National health care expenditures, usually expressed per
capita, do not correlate in a linear fashion with health care outcomes; if they
did, the United States would be at the top. We are first in per capita
expenditures but rank 37th in health care outcomes among the 191 countries the
World Health Organization tracks in its surveys. I got curious about these
rankings. How are they calculated?
I discovered that the rankings everywhere quoted derive from
WHO’s World Health Report for 2000, which is based on 1997 data. Many of the
basic statistics of which that ranking was built have been updated in
subsequent WHO annual reports—but have not been combined to yield an updated
world ranking. What we are looking at, therefore are ranks obtained fifteen
years ago.
These rankings were built up by measuring five basic
indicators. These were (1) life expectancy, usually rendered as DALE for “disability-adjusted
life expectancy”; (2) the distribution of DALE across age groups, which was
measured by looking child survival; (3) responsiveness of the health care system
to the needs of the population and (4) the distribution of this response,
measuring the degree to which it reached the whole population equally; and (5)
fairness of financial contribution. WHO’s definition of fairness is that all
households’ out-of pocket expenditures will be roughly the same, measured as a
percentage of income exceeding what is needed for subsistence. This implies a
subsidized health system.
The five categories shown were labeled the “goals” of the
health system: high life expectancy and low infant mortality, a responsive
system that reaches all inhabitants in equal measure, and a fair apportionment
of total costs based on ability to pay. Data on health expenditures per capita were
finally added. Then, with uniform weights applied to each category to indicate
relative importance, an Overall Health System Performance rank was calculated.
In 1997 the United States ranked first in responsiveness and
in per capita expenditures on health care. It was 24th in life expectancy, 32nd
in “distribution” of life expectancy, thus infant mortality, third in the “distribution”
of responsiveness, 55th in fairness of financial contribution, and 37th
overall. A tabulation of the best and worst follows. The original WHO data may
be viewed here. Annex Table 1 contains a summation.
