
    and insufficiently vigilant in agreeing to coauthorship of the
    paper. In 2000, 12 years after the original publication, The
    Lancet formally withdrew the article.

    The effect of this fraudulent scientific publication was a
    serious loss of credibility of immunization in general and
    especially regarding the MMR vaccine, one of the greatest life
    savers in public health technology.

    The return of measles in Europe to large scale epidemics
    with frequent international transmission furthered the loss of

    confidence of mothers in immunizations and public health.
    Measles-containing vaccines were particularly strongly
    affected owing to the publicity given to the Wakefield case.
    The journal editors could be seen as irresponsible for failing
    to ensure the scientific integrity of lead authors and coauthors,
    and the journal for failing to retract a fraudulent article sooner
    than 12 years after the first publication.

    In other public health issues, single publications of findings
    of small sample and poorly assessed studies published in haste
    without adequate inquisitive review occur with great frequency.
    The electronic media often include unscientific opinion blogs
    which appear larger than life which provoke great anxiety over
    accepted and successful public health interventions such as flu-
    oridation or folic acid fortification of flour, with unsubstantiated
    claims that they cause cancer, asthma, and other ill-effects.

    The interface between ethics, law, and science in pub-
    lic health requires continuous sensitivity to the downstream
    effects of “shouting fire in the theater”.

    BOX 15.18 The Wakefield Effect

    the direst of warnings to societies of what may follow when
    the principle of the sanctity of the individual human life is
    breached. The issue, however, returned to the public agenda
    in the 1980s and 1990s as advances in medical science have
    allowed the prolongation of human life beyond all hope of
    recovery. Legislation in the Netherlands, the USA (“assisted
    suicide” in the states of Washington, Oregon, and Montana),
    and northern Australia has legally sanctioned euthanasia
    with various safeguards in a variety of circumstances, such
    as long-term comas or terminal illnesses.

    Doctors, patients, relatives, and health care organiza-
    tions need clear guidelines, orientation, procedures, legal
    protection, and limitations where failure to take utmost
    steps to “save” the patient by intubation, resuscitation, or
    transplantation may cause legal jeopardy. Even though a
    distinction can be drawn theoretically between permitting
    and facilitating death, in practice, doctors in intensive care
    units face such decisions regularly where the line is often
    blurred. Hospital doctors routinely go to extreme mea-
    sures to prolong the life of hopeless cases. Such decisions
    should not be considered for economic reasons alone, but in

    practice the costs of care of the terminally ill will be a driv-
    ing force in debate of the issue. Living wills allow a patient
    to refuse heroic measures such as resuscitation, with “do
    not resuscitate” standing orders and assignment of power of
    attorney to family members to make such decisions. Fam-
    ily attitudes are important, but the social issue of redefining
    the right of a patient to opt for legal termination of life by
    medical means will be an increasingly important issue in
    the twenty-first century.

    The Imperative to Act or Not Act in Public
    Health

    As in other spheres of medicine and health, in public health
    the decision whether to intervene on an issue is based on
    identification and interpretation of the problem, the poten-
    tial of the intervention to improve the situation, to do no
    harm, and to convince the public and political levels of the
    need for such intervention along with the resources to carry
    it out. This process requires patience and a longer time-
    frame than many other fields in health.

    Chapter 15 Health Technology, Quality, Law, and Ethics

    Some interpretations of ethics in health consider that the
    only purpose for which power can be rightfully exercised
    over any member of a democratic community, against his
    will, is to prevent harm to others. But this is not a dictum
    that is applied to public health, which is obliged to act to
    protect the public health in so many spheres such as food
    and drug safety and environmental health, on a spectrum
    that extends to banning smoking in public places, mandat-
    ing food fortification, and many other areas of civil society.

    Failure to act is an action, and when there is convincing
    evidence of a problem that can be alleviated or prevented
    entirely by an accepted and demonstrably successful inter-
    vention, then the onus is on the public health worker to
    advocate such action and to implement it as best as possible
    under the existing conditions. Failure to do so is a breach of
    “good standards of practice” and could be unethical. Iner-
    tia of the public health system in the face of evidence of a
    demonstrably effective modality such as adoption of state-
    of-the-art vaccines or fortification of flour with folic acid
    to prevent birth defects would come under this categoriza-
    tion and may even constitute neglect and unethical practice.
    This is not an easy categorization, because there is often
    disagreement and even opposition to public health interven-
    tions, as was the case with opposition to vaccination long
    after Jenner’s crucial discovery of this procedure in the late
    eighteenth century. It is also true today with opposition to
    many proven measures such as fluoridation or fortification
    of basic foods. Box 15.19 shows the ethical standards of the
    APHA in 2006.

    The use of ethical and high standards of practice in pub-
    lic health (Box 15.20) requires an ideological commitment
    to the advancement of health standards and use of best prac-
    tices of international standards to the maximum extent pos-
    sible under the local conditions in which the professional is
    working. This is not an easy commitment as there is often
    dispute and outright hostility to public health activities, in
    part because of ethical distortions of great magnitude in the
    past. But this is an optimistic field of activity because of the
    great achievements it has brought to humankind. Prepara-
    tion for disasters and unanticipated health emergencies in
    addition to addressing current issues is a vital part of the
    New Public Health and our ethical and professional com-
    mitments.

    SUMMARY

    In order to maintain and improve standards of care, health
    systems need quality assurance and technological assess-
    ment as part of their ongoing operation. Poor-quality care
    is costly in terms of iatrogenic diseases and prolonged or
    repeated hospitalization. If innovations such as endoscopic
    surgery are not introduced, then longer hospital stays are
    needed for the same operation, wasting the patient’s time
    and productivity, while utilizing expensive health care

    815

    resources, and incurring the risks associated with more
    invasive surgery.

    Health care is provided by people, as well as by insti-
    tutions with a range of devices and equipment. The people
    providing care, more than the technological facilities, set the
    quality of care. Nevertheless, progress on the technological
    side of medical care is vital to the continuing development
    of the field. Modern medications, monitoring equipment,
    laboratory services, and imaging devices have made enor-
    mous contributions to advances in medical care. Appropriate

    l Public health should address principally the fundamen-
    tal causes of disease and requirements for health, aiming
    to prevent adverse health outcomes.

    l Public health should achieve community health in a way
    that respects the rights of individuals in the community.

    l Public health policies, programs, and priorities should be
    developed and evaluated through processes that ensure
    an opportunity for input from community members.

    l Public health should advocate and work for the empow-
    erment of disenfranchised community members, aiming
    to ensure that the basic resources and conditions neces-
    sary for health are accessible to all.

    l Public health should seek the information needed to
    implement effective policies and programs that protect
    and promote health.

    l Public health institutions should provide communities
    with the information they have that is needed for deci-
    sions on policies or programs and should obtain the
    community’s consent for their implementation.

    l Public health institutions should act in a timely manner
    on the information they have within the resources and
    the mandate given to them by the public.

    l Public health programs and policies should incorpo-
    rate a variety of approaches that anticipate and respect
    diverse values, beliefs, and cultures in the community.

    l Public health programs and policies should be imple-
    mented in a manner that most enhances the physical and
    social environment.

    l Public health institutions should protect the confidential-
    ity of information that can bring harm to an individual or
    community if made public. Exceptions must be justified
    on the basis of the likelihood of significant harm to the
    individual or others.

    l Public health institutions should ensure the professional
    competence of their employees.

    l Public health institutions and their employees should
    engage in collaborations and affiliations in ways that
    build the public’s trust and the institution’s effectiveness.

    The New Public Health816

    Publication in peer-reviewed journals is a key part of the
    advancement in science and a vital part of the development
    of the scientific basis for public health practice. The process of
    publication should promote rigorous standards of high quality
    ethical research and the wide dissemination of their findings.
    Codes of practice for editors and publishers of peer-reviewed
    journals have been developed by both the Committee on
    Publication Ethics (COPE) (Rees, 2011) and the World
    Association of World Editors (WAME).

    Editors are subject to competitive pressures, and the over-
    arching metric of success is seen to be the impact factor, a
    measure of the frequency with which the “average article”
    in a journal has been cited in a particular year or period.
    Relevant, rigorous research of better quality will tend to be
    cited more frequently, and thus editorial strategies that look
    for quality and relevance in the given field will increase the
    impact factor. However, there can also be potential distort-
    ing factors. Publishing a highly controversial paper can result
    in high citation levels. Publishing studies which demonstrate
    negative findings may be less likely to attract large numbers
    of citations.

    Key issues relate to conflicts of interest, and the potential for
    advertising and sponsorship to distort editorial decision mak-
    ing (Gray, 2012). A particular concern has been the pernicious
    influence of the tobacco industry in sponsoring, frequently
    covertly, research which has aimed to confuse or obfuscate key
    findings linking second hand exposure to tobacco to adverse
    impacts on health. Similar tactics are used in other areas where
    health and commercial interests collide. Clear statements of
    potential conflicts of interest are essential. Journal owners must
    not interfere in the evaluation, selection, or editing of individ-
    ual articles, either directly or by creating an environment in
    which editorial decisions are strongly influenced.

    Other challenging areas are plagiarism and research mis-
    conduct. The latter is extremely difficult both to detect and to
    deal with, and requires close working between institutions and
    editors who may suspect professional misconduct. In cases of
    fraud, the publishing journal should withdraw the article in a
    timely fashion (see Box 15.18: The Wakefield Effect).

    There has been a rapid rise in open access publishing, in
    part underpinned by an ethical belief that research is a public
    good, and an increasing number of influential research funders
    now require that there should be unrestricted access to the
    published output of research. In addition, several publishers
    make their journals free to those in selected low-income coun-
    tries, promoting dissemination to those who might not other-
    wise afford them.

    In summary, publication in peer-reviewed journals remains
    a key method for establishing and progressing the evidence
    base for public health practice. The consequences of poor
    or frankly fraudulent science can have a substantial adverse
    impact both on health and on the use of resources. Editors must
    adhere to high ethical and professional standards and remain
    vigilant to avoid allowing external drivers to distort their deci-
    sion-making processes. They must strive to maintain integrity
    and high scientific standards to advance the field of public
    health practice (Smith, 2007).

    BOX 15.20 The Ethics of Publication in Public Health

    technology is a critical issue for international health, since
    the most advanced technology may be completely inappro-
    priate in a setting that cannot afford to maintain it or lacks
    the trained personnel to operate it, or where it comes in
    place of more vital basic primary care services. Technology
    assessment needs to be seen in the context of the country and
    its resources for health care.

    Ethical issues in public health are no less demanding
    than those related to individual clinical care. The rights of
    the individual and those of the community are sometimes in
    conflict. Technology, quality, the law, and ethics are closely
    interrelated in public health. Well-informed and sensitive
    analysis of all aspects of their development is a part of the
    New Public Health. The balance between individual and
    community rights is very sensitive and must be kept under
    continuous surveillance.

    The New Public Health is replete with technological
    and ethical questions, especially in a time of cost restraint,
    increasing technological potential, the public expectation

    of universal access to health care, and the assumption that
    everyone will live a healthy and long life. Health status has
    always been linked with socioeconomic status and, despite
    enormous gains, this remains true even in the most egalitar-
    ian countries. Expansion of market mechanisms, such as
    controlling the supply of hospital beds, doctors, and access
    to referrals, competition and incentives/disincentives in
    payment systems for hospital and managed care systems,
    contribute to a need for dynamic health policy management
    capacity. The New Public Health assumes a social responsi-
    bility for health for all, using community and personal care
    modalities as effectively as possible to achieve that overall
    goal.

    Learning Objectives

    Upon completion of this chapter, the student should be
    able to:
    1. Describe responsibility for and methods of assessing and

    regulating technological developments in health care;
    2. Describe methods of health facility accreditation and

    peer review;
    3. Describe the concept of total quality management;
    4. Identify and discuss ethical and legal issues in national

    health systems;
    5. Apply ethical considerations to health issues in his or

    her home setting.

    INTRODUCTION

    Management of a production or a service system requires
    attention to the quality of personnel as much as to the system
    in which they work. Their motivation and sense of participa-
    tion, the scientific and technological level of the program,
    and the legal and ethical standards of individual providers
    and of the system as a whole, are all important to the quality
    of care provided and equity of health status achieved.

    Quality is the result of input and process, and is measured
    by outcome or performance indicators as well as perception
    of the service by the patients, the staff, and the community
    as a whole. Input refers to the institutional and financial
    resources for education, human resources, supplies, medica-
    tions, vaccines, diagnostic capacity, and services available.
    Process refers to the use of those resources, including peer
    group expectations of professionalism. Outcomes generally
    include measures of morbidity, mortality, and functional sta-
    tus of the patient and the population. Defining and measuring
    achievements of national health objectives and targets, the
    methods of financing services, and the efficiency of organi-
    zation help to determine quality. Training, supply, and dis-
    tribution of health personnel are all determinants of access
    to and quality of care. Continuous and adequate availability
    of essential preventive, diagnostic, and treatment services,
    as well as accountability and internal methods of promoting
    standards, are all elements of the quality of a health service

    771

    for the individual, the population as a whole, and groups
    within the population with special needs.

    The content and standards of service are assessed
    through organized review by professional peers within
    an institution, and from outside. Peer review within an
    institution and external evaluation by accreditation or
    governmental inspection, based on cumulative evidence
    and the recognized current “state of the art”, contribute
    to accountability and improved quality of care. Continu-
    ous quality improvement (CQI) among health care teams
    and organizations includes regular practice assessments,
    evidence gathering, remediation, and re-evaluation, which
    will be discussed later in this chapter. The perception of
    the services by the community, along with the knowledge,
    attitudes, beliefs, and practices of health, are all vital to
    improvement of health status.

    Health-related technology is also in a continuing state
    of change. Systematic review and absorption of new scien-
    tific knowledge, technology, and innovations are essential
    to promote and renew health care methods. Public health
    serves in a regulatory role to assure high-quality care to the
    individual and the community. New technology, whether in
    the form of diagnostic procedures, new drugs, devices, or
    vaccines, or new types of health personnel, requires evalu-
    ation for effectiveness and appropriateness to the system.

    Technology assessment also involves epidemiological and
    economic aspects of effectiveness. Failure to continuously
    monitor developments and to assimilate those that are demon-
    strably successful is an ethical and management failure which
    tragically costs many millions of lives from preventable dis-
    eases yearly, such as in delayed adoption of well-proven vac-
    cines or tobacco restriction legislation. This is due to political
    failure even more than professional weakness, and constitutes
    one of the saddest ethical dilemmas of public health: failure
    to convince policy makers of the prime importance of health
    promotion and disease prevention in the health sector.

    Ethics and law in public health reflect the values of a
    society. They inevitably evolve as they face dramatic social,
    economic, demographic, and political changes; new health
    challenges; and new technological and scientific possibili-
    ties for improving health. Ethics are the foundation of the
    value systems of a society and thus of its health concepts.

    772

    Biblical sources articulated values of the Ten Command-
    ments, Sanctity of Human Life, Improve the World, along
    with the Hippocratic Oath of physicians to “do good and do
    no harm”. Modern definitions of public health and bioethics
    emerged from lessons learned from the horrors of eugenics
    and genocide in the twentieth century with humanistic pre-
    cepts of “Universal Human Rights” and “Health for All” in
    the recent era (see Chapters 1 and 2).

    The law is both permissive and restrictive. It sets the basic
    responsibilities, powers, and limitations of public health prac-
    tice, with legislation and court decisions. Innovations in the
    technology of medical care and public health are powerful
    forces contributing to increased longevity, quality of life, and
    economic growth, but they also bring challenges to imple-
    mentation impeded by additional costs of the health system
    and slow adaptation in countries with the greatest need.
    These are challenges to national and international political,

    The New Public Health

    organizational, and economic systems to address health with
    the full potential for saving lives. Determining standards of
    “good practice” is a continuing process with the rapid devel-
    opment of new knowledge, technology, and experience.

    The law is a dynamic process involving old and new
    legislation, court decisions, and new issues not previously
    faced, often following rather than anticipating public health
    issues. Public health has had both positive and negative ethi-
    cal experiences and continues to face new issues with chang-
    ing population needs, technology, science, and economics.

    Chapter 15 Health Technology, Quality, Law, and Ethics

    vaccination by Jenner (1796), to the dramatic innovations of
    the end of the twentieth century (Table 15.1). The pace of
    innovation is rapid, creating the need for regulation, quality
    control, and technology assessment.

    National governments are responsible for assuring that
    pharmaceuticals, biological products, food, and the environ-
    ment are regulated to protect the public. In some countries,
    these responsibilities are divided among ministries of trade,
    industry, commerce, health, and environment. In a federal
    system of government, there may be a division of responsi-
    bility among federal, state, and local government, but with
    the national government often providing national standards
    and leadership in this area.

    Government regulation and control are meant to protect
    the public health. The US Food and Drug Administration
    (FDA) is responsible for enforcing the Food, Drug and Cos-
    metic Act, the Fair Packaging and Labeling Act, sections of
    the Public Health Services Act relating to biological prod-
    ucts for control of communicable diseases, and the Radiation
    Control for Health and Safety Act. The FDA is a Division
    of the Department of Health and Human Services (DHHS).
    State governments have the authority to supervise pharma-
    cies and their products, which may be marketed across dif-
    ferent states. All national governments have departments
    responsible for conducting supervision of food, drugs, and
    medical devices, often relying on international standards.

    Drugs and devices include all drugs, diagnostic prod-
    ucts, blood and its derivatives, biologicals, veterinary
    medicines, and medicated premixed animal products. All
    manufacturers and distributors are required by law to reg-
    ister these products with the national authority in order to
    be allowed to market or import them. All countries need to
    govern the food, drugs, vaccines, and cosmetics regulated
    for production, importation, marketing, and use within
    their jurisdiction. Organizations within each government
    must be responsible for assuring the consumer that foods
    are pure (unadulterated) and wholesome, safe to eat, and
    produced under sanitary conditions; that drugs and medical
    devices are safe and effective for their intended uses; that
    cosmetics are safe and made from appropriate ingredients;
    and that labeling is truthful, informative, and not deceptive.

    National authorities such as the FDA, under legisla-
    tion and regulations, govern both domestic and imported
    products. They establish and enforce standards, or adopt
    external agency standards as a “gold standard”, meaning
    that products meet high standards of safety and efficacy.
    The FDA also monitors and inspects contents manufactur-
    ing standards under good manufacturing practices (GMPs),
    which includes regular accreditation of a manufacturer’s
    facilities, staffing, planning, and monitoring capacity. Test-
    ing of products is carried out to assess safety, potency, and
    toxicity using accepted reference laboratory procedures as
    published in the compendium Official Methods of Analysis
    of the Association of Official Analytical Chemists.

    773

    When federal, state, or local investigators, sometimes
    known as consumer safety officers, detect through labora-
    tory monitoring or observe conditions that may result in a
    public health hazard, and violation of food and drug laws
    and regulations, they issue a written report to the manufac-
    turers with recommendations for correcting the conditions.
    In more blatant cases, the authorities may issue urgent recall
    or seizure orders for products in violation of standards con-
    stituting a danger to public health, such as contaminated
    products, lead-painted children’s toys, or contaminated
    foods causing foodborne disease outbreaks, which occur
    not infrequently in imported and domestically produced
    foods in the USA. The Los Angeles County Department of
    Health inspects restaurants regularly and places a promi-
    nent placard in the window giving a grade A, B, or C to
    the restaurant for sanitation and safety. Those given D rat-
    ings may be closed until specified faults are eliminated, or
    a restaurant may be closed permanently. State governments
    require restaurants to list calorie and salt content of foods
    on their menus as part of the public health efforts to reduce
    obesity.

    Supervision of food standards may also fail, as occurred
    in Israel in 2004 when total absence of vitamin B1 in a soy-
    based baby formula imported from Germany resulted in
    three deaths and permanent brain damage to other infants
    due to severe beriberi. This episode led to criminal charges
    in 2008 of negligence resulting in death against the own-
    ers of the company that imported or produced the foods and
    staff members of the Ministry of Health. Animal foods in
    2007 and infant milk products imported from China in 2008
    were found to be contaminated with melamine, which was
    meant to mimic protein content but was toxic in combination
    with other chemicals used. The infant formula caused seri-
    ous illness in some 300,000 Chinese babies and six deaths.

    The FDA and its counterparts in each country are
    responsible for regulation of:

    l food – foodborne illness, nutritional content, labeling,
    dietary supplements

    l drugs – prescription drugs and generics, over-the-counter
    products

    l medical devices – pacemakers, stents, contact lenses,
    hearing aids

    l biologics – vaccines, blood products
    l animal feed and drugs – for livestock, pets
    l cosmetics – safety, labeling
    l radiation-emitting products – cell phones, lasers, micro-

    waves
    l combination products.

    New drugs and biological products for human use are
    required to pass rigorous review before approval for mar-
    keting is granted. Applications are submitted by the manu-
    facturer or sponsor with acceptable scientific data including
    test results to evaluate the safety and effectiveness of the

    774

    product for the conditions under which it is being offered.
    All manufacturers of drugs are required to be registered
    with the FDA and to meet its requirements for each drug
    produced and marketed, including the reporting of adverse
    reactions and labeling criteria. Manufacturers are required
    to operate in conformity with current GMPs, which include
    stringent control over manufacturing processes, personnel
    training, computerized operations, and testing of finished
    products. The FDA publishes guidelines to help manufac-
    turers to familiarize themselves with current standards. The
    United States Pharmacopoeia, National Formulary, and
    WHO Model Formulary 2008 are the official listings of
    approved products.

    Medical devices are also regulated by the FDA. Thou-
    sands of products for health care purposes require premarket
    approval, ranging from basic articles such as thermometers,
    tongue depressors, and intrauterine devices (IUDs), to more
    complex devices such as cardiac monitors, pacemakers,
    breast implants, and kidney dialysis machines. These prod-
    ucts are subject to controls of GMPs, labeling, registration
    of the manufacturer, and performance standards.

    Monitoring for efficacy and potential hazards has
    been strengthened since the 1970s as a result of find-
    ings of long-term carcinogenic and mutagenic effects of
    estrogens, and toxic effects of chloramphenicol on bone
    marrow. The drug thalidomide, widely used as an antin-
    auseant and sleeping pill for pregnant women in Europe,
    Canada, and Australia in the 1960s, was not approved by
    the US FDA. This drug was found to cause large numbers
    of serious birth deformities leading to its being banned in
    most countries. Controls of blood and blood products have
    been strengthened since the transmission of human immu-
    nodeficiency virus (HIV), hepatitis B, and hepatitis C by
    contaminated blood products in the 1980s. The responsi-
    bility of this regulatory function is well illustrated by the
    1995 criminal conviction of several senior health officials
    in France for failing to stop the use of blood products con-
    taminated with HIV in the mid-1980s. Concern regarding
    possible carcinogenic effects of silicone breast implants
    led to legal action and greater controls of all implantable
    products. A balance between safety and well-regulated
    approval of new products requires a highly professional
    and motivated regulatory agency, well-developed proce-
    dures, and well-trained staff.

    The concepts of standardization of GMPs for pharma-
    ceutical products and written protocols for good medi-
    cal practice or good public health practice are accepted
    norms based on best available evidence of current scientific
    knowledge and experience. Recommended immunization
    schedules, water quality, ambient air standards, food fortifi-
    cation, and screening programs for early stages of diabetes
    are examples of accepted practice that have become rec-
    ommended standards of public health practice, paralleling
    qualitative measures developed in clinical care.

    The New Public Health

    APPROPRIATE HEALTH TECHNOLOGY

    The concept of intermediate technology pioneered by Dr
    Ernst Schumacher in the 1960s proposed the development
    of simple and inexpensive technology for developing coun-
    tries such as India to promote local economic development.
    Environmentally sustainable development and sources of
    energy, energy conservation, and reductions in toxic and
    harmful emissions are encouraged. In recent years ideas
    have included small loan systems for rural entrepreneurs in
    developing countries, and the use of simple cell phones for
    communication, farm produce marketing, cash transfers in
    remote areas without banking services, and many others.
    Now called appropriate technology, this topic has gained
    adherence in the health field in the search for low-cost and
    simple techniques for preventing and managing common
    illnesses.

    Appropriate technology is defined by the World Health
    Organization (WHO) as the level of medical technology
    needed to improve health conditions in keeping with the
    epidemiological, demographic, and financial situation of
    each country. All countries have limited resources and
    so must select strategies of health care and appropriate
    technology to use those resources effectively to achieve
    health benefits. Improved water pumps, solar energy, rain-
    water collection and water reservoirs, sanitary latrines,
    fly traps, insecticide-impregnated bed nets, biogas from
    animal waste, improved home cooking stoves, and many
    other simple devices can make enormous differences in
    local sustainable agriculture, economic growth, and living
    conditions. Cell phones are now used to monitor health
    conditions such as hypertension, diabetes control, weight
    and body mass index, and other non-communicable con-
    ditions, and to transmit imaging from remote areas to
    specialists in medical centers who can provide test read-
    ings online. Simple, affordable, portable information tech-
    nology can effectively support public health programs,
    even in resource-poor environments.

    The topics discussed in the growing literature and meet-
    ings of the International Society of Technology Assessment
    in Health Care represent the dynamic field of technology
    assessment. The issues range from economic evaluation
    of pharmaceuticals to modeling approaches, measures of
    quality of life, technology dissemination and impact, and
    outcomes measurement. The range of issues also includes
    finance and health insurance, health care in developing
    countries, informatics, telemedicine, technologies for the
    disabled, screening, and cost-effectiveness. Evaluations
    in the scrutiny of both high- and low-technology services
    based on a combination of clinical, epidemiological, and
    economic factors are necessary. As health costs rise, dis-
    abling conditions increase and populations age, medical
    innovation proceeds at a rapid rate, and both client and
    community expectations in health care continually rise.

    Chapter 15 Health Technology, Quality, Law, and Ethics

    In developing countries, the training and supervision of
    traditional birth attendants (TBAs) for prenatal preparation
    and normal deliveries are important ways to reduce maternal
    mortality in rural areas, as discussed elsewhere, and an impor-
    tant Millennium Development Goal (MDG) which will not
    be met by 2015. Community health workers (CHWs) in well
    supervised and supported programs are essential to provide
    preventive care to underserved rural poor populations with a
    defined package of services that can be tailored to meet spe-
    cific local needs, such as immunization, child growth moni-
    toring, nutrition counseling, and malaria and TB control.

    A major example of appropriate technology has
    been the WHO initiatives to promote national drug for-
    mularies (NDFs) as a consensus list of essential drugs
    that are sufficient for the major health needs of a coun-
    try, eliminating unnecessary duplication and combined
    products on the commercial market. The WHO calls on
    all member states to ensure the availability and rational
    use of drugs and vaccines, and supports states wishing
    to select an essential list of drugs for economic procure-
    ment. Assistance with drug regulatory agencies, legisla-
    tion, quality control, information, supply, and training is
    offered to help the member countries. Standard reference
    laboratories, the International Pharmacopoeia, and the
    WHO Drug Bulletin promote international standards and
    provide guidance to member states. The WHO Model List
    of Essential Drugs is a valuable tool to improve quality
    and cost management in national health systems.

    Cochlear implants are now routinely used for chil-
    dren with congenital or other loss of hearing, as well as in
    elderly people. In August 2013, a new cell phone applica-
    tion was announced which photographs the eye and can be
    used to diagnose cataracts, macular degeneration (AMD),
    and other eye pathology, for interpretation by experts far
    away and to enable arrangements to be made for appropri-
    ate intervention to prevent blindness, which is common in
    developing countries. Other applications allow for moni-
    toring of blood sugar of diabetics, hypertension, exercise,
    dietary management, and other aspects of health. In the
    same month, a camera, computer, and auditory device
    allowing blind people to “see and read” was demonstrated.
    The costs of such devices are initially high but will fall with
    advances in computing and other technical developments.

    In both developing and industrialized countries major
    causes of death include cardiovascular diseases (coronary
    heart disease and stroke), along with respiratory diseases,
    cancer and injuries, all amenable to preventive and cura-
    tive medical care. The key preventive measures for these
    are: healthful diet, reduced obesity, smoking cessation,
    exercise and physical fitness, hypertension management,
    aspirin, immunizations and other low-cost and highly effec-
    tive medications such as statins. These are all low-cost self-
    care measures that can be promoted by local, state, and
    national governments, private advocacy organizations, and

    775

    individuals in their families and communities. The princi-
    ples of low technology, cost-effectiveness, and sound health
    policy converge in addressing these fundamental issues.

    Priority Interventions in Low- and Medium-
    Income Countries

    Disease control priorities for low- and medium-income coun-
    tries are an important challenge for public health. Selection has
    often been based on individual initiatives due to strong advo-
    cacy in international organizations by donor countries, orga-
    nizations, or individuals. In 1993, two landmark documents
    attempted to apply a logical system to such considerations:
    one was the World Bank’s now classic World Development
    Report: Investing in Health and the other was Disease Control
    Priorities in Developing Countries. The World Development
    Report defined cost-effective clinical and public health cluster
    programs essential to improving health outcomes for low- and
    middle-income developing countries. The programs focus on
    those diseases that contribute heavily to the burden of disease
    and are amenable to relatively inexpensive interventions. The
    report defined interventions most able to reduce the burden
    of disease in low- and middle-income countries using clinical
    and public health interventions, as summarized in Table 15.2.

    The 1993 World Development Report provided policy
    makers and public health practitioners with a concept
    and tools for assessing cost-effectiveness of available
    interventions for the major health problems in the devel-
    oping world. It also provided useful measuring tools in
    the form of disability-adjusted life years (DALYs) to
    calculate the burden of disease and the cost-effective-
    ness of interventions to address them. This World Bank
    report addressed clinical interventions that would reduce
    DALYs lost by 24 percent in low-income countries and
    8 percent in middle-income countries, including treat-
    ment of TB, with directly observed therapy, short course
    (DOTS); integrated management of the sick child; pre-
    natal and delivery care; family planning; treatment of
    STIs; and limited care for pain, infections, and trauma
    as resources permit. It also addressed public health inter-
    ventions, which would reduce DALYs lost by 8.2 percent
    in low-income countries and 4 percent in middle-income
    countries, expanded immunization with vitamin A sup-
    plements; tobacco and alcohol control; AIDS prevention;
    and school health including deworming. Together, the
    total reductions would be 32 percent for low-income and
    12 percent for middle-income countries (Table 15.2).

    These estimates have been refined by numerous stud-
    ies conducted over the subsequent two decades. The sec-
    ond edition of the Disease Control Priorities in Developing
    Countries (2006) incorporates important changes in the
    technologies available. The concept of viewing priorities
    with an economic epidemiology model is still applicable,
    and has increased in importance (Box 15.1).

    776

    As the MDGs are reaching their endpoint in 2015,
    follow-up global health targets will need to recognize the
    vital importance of non-communicable diseases (NCDs)
    in developing countries. The global consensus on MDGs,
    set out by the United Nations (UN) in 2001, indicates
    progress in the epidemiological understanding of realities

    in low-income countries and the need for consensus over
    common targets. Since then, attention has been directed
    towards the epidemiological shift to NCDs, which are the
    most common causes of death in low- and medium-income
    countries. Thus there is a double burden of infectious, nutri-
    tion, maternal, and child priorities, alongside the NCDs.
    The increasing adoption of vaccines such as Haemophilus
    influenzae type b (Hib) and rotavirus alongside the standard

    l Average life expectancy in low- and middle-income
    countries increased dramatically since the 1960s, while
    cross-country health inequalities decreased.

    l Improved health has contributed significantly to eco-
    nomic welfare since the 1960s.

    l Five critical challenges face developing countries (and
    the world) at the beginning of the twenty-first century:

    – Micronutrient malnutrition for mothers and infants
    – NCDs
    – Possible pandemics.

    l Cost-effective interventions include:
    – Interventions to reduce neonatal mortality (50 per-

    cent of total child deaths)
    – Treatment of HIV-positive mothers, treatment of sex-

    ually transmitted infections
    – Controlling tobacco use, particularly through

    taxation
    – Lifelong medical management of risk factors in indi-

    viduals at high risk for heart attacks or strokes, using
    aspirin and other drugs, would benefit tens of millions
    of individuals.

    l Reform of health services and systems is needed,
    including:
    – Provider incentives
    – Provider focus on selected intervention to gain

    experience
    – Strengthening surgical capacity at district hospitals
    – Targeting limited resources to diseases affecting the

    poor, e.g., TB in low-income countries
    – In middle-income countries, public finance (or pub-

    licly mandated finance) of a substantial package of
    clinical care for all.

    l Generation and diffusion of new knowledge and prod-
    ucts underpinned the enormous improvements in health
    in the twentieth century and need to be applied for the
    control of NCDs, HIV, TB, and neglected populations.

    Chapter 15 Health Technology, Quality, Law, and Ethics

    diphtheria–pertussis–tetanus (DPT), poliomyelitis (polio),
    and measles–mumps–rubella (MMR) vaccines provides
    new possibilities to control the major infectious disease
    killers of children. New technologies such as the advent of
    antiretroviral treatment for HIV have led to startlingly suc-
    cessful improvements in the quality of life and longevity of
    HIV/AIDS patients, and the prevention of onward transmis-
    sion of HIV from mothers to babies and sexual partners.
    The WHO and many other global health stakeholders con-
    tinue this work and produce analyses to contribute to policy
    making based on economic epidemiological evidence. This
    work affects policy, slowly but importantly.

    In 2003, the Bellagio Study Group on Child Survival
    estimated that the lives of 6 million children could be saved
    each year if 23 proven interventions were universally avail-
    able in the 42 countries in which 90 percent of child deaths
    occurred in 2000. The MDGs set out in 2001 provided tar-
    gets for economic, educational, and environmental improve-
    ments, with three specifically focused on health: reducing
    child mortality; reducing maternal mortality; and control of
    HIV, TB, and other diseases. While important progress is
    being made, some of these targets will not be achieved by
    2015. The global public health infrastructure will need to be
    expanded in content and strengthened in order to implement
    lessons learned in childhood routine immunization, safe
    maternity care, and nutritional security (see Chapter 16).

    In medium- and low-income countries the difficulties are
    much more severe because of limited resources for health and
    the weak infrastructure of facilities and human resources in
    many countries. The key issues relate to NCDs, as in developed
    countries, so the interventions most needed address cardiovas-
    cular diseases, cancer, and injury, as well as diarrheal diseases,
    malnutrition, vaccine-preventable diseases, HIV, TB, malaria,
    and neglected tropical diseases. Efforts should be focused on
    low-cost interventions such as smoking reduction, vitamin and
    mineral fortification of foods, HIV, TB, and malaria control,
    along with maternal and child health protection.

    Priority Selection in High-Income Countries

    As discussed in Chapters 5 and 13, high- and middle-income
    countries also face complex health challenges, including
    aging populations, health costs, rapid development of new
    drugs and technologies, high rates of NCDs, and the rising
    prevalence of obesity and diabetes. Selection of priorities
    for health care expenditure from public and private sources
    has become a major focus of managing health systems.

    In the industrialized countries, technological advances in
    the medical and public health fields have been major contribu-
    tors to increasing longevity but also rising health costs. This
    situation has led to pressures for greater selectivity in adopting
    costly innovations without adequate assessment of benefits
    and costs. Many countries have adopted more cautious poli-
    cies with regard to financing high levels of expansion of new

    777

    technology in the field of medical equipment, clinical proce-
    dures, or medications. Organized assessment of technology is
    now an essential feature of health management at the interna-
    tional, national, and local levels of service delivery. The major
    responsibility for technology assessment is at the national
    level, even with decentralization of service management.

    With available resources being limited, health systems
    must choose interventions to be selected and how health
    systems are to be organized for efficiency and effectiveness
    while meeting public expectations. The US Patient Protec-
    tion and Affordable Care Act (PPACA, more generally called
    ACA or “Obamacare”) is undertaking reform measures to
    promote efficiency and prevention to reduce per capita health
    costs and to include more people in prepaid health care (see
    Chapters 10 and 13). These include preventive measures as
    recommended by Healthy People 2020 and implementation
    committees for selection of cost-effective measures to reduce
    morbidity and mortality to reduce health costs. The range
    of services to be promoted includes smoking cessation,
    increased physical activity, weight loss, healthy dietary prac-
    tices, cancer screening, and many others that have not been
    previously accessible to those living in poverty and with no
    or limited health insurance. There is an emphasis on vaccina-
    tion for children and adults.

    The WHO promotes the widespread use of basic radio-
    logical units (BRUs) to increase access to low-cost, effective,
    diagnostic X-rays, especially in rural areas in developing
    countries. BRUs are hardy, relatively inexpensive pieces of
    radiological examination equipment that can be used in harsh
    field conditions for simple diagnosis of fractures and respi-
    ratory infections. The WHO estimates that 80 percent of all
    diagnostic radiology can be performed adequately using sim-
    ple, safe, and low-cost equipment, supported by training of
    local people to operate and maintain the equipment. This is a
    consensus view of leading radiologists and clinicians helping
    the WHO to develop model equipment and training material.

    The WHO World Health Report of 2009 focused on
    health technology assessment, stating:

    “Technology continues to transform the medical care system and
    to improve length and quality of life – but at substantial cost. It
    is almost inconceivable to think about providing health care in
    today’s world without medical devices, machinery, tests, computers,
    prosthetics, or drugs. Medical technology can be defined as the
    application of science to develop solutions to health problems or
    issues such as the prevention or delay of onset of diseases or the
    promotion and monitoring of good health.”

    Appropriate technology in the health field is becoming
    increasingly complex, laden with economic, legal, and ethi-
    cal issues. Professional and public opinion demands make
    this a highly sensitive area of health policy, but responsible
    management of resources requires decision making that
    includes consideration of the effectiveness, costs, and alter-
    natives of any new technology (Box 15.2). Failure to adopt

    778

    new innovations can result in obsolescence, while excessive
    expenditures for hospitals and medical technology prevent
    a health system from developing more cost-effective pre-
    ventive approaches, such as improved ambulatory care, or
    supportive care for the chronically ill.

    HEALTH TECHNOLOGY ASSESSMENT

    Technology adoption can be a highly emotional and con-
    troversial issue, in advocacy of new cancer treatments or in
    criticism of managed care or national regulatory agencies,
    but spending limited national resources on some devices
    or medications of unproven value or inappropriately long
    hospital stays denies resources needed for other aspects of
    health care. A society must be able and willing to pay for
    medical innovation or improving quality of life by medical
    and public health interventions. Underfunding of a health
    system can deny these benefits just as misallocation of
    resources does, and this is a political issue even more than
    a professional one.

    Medical and health technology assessment is the pro-
    cess of determining the contribution of any form of care
    to the health of the individual and community. It is a sys-
    tematic analysis of the anticipated impact of a particular

    BOX 15.2 Health Technology Assessment

    Questions that form the basis of technology assessment for a
    medical innovation include the following:
    l Is it safe and cost-effective for the stated purpose?
    l Is it a new service, or does it replace a less efficient inter-

    vention which can be phased out of service?
    l What is the need it addresses?
    l Where is it in the order of priorities of development of

    the facility?
    l Does it duplicate a service already available in the

    community?
    l Does it make medical sense (i.e., does it help in diagnosis

    and treatment for the patient’s benefit)?
    l What are the alternatives?
    l What are the resources needed in terms of supplies, staffing,

    and upkeep?
    l Can the facility afford it?
    l What could otherwise be done with the resources it

    requires?

    The New Public Health

    technology in regard to its safety and efficacy as well as its
    social, political, economic, legal, and ethical consequences.
    The technology may be a machine, a vaccine, an opera-
    tion, or a form of organization and management of services.
    Analysis should include cost–benefit and cost-effectiveness
    studies (see Chapter 11) as well as clinical outcomes and
    other performance indicators.

    Pressures from medical professionals, manufacturers of
    new medical equipment, and the public for adoption of new
    methods can be intense and continuous. Care must be taken
    that the specialists involved in committees for assessment
    are not those who may directly or indirectly benefit from
    the exploitation of technology, and who therefore may have
    conflicts of interest. Assessment must be multidisciplinary,
    involving policy analysts, physicians, public health special-
    ists, economists, epidemiologists, sociologists, lawyers,
    and ethicists. The available information needs to include
    evidence from clinical trials, critical analysis of the litera-
    ture, and the economic effect of adopting the technology on
    allocation of resources.

    Medical technology varies in complexity and cost, not
    only to produce but in its utilization. Medical technology
    that is inexpensive to supply and administer is known as
    low technology or low-tech, while high technology or high-
    tech refers to costly and complex diagnostic and treatment
    devices or procedures.

    At the low-tech end of the technology scale, oral rehy-
    dration therapy (ORT) was developed in the 1960s for oral
    replacement of fluids and electrolytes lost in diarrheal dis-
    ease, particularly in children. It has been described as one
    of the greatest medical breakthroughs of the twentieth cen-
    tury. The introduction and wide-scale use of ORT for pre-
    vention of dehydration from diarrheal diseases throughout
    the world has saved hundreds of thousands of lives. Use
    of insecticide impregnated bed nets and reintroduction of
    DDT in household spraying along with vector control and
    improving diagnostic tools are low-tech but effective and
    key tools in malaria control.

    Advances in endoscopic surgical techniques since the
    1990s, and in robotic surgery since 2000, have greatly
    improved patient care by reducing trauma, discomfort, and
    length of hospital stay and endoscopy has become the surgi-
    cal approach of choice for many procedures. Since reports
    of the first 100 operations performed in France in 1990,
    endoscopy has spread rapidly to all parts of the world. It is
    now recognized by surgeons worldwide as a safer, less trau-
    matic and more effective alternative to traditional invasive
    surgery. Although the operating time is longer, patients are
    discharged from the hospital within several days and return
    to work shortly thereafter, compared to the long hospital
    stays after more invasive surgical procedures in the past.
    Following traditional abdominal surgery, a patient may
    acquire infections and require intensive care initially and a
    recovery period of many weeks.

    Chapter 15 Health Technology, Quality, Law, and Ethics

    Endoscopic surgery for cholecystectomy and esopha-
    geal, colorectal, hernia repair, renal, orthopedic, and other
    forms of surgery which previously were carried out with the
    patient remaining in hospital for many days are now done
    on a not-for-admission basis. Not-for-admission surgery has
    become standard practice in hospitals, extending the range
    of outpatient surgery and the comfort of patients who can
    return to their own homes to recuperate and return to regu-
    lar activities much sooner. Fewer complications arise and
    patient comfort and economic implications are important.
    As a result, fewer hospital beds are needed for postoperative
    care than previously thought necessary, while surgical and
    ambulatory care facilities may need expansion to accommo-
    date the growing elderly populations needing surgical inter-
    ventions but requiring shorter recovery. This innovation is
    now accepted as the standard of much of modern surgical
    care and shows that simple organizational changes can save
    money and improve patient safety and comfort.

    The bacterium Helicobacter pylori was first identified
    as the cause of peptic ulcers of the stomach and duodenum
    in 1982 (Robin Warren and Barry Marshall, Nobel Prize
    2005). This discovery led to effective diagnosis and rapid,
    inexpensive treatment of chronic peptic ulcer disease. This
    has resulted in elimination of a major component of surgi-
    cal procedures for chronic peptic ulcer diseases as well as a
    reduction in gastric cancer (see Chapter 4). Surgery for gas-
    trectomies, vagotomies, and other outdated forms of treat-
    ment are now virtually gone, contributing to a decreased
    need for hospital beds even for an aging population. This
    and many other innovations in medical care have led to a
    growth in the use of ambulatory care for many forms of
    surgical, medical, and mental health care, along with much
    shorter length of hospital stay than in previous times. All of
    these factors have led to greater emphasis on ambulatory,
    outpatient, and home care services.

    The dissonance between high-tech and low-tech proce-
    dures may lead to serious consequences in any health system.
    Choices require well-informed analysis of benefits, costs,
    alternatives, ethical considerations, and political consequences
    before limited health care resources are allocated between
    hospital-based high-tech medicine and low-tech primary care.

    High-tech procedures are usually applied in hospital
    settings in the context of other highly specialized care for
    seriously ill, often terminal, patients. Computed tomogra-
    phy (CT), invented in the 1960s, quickly proved to be an
    extremely valuable diagnostic tool. Advances in CT, mag-
    netic resonance imaging (MRI), and subsequent imaging
    techniques have proven to be cost-effective and lifesaving,
    replacing less efficient and more dangerous invasive proce-
    dures. The CT and MRI scans allow the clinician to reach a
    rapid diagnosis of many lesions before they can be detected
    by other invasive and dangerous diagnostic techniques, at
    stages where the lesions are subject to earlier and more
    effective interventions. Imaging technology is advancing

    779

    rapidly and promising inexpensive new systems for long-
    distance transmission of imaging to medical centers may
    provide enormous benefits to people living in rural or
    developing countries. Recent advances in low-intensity CT
    screening of long-term heavy smokers for lung cancer have
    recently been added to recommended and potentially effec-
    tive and cost-saving practice and may change the outlook
    for this disease in the coming decade (US Preventive Ser-
    vices Task Force, 2012 Flahault and Martin Moreno, 2013).

    Technology assessment also examines methods of pre-
    venting and managing medical conditions. Treatment proto-
    cols or clinical guidelines are based on decision analysis of
    accumulated weight of evidence. Published clinical studies
    are assessed in meta-analyses, using statistical methods to
    combine the results of independent studies, where the stud-
    ies selected meet predetermined criteria of quality. This pro-
    vides an overview from pooling of data, but also implies an
    evaluation of the studies and data used. Clinical guidelines
    are part of raising standards of care, but also contribute to
    cost containment. Many countries form professional study
    groups to carry out meta-analyses on important health pol-
    icy issues and new technologies.

    Technology Assessment in Hospitals

    There is considerable variance among countries, hospitals
    consume between 40 and 70 percent of total national health
    expenditures, with pressures for increased staffing and
    novel medical technology being a continual inflationary
    factor. Industrialized countries have all reduced their acute
    care hospital bed supplies and length of stay so that their
    expenditures for hospital care have fallen to between 30-40
    percent of total health expenditures. Shorter stays and older
    patients have resulted in a drift towards intensive care, espe-
    cially for internal medicine patients. Medical innovation is
    a continuing process with new diagnostic and treatment
    modalities reaching the market.

    Hospitals no longer live in splendid isolation in the
    medical economy. A national or state government needs
    regulatory procedures to rationalize distribution of medical
    technology. The “certificate of need” is a form of technology
    assessment that has been used in the USA since the 1960s
    to assess and regulate the development of hospital services
    to prevent oversupply and costly duplication of services. It
    attempts to establish and implement the use of rational crite-
    ria for diffusion of expensive new technology. Whether this
    has had a lasting impact on restraining the excesses of high-
    tech medicine is arguable. This regulatory approach was
    limited to the hospital setting and failed to stop the develop-
    ment of high-tech medical services such as ambulatory for-
    profit CT, imaging, and in vitro fertilization centers.

    Many countries have adopted national technology
    assessment systems to review topics as far-ranging as
    guidelines for acute cardiac interventions; liver, heart, and

    7

    80

    lung transplantation; minimal access surgery; and beam and
    isotope radiotherapy. Other technology assessment guide-
    lines include diagnostic ultrasound, sleep apnea, molecu-
    lar biology, prostate cancer, MRI, and new medications for
    inclusion in a national health system’s approved basket of
    services.

    Despite the limitations of this approach, where govern-
    ments do not directly operate health care services, gov-
    ernmental regulation is necessary to prevent inequities in
    services by excessive development in some geographic
    areas at the expense of others, or by overexpansion of the
    institutional sector of health care at the expense of primary
    care. Regulatory mechanisms are essential in health care
    planning to restrain excessive and inappropriate use of
    high-tech services, but need augmentation by fiscal incen-
    tives to promote other essential services.

    Hospitals everywhere face serious problems of hospital-
    acquired infections, which occur in about 5 percent of all
    hospitalizations. Healthcare-associated infections (HAIs),
    including multidrug-resistant bacterial infections, cause
    long lengths of stay, high costs, and most importantly, unex-
    pected deaths and serious disabilities. Prevention of hospital-
    acquired infection requires ongoing training, staffing, and
    organization. The Centers for Disease Control and Prevention
    (CDC) defines HAIs as “infections caused by a wide variety
    of common and unusual bacteria, fungi, and viruses during
    the course of receiving medical care”. Some of the preventive
    measures are simply promoting frequent hand washing by
    caregivers and visitors, and immunization of staff members
    against influenza and pneumonia, which can be problematic
    if there is staff resistance to influenza vaccination.

    Training and routine supervision of cleaning staff are
    also vital, as are strict infection control measures for isola-
    tion rooms, strict protocols for catheter care, surgical suite
    sterility, surgical site infections, central line associated
    bloodstream infections, ventilator-associated pneumonias,
    catheter-associated urinary tract infections, and Clostridium
    difficile-associated disease. Guidelines for their control in
    surgical dialysis, pediatric, outpatient, and other vulnerable
    departments are available from CDC. The benefits of pre-
    ventive procedures for this problem include cost estimates
    ranging from US$5.7–6.8 billion (20 percent of infections
    preventable) to US$25.0–31.5 billion, yet 70 percent of HAIs
    are preventable by well-known methods such as frequent and
    careful hand washing by medical and nursing staff, catheter
    and infusion care, and other similar measures (CDC, 2012).

    Technology Assessment in Prevention and
    Health Promotion

    Technology assessment of preventive care programs
    includes evaluation of the methodology itself, along with
    the costs and measurable benefits, as in reduced burden

    The New Public Health

    of disease. DOTS is the standard management of sputum-
    positive and sputum-negative TB, at low cost for DALYs
    saved. The coexistence of HIV and other complications
    has created multidrug-resistant tuberculosis (MDR-
    TB), which is difficult and costly to treat and cases
    constitute a source of continuing spread of the disease.
    A 2012 meta-analysis of cost-effectiveness of MDR-TB
    treatment in Estonia, Peru, the Philippines, and Russia
    shows it to be cost-effective and best carried out on an
    ambulatory basis (Fitzpatrick and Floyd, 2012).

    Wide use of available and effective vaccines such as
    Hemophilus influenza b (Hib), pneumococcal pneumo-
    nia, influenza and rotavirus reduce hospitalizations and
    mortality from respiratory and diarrhoeal diseases among
    children, the elderly and other age groups. Vaccine prices
    generally fall after their initial period of use as manu-
    facturing costs are lessened by improved methods or by
    bulk purchase contracts, as occurs in the public sector. For
    example, in 2012 MMR vaccine cost US$19.33 per dose if
    purchased through the CDC, but US$52.73 per dose if pur-
    chased in the private sector in 10 packs of single-dose units
    of the vaccine. A combined diphtheria, tetanus, acellular
    pertussis (DTaP) vaccine cost US$15.00 when purchased
    through CDC, while the same vaccine purchased with hep-
    atitis B and inactivated polio vaccine (IPV) cost US$52.10 per
    dose. But the combination saves repeated visits and loss
    of compliance for that reason. The new human papilloma-
    virus (HPV) cervical cancer vaccine cost US$130.27 per
    dose for the series of three doses per person, while the vac-
    cine against diarrhea-causing rotavirus, approved in 2006,
    cost US$106.57 per dose for the recommended three doses
    (CDC, 2012).

    The WHO recommends the inclusion of rotavirus vac-
    cination in a country’s immunization program, but the costs
    of the current generations of rotavirus vaccines are high in
    comparison to the budgets for vaccines for prevention of
    childhood illnesses in many developing countries. Many
    cost-effectiveness studies have shown this vaccine to be
    highly beneficial and it could help to reduce the very high
    global burden of disease of over 500,000 child deaths and 2
    million hospitalizations occurring annually (Tu et al., 2011).

    Vaccine programs must take into account transportation
    and administrative costs and expenses of ordering, storing,
    inventory control, cold chain, insurance, wastage, and spoil-
    age. Multiple vaccines in one dose are less costly and less
    inconvenient for all. Examples include DTaP plus polio and
    Hib, or MMR (see Chapters 4 and 6). There is a need for
    implementation of legal protection of manufacturers from
    excessive litigation judgments while protecting the interests
    of the public and individuals who may have reactions to
    vaccines.

    In 2012, the reappearance of pertussis and diphthe-
    ria raised concerns about immunization coverage and

    Chapter 15 Health Technology, Quality, Law, and Ethics

    efficacy. Public opinions on vaccination may not be as
    supportive as in previous years. Mothers who oppose per-
    tussis immunization for their children, such as occurred in
    the UK during the 1980’s, leave their children vulnerable
    to a serious and often deadly disease, which has recurred
    since 2010.

    The WHO estimates the cost of all immunization activi-
    ties in all 117 low- and middle-income countries for the
    period 2006–2015 to be US$75 billion, while low-income
    countries would need US$35 billion. The rate of adoption
    of currently available and new vaccines will be determined
    by governmental decisions in each country, although exter-
    nal aid – such as that of the Global Alliance for Vaccines
    and Immunization (GAVI), an international public–private
    consortium to promote vaccination – is a valuable resource.
    The United Nations Children’s Fund (UNICEF) is con-
    cerned about supply problems as well as costs, but the key
    issue relates to political decisions, funding, and capacities
    of national immunization systems.

    Despite an excellent vaccine having been available since
    the 1960s, measles epidemics continue to occur in the indus-
    trialized countries. In the 1900s global deaths from measles
    were in the order of 1 million people per annum. Two major
    epidemics of measles occurred in Canada in the early 1990s,
    despite high rates of immunization coverage. Following this, a
    1993 Delphi conference of experts from 31 countries reached
    a consensus recommending a two-dose measles immuniza-
    tion policy. Measles eradication has been set as a goal by the
    WHO and 90 percent reduction in cases and fatalities has
    been achieved since the 1990s. However, measles elimination
    requires coverage of 95 percent of children and two doses of a
    measles-containing vaccine (preferably MMR).

    Measles reappeared as a widespread disease in Europe in
    2010–2013 with tens of thousands of cases, many hospital-
    izations, and some deaths. It spread to the Americas, brought
    by travelers, and resulted in modest sized outbreaks, includ-
    ing the UK in 2012–2013. Eradicating measles by 2020 is
    projected to cost an additional discounted US$7.8 billion and
    avert a discounted 346 million DALYs between 2010 and
    2050. As new vaccines enter the field, it is important to evalu-
    ate their effectiveness, costs, and the benefits to be derived.

    The cost of the hepatitis B vaccine initially was over
    US$100 for an immunization schedule of three doses but
    has come down dramatically to less than US$1 per dose
    in developing countries for bulk purchases. However, in
    the USA, the price of vaccination per dose is estimated at
    US$41 if given by a general practitioner, US$15 if adminis-
    tered through an existing childhood immunization program,
    and US$17 if given through the school medical system.
    This is a standard vaccine covered by public and private
    health insurance systems. The vaccine is a cost-effective
    method to prevent liver cancer and the long-term effects of
    chronic hepatitis.

    Screening and education for thalassemia in high-prev-
    alence areas have nearly eradicated the clinical disease but
    not its carrier status in Cyprus, southern Greece, and other
    countries. Newborn screening and case management for
    phenylketonuria, congenital hypothyroidism, Tay–Sachs
    disease, and many other genetic diseases have been shown
    to be far less expensive than post-facto treatment of severely
    developmentally delayed and dependent children born with
    these diseases (see Chapter 6).

    The success of Papanicolaou (Pap) smear screening in
    reducing cancer of the cervix mortality since the 1960s has
    been dramatic. The discovery of causation of cancer of the
    cervix by HPV strains led to development of an effective
    vaccine, which has been in use since 2006. Recent evidence
    shows that male circumcision can reduce transmission of
    HPV as well as HIV and other sexually transmitted dis-
    eases, and it is being adopted as an effective intervention
    in countries with high rates of both HIV and cancer of the
    cervix, such as in sub-Saharan Africa.

    The drastic reduction in cancer of the cervix provides
    a powerful demonstration of the effectiveness of public
    health screening and other measures to control this major
    malignant cause of death in women. Screening for cervi-
    cal cancer by Pap smears is recommended annually for
    high-risk groups, and every 2 or 3 years for other adult
    women (Box 15.3). Screening will remain vital for many
    years to come as the HPV vaccine comes into general
    use, and as its cost is reduced, but its protective effect for
    individual and herd immunity will not replace the need
    for ongoing screening for this very common cancer. HPV
    vaccine is also being recommended for all boys to pre-
    vent oral and anogenital cancers and HPV transmission
    to girls.

    Routine mammography screening for breast cancer
    every 1–2 years is recommended by the US National Can-
    cer Institute for women over the age of 40 and for younger
    women with high-risk factors (e.g., previous cancer, fam-
    ily history, genetic markers). Cost-effectiveness analysis is
    now an essential part of decision making in health policy
    and priorities. While there is controversy over the frequency
    of routine testing, mammography remains a mainstay in
    women’s health and contributes to early case finding and
    falling mortality rates from breast cancer. Figure 15.1 dem-
    onstrates differences in utilization of mammography among
    US women in the age group 50–64 years within the previ-
    ous 2 years, by insurance status. US women with private
    insurance (mostly through place of employment) had over
    70 percent compliance, those with public insurance (pri-
    marily Medicaid) averaged about 60 percent compliance,
    while those with health insurance had average compliance
    rates of about 45 percent during the period 1993–2010.
    The UK National Health Service (NHS) invites women
    between the ages of 50 and 70 for screening every 3 years;

    Cancer of the cervix is the second most common cancer among
    women worldwide, with about 500,000 new cases and 250,000
    deaths worldwide annually. Approximately 80 percent of cases
    occur in low-income countries, where cervical cancer is the
    second commonest cancer in women (WHO, 2012).

    In the USA, and other industrialized countries, the incidence
    and mortality of cancer of the cervix have been going down
    steadily since the introduction of Papanicolaou (Pap) smear
    testing. Cervical cancer incidence declined during the period
    1999–2008 by 2.3 percent per year and mortality declined by
    1.9 percent per year an estimated 12,170 cases of invasive cer-
    vical cancer diagnosed in the USA with 4220 deaths in 2012.

    Prevention of cancer of the cervix has until recently mainly
    focused on Pap smears to detect the disease while still in a pre-
    cancerous (cancer in situ) phase, and this procedure reduced
    rates dramatically over the latter part of the twentieth century. The
    newly developed and highly effective vaccines against key strains
    of human papillomavirus (HPV) is now being used in routine
    immunization of young girls and more recently boys as well. The
    high cost of the vaccine precludes its rapid diffusion to most parts
    of the world but its use is spreading and being included in immu-
    nization programs funded by donor agencies in sub Saharan
    Africa. The vaccine should, in principle, also be used by adult
    women, in addition to continuation of routine Pap smear testing.

    In the past decade, evidence of HPV as the cause of cancer
    of the cervix and the presence of HPV in uncircumcised men has
    brought circumcision back to professional and public debate.
    Reports from Africa of reduced risk of acquiring HIV among
    circumcised men have brought new attention to adult male cir-
    cumcision, which is now actively promoted many sub-Saharan
    African countries.

    The technological breakthroughs of the Pap smear in the
    1950s, HPV testing in the 1990s, and the HPV vaccine in the
    2000s should also include prevention by male circumcision.
    Visual inspection of the cervix and cryotherapy can treat pre-
    cancerous cervical lesions in areas of developing countries
    as part of community health worker programs.

    Colorectal cancer, the 7th leading cause of death in high
    income countries, is amenable to prevention by early screening
    using colonoscopy and fecal occult blood (FOB) testing. Screening
    is recommended for all persons over age 50 at 5 year intervals
    along with annual FOB testing. Where there is a family history of
    colorectal cancer or polyps, routine screening should begin ear-
    lier. Increasing use of screening and improved medical care are
    resulting in improving survival and declining mortality rates.

    Stomach cancer is 10th leading cause of death in upper
    middle income countries. Prevention relies on early treatment
    of chronic peptic ulcer disease caused by Helicobacter pylori
    infection. This is readily diagnosed by a simple breath test and
    completely cured by low cost antibiotics. Increased awarenss
    and access to these services would enhance long term trends of
    reducing mortality from stomach cancer.

    Liver cancer is 8th leading cause of death in upper middle
    income countries due to the global prevalence of hepatitis B
    and helaptitis C. Hepatitis B is now falling due to widespread
    vaccination in childhood. Hepatitis C is now the major cause
    of liver cancer affecting hundreds of millions of persons world-
    wide. There is still no vaccine currently available, but screen-
    ing and treatment is now used in the industrialized countries
    and will become more widely used as simpler, less costly treat-
    ments with less side effects are becoming available.

    Early detection of lung cancer with spiral low dose
    tomodensitometry for smokers is recently being recommended
    by many professional bodies.

    More basic cancer preventive measures such as smoking
    cessation, healthy diets, regular exercise, and moderate alco-
    hol use are discussed in chapter 5.

    with an average of 75 percent respond to the invitation, of
    whom 4 percent are referred for further testing (UK Can-
    cer Research, 2012) and as in most industrailized countries
    breast cancer mortality rates are falling impressively (see
    Chapter 5).

    Health promotion in reducing exposure to HIV and
    cigarette smoking has been shown to be very cost-effec-
    tive despite its low-tech or non-technological meth-
    odology, involving primarily group or mass education.
    Hypertension screening and case management is low-
    tech but highly effective in preventing strokes and blind-
    ness.

    Low-tech innovations have had an important impact
    in reducing death and injury. These include mandatory
    use of car seat belts (introduced since the 1970s and
    1980s in many countries), children’s car seats, air bags,
    and bicycle and motorcycle helmets. Iodization of salt,
    vitamin A supplementation, and food fortification pre-
    vent large numbers of clinical cases of severe retarda-
    tion, death, and blindness at low cost per child protected.

    Education for reducing risk factors for the cardiovascu-
    lar disorders is far less costly than the premature deaths
    and high medical costs of patients suffering stroke and
    congestive heart failure. Health education, condom and
    needle supply, and screening of blood donations are the
    most important effective community health measures
    against the spread of HIV. Table 15.3 shows a compari-
    son of high-tech and low-tech approaches, which often
    complement each other, to selected health problems.

    Technology assessments represent the current con-
    sensus derived from reviews of published studies and
    exchange of views of highly qualified clinicians, epide-
    miologists, and economists within a context of technol-
    ogy assessment. They may change over time as new data
    or innovations are reported, and this possibility should
    be kept in mind in such discussions. Technology assess-
    ment mobilizes information and critically analyzes many
    aspects of medical technology to build a wide community
    consensus to influence policy decisions. Public opinion,
    political leadership, and administrative practice, as well
    as the scientific merit of a case are all factors in develop-
    ing a consensus.

    Technology Assessment in National Health
    Systems

    Technology assessment requires an organization within
    the framework of national regulatory agencies. The FDA
    serves this purpose as a statutory body within the US Pub-
    lic Health Service. Sweden, Canada, Australia, the UK, the
    Netherlands, Spain, and other countries also have technol-
    ogy assessment advisory or regulatory agencies established
    by national governments to monitor and examine new tech-
    nologies as they appear. Sweden has a widely representa-
    tive national Swedish Council for Technology Assessment
    in Health Care which has an advisory role to the national
    health authorities.

    The processes used in traditional systems to regulate
    food and drugs for efficacy, safety, and cost are more
    recently being applied to new medical devices and proce-
    dures. The unrestricted proliferation of new procedures
    presents serious dilemmas for national agencies con-
    cerned with financing health care and controlling cost
    increases. Non-governmental health insurance shares
    this concern, as does industry, which bears much of the

    784

    cost of health insurance through negotiated, collective
    bargaining, “voluntary” health insurance in the USA.
    Most industrialized countries have national health ser-
    vices or national health insurance and are thus vitally
    interested in health costs and technology assessment.
    Many industrialized countries maintain technology
    assessment and cost-control activities. In the USA, the
    Agency for Healthcare Research and Quality (AHRQ)
    maintains oversight and studies related to clinical infor-
    mation, including evidence-based practice, outcomes and
    effectiveness, comparative clinical effectiveness, risks
    and benefits, and preventive services.

    In Canada, the Health Protection Branch of the Federal
    Department of Health reviews medical devices and drugs
    and, with consent of the provincial governments, approves
    new medical procedures. Concern by governments over the
    cost implications of new procedures led to this practice.
    Since 1988, a network of government and professional
    bodies has formed a non-profit agency for technology
    assessment (Canadian Agency for Drugs and Technologies
    in Health, CADTH). This supports the provincial adminis-
    tration of health insurance in resisting professional, com-
    mercial, or political pressures to add untested technology
    or procedures to the health system as covered benefits. A
    comparison of rates of procedure performance between
    provinces shows very high discrepancies, as high as two-
    fold, in procedures such as coronary artery bypass graft or
    prostatectomy. Control of acquisition of high-tech equip-
    ment by national or state authorities is essential to prevent
    expenditures on high-cost equipment without adequate
    assessment.

    The New Public Health

    DISSEMINATION OF TECHNOLOGY

    The rapid spread of high-tech medical equipment has played
    a substantial role in escalating health costs. A comparison of
    the number of MRI scanners per million population in mem-
    ber countries of the Organisation for Economic Co-operation
    and Development (OECD) (Table 15.4) showed Japan and the
    USA with the highest number at 43.1 in 2010 (23.2 in 2000–
    01) and 31.6 (15.4 in 2000) per million, respectively, while
    the median was 10.5. Canada ranked fourteenth among the 20
    OECD countries with 8.2 MRI scanners per million. Compar-
    ing CT scanners showed that Japan had the highest number
    at 97.3 while the median was 15.6. Canada was in eighteenth
    place among the 28 OECD countries reporting in 2010 with
    14.2 CTs per million population. However, it should be noted
    that countries with the most machines have lower productiv-
    ity per machine. The USA has far fewer examinations per
    machine than other countries (OECD, 2012).

    The use of endoscopic surgery has spread worldwide
    since the 1990s. Health professionals become almost
    instantly aware of new developments from the news media
    as well as professional diffusion of information at confer-
    ences, in exchange visits, in published articles, and most
    dramatically via the Internet. National policy to foster the
    introduction of appropriate new technology requires a
    careful program of regulatory and financial incentives and
    disincentives to encourage or discourage diffusion of new
    methods of prevention as well as of treatment and com-
    munity health care. Kidney transplantation has become a
    cost-effective and patient-friendly alternative to long-term
    dialysis both in hospital and at home. The key limitation is

    the shortage of donors. The same can be said for liver trans-
    plantation, which has also been shown to be cost-effective
    in terms of DALYs saved from chronic liver diseases such
    as cirrhosis and hepatitis B and C. Heart transplantation has
    spread among major centers in western countries.

    The black market in organs for transplantation has
    become an international scandal of exploitation of poor
    people in low-income countries, and is the subject of police
    investigation in many countries, but it is difficult to control.

    Bone marrow transplantation is now used widely and
    is effective in saving the lives of many people with malig-
    nant and non-malignant hematological disorders. Stem cell
    therapy, by introducing new adult and embryonic stem cells
    into damaged tissue to treat disease or injury, is becoming
    feasible for a wide variety of conditions including cancer,
    type 1 diabetes mellitus, Parkinson’s disease, Huntington’s
    disease, celiac disease, cardiac failure, muscle damage, and
    neurological disorders.

    Limitation of new techniques or procedures to selected
    medical centers allows the passage of time to fully assess
    the merits and deficiencies of new technology before gen-
    eral diffusion into the health care system. Such limitation,
    however, is fraught with the danger of depriving the popu-
    lation of benefits of new medical technology, and the pos-
    sibility of restraint of trade to the economic advantage of
    selected providers. Current advances in robotic-assisted sur-
    gery will expand during the coming decade for brain, bone,
    joint, prostate, and other surgery, and need to be assessed
    with regard to patient care benefits, costs, and the econom-
    ics of capitalization of such innovations. Stem cell therapy
    is already widespread for some malignant conditions, and
    with advances in genomics and molecular biological tech-
    nology it is very likely to become a major therapeutic inter-
    vention for many more conditions in the coming years. The
    effects of new technology on insurance and managed care
    systems are necessarily involved in decision making as to
    inclusion of new procedures in their service plans.

    Publication in the professional literature is an accepted
    method of establishing the scientific merit of a treatment or
    an intervention. Too rapid diffusion of a medical practice
    can lead to disillusionment and confusion as to the mer-
    its of a particular medical procedure, as happened during
    the 1960s and 1970s with anticoagulant therapy for acute
    myocardial infarction and gastric freezing for peptic ulcers.
    Reviews of the literature should be critical and should
    assess the scientific merits of published data, as well as the
    sources of funding. Well-controlled large-scale clinical tri-
    als are vital to establish the relative values of alternative
    therapeutic approaches, as are meta-analyses of multiple
    studies.

    Dissemination of information about new medical inno-
    vations in the popular media is almost immediate. Many
    major newspapers and television networks have well-
    informed medical reporters and commentators who have

    785

    access to electronic medical journals as quickly as do medi-
    cal specialists in each field. News magazines may carry spe-
    cial articles on new innovations, creating instant demand for
    them as benefits in a health program. This ready access to
    information has both benefits and dangers.

    In the USA, health insurers have led the way in develop-
    ing technology assessment and information synthesis, and
    in evaluating the costs and benefits of new procedures. The
    process is affected by public opinion, as well as by court
    decisions. A landmark decision against a health mainte-
    nance organization (HMO) in 1993 awarded US$29 million
    in damages to the family of a terminal breast cancer patient
    who died following refusal of the HMO to authorize a bone
    marrow transplant, which was at the time an experimental
    procedure. Denial of new technology may lead to increases
    in malpractice suits. In countries with limited financial
    resources, selection of technological innovations in health
    care that can benefit patient care or the public health
    requires a careful balance in order to use limited resources
    well, and to gain from the application of appropriate new
    health care technology.

    Payment systems by national or private insurance
    systems are crucial to introduce and control diffusion of
    technology. Block budgets for hospitals have been more
    effective in Canada than in the USA in restraining the pro-
    liferation of high-tech equipment. This has led to criticism
    of the limited access of Canadians to medical technology,
    such as CT, MRI, and advanced cancer therapies. In the
    USA, universal application of the diagnosis-related group
    (DRG) payment system for Medicare, Medicaid, and most
    private insurance had the effect of increasing ambulatory
    surgery very dramatically, from 16 percent of all surgery
    in 1980 to 80 percent in 2008 of all surgical procedures in
    community hospitals (i.e., non-federal short-stay hospitals
    or 85 percent of all hospitals in the country). Inpatient sur-
    gical procedure rates declined from 85 percent in 1980 to
    35 percent in 2008. Although the rate of visits to hospital-
    based surgery centers remained largely unchanged in the
    USA from 1996 to 2006, the rate of visits to private ambula-
    tory surgery centers increased by about 300 percent.

    HMOs and managed care organizations are paid on a
    per capita basis and have a strong incentive for cost contain-
    ment. They have developed procedures and medical guide-
    lines for investigation and intervention that seek to reduce
    unnecessary procedures. At the same time, HMOs are very
    active in promoting preventive care and non-hospital care
    insofar as this is compatible with good patient care.

    Coronary bypass procedures decreased in frequency in
    the USA between 2001–02 and 2007–08. In the USA, such
    procedures are less frequently carried out in women and
    African Americans, because of lesser access to health insur-
    ance for African Americans and possibly because of biases
    in terms of case assessment criteria in women. Cardiac
    invasive procedures increased dramatically since the 1980s

    786

    in most industrialized countries, but with wide variation in
    their use. The benefits of aggressive invasive management
    of cardiovascular diseases remain controversial, but many
    such procedures have proven beneficial in reducing mortal-
    ity rates and improving quality of life.

    Critical analysis of the need for surgery has resulted in
    lower tonsillectomy and radical mastectomy rates along
    with the increased use of outpatient procedures. Tonsillec-
    tomy, a routine procedure until the 1960s, is now performed
    infrequently since it was found to be of little medical value.
    Cataract surgery is now largely done on an ambulatory
    basis. The technology of home care has come to play an
    important role in early discharge of patients from the hospi-
    tal, as has the wide use of cancer chemotherapy and radia-
    tion therapy on an outpatient basis.

    DIFFUSION OF TECHNOLOGY

    Innovations in health care through scientific and technologi-
    cal advances are continuing, with exciting breakthroughs
    being made in effective new treatments and public health
    interventions, and this requires health authorities, practitio-
    ners, and the public to maintain constant awareness of the
    current state of the art. Diffusion of new technology or adap-
    tations from basic science advances may begin slowly, and
    then reach a “tipping point”, at which time a dramatic change
    of trend occurs and it becomes the new standard or fashion.

    Those with economic interests in the product try to
    advertise and promote sales, while practitioners are ready
    to try new methods to help their patients, but those who
    must pay for services may ask for evidence of effectiveness,
    safety, added value over present and known methods, and
    benefit to the length or quality of life of the individual. This
    can become a highly charged debate when those responsible
    for adopting new measures in national health plans must
    weigh one proposed addition against another, each with its
    ardent professional, community, or business promoters. The
    new HPV vaccine approved by the FDA in 2006 for preven-
    tion of cancer of the cervix is an example.

    The HPV vaccine is recommended for preteen girls at the
    age of 11–12 years and also for females aged 13–26 to off-
    set future sexual exposure to HPV-infected males and since
    2012 recommended routinely for teenage boys as well. The
    two competing main manufacturers of HPV vaccine are nat-
    urally interested in increasing their market and market share,
    and willing to reduce prices. The cost has been lowered
    substantially for use in developing countries if purchased in
    bulk, but costs are still prohibitive unless funded by interna-
    tional donors. Competing low-cost manufacture in India has
    encouraged the two main manufacturers to lower prices to
    seek broader markets. In 2011, one manufacturer lowered its
    price dramatically to US$5 per dose, a 67 percent reduction
    in the current lowest public price. This has allowed GAVI to
    adopt an HPV strategy for developing countries, where 88

    The New Public Health

    percent of cervical cancer deaths occur, with 275,000 deaths
    of relatively young women each year (GAVI, 2011, 2012).

    Pioneering projects promoting visual examination of the
    cervix and local cauterization of abrasions by trained nurses
    and community health workers are meant to increase access
    to care in traditional villages remote from medical centers.
    The duration of immunity and whether booster doses will
    be required are still not known. Policy makers need to con-
    sider whether the same money would have greater benefit
    if used to provide pneumococcal pneumonia and rotavirus
    vaccine for children in developing countries, which would
    quickly save hundreds of thousands of lives. It is likely that
    the wonderful new public health technology that is the HPV
    vaccine will be absorbed quickly into public health prac-
    tice at least in the industrialized countries, and is now being
    introduced by international donor agencies in sub-Saharan
    Africa.

    QUALITY ASSURANCE

    Quality assurance is an integral part of public health func-
    tion and involves ensuring the quality of both health prac-
    titioners and facilities. It is an approach that measures and
    evaluates the proficiency or quality of services rendered.
    Hospital accreditation is a long-standing method of qual-
    ity assurance, providing many generations of health provid-
    ers in North America with first hand experience of quality
    assurance in community hospitals and long-term care facili-
    ties, as well as ambulatory and mental health services.
    Hospital accreditation has contributed to improvement in
    standards of facilities and patient care throughout Canada
    and the USA and has provided a working model for replica-
    tion or adaptation internationally.

    Adverse Events and Negligence

    Iatrogenic diseases are adverse events that occur as a result
    of medical management and result in measurable disability.
    Negligent adverse events are those events caused by a failure
    to meet standards of care reasonably expected of the aver-
    age physician or other provider of care. Hospital-acquired
    infections, anesthesia mishaps, falls, and drug errors are the
    most common iatrogenic events.

    Iatrogenic disease is a major cause of morbidity, pro-
    longation of hospitalization, and even death. Hospital-
    acquired (nosocomial) infections are estimated to occur
    in 7–10 percent of hospital cases in Britain and the USA.
    Primarily these are caused by urinary, respiratory tract, and
    wound infections. It is becoming more common that infec-
    tions involving organisms previously responsive to antibi-
    otics are now resistant to many antibiotics and difficult to
    treat. Infection control in hospitals is therefore an essential
    part of hospital organization. Because hospitals are increas-
    ingly being paid by DRGs, any secondary event prolonging

    Chapter 15 Health Technology, Quality, Law, and Ethics

    hospital stays may have adverse financial effects on the hos-
    pital. In the USA, recent decreases in Medicare reimburse-
    ments for nosocomial infections reflect this trend to provide
    financial incentives to improve hospital infection control.
    There is, therefore, a strong financial as well as professional
    interest in reducing hospital-acquired infections.

    A classic study of 32,000 hospitalizations in New York
    State carried out by a Harvard University team showed
    that 3.7 percent of hospitalized patients suffered adverse
    events or injuries caused by medical mismanagement which
    resulted in measurable disability. Of these, 28 percent were
    due to negligence, so that 1.03 percent of all hospitalizations
    involved medical negligence leading to measurable injury.
    Of the total of some 100,000 adverse events in the study
    group, 57 percent recovered within a month and 7 percent
    had severe injury. Some 14 percent or 14,000 people with
    adverse events died as a result; 51 percent of these deaths
    were due to negligence. A 1999 report of the US National
    Institute of Medicine estimated that between 44,000 and
    98,000 people die annually in the USA from medical errors
    occurring in hospitals, but these data are considered to be
    overestimated in some studies. Adverse drug events (ADEs)
    result in 700,000 emergency department visits and 120,000
    hospitalizations annually, with US$3.5 billion spent on
    extra medical costs. CDC estimates that at least 40 percent
    of the costs of ambulatory (non-hospital setting) ADEs are
    preventable.

    A 2008 report by the Office of Inspector General of the
    US DHHS reported that 13.5 percent of Medicare benefi-
    ciaries experienced adverse events and that for 1.5 percent
    of beneficiaries, these adverse events contributed to their
    deaths. An additional 13.5 percent of beneficiaries in the
    sample experienced temporary harm as a result of their
    medical care, bringing the total percentage of beneficiaries
    experiencing instances of care-related harm to 27 percent.
    Nearly half (44 percent) of these adverse or temporary harm
    events were preventable.

    Hospital-acquired infections cause 99,000 patients
    deaths in the USA every year (AHRQ, 2009). Higher rates
    are seen among the elderly and the poor. Rates are lower in
    teaching hospitals than in community hospitals. About 20
    percent of the events were related to drug reactions or dos-
    age errors. Less than 3 percent of those injured brought civil
    litigation for the negligence. The search for “bad apples” –
    that is, unethical, criminal, or incompetent health providers –
    is necessary, but not sufficient to stem the problems created
    by the health system itself. Prevention requires organized
    activity. Investigation of adverse events helps to identify
    methods of prevention and to protect the patient’s rights.
    A program of measures to reduce hospital infection must be
    based on epidemiological analysis of recorded events in the
    search for common causes and preventable factors.

    Organized surveillance and control requires a ratio of
    one infection control practitioner per 250 acute care beds,

    787

    a trained hospital epidemiologist, and routine reporting of
    wound infections to practicing surgeons (CDC, Hospital
    Infection Program). Computer-aided medication dispens-
    ing, as well as automated and other safety systems are
    critical elements in minimizing morbidity and mortality
    resulting from preventable human errors. In response to
    the high frequency and cost of medical litigation, many
    states in the USA have enacted legislation to restrict court
    awards for medical negligence. Proposals for alternatives
    to the tort system of medical malpractice compensation
    include arbitration and mediation, an administrative sys-
    tem similar to that used for workers’ compensation, and
    a no-fault system of compensation, such as exists in New
    Zealand, Sweden, and Finland. In a no-fault system the
    complainant need not prove negligence on the part of the
    provider, but only that he or she suffered an adverse event
    which is compensable at standard rates depending on the
    degree of disability. In the USA, federal legislation pro-
    vides compensation for vaccine injuries, and three states
    have enacted restricted no-fault systems for birth-related
    neurological injuries.

    In addition, there is greater emphasis on the adoption of
    failsafe mechanisms, such as introducing warning systems
    in anesthesia machines to alert the anesthetist if oxygen
    flow in the patient’s tubing falls below a safe point. This
    system was tested in Boston hospitals and found to reduce
    adverse anesthetic events to zero cases over a 3-year period.
    Vitamin K injection was made mandatory for all newborns
    in New York State, as was already the case in some other
    states, when a study showed deaths from hemorrhagic
    disease of the newborn in cases where vitamin K was not
    administered.

    Inappropriate medical practice patterns are an equal, or
    even larger problem for health systems. Comparisons of
    surgical rates within the USA for coronary bypass proce-
    dures, hysterectomies, and caesarean sections show wide
    variation between different areas of the country. The costs
    of excess surgery not only are economically wasteful but
    also involve risks for the patient from the surgery itself
    or anesthesia mishaps, infection, pain, and discomfort,
    with legal and ethical questions of unwarranted interven-
    tions not for the benefit of the patient. Health systems are
    increasingly required to evaluate and control excess surgi-
    cal, investigative, or other medical procedures, not only for
    financial reasons but also for protection against litigation
    and infringement of patients’ rights.

    Licensure and Certification

    The requirements that society establishes for allowing an
    individual to practice medicine, and any health profession,
    are vital to maintaining and improving the quality of care
    (see Chapter 14). These standards require defining the train-
    ing and experience needed by the individual, examination

    788

    procedures, and recognition for continued education and
    maintenance of competence. This requires a statutory base
    and national bodies operating under a national authority, sep-
    arate from the agency operating the health system services.
    Separation of licensing from operation of the health service
    is essential in maintaining high professional standards.

    The licensing authority is accountable to the state and
    the public. In some cases, this function is delegated to self-
    regulating professional bodies. In Canada, the licensing of
    the medical profession and specialty recognition are carried
    out by the medical profession with self-regulation. In the
    UK, medical licensing is by a state-appointed board and in
    the USA by state boards.

    Medical schools, postgraduate training programs,
    and fellowships are all subject to periodic comprehensive
    assessments. Institutions that fail to meet the standard may
    have funding or licensure suspended until they have per-
    formed adequate remediation.

    Health Facility Accreditation

    Hospital accreditation in North America is by a voluntary
    grouping of professional associations, including the Cana-
    dian and American Colleges of Physicians and Surgeons,
    the hospital associations, and the Colleges of Nurses. The
    Joint Commission, originally operating in both Canada and
    the USA, carries out regular inspections of hospitals. In Can-
    ada, other organizations including the federal Department of
    Health, provincial ministries of health, the Canadian Diabetes
    Association, the Public Health Association, and the Standards
    Council of Canada participate in the Joint Commission as
    observers. Initially focusing on acute care hospitals, accredi-
    tation has been gradually extended to cover special hospi-
    tals, long-term facilities, home care programs, public health
    departments, and ambulatory care services.

    Health facility accreditation is a systematic, multidisci-
    plinary inspection of the physical and organizational struc-
    ture of the facility or program and the functioning of its
    component parts. Factors measured include staff qualifica-
    tions, facilities, organization, record keeping, and continu-
    ing education of staff.

    The process of accreditation requires a request for
    accreditation from the board of governors of the hospital
    or health facility, implying acceptance of the standards
    of the commission. The accreditation process includes a
    self-assessment, an on-site survey, and follow-up action
    for correction of deficits and improvements. The com-
    mission is invited to conduct a survey, and resurvey as it
    sees fit. The hospital pays a fee and commits itself to pro-
    vide all data requested and to cooperate with the site visit.
    The commission issues a confidential report, giving the
    accreditation rating and interim statement of deficiencies,
    and requests progress reports in correcting deficiencies. It
    is also empowered to carry out follow-up inspections and

    The New Public Health

    resurveys. Box 15.4 lists the areas of a large community
    or teaching hospital, regional health authorities, hospitals,
    and community-based programs and services, from both
    private and public sectors, not only in Canada but around
    the world.

    The assessment survey examines the goals and objec-
    tives of the organization and its administration, the direc-
    tion and staffing of the facility, policies, and procedures.
    Review includes medical staff organization, credentials and
    review procedures, clinical privileges, selection of depart-
    ment chairpersons and their responsibilities, standing com-
    mittees, schedule of meetings, bylaws, and the role of the
    governing board of the hospital. The presence and nature of
    quality assurance organization, records review procedures,
    and continuing educations are assessed. The quality of
    clinical records is assessed by examination of charts for the
    completeness of histories and documentation of the course
    of the hospital stay including laboratory reports.

    Each section of the program being accredited is assessed
    in the following categories:

    l statement of purposes, goals, and objectives
    l organization and administration
    l human and physical resources
    l orientation, staff development, and continuing education
    l patient care
    l quality assurance.

    These categories are also used in the programs covered
    by the contracts between Accreditation Canada, formerly
    the Canadian Council on Health Services Accreditation
    (CCHSA), and other health and social service agencies.

    Hospital accreditation was established in the UK and
    Australia in the 1980s and is attracting interest in other
    countries seeking ways to maintain and promote standards.
    The procedure for accreditation of hospitals is still volun-
    tary in Canada, but in effect has become universal for hos-
    pitals of medium and large size (over 75 beds) and common
    for smaller hospitals. It is seen as advantageous for the gov-
    erning board and the community and also for the medical
    staff in terms of medicolegal protection. In the USA, hospi-
    tal accreditation has become virtually universal since pay-
    ment for federally funded health insurance (Medicare and
    Medicaid) beneficiaries is not allowed for non-accredited
    hospitals, and many private insurers make this requirement
    as well. In some states, accreditation is mandatory for all
    hospitals.

    Since the 1990s, CCHSA’s accreditation program has
    expanded to cover a diversity of health care and service
    areas, through contract arrangements with independent non-
    hospital facilities such as highly specialized programs as well
    as community health and social service organizations. In 2006,
    CCHSA introduced standards for child welfare, hospice, pal-
    liative and end-of-life care facilities, prison facilities, biomedi-
    cal laboratories, and supplementary criteria for telehealth. In

    BOX 15.4 Accreditation Canada Standards

    2008 CCHSA officially became Accreditation Canada, pro-
    viding services to other countries. The ever-changing health
    and social environment now accommodates specialized needs
    in a diversity of service areas as an adjunct to the hospital
    accreditation process. Examples are shown in Box 15.5.

    Licensing and regulation of health facilities are a gov-
    ernment responsibility, but an independent accreditation
    authority has advantages. The national authority may fail to
    monitor its own facilities with the diligence or objectivity
    needed, and there may be a conflict of interest. Where there
    is a national system of organization, distinct departmen-
    talization of the operating and certification functions may
    provide a greater measure of objectivity. Assistance from
    countries experienced in voluntary accreditation can help to
    establish accreditation mechanisms and provide technical
    and professional support to countries wishing to establish
    such programs.

    In the current period of transition from central to decen-
    tralized management of health services in many countries,
    health facilities are being transferred from government

    operation to independent operation as not-for-profit or
    even for-profit facilities. Present methods of regulation by
    national or state levels of government will require review
    as decentralization and privatization take place. Regulation
    by governmental authorities and non-governmental pro-
    fessional bodies is mutually complementary in promoting
    accountability, standards, and quality of services.

    Peer Review

    A large part of the work of clinical and departmental man-
    agers in hospitals or other care settings relates to qual-
    ity assurance. A major method of improving quality in a
    health program is through peer review by which the staff
    organizes systematic review of cases and records, using
    statistics on performance indicators. In hospitals, this
    includes review of deaths, maternal mortality and infant
    mortality cases, surgical rates, complications following
    surgery, and infection rates. Medical records and com-
    puter information systems permit users to review records

    BOX 15.5 Accreditation Canada International
    Accreditation Program

    The Canadian health services accreditation program began
    in 1917 in conjunction with the American College of
    Surgeons (ACS) with a hospital standardization program. The
    first Minimum Standard for Hospitals developed require-
    ments of just one page. In 1918, on-site inspections of hos-
    pitals began, with 89 of 692 hospitals surveyed meeting the
    requirements of the Minimum Standard. In 1926, the first
    Standards Manual was issued.

    In 1951, the American College of Physicians, the
    American Hospital Association, the American Medical
    Association, and the Canadian Medical Association joined
    with the ACS to create the Joint Commission on Accreditation
    of Hospitals (JCAH). It is an independent, not-for-profit orga-
    nization whose purpose is to provide voluntary accredita-
    tion. In 1953, the Canadian Hospital Association (now the
    Canadian Healthcare Association), the Canadian Medical
    Association, the Royal College of Physicians and Surgeons,
    and l’Association des Médecins de Langue Française du
    Canada established the Canadian Commission on Hospital
    Accreditation. The Commission’s purpose was to create a
    Canadian program for hospital accreditation, and in 1958
    the Canadian Council on Hospital Accreditation (CCHSA)
    was incorporated.

    In 2008 CCHSA became Accreditation Canada
    International. The accreditation program is used by all
    types of health facilities, from large and complex hos-
    pitals, to health systems, community health organiza-
    tions, and residences providing long-term care. Its scope
    includes a wide range of programs, including standards
    on child welfare, hospice palliative and end-of-life care,
    biomedical laboratory services, blood banks, and supple-
    mentary criteria for Telehealth. The accreditation program
    covers a diversity of health care and service areas, service
    programs for brain injury, ambulatory care, assisted repro-
    ductive technology – clinical and laboratory services,
    Canadian Forces health services, cancer agencies, child
    welfare organizations, First Nations and Inuit addictions
    and community health services, the Federal Department
    of Veterans’ Affairs, substance abuse and problem gam-
    bling treatment services.

    The accreditation service is on a contract basis with
    specialized health programs, other federal government
    departments, for-profit health facilities, and community
    organizations across the provinces.

    Accreditation Canada International works with other
    countries to develop national accreditation programs for
    their countries, and launched its first international program
    for acute care, primary care, ambulatory care, and clinical
    laboratories in 2010.

    by diagnosis. These records can be utilized to assess other
    events in hospitals, such as time from admission to sur-
    gery, lengths of stay by diagnosis, response to abnormal
    laboratory findings, and many other indicators of the pro-
    cess of care. Obstetric departments can review the fre-
    quency of and criteria for caesarean section deliveries.
    Surgical departments review their appendectomy rates to
    separate pathological findings from normal appendices.
    Organized peer review has also been called medical audit
    and essentially describes methods of self-policing and
    education to learn from mistakes and experience and to
    improve the quality of care.

    In 1972, an amendment to the US Social Security Act
    required hospitals and long-term care facilities to moni-
    tor the quality of care given to Medicare and Medicaid
    patients through professional standards review organiza-
    tions (PSROs). These were medical audit committees with
    specified tasks to conduct utilization review, medical care
    evaluation, and profile analysis of physician or institutional
    performance compared to accepted standards of the medical
    community. In 1982, peer review organizations (PROs) were
    created by federal statutes to replace PSROs. The PROs are
    non-profit corporations, staffed by physicians and nurses,
    to review medical necessity, quality, and appropriate level
    of care under the Medicare and Medicaid programs. The
    Centers for Medicaid and Medicare Services have an Office
    of Clinical Standards to conduct surveys, provide certifica-
    tion, and develop best practices guidelines, in a health care
    quality improvement program (HCQIP).

    Hospitals have departmental clinical meetings, adverse
    incident or outcome committees, mortality rounds, and
    clinical pathology conferences to help staff to evaluate and
    learn from difficult cases. The presence of functioning peer
    review mechanisms indicates that quality is of concern to
    the professional and administrative network, raising the
    consumer’s confidence in the system.

    Maternal mortality committees have been widely used
    to assess preventable factors in deaths related to maternity
    and to point out areas of needed improvement in services.
    Identification of high-risk pregnancies emerged from this
    process and has become an important part of prenatal care.
    Infant mortality reviews by professional groups can simi-
    larly demonstrate areas of needed improvement in services.
    Death rounds are held to review cases of death following
    surgery or soon after admission, or “incidents”, such as
    inappropriate medication given in error.

    The successive waves of peer review initiatives in
    the USA represent attempts by the federal government
    to establish mandatory quality of care review by profes-
    sional peers for facilities providing care to Medicare and
    Medicaid patients. The concept of requiring standards of
    care review has probably contributed to a greater aware-
    ness of the accountability of hospital-based practice. Fre-
    quent litigation may have contributed more to the sense that

    Chapter 15 Health Technology, Quality, Law, and Ethics

    the physician is accountable for services and outcomes of
    care. PROs are a form of quality regulation that represent a
    commitment by funding agencies to accountability in care
    systems and to identification of organizational and admin-
    istrative weaknesses in health care generally and not only
    in hospitals. The generation of US physicians and health
    systems managers trained since the 1970s accepts peer
    review as an integral part of health services. Other coun-
    tries use this kind of mechanism to maintain and promote
    quality of care.

    Tracer Conditions

    Tracer conditions are common medical conditions (or pro-
    cedures) for which diagnostic criteria are well established
    and clear, there are effective preventions or treatments, and
    a lack of treatment can cause significant harm to the patient.
    Examples of tracer conditions include otitis media, appen-
    dectomy, caesarean section, and hysterectomy. These con-
    ditions, if evaluated in terms of incidence and actual chart
    review, can provide useful insights into departmental medi-
    cal standards. Incident reports by nursing staff and nosoco-
    mial infections are examples of the functioning of the tracer
    condition concept.

    Incident reports in hospitals are designed to determine
    the causes of errors, so that remedial action can be taken
    and similar events prevented. Tracer condition studies have
    become such an accepted part of modern health manage-
    ment that the absence of an organized review system could
    be considered a serious structural flaw in a health service,
    requiring remedial action.

    Setting Standards

    Standards recommended by independent professional
    organizations or by advisory committees appointed by
    ministries of health can play important roles in defining
    standards of care for specified conditions. In addition,
    organized professional bodies can issue practice guidelines
    or help governments or health care agencies to develop
    standards or algorithms for management of specific topics
    and conditions.

    Specifying standards for preventive care, such as for
    infants and adults, assists local health authorities in plan-
    ning and evaluating services. The American Academy of
    Pediatrics (AAP) has an extensive professional committee
    structure that publishes periodic guidelines for pediatricians
    on a wide variety of infant and child topics including nutri-
    tion, immunization, prevention of anemia and lead toxicity,
    child safety, and school health. Mandatory preventive care
    for newborns includes eye care and vitamin K injection in
    the USA (see Chapter 6). Mandatory immunization require-
    ments for school entry and for health care personnel are dis-
    cussed in Chapter 4.

    The American Public Health Association (APHA) pub-
    lishes the Control of Communicable Diseases Manual, now
    in its nineteenth edition (2008). It is the authoritative US
    manual on this topic. The AAP’s Red Book on infectious dis-
    eases is used across North America by pediatricians in clini-
    cal practice. These organizations and their counterparts in
    obstetrics and many other clinical fields directly relevant to
    public health continually update practitioners and policy per-
    sonnel in the “state of the art” or “gold standard”, discussed
    previously. This constitutes a professional self-guidance sys-
    tem in standards. Managed care and other health provider
    systems also issue guidelines for member practitioners that
    serve to maintain standards of service.

    The wide use of treatment protocols and scoring systems
    in hospital medicine helps to define standards of care in a
    measurable way. The Apgar score for rating newborn sta-
    tus has been a standard in hospitals worldwide for decades,
    helping to standardize infant assessment and care. The
    APACHE (Acute Physiology And Chronic Health Evalua-
    tion) scoring system is used widely to assess the chances
    of survival of patients admitted to intensive care units and
    to compare outcomes, for example, between teaching hos-
    pitals and community hospitals. It is also used in assessing
    patient outcomes with different modes of treatment. Scor-
    ing systems are also used in community health care, as in
    risk scoring for pregnancy care (see Chapter 6).

    Algorithms and Clinical Guidelines

    Algorithms are decision trees or a systematic series of deci-
    sions based on the outcomes of previous decisions, tests, or
    findings. Derived from operations research, this approach
    applied to medicine identifies all available choices (e.g.,
    exposed versus non-exposed) and follow-up decisions
    based on findings from each previous option substantiated
    by observation. It is often presented graphically like the
    branches of a tree, showing the alternatives and subsequent
    decisions to be made.

    A clinical algorithm is a systematic process defining
    a sequence of alternative, logical steps depending on out-
    comes of previous ones, incorporating clinical, laboratory,
    and epidemiological information, applied to maximize ben-
    efits and minimize risks for the patient. It gives the provider
    a review of the relevant literature and recommended stan-
    dards of practice on a particular topic for preventive care
    or case management. These guidelines are usually arrived
    at by consensus of multidisciplinary working groups taking
    into account published studies on the topic. The guidelines
    may suggest that some procedures should not be carried out
    routinely.

    Clinical guidelines are meant to establish accepted stan-
    dards of care and may have important economic implica-
    tions. Medical Letter, published by the Consumers’ Union,

    vant studies. It represents a balanced, updated view of medi-
    cal practice and summaries of current literature, reviewed
    by respected, experienced, and competent medical authori-
    ties. Clinical practice guidelines are produced by hundreds
    of professional, medical, and governmental agencies in
    order to standardize and improve medical care.

    Clinical and preventive care guidelines are helpful
    in clinical practice and in preventive medicine. They are
    increasingly used in managed care environments to assure
    standards, quality of care, and cost-effectiveness as well as
    legal protection. Guidelines for preventive medicine and
    public health practice are also part of the process of pro-
    moting the quality of individual and community health,
    as discussed in Chapter 11. Annual revision of the infant

    immunization program, discussed in Chapter 4, is a prime
    example, as is the set of guidelines for preventive care for
    adult health maintenance in Table 15.5.

    The issue of application of current scientific knowledge
    for population health is a continuing struggle for recognition
    of the prime importance of health promotion and preventive
    care for health of a population. The selection of priorities in
    use of resources is vital especially in the many developing
    countries that are in various stages of economic development,
    or which have abundant income from natural resources such
    as oil and minerals. Implementation of programs designed to
    achieve the MDGs can help to serve this purpose.

    Public health standards and clinical practice guidelines
    are an increasing part of quality improvement. It is impor-
    tant, however, that they are developed as best practices and

    influenced as little as possible by commercial interests of
    drug or vaccine manufacturers. The proliferation of such
    guidelines by health authorities or professional associations
    of the USA, the UK, Canada, Australia, and other countries
    indicates a wide consensus on the importance of such writ-
    ten standards, guidelines, or “best practice” statements. The
    recommended childhood immunization program put for-
    ward annually by the CDC in conjunction with the AAP and
    other professional organizations is an example of such best
    practices and is accepted by health insurers and providers as
    the gold standard in this field. The concept of promotion of
    quality in health care and the adoption of current scientific
    standards are global issues and an integral part of the New
    Public Health (Box 15.6).

    BOX 15.6 EISC: The Excellence in Science Committee
    of the Centers for Disease Control and Prevention

    The Excellence in Science Committee (EISC) promotes the
    Centers for Disease Control and Prevention’s (CDC’s) sci-
    entific infrastructure and facilitates communication and
    collaboration that enhance scientific areas and activities
    needed for state-of-the-art conduct of science. EISC serves as
    a consulting body for science-related issues and makes rec-
    ommendations to the CDC to foster, support, and protect an
    environment for the promotion of scientific integrity, quality
    assurance, and the rapid dissemination of scientific innova-
    tions, technology, and information, with the ultimate goal of
    improving public health.

    EISC’s specific functions include:
    l promoting and protecting the scientific infrastructure
    l providing a forum for information exchange among

    administration, directors for science, and liaison work-
    ing members/groups

    l communicating science-related issues to the CDC and
    related scientists

    l promoting professional development and training
    l recognizing and rewarding quality science
    l acting as an advocate for scientific resources

    The Canadian Province of Saskatchewan Health Ser-
    vices Utilization and Research Commission publishes peri-
    odic reports presenting consensus positions of panels of
    medical faculty, clinical specialists in pathology and physi-
    cal medicine, and public health specialists in nutrition, com-
    munity health, and epidemiology. Its reports are circulated
    widely and serve to update medical practitioners, reduce
    unnecessary testing, promote appropriate use of laboratory
    and other diagnostic procedures, and provide standards of
    care for individual patients and community services, such
    as long-term care facilities and home health agencies.

    The Canadian Medical Association issued its Handbook
    on Clinical Practice Guidelines in 2007, based on a system-
    atic review of the literature, interviews of key professionals,
    consensus conferences, and continuing evaluation of both
    process and content of such guidelines. The Guideline Inter-
    national Network (GIN) Fourth International Conference,
    held in Toronto in 2007, involved experts in national and
    international practice guidelines from 31 countries to share
    experience and concepts in this ongoing field. The GIN
    library contains more than 6600 (by October 2012) guide-
    lines, evidence reports and related documents, developed or
    endorsed by GIN member organizations (GIN, 2012).

    An Institute for Clinical Evaluation (ICES) organization
    at the University of Toronto, established in 1992 with core
    funding provided by Ontario’s Ministry of Health and Long
    Term Care, is mandated to conduct research that contributes
    to the effectiveness, quality, equity, and efficiency of health
    care and health services in Ontario. ICES uses an interdis-
    ciplinary research approach to health care, health services,
    and health policy.

    The American College of Cardiology (ACC) provides a
    framework of evidence-based clinical statements and guide-
    lines developed by leaders in the field of cardiovascular med-
    icine with continuing adoption of new scientific information
    and experience in many aspects of this field (ACC, 2012).
    Many professional organizations such as the AAP, American
    Congress of Obstetricians and Gynecologists (ACOG), UK
    Faculty of Public Health, and European Society of Cardiol-
    ogy produce clinical guidelines which are updated regularly
    to provide physicians and health systems managers with
    current consensus on state-of-the-art standards, such as the
    European Society of Hypertension Guidelines released in
    2013 (i.e., less than 140 mm. systolic for all).

    The US Health Care Financing Administration (HCFA),
    Center for Medicare & Medicaid Services (CMS), and
    National Institutes of Health (NIH) have consensus pro-
    grams to develop guidelines that are widely disseminated
    and set standards of practice. In 1977, the NIH issued its
    first consensus paper on breast screening for cancer, and
    this has been followed by many other topics each year
    since. The AHRQ also produces research related to efficacy
    of current and new practices and training material to pro-
    mote their diffusion across the US health system. Cochrane

    http://www.cdc.gov/od/science/excellence/

    794

    reviews and the Cochrane Library provide high standards of
    literature reviews and meta-analysis on many topics which
    serve to guide practitioners and policy makers in current
    standards. The US Healthy People 2020 project provides
    gold standards for preventive care which serve clinicians,
    public health practitioners, and health planner standards
    for their work. Evidence-based consensus guidelines were
    issued on the following topics: breast cancer screening
    for women aged 40–49, interventions to prevent HIV risk
    behavior, management of hepatitis C, genetic testing for
    cystic fibrosis, acupuncture, and effective medical treat-
    ment for heroin addiction.

    Clinical guidelines are increasingly being promoted
    by professional, governmental, and managed care orga-
    nizations with the purpose of promoting rational use of
    health care resources and at the same time promoting
    standards of care to incorporate good standards of clinical
    practice. Clinical practice guidelines are now common in
    the practice of primary care, mental health, and clinical
    specialties. The University of Southern California’s list
    of clinical guidelines website (http://medicine.ucsf.edu/)
    provides access to hundreds of websites for such practice
    guidelines.

    Clinical guidelines provide practicing doctors, peer
    review committees, health care managers, managed care
    companies, governmental bodies, and professional organi-
    zations with channels to set standards of practice and expec-
    tations of care standards. Legal aspects of health care also
    increasingly recognize the importance of clinical guidelines
    where committees of appropriate medical professionals
    convene and set out average or minimum standards of care
    for defined clinical entities. Thus, peer-reviewed guide-
    lines set an appropriate standard (a silver if not a gold stan-
    dard) for judging malpractice or adequate practice. Clinical
    guidelines should be under periodic review and subject to
    critical discussion and updating using the Cochrane review
    methods of literature review and analysis. Promotion by
    advocacy or special interest groups can be constructive,
    but the influence of drug companies can be insidious and
    reduce the professional objectivity of such reviews and their
    recommendations, a concern that must be carefully moni-
    tored and continuously kept in mind as a potential compro-
    mising bias.

    The AAP produces policy statements, practice param-
    eters, and model bills which have a wide distribution and
    influence; they are published in the academy’s journal, Pedi-
    atrics. The AAP clinical practice guidelines issued include
    diagnosis and treatment of urinary tract infection in febrile
    infants and young children, long-term treatment of the child
    with simple febrile seizures, management of acute gastroen-
    teritis in young children, management of otitis media with
    effusion in young children, and others. The policy state-
    ments of the AAP cover a wide range of topics including
    use of bicycle helmets, 55 mile per hour maximum speed

    The New Public Health

    limits, folic acid for the prevention of neural tube defects,
    and ethics in the care of critically ill infants and children.
    AAP guidelines are valid for 5 years only and are reissued
    or reconfirmed in order to keep up to date and to incorporate
    new or revised knowledge into practice standards.

    Empirically derived, peer-reviewed, regularly updated
    guidelines have become an appropriate standard for prac-
    tice and for judging malpractice, as well as balancing qual-
    ity and cost-effectiveness. Clinical guidelines may become
    restrictive, but they help to reduce practice by whim and
    unsubstantiated belief to improve the quality of care over-
    all. In large health care organizations they provide a basis
    for continuing education for staff and advancement of stan-
    dards of the organization.

    The Community Guide produced by the CDC provides
    an excellent source of evidence-based advice for community
    programs. It serves the needs of public health professionals,
    health care providers, legislators and policy makers, research-
    ers, community-based organizations, employer–employee
    groups, and other purchasers of health services. The guide
    covers a wide range of health issues including alcohol, can-
    cer, diabetes, mental health, motor vehicle safety, nutrition
    and obesity, oral health, physical activity, pregnancy, sexual
    behavior, social environment, substance abuse, tobacco, vac-
    cines, violence, and workplace health issues.

    In 1999, the UK National Health Service (NHS) estab-
    lished the National Institute for Clinical Excellence (NICE)
    as an independent organization to provide guidelines for
    public health, health technologies, and clinical practice
    guidelines for specific conditions. The Health Development
    Agency of the NHS was included in the NICE organization
    in 2005. Now called the National Institute for Health and
    Care Excellence, NICE publishes guidelines that provide a
    helpful basis for clinical practice and public health as well
    as other areas in the NHS to update the services provided.
    Topics for public health include smoking and tobacco con-
    trol, diet and obesity, exercise and physical activity, sexual
    and mental health, and alcohol.

    ORGANIZATION OF CARE

    Administrative and financing systems are essential ele-
    ments of quality assurance. They can be designed to pro-
    mote standards of care and to reduce fiscal incentives that
    foster excess supply and overservicing. The organization
    of financing health care has important implications for
    quality, technology, and ethical issues in the New Public
    Health.

    Diagnosis-Related Groups

    DRGs, discussed extensively in Chapter 11, were developed
    in the 1960s as an alternative way of paying for hospital care
    in order to encourage shortened lengths of stay. Experience

    http://medicine.ucsf.edu/

    Chapter 15 Health Technology, Quality, Law, and Ethics

    with payment by days of care (per diem) showed that it pro-
    moted unnecessary, lengthy, and potentially dangerous use
    of hospital care, an important factor in the rapid escalation
    of costs in the health system. DRGs were adopted for pay-
    ment for Medicare beneficiaries in the USA in 1983 and
    later became the standard method of payment for all insur-
    ance systems.

    In the DRG system the insurer pays the provider hos-
    pital for a procedure or diagnosis rather than the number
    of days of stay in hospital. This has led to a large reduc-
    tion in hospital days of care and a remarkable growth in the
    number of surgical procedures done on an outpatient basis.
    Since the introduction of DRGs, outpatient surgical proce-
    dures have grown from less than one-fifth to more than half
    of inpatient surgical cases. Outpatient surgery is safer for
    the patient and less costly to the insurer. DRGs have gradu-
    ally been adopted as a case payment system for reimbursing
    hospitals in most developed countries.

    The DRG system is widely considered to promote qual-
    ity of care as an active process focusing on quickly address-
    ing the diagnosis and management of the patient with rapid
    mobilization of treatment and return home. Critics of this
    system allege that DRGs encourage inappropriate early
    discharge of patients before optimal patient education and
    follow-up care have been provided, but long length of hos-
    pital stay has not been shown to improve patient outcomes.
    Critics also suggest that this may promote altering diagno-
    ses to higher cost units of service. Others think that DRGs,
    by reducing length of stay, have turned hospitals into inten-
    sive care units with ultra-sick patients. Despite these issues,
    the trend towards short hospital stays and newer approaches
    to active treatment seems to be compatible with better care
    and improved outcomes, according to some measures. The
    rapid decline in mortality rates from coronary heart disease
    is thought to be due in large part to the activist treatment
    approach, with lengths of stay of 1 week or less for acute
    myocardial infarction compared to 6 weeks on average up
    to the 1970s.

    Managed Care

    Managed care systems developed in the USA in response
    to rapid cost escalation for health care and the successful
    experience of HMOs. Managed care is based on the con-
    cepts of resource management, and quality assurance with
    rationalized use of technology. The system developed over
    time with checks and balances to provide comprehensive
    care at lower cost than traditional fee-for-service systems
    by discouraging excessive utilization without compromis-
    ing quality of service. Managed care systems include tradi-
    tional HMOs and various other organizations which employ
    physicians or are made up of independent physicians work-
    ing together who own or contract for hospital services (see
    Chapter 10).

    795

    HMOs, both for-profit and not-for-profit, and man-
    aged care itself, have been widely criticized as excessively
    limiting patient access to appropriate care in the interest
    of cost containment. The 2010 PPACA (Obamacare) is
    promoting development of newer innovations including
    patient-centered medical homes (PCMH), accountable
    care organizations (ACOs), and population health man-
    agement systems (PHMSs), and early evidence shows that
    these models are quality management approaches for inte-
    grated primary and hospital patient care (see Chapter 11).
    Obamacare is a highly politicized and much debated topic
    in the USA; it seems likely to make a very big difference
    in coverage and fair practices of insurance with lower
    costs of private insurance.

    District health systems in the UK, the Scandinavian
    countries, and the post-Soviet model of health care incor-
    porate organizational and financial linkage between care
    systems and funding from tax sources. HMOs, sick benefit
    funds, and district health systems provide both prepayment
    and health services. Even in traditional private health insur-
    ance systems, the insurer is increasingly taking on the role
    of regulating reimbursement for medical services in order to
    contain costs and curb abuses by providers. In this context,
    emphasis is placed on maintaining health, preventive care,
    and financial incentives to efficiency in overall care. Clini-
    cal indications, utilization review, and organizational and
    professional standards are now becoming accepted parts of
    the health insurance milieu.

    The competition between hospitals for referrals from
    managed care plans in the USA has created a market
    situation in which a high proportion of hospital beds are
    empty, and in which mergers or closures of hospitals
    are common. Closures or reductions in hospital bed sup-
    ply are also occurring in the UK and in most industrial-
    ized countries of Europe.

    PERFORMANCE INDICATORS

    Performance indicators are measures such as morbidity,
    mortality, functional status, or immunization rates in a com-
    munity, used to monitor the functioning of a health service.
    Routinely collected statistics are analyzed to compare per-
    formance against objectives, help monitor efficiency and
    effectiveness, point out problem areas within the service,
    and plan new health programs. This method is based on the
    use of the concept of management-by-objectives in health
    administration to promote achievement of national health
    targets.

    The UK has a strong tradition of mapping diseases as a
    basis of epidemiological analysis and has applied this strat-
    egy to mapping of performance indicators to assess health
    care performance. The UK financing system is based on
    capitation adjusted by standardized mortality rates on the
    premise that mortality rates standardized and compared to

    796

    the national average serve as indicators of need. In this way,
    the approach helps to promote equitable funding among
    wealthy and poorer regions of the country, and thereby
    improve services in areas of greater need.

    Performance indicators were introduced into the NHS
    during reforms of the late 1980s, providing a series of
    outcome or performance measures that are used to adjust
    payments allocated on a per capita basis to district health
    authorities. These authorities can be penalized for low rates
    of immunization, whereas general practitioners receive
    incentive payments for full immunization coverage. The
    result was a rapid improvement in immunization coverage
    of infants and children compared to rates in the previous
    decade. Incentive payments in many countries encourage
    women to go to hospitals for delivery or to attend prenatal
    care by making social maternity grants conditional on seek-
    ing care.

    Use of performance indicators requires the development
    of health information systems with district health profiles
    to provide ongoing monitoring of health indicators in a dis-
    trict, compared to regional and national rates and targets.
    Health profiles help to establish and monitor the prevalence
    of chronic disease and measure the impact of health ser-
    vices. This enables the study of the performance of preven-
    tive and curative services, such as managing hypertension
    to reduce the incidence of strokes and related conditions.
    There are criticisms of performance indicators alleging a
    potential for manipulation and abuse of health intervention
    measures when the financial incentives are used for a spe-
    cific activity. However, financial incentives are part of the
    DRG system and have been successfully used in the UK to
    improve vaccination coverage and implementation of other
    preventive health practices by family physicians. In Israel in
    2007, payments to hospitals provided a bonus for surgical
    interventions for hip fracture within 48 hours of the event,
    resulting in a marked rise in early intervention and a reduc-
    tion in mortality from hip fractures.

    CONSUMERISM AND QUALITY

    With decentralization and the growth of managed care,
    health systems must increase their attention to the attitudes
    of the consumer. Quality is, in part, how the client per-
    ceives the system, and how the system meets client needs
    in an acceptable manner, where privacy, dignity, the right to
    know, and the right to a defined set of services are protected.
    However, the rights of the client are not unlimited. A public
    or private health plan has the duty to manage the basket of
    services responsibly, which includes limitations such as in
    access to specialist services.

    Patients’ rights and consumer protection in health care
    often (but not always) include the right to select and change
    a health care provider, as well as the right to receive high-
    quality care for a designated range of services. The UK NHS

    The New Public Health

    issued a patient’s Charter of Rights during the 1990s, which
    is perhaps idealistic and may not be actualized in practice,
    but still outlines an ideal of value both for practical applica-
    tion and for legal rights. The consumer’s formal protection
    includes the right to complain and to seek redress of grievance
    and compensation for injury suffered from neglect or incom-
    petent care (Box 15.7). In North America and Europe, there
    are at least four models of defining the rights of patients: the
    paternalistic model, the informative model, the interpretive
    model, and the deliberative model (WHO, 2012). Many new
    charters have been established such as data protection, end-
    of-life care, mental health, access to health services, quality
    of care and care giving environment, nationally approved
    treatments, drugs and programs, respect, consent and confi-
    dentiality specific to the UK and in Canada, New Zealand
    and other countries. The new US federal Affordable Care Act
    of 2010 (PPACA) includes a large element of patient’s rights
    protection, as discussed in Chapter 10.

    The patient or consumer of health care needs to be
    informed and conscious of health care costs if efforts to
    restrain cost increases are to be effective. Public attitudes
    are vital in terms of self-care, demands on the health service,
    and limitations to the potential of health care and resources
    for health care. The media and consumer organizations can
    play important roles in advocacy for health, in raising pub-
    lic consciousness of self-care, and as watchdogs on abuses.

    Consumer acceptance is manifested through choice of
    health plan and practitioner, or by seeking alternative care

    Chapter 15 Health Technology, Quality, Law, and Ethics

    privately when service is unacceptable because of quality or
    style. Erosion of confidence in a public system of care can
    lead to a two-tier system with the public system serving the
    poor and a private parallel system serving the middle and
    wealthy classes. Such a division can seriously undermine a
    public system unless it is addressed by improving the qual-
    ity and manner of the service and by establishing supervi-
    sion and limitations on public and private practice.

    The growing inequality caused by the rise of private
    practice outside a national health care system is a chronic
    problem in the UK’s NHS, in Israel’s health system, and in
    many countries developing their health systems through par-
    allel public and private care. The issue is also surfacing in
    the USA in the transition to managed care with its inherent
    limitations of choice for people insured through their place of
    work or covered under the Medicare and Medicaid programs.

    The PPACA requires insurance companies to accept any-
    one requesting cover without restrictions due to prior con-
    ditions or high expenses for serious conditions, and without
    other forms of discrimination common in the past. It also
    includes provisions for coverage of preventive care services
    and incentives for quality improvement. Extra billing, banned
    in Canada’s national health insurance plan, is a recurring
    issue with the medical profession in some provinces.

    Consumer knowledge, attitudes, beliefs, and practices
    are part of the health system, from health promotion to
    tertiary care. Informed and health-conscious consumers
    are stronger partners in the health system in achieving
    improved health than an ill-informed and apathetic public,
    so that health education and health promotion are funda-
    mental to modern public health. The role of the consumer
    in health care is unique in that there is a significant infor-
    mation asymmetry between the consumer and provider.
    Health education programs and wide use of the Internet
    increase access to health and medical information, but this
    gap can never completely be eliminated. Patients may use
    their power as consumers to demand inappropriate care,
    such as unnecessary surgery or antibiotics when clearly
    not indicated, because of their preference for interven-
    tion and action over watchful waiting. However, there is
    an equal or perhaps greater danger of provider-induced
    demand for repeated and possibly unnecessary interven-
    tions that may be related to methods of paying the doctor
    or the hospital. The traditional doctor–patient relationship
    is still an important factor for the interests of patients and
    their health. A still effective method of having an individ-
    ual quit smoking is a brief but stern lecture by the family
    physician.

    THE PUBLIC INTEREST

    Population-based interventions are often more effective
    and less costly ways to reduce morbidity and mortal-
    ity than individual prevention or treatment services. A

    797

    population-based preventive program may require behav-
    ior change by the individual, such as in mandatory seat
    belt and motorcycle helmet enforcement or banning smok-
    ing in public places. Fortification of flour, milk, and salt
    with essential micronutrients is a well-established public
    health measure. There is an element of compulsion in this,
    with the social gain usually considered to be sufficiently
    important to outweigh individual rights. Immunization
    is for the protection of individuals but also for the popu-
    lation, so that refusals to immunize children and adults
    can cause injury to others. Herd immunity is protective
    of people who are at high risk. Mandatory immunization
    for school entry in the USA has been effective in increas-
    ing coverage to levels akin to the most advanced health
    systems, over 95 percent coverage. Refusals and failure to
    harmonize immunization policies in Europe have resulted
    in mass epidemics of measles, rubella, and mumps in
    recent years.

    There is often a delicate balance between community
    rights and individual rights which can lie at the heart of
    many controversies in modern public health and health
    care, ranging from chlorination or fluoridation of com-
    munity water supplies to managed care systems for
    health services. Women’s rights, gay rights and abortion
    are highly controversial and politicized in the USA, and
    in many other countries. The differences can become
    extreme and the source of international strife, such as in
    the movement to promote fundamentalist Sharia law in
    many countries that are severely restrictive of women’s
    and minority rights.

    In public health, issues should be examined on their
    merits, especially in terms of what is accepted as good pub-
    lic health practice, based on evidence from clinical trials,
    documented experience, and best practices in other coun-
    tries. The evidence of successful public health measures in
    improving individual and collective health status is power-
    ful, yet must always be balanced within the context of indi-
    vidual rights and the public interest. The ethical issues of
    individual and community rights of public health are dis-
    cussed later in this chapter.

    TOTAL QUALITY MANAGEMENT

    Total quality management (TQM), as discussed in Chap-
    ter 12, was adapted from business management theory and
    practice to health care in the 1990s and provides a basis for
    promoting continuous improvement in health care systems.
    TQM involves everyone in the system, from all levels of
    management to production or service personnel and sup-
    port staff, and thus helps to raise staff morale because of the
    shared involvement. Health is provided through multidisci-
    plinary groups which need to approach problems with open
    and shared scientific inquiry and hypothesis formation, test-
    ing, and revision to find operational solutions to problems.

    798

    Electronic health records and information technology pro-
    vide many new opportunities to improve patient care and
    data systems for monitoring the health status of population
    groups for process and outcome measures, or health targets,
    such as immunization coverage, or screening compliance
    for colon, cervical, or breast cancer, as measures of perfor-
    mance in primary care. Information technology adds a great
    deal of capacity for quality monitoring and improvement
    measures.

    TQM incorporates statistical methods, comparing varia-
    tions in patterns of service or use of resources. It employs
    epidemiological methods to draw conclusions for policy
    needs. It looks for continuous improvement, encouraging
    cooperation, and motivation to achieve common goals of
    service and client satisfaction. Psychological theory helps to
    foster higher levels of motivation, with early identification
    and resolution of conflict. Leadership is shared, and there is
    a basic need for cooperation. Cost and quality are interre-
    lated, as poor quality leads to waste, inefficiency, and dis-
    satisfaction of both clients and staff. High-quality, humane,
    and effective services are especially important in a competi-
    tive environment where clients have the right to choose and
    where costs and efficiency are factors in the well-being and
    indeed the survival of institutions.

    Medical care is increasingly practiced in larger health
    care organizations. To provide technically competent
    medicine is not by itself sufficient. The patient’s rights
    and sense of personal worth are also of great importance.
    Financial incentives can be effective in redirecting health
    care priorities, such as in reducing hospital length of
    stay and admissions, but may result in the patient or the
    family feeling that they are not receiving the best care.
    DRGs, HMOs, and other organizational and funding sys-
    tems meant to increase efficiency of care may have the
    effect of alienating patients from a health care system.
    Staff attitudes towards patients are important for client
    satisfaction. The service must include ready access to
    a continuum of supportive services, such as home care
    and counseling, so that the patient and family do not feel
    abandoned by the system.

    A byproduct of TQM is continuous quality improve-
    ment (CQI), by which institutions wishing to improve qual-
    ity train and empower the staff to work in teams to assess
    their own performance and seek solutions to problems in
    their operational unit. People of different ranks and profes-
    sions work in a network organization as well as in a tradi-
    tional hierarchical organization in which rank and seniority
    provide authority. This community of practice is important
    for staff morale and a shared sense of responsibility for the
    patient and the institution.

    CQI involves multidisciplinary approaches, not only
    to review problems but also to seek better ways of func-
    tioning and improving consumer satisfaction. The process
    includes all those involved in providing care, support ser-
    vices, and administration of a department, hospital, clinic,

    The New Public Health

    or community health program. This is not only professional
    self-policing but a method to find better ways of meeting
    needs and using resources. The involvement of all provid-
    ers improves motivation and promotes a sense of common
    purpose in the organization.

    Applying these principles in a health care setting can
    take many forms. Selection of topics by TQM/CQI com-
    mittees in a hospital or another health facility may be
    based on surveys or interviews with staff, patients, or
    management. Satisfaction surveys among women follow-
    ing delivery in an obstetrics unit could point out remedi-
    able problems. An obstetrics department may be faced
    with issues related to high or low volume of deliveries,
    staff training, equipment and supplies, communica-
    tion among staff, and among staff and patients and their
    families, cleanliness, sterile technique, staff satisfaction,
    client satisfaction, and many others. The team looking
    at such a problem should be multidisciplinary, and the
    emphasis should be on client attitudes and satisfaction.

    Examination of the function of an emergency depart-
    ment in a hospital would similarly look at many functional
    and attitudinal aspects of the service including staff atti-
    tudes, training needs, waiting times, consultation ser-
    vices, and others. Addressing waiting times, for example,
    can lead to ways to reduce these substantially, improving
    both client satisfaction and the efficient management of
    the emergency department. Any service is there to serve
    patients and the community. A service is not primarily for
    the benefit of the staff, but staff satisfaction and morale are
    essential for successful service to clientele. CQI can also
    be applied to assessing and improving compliance with
    clinical guidelines or evidence. An example is assessing
    the proportion of diabetics whose hemoglobin A1c (HbA1c)
    is measured at least twice annually, who have eye and
    feet examinations regularly, or whose blood pressure is
    managed with an angiotensin-converting enzyme (ACE)
    inhibitor.

    The European Region of the WHO and the national
    medical associations in Europe agreed in 1995 that medi-
    cal associations should take leading roles in programs of
    CQI to achieve better outcomes of health care in terms of
    functional ability, patient well-being, consumer satisfac-
    tion, and cost-effectiveness. This is in keeping with the
    European Region’s Health for All targets: there should
    be structures and processes in all member states to
    ensure continuous improvement in the quality of care and
    appropriate development and use of health technolo gies.

    The introduction in the 1990s of general practitioner
    fundholding for hospital care for patients on the general
    practitioners’ roster in the UK encouraged the hospital to
    maximize patient satisfaction with the care system. This
    promotes application of CQI to improving the quality and
    acceptability of care. Similarly, performance indicators
    provide regional and district health authorities in the UK
    with tools for CQI approaches. The UK NHS established

    799Chapter 15 Health Technology, Quality, Law, and Ethics

    The National Institute for Clinical Excellence (NICE), estab-
    lished in 1999, has a mandate to review health service treat-
    ments and effective therapies that should be commissioned
    and made available within the National Health Service (NHS)
    throughout England and Wales. The mission statement for
    NICE is that it “contributes to better health around the world
    through the more effective and equitable use of resources”.
    In 2005 NICE was revised to include reviews of public health
    interventions, and its mandate was expanded to include quality
    standards for the English social care sector (English Health and
    Social Care Act of 2011). Now renamed the National Institute
    for Health and Care Excellence, NICE operates as a statutory
    independent special health authority in England and Wales.
    Commissioning bodies of the NHS are required to observe its
    recommendations. Guidance can be used by the NHS, local
    authorities, employers, voluntary groups, and anyone else
    involved in delivering care or promoting well-being.

    NICE recommendations are respected elsewhere in the
    UK, but are not mandatory; in Scotland NICE recommen-
    dations are published after further review by NHS Quality
    Improvement Scotland (for health services issues) and by NHS
    Health Scotland (for public health recommendations). NICE
    recommendations are respected worldwide, including by the
    European Commission and by national governments; NICE
    International is a section of NICE established to meet non-UK
    needs (e.g., evaluating rural health programs in China).

    An independent committee including lay representation
    advises on priorities for NICE consideration but final deci-
    sions on topics referred to NICE are made by the Department
    of Health. When making recommendations to the NHS on
    which services (e.g., treatments) should be provided routinely,
    it calculates the cost-effectiveness of treatment for each quality-
    adjusted life year (QALY) of health gain purchased.

    NICE publications include guidance on 374 interventional
    procedures, 270 technology appraisals, 162 clinical guide-
    lines, and 43 public health topics. From this latter group, some
    examples include:
    l Prevention of cardiovascular diseases (2010) – provides

    evidence of effectiveness of population-based prevention
    programs as more effective than programs aimed at high-
    risk groups.

    l Alcohol dependence and harmful alcohol use (2011) –
    summarizes all NICE guidance; designed to inform mem-
    bers of the public as well as health professionals.

    l Preventing type 2 diabetes through population and com-
    munity interventions (2011) – provides guidance to gov-
    ernment departments, the commercial sector, health
    service organizations, and non-governmental organiza-
    tions on integration of public policy to prevent obesity, and
    reduce diabetes prevalence and complications.

    l Preventing uptake of smoking by children and young peo-
    ple (2008) – document to advise local health service com-
    missioners; identifies target populations, reviews campaign
    messages, and provides recommendations for the mass
    media and retailers.

    l Promoting mental well-being at work (2009) – guidance
    aimed at employers; reviews evidence in the field and rec-
    ommends strategic approaches by firms, opportunities to
    promote well-being and assess risk, and systems of flexible
    working.

    l Preventing unintentional injuries among under-15s in the
    home (2010) – reviews evidence and makes recommenda-
    tions to local authorities and related agencies on training
    an appropriate workforce, advises government to fund cur-
    ricula development, and indicates to the NHS appropriate
    surveillance and treatment services.
    NICE is often criticized (especially by the pharmaceuti-

    cal industry) for the time taken to carry out investigations of
    new treatments. It is also criticized by relatives of patients with
    “glamorous” conditions (e.g., cancer) for not approving drugs
    that might extend life by only 4–6 weeks, and perhaps approv-
    ing instead new psychiatric therapies. The current government
    has recently sought to overrule some of these NICE recommen-
    dations in England. However, NICE methods and recommen-
    dations are held in high repute, within the UK and beyond.

    BOX 15.8 The UK’s National Institute for Health and Care Excellence (NICE)

    NICE as an independent body to promote “national
    guidance on promoting good health and preventing and
    treating ill-health”. NICE produces guidance in three
    areas:

    l public health – guidance for those working in the NHS,
    local authorities and the wider public and voluntary sector
    on promotion of good health and the prevention of disease

    l health technologies – guidance on use of new and
    existing medicines, treatments and procedures within
    the NHS

    l clinical practice – guidance on appropriate treatment
    and care within the NHS of people with specific dis-
    eases and conditions.

    NICE guidelines are recommended practices with the
    objective of reducing ineffective practices. During 2007,
    guidelines were issued on topics including asthma, derma-
    titis, caesarean section, chronic obstructive lung disease,
    depression (in children and adults), eating disorders, fertil-
    ity, contraception, multiple sclerosis, post-traumatic stress
    disorder, and diabetic foot care (Box 15.8).

    The New Public Health

    The USA has a number of government and independent
    organizations dedicated to improving quality in health care
    systems. The CDC and the Institute of Medicine of the US
    National Academies of Science play active roles in promot-
    ing research quality and methods of CQI in the US health
    care system. Canada is also very active in this regard, hav-
    ing national and provincial institutes for the evaluation of
    clinical effectiveness and clinical guidelines, and so too are
    European countries (Box 15.9).

    PUBLIC HEALTH LAW

    Public health workers need knowledge of government
    structure and public health legislation as basic to their pro-
    fessional work to understand their responsibilities, powers
    and liabilities. Law consists of a system of rules, regula-
    tions, and orders that govern the behavior of individuals
    and of society. Law represents the consensus of a society, as
    enacted by an elected legislature, put into effect by the exec-
    utive branch of government, and interpreted by the courts
    as need be from time to time. The legislative and execu-
    tive branches are separate under the US Constitution, but
    the two are united in the parliamentary system (Box 15.10).
    The authority, responsibility, and power to provide for and
    protect the public health are basic functions of a sovereign
    government, which may be delegated to another level of
    government (higher or lower) or even a non-governmental
    agency. The constitution of a sovereign government states
    explicitly or implicitly that responsibility, but accepted
    practice and court decisions (i.e., the common law) define
    the powers of the national, state, or local government to
    monitor and protect the health of its citizens.

    In the USA, national legislation is enacted under the
    powers of the federal government, namely to regulate inter-
    state commerce and the power to tax and spend for the
    general welfare. State legislation is enacted under the basic
    power of the state to protect the health, welfare, and safety
    of its citizens. Under these federal and state powers, a wide
    range of health legislation and regulations is enacted affect-
    ing public health, labor, and occupational health and safety,
    environmental controls, public welfare, and the financing
    of health services, agriculture, food, drugs, cosmetics, and
    medical devices. Public health law relies on a wide range of
    constitutional, statutory, administrative, and judicial deci-
    sions in both civil and criminal actions. Appropriation of
    funds is a legal act of legislative bodies to achieve objec-
    tives directly or indirectly by financial incentives.

    Categorical programs may be directed to specific issues
    such as combating TB and promoting immunization or for
    work to combat NCDs such as diabetes, or in improving
    standards of facilities, and in providing health care services.
    The regulatory, enforcement, policing, and punitive func-
    tions of public health laws have evolved over many decades
    and in many countries lack clear definition. In the USA,

    801Chapter 15 Health Technology, Quality, Law, and Ethics

    In federal nations, political authority is divided between two
    autonomous sets of governments, one national and the other
    subnational. Both operate directly with the people in their juris-
    diction based on a constitutional division of power between
    the national government, which exercises authority over the
    whole national territory, and state or provincial governments
    with independent authority within their own territories. The
    constitution is the supreme law of a country. It sets out the
    divisions of governmental powers including statutory authority,
    administrative, natural resources, and taxation between federal
    and state levels of government.

    A federal legislature or congress makes the law of the land,
    but is subject to rulings of a Supreme Court as are state and
    local governments. State or provincial governments in a fed-
    eral system have functions set out in the Constitution. They
    also have elected legislatures, and executive branches with
    taxing, regulatory, and punitive powers. Local governments
    for county, municipal, or city governments also have dele-
    gated taxing and regulatory powers including those of public
    health.

    Canada, the USA, Brazil, Australia, India, and Argentina
    are organized on a federal basis. Federal countries also include
    Austria, Germany, Malaysia, Mexico, Nigeria, Switzerland, and
    Venezuela. Russia is called a federation. Usually there is some
    overlapping or shared powers between national and state con-
    stitutions, legislatures, and court systems, and public agencies,
    taxing powers and regulatory functions, such as in interstate
    commerce and emergency response to natural or other disasters.

    In a unitary government system, most or all of the governing
    power resides in a centralized government. This contrasts with
    a federal system. In unitary systems the central government

    commonly delegates authority to subnational units and chan-
    nels policy decisions down to them for implementation.
    A majority of nation-states are unitary systems. They vary greatly.
    The UK includes England, Scotland, Wales, and Northern
    Ireland, each with legislatures, but the Westminster Parliament
    in London maintains national powers. In health, each of the four
    member entities of the UK conducts a National Health Service
    with autonomy but common features. The national government
    may delegate certain powers to self-governing regions/local
    authorities, and there is a growing tendency to devolve various
    governmental functions such as health to regional authorities.
    More than 150 countries are unitary states, including France,
    Italy, Spain, China, and Japan.

    In both forms of government, local authorities are estab-
    lished under state law with governance by councils elected
    by the people, with taxing and regulatory powers within the
    state or provincial laws, with a high degree of autonomy but
    within state regulation, standards, and financial support. Local
    authorities have major responsibilities in public health such as
    in sanitation, licensing, and regulation of businesses and zon-
    ing, as well as many other areas, including social welfare.

    BOX 15.10 Legal Structure of Federal and Unitary Countries

    efforts are being made to update and reform laws in the pub-
    lic health sector. In 1988, the Institute of Medicine (IOM) in
    the USA (the Future of Public Health) called for codifica-
    tion of public health law as essential for the public good,
    while questioning the soundness of certain US public health
    laws. More recently, the Model State Emergency Health
    Powers Act in the USA, the Quarantine Act in Canada, and
    the revised International Health Regulations (2007) have
    sought to update century-old legislation. The revised inter-
    national regulations provide for a global approach to con-
    trol the spread of epidemics and public health emergencies
    while minimizing disruption to international activities such
    as travel, trade, and economics.

    A combination of the regulatory, persuasive, and fund-
    ing approaches is widely used in public health in control of
    communicable and non-communicable diseases, in improv-
    ing standards of facilities, and in providing health services.
    The regulatory, enforcement, policing, and punitive func-
    tions of public health are important in health promotion and
    assurance of health care. The taxing power of government is
    essential for public health to ensure that adequate facilities

    and access to care are available to all members of the com-
    munity, especially those in financial need and thus at greater
    risk for disease.

    Medical officers of health and their staff have legal
    authority to issue formal orders for health protection of
    the public. Situations which require court proceedings are
    referred to the justice system. Situations that may require
    enforcement by court proceedings are referred to the justice
    system. Laws may be enacted to fund public health activi-
    ties, whether provided by public health authorities or by
    acting through official or non-official agencies or providers.
    Public health authorities, namely medical officers of health,
    have the legislative power to issue orders to individuals or
    businesses where there is a threat to the health of the public
    such as food establishments. Administrative resources are
    needed to enforce laws, such as through the FDA and the
    Environmental Protection Agency, which come under the
    aegis of the Department of Health and Human Services.
    Other departments such as Agriculture, Education, or inter-
    departmental agencies (e.g., Homeland Security), also are
    key to public health activities, such as in disaster situations.

    Other intergovernmental activities may require special leg-
    islation to empower, finance, and promote their cooperation,
    such as in the case of establishing an authority to manage
    long-term efforts to clean up a contaminated river or basin,
    which involves the cooperation and coordination of many
    local authorities.

    Health protection of individuals and communities may
    require legal action to detain a person in order to prevent
    the spread of a reportable communicable disease, to protect
    a mentally ill patient, or to restrain a violent person. Such
    powers should be used as a last resort if voluntary compli-
    ance and education fail, and where the danger to the commu-
    nity or the individual is sufficient to convince a court of the
    public need to override the personal liberty of an individual.
    An example is a 2007 case of a person with MDR-TB who
    was taken into custody on arrival for compulsory treatment
    after traveling across the Atlantic Ocean on a commercial
    airline, against the specific instructions of his physician, thus
    endangering fellow passengers. Outbreaks of measles in the
    UK (2006–2007) and in Israel via imported cases among
    ultraorthodox Jews or conservative protestant groups in the
    Netherlands, with transmission among religious people who
    tend not to immunize their children, led to pressure by health
    authorities to immunize those placed at risk by such contacts
    at weddings or other large public events.

    However, these measures are currently used less than
    voluntary isolation or quarantine and placarding homes for
    reportable infectious diseases such as measles. Powers are
    essential in extreme cases where refusal to comply with
    public health measures endangers others. Such powers
    should have been used more vigorously in the early years
    of the AIDS epidemic at a time when individual rights took
    precedence over protection of the population, including
    vulnerable high-risk groups. The severe acute respiratory
    syndrome (SARS) epidemic of 2003 led to sequestering
    hospital staff in Toronto, Canada, for lengthy periods to
    prevent spread of the disease, and subsequent influenza
    pandemic threats have raised questions as to whether hos-
    pital personnel should be required to be immunized to pro-
    tect patients and their families from onward transmission
    of dangerous infections.

    Recent cases in the USA, the UK, and Norway dem-
    onstrate the responsibility of governments to protect the
    public from incidents of violence by dangerous, mentally
    disturbed individuals who carry out mass killings. In Nor-
    way, 69 people, mostly teenagers, were killed by a radical
    ideologue while many others sustained serious injuries; and
    in the USA, Islamic terrorists at the Boston Marathon killed
    three and seriously injured more than 200 others; a 20-year
    old fatally shot his mother then killed 20 children and six
    adult staff members at Sandy Hook elementary school in
    Newtown, Connecticut, before killing himself; and an army
    psychiatrist who had become an increasingly devout and

    The New Public Health

    radicalized Muslim psychiatrist shot and killed 13 people
    and injured more than 30 others in a Texan army base.
    Background checks and other restrictions on gun sales are
    an important public health and political issue, especially in
    the USA. The wide availability of guns, including military-
    style assault weapons, presents a serious danger for impul-
    sive or planned mass killings.

    Public health has generally evolved with greater reli-
    ance on health promotion through voluntary cooperation of
    a patient or community than on compulsion. Enabling leg-
    islation may permit a local authority to fluoridate its water
    supply, but the enactment of local legislation and funding to
    implement it may also require a public referendum. In some
    states in the USA and in Israel, fluoridation of community
    water supplies is mandatory, which is also part of the health
    promotion approach to public health.

    Appropriation of public funds to promote public health is
    through approval by the legislature for a specified program.
    Provision of public funds may take the form of categorical
    grants for specified services, such as immunization, prenatal
    care, school health, or specific disease management such as
    TB control, cancer control, or AIDS education. Programs may
    be designed to promote certain types and quality of services,
    such as the Hill–Burton Act, which provided federal grants
    for hospital construction in the 1950s to 1970s, conditioning
    these grants on certain requirements concerning hospital licen-
    sure and hospital planning. Such legislation has a “carrot and
    stick” effect of attracting lower levels of government to seek
    such funding but also requiring them to accept the conditions
    and regulations that accompany the grants. The Canadian fed-
    eral government’s cost sharing of provincial health (hospital
    and medical) insurance programs is based on federal criteria
    requiring public administration, portability between provinces,
    accessibility without payment, comprehensiveness, and ban-
    ning extra billing by physicians (see Chapter 13).

    Public funds are also appropriated in the context of
    legislated programs in which people are entitled to the ser-
    vices defined in the appropriation legislation, such as in the
    amendments to the Social Security Act providing Medicare
    and Medicaid programs, or national health insurance legis-
    lation in many countries. These and their regulations spell
    out categories and specified entitlement benefits.

    Legislation and court decisions to protect the rights of
    the individual are part of public health. Public health law
    is meant to protect individuals and communities from
    potential abuse, of both individual and community human
    rights, as in the US Bill of Rights. Enforcement of public
    health law may infringe on individual rights by enforcing
    sanitation, food and drug safety, and supervision of res-
    taurants and catering firms. Laws may allow restriction of
    civil rights, such as rarely used mandatory treatment of a
    person with a dangerous contagious disease or mental ill-
    ness. Freedom of religion may come into conflict with other

    Chapter 15 Health Technology, Quality, Law, and Ethics

    laws in public health where restrictive practices may deny
    the use of publicly supported health facilities, as when a
    religiously affiliated hospital may refuse an abortion proce-
    dure in a case of rape. Religious practices or other personal
    beliefs may endanger others in the community, such as in
    the refusal to immunize children so that an imported infec-
    tious disease may spread among non-immunized people
    and even affect those who are immunized, as occurs with
    imported measles cases even when domestic transmission
    of the disease has previously been eradicated. General legis-
    lative provisions applied to public health forbid misleading
    or unethical advertising. Legislative provisions may also
    ban advertising for products, such as tobacco, which are
    legal but may be harmful to health. These laws affect public
    health but are provisions in other statutes such as the regu-
    lation of business enterprises. Legislation may also make
    smoking in public places illegal, with fines for offenders
    and operators of places such as public bars.

    Since the 1973 US Supreme Court decision of Roe v.
    Wade, the law has allowed women to seek safe and legal
    abortion. This remains a highly controversial political issue
    in the USA and several other countries. The potential con-
    flict between community and individual interests and rights
    is part of the dynamics of public health law and public health
    practice. The issues involved are complex and highly politi-
    cized, and often involve ethical distinctions where “the great-
    est good for the greatest number” may limit the legitimate
    rights of individuals and vice versa. The PPACA in 2010 is a
    fundamental legislative initiative, upheld by the US Supreme
    Court to become the law of the land. It will bring millions of
    Americans into regulated health insurance with many protec-
    tive elements to prevent abuse by private insurance company
    through arbitrary exclusions or limitations.

    The legal aspects of public health are vital to its opera-
    tion and are increasingly complicated by ethical issues, and
    by public and political debate. Health protective legislation
    and regulation for sanitation of food, water, and air are fun-
    damental to public health, as is the control of drugs, cosmet-
    ics, vaccines, and biologicals, the manufacture of devices,
    and the licensing of health personnel and facilities. Limi-
    tations of legal suits (torts) against manufacturers of vac-
    cines proved to be a successful measure in the USA with
    the introduction of the National Vaccine Injury Compensa-
    tion Program (NVICP) in 1988. This is funded by a modest
    surcharge tax collected from vaccine manufacturers. It pro-
    tects both public and private interests while providing a fair
    compensation system to ensure patients’ rights but without
    jeopardizing immunization to prevent widespread disease,
    and also protects manufacturers from litigation with high
    legal costs and excessive compensation awards by the jury
    system. Promoting healthy behavior through the prudent
    use of the legal system of regulation and taxation is increas-
    ingly utilized to protect the health of the population. This is

    803

    widely applied in promoting road safety, in tobacco control
    measures regarding banning of advertising, high taxes on
    alcohol, and banning smoking in public places including
    restaurants and bars.

    Environmental Health

    There is growing concern by the public and by governments
    over climate change, global warming, air and water pollu-
    tion, and other noxious and harmful industrial and com-
    mercial processes. Environmental laws affecting the public
    health include legislation on clean air, clean water, toxic
    substances, solid waste control, and other noxious sub-
    stances. Non-compliance with the legislative provisions can
    result in prosecution in the civil or criminal courts or both.

    Infringement of public health laws and regulations may
    lead to criminal action as an increasingly common method
    of sanction. While such violations may not be seen as “truly”
    criminal and may be treated in the courts as misdemeanors,
    they can lead to fines or even jail. Such cases are increas-
    ingly being addressed seriously in the judicial system.

    The CDC, in 1999, defined 10 great achievements
    of public health of the twentieth century. These achieve-
    ments are identified as control of infectious disease, motor
    vehicle safety, fluoridation of drinking water, recognition
    of tobacco use as a health hazard, immunization, decline
    in deaths from coronary heart disease and stroke, safer
    and healthier foods, healthier mothers and babies, family
    planning, and safer workplaces (Goodman et al., 2006).
    Of the 10 great achievements in the twenty-first century
    (2001–2010) identified by CDC, seven of the 15 leading
    causes of death (largely NCDs) resulted in a decline in the
    age-adjusted death rate in the USA from 881.9 per 100,000
    population in 1999 to 741.0 in 2009. This decline was a
    result of a combination of supportive laws and legal tools
    at the local, state, and federal levels. In other industrial-
    ized countries similar legislation has led to equal or greater
    achievements in public health over the past century.

    Public Health Law Reform

    Public health law is scattered through many legislative stat-
    utes and administrative documents which developed his-
    torically. Efforts to codify public health law may contribute
    to greater understanding and enforceability of the many
    separate pieces of legislation (Box 15.10). Such reform
    will enhance understanding in the legislative, judicial, and
    administrative branches of government as well as in busi-
    ness, non-governmental organizations, and the community.
    Box 15.11 suggests topics for model public health consoli-
    dation or compendia for states. The principles of this formu-
    lation may also apply to other countries at the national and
    state or provincial levels.

    804

    ETHICAL ISSUES IN PUBLIC HEALTH

    The field of public health includes a wide range of activities
    and professional disciplines, ranging from health promo-
    tion to disease protection, epidemiology to environmental
    health, and financing to supervision or provision of clinical
    care. Each of these disciplines works within systems that
    face ethical dilemmas, and public health workers’ under-
    standing and motivation within the ethical guidelines of
    their professions and roles are important in their training
    and practice conduct. Ethical frameworks have evolved in
    part as the result of bitter experience with ethical failures
    which were later recognized and affect public health stan-
    dards of practice for future generations (Box 15.12).

    Ethics in health are based on the fundamental religious
    and humanistic values and concepts of a society. If the prin-
    ciple of saving a life is valued above all other considerations
    (i.e., Sanctity of Life or Pikuah Nefesh) (see Chapter 1),
    then all measures available are to be used, irrespective of
    the condition of the patient or the cost. If sickness and death
    are seen as acts of God, possibly as punishment for sin, then
    prevention and treatment may be considered to be interfer-
    ing with the divine will, and the ethical obligation may be
    limited to relief of suffering. Humanism balances these two
    ethical imperatives: saving of life and relief of suffering.
    Materialistic political philosophies may view health care as
    primarily a function to preserve health for economic pros-
    perity and social well-being. Secular humanism adopted
    many of the religious precepts of the worth and rights of the
    individual and these have become part of the standards of
    law and ethics in modern secular societies.

    The role of society in protecting the health of the popula-
    tion grew during the nineteenth century with the sanitation

    (OSTLTS). PHLP develops law-related tools and provides
    legal technical assistance to public health practitioners and

    jurisdictions.

    The PHLP works with state/territorial health departments
    and other partners to:
    l identify public health law priorities
    l research laws that impact the public’s health
    l analyze public health legal preparedness
    l conduct comparative analyses across jurisdictions;

    prepare guidance, articles, reports, and toolkits; and
    develop and disseminate public health law curricula.

    The New Public Health

    movement, while medical care became an effective part of
    public health during the twentieth century. The astonishing
    successes of public health during the past century increased
    life expectancy in the high-income countries by some 30
    years, mostly through improved living conditions and
    health protection, as well as societal and medical advances
    to make care available to all. In the 1970s the Lalonde con-
    cept that individual behavior was one of the key determi-
    nants of health (see Chapter 2) placed much of the onus
    of illness and its prevention on the individual, but fostered
    health promotion as an essential component of public health
    theory and practice. All these points of view are involved
    in the ethical issues of the New Public Health (Box 15.13).

    Resources for health care are limited even in indus-
    trialized countries, so that priority setting and judicious
    allocation of scarce resources are always issues. Money
    spent on new technology with only marginal medical
    advantages is often at the expense of well-tried and proven
    lower cost techniques to prevent or treat disease. The
    potential benefits gained by the patient from more and
    more interventions are sometimes very limited in terms
    of length or quality of life. These are difficult issues when
    the physician’s commitment to do all to preserve the life
    of the patient conflicts with the patient’s concept of qual-
    ity of life and his or her right to decline or terminate heroic
    measures of intervention. Many health systems use clini-
    cal guidelines that are mandatory for a health facility or a
    doctor in the clinic. Preparation for surgery requires a sig-
    nature from the patient to consent to the procedure being
    carried out, careful preoperative procedures to ensure that
    the correct organ is addressed, antiseptic preparation of
    the site, and checking that all instruments are accounted

    for. The checklist approach is well established for care
    in many settings and protects the patient from neglect or
    faulty follow-up, such as in the management of hyperten-
    sion and diabetes.

    The suffering that a terminally ill patient may endure
    during radical treatment, which may prolong life by only
    hours or days, clashes with the physician’s ethical obli-
    gation to do no harm to the patient. The ethical value
    of sustaining the life of a terminally ill patient suffering
    extensively is an increasing medical dilemma. The issue is
    even more complex when economic values are included in
    the equation. There are potential conflicts among the eco-
    nomic issues, the role of the physician in preserving life,
    the physician’s obligation to do no harm, the felt needs
    of the patient and his or her family, and the needs of the
    community as a whole. The complex issues involved in
    the “right to die” and end-of-life care raise many ethical
    and legal questions for the patient, the family, society, and
    caregivers.

    The state represents organized society and has, among
    its responsibilities, a duty to promote healthful conditions
    and to provide access to health care and public health

    BOX 15.13 Study and Practice of Public Health Ethics

    Ethics is a branch of philosophy that deals with distinctions
    between right and wrong, with the moral consequences of
    human actions. The ethical principles that arise in epidemio-
    logical practice and research include:
    l informed consent
    l confidentiality
    l respect for human rights
    l scientific integrity.

    “As a field of study, public health ethics seeks to understand
    and clarify principles and values which guide public health
    actions. Principles and values provide a framework for decision
    making and a means of justifying decisions. Because public
    health actions are often undertaken by governments and are
    directed at the population level, the principles and values
    which guide public health can differ from those which guide
    actions in biology and clinical medicine (bioethics and medical
    ethics) which are more patient or individual-centered.

    As a field of practice, public health ethics is the application
    of relevant principles and values to public health decision mak-
    ing. Public health ethics inquiry carries out three core functions:

    (1) identifying and clarifying the ethical dilemma posed,
    (2) analyzing it in terms of alternative courses of action and their

    consequences, and
    (3) resolving the dilemma by deciding which course of action

    best incorporates and balances the guiding principles and
    values.” (CDC, 2001)

    services. The conflict between individual rights and com-
    munity needs is a continuous issue in public health. Appli-
    cation of accepted public health measures for the benefit of
    some people in society may require applying an interven-
    tion to everyone in a community or a nation. The major-
    ity thus are subject to a public health activity to protect a
    minority, without designating which individual’s life may
    be saved. Furthermore, a society may in special cases need
    to restrict individual liberties to achieve the goal of reducing
    disease or injury in the population. Raising taxes on alco-
    hol and tobacco products, mandatory speed limits, driving
    regulations, and seat belt usage laws are examples of pub-
    lic health interventions that interfere with individual liberty
    but protect individuals, and thereby the community at large,
    from potential harm.

    Many public health measures originally criticized as
    interventions in private rights are generally accepted as
    essential for health protection and promotion to reduce
    the risk of disease in the population. Chlorination of com-
    munity water supplies is a well-established, effective, and
    safe intervention to protect the public health. Fluoridation
    of drinking water to prevent tooth decay in children means
    that other people are also drinking the same fluoridated
    water, which is of less direct benefit to them. Fortification
    of foods with vitamins and minerals is also a cost-effective
    community health measure with advocates and opponents.
    The addition of folic acid to food as the most effective way
    to prevent neural tube defects in newborns is an intervention
    mandated by the US FDA since 1998.

    Confidentiality to assure the right of the individual to
    privacy involves ethical issues in the use of health infor-
    mation systems. Birth, death, reportable conditions (not
    all reportable diseases are infectious), and hospitalization
    data are basic tools of epidemiology and health manage-
    ment. The use of detailed individual data is needed for
    case-finding and follow-up activities which are vital to
    good epidemiological management of diseases, includ-
    ing STIs. However, caution is needed in data use to avoid
    individual identification that could be used punitively,
    for example, in denial of access to health insurance for
    smokers, alcoholics, or AIDS patients because health
    damage may be attributable to a self-inflicted risk factor.
    Increasingly, however, reporting is also mandatory for
    physical or sexual abuse and criminally linked injuries
    as essential for the protection of individuals at risk or the
    general public from serious harm.

    Individual and Community Rights

    The protection of the individual’s rights to privacy, and free-
    dom from arbitrary and harmful medical treatments, proce-
    dures, or experiments, may come up against the rights of the
    community to protect itself against harmful health issues.
    This conflict comes into much of what is done in public

    health practice, which has both an enforcement basis in law
    and practice and a humanitarian and protective aspect based
    on education, persuasion, and incentives. Society permits
    its governments to act for the common good, but sets limits
    that are protected by the courts and administrative appeal
    mechanisms.

    Society has the right to legislate the side of the road
    on which one is permitted to drive, the speed permitted,
    the wearing of seat belts, and the non-use of alcohol or
    drugs before driving or cell phones while driving. Offend-
    ers may be punished by significant fines or jail and are
    subject to strong educational efforts to persuade them to
    comply. Similarly, the community must ensure sanitary
    conditions and prevent hazards or nuisances from bother-
    ing neighbors or the public. Society must act to protect the
    environment against unlawful contamination or poisoning
    of food, drugs, the atmosphere, the water supply, or the
    ground.

    Enforcement is thus a legitimate and necessary activ-
    ity of the public health network to protect the community
    from harm and danger to health. Table 15.6 shows topics
    where individual rights and responsibilities predominate,
    and a second set of rights that are the prerogative of the
    community to protect its citizens against public health haz-
    ards. Sometimes the issues overlap and sometimes come to
    political, advocacy, or legal action, so that court decisions
    are needed to adjudicate precedents for the future.

    The AIDS epidemic in the 1980s and 1990s raised a
    host of public health, ethical, and issues. Management of
    the AIDS epidemic is in some respects in conflict with the
    long-established role of society in contacting and quarantin-
    ing people suffering from transmissible diseases. It is not
    acceptable or feasible in modern society to isolate HIV car-
    riers. But failure or delay of public health authorities even
    in the late 1980s to close public bathhouses in New York
    and other cities in the USA, where exposure to multiple
    same-sex partners promoted transmission of the infection,
    could be interpreted as negligence. During the 1980s, the
    gay community in the USA centered its concern that HIV
    testing would be used in a discriminatory manner. AIDS was
    initially addressed as a civil liberties issue and not as a pub-
    lic health problem. Screening, reporting, and case contact
    follow-up were seen as an invasion of privacy and proved
    counterproductive by increasing resistance to and avoidance
    of testing. Protection of privacy and an educational approach
    were adopted as most feasible and acceptable. International
    opinion and national court decisions have emphasized the
    right to privacy with decriminalization of non disclosure of
    HIV status to sex partners (UNAIDS 2013).

    The AIDS epidemic and public anxiety about contract-
    ing AIDS through casual contact reinforced the need for
    public education on safe sex. This has been raised as an
    ethical issue because such education may be construed as
    condoning teenage and extramarital relations. The issue of

    The New Public Health

    HIV screening of pregnant women in general or in high-risk
    groups took on a new significance with the findings that
    treatment of the pregnant woman reduces the risk of HIV
    infection of the newborn, and that breastfeeding may be
    contraindicated. This issue is arising anew in the context of
    using the HPV vaccine for preteen girls to prevent the sexu-
    ally transmitted infection, which is also controversial, and in
    the USA this vaccination will be mandatory for school entry.

    A pre-eminent ethical issue in public health is that of
    assuring universal access to services, and/or the provision
    of services according to need. An important ethical, politi-
    cal, and social issue in the USA in the twenty-first century
    is how to achieve universal access to health care. The soli-
    darity principle of socially shared responsibility for fund-
    ing universal access to health care is based on equitable
    prepayment for health care for all by nationally regulated
    mechanisms through place of work or general revenues of
    government. A society may see universal access to health
    care as a positive value, and at the same time utilize incen-
    tives to promote the use of services of benefit to the indi-
    vidual, such as hospital care, immunization, and screening
    programs. Some services may be arbitrarily excluded from
    health insurance, such as dental care, although this is to the
    detriment of children and a financial hardship for many.
    Strategies for program inclusion are often based on his-
    torical precedent rather than cost-effectiveness or evidence.
    While efforts are being made to include more children in the
    program, the Medicaid system in the USA defines eligibil-
    ity at income levels of 185 percent of the poverty line, thus
    excluding a high percentage of the working poor. Health
    is also a political issue in countries with universal health
    systems where funding may be inadequate or patient dis-
    satisfaction common.

    Choices in health policy are often between one “good”
    and another. Limitations in resources may make this issue
    even more difficult in the future, with aging populations,
    increasing population prevalence of physical disabilities,
    and rapid increases in technology and its associated costs.
    For example, the UK’s NHS at one point refused to provide
    dialysis to people over the age of 65. When computed tomog-
    raphy was first introduced, Medicare in the USA refused to
    insure this service as an untested medical technique. Owing
    to a lack of facility resources such as incubators and poor
    prospects for the survivors, the Soviet health system con-
    sidered newborns as living only if they weighed over 1000 g
    and survived for more than 7 days. Those under 1000 g, who
    would be considered living by other international definitions,
    would be placed in a freezer to die. At the opposite extreme,
    many western medical centers use extreme and costly mea-
    sures to prolong life in terminally ill patients, preserving life
    temporarily but often with much suffering for the person and
    at great expense to the public system of financing health care.

    In many countries, such as those in the former Soviet
    system of health care, spending for hospital services, in

    some cases grossly in excess of need, is accompanied by
    a lack of adequate funds for primary care or adding new
    vaccines to the immunization program for children. The
    majority of Americans have health insurance which increas-
    ingly includes preventive care services, but a substantial

    percentage lack such coverage which limits their access to
    routine preventive care. The Affordable Care Act brings an
    improvement in coverage and inclusion of preventive care
    with incentives (see Chapters 10 and 13). In many coun-
    tries, including in Europe, delay in updating immunization

    808

    programs may be due to a lack of funding or to delays
    in professional or governmental acceptance of “new”
    vaccines.

    The closure or amalgamation of hospitals involves dif-
    ficult decisions and is a source of friction between central
    health authorities, the medical professions, and local com-
    munities. Health reforms in many industrialized countries,
    such as reducing hospital bed supplies and managed care
    systems promoting cost containment and reallocation of
    resources, raise ethical and political issues often based on
    vested interests such as private insurance systems, hospi-
    tals, and private medical practitioners.

    Where there is a high level of cumulative evidence from
    the professional literature and from public health practice
    in “leading countries” with a strong scientific base and case
    for action on a public health issue, when does it become bad
    practice or even unethical public health practice to ignore and
    fail to implement such an intervention? Such ethical failures
    occur frequently and widely. For example, is it “unethical”
    not to fortify grain products with folic acid, and salt with
    iodine? Should there be a recommended European immu-
    nization program; should milk be fortified with vitamin D;
    should vitamin and mineral supplements be given to women
    and children; should all newborns be given intramuscular
    vitamin K routinely? Other examples include the issues of
    fluoridation of water supplies and opposition to genetically
    modified crops or generic drugs in African countries. These
    issues are continuously debated and the responsibility of
    the trained public health professional is to review the inter-
    national literature on a topic and formulate a position based
    on the cumulative weight of evidence. It is not possible to
    wait for indisputable evidence because in epidemiology and
    public health this rarely occurs. This is another reason for
    guidelines established by respected agencies and profes-
    sional bodies, which are free from financial obligations to
    vested interest groups, being essential for review of the evi-
    dence which continues to accumulate on many issues thought
    to have been resolved or which reappear repeatedly despite
    strong evidence of effectiveness and public health benefit.

    Tragic Deviations in Public Health Ethics

    In the nineteenth century the germ and miasma theories both
    produced enormous gains in public health. The biomedical
    paradigm addressed alleviation of disease risk or manifest
    disease; the health paradigm addressed the improvement of
    social and environmental conditions for reducing disease.
    During the early part of the twentieth century, a segment of
    the social hygiene movement promoted ideas of Social Dar-
    winism or racial improvement by sterilization of mentally
    ill, retarded, and other “undesirable” people.

    The dominant biomedical model of public health and
    medical professionals adopted policies of eugenics in
    Sweden, the USA, and Canada, leading to policies and

    The New Public Health

    programs to force the sterilization of mentally handi-
    capped or mentally ill patients. This distorted a socially
    oriented concept of public health. This euthenasia policy
    was adapted to a racially oriented policy with horrendous
    policies of mass murder in the name of racial purity as a
    public health policy in Nazi Germany with the near-total
    support and participation of a highly Nazified medical
    profession, and used in murder, by gassing or planned
    starvation, of half a million “undesirables” under the
    eugenics “T-4” program administered from Hitler’s head-
    quarters. Although this program was stopped after parental
    and Church protests in Germany, the methods used were
    adopted in newly occupied countries and for concentra-
    tion camps organized for the mass extermination of Jews,
    Gypsies, and others in the Holocaust.

    The eminent historian Sir Richard Evans (Regius Pro-
    fessor of History at Cambridge University), in his classic
    The Third Reich at War, wrote:

    “At the heart of German history in the war years lies the mass
    murder of millions of Jews in what the Nazis called ‘the final
    solution to the Jewish question in Europe’. This book provides a full
    narrative of the development and implementation of this policy of
    genocide, while also setting it in the broader context of Nazi racial
    policies toward the Slavs, and toward Gypsies, homosexuals, petty
    criminals and ‘asocials’. … For many years, and not merely since
    1933, the medical profession, particularly in the field of psychiatry,
    had been convinced that it was legitimate to identify a minority of
    handicapped as ‘a life unworthy of life’, and that it was necessary
    to remove them from the chain of heredity if all the many measures
    to improve the German race under the Third Reich were not to be
    frustrated. Virtually the entire medical profession has been actively
    involved in the sterilization programme, and from here it was but a
    short step in the minds of man to involuntary euthanasia.”

    The twentieth century was replete with mass murders,
    executions, and genocide, with nationalistic, ideological,
    and racist motives perpetrated by fascist, Stalinist, and
    radical xenophobic political or religious movements when
    gaining governmental power by election or by revolution,
    in some cases applying common public health terminol-
    ogy and concepts to uses of genocide and ethnic cleansing
    (Box 15.14).

    An outline of genocides of the past 100 years is seen
    in Box 15.15. These include the Turkish genocide of the
    Armenians in 1917 followed by horrific genocides in which
    many millions of people were killed, carried out under the
    communist regime of the Soviet USSR in the 1920s and
    subsequently, in the People’s Republic of China under
    Chairman Mao in the 1950s, and by the Khmer Rouge in
    Cambodia in the 1980s, and in the wars resulting from the
    breakup of the Yugoslav Republic in the 1990s.

    The human and national cost of genocide lasts for gen-
    erations. The hatred and fear may wane but the trauma goes
    deep. It lasts with the victims and their descendants, but

    Chapter 15 Health Technology, Quality, Law, and Ethics

    also with the perpetrating country and its culture. The Nazi
    Holocaust has had downstream effects in public health in
    the German-speaking countries which last to the present
    time, seven decades since the events took place. The long-
    term damage done to public health in Germany and Austria
    is described in Box 15.16.

    The Nuremberg Doctors’ Trial in 1946–47 convicted
    many leading Nazi physicians of crimes against humanity
    and resulted in severe punishments including hanging or
    long prison terms. This trial was a seminal event in estab-
    lishing the ethical standards required for medical research
    and human rights. However, many in the medical profession
    aligned with these horrors remained leading figures in the

    Health

    l Sanctity of human life.
    l Individual human rights – liberty, privacy, protection

    from harm.
    l Solidarity – sharing the burden of promoting and main-

    taining health.
    l Beneficence – reduce harm and burdens of disease and

    suffering.
    l Non-malfeasance – do no harm.
    l Proportionality – restriction on civil liberties must be

    legal, legitimate, necessary, and use the least restrictive
    means available.

    l Reciprocity principle – public responsibility to those who
    face disproportionate health and social burden.

    l Transparency principle – honest and truthfulness in the
    manner and context in which decisions are made must
    be clear and accountable.

    l Precautionary principle – decision makers have a general
    duty to take preventive action to avoid harm even before
    scientific certainty has been established.

    l Failure to act – public health officials and policy mak-
    ers have a duty to act and implement preventive health
    measures demonstrated to be effective, safe, and benefi-
    cial to population health. Failure to enforce public health
    regulations with resulting disease or deaths may consti-

    l Trust between the many stakeholders in health.
    l Reasonableness – decisions should be evidence based

    and revised based on new evidence.
    l Responsive to needs and challenges as they may be

    anticipated and appear with close monitoring of health
    status.

    German medical community, one even being elected to head
    the World Medical Association, then discussing the Helsinki
    Declaration of Ethics in Biomedical Research, before being
    forced to resign. The Nuremberg Trials and the subsequent
    Helsinki Declaration laid the fundamentals of biomedical
    ethics for the following generations, regulated by require-
    ments of ethical procedures and institutional research board
    approvals for funding, conducting, and publishing research
    involving human subjects (Table 15.7).

    The United Nations Convention on Prevention and Pun-
    ishment of the Crime of Genocide (UNGC) of 1948 defines
    acts committed with intent to destroy, in whole or in part,
    members of a national, ethnical, racial, or religious group
    as crimes against humanity. This convention specifies that
    incitement to genocide is itself a crime against humanity.
    Legal action should focus on state-sanctioned incitement
    as a recognized early warning sign. The UNGC defines
    genocidal acts to include the following as punishable under
    international law:

    l genocide
    l conspiracy to commit genocide
    l direct and public incitement to commit genocide
    l attempt to commit genocide
    l complicity in genocide.

    The reappearance of genocide in the late twentieth cen-
    tury in the Balkans and Rwanda, and in the twenty-first cen-
    tury by Sudanese in Darfur, highlights genocide as a public
    health concern and its prevention as a public health and
    international political responsibility. Incitement to genocide
    is a crime against humanity and was the basis for the trials
    and convictions of leaders of the Rwandan Tutsi tribe, as
    well as inciters to ethnic violence and the political leaders
    and perpetrators of mass murders in the former Yugoslav
    Republic. The threat and practice of genocide are still pres-
    ent, whether in the murderous raids of Sudanese Janjaweed
    militias in Darfur and South Sudan, the threats of genocide
    by Iran and associated terrorist organizations against Israel
    and Jews in general, or the killing of Christians in northern
    Nigeria and Egypt, of Muslims in Burma/Myanmar, and
    others. Incitement to genocide is now common as part of
    international discourse.

    Genocide represents the most extreme assault on the right
    to life and respect for life. In the twentieth century, an esti-
    mated 200 million people perished through genocide. Totali-
    tarian dictatorships, past wars, and ideologies of exclusiveness,
    ethnic purity, and religious fundamentalism increase the risks
    for genocide. Perpetrators use dehumanizing, demonizing,
    and delegitimizing hate language to desensitize or intimidate
    bystanders and to mobilize, order, and instruct followers.

    Genocide prevention requires international surveillance
    networks for monitoring and reporting incitement and hate
    language in the media, textbooks, places of worship, and the
    Internet, which should monitor and identify their sources

    The New Public Health810

    Eugenics was a movement within the “social hygiene” con-
    cept of the early part of the twentieth century. It was widely
    promoted to reduce births among mentally ill and handi-
    capped people in some states in the USA and was upheld
    in decisions of the Supreme Court. It was also practiced
    in Canada and Sweden. This idea was promoted by Hitler
    in Mein Kampf and adopted by the Nazi Party, which was
    legally elected to office in 1933 and began to implement it.
    Organized massacres of mentally ill and handicapped chil-
    dren and adults led to practices of organizing various modes
    of killing, including gas chambers, which were applied in
    concentration camps and in the Holocaust murder of 6 mil-
    lion Jews and millions of others.

    Genocide represents the most extreme assault right to life
    and respect for life. In the twentieth century, an estimated 200
    million have perished from genocide. Totalitarian dictator-
    ships, past war and defeat, ideologies of exclusiveness, ethnic
    purity, and religious fundamentalism increase risks for geno-
    cide. Perpetrators use dehumanizing, demonizing, and delegit-
    imizing hate language to desensitize or intimidate bystanders
    and to mobilize, order, and instruct followers.

    and map their distribution and spread. Dehumanization,
    demonization, delegitimization, disinformation, and denial
    are the danger signs of potential genocidal actions. Geno-
    cide results from human choice and bystander indifference.
    One lesson of the Holocaust is that silence in response to
    incitement to genocide makes one a complicit bystander.
    Public health professionals and institutions have a responsi-
    bility to speak out publicly on such dangerous early warn-
    ing signs (Richter E, personal communication, 2012).

    Human Experimentation

    Human experimentation has been a subject of great concern
    since the Nazi and Imperial Japanese armed forces’ experi-
    ments on prisoners and concentration camp victims during
    World War II. The Nuremberg Trials set forth standards of
    professional responsibility to comply with internationally
    accepted medical behavior (Table 15.7).

    The Helsinki Declaration was first adopted by the
    World Medical Assembly in 1964, and amended in 1975,
    1983, 1989, and 1996. It delineates standards of medical
    experimentation and requires informed consent from sub-
    jects of medical research. These standards have become an
    international norm for experiments, with national, state,
    and hospital Helsinki committees regulating research pro-
    posals within their jurisdiction. Funding agencies require
    standard approval by the appropriate Helsinki committee
    before considering any proposal, with informed consent on
    any research project.

    The Tuskegee experiment (Box 15.17) was a grave and
    tragic violation of medical ethics, but in the context of the
    1930s was consistent with widespread and institutionalized
    racism. It provides an important case study which has reper-
    cussions until the present time in suspicion of public health
    endeavors, particularly among the African American com-
    munity in the USA.

    811Chapter 15 Health Technology, Quality, Law, and Ethics

    In the German context the social–ecological health paradigm
    can be traced back to the late eighteenth and early nineteenth
    centuries when the country was a loose alliance of kingdoms
    or princedoms lagging behind the economic, cultural, and
    political developments in England and France. Ensuring popu-
    lation health was seen as the obligation of the state, while the
    family was responsible for caring for the health and well-being
    of its members. Organized health care and health maintenance
    was seen in the framework of Medizinische Polizey, as a model
    of the health systems. Leading scholars in law and medicine
    shared a normative perspective of promoting a healthy life-
    style (known as dietetics), and provision of shelter, food, and
    spiritual aid in asylums for the sick and disabled, or in private
    homes the for wealthy.

    In the second half of the nineteenth century evidence from
    medical statistics and overwhelming practical experience indi-
    cated that widespread poverty was the critical factor explain-
    ing high rates of typhus or cholera epidemics in lower social
    classes among children and industrial workers. A social health
    movement fought for healthier living and working conditions,
    education, and democracy. The movement’s prominent lead-
    ers were Salomon Neumann, a physician pioneer in medical
    statistics, and Rudolf Virchow, the renowned pathologist and
    outspoken political activist.

    Between 1890 and 1930 the conceptual framework of pub-
    lic health was defined as “social hygiene” or “health science”,
    an interdisciplinary field to conduct scientific research, aca-
    demic teaching, and community-based activities aiming at the
    promotion of individual and collective health and the preven-
    tion of disease. In the 1920s the field was highly developed and
    pioneering the modern academic public health.

    Social hygiene was a general framework open to different
    definitions. A group of academic teachers and publishing scien-
    tists sharing the social–ecological paradigm, among them a high
    proportion of German Jews, wanted to continue the social reform
    strategy and to strengthen local communities to take an active role
    in the formulation and implementation of health policies.

    Public health activists sharing the biotechnological disease
    paradigm favored a more focused approach aiming at the con-
    trol of disease through medical care. Although there was no

    supportive evidence, in the late nineteenth century a racial
    eugenic movement emerged widely in Europe and the USA.
    A conceptual model derived from the disease paradigm postu-
    lated racial factors to explain disease. A healthy population was
    assumed to be “free” of “racially contaminated” individuals and
    inferior groups. Health-related public policy was supposed to
    eliminate racially “unclean” members, e.g., by forced steriliza-
    tion or murder. This was a central theme in Hitler’s Mein Kampf
    and was enacted as basic policy by the Nazi Party in Germany
    as a fundamental ideological basis of racial theory and public
    health.

    When the Nazis were legally elected in Germany in 1933,
    and later seized power in Austria, this policy provided fertile
    ground to open the door to euthanasia, leading to mass mur-
    der. This was implemented in the well-organized, medically
    directed execution of mentally and physically handicapped
    Germans and others in psychiatric facilities. This provided a
    working model for the industrialized murder of 6 million Jews
    in the Holocaust and millions of gypsies, homosexuals, com-
    munists, and others.

    It took only 10 years to eradicate a 200-year tradition of
    German socially oriented public health grounded largely in the
    political philosophy of human rights and social justice. Most
    of those advocates were exiled or murdered. Many of the aca-
    demic medical leaders after World War II remained in key posi-
    tions in the German public sector for decades.

    In contrast to many other countries, the two wealthy
    German-speaking countries, with over 90 million people,
    have few academic public health resources. In there is only
    one German School of Public Health, and a small number of
    institutes, far fewer in Austria than in Germany. More than half
    a century has passed since the Nazi period and the populations
    of these two countries are slow to build a new socially oriented
    public health system.

    BOX 15.16 The Rise, Fall, and Slow Recovery of German Public Health

    Ethics in Public Health Research

    The border between practice and research is not always
    easy to define in public health, which has as one of its
    major tasks the surveillance of population health. This
    surveillance is mostly anonymous but relies on individu-
    ally identifiable data needed for reportable and infec-
    tious disease control as well as for causes of death, birth
    defects, mass screening programs, and other special dis-
    ease registries. It may also be necessary to monitor the
    effects of chronic disease, for example, to ascertain repeat
    hospitalizations of patients with congestive heart failure
    to assess the long-term effects of treatment, and the effects

    of strengthening ambulatory and outreach services to sus-
    tain chronic patients at a safe and functional level in their
    own homes.

    Hospitalizations, immunizations, and preventive care
    practices (e.g., Pap smears, mammography, and colonosco-
    pies) are all part of the New Public Health. Impact assessment
    of preventive programs may require special surveys and are
    important to assess smoking and nutritional status and other
    measures of health status and risk factors. Every effort must be
    made to preserve the anonymity and privacy of the individual
    but in some cases, where the disease is contagious, case contact
    is crucial. This can entail identifying people who attended an

    Human Rights, and the Declaration of Helsinki

    1946–47

    The voluntary consent of a human subject is absolutely essential, with the exercise of free power of
    choice without force, fraud, deceit, duress, or coercion

    Experiments should be such as to bear fruitful results, based on prior experimentation and the natural
    history of the problem under study. They should avoid unnecessary physical and mental suffering

    The degree of risk should not exceed the humanitarian importance of the experiment

    Persons conducting experiments are responsible for adequate preparations and resources for even the
    remote possibility of death or injury resulting from the experiment

    The human subject should be able to end his participation at any time

    The scientist in charge is responsible to terminate the experiment if continuation is likely to result in
    injury, disability, or death

    Universal Declaration
    of Human Rights, 1948

    Biomedical research should be carried out by scientifically qualified persons, only on topics where
    potential benefits outweigh the risks, with careful assessment of risks, where the privacy and integrity
    of the individual is protected, and where the hazards are predictable. Publication must preserve the
    accuracy of research findings

    Each human subject in an experiment should be adequately informed of the aims, methods,
    anticipated benefits, and hazards of the study. Informed consent should be obtained, and a
    statement of compliance with this code

    Clinical research should allow the doctor to use new diagnostic or therapeutic measures if they
    offer benefit as compared to current methods

    In any study, the patient and the control group should be assured of the best available methods.
    Refusal to participate should never interfere with the doctor–patient relationship. The well-being
    of the subject takes precedence over the interests of science or society

    The general distinction between research and practice
    has to do with the intent of the activity. Clinical research uses
    experimental methods to establish the efficacy and safety of
    new interventions or unproved interventions; many drugs
    and procedures in common use have never been subjected

    to randomized controlled trials. In practice, many methods
    are devised that are held to be effective and safe by expert
    opinion and documented as such. Researchers comparing

    and withholding them from the control group. The scientific
    justification of an experiment must be made explicit and
    justifiable. Clinical equivalence is a necessary condition
    of all clinical and public health research and provision of
    standard of care treatment to control groups is a minimal
    requirement for most research ethics boards. Determination
    of the standard, and whether it should be place, time, and
    community specific, is an area of ongoing controversy.

    In 1996 a US Public Health Service study, supported by
    the NIH and WHO, compared a short course of zidovudine
    (AZT) to a placebo given late in pregnancy to HIV-positive
    women in Thailand, measuring the rate of HIV infection
    among the newborns. The experiment was terminated when
    a protest editorial appeared in a prominent medical journal.
    This study confirmed previous findings that AZT given dur-
    ing late pregnancy and labor reduced maternal–fetal HIV
    transmission by half. When a study shows clearly positive
    results, it should be discontinued and reported so that the
    findings can be applied generally. The findings indicated
    that AZT should be used in developing countries, and the

    BOX 15.17 The Tuskegee Experiment

    The Tuskegee experiment was carried out by the US Public
    Health Service between 1932 and 1972. It was meant to fol-
    low the natural course of syphilis in 399 already infected
    African American men in Alabama and 201 uninfected men.
    The men were not told that they were being used as research
    subjects. The experiment had been intended to show the
    need for additional services for those infected with syphilis.
    However, when penicillin became available, the research-
    ers did not inform or offer the men treatment, even those
    who were eligible when drafted into the army in 1942. The
    experiment was stopped in 1972 as “ethically unjustified”
    when the media exposed it to public scrutiny.

    The case is considered unethical research practice
    because, even at the time it was conducted, it did not pro-
    vide the patients with available care and their well-being
    was put aside in the interest of the descriptive study. A similar
    experiment was conducted by the US Public Health Service
    in cooperation with the Guatamala Ministry of Health dur-
    ing the 1960s, in which syphilis was actually given to sol-
    diers, prisoners, and others by sexual contact with prostitutes
    known to have the disease, but the study was terminated
    when it was discovered by a public health historian and
    reached public attention in the USA.

    In 1997, President Bill Clinton apologized to the survi-
    vors and families of the men involved in the experiment on
    behalf of the US government. The Tuskegee experiment is
    the source of lingering widespread suspicion in the African
    American community to the present time.

    manufacturers agreed to make it available at reduced costs.
    The result has been a major success in helping with more
    recent medications to reduce maternal–fetal transmission in
    many places in Africa with help from GAVI, and a slowing
    of the spread of HIV/AIDS-related deaths.

    Public health may face the challenge of pandemic influ-
    enza, such as avian flu, with decisions regarding the allocation
    of vaccines, treatment of massive numbers of patients arriv-
    ing at hospitals in acute respiratory distress with very limited
    resources available, coping with sick or absent staff, and many
    other issues requiring not only individual life and death situ-
    ations, but mortality en masse. The ethical questions will be
    replaced by struggles to cope with such situations. Preparation
    for such potential catastrophic events will be a challenge to
    public health organizations and the health system in general.

    An outstanding case of a breach of ethics in public health
    research occurred with the “Wakefield effect”, as described
    in Chapter 4 and Box 15.18.

    Ethics in Patient Care

    Ethical issues between the individual patient and health
    care provider are important in the New Public Health. A
    doctor is expected to use diligence, care, knowledge, skill,
    discretion, and caution in keeping with practice standards
    accepted at the time by responsible medical opinion and
    to maintain the basic medical imperative to do no harm
    to the patient. Patients have the right to know their condi-
    tion, available alternatives for treatment, and the risks and
    benefits involved. They also have a right to seek alterna-
    tive medical opinions, but this right is not unlimited, as any
    insurance plan or health service may place restrictions on
    payment for further opinions and consultation without the
    agreement of a primary care provider.

    Health care has a responsibility beyond that of the pay-
    ment of health service bills and individual care by a physi-
    cian, in institutions, or through services in the community
    or the home. The contract for service is becoming less
    between an individual physician and his or her patient, and
    more among a health system, its staff, and the client. This
    places a new onus on the physician to ensure that patients
    receive the care they require. Conversely, the US provider
    often faces the dilemma of knowing that a patient may not
    access needed services because of a lack of adequate health
    insurance.

    Sanctity of Life Versus Euthanasia

    The imperative to save a life is an important ethical and prac-
    tical issue in health care. Advocates of physician-assisted
    suicide (euthanasia) argue for the right of the patient to die
    with dignity when the illness is terminal and the individual
    is suffering excessively. This is not a medical decision alone,
    and is an agonizing issue for society to address. The Nazi
    euthanasia program and its human experiments provided

    The New Public Health814

    In 1998, The Lancet, published an article by a number of well-
    known researchers headed by Dr Andrew Wakefield. The article
    reported on 12 cases of autistic children and alleged to show a
    connection to immunization with the MMR (measles–mumps–
    rubella) vaccine.

    The immediate effect of this “revelation” was widespread
    alarm over the MMR vaccine and a fall off in immuniza-
    tion coverage by measles-containing vaccines in the UK
    and elsewhere with many mothers refusing to have their
    child vaccinated due to a “risk of autism”. As a result,
    measles epidemics occurred in the UK and in many other
    countries, with measles again becoming endemic in many
    parts of Europe, especially England and France.

    After a long series of investigative journalism in the British
    press, the article came under scientific scrutiny and withdrawal
    of many of the coauthors but a consistent insistence by the lead
    author of its authenticity.

    Investigation by British medical authorities later found
    Dr Wakefield guilty of medical negligence and the UK
    General Medical Council withdrew his license to practice
    medicine. The coauthors were found to have been credulous
    and insufficiently vigilant in agreeing to coauthorship of the
    paper. In 2000, 12 years after the original publication, The
    Lancet formally withdrew the article.

    The effect of this fraudulent scientific publication was a
    serious loss of credibility of immunization in general and
    especially regarding the MMR vaccine, one of the greatest life
    savers in public health technology.

    The return of measles in Europe to large scale epidemics
    with frequent international transmission furthered the loss of

    confidence of mothers in immunizations and public health.
    Measles-containing vaccines were particularly strongly
    affected owing to the publicity given to the Wakefield case.
    The journal editors could be seen as irresponsible for failing
    to ensure the scientific integrity of lead authors and coauthors,
    and the journal for failing to retract a fraudulent article sooner
    than 12 years after the first publication.

    In other public health issues, single publications of findings
    of small sample and poorly assessed studies published in haste
    without adequate inquisitive review occur with great frequency.
    The electronic media often include unscientific opinion blogs
    which appear larger than life which provoke great anxiety over
    accepted and successful public health interventions such as flu-
    oridation or folic acid fortification of flour, with unsubstantiated
    claims that they cause cancer, asthma, and other ill-effects.

    The interface between ethics, law, and science in pub-
    lic health requires continuous sensitivity to the downstream
    effects of “shouting fire in the theater”.

    BOX 15.18 The Wakefield Effect

    the direst of warnings to societies of what may follow when
    the principle of the sanctity of the individual human life is
    breached. The issue, however, returned to the public agenda
    in the 1980s and 1990s as advances in medical science have
    allowed the prolongation of human life beyond all hope of
    recovery. Legislation in the Netherlands, the USA (“assisted
    suicide” in the states of Washington, Oregon, and Montana),
    and northern Australia has legally sanctioned euthanasia
    with various safeguards in a variety of circumstances, such
    as long-term comas or terminal illnesses.

    Doctors, patients, relatives, and health care organiza-
    tions need clear guidelines, orientation, procedures, legal
    protection, and limitations where failure to take utmost
    steps to “save” the patient by intubation, resuscitation, or
    transplantation may cause legal jeopardy. Even though a
    distinction can be drawn theoretically between permitting
    and facilitating death, in practice, doctors in intensive care
    units face such decisions regularly where the line is often
    blurred. Hospital doctors routinely go to extreme mea-
    sures to prolong the life of hopeless cases. Such decisions
    should not be considered for economic reasons alone, but in

    practice the costs of care of the terminally ill will be a driv-
    ing force in debate of the issue. Living wills allow a patient
    to refuse heroic measures such as resuscitation, with “do
    not resuscitate” standing orders and assignment of power of
    attorney to family members to make such decisions. Fam-
    ily attitudes are important, but the social issue of redefining
    the right of a patient to opt for legal termination of life by
    medical means will be an increasingly important issue in
    the twenty-first century.

    The Imperative to Act or Not Act in Public
    Health

    As in other spheres of medicine and health, in public health
    the decision whether to intervene on an issue is based on
    identification and interpretation of the problem, the poten-
    tial of the intervention to improve the situation, to do no
    harm, and to convince the public and political levels of the
    need for such intervention along with the resources to carry
    it out. This process requires patience and a longer time-
    frame than many other fields in health.

    Chapter 15 Health Technology, Quality, Law, and Ethics

    Some interpretations of ethics in health consider that the
    only purpose for which power can be rightfully exercised
    over any member of a democratic community, against his
    will, is to prevent harm to others. But this is not a dictum
    that is applied to public health, which is obliged to act to
    protect the public health in so many spheres such as food
    and drug safety and environmental health, on a spectrum
    that extends to banning smoking in public places, mandat-
    ing food fortification, and many other areas of civil society.

    Failure to act is an action, and when there is convincing
    evidence of a problem that can be alleviated or prevented
    entirely by an accepted and demonstrably successful inter-
    vention, then the onus is on the public health worker to
    advocate such action and to implement it as best as possible
    under the existing conditions. Failure to do so is a breach of
    “good standards of practice” and could be unethical. Iner-
    tia of the public health system in the face of evidence of a
    demonstrably effective modality such as adoption of state-
    of-the-art vaccines or fortification of flour with folic acid
    to prevent birth defects would come under this categoriza-
    tion and may even constitute neglect and unethical practice.
    This is not an easy categorization, because there is often
    disagreement and even opposition to public health interven-
    tions, as was the case with opposition to vaccination long
    after Jenner’s crucial discovery of this procedure in the late
    eighteenth century. It is also true today with opposition to
    many proven measures such as fluoridation or fortification
    of basic foods. Box 15.19 shows the ethical standards of the
    APHA in 2006.

    The use of ethical and high standards of practice in pub-
    lic health (Box 15.20) requires an ideological commitment
    to the advancement of health standards and use of best prac-
    tices of international standards to the maximum extent pos-
    sible under the local conditions in which the professional is
    working. This is not an easy commitment as there is often
    dispute and outright hostility to public health activities, in
    part because of ethical distortions of great magnitude in the
    past. But this is an optimistic field of activity because of the
    great achievements it has brought to humankind. Prepara-
    tion for disasters and unanticipated health emergencies in
    addition to addressing current issues is a vital part of the
    New Public Health and our ethical and professional com-
    mitments.

    SUMMARY

    In order to maintain and improve standards of care, health
    systems need quality assurance and technological assess-
    ment as part of their ongoing operation. Poor-quality care
    is costly in terms of iatrogenic diseases and prolonged or
    repeated hospitalization. If innovations such as endoscopic
    surgery are not introduced, then longer hospital stays are
    needed for the same operation, wasting the patient’s time
    and productivity, while utilizing expensive health care

    815

    resources, and incurring the risks associated with more
    invasive surgery.

    Health care is provided by people, as well as by insti-
    tutions with a range of devices and equipment. The people
    providing care, more than the technological facilities, set the
    quality of care. Nevertheless, progress on the technological
    side of medical care is vital to the continuing development
    of the field. Modern medications, monitoring equipment,
    laboratory services, and imaging devices have made enor-
    mous contributions to advances in medical care. Appropriate

    to prevent adverse health outcomes.

    l Public health should achieve community health in a way
    that respects the rights of individuals in the community.

    l Public health policies, programs, and priorities should be
    developed and evaluated through processes that ensure

    l Public health should seek the information needed to
    implement effective policies and programs that protect
    and promote health.

    l Public health institutions should provide communities
    with the information they have that is needed for deci-
    sions on policies or programs and should obtain the

    the mandate given to them by the public.

    l Public health programs and policies should incorpo-
    rate a variety of approaches that anticipate and respect
    diverse values, beliefs, and cultures in the community.

    l Public health programs and policies should be imple-
    mented in a manner that most enhances the physical and
    social environment.

    l Public health institutions should protect the confidential-
    ity of information that can bring harm to an individual or
    community if made public. Exceptions must be justified
    on the basis of the likelihood of significant harm to the
    individual or others.

    l Public health institutions should ensure the professional
    competence of their employees.

    l Public health institutions and their employees should
    engage in collaborations and affiliations in ways that
    build the public’s trust and the institution’s effectiveness.

    The New Public Health816

    Publication in peer-reviewed journals is a key part of the
    advancement in science and a vital part of the development
    of the scientific basis for public health practice. The process of
    publication should promote rigorous standards of high quality
    ethical research and the wide dissemination of their findings.
    Codes of practice for editors and publishers of peer-reviewed
    journals have been developed by both the Committee on
    Publication Ethics (COPE) (Rees, 2011) and the World
    Association of World Editors (WAME).

    Editors are subject to competitive pressures, and the over-
    arching metric of success is seen to be the impact factor, a
    measure of the frequency with which the “average article”
    in a journal has been cited in a particular year or period.
    Relevant, rigorous research of better quality will tend to be
    cited more frequently, and thus editorial strategies that look
    for quality and relevance in the given field will increase the
    impact factor. However, there can also be potential distort-
    ing factors. Publishing a highly controversial paper can result
    in high citation levels. Publishing studies which demonstrate
    negative findings may be less likely to attract large numbers
    of citations.

    Key issues relate to conflicts of interest, and the potential for
    advertising and sponsorship to distort editorial decision mak-
    ing (Gray, 2012). A particular concern has been the pernicious
    influence of the tobacco industry in sponsoring, frequently
    covertly, research which has aimed to confuse or obfuscate key
    findings linking second hand exposure to tobacco to adverse
    impacts on health. Similar tactics are used in other areas where
    health and commercial interests collide. Clear statements of
    potential conflicts of interest are essential. Journal owners must
    not interfere in the evaluation, selection, or editing of individ-
    ual articles, either directly or by creating an environment in
    which editorial decisions are strongly influenced.

    Other challenging areas are plagiarism and research mis-
    conduct. The latter is extremely difficult both to detect and to
    deal with, and requires close working between institutions and
    editors who may suspect professional misconduct. In cases of
    fraud, the publishing journal should withdraw the article in a
    timely fashion (see Box 15.18: The Wakefield Effect).

    There has been a rapid rise in open access publishing, in
    part underpinned by an ethical belief that research is a public
    good, and an increasing number of influential research funders
    now require that there should be unrestricted access to the
    published output of research. In addition, several publishers
    make their journals free to those in selected low-income coun-
    tries, promoting dissemination to those who might not other-
    wise afford them.

    In summary, publication in peer-reviewed journals remains
    a key method for establishing and progressing the evidence
    base for public health practice. The consequences of poor
    or frankly fraudulent science can have a substantial adverse
    impact both on health and on the use of resources. Editors must
    adhere to high ethical and professional standards and remain
    vigilant to avoid allowing external drivers to distort their deci-
    sion-making processes. They must strive to maintain integrity
    and high scientific standards to advance the field of public
    health practice (Smith, 2007).

    BOX 15.20 The Ethics of Publication in Public Health

    technology is a critical issue for international health, since
    the most advanced technology may be completely inappro-
    priate in a setting that cannot afford to maintain it or lacks
    the trained personnel to operate it, or where it comes in
    place of more vital basic primary care services. Technology
    assessment needs to be seen in the context of the country and
    its resources for health care.

    Ethical issues in public health are no less demanding
    than those related to individual clinical care. The rights of
    the individual and those of the community are sometimes in
    conflict. Technology, quality, the law, and ethics are closely
    interrelated in public health. Well-informed and sensitive
    analysis of all aspects of their development is a part of the
    New Public Health. The balance between individual and
    community rights is very sensitive and must be kept under
    continuous surveillance.

    The New Public Health is replete with technological
    and ethical questions, especially in a time of cost restraint,
    increasing technological potential, the public expectation

    of universal access to health care, and the assumption that
    everyone will live a healthy and long life. Health status has
    always been linked with socioeconomic status and, despite
    enormous gains, this remains true even in the most egalitar-
    ian countries. Expansion of market mechanisms, such as
    controlling the supply of hospital beds, doctors, and access
    to referrals, competition and incentives/disincentives in
    payment systems for hospital and managed care systems,
    contribute to a need for dynamic health policy management
    capacity. The New Public Health assumes a social responsi-
    bility for health for all, using community and personal care
    modalities as effectively as possible to achieve that overall
    goal.

    KEY MESSAGES AND SUMMARY

    viii

    • A system of case-based groups (CBG) is a classifi ca on system that groups pa ent cases,
    including services received, into standardized groups according to several variables – most
    commonly diagnosis, treatment or procedure received, and pa ent characteris cs.

    • The introduc on of a CBG system is a long-term endeavour which needs con nuous
    investment and upda ng. The introduc on of a CBG system should have clear objec ves
    and should be accompanied by a clear implementa on plan that includes intermediate
    steps, responsibili es for the actors and involved, and melines.

    • In most countries the CBG system is used to collect informa on on hospital ac vity, to inform
    budget formula on/nego a on and o en, to serve as a payment system. Its largest impact
    is that it clearly shows for which services and to which providers funds are allocated.

    • The design and meframe for the introduc on of the CBG system have to fi t with the country
    context and the capaci es of purchasers and providers. Available capaci es for coding, claim
    processing, fi nancial management, management of purchaser-provider rela ons (including
    contrac ng) and informa on management should be assessed.

    • Providers require a degree of autonomy in the management of their funding in order to
    respond to the incen ves set by a CBG payment system (e.g. by changing mix of staff or
    other inputs).

    • The introduc on of a new payment method is not only a technical process. The poli cal
    economy around the introduc on of the system and the expected shi ing of resources will
    create supporters and opponents. The Ministry of Health and purchasers should consult
    relevant stakeholders, especially providers, during the development of the system.

    • If it is possible to launch payment system using an imported diagnosis-related groups (DRG)
    system within a few years, this is only feasible with strong capaci es of purchasers and
    providers, and electronic medical records based on standardized coding systems already in
    place. In most countries, adapta ons to the health management informa on system, the
    purchasing modali es and adjustments to the imported DRG system will take several years.

    • The development of a classifi ca on algorithm is the technically most complex task. Most
    countries will start with an imported DRG grouping algorithm, or at least get some inspira on
    from exis ng grouping algorithm, that will be adjusted to the country context.

    • In other cases a gradual approach, star ng with a simple CBG system based on a simple
    classifi ca on algorithm which is then con nuously developed, will be more realis c. Such
    an approach can s ll achieve strategic purchasing objec ves while giving both fi nancial and
    informa on management systems me to mature.

    • Data quality is key for a DRG system but a simpler CBG system can incen vize and help
    improve data collec on. Weaknesses in data collec on or data quality should not prevent a
    country from introducing a CBG system.

    • A CBG system is a tool to contribute to the objec ves of universal health coverage (UHC).
    Incen ves set by the system should be carefully considered to ensure that integrated people-
    centred care, and not economic considera ons, remains the overall objec ve. Monitoring
    of impact on treatment quality is needed in addi on to claims monitoring. It is important to
    note that gaming and coding creep is going to happen.

    INTRODUCTION AND PURPOSE OF THIS GUIDE

    ixINTRODUCTION AND PURPOSE OF THIS GUIDE

    More and more low- and middle-income countries are seeking to strengthen strategic
    purchasing arrangements in the health sector by using evidence-based processes to defi ne
    which specifi c health services should be purchased from which providers, how the services
    should be paid for and at what rate they should be paid (1, 2). A purposively aligned mixed
    provider payment system is one of the core policy instruments leading to more strategic
    purchasing in order that diff erent payment methods will create a coherent set of incen ves to
    infl uence and guide provider behaviour towards health system objec ves (3). Related thereto,
    payments based on case-based groups (CBG) or, more specifi cally, diagnosis-related groups
    (DRG) have gained increased interest from policy-makers across the globe. This document
    focuses specifi cally on CBG and DRG. The diff erences between CBG and DRG are explained
    below. In general, this publica on uses CBG as the wider umbrella term for a case-based
    classifi ca on system and refers to DRG when these are meant explicitly.

    When considering the introduc on of a CBG system, many policy choices and technical
    ques ons arise. Policy-makers have to judge the pros and cons of a CBG system in rela on
    to their country context and the health system challenges they wish to address. They will
    have to explore whether, and if so how, to introduce a CBG system, and should assess
    which ins tu onal arrangements and resources are available and which would be required.
    Importantly, this guide on CBG does not suggest or imply that these payment methods are
    a magic bullet or the only op on to consider when seeking to improve the payment system.

    There is a large body of literature on CBG, and in par cular on DRG, but it focuses primarily
    on high-income countries. The purpose of this guide is to explore specifi cally the CBG-related
    policy ques ons and issues relevant to the context of low- and middle-income countries. This
    document seeks to provide specifi c guidance and evidence to policy-makers and prac oners
    on core ques ons regarding design and implementa on that they will be faced with when
    introducing a CBG system. The guide is wri en in a Ques on & Answer (Q&A) format. It
    provides literature references for further reading and for more technical details and presents
    various country cases to illustrate specifi c issues.

    The document consists of four parts:

    Part 1 outlines defi ni ons, terminology and the main conceptual aspects related to CBG and
    DRG.

    Part 2 covers the assessment phase and highlights ques ons and issues that policy-makers
    should consider before taking the decision to introduce a CBG system.

    Part 3 delves into the prepara on phase by exploring policy and design aspects once a country
    has decided to introduce a CBG system.

    Part 4 is concerned with the implementa on phase and discusses implementa on ques ons,
    requirements for system adjustments and the need for monitoring and revision in order to
    iden fy and address unintended impacts of a CBG system.

    Technical terms are included in a glossary at the end of the document for easy reference.

    A case-based groups (CBG) system is a
    pa ent classifi ca on system that groups
    pa ent cases, including services received,
    into standardized case groups according
    to diagnosis and treatment or procedure
    received. It combines a clinical logic with an
    economic logic. A CBG system can be used
    to collect more detailed and/or standardized
    informa on about the services provided to
    pa ents, as well as in addi on as a provider
    payment method (4, 5).

    CBG classifi ca on systems usually have the
    following features in common (5-7):

    • Each case group contains cases with similar
    pa erns of resource use (“resource-
    homogeneous”).

    • Cases within a group share common
    features from a clinical perspec ve
    (“clinically meaningful”).

    • Each case can be classifi ed into one group
    (i.e. the classifi ca on is exhaus ve).

    • The use of variables to defi ne a group and
    to assign a case is based on informa on
    collected rou nely in medical records.

    In its simplest version, there would be only
    one case group – i.e. each pa ent falls
    into the same group. If used for payment,
    providers would receive the same amount
    for every pa ent discharged. With one case
    group and one payment rate, the payment
    system would, however, not consider
    diff erences in severity and costs across
    cases (4) and would not create the desired
    incen ves intended by a CBG system.

    When a pa ent classifi ca on system is based
    on medical special es or the chapters of
    the Interna onal Classifi ca on of Diseases
    (ICD) with no other variables, it would
    usually consist of 25–27 groups. Addi onal
    classifi ca on factors to refl ect the main
    cost drivers – such as a whether surgery
    or medical imaging is provided, added to
    those chapters of the ICD for which they
    are relevant – will ensure that groups are
    economically more homogenous and lead
    to pa ent classifi ca on systems with around
    50 case groups in total.

    As more variables are added into the
    classifi ca on logic, the number of cases
    groups will increase. This will also depend
    on the informa on and level of granularity
    available in medical records which can be
    used for coding. However, the resul ng
    number of groups needs to be manageable.
    However, for case groups to remain
    economically homogenous, a meaningful
    average treatment cost has to be allocated
    to each case group. This requires a certain
    number of cases per group, a condi on which
    would not be fulfi lled by a classifi ca on
    system in which every diagnosis would be
    considered as a dis nct case group (5).

    A more complex and specifi c form of CBGs
    are diagnosis-related groups (DRGs) in that
    addi onal and more detailed informa on
    on mul ple variables such as pa ent
    characteris cs, procedures undertaken,
    severity of the case, primary and secondary
    diagnosis, comorbidi es and complica ons,
    and/or type of admission are used for the
    grouping.

    2 HEALTH FINANCING GUIDANCE NO. 10

    In general, a DRG (payment) system
    comprises:

    – a pa ent classifi ca on system based
    on the set of several variables to defi ne
    groups,

    – a classifi ca on algorithm, which is the set
    of instruc ons for assigning a par cular
    case to a specifi c group according to the
    pa ent classifi ca on logic, and

    – usually a specialized so ware – called
    “grouper so ware” – for the digi zed
    case assignment.

    Based on the number of variables used for
    classifying pa ent cases, the number of case
    groups range from several hundreds to over
    2000 cases (4, 5, 8).

    DRG systems vary primarily according to
    the classifi ca on variables they use and
    the grouping rules applied, such as which
    diagnoses are classifi ed into the same
    group or how the classifi ca on steps are
    sequenced (9-11). Sec on 3.2 outlines which
    classifi ca on variables are frequently used.
    The diff erent DRG systems are referred to
    as DRG variants or models and have been
    given names (e.g. “Australian DRG”). A DRG

    variant represents a specifi c classifi ca on
    system, including a related algorithm and,
    if applicable, a grouper so ware. Most DRG
    variants exist in several versions that refl ect
    the regular updates of the classifi ca on
    algorithm. As countries regularly update
    their DRG systems, the consecu ve versions
    of a country variant can diff er signifi cantly
    depending on the scope of the revision.
    Sec on 3.4 presents the main DRG variants
    in place around the globe.

    The dis nc on between CBG and DRG
    systems is not clear cut, rather exis ng
    systems show a range of diff erent levels of
    complexity. Figure 1 shows the con nuum
    ranging from a simpler CBG system to a
    DRG system. It stretches from a (theore cal)
    system with only one case to more complex
    systems with over 2000 case groups defi ned
    through several variables (e.g. major
    diagnosis, surgery provided or not, severity,
    medical procedures, pa ent characteris cs
    and comorbidi es). Such more complex
    systems are manageable only by using
    electronic pa ent records and grouping
    so ware. These more complex systems are
    referred to as DRG systems.

    A CBG system assigns a rela ve case-group
    weight to each case group. This case-group
    weight refl ects the resources needed to
    diagnose and treat a case in a respec ve
    case group compared to the average
    cost of diagnosing and trea ng across all
    cases. Alterna vely, as is the case in some
    countries, a direct monetary value is given
    to each case group.

    The base rate is the average rate paid per
    case. The payment for a case is the product
    (mul plica on) of the base rate and the
    respec ve rela ve case-group weight.
    The base rate is the same for all cases and
    usually links the CBG payments with the
    overall available budget for the providers
    and services paid by the CBG system (4).

    The case mix is the sum of the rela ve case-
    group weights of all cases treated in a health
    facility during a given period.

    The case mix index (CMI) is the case mix
    for a given health facility during a given
    period divided by the total number of cases
    (classifi ed under the CBG system) treated
    by this health facility during the given
    period. It thus is the weighted average of
    the case-group weights of all cases treated
    in that facility. The CMI enables ac vity and
    the level of its complexity to be compared
    across health facili es. It can also be used
    to determine global budget alloca ons to
    health facili es (4, 12).

    In general, the CMI of lower-level facili es
    is lower than that of higher-level facili es,
    such as ter ary care and university hospitals.
    University or ter ary hospitals providing a
    higher share of complex services would have
    a CMI well above 1 (12, 13).

    In a case-based payment system, providers
    are paid on the basis of case groups (“case-
    based groups”) with a fi xed fi nancial amount
    per case discharged. This means that
    payments for providers are linked to ac vity
    (4, 14).

    The payment for the cases is, in principle,
    determined by a formula consis ng of:

    – rela ve case-group weights which
    indicate the rela ve cost-intensity of
    cases of diff erent groups,

    mul plied by

    – a base rate,

    mul plied by

    – adjustment factors which allow one to
    take into considera on the diff erences
    in the economic or hospital context
    (e.g. remoteness, teaching facility)
    in which providers operate or the
    sociodemographic or socioeconomic
    profi les of the pa ents (6, 15).

    1.2. WHAT ARE CASE GROUP WEIGHTS, THE BASE RATE,
    CASE MIX AND CASE MIX INDEX?

    1.3. HOW IS THE PAYMENT DETERMINED IN A CASE-BASED
    PAYMENT SYSTEM?

    Annex 1 outlines country examples with various classifi ca on systems, showing how diff erent
    cases are allocated to groups and thus indica ng diff erent levels of complexity.

    Some countries started to set up their case-
    based payment systems without using case-
    group weights, base rates or adjustment
    factors. Instead, they allocated an amount
    to each defi ned case. This has been the case,

    for instance, in Ghana, Morocco and the
    Philippines in the beginning (16-18).

    determining a DRG-based payment rate.

    The ul mate objec ves of UHC encompass
    u liza on in line with need (i.e.
    equitable access), quality in health care
    and fair fi nancing, while intermediate
    UHC objec ves relate to effi ciency,
    equitable distribu on of resources, and
    transparency. However, many countries
    face challenges due to, inter alia, ineffi cient
    use of funds (e.g. over-provision, under-
    provision, inappropriate size of facili es or
    insuffi ciently priori zed health services),
    inadequate quality of service provision,
    and a lack of transparency.

    Each payment method, and the combined
    mix of payment methods, sets incen ves
    for providers and in turn have a posi ve
    or nega ve impact on these objec ves
    (19, 20). A summary of diff erent payment
    methods and their characteris cs is
    included in Annex 2. This sec on examines
    the incen ves that a CBG payment system
    creates and ways in which it can contribute
    to the fi nal and intermediate objec ves of
    UHC.

    In general, CBG payments set two main
    incen ves: 1) providers may reduce the
    inputs (and hence costs) per case treated,
    and 2) they may try to increase the number
    of cases, both of which helps them to
    increase their income.

    With regard to the fi rst incen ve, a CBG
    payment system can improve effi ciency
    in the use of funds by reducing, or even
    avoiding, overtreatment and unnecessary
    services while maintaining quality, since
    healthcare providers have an incen ve to
    reduce the amount of inputs per case. A
    certain degree of autonomy of providers
    will be needed to incen vize them to
    manage their resources more effi ciently
    and to allow them to reallocate savings.
    On the other hand, this incen ve makes
    providers reduce treatment inputs, thus
    poten ally also leading to under-provision
    per case or to reduced quality of care
    (skimping). Moreover, providers may
    engage in cream skimming of pa ents with
    less severe symptoms, refer complex cases,
    or discharges pa ents too early in order to
    reduce inputs needed for treatment and
    hence costs (4, 20, 21).

    With regard to the second incen ve above,
    CBG payments can induce providers to
    increase the number of treated cases (12,
    22), for example by readmi ng pa ents or
    unbundling cases into individual services
    to in order to claim for more cases.
    Nonetheless, an increase in case numbers
    can be desirable when the hospital
    u lisa on rates for certain services are
    very low or when there are wai ng lists.

    2.1. CAN A CBG PAYMENT SYSTEM CONTRIBUTE TO
    ACHIEVING UHC OBJECTIVES?

    6 HEALTH FINANCING GUIDANCE NO. 10

    Moreover, through upward adjustment
    of case-group weights for selected cases,
    resul ng in rela vely higher payment rates
    for such cases, a CBG payment system
    can be designed to incen vize providers
    to priori ze certain health services and
    to shi a en on to the needs of specifi c
    popula on groups or geographical areas.

    By paying for outputs and alloca ng funds
    to ac vi es, a CBG payment system may
    reduce the funds of providers whose
    ac vity is too low to be economically
    viable. As a result, the payment system
    can result in a restructuring of the provider
    sector as providers with insuffi cient ac vity
    may have to close down, merge with other
    providers, or adjust their service delivery
    structures (4).

    Furthermore, a CBG system collects
    standardized informa on on hospital ac vity
    which can improve transparency on the
    types and volume of health services – such as
    diagnoses, procedures, severity indicators
    and pa ent characteris cs – delivered by
    each hospital. When aggregated across
    all hospitals, a CBG system can provide
    data on the epidemiological profi le of a
    popula on, can indicate which popula on
    groups and health services are the focus
    of hospital ac vity and can show how the
    budget is distributed across hospitals (21,
    23). The informa on collected through a
    CBG system can also serve to measure and
    compare performance across providers (e.g.
    in rela on to cost of treatment or average
    length of stay). This informa on can be used
    strategically to encourage improvements
    in quality of care or to review pa ent care
    pathways systema cally (21, 24).

    In sum, it is important to note that a CBG
    system, whether for informa on collec on
    and monitoring and/or for payment, is
    not a magical solu on to health system
    performance challenges. A careful
    assessment is needed to determine whether
    the introduc on of a CBG system is most
    appropriate or whether another provider
    payment reform might be more suitable to
    address a country’s performance issues in a
    given context.

    However, when well designed and
    implemented, a CBG (payment) system
    can contribute to the UHC objec ves (2).
    Nevertheless, monitoring and control
    mechanisms are needed so as to avoid that
    the incen ves set by a CBG payment system
    lead to provider behaviour and hence
    consequences that are not conducive to
    UHC, i.e. increased overall expenditure,
    increased service provision beyond the
    desired level and reduced quality (4,
    20, 21). More informa on on how the
    incen ves set by a CBG payment system
    and its consequences can be addressed is
    provided in Sec on 4.3. Table 1 summaries
    the poten al eff ects of CBG introduc on
    on cost-containment, effi cient use of
    resources, be er informa on collec on
    and administra ve costs, depending on
    the payment system in place prior to CBG
    introduc on. Evidence suggests that a mix
    of provider payment methods is needed
    to balance mul ple policy objec ves (e.g.
    quality of services and cost containment
    (20).

    The introduc on of a CBG system is o en
    part of a larger health-fi nancing reform or
    a package of measures to make purchasing
    more strategic. Country experience shows
    that clear and realis c objec ves are needed
    for CBG introduc on, as well as a detailed
    implementa on plan with clear melines.
    Evidence also suggests that a health system
    that is fi nanced predominantly from
    public sources facilitates the launching of

    such payment reforms (4, 5) Moreover, a
    single-payer model or a harmonized and
    standardized CBG payment system among
    mul ple purchasers augments purchasing
    power and will allow for a stronger leverage
    of the CBG system in order to shape
    provider incen ves and behaviour (7).

    Beyond these conducive factors, there are
    cri cal ins tu onal requirements that need
    to be in place, as outlined below.

    A CBG system requires detailed pa ent-
    level informa on collected through an
    informa on management system as well as
    ins tu onal capacity to use such a system.
    At best, a rou ne data collec on system,
    including medical records, should exist; if
    not, it needs to be developed (see Sec on
    3.2 on what data need to be collected).

    In fact, collec ng more detailed and be er
    data on pa ent cases and the treatments
    provided, or the introduc on of pa ent
    records, can be one objec ve of introducing
    a CBG system. In this case, the CBG system
    and the envisaged, more comprehensive
    health informa on management system can
    be developed jointly, growing more complex
    over me and mutually suppor ng their
    further development (6, 14). Importantly,
    an informa on management system
    involves more than data collec on; it also
    encompasses data analysis, verifi ca on,
    valida on and audi ng (26). Data audi ng
    is cri cal because there are likely to be

    both inten onal and uninten onal coding
    mistakes in most CBG systems (27). The
    purchaser needs to be able to trust the
    quality of data coding for otherwise it may
    be reluctant to use the system for payment.

    A thorough assessment of the exis ng
    informa on management system will
    reveal the current set-up and func oning
    as well as poten al gaps. This is the basis
    on which to further develop and adapt the
    informa on management system to the
    data needs of a CBG system.

    Foremost, the health informa on
    management system needs to be based on
    standardized coding of pa ent cases (27,
    28). For example, for a CBG system relying
    on diagnosis as a criterion for grouping,
    the Interna onal Classifi ca on of Diseases
    (ICD) – and/or country-specifi c adapta ons
    of it – can serve to provide a standardized
    coding format.

    2.2. WHAT ARE THE CONDUCIVE FACTORS AND
    INSTITUTIONAL REQUIREMENTS FOR A CBG SYSTEM?

    An eff ec ve informa on management system for hospital data

    9ASSESSMENT PHASE

    Health staff – i.e. doctors and nurses –
    should have the capacity for rou ne coding
    of pa ent cases, including diagnoses and
    procedures. In many countries with a
    CBG system, providers therefore employ
    specifi c CBG or DRG coders. These staff are
    trained in this specifi c competence and are
    responsible for transla ng medical records
    into the coding format required by the
    CBG system (29). Moreover, the capacity
    of health facility managers needs to be in
    line with the (increased) level of autonomy
    they are granted, which should accompany
    the shi from input-based to output-based
    payment. Moreover, the administra ve
    staff need the capacity to collect, analyse
    and make decisions about cost informa on
    related to service delivery in order to
    allocate resources across input categories
    and medical departments (21).

    At the purchaser level, capaci es for claim
    management and verifi ca on are essen al
    in order to ensure that claims comply with
    relevant regula ons and that providers

    receive payments on me. A purchaser
    also needs the skills to design and adjust
    the incen ves of the CBG payment system
    in order to align provider behaviour with
    health-system objec ves. Together with the
    regulators, the purchaser also needs to be
    able to monitor any poten ally unintended
    consequences of CBG payments. In addi on,
    the classifi ca on and coding procedures
    need to be standardized, regulated and
    enforced. This should be accompanied
    by monitoring measures to encourage
    improvements in the quality of coding and
    regular updates. This is frequently under
    the responsibility of the Ministry of Health,
    which needs capacity to maintain the health
    informa on management system and to
    use data strategically. Ministries of health
    or purchasers have o en created new units
    with exper se in CBG coding, classifi ca on
    and cos ng (26, 27). Those units will play
    a role in con nuously upda ng the system,
    as noted under Sec on 4.5.

    When public funds are allocated to providers
    via a CBG payment system, it is important
    that public fi nancial management rules
    allow output-based payment methods to be
    used. If this is not the case, modifi ca ons in
    exis ng budget formula on and execu on
    rules may be needed (30). Providers also
    need suffi cient fi nancial and managerial
    autonomy and fl exibility in the use of funds

    to allow them to respond to incen ves
    set by the payment method. Provider
    autonomy should go along with strong
    accoun ng and audit systems to ensure
    accountability in the use of funds (4, 6).
    An account of the importance of provider
    autonomy in Mongolia’s introduc on of a
    CBG system is contained in Box 1.

    Box 1. The importance of provider autonomy to accompany the introduction of a
    CBG system in Mongolia

    Since it was put in place the Mongolian health insurance scheme has used a fl at case
    payment rate for all inpa ent cases diff eren ated by the levels of health facili es. In
    2006 CBG was introduced payments using 22 case groups and extended to 115 groups
    in 2010. Ini ally, this switch to more refi ned output-based payment method was not
    accompanied by any change in budge ng or in budget execu on rules. Both the Ministry
    of Finance and the Ministry of Health have supervised providers through 1) appointment
    of their execu ve managers; 2) annual budget cap based on historical line-item budget
    planning for a part of provider’s revenue; 3) quotas on hospital staff ; 4) line item-based
    budget execu on plans with limited fl exibility to shi funds across items; and 5) other
    bureaucra c procedures on residual claimant – i.e. responsibility for covering poten al
    losses and using poten al surpluses (31). Since providers lack managerial and fi nancial
    autonomy to use or reallocate effi ciency gains through CBG payments, there is no strong
    incen ve to reduce inputs per case.

    In 2013, Mongolia’s new Integrated Budget Law signifi cantly changed public fi nancial
    management regula ons. In par cular, the number of major line items in the budget
    used for planning and repor ng was reduced from 38 to 5. Providers were given more
    fl exibility to make realloca ons across budget line items and the maximum amounts that
    they can use fl exibly without seeking prior approval have been increased. Since 2016,
    hospital boards, which were set up in 2011, have had the authority to approve spending
    plans and to appoint the execu ve management of public hospitals. It is expected that
    these reforms in hospital autonomy, combined with gradual capacity-strengthening of
    hospital managers in developing, implemen ng and repor ng on output-based budgets,
    will create the space for the CBG payment system to set effi ciency incen ves and also
    lead to stronger buy-in by providers into the new payment system.

    The fi rst country to develop and introduce
    a DRG system was the United States of
    America, with the process taking more
    than 10 years before the system was ready
    to be used for payments. Therea er, and
    based on this experience, the rollout took
    5–10 years in several European countries.
    Importantly, ICD coding was already in
    place both in the USA and Europe. Figure
    3 gives an overview of how long it took to

    start using CBGs for payment in various
    countries (28). In most countries, a CBG
    system has been introduced in phases with
    gradual extensions, as further detailed
    in Sec on 4.2. Even under the most
    conducive condi ons, the introduc on
    is likely to take several years (5). Box 2
    describes the progressive development
    and implementa on of DRGs over several
    years in Chile.

    Moreover, a CBG classifi ca on system and
    related cost weights or payment rates need
    con nuous adjustments and updates to
    ensure that the grouping remains clinically
    meaningful and economically homogenous
    and that it refl ects new health technologies.
    The introduc on of a CBG system is not a
    one-off project (32). The issue of regular
    upda ng is further discussed in Sec on 4.5.

    The cost of the introduc on and design
    process of a CBG system depends on many
    factors and is diffi cult to es mate. No such
    informa on was found in publicly available
    sources. However, the cost implica ons of
    the following aspects need to be considered,
    apart from resources needed for the policy
    dialogue and high-level planning:

    When buying (impor ng) a DRG system:

    – costs of buying a classifi ca on system,
    including the grouping algorithm and
    the grouping so ware in the case of a
    DRG system;

    – cost for adjus ng the imported DRG
    system to the country context;

    – ini al and ongoing licensing cost, where
    required.

    When developing a CBG system:

    – costs of developing an own classifi ca on
    system and the corresponding grouping
    algorithm and grouping so ware.

    In addi on, there are:

    – costs for introducing/adjus ng the
    facili es’ informa on management
    systems;

    – costs for introducing/adjus ng the
    informa on management systems of
    purchasers;

    – costs for data collec on and cos ng
    studies to inform payment rates and
    rela ve cost weights under the CBG
    system;

    – costs for training staff of providers and
    purchasers;

    – costs of fi nancial incen ves that may be
    needed to obtain ini al support from
    providers or to encourage complete
    repor ng (especially when the CBG
    system is not used for payment);

    – costs for communica on and advocacy
    to providers and the wider public.

    Box 2. DRGs in Chile: a case of progressive implementation

    In Chile a fi rst DRG pilot, focusing on informa on collec on and analysis of case mix,
    started in 2002 in four major hospitals with technical support from the Catholic University
    of Chile. The pilot highlighted the relevance of having a strong hospital informa on
    management system, the need to agree on and collect the necessary minimum set of
    data and the importance of designa ng and training coding teams for data entry.

    From 2007 onwards, the Ministry of Health and FONASA (the na onal health fund,
    opera ng as a health insurance type purchaser) were evalua ng the possibility to use
    DRGs as hospital payment method. Star ng in 2010, the Interna onal Refi ned (IR)-
    DRG variant was gradually expanded to 25 public hospitals for informa on collec on.
    Hospitals developed their coding capacity, implemented DRG so ware and applied a
    standardized system for collec on of cost informa on. Case weights and calcula on
    of the base rate have been developed and con nuously revised. In 2017, accoun ng
    systems in public hospitals had matured suffi ciently to provide necessary informa on for
    a detailed cos ng study to re-evaluate both rela ve case group weights and the base
    rate.

    Star ng in 2015, FONASA uses fl exible contrac ng mechanisms to pilot DRG payments
    for private providers. FONASA decided to buy bed days from the private sector for a set
    of pathologies for which there are long wai ng lists in the public sector. It expressed
    those pathologies in DRGs. As cost structures diff er between public and private providers,
    there are diff erences in DRG rates between the public hospitals, with their rates being
    based on cos ng studies, and the private sector, with rates being based on a tender
    process. However, funding channelled through DRG to private providers accounts for
    less than 1% of FONASA’s total budget.

    The implementa on of DRG payments in Chile has been slow and the DRG system is s ll
    mainly used for informa on collec on. FONASA has announced its plan to extend DRG
    payments in 2020 to public hospitals.

    A range of diff erent stakeholders will be
    involved and/or infl uencing the design and
    implementa on of a CBG system. First, the
    parliament and the whole of government
    will be involved if changes to legisla on are
    needed. The Ministry of Finance defi nes
    public fi nancial management rules, which
    also apply to the CBG payment system,
    and has an interest in protec ng fi nancial
    sustainability. Interest groups such as
    provider associa ons, pa ent associa ons
    or medical associa ons are o en consulted
    formally on health policies but may also
    try to lobby informally to ensure that their
    interests are refl ected (33, 34). The technical
    nature of the introduc on of a CBG system
    usually limits ac ve involvement in the
    development process to the Ministry of
    Health, the purchasing agencies, provider
    associa ons and medical associa ons.

    The Ministry of Health and/or the
    purchasing agency are usually the drivers
    for the development of a CBG system.
    The Ministry of Health, as steward of the
    health system, is interested in improving
    data collec on and in ensuring that CBG
    payments set the right incen ves for
    providers to align their behaviour with
    health-sector objec ves and UHC goals.
    For the purchasing agency, a CBG payment
    system serves to increase effi ciency in the
    use of funds, to contain costs and to gather
    be er informa on about the services and
    providers on which the funds are spent
    (35). Addi onally, high-level leadership by
    the Ministry of Health will be required in
    order to overcome poten al opposi on
    and to support the development of a CBG
    system that is acceptable to all stakeholders

    (35). Country experience shows that a
    specifi c unit, or at least a designated team,
    should be set up to take charge of CBG
    development. Over me a mandated unit
    that is able to maintain the system will be
    equally important (28).

    The introduc on of a CBG payment system
    implies (re-)alloca on of funds and/or
    changes to how decisions on fund alloca on
    are taken. Some facili es may receive more
    funds than before while others may receive
    less. As a result, some providers may be
    cri cal of the introduc on of a CBG payment
    system. However, diff erent providers will
    have diff erent interests. Hospitals with a
    complex case mix may be more suppor ve
    of a CBG system than rural hospitals
    providing a low volume of services. It is
    important that providers are consulted
    and involved during the design process and
    that the classifi ca on logic is transparent
    (29, 35). To encourage provider buy-in, the
    purchaser and the Ministry of Health should
    ensure that provider perspec ves are taken
    into account, provider concerns about
    poten al losses of revenue are discussed
    and transi onal measures are considered
    (see more details in Sec on 4.2 on phasing
    in the CBG payment system). Provider trust
    in the payment system and a feeling that it
    leads to a transparent and fair distribu on
    of resources are equally important (14).

    External experts, agencies providing
    technical assistance and private sector
    developers of CBG systems or so ware
    might also contribute to the development
    process and it is important that their eff orts
    are aligned with the government agenda.

    2.4. WHICH STAKEHOLDERS ARE LIKELY TO INFLUENCE THE
    DESIGN AND IMPLEMENTATION OF THE CBG SYSTEM
    AND HOW SHOULD THE DIFFERENT STAKEHOLDERS BE
    INVOLVED?

    14 HEALTH FINANCING GUIDANCE NO. 10

    CBG systems are based on the classifi ca on
    of health services into clinically and
    economically homogenous groups. For that
    ma er, most CBG systems ini ally apply
    to acute inpa ent care in hospitals. Acute
    inpa ent care services are rela vely easier
    to classify as cases can be defi ned as all
    diagnoses, tests and treatments provided
    between admission and discharge. Also,
    inpa ent services usually account for a
    large share of health sector spending (6,
    36).

    In contrast, it is diffi cult to apply a CBG
    system to health services for which
    diagnosis or other grouping criteria are
    not good predictors of treatment costs.
    This is the case, for instance, for long-term
    psychiatric or rehabilita on care or when
    the number of cases is too small to calculate
    a meaningful average cost for cases within
    a specifi c case group (e.g. for organ
    transplants). Likewise, for intensive care

    or cases requiring expensive therapeu cs
    and medicines, it is not the diagnosis
    that drives the cost but the intensive care
    stay or the price of medicines. Most CBG
    systems therefore do not apply to these
    types of services or they provide addi onal
    payments for such outliers, as noted under
    Sec on 4.3 (22, 37).

    Several high-income countries have
    extended CBG payments to some outpa ent
    care services. However, outpa ent health
    care services are in most cases paid through
    fee-for-service, line-item budgets, global
    budgets or capita on payments. This is
    because cost diff erences between diff erent
    primary health care and/or outpa ent
    services are less stark, thus less in line with
    the underlying logic of CBGs. Using CBGs
    for high-volume and low-cost services
    could also imply dispropor onately high
    administra ve costs (20, 38).

    FINA
    L DR

    AFT
    A CBG payment system that aims at cost
    control or restructuring of the hospital
    sector should include those health facili es
    that consume a signifi cant share of health
    service cost. Inpa ent care, and especially
    surgical cases, usually consume a large

    part of the budget. Primary care facili es
    provide health services that are less
    resource-intense. As a result, most CBG
    payment systems apply to secondary and
    ter ary care facili es (4, 20).

    3. PREPARATION AND DESIGN PHASE

    AND PROVIDERS SHOULD BE INCLUDED IN THE CBG
    PAYMENTS?

    Which types of health services should be part of the CBG payments?

    Which types of facili es should be included in the CBG payment?

    15PREPARATION AND DESIGN PHASE

    In a number of low- and middle-income
    countries, public fi nancing for health
    services can be spent only on government
    health-care providers. However, the
    transparent alloca on of CBG funds to
    providers could create the necessary trust
    and accountability to make it possible to
    pay private providers using public funds.
    Addi onally, the inclusion of private
    providers in a CBG payment system will allow
    for the systema c collec on of informa on
    on their services. It may be necessary
    to adjust CBG payment rates for private
    providers, especially when government
    providers con nue to receive some budget
    alloca ons (e.g. for health worker salaries)
    along with the CBG payments (21, 29). In
    addi on, through selec ve contrac ng,
    purchasers may choose to pay only selected
    public or private providers through CBG
    payments.

    The types of facili es in a hospital market
    can be very heterogeneous, ranging from
    local hospitals in remote areas to rather
    urban-based secondary and ter ary
    hospitals in the public and private sector
    that provide high-technology services.
    Decisions on the design of the CBG system,
    including which providers to cover, should
    be examined cri cally with regard to the
    poten al impact on, and alignment with,
    overall priori es in equitable access to
    services and fi nancial coverage.

    aspects to further consider when deciding

    The star ng point for building a CBG
    classifi ca on system, par cularly when
    it is to be used for payment, are the key
    determinants of resource consump on –
    generally diagnoses and procedures – as
    classifi ca on variables (15). These and
    other variables that are commonly used
    for classifi ca on are explained below. The
    actual order of sequence depends on the
    CBG system and its specifi c classifi ca on
    algorithm.

    Diagnosis: Most CBG systems start by
    grouping cases on the basis of principal
    diagnosis into major diagnos c categories
    that correspond to organ system or
    cause/e ology and that are generally
    associated with medical special es. In
    general, classifi ca on systems dis nguish
    fewer than 30 major diagnos c categories
    (5). Major diagnos c categories mostly
    follow ICD chapters. Annex 3 provides two
    examples of DRG variants with their major
    diagnos c categories.

    Coding of principal diagnoses (as well as
    of secondary diagnoses, see below) can
    be based on ICD-10, an earlier ICD version,
    or ICD-11 (which was adopted by the
    World Health Assembly in May 2019) or a
    country-specifi c adapta on. The diagnosis
    will provide the most accurate informa on
    on a popula on’s disease burden. However,
    diagnoses are not always good predictors of
    cost because resource needs for treatment
    tend to depend primarily on the procedures
    used rather than on the diagnoses (5).

    Some CBG systems start their classifi ca on
    process by iden fying cases that are both
    highly specialized and high-cost and assign
    them to a so-called “pre-MDC group”
    (where “MDC” refers to “major diagnos c
    categories” into which the other cases will
    then be categorized). The pre-MDC cases
    are o en paid by other payment methods
    since it is diffi cult to classify them in
    economically homogeneous groups (5).

    Secondary diagnoses: Secondary diagnoses
    refl ect comorbidi es and complica ons
    that are used in an addi onal grouping
    step because they also have a signifi cant
    eff ect on treatment cost. In addi on, some
    classifi ca on systems dis nguish between
    levels of severity within a diagnosis. DRG
    systems include comorbidi es for coding,
    but this adds complexity and requires
    providers to have stronger coding capaci es
    and purchasers to be able to check coding
    accuracy (5, 14). Several high-income
    countries have also added the func onal
    status of pa ents as a classifi ca on variable1
    (39).

    Procedures: Most CBG systems also
    include procedure codes because several
    procedure or treatment op ons may exist
    for a diagnosis. Procedure and treatment
    op ons are equally decisive for treatment
    costs. The principal diagnosis combined
    with a procedure can be a good start for
    the development of a simple CBG system
    which can then be gradually developed
    further. The simplest and most common

    3.2. WHICH VARIABLES CAN BE USED FOR CLASSIFICATION
    AND WHAT ARE THE IMPLICATIONS?

    1 For coding of func onal status the Interna onal Classifi ca on of Func oning, Disability and Health (ICF) provides a
    standardized coding format. The WHO Disability Assessment Schedule 2.0 (WHO-DAS 2.0) provides an ICF-based, generic
    instrument for func onal status assessment. The WHO-DAS 2.0 has also been incorporated into the ICD-11 sec on on
    func oning.

    diff eren a on is between medical and
    surgical cases (5). Current procedure coding
    is o en country-specifi c (5). The Beta-2
    dra of the Interna onal Classifi ca on of
    Health Interven ons (ICHI) was launched
    by WHO in 2019. It will provide guidance
    and orienta on for coding interven ons in
    an interna onally comparable manner (40).

    Pa ent characteris cs: Pa ent
    characteris cs can serve as addi onal
    classifi ca on variables. Pa ent age is the
    most important pa ent characteris c to
    aff ect treatment cost. Case-group weights
    or payment rates can be diff eren ated for
    children and adults undergoing procedures
    for which age has diff erent cost implica ons.
    Sex as a pa ent characteris c is primarily
    used as a quality check to ensure that
    sex-specifi c diagnoses and procedures
    are reimbursed only for pa ents of the
    respec ve sex. Moreover, with regard
    to promo ng equitable access to health
    services, cost weights or payment rates
    could be diff eren ated for pa ents from
    poor or marginalized popula on groups (5).

    Administra ve variables related to
    admission and discharge: Cases can
    further be diff eren ated by admission
    type, such as inpa ent versus day case/
    outpa ent or elec ve versus non-elec ve
    surgery. Another op on is to diff eren ate
    by discharge type, such as discharge,
    referral or death (5).

    Variables related to resource consump on:
    The case classifi ca on may consider
    variables that indicate a higher resource
    consump on within a case. Examples
    include length of stay, use of mechanical
    ven la on, or a stay in a specialist
    department (e.g. intensive care unit,
    psychiatric ward) or use of high cost drugs
    (5).

    Case classifi ca on in a DRG system is
    generally based on the following fi ve main
    steps (5):

    1. Before the classifi ca on begins, the
    data are checked to exclude cases with
    incorrect or missing informa on.

    2. Very high-cost and highly specialized
    cases (e.g. organ transplants) are
    iden fi ed and put into a special “pre-
    MDC” category.

    3. Cases are allocated to mutually exclusive
    MDCs according to the principal
    diagnosis. A few systems use other
    variables such as age (e.g. to assign cases
    to a neonatal major diagnos c category).

    4. The grouping algorithm classifi es
    pa ents into a “surgical” or “medical”
    par on. Some systems include
    addi onal variables with other relevant
    non-surgical procedures, such as medical
    imaging.

    5. All DRG systems check for further
    characteris cs of the case, such
    as complexity of the principal and
    some mes secondary diagnoses, type
    of procedures, combina ons of both,
    and some mes age, length of stay or
    treatment se ng, or type of discharge.
    This serves to assign the pa ent to the
    fi nal case group.

    However, sequencing of variables varies
    across DRG variants. Annex 1 provides
    simplifi ed overviews of diff erent
    classifi ca on systems. When selec ng
    the variables for the case classifi ca on
    system, it is important to consider what
    poten al incen ves these variables create
    for providers. If a certain diagnosis can
    be treated by more than one procedure,
    providers will have an incen ve to use
    the procedure with the highest return for
    the hospital. A descrip on of how Ghana
    developed its pa ent classifi ca on system
    is contained in Box 3. Box 4 illuminates the
    process of iden fying DRG classifi ca on

    Box 3. Development of Ghana’s patient classification system

    The Ghana Na onal Health Insurance Authority (NHIA) developed a CBG system –
    called the “Ghana DRG system” or G-DRG – to be used for payment, star ng in January
    2007. A team of experts from the Ghana Health Service and health workers – including
    doctors, nurses, midwives and pharmacists – took approximately six months to develop
    the classifi ca on algorithm. The G-DRG has been applied for payment in all facili es
    receiving payments from the NHIA since April 2008.

    The development of the classifi ca on system was based on the following steps:

    1. The list of the principal diagnoses to be covered by the new payment system were
    grouped into major diagnos c categories (MDCs). Special es refl ected in the MDCs
    were: adult medicine, paediatrics, adult surgery, paediatric surgery, ear nose and
    throat, obstetrics and gynaecology, den stry and ophthalmology.

    2. Within these MDCs, diagnoses were further grouped according to whether a surgical
    procedure is required or not.

    3. For diagnoses needing a surgical procedure, further grouping steps were introduced,
    namely:

    • grouping according to the major organ system if applicable and

    • grouping according to the complexity and type of procedures to be performed.

    4. Diagnoses which did not need a surgical procedure were grouped by principal
    diagnoses based on major organ systems.

    5. The obtained case groups were further fi netuned by considering similari es of resource
    use in providing care to the pa ents in order to create economically homogenous
    groups.

    The result was the G-DRG system composed of a manageable number of 546 inpa ent
    DRGs which capture most inpa ent cases treated in Ghanaian health facili es.

    the VSS and health care providers.

    Therefore, in 2012, the Ministry of Health decided to launch a pilot project in all provincial
    and district hospitals – which were all secondary care hospitals – in Ninh Binh province
    to assess how the VSS can pay providers using DRG payments. The pilot DRG system was
    based on the Thai DRG variant. The pilot served to fi netune this classifi ca on system to
    the Vietnamese context, to determine which classifi ca on variables should be used for
    grouping cases, and to develop related case-group weights. The result was a Viet Nam-
    specifi c classifi ca on system and grouping algorithm with around 400 DRGs. These
    are defi ned through principal diagnosis, procedures, comorbidity and pa ent clinical
    complexity level, and are further specifi ed for some case groups by age, sex, length
    of stay, body weight and type of hospital discharge. Pilo ng of this new system is s ll
    ongoing and will expand to 34 selected hospitals in fi ve provinces.

    The pilot phase to develop the Vietnamese DRG system took much longer than expected.
    One reason was the need to link the defi ni on of case groups and the services they
    include to clinical pathways. These had yet to be developed in line with the Ministry’s
    plan for people’s health protec on, care and promo on. This process took several years
    and is expected to be fi nalized in 2020.

    Costs for providing health services can
    be diff eren ated into several cost items,
    such as salaries, medicines, consumables,
    equipment or capital. These cost items can
    be paid for through various fi nancial fl ows.
    Some CBG systems do not pay for and do not
    include salary costs, which o en con nue
    to be provided by the Ministry of Health
    through supply-side fi nancing. Capital
    costs are excluded from most CBG systems
    because decisions on capital investment
    and expensive or high-tech equipment
    o en require a long-term perspec ve and

    are usually part of a na onal investment
    plan (37). For example, in Austria, Czechia,
    Finland, Germany and Ireland, capital costs
    of providers are covered through addi onal
    alloca ons and are therefore not included
    in the DRG payments (37). However, CBG
    payments to private providers might have
    to refl ect capital cost as well.

    The larger the share of costs covered
    under the CBG payments, the more room
    there is for the provider to rellocate these
    resources internally. Moreover, fi nancial

    3.3. WHICH COST ITEMS CAN BE INCLUDED IN THE CBG
    PAYMENT?

    20 HEALTH FINANCING GUIDANCE NO. 10

    incen ves created by the CBG payments
    might not be strong enough to change
    provider behaviour if only a small share of
    the total cost of health services is paid by
    the CBG system; and hence the impact of
    a CBG payment system and its contribu on
    to making purchasing more strategic would
    be reduced (4).

    Including only selected cost items in the
    CBG payment system makes it possible
    to share the expenditure risk of unknown
    health service use between the provider
    and the purchaser. On the one hand, lower

    u liza on rates would not necessarily lead
    to a facility’s closure if staff and equipment
    costs are funded from other sources. This
    can allow providers to con nue opera ng
    in remote areas with low u liza on and
    with limited ac vity-based payments. On
    the other hand, par al cost inclusion in
    CBG payment limits the poten al of the
    CBG system to restructure and op mize
    the provider market – i.e. aligning hospital
    bed capacity with the size and needs of the
    popula on in its catchment area (4).

    Countries usually import DRG systems
    from another country, including the related
    grouping algorithm and, if applicable,
    related so ware. There are no documented
    cases of a country buying a (simpler) CBG
    system from elsewhere. However, buying
    or making a DRG grouping algorithms and
    grouper so ware is not an either-or choice.
    A country can buy and apply without
    further adjustment; 2) buy and adapt to
    the context, leading to the development
    of a country-specifi c DRG variant; 3) copy
    (without buying, if this op on is available)
    and adjust to the country’s context; or 4)
    develop its own DRG system for its own
    se ng. Even though some countries
    have ini ally bought a DRG system, they
    have later developed their own system or
    changed to another DRG variant if those
    have been a be er fi t for the (evolved)
    country context.

    The USA began developing a DRG system
    in the 1970s and introduced it as a

    payment method in 1983. Other systems
    developed from new were those of the
    United Kingdom (1992), Austria (1997) and
    Netherlands (2005). However, most other
    countries developed their DRG systems on
    the basis of an exis ng DRG variant (42).
    Busse et al. (2011) provide an overview of
    which European countries developed their
    own DRG system and which ones chose
    to import an exis ng variant (Table 2) (5).
    Since a DRG system requires constant
    adjustment, most of the countries that
    ini ally imported a DRG system will develop
    their own country-specifi c variant over
    me (28). Box 5 describes how the Islamic

    Republic of Iran adopted an imported
    grouper to develop its own DRG system.

    Box 5. Buy and make in Iran: adopting an imported grouper to develop its own DRG
    system

    Iran has been using fee-for-service payments and case-based payments for 90 procedures
    to pay hospitals since the 1990s. In order to improve effi ciency and produc vity, u liza on
    management and introduce performance-based budge ng, the Iranian Ministry of
    Health decided in 2015 to explore the introduc on of a DRG payment system for case-
    based hospital payment and budget alloca on. As a start, diff erent DRG variants were
    assessed for how they would fi t with the Iranian health system and context. Following
    a consulta on process with na onal and interna onal DRG experts in 2016 and a
    qualita ve research project carried out by Iranian health economists, the Ministry of
    Health iden fi ed the Australian Refi ned DRG variant (AR-DRG) as the most appropriate
    op on. The reasons for this decision were the high quality and availability of AR-DRG
    documenta on, the availability of technical assistance and support from the Australian
    Independent Hospital Pricing Authority (IHPA) and grouper suppliers, the widespread
    use of the AR-DRG system in many countries and a long history of refi nement and regular
    updates.

    Iran signed a confi den ality deed (a commercial contract and agreement which specifi es
    if, how and for which purpose informa on can be used or passed on) with the IHPA
    to evaluate the AR-DRG system in rela on to the Iranian context. According to this
    contract, Iran has access to the AR-DRG version 9.0, which is based on ICD-10 Australian
    Modifi ca on and the Australian Classifi ca on of Medical Interven ons (ACHI), and the
    related Australian Coding Standards.

    The development and implementa on of the DRG system is taking place in three phases.
    During the fi rst phase of tes ng, data compa bility between the AR-DRG requirements
    and data currently included in medical records was assessed in a number of public
    hospitals. Currently, the second phase is focusing on system adapta ons needed to run
    a DRG system. Those include adapta ons to classifi ca ons and clinical coding, provider
    payment policies, performance and quality management procedures, price and tariff –
    se ng as well as IT and health informa on management systems. Three universi es
    and two AR-DRG grouper suppliers are suppor ng some 50 hospitals in managing
    DRG-based budget alloca ons and in monitoring performance and clinical prac ces
    at physician and hospital levels. The third phase entails the development of an Iran-
    specifi c DRG variant by adjus ng and changing the AR-DRG case-group weights and the
    classifi ca on algorithm to the needs of Iran.

    Iran aims in the long term to develop its own payment system based on an integrated
    care approach encouraging providers and purchasers to deliver and buy comprehensive
    healthcare packages in order to improve the health-care delivery process.

    Box 6. Gradual development of a CBG system in Kyrgyzstan

    The Mandatory Health Insurance Fund of Kyrgyzstan introduced a case-based payment
    system for public providers in 1997 as part of broader health fi nancing reform. At the
    me, CBG payments were addi onal on top of line-item budget alloca ons. The CBG

    payments were accompanied by performance-based staff bonuses. Higher CBG base
    rates are paid for pa ents who are exempted from formal co-payments.

    The ini al classifi ca on algorithm was simple. There were 28 case groups mostly
    following the hospital department structure or clinical sub-speciali es, which were
    further divided according to whether a pa ent had been in the intensive care unit or not.
    Thus, the CBG system consisted of 56 case groups in total. This ini al set of case groups
    was used for about 20 months.

    A fi rst revision increased the number of case groups to 144 and eliminated the direct
    connec on between an intensive care unit stay and a higher payment rate. In 2003,
    the system was revised a second me to replace ICD-9 diagnosis coding with ICD-
    10. Nowadays, only principal diagnosis and the main (i.e. most resource-intensive)
    procedures are used for the CBG assignment. The only addi onal characteris c taken
    into account is the pa ent’s age (< 15 years, ≥15 years). In total there are now 284 CBGs. Another revision is currently ongoing and has three main objec ves: 1) to update the classifi ca on of surgical procedures, 2) to review the classifi ca on algorithm to improve clinical homogeneity by now using main diagnos c categories as the fi rst classifi ca on step, and 3) to reduce age-related splits in case groups.

    Triin Habicht

    With regard to simpler CBG systems,
    countries usually develop their own
    version. Examples include Ghana, Morocco,
    Philippines and Tunisia (16, 17, 41, 44).
    Likewise, Kyrgyzstan decided to develop its
    own CBG system by combining diagnosis for
    medical cases and procedures for surgical

    cases and then further spli ng them by
    age (Box 6). In such a system the number of
    groups will be lower and the development
    of a classifi ca on algorithm simpler, as will
    the cos ng for rela ve case weights. For
    such less complex CBG systems, grouping
    so ware is not necessarily required (4).

    The most complex part of a DRG system
    is the development of the algorithm for
    alloca ng cases to case groups. Impor ng
    a classifi ca on algorithm from another
    country rather than developing one’s
    own can reduce me and costs. Buying a
    classifi ca on algorithm usually includes
    acquiring an accompanying grouping
    so ware with a licence agreement. Some
    classifi ca on algorithms are open source,

    are freely available/downloadable and
    can thus be adjusted to the country
    context as needed. Other algorithms have
    more restric ons. Most DRG systems
    are developed by public or semi-public
    organiza ons, but private companies also
    develop and sell classifi ca on algorithms
    and so ware. If a DRG variant, including
    a related algorithm and/or so ware, is
    bought, it is important that the classifi ca on

    24 HEALTH FINANCING GUIDANCE NO. 10

    algorithm is also shared openly and is
    adjustable, with the developers being
    responsive to the needs of the buyer. Some
    country experiences have shown that
    merely receiving the grouping so ware
    without insights into the classifi ca on
    algorithm and without op ons to adjust it
    will create signifi cant problems and may
    lead to a huge loss in me and spending.

    Consequently, when buying a DRG system
    it is very important to have insight into the
    classifi ca on algorithm and to be able to
    adjust the algorithm as the system evolves.

    Further factors to consider when deciding
    whether to buy a DRG system or create one’s
    own are outlined in the following sec ons.

    An exis ng classifi ca on algorithm can be
    adopted if there are suffi cient similari es
    in the classifi ca on systems, cost structures
    and the treatment prac ces between
    the DRG system to be imported and the
    envisaged classifi ca on system. The larger
    the diff erences, the more diffi cult and
    expensive it will be to adjust the imported
    system. The envisaged DRG variant should
    cover the same levels (types) of health
    facili es and the same categories of
    services as the imported DRG system.

    With respect to classifi ca on systems, one
    important point is the underlying coding
    for diagnoses and procedures. If those are
    not the same, data has to be mapped to the
    imported system before it can be used to
    run the imported grouping algorithm. As
    most DRG variants are based on ICD coding
    for diagnoses, grouping by diagnoses
    makes exis ng classifi ca on algorithms
    more easily applicable. Comparison of
    several country DRG variants has shown
    that the major diagnos c categories tend
    to be similar and that they are aligned with
    medical special es (36).

    O en, however, there are larger diff erences
    between countries in the treatment
    prac ces and how they are coded as well

    as in the cost structures (5). The share of
    cost on human resources, for instance,
    tends to be larger in high-income countries
    than in middle-income countries. To
    assess diff erences in cost structures, the
    classifi ca on algorithm can be tested
    with exis ng informa on. Alterna vely,
    clinical experts can advise as to how far
    their own treatment prac ces diff er from
    the treatment prac ces that underlie the
    grouping logic of the imported system.

    The adequacy of a DRG variant for the
    context of an impor ng country can
    be evaluated by using data that are
    available (such as from hospital discharge
    summaries). The required informa on
    should include diagnosis (primary and
    secondary), procedures and pa ent
    characteris cs that can be used to generate
    coded informa on. The coded informa on
    can be fed into the classifi ca on algorithm
    to analyse the extent to which cases are
    allocated to the appropriate case groups.
    However, such evalua ons are costly if
    data are not available electronically. These
    evalua ons are o en a fi rst step towards a
    pilot phase (36). An account of Georgia’s
    experience in this is contained in Box 7.

    25PREPARATION AND DESIGN PHASE

    A DRG system relies on pa ent data
    collected by a well-func oning informa on
    management system. To use an imported
    DRG system, health facili es must
    rou nely collect pa ent data at a similar
    level of detail. If no strong pa ent
    informa on management system exists,
    the development of a CBG system that uses
    exis ng data is a more viable op on (4, 29).

    Impor ng a DRG system and its classifi ca on
    algorithm can be useful if cost data are

    lacking, and if the imported system
    includes rela ve weights that can be used
    as cost assump ons and then be gradually
    adjusted. Using these cost assump ons
    can reduce the need for addi onal cos ng
    studies.

    Table 3 compares the op on of developing
    a country-specifi c CBG system or DRG
    system to the transi onal strategy of fi rst
    impor ng an exis ng system and then
    gradually adjus ng it.

    Box 7. Matching classification systems and electronic claims data format to
    facilitate the adoption of the NordDRG variant in Georgia

    Georgia applied a country-specifi c CBG payment system with a high number of case
    groups defi ned through a combina on of ICD-10 and the Nordic Medico-Sta s cal
    Commi ee (NOMESCO) classifi ca on of surgical procedures. Over the years this locally
    built system has been fi netuned to limit the number of case groups (e.g. some areas of
    cardiology) but there has been no comprehensive solu on for all clinical areas.

    In mid-2017 the Ministry of Internally Displaced Persons from the Occupied Territories,
    Labour, Health. and Social Aff airs of Georgia decided to introduce a DRG system for
    payment. A feasibility study revealed that the NordDRG system is suitable for Georgia as
    health providers already use the same surgical procedures classifi ca on system as the
    Nordic countries. Similarly, Georgia applies ICD-10 which is also used by the NordDRG
    system. Thus, there was no need to introduce a new primary classifi ca on system.
    Consequently, the pragma c op on for Georgia is to adopt the NordDRG grouper, while
    keeping the possibility of adding country-specifi c adjustments in the future.

    Another important suppor ve factor for adop ng the NordDRG system is the availability
    of digital pa ent-level claims data which include all informa on required by the
    NordDRG classifi ca on algorithm. However, some eff orts are needed to further improve
    data quality in parallel to implemen ng the new system. By the end of 2018, the Nordic
    Casemix Center had developed the Georgian version of the NordDRG classifi ca on
    algorithm. Transi on to the new system began in mid-2019 (45).

    phase, the Australian Classifi ca on of Medical Interven ons (ACHI) was introduced
    and the ICD-10 version in use was updated. Lithuania has aimed to develop its own
    case-group weights from the very beginning. Un l now all acute care hospitals submit
    annually aggregated cost data reports by 16 main cost categories to the Na onal Health
    Insurance Fund (NHIF). These na onally collected cost data are combined with the cost
    structure of each DRG group taken from the Australian rela ve case-group weights.
    On this basis, the NHIF constructs country-specifi c case-group weights. These follow
    the cost structure of the Australian DRG system, but the cost related to diff erent cost
    categories is calculated on the basis of data from Lithuanian hospitals. The weakness
    of this methodology is that it follows the cost structure of the Australian health system
    which, in some cases, may diff er signifi cantly from the Lithuanian reality. Eventually a
    more systema c approach to validate case group weights was needed.

    Therefore, in 2015, the NHIF ini ated the pa ent-level cos ng project in 15 hospitals
    that represent the whole scope of acute inpa ent care. The project has a triple aim:

    1. to develop Lithuanian DRG case-group weights refl ec ng, the cost structure of
    Lithuanian hospitals;

    2. to analyse hospital sector performance; and

    3. to give hospitals the possibility to analyse their own cost data to fi nd areas for
    improvement.

    The NHIF has developed a standardized cost accoun ng so ware and provides hands-on
    technical guidance to support par cipa ng hospitals. The cos ng project is expected to
    provide results in 2020. First experiences suggest that the complexity of the pa ent-level
    cos ng system requires more me for implementa on at hospital level than ini ally
    planned.

    Box 9. A mix of imported and locally-developed case-group weights in Estonia

    In 2001, the Estonian Health Insurance Fund (EHIF) decided to implement a DRG payment
    system and to adopt the NordDRG system.

    In order to develop and calculate case-group weights that are country-specifi c, two
    approaches were pursued. The fi rst one was to calculate case-group weights based on
    exis ng fee-for-service tariff s. Claims with fee-for-service informa on were available in
    digitalized form for all hospitals since 2000. DRG case-group weights were calculated
    on the basis of data from January to June 2003. Since tariff s include all cost categories
    (personnel, consumables, overheads and capital costs) and providers are allowed
    to charge only the offi cial co-payments from the pa ents, these data gave a good
    approxima on of rela ve costs. The second approach was to use the case-group weights
    from the American Health Care Financing Administra on (HCFA) DRG variant.

    Simula ons with data sets for both methods were undertaken and discussed with the
    DRG Advisory Commi ee in 2003. This recommended to use Estonia’s own case-group
    weights, except for DRGs with a low case number (less than 30) for which the HCFA
    weights should apply.

    DRG payments were then par ally introduced in 2004. The DRG base rate was calculated
    using the overall available budget, thus assuming budget neutrality. DRG payment rates
    are not diff eren ated by hospital type. Teaching hospitals receive the same base rate as
    general hospitals, although their case mix index is higher since they treat rela vely more
    complex cases. The unifi ed base rate refl ects the assump on that pa ents in the same
    DRG group should have on average the same cost, regardless of where they receive their
    treatment.

    Un l now, Estonia has con nued to apply a similar methodology for DRG case-group
    weight calcula on. This is possible because DRG payments form 70% of total claims
    cost, while the other 30% is s ll reimbursed on the basis of fee-for-service. Since 2006,
    fee-for-service tariff s have been calculated by using selected hospitals’ cost data and
    applying an ac vity-based cos ng methodology.

    Source: reference (47)

    The base rate is calculated on the basis of
    the overall available budget for the health
    services remunerated through CBG and

    the overall expected case mix for a specifi c
    period (generally the budget year). As the
    precise volume of services to be provided is

    To calculate case-group weights, the
    average cost of trea ng a case within every
    case group must be determined. While all
    cost informa on is useful, it is specifi cally
    required for the cost categories that are
    included in and paid by the CBG system.

    Box 10. PhilHealth’s plan to institutionalize the collection of cost information

    The Philippine Health Insurance Corpora on (PhilHealth) started its refl ec on and
    development of a DRG payment system in 2009 in order to move away from fee-
    for-service payments. However, one major challenge was the lack of detailed and
    disaggregated cost informa on to inform rela ve case-group weights. Collec on of cost
    data started in 2009 using a top–down cos ng tool. However, these cos ng studies were
    not systema cally conducted. Data collec on was further impeded by a lack of electronic
    data collec on, the absence of na onal standards for hospital accoun ng, reluctance
    of providers to provide transparent informa on and limited capacity and experience in
    conduc ng cos ng studies.

    Ten years later, in 2019, the PhilHealth Board approved a long-term comprehensive
    plan with the objec ve of ins tu onalizing the collec on, analysis and policy use of cost
    informa on. The plan includes three major pillars, namely:

    FT

    31PREPARATION AND DESIGN PHASE

    Box 10. (Contd.)

    First, PhilHealth has compiled a cos ng toolkit which includes data collec on forms,
    training manuals, communica on templates to facilitate informa on exchange between
    local PhilHealth offi ces and providers, and evalua on forms. These standardized tools
    will allow for collec ng comparable data across health-care providers.

    The second pillar consists in the ins tu onaliza on of the cost informa on collec on
    and valida on process. Providers have to submit cost informa on regularly and this
    requirement is part of accredita on standards and the provider contract. The submi ed
    data will be analysed by PhilHealth in collabora on with academic or research
    ins tu ons so as to develop and update cost weights. It will also be fed into a dialogue
    between PhilHealth, the Department of Health, providers and pa ent representa ves.
    This can contribute to refl ec ons on the aff ordability of the benefi ts as well as provide
    informa on about the quality of health services. Moreover, it can serve as feedback
    to providers and can enable communica on regarding the results of the data analysis
    for mutual accountability between PhilHealth and providers, and the joint defi ni on of
    priori es.

    Finally, the third pillar focuses on strengthening IT systems and capaci es to automate
    and reduce as far as possible the repor ng burden.

    The implementa on of the cos ng informa on collec on plan is an cipated for 2020.
    This will allow PhilHealth to collect cost informa on from providers rou nely in order to
    develop case-group weights as a crucial element of a DRG payment system.

    Melanie Coronel San llan

    Data are ideally collected from the cost-
    accoun ng system at hospital level which
    enables the treatment cost per pa ent
    to be iden fi ed and, if needed, facilitates
    the alloca on of indirect costs incurred
    by hospitals to individual cases. Such
    detailed informa on may o en not be
    collected rou nely, especially prior to
    the roll-out of a CBG system. Some form
    of cost es ma on or modelling may
    therefore be needed (29). The quality and
    granularity of available cost data are likely
    to increase over me while capaci es
    and methodologies for the collec on of
    cost data become ins tu onalized. The

    use of cost informa on for payments will
    incen vize providers and purchasers to
    improve data quality. The approaches
    below outline diff erent methods for
    genera ng cos ng data. A combina on of
    these approaches can be an eff ec ve way
    of closing data gaps.

    Introduc on of cost-accoun ng systems
    in a sample of providers. Although it
    allows for cost informa on to be collected
    rou nely, introducing a cost-accoun ng
    system that enables pa ent data to be
    linked to cost data at the necessary level
    of disaggrega on can be costly. Some

    costly. Some ostly. Som

    countries chose to implement such a system
    only in a sample of providers which receive
    a compensa on payment for the addi onal
    administra ve burden. The sample should
    be representa ve so that the data collected
    will provide adequate informa on for
    designing and upda ng payment rates (37).

    Cos ng studies. Cos ng studies can
    be conducted if data are lacking or if
    the informa on available from rou ne
    data collec on is incomplete. Again, the
    provider sample for the cos ng study must
    be representa ve of all providers that will
    be included in the payment system.

    Use of fee-for-service payments. If fee-for-
    service payments are replaced by a CBG
    system, the exis ng fee schedules can be
    used to es mate the costs of diff erent case
    groups. This avoids costly collec on of cost
    data through specifi c studies. However, it
    should be considered carefully because fee-
    for-service payments may include historical
    ineffi ciencies. In a fi rst phase this might
    limit the cost-containment poten al of the
    CBG system, but CBG payments that are
    similar to previous rates can also facilitate
    acceptance of the new system by providers.
    For example, Estonia, and Thailand used
    fee-for-service rates as a star ng point for
    developing rela ve cost weights (28, 47).

    Impor ng cost assump ons from an
    exis ng grouper. This op on is available

    when a country imports a grouper that
    includes rela ve case-group weights.
    These assump ons can be used when
    introducing the system and can then be
    gradually fi netuned. The impor ng country
    should then make adjustments with a
    focus on the most frequent cases or the
    main drivers of treatment cost (12). It is
    important to undertake impact assessment
    to explore the impact and iden fy if further
    adjustments are needed.

    Regardless of which method or mix of
    methods is used to generate cost data
    for the design of the CBG system, cost
    assump ons and calcula ons must be
    constantly updated to refl ect changes
    in cost structures, innova ons and the
    introduc on of new technologies.

    Costing_Toolkit_Interactive_FINAL , accessed 28 September 2019).

    33PREPARATION AND DESIGN PHASE

    The basic idea of a CBG system is to pay
    the same for each case within the same
    group. However, adjustment factors can
    be used to raise or lower CBG payments to
    compensate for factors which cannot be
    captured by the classifi ca on system itself
    (8, 12), such as the remoteness of a health
    facility or other specifi cs. The adjustment
    factors can be considered as addi onal
    coeffi cients in the formula to determine
    the case payment (22), and must align with
    policy objec ves. The following adjustment
    factors are found in prac ce:

    Geographical criteria: Regional diff erences
    within countries (e.g. diff erences in prices
    or transport distances) result in diff erent
    input costs for providers. A purchaser may
    also want to encourage service provision
    in remote areas or compensate for lower
    provider income resul ng from lower
    u liza on rates in sparsely populated areas
    (22). These diff erences can be addressed
    with a geographical adjuster.

    Equity criteria: Providing treatment to
    pa ents who belong to defi ned vulnerable
    popula on groups can be more resource-
    intensive. To improve equity in access to
    health services, regulators or purchasers
    might want to off er fi nancial incen ves
    to providers to treat such pa ents. For
    instance, in the Australian hospital payment
    system an adjustment factor is added
    to provide higher payments for services
    provided to indigenous Australians (49).

    Provider level adjustments: Some
    systems might apply diff erent payment
    rates for diff erent providers. For instance,
    there could be higher rates for hospitals
    using more specialized technologies or
    equipment. Adjustment factors could also
    serve to compensate teaching hospitals
    for their teaching ac vi es, which are
    diffi cult to refl ect in a CBG payment system
    classifi ca on. However, such adjustment
    coeffi cients, if not carefully designed, may
    create the wrong incen ves. If secondary
    or ter ary facili es receive higher
    payments for simple treatments which
    can be provided at lower cost at lower-
    level facili es, there is less incen ve for
    providers to direct pa ents to lower-level
    facili es (7). Such adjustment factors might
    also encourage providers to invest in high-
    tech equipment to obtain higher payments.

    Hospital-specifi c adjustments: When a
    CBG payment system is introduced, some
    hospitals might face signifi cant reduc ons in
    their revenues; for instance, their previous
    overall budget might have been higher than
    the CBG payment system’s remunera on
    for their ac vity level. Specifi c hospital
    adjustments can be used for an interim
    period (with a clear phasing-out plan) to
    ensure that the hospital’s income under
    the new CBG system does not diverge too
    much from its previous level of funding.
    However, the hospital-specifi c adjustments
    should not become permanent as this
    would undermine the objec ve of the CBG
    system (22).

    3.7. WHICH ADJUSTMENT FACTORS CAN BE CONSIDERED
    TO MODULATE THE CBG PAYMENT?

    FINA
    L DR
    AFT

    34 HEALTH FINANCING GUIDANCE NO. 10

    The shi to a CBG payment system creates
    incen ves to increase the number of cases
    and can therefore escalate expenditure.
    In this regard, several approaches exist
    to share the fi nancial risk of increased
    case numbers between purchasers and
    providers.

    The fi rst approach is to set payment rates
    per case prospec vely and to apply a
    volume cap or a budget cap. This cap is

    based on how much can be covered with
    the available budget. Purchasers and
    providers need to nego ate this cap in
    advance during the contrac ng process
    (24, 29).

    Figure 5 illustrates how total revenue per
    provider develops under prospec ve se ng
    of payment rates and in various scenarios
    with and without a volume or budget cap.

    When there is no volume/budget cap, the
    provider revenue increases without limit
    with the number of cases treated.

    Under a hard budget or volume cap, any
    cases that exceed the agreed budget cap
    per provider within a budget period will
    not be reimbursed. Providers have an
    incen ve once the cap is reached to limit
    cases or ra on services by crea ng wai ng
    lists or making referrals. The fi nancial risk
    associated with higher-than-expected
    volume lies with the provider (24).

    Under a so budget cap, addi onal services
    will be reimbursed but at a lower payment
    rate; the base rate is also commonly
    reduced in the case of DRGs. The payment
    rate can be set so that it is slightly below,
    equal to or above the marginal costs for
    trea ng a case. To encourage providers to
    limit the number of cases they treat, the
    rate would have to be equal to or below
    the marginal cost for trea ng the service.
    The fi nancial risk of higher-than-expected
    volume is shared between provider and
    purchaser (24).

    3.8. SHOULD CBG PAYMENTS BE LINKED TO A VOLUME OR
    BUDGET CAP AND, IF SO, HOW?

    budget caps

    FINA
    L DR
    AFT

    35PREPARATION AND DESIGN PHASE

    The second approach is to set payment
    rates retrospec vely and to adjust payment
    rates in order to cover with the available
    budget the en re volume of services that
    have been provided. Providers collect
    points that refl ect the rela ve severity
    of the cases treated. At the end of the
    budge ng period, usually the budget year,
    the available budget is divided by the total
    of points accumulated by all providers
    covered by the payment system in order
    to determine the base rate (24). This point
    system is used, for instance, by the Universal
    Coverage Scheme in Thailand (51).

    A third op on is to use the CBG payment
    rates and expected volume or the case mix
    index as the basis for se ng a prospec ve
    fi xed budget covering a defi ned period.
    While this is a way to inform the budget-
    se ng process, it in fact becomes a cap.
    Importantly, the budget will not be adjusted

    in line with the actual volume or case mix
    of services provided. The provider will bear
    the fi nancial risk of higher ac vity levels
    but will also keep any savings if the ac vity
    is lower than expected. When the budget is
    set, case volumes from previous years are
    taken into account in order to weaken the
    incen ve to reduce the number of cases
    (e.g. by rejec ng or referring pa ents,
    or cream-skimming for pa ents with less
    severe cases) (24).

    Whichever budget or volume cap approach
    is chosen, the predictability of the budget
    is important for both providers and
    purchasers. Tight budgets may make
    providers look for other income such as
    balance billing or informal payments. Strong
    administra ve controls and monitoring
    are therefore needed to minimize such
    prac ces, as noted in Sec on 4.3 and
    Sec on 4.5.

    MONITORING AND CONTINUED
    REVISION

    36 HEALTH FINANCING GUIDANCE NO. 10

    This sec on highlights ques ons about implementa on that must be addressed during the
    pilot and implementa on phases.

    Introducing a CBG system usually requires
    signifi cant adjustments to fi nancial
    management systems and procedures at
    provider level, including in informa on

    collec on, claims management and human
    resource management. Specifi c training
    may also be needed to support providers.

    4.1. WHAT CHANGES ARE REQUIRED AT PROVIDER LEVEL
    WHEN INTRODUCING A CBG SYSTEM?

    Changes in fi nancial fl ows to providers may
    be signifi cant, especially if CBG payments
    mean that providers are to be paid by
    outputs. Where the CBG payment system
    replaces input-based budget alloca ons,
    providers will have to modify their internal
    budge ng and fi nancial procedures.
    However, providers may s ll have to develop
    budget plans and report expenditure
    following input-based budget structures. In

    contrast, a shi from fee-for-service to CBG
    payments might require fewer adapta ons
    in fi nancial management. With more
    detailed informa on on hospital ac vity,
    the facility management might s ll be able
    to reshuffl e resources to be er refl ect
    the workload of each department. Facility
    managers have to be able to lead such
    transforma ons without risking disrup ons
    in service provision (30).

    The CBG classifi ca on algorithm may
    require data that are not yet collected by
    providers or data at levels of disaggrega on

    not yet available. However, clinical
    and pa ent data elements of suffi cient
    quality are needed for many purposes in

    37IMPLEMENTATION, MONITORING AND CONTINUED REVISION

    The introduc on of new repor ng
    procedures requires changes to
    administra ve processes. Purchasers and
    providers will have to provide training to
    ensure that staff are familiar with the new
    system. Training topics include DRG system
    design and grouping algorithms, the use of
    primary classifi ca ons, coding standards
    and rules, coding quality, repor ng, and
    DRG-specifi c performance monitoring (28).
    Providers may also hire specialized coders

    whose role is to extract the necessary
    informa on from medical records and to
    code it as required by the classifi ca on
    system. Coders will relieve doctors and
    nurses of these administra ve tasks.
    Likewise, regular training, with feedback, is
    needed to improve the quality and accuracy
    of coding (7). Box 11 the measures taken

    addi on to implemen ng a CBG system.
    The introduc on of a CBG payment
    system should not lead to a situa on
    where providers focus only on collec ng
    informa on on those variables or codes
    that infl uence payment rates at the expense
    of a more comprehensively documented
    pa ent history. The introduc on of CBG
    payments can incen vize data collec on
    (4).

    When a grouper so ware is used, data
    collected through hospital informa on
    management systems must be interoperable

    with the so ware. The adapta on may
    entail signifi cant cost. If not already used
    by providers, computerized (informa on)
    management systems can be developed
    and introduced in parallel to ensure that
    data are standardized and respond to
    the needs for medical documenta on
    on pa ent cases, repor ng on health
    sta s cs, hospital management and claims
    processing. Developing a separate system
    that serves only the CBG increases the
    repor ng burden of providers and should
    be avoided (4).

    Box 11. Introduction of ICD-10 in the Philippines and training measures

    The Philippines Department of Health decided in 1998 to introduce ICD-10 as a pa ent
    classifi ca on system in hospitals and registries in order to improve the quality of
    morbidity and mortality sta s cs from health-care providers. Various measures were
    introduced to accompany this process:

    1. A na onal ICD-10 Technical Working Group was created in 1999 consis ng of
    representa ves from the Department of Health, the Philippine Sta s cs Authority,
    PhilHealth, the Associa on of Philippine Medical Colleges, the Associa on of
    Municipal Health Offi ces of the Philippines and selected hospitals. The composi on of
    this working group has since been revised to include other offi ces that are involved in
    genera on of health sta s cs.

    Box 11. (Contd.)

    2. Various training courses for diff erent target groups were developed to build up capacity
    to implement ICD-10. The ICD-10 Training of Trainers is a two-week course designed
    for poten al trainers from the Department of Health and its a ached agencies. There
    is also a fi ve-day ICD-10 training course for coders that is off ered to medical records
    staff , government regulatory offi cers, sta s cians and local civil registrars who use
    morbidity and mortality data, in addi on to hospital coding staff . A separate three-
    day course was specifi cally designed for medical staff who are responsible for the
    documenta on related to pa ent records.

    3. Through Administra ve Order No. 47 s. 2000, the Department of Health mandated
    the use of ICD-10 for recording all diagnoses of pa ents. The licensing requirements
    for hospitals were updated to include the full implementa on of ICD-10, including
    procurement of ICD-10 books, use of ICD-10 in all medical records and hospital sta s cs
    and repor ng, and the 5-day training course of medical records offi cers. PhilHealth
    complemented the department’s Administra ve Order with its own informa on on
    the use of ICD-10.

    These eff orts resulted in be er-quality health data. However, there remain several concerns
    – such as a fast turnover of trained coders (due to high demand in the interna onal
    labour market) and inadequate IT infrastructure in providers’ and regulatory offi ces. It
    will be important to enhance understanding among senior managers in PhilHealth and
    the Department of Health of, among other issues, the importance of good data quality,
    the need to improve monitoring and evalua on and the importance of strengthening
    penal es and sanc ons for noncompliance with ICD-10 in order to further improve
    coding quality in the Philippines.

    The introduc on of a CBG system can be
    facilitated by an implementa on plan that
    clearly defi nes the strategy and melines
    for transi oning to the new system so that
    purchasers and providers can prepare for
    changes in fi nancial alloca ons.

    To ensure provider buy-in and to avoid
    disrup ons in service delivery, most

    countries have chosen to phase in CBG
    payments gradually. This helps in managing
    fi nancial risks to providers by avoiding
    signifi cant changes in provider income
    from one year to the next. It also allows for
    gradual standardiza on of payment rates
    if signifi cant varia ons existed prior to the
    introduc on of CBG payments (14).

    4.2. HOW SHOULD THE CBG SYSTEM BE PILOTED AND
    PHASED IN?

    FINA
    L DR
    AFT

    39IMPLEMENTATION, MONITORING AND CONTINUED REVISION

    Various ways of phasing in and pilo ng can
    be combined.

    Shadow billing or shadow budgets: If
    a well-func oning computerized claim
    system is in place and can be used for CBG
    claims, immediate countrywide pilo ng
    through shadow payments is possible,
    especially in smaller countries. Hospitals
    start case repor ng according to the CBG
    system and the respec ve payment is
    calculated. During an agreed transi on
    period, the actual payment s ll follows
    the previous provider payment method.
    This allows suffi cient me to adjust the
    repor ng system and to allow providers
    to prepare for the upcoming changes in
    resource alloca ons (6).

    Gradual increase of the share of hospital
    income coming from CBG payments:
    One op on is for hospital revenue to be
    calculated according to both the case-
    based payments and the previous payment
    method. Ini ally a limited part of the case-
    based hospital budget (e.g. 20%) will be
    paid, while the remaining payment (e.g.
    80%) is allocated according to the previous
    payment method. The propor on of the
    budget based on CBG payments is then
    gradually increased (14). A second op on
    is to pay diff erent base rates per hospital or
    group of hospitals in order to avoid abrupt
    changes in hospital income. The base rates
    will then converge over me (28). This is
    diff erent from covering only certain cost
    items using CBG payments as discussed
    below. Here, payment calcula on and
    fi nancial management rules apply equally
    to the whole budget and there is no
    dis nc on between cost items.

    Extension of geographical coverage:
    The CBG system is piloted in one region
    only or in a limited number of hospitals.
    This geographical sample should be large
    enough to draw general lessons and/or
    to adjust the system to make it applicable

    to the whole country at a later stage. This
    can be based on voluntary par cipa on,
    as was the case in the Republic of Korea,
    but it should be noted that voluntary
    par cipa on has the risk that self-selec on
    may lead to a biased, nonrepresenta ve
    sample (14).

    Pilo ng CBG payment for one level of
    hospital only: In this op on the CBG system
    applies only to providers at a certain level of
    care, for example secondary health services
    only, or ter ary care only. This approach
    makes it more diffi cult to include other
    hospital levels at a later stage because cost
    structures tend to diff er between levels of
    care. In addi on, it may lead to diff erent
    payments for diff erent levels of facili es
    which is not in line with the CBG principle
    of paying the same amount for all cases in
    the same case group. This approach also
    carries the risk that providers may try to
    avoid trea ng pa ents by referring them
    without suffi cient jus fi ca on.

    Extension of hospital ac vi es covered:
    CBG payments can also be applied to
    a limited number of diagnoses and/or
    procedures – e.g. those with long wai ng
    mes or priority health services, as these

    would be services for which the purchaser
    wants to encourage increased provision.
    However, under this op on, providers have
    an incen ve to shi pa ents from services
    not covered by CBG to services covered by
    CBG if the la er are be er remunerated
    (14).

    Extension of cost items covered: Some
    CBG systems ini ally cover only the cost
    of consumables and medicines, and/or
    opera onal costs. Addi onal cost items –
    such as salaries, hospital administra on
    costs or equipment – can be gradually
    included over a defi ned me period.
    This approach helps to strengthen the
    management capacity of providers over
    me. It is a useful approach in se ngs

    FINA
    L DR
    AFT

    40 HEALTH FINANCING GUIDANCE NO. 10

    where providers have limited management
    capacity and where an easy-to-administer
    system is needed. However, the approach
    limits the eff ects by which a CBG system
    can trigger a restructuring of the provider
    market, although this may be an objec ve
    of the payment reform (14).

    Extension of popula on groups covered
    or pilo ng with one scheme only: The
    CBG payment system can be piloted for
    the treatment of pa ents covered under

    a specifi c scheme (as was the case in
    Thailand (35)) or for pa ents with specifi c
    characteris cs (i.e. pa ents over 70 years).
    The design of the pilot should avoid crea ng
    incen ves for cream-skimming of pa ents
    by providers (14). This op on should be
    considered carefully as it carries a high risk
    of discrimina on against pa ents whose
    treatment is covered by a less a rac ve
    payment system.

    CBG payments create incen ves for
    providers to increase the number of cases.
    This can lead to cost escala on or to the
    provision of high volumes of non-priority
    or unnecessary services. CBG payments can
    also incen vize under-provision of cases
    (52).

    Table 5 provides an overview of
    administra ve measures to address these

    problems. Three types of administra ve
    measures can be iden fi ed: budget or
    volume caps (for more informa on see
    Sec on 3.8), regular revisions of the CBG
    system (for more informa on see Sec on
    4.5), and direct control mechanisms (i.e.
    monitoring and audi ng) which are further
    outlined below.

    4.3. HOW CAN ONE COUNTER INHERENT PROVIDER
    INCENTIVES CREATED BY CBGS?

    When providers have incen ves to reduce
    the number of inputs per case, the quality
    of care can be compromised. Consequently,
    there will be a need to monitor quality-
    related indicators which commonly include
    length of stay, survival rates a er 3, 6 or
    12 months, and/or readmission for the
    same diagnosis. Performance in rela on to

    these indicators can be linked to payments
    where the informa on management
    system allows. In several countries,
    frequent monitoring was established at the
    beginning of CBG introduc on, including
    making key indicators publicly available on
    the purchaser’s website (28).

    Monitoring of key indicators

    FINA
    L DR
    AFT

    41IMPLEMENTATION, MONITORING AND CONTINUED REVISION

    Payments can be adjusted for outliers
    regarding length of stay. As an example,
    addi onal payments can be allocated
    to complex cases with a length of stay
    signifi cantly above the average, or reduced
    rates could apply to inpa ent stays that are
    shorter than a certain threshold (12, 52).

    Addi onal payments could also be allocated
    for cost-outliers. Some CBG systems group
    those cases into a pre-MDC group in the
    fi rst step of their classifi ca on algorithm.
    Addi onal payments for cost outliers can
    also encourage the use of technological
    innova ons which tend to be more costly.

    Checking of audi ng claims, coding
    prac ce and data quality is important
    to reduce incen ves for upcoding. For
    example, audits of DRG payments in France
    iden fi ed errors in up to 60% of medical
    records analysed. This level of errors, for
    which there are various causes, can have
    signifi cant fi nancial implica ons. Unclear
    defi ni ons and insuffi cient training in
    coding can be reasons for disagreements
    on how diagnoses should be coded (12).

    Some coding mistakes can be considered
    as fraudulent. Consequently, procedures to
    check data quality systema cally should be
    in place and should include:

    • automa c checks of compliance with
    data standards and format during data
    collec on;

    • electronic and/or manual checks to
    ensure data and coding coherence before
    payments are processed;

    • retroac ve evalua on and analysis of
    data to detect varia ons and outliers
    that may refer to coding issues.

    Audit and control mechanisms require
    intensive capacity-building and a suffi cient
    budget on the side of the purchaser. A
    sound sampling methodology is important
    when selec ng claims to be audited since
    the audi ng of claims, including the coding
    of medical records, is very expensive.
    Electronic and system-wide checks of
    claims can to a certain extent reduce the
    need for detailed external audits (12).

    Audi ng of claims, coding prac ce and data quality

    A CBG system alone will not improve
    the quality of health services provided.
    However, countries have tried to integrate
    variables into their CBG system in order to
    incen vize providers to improve quality
    in service provision (23) at various entry
    points, namely:

    At the hospital level, the payment amount
    per case or the adjustment factors can be
    linked to the quality criteria that apply to
    all services delivered by the provider. These
    payments can be made con ngent upon
    the fulfi lment of selected quality criteria
    of an accredita on scheme or a quality
    assessment framework of the Ministry of
    Health (23).

    At the level of a CBG, the payment amount
    for a specifi c case group can be condi onal
    on respec ng specifi c quality or treatment
    guidelines for respec ve CBGs, with a
    focus on the procedural level. These could
    include standards related to availability of
    specialized medical equipment, suppor ve
    services to provide comprehensive care
    (e.g. onco-psychological care) or specialists.
    This would require specifi c treatment
    guidelines and/or iden fi ca on of best
    prac ces. It would also be more diffi cult
    to monitor as the purchaser would have
    to rely primarily on self-repor ng by the
    provider. As a result, such measures are
    not applied frequently. One example is
    from Germany, where a health insurance

    A CBG system needs con nuous review
    and adjustment to take account of changes
    in clinical processes and consump on of
    resources. This review process also allows
    for further fi netuning of the classifi ca on
    system and classifi ca on algorithm, and
    for further adjustment of case group
    weights and tariff s, including the base rate.
    Moreover, a review can also help decrease
    the scope for upcoding. This may lead to
    changes in the number and defi ni on of
    case groups and the rela ve cost weights.
    In addi on, changes may be needed

    that go beyond the CBG system, such as
    adapta ons to the data collec on system,
    the repor ng system or regula ons related
    to the implementa on of the CBG system
    (12, 32).

    It is helpful to establish a specifi c body or
    commi ee to take charge of the revision
    process and to propose and adopt
    adjustments. This commi ee should
    include at the minimum purchaser and
    provider representa ves. It is important
    to have clear rules and procedures for

    fund pays higher rates for coronary bypass
    surgery if the treatment scores higher than
    average on quality indicators that are part
    of the German external quality assurance
    system (23).

    At the individual pa ent level, the
    payment amount linked to a (pa ent)
    case will be adjusted according to defi ned
    quality criteria. The most common example
    is a reduced payment – or even none – for
    readmission under the same CBG within
    a certain me frame or nonpayment for
    comorbidi es that were not recorded at
    admission and are therefore assumed
    to result from treatment (23). These
    quality criteria are thus primarily linked to
    outcomes.

    Including quality criteria in the design of the
    CBG system requires addi onal data to be
    collected. This can be easier at the provider
    level, but more detailed informa on is
    needed to introduce such a mechanism for
    a specifi c CBG or at pa ent level. Again,
    strong informa on management systems

    will be needed. CBG payments have the
    poten al to incen vize this addi onal data
    collec on but monitoring and audi ng
    mechanisms must be in place to ensure
    data accuracy (23).

    An important ques on is how to pay
    for treatments based on technological
    innova ons that improve quality and how
    to induce their adop on. CBG payments
    will only encourage providers to adopt
    technological innova ons in treatment if
    these reduce the cost per case. However,
    if providers wish to adopt technological
    innova ons that have a benefi cial impact on
    treatment quality but are more costly than
    conven onal treatment, supplementary
    or separate payments or adjustments in
    the CBG system may be applied to cover
    the higher cost. If a CBG system is updated
    frequently, new diagnos c and treatment
    op ons can be refl ected through addi onal
    case groups or adjusted rela ve weights
    (30).

    44 HEALTH FINANCING GUIDANCE NO. 10

    adjus ng case classifi ca ons, crea ng new
    case groups, or removing groups if they are
    not appropriate. Clear rules help ensure
    transparency in the design and revision
    of the CBG system and avoid the process
    being taken over by interest groups.
    Most countries have created a “case mix
    centre” under the Ministry of Health or the
    purchasing agency, or as an independent
    agency, to be in charge of upda ng the
    classifi ca on algorithm. Thailand, for
    instance, has a case mix centre under the
    Ministry of Health which regularly proposes
    updates to the country’s DRG system (28).
    A case mix centre can also be involved in
    cos ng studies.

    If there is no rou ne data collec on process
    to generate informa on on changes in the
    average cost per case within a given group
    or changes in cost structure, regular cos ng
    studies will be needed. Given the me it
    takes to collect, compile and analyse data,
    most revisions of rela ve case weights are
    based on data which are between one and
    three years old (32).

    In most cases, pa ent classifi ca on systems
    are updated when necessary. Revisions in
    classifi ca on systems may include updates
    to the diagnosis classifi ca ons such as ICD-

    10 country-specifi c varia ons or procedure
    classifi ca ons. These changes must also be
    refl ected in the classifi ca on algorithms
    and grouper. Several CBG systems have a
    process of annual upda ng, such as those
    of Thailand or the Nordic Casemix Centre
    which maintains the classifi ca on system
    and algorithm used in several northern and
    eastern European countries. In the la er,
    member countries can submit proposals
    for the crea on, merging or removal of
    case groups (53).

    In general, there is pressure from providers
    to increase the number of groups over
    me and to introduce specifi c mechanisms

    to ensure that high-cost services are paid
    at higher rates. However, an increased
    number of case groups does not necessarily
    improve the CBG system. Indeed, a CBG
    system with many more case groups can be
    more diffi cult to manage, especially from
    a purchaser’s perspec ve, as verifi ca on
    of the right classifi ca on of cases tends to
    become more cumbersome. Consequently,
    various countries also remove case groups
    that are not used or may merge cases in
    order to reduce the number of overall case
    groups (5).

    Informa on to the general public
    should focus on the issues that aff ect
    pa ents. Pa ents must be informed
    about and understand their en tlements
    and obliga ons, including co-payment
    requirements, whether balance billing is
    allowed and which referral and gate-keeping
    rules apply. Pa ents who understand their
    rights and obliga ons can also contribute
    to checking provider compliance (e.g. they

    can report providers who engage in balance
    billing through complaints mechanisms
    where they are in place).

    Agencies in charge of CBG development
    might also invite public comments on dra
    documents which they make available on
    their website, as is the case in Australia and
    the United States. Publishing performance

    engagement by the general public (28).
    Purchasers can distribute informa on on
    the new payment method through exis ng
    channels, including websites, telephone
    hotlines, na onal and local media, as

    well as distribu ng informa on materials
    to providers and local authori es. The
    measures taken in Thailand to inform the
    public about the country’s health coverage
    scheme are described in Box 12.

    Box 12. Information provision to the public on the Universal Coverage Scheme, its
    benefits and payment system in Thailand

    In 2001, Thailand introduced the Universal Coverage Scheme (UCS), a health coverage
    scheme for all ci zens outside formal sector employment funded from general
    government revenues. The UCS introduced DRG payments for inpa ent care. The
    Na onal Health Security Offi ce (NHSO), in charge of opera ng the UCS, recognized the
    need for eff ec ve communica on with all stakeholders and used various channels to
    support smooth implementa on from the beginning.

    The launch of the UCS was publicized through the slogan “30 Baht treats all diseases”.
    “30 Baht” (less than US$ 1) refers to the co-payment per visit or per admission at health
    facili es, while “treats all diseases” describes the comprehensive benefi t package
    covering all diseases, except for a few treatments (e.g. an retroviral treatment, renal
    replacement therapy). The list of excluded health services was broadcast widely through
    mul ple channels such as television, radio, newspapers and the Internet.

    In parallel, providers at subdistrict level were required to register eligible members
    through a door-to-door census. These measures made the UCS widely known to eligible
    persons, health providers and the general public. Health facili es were further informed
    about the new payment method through workshops, mee ngs and offi cial instruc ons
    published in the Royal Thai Government Gaze e.

    Another measure was to ins tu onalize mechanisms for which health-care providers’
    and ci zens’ voices are heard and concerns are rec fi ed. For instance, the NHSO conducts
    technical hearings with providers before an upgraded DRG version is implemented. DRG
    manuals are published on the NHSO website and in paper. For providers, in addi on to
    an annual mee ng with health-care providers on opera onal details of the UCS, the
    NHSO also established a helpdesk reachable both by telephone and online to provide
    clarifi ca ons related to capita on and DRG payments. Benefi ciaries can reach the NHSO
    through a 24/7 call centre to obtain informa on on their benefi ts and rights under the
    UCS and to receive assistance to resolve confl icts with providers. Moreover, the NHSO
    collects feedback from providers and UCS members during annual public hearings, as
    mandated by law. Finally, broadcas ng of rights and en tlements linked to the benefi t
    package con nues through mul ple channels, including new pla orms such as YouTube,
    Facebook, Instagram and on the NHSO’s own mobile applica on.

    In sum, easily understandable messages, clear instruc ons, real- me support for both
    benefi ciaries and providers, as well as the use of mul ple communica on channels,
    were crucial for smooth implementa on of the UCS and for adop on and acceptance of
    the new payment methods.

    CONCLUDING REMARKS

    Using case-based groups for informa on
    and payment is one instrument for moving
    towards strategic purchasing. However, the
    eff ects of a CBG system strongly depend on
    the system’s design and how well it aligns
    with the overall health system.

    The following points must be considered
    throughout the processes of design, pilot,
    implementa on and monitoring:

    • Policy-makers and prac oners should
    cri cally refl ect whether the problems
    of health-system performance can be
    addressed with the envisaged payment
    reform – i.e. the introduc on and
    opera on of a CBG system.

    • When se ng the objec ves to be
    achieved by opera ng a CBG system, one
    must consider whether the proposed
    design of the CBG is appropriate for
    maximizing these objec ves or whether
    alterna ve design features may be more
    appropriate.

    • The introduc on and opera on of a CBG
    system should be part of a longer-term
    strategy with clear objec ves supported
    by an implementa on plan that includes
    intermediate steps, responsible bodies
    and melines.

    • A CBG system should be updated
    con nually to ensure that it fi ts the
    respec ve health system context.
    Administra ve measures – including
    control – need to be in place to address
    any expected undesirable eff ects of a
    CBG system.

    • There should be con nuing assessment
    of whether the key stakeholders – i.e.
    the Ministry of Health, the purchaser(s)
    and the providers – have the required
    capaci es and, if not, how these
    capaci es can be generated.

    • Policy-makers need to evaluate whether
    the proposed design of the CBG system
    is in line with the capacity of the health
    informa on management system.

    • Policy-makers and prac oners should
    ask whether supporters and opponents
    of the CBG have been iden fi ed and
    whether strategies have been developed
    to address any concerns.

    • Integrated people-centred care and the
    objec ves of universal health coverage
    must remain at the heart of the CBG, and
    any risk that the economic objec ves of
    purchasers and providers take priority
    over pa ents’ needs must be constantly
    mi gated.

    adjustment coeffi cient. A coeffi cient applied to the
    base payment rate to adjust payment for the cost
    of mee ng the health-service needs of diff erent
    popula on groups or legi mate cost diff erences
    related to specifi c provider characteris cs (e.g.
    being located in a rural or remote area or serving as
    a teaching facility).

    average length of stay. The average number of bed-
    days (inpa ent days) for each pa ent discharged
    from the hospital. The average length of stay can be
    calculated for an en re facility, a department, or a
    diagnosis-related group classifi ca on.

    balance billing. The prac ce of a health-care
    provider charging a pa ent for the diff erence
    between what the purchaser agrees to pay for the
    service and what the provider chooses to charge.

    base rate. The average payment rate paid by the
    purchaser to the provider per unit of service, bundle
    of services, or registered individual.

    bed-day. A day during which a pa ent stays overnight
    in a hospital. Also referred to as an inpa ent day or
    pa ent day.

    blended payment system. A payment system that
    combines elements of mul ple payment methods
    to maximize the benefi cial incen ves (and minimize
    the perverse incen ves) of each. Also called a
    mixed-model payment system.

    bundled service payments. The alloca on of a
    fi xed payment to a health-care provider to cover all
    services, tests and procedures grouped into a higher
    aggregated unit (e.g. a service package or hospital
    discharge) rather than payment for each individual
    service.

    capita on payment. A payment method in which
    all providers in the payment system are paid a
    predetermined fi xed rate in advance to provide a
    defi ned set of services to each individual enrolled
    with the provider for a fi xed period. Also called per
    capita provider payment.

    case-based payment. A hospital payment method
    that pays hospitals a fi xed amount per admission
    or discharge, depending on the pa ent and clinical
    characteris cs, which may include department of
    admission, diagnosis and other factors. The payment
    rate covers all tests, procedures and other services
    provided during the hospital stay. If the cases are
    grouped according to diagnosis, it is a case-based
    diagnosis-related group (DRG) payment method.

    case group. A group of hospital cases defi ned for a
    case-based hospital payment system that includes
    cases with similar clinical characteris cs and that
    require similar resources to diagnose and treat
    cases or complete a phase of case management.

    case group weight. A measure that refl ects the
    rela ve use of resources linked to a specifi c case
    group in comparison to the overall average for all
    case groups. It is calculated by dividing the average
    cost per case in a given case group by the global
    average cost per case. It refl ects the resource
    intensity of diagnosing and trea ng cases in the
    case group rela ve to the average (54).

    case mix. The average rela ve complexity and
    resource intensity of services required to diagnose
    and treat pa ents in a hospital due to diagnosis,
    disease severity and personal characteris cs such
    as age.

    classifi ca on algorithm/grouper. An algorithm that
    assigns hospital cases to groups with associated
    rela ve case weights to calculate case mix or fi nal
    payment rates for each case in a case-based hospital
    payment system. The grouper is o en accompanied
    by a computer program, grouper so ware, to run
    the algorithm automa cally.

    comorbidity. A condi on that is not related causally
    to a pa ent’s principal disease process but increases
    a pa ent’s total burden of illness (54). It is also
    refl ected through secondary diagnoses.

    cost. The value of resources (inputs), expressed in
    monetary terms, used to produce a good or service,
    carry out an ac vity, or achieve a goal.

    cost accoun ng methods. Methods that use
    accoun ng principles to classify and measure all
    costs incurred in producing a good or service, carry
    out an ac vity, or achieve a goal.

    cost item. An input, or resource, used by providers to
    deliver health services to which costs are a ached.
    Cost items include both capital and recurrent items.

    diagnosis-related group (DRG). A classifi ca on of
    hospital case types into groups that are clinically
    similar and are expected to have similar hospital
    resource use. The groupings are based on diagnoses
    and may also include procedures, age, sex and the
    presence of complica ons or comorbidi es. DRGs
    are an example of a system of case groups and
    rela ve case weights. See also case-based payment.

    fee-for-service provider payment. A payment
    method that pays providers for each individual
    service provided. Fees or tariff s are fi xed in advance

    global budget provider payment. A payment method
    that allocates a fi xed amount to a provider for a
    specifi ed period to cover aggregate expenditures to
    provide an agreed-upon set of services. The budget
    can be used fl exibly and is not ed to specifi c line

    budget or volume overruns will not be compensated
    (54).

    health purchaser. An en ty that transfers pooled
    health care resources to providers to pay for covered
    health-care goods, services and interven ons.
