Some Statistics On Health Care
Mark Thoma has been discussing health care a bit lately, including in
yesterday's post "Striking Health Care Fact?", in which he responds to
comments by Greg Mankiw and Tyler Cowan. Mark points out that the
"striking fact" noted by Cowan (namely, that doctor salaries in the US
are more than three times higher than salaries in France) accounts for
just a tiny fraction of the difference in health care costs between
the US and France, and that France actually has better health outcomes
than the US.
I thought I'd take this chance to flesh out Mark's assertion that
France's health care system keeps its people healthier than the
American health care system - because, in fact, it's not just France
that does better than the US. It turns out that every industrialized
country in the world does at least as well, if not better, than the US
when it comes to health care outcomes for its people.
Here is a renewed look at some data that I wrote about a couple of
years ago over at Angry Bear, directly comparing the performance of
the US health care system with those of other industrialized
countries.
First let's take a look at the very young. How well does the US health
care system take care of children and mothers? The following table
gives a few indicators:
Notes: Infant and child mortality rates from OECD for 2003; maternal
death rate from the WHO for the year 2000.
The US does worst, or tied for worst, in every measure. But what about
the elderly? The following table gives details about the length and
quality of life that senior citizens enjoy in various rich countries
around the world.
Note: Data from year 2001. Source: WHO.
Not only is the US's life expectancy at or near the bottom of the
industrialized world, but Americans spend more of their shorter lives
in poor health (as defined by the WHO).
The most striking thing about this data, however, is that Americans
spend nearly twice as much as people in other developed countries
spend on health care. Our closest competitor for health care costs is
Switzerland, which still spends just 65% of what the US spends per
capita. (Interestingly, Switzerland is also second to the US in terms
of how much health care spending is paid for privately.) And yet all
of these countries acheive health outcomes that are as good as or
better than the US: longer lives, fewer dead babies and children, and
more quality of life for their elderly. Compared dollar for dollar,
there's no contest. The productivity of the US health care system is
terrible compared to other developed countries.
Notes: All data for the year 2004 except for Japan and Belgium, which
are from 2003. Data from the OECD.
One last point: some have argued that the US's poor showing on all of
these measures is simply an artifact of demographic or other
differences between the US and other developed nations, and is not a
function of the US's health care system. But it's not obvious to me
that such demographic differences systematically fall on the side of
giving the US's health care system more health problems to overcome.
For example, the US has a higher rate of obesity; but it also has a
lower prevalence of other risky behaviors such as smoking, driving
without seatbelts, etc.. The US has more people living in poverty due
to relatively high income inequality, but has higher overall and
average levels of income than most countries.
At any rate, it turns out that this is exactly the type of question
that econometric techniques were designed to answer. And the evidence
seems to suggest that the US's relatively poor health outcomes
(especially when considered relative to the vast spending that the US
does on its health care) are not the result of such demographic-type
factors.
One example is given in a 2003 OECD Working Paper titled "The US
Health System: An Assessment and Prospective Directions for Reform,"
by Elizabeth Docteur, Hannes Suppanz and Jaejoon Woo. They test the
influence that various demographic indicators (e.g. income per capita,
fertility, education levels, and income distribution) have on infant
mortality and life expectancy statistics in a panel of OECD countries.
Then they use those results to estimate how much of the US's poor
results simply reflect these demographic characteristics, and how much
are unexplained.
They find that such demographic factors do not explain any of the US's
bad health statistics. On the other hand, the US's low level of
publicly provided health care does explain about one-third of the US's
low life expectancy. The conclusion is that there is something
idiosyncratic about the US health care system (with some suggestive
evidence that the system's poor productivity is related to low public
funding) that yields relatively poor outcomes despite its enormous
costs.
In short: the average American receives mediocre-to-bad health care
outcomes while paying twice as much as citizens of the rest of the
