OMG.... I'm not sure if you are just trolling or really know nothing about the evaluation of healthcare systems...
how else are you supposed to measure the effectiveness of healthcare systems?
The WHO rankings are not as an objective as reports have led the general public to believe. In terms of how the WHO arrived at their statistics, there are some factors that make sense and demonstrate objectivity, while others do anything but.
Health Level (25% of total score) does demonstrate such objectivity, however it fails to address factors that are not indicative of the success (or failure) of a particular health care system, such as homicide, poverty, diet, smoking, exercise, etc. To assume that these factors do not significantly contribute to life expectancy is to truly let logic pass one by. Regardless, the health level index proves to be the most objective of the bunch, along with Responsiveness (12.5%), which is not as difficult to measure.
Next we have Financial Fairness. This score (worth a 25% of the final ranking) is determined basically by seeing what percentage of total income a household spends on healthcare, and then comparing averages across particular economic subsets of the population to determine this so-called fairness. Obviously, poorer households will spend a larger percentage of total income on healthcare. That said, they will also spend a larger percentage of their total income on other items as well (food, housing, etc). The financial fairness score is based on the ideology that that those in the population with higher incomes should carry more of the financial burden of healthcare. (Should we extend this ideology to other factors such as food and housing? Sounds a bit "Red" to me...)
The WHO Financial Fairness factor awards the nation whose government flips more of the health care bill (that is, by having those households with higher income burden the cost; in other words, the more socialized systems receive higher scores). This obvious lack of objectivity is based on a particular value judgement. Whether you agree with this judgement or not, you cannot claim objectivity. That's a huge issue when these rankings are stated as concrete statistical results- results that many within the general public take at face value without knowledge of the methods used to determine the final outcomes. Now this does not mean that determining how much our poor are spending on healthcare is not important or should not be taken into consideration to some degree. However, its use in these rankings is highly debatable, due to the lack of objectivity and reliance on a particular ideology (clearly based on a socialistic stance ), especially when the rankings are presented as objective data.
Next we have the Health Distribution (25%) and Responsiveness Distribution (12.5%) which are, again, measures of inequality- neither of which are a measurement of healthcare outcomes; they are instead measures of the differences in quality of care across population subsets. The larger the difference between the lowest quality and the highest quality of care, the lower the score. The country that provides lower quality across the board (hence demonstrating a higher degree of equality) could receive a higher score than that of another whose population with higher incomes receive better quality of healthcare than that of it's poorer populations, even if the level of quality received by that poorer population is equivalent to that of the first country mentioned. So, again, we see the use of ideology to determine significant portions of the WHO rankings, this ideology being that all citizens should have access to the same quality of healthcare, regardless of income or the possibility that those with more income may be more likely to spend more on healthcare. (Again, I'll ask: should this ideology be extended to things such as food, rent, etc?) Regardless, of one's political ideology, one can, again, do anything but claim that these statistics are exclusively objective.
The above are just some of the issues of the WHO rankings. Others such as how the information was collected and compiled via random sampling (with high uncertainty percentages) or the use of OP (overall performance) vs OA (overall attainment) rankings prove to be problematic, as well as how those results were calculated. (When people quote WHO rankings they are often using the OP not the OA, which does change up the rankings quite a bit. The determination of OP is a tweaking of OA via formulas, and the methods used to derive this number are debatable). Point being, utilizing the WHO rankings for the purposes of determining how effective our healthcare system proves to be is not as straight forward as many would like it to be. (e.g. Stating that the US spends so much per person but with lower life expectancy is quite misleading without a clear explanation of the methods use to determine such 'statistics;' manipulating stats in one's favor is nothing new and something we should all be well aware of). The methods used to arrive at these rankings lack objectivity; their inclusion of a political ideology (that many do not share) tarnishes its reliability, unless of course, one shares a similar ideology and wishes to use its results to push an agenda.
All of this said, I do not think anyone truly feels that things can continue as is. The status quo does not suffice. As someone mentioned earlier, Americans are some of the most innovative people since the dawn of the man, and we will arrive at our own solution. While the WHO rankings may help highlight some areas where improvement is necessary, its current methods are flawed, lack objectivity, and are not capable of determining how effective our current system is relative to that of the rest of the world.
