On
June 24, 2000, the WHO released a report that assessed the world's
health-care systems based on an overall index of performance.1 The
report had an immediate and enormous impact and was discussed on the
front page of almost every major newspaper in the western world and on
the broadcast news. The WHO, the health agency of the United Nations
(UN), had assessed health-care systems around the world and everyone
wanted to know where his or her country was placed in the health-care
system league.
In health-policy circles, the report caused
some big surprises. At the top of the WHO's health-care league were
countries such as Spain and Italy, whose health-care systems were
rarely considered models of efficiency or effectiveness before. In
Spain, for example, release of the WHO report, which ranked the Spanish
system as the third best in Europe, after Italy and France, coincided
with unprecedented demonstrations against the Spanish health-care
authorities. Demonstrators were protesting against the long waiting
lists for critical life-and-death interventions (which had been
responsible for a large number of deaths) and the short consultation
times in primary-care centres (an average of 3 mins per consultation).
This state of affairs in the Spanish system had forced prominent
professional associations, including the Spanish Association of Primary
Care Physicians, to denounce the current situation as "intolerable"
(these events were widely reported in the Spanish press in June and
July; see, for example, the series in El Pais in June 2000). The
growing popular protest had put Spain's Conservative government on the
defensive, until the WHO brought out its report listing the Spanish
system as the third best in Europe and the seventh best in the world.
Spain's Conservative Minister of Health showed the WHO report to the
protesters as proof of the unjustified nature of their complaints and
demands.
The protesters, however, were not impressed by the
WHO's ranking of Spain's health-care system. Something seemed
profoundly wrong in the report's claiming that the performance of the
Spanish system was the seventh best in the world. The report's
conclusions certainly did not coincide with the perceptions of most
Spanish people. In one of the most rigorous surveys of views of the
Spanish population regarding health care, Spaniards expressed more
discontent with their system than did the population of any other major
country in the European Union, except Italy, whose health care was also
listed among the "best" in the WHO report. An impressive 28% of the
Spanish population (and an even more impressive 40% of the Italian
population) indicated "there was so much wrong with their HCS
(health-care system) that they needed to completely rebuild it", and an
additional 49% of the Spanish population (and 46% of the Italian
population) stated that "there were some good things in their HCS but
fundamental changes were needed to make it better."2 There was indeed a
disagreement about the definition of performance by the WHO and by the
Spanish and Italian populations. Who is right? In order to answer this
question, we must first understand that the WHO is not a scientific but
rather a political institution whose positions and reports must be
assessed both scientifically and politically.
The objective of the WHO ranking
Why
do we need to rank countries according to the performance of their
health services? Presumably, an important objective is to see what we
can learn from "the best", using them as points of reference on the
road to better health. A very important element in the WHO ranking,
however, is the credibility of the indicators of performance that it
uses. It is therefore important to know how the ranking was developed,
the assumptions behind the preparation of the indicators used in the
ranking, and the consequences for health policy of choosing one
indicator versus another.
Let us start with the nature of the
indicators. The WHO report develops three types of indicators. The
first is related to the effectiveness of the health-care system (mainly
medical care plus traditional public-health services) in reducing
mortality and morbidity. The second is related to the responsiveness of
the system to the user, understanding responsiveness as the ability to
protect the user's dignity; to provide confidentiality and autonomy; to
provide care promptly with high-quality amenities; to provide access to
social support; and to ensure a choice of provider. And the third type
of indicator is related to the fairness of the system, measured by the
degree of progressiveness in the funding of health care.
All
three types of indicators are weighted and added to create a single
indicator, the indicator of performance. It is unclear why the WHO felt
the need to come up with one synthetic indicator of performance. There
is not, after all, a single UN indicator for ranking countries by
economic performance. Rather, the annual UN economic reports use
specific indicators to measure different components of economic
efficiency such as unemployment, economic growth per capita, rate of
productivity growth, and so on. But no single indicator summarises the
many dimensions of the equally complex issue of economic performance.
So why did the WHO decide to make a single indicator for performance of
health-care systems? The WHO report is silent on this point.
Effectiveness of health-care systems
In
the WHO's conceptualisation of medical-care effectiveness, the report
uncritically reproduces a major assumption in medical-care cultures
that medicine is very effective in reducing mortality and morbidity. I
find it astonishing that a prominent public-health agency could state:
"The
differing degrees of efficiency with which health systems organize and
finance themselves, and react to the needs of their populations explain
much of the widening gap in death rates between the rich and poor, in
countries and between countries, around the world".
No evidence is
given for such a statement. Actually, published literature shows that
much of the widening gap in mortality rates within and among countries
is primarily related to the growing differentials in wealth and
income.3
"Health systems have played a part in the dramatic rise in life expectancy that occurred during the XX century".
Here
again, no scientific data are given to support such a statement.
Actually, the evidence shows that the most dramatic declines in
mortality and increases in life expectancy occurred during the 20th
century before medical care proved effective. Indeed, most dramatic
changes in mortality during the century were the result of social and
economic interventions.4.5
"If Sweden enjoys better health
than Uganda--life expectancy is almost exactly twice as long--it is in
large part because it spends exactly 35 times as much per capita in its
health systems".
Again, no evidence is given for this
statement. All the scientific data show there is no link between the
level of expenditures in health-care systems and level of mortality.
There is evidence, however, for a link between political interventions,
wealth and income distribution, and mortality indicators.6
This
enormous faith in the effectiveness of medical care reaches extreme
proportions when the WHO report indicates that with "an investment in
health care of $12 per person, one third of the disease burden in the
world in 1990 would have been averted". Thus, the report gives the
impression that the major problems of mortality and morbidity are a
consequence of the limited resources of health-care systems. Give more
money to a health system and more lives will be saved. The report even
quantifies how many lives could be saved per dollar invested. Very
neat, but profoundly wrong. Nowhere does the WHO report present any
scientific evidence to support these wild assertions. Again, most
available data show that other factors are far more important in
explaining a country's level of health and mortality than are its
medical services. Any student of public health knows that medicine is
not as effective in reducing mortality and morbidity as the medical
establishment believes. Indeed, there is extensive literature on the
social, cultural, economic, and political causes of health and disease.
That medical care is less effective in reducing mortality than the WHO
report assumes does not mean, of course, that medicine is not useful in
taking care of patients' medical conditions and improving their quality
of life. But it is wrong to explain a country's level of mortality by
its medical services. Not even public-health interventions (such as
immunising against childhood diseases), which have been far more
effective in reducing mortality than have medical-care interventions,
can be considered the main reasons for the mortality decline in the
20th century. Social, economic, and political interventions are the
primary reasons for this decline.
This mistaken
assumption--overestimating the effectiveness of medical and health
care--explains why some countries, such as the Mediterranean countries,
Spain, Italy, Portugal, and Greece, which traditionally have good
health indicators with long life expectancies, earn high marks in the
WHO's classification of effectiveness. The report erroneously
attributes the low mortality in these countries to the effectiveness of
their medical care. Actually, these various Mediterranean countries
have different types of health services, but all share the
characteristic that public expenditures in the health-care system as a
percentage of gross national product are among the lowest in the EU.
Table 2 (basic indicators for all member states) of the WHO report
shows these are among the countries with the lowest probability of
dying (per 1000) for children under 5 years and for adults between 15
and 59 years, and with the longest life expectancy in the world. None
of them have large health-system expenditures. Their types of funding
and organisation are extremely varied--with the common denominator,
however, of the populations' high level of dissatisfaction with their
health systems. Actually, the WHO report lists these health systems as
among the least responsive (to users) of all European systems. In the
ranking for responsiveness, Spain is listed 34th, Greece 36th, Portugal
38th, and Italy 23rd, all of them among the least responsive in the EU.
It would seem then, according to the authors of the WHO report, that
the effectiveness of health-care systems in reducing mortality
outweighs their limited responsiveness. They are thus considered
user-unfriendly but very effective nevertheless. It is highly
questionable, however, whether the good mortality indicators of these
countries are the results of health-care system interventions.
Who defines the indicators of responsiveness?
The
second component of performance is related to what the report called
"responsiveness" of the health-care system to users. The report
includes here two major groups of considerations. The first deals with
what the report calls "respect for persons", which includes the dignity
afforded to the patient, the confidentiality of patients' information,
and patients' autonomy. The second group is referred to as
"client-oriented attributes", such as prompt attention to the patient,
the quality of the amenities, access to social support networks, and
choice of provider. It would seem that these characteristics should
give a fairly good idea of how responsive a health-care system is to
its users.
Conceptually, then, indicators of
responsiveness seem to be reasonable. The problem arises when we see
that the people who defined the values of these indicators and the
weights given to each (derived from questionnaires) are what the WHO
report calls "key informants", without specifying who those key
informants are. These unknown key informants are most likely experts on
health care in the various countries. And the survey of these
informants is therefore likely to be a survey of the "conventional
wisdom" among experts who define the degree of responsiveness of
health-care systems to users. The report does not explain who these key
informants are, nor does it explain the criteria for their selection.
It is likely, however, that the choice of these informants and experts
was highly biased towards what are called health-care-establishment
figures. Indeed, the selection of references in the report's
bibliography is quite biased and prejudiced against critical positions,
issues, or authors. One can find consistent references to conservative
and neoliberal authors (such as Alain Enthoven of Stanford University,
USA) and mainstream medical journals, but never does the report make
reference to critical authors or scientific journals that question
established wisdom.
Not surprisingly, therefore, the survey of
responsiveness reveals that the countries with more responsive
health-care systems are those whose health policies better fit what has
become the new conventional wisdom. In this thinking, health-care
services that combine public funding with public provision of health
care (which has characterised national health services) are out. They
are constantly referred to as examples of "heavy handed state
intervention . . . the type of intervention discredited everywhere",
"highly impersonal and inhuman (as in the pre-1990 Soviet Union)", and
"monolithic". The abusive nature of the disqualification of these types
of health services is all too clear when the collapse of the Soviet
Union is used as an example of the deficiencies of national health
services. The fashionable thing now, in current conventional thinking,
is an insurance system with a public-private mix that allows for
competition between managed care plans, giving patients--referred to as
clients--increased choice of providers and permitting more flexibility.
The WHO report presents the Thatcher reforms in the British national
health service as worth extrapolating to other systems. We should not
be surprised that these key informants and experts selected the USA as
having the system that is most responsive to users, and Colombia, a
Latin American country whose national health service has been replaced
by an insurance-based managed care competition model, as having the
most responsive system in Latin America.
This profoundly
ideological position of the WHO report also comes across in its
analysis of what the WHO considers the "failure" of the Alma-Ata
approach. The Alma-Ata Declaration was a famous WHO report, written in
1978, which emphasised the importance of primary-care services,
combining medical with social interventions at the primary level of
care. The new WHO report assumes that implementation of the Alma-Ata
report failed because, in designing such primary-care models, too much
attention was given to the health needs of the population and not
enough to the demand for services; the Alma-Ata report was too
oblivious to the importance of the private sector and the market.
According to the WHO's June, 2000, report, countries should give far
more importance to reforms that aim at "making money follow the
patient, shifting away from simply giving providers budgets, which in
turn are often determined by supposed needs", as many countries are now
doing. The report also indicates that there is a link (nowhere
documented) between expansion of private delivery of services and
responsiveness of the health-care system. This shift from planning
according to need toward demand in the market is a radical change in
WHO policy, a change I consider antagonistic to the basic principles of
public health.
Not surprisingly, besides choosing the USA
as the country with the most responsive system, the WHO report
considers the greatest challenge facing government-based health systems
is to respond to the need for regulating the private sector, a
function, say the authors, that most countries are not prepared for.
The model they advocate is that put forward by Enthoven (an author
cited approvingly in the report), which inspired the Thatcher reforms
in the British national health service.
Consequently, given
the political and propagandistic character of the report, nowhere do we
find quoted, cited, or argued the huge amount of scientific evidence
that questions each of the assumptions made in the report and
challenges the superiority of insurance-based health-care systems.
(There is an extensive literature critical of insurance-based managed
care, mostly published in the International Journal of Health Services
in the 1990s). To make the USA the top-ranked country in responsiveness
to health-care users not only ignores the large body of scientific
evidence that shows just how unresponsive the US health service
actually is, but also sets aside any observation of the political
context of health policy in the USA. The Democratic Party is now trying
to identify managed care and managed competition, and their
unresponsiveness to users, with the Republican Party as a way of
gaining some political advantage in the coming Presidential and
Congressional elections, knowing how unpopular managed care and managed
competition are with most citizens of the USA.
Unfortunately,
however, the WHO is doing what its American branch, the Pan-American
Health Organisation (PAHO), has been doing for years--functioning as a
transmission bell for Latin America of the conventional wisdom in US
financial and political circles. In recent years we have been
witnessing how the PAHO and now the WHO, with the assistance of the
World Bank and private foundations, are presenting insurance-based
managed care as part of the solution to the burgeoning health-care
problems in Latin America.7 The privately managed health-insurance
schemes are seen as playing a positive role in complementing and
competing with the government health-care systems. In a recent speech
to corporate and academic leaders in the USA, the Director General of
the PAHO referred to the successful experience of several private
health insurance schemes in Latin America, taking Instituciones de
Salud Previsional (ISAPRES), the major private insurance scheme in
Chile, as an example: "The example of ISAPRES in Chile shows the
possible success of the privately managed health and social insurance
schemes
