After reading the commentary (see here )by Dr. Scott W. Atlas I would give that publication my vote as the worst or darn close to it. Dr. Atlas is a Senior Fellow at the Hoover Institution and is chief of neuroradiology at the Stanford University Medical Center and has a long list of scientific publications to his credit.
It is amazing how often sound bites from that study are quoted not only by the main stream media but also recited as gospel by medical researchers often in the boiler plate introductions to what otherwise would legitimately pass for a scientific publication.
How many times have we been told that something must be done about the U.S. health care system because although the U.S. spends 16 % of its GDP on health care it ranks 37th (out 191 countries) in something the WHO staffers called "overall performance".
Dr. Atlas said the the WHO publication " ranked countries according to their alignment with a specific political and economic ideal-socialized medicine-and then claimed it was an objective measure of "quality" ".
Quality,which is always a usefully ambiguous concept, was in the view of the report's authors the degree to which a country had distributed wealth and centralized administration of health care.
Atlas explains that 62.5 % of the overall performance index created by the report to rank countries was an assessment of one particular concept of equality and not about health care outcomes at all.
Quoting Dr. Atlas :
In fact, World Health Report 2000 was an intellectual fraud of historic consequence—a profoundly deceptive document that is only marginally a measure of health-care performance at all.
Read Dr. Atlas's commentary for more details of the methods used by the WHO staffers to achieve this propaganda masterpiece. I expect politicians and policy wonks with a particular agenda to quote the WHO's factoids but it is embarrassing to see medical researchers use the bogus material from the report as fillers and appropriately politically correct genuflexions to the notion of social justice in their publications.
