Please, let me elaborate a bit. It was my mistake when I made such a broad generalization I should have been specific and mentioned only Canada and the UK... But let me touch on a couple things the article says and correct it where it over-generalizes things.
Healthy lives: Where life expectancy is a decent metric to make a broad generalization, it's no where near the end all be all. Infant mortality is tracked in different ways in different countries. Abortions may or may not come into play here and skewer stats a bit especially when it considers "Potentially preventable" such language can't be taken as 100% truth
Access to care: True, people in 2011 had a harder time affording health care... except if you take into account how much people in Canada and the UK get taxed on health insurance and the numbers are more than comparable to the US. Also the ACAct made health insurance affordable for anyone and everyone to the point where it's now technically against the law to not have insurance and those who do not are subject to a tax. A lot of people get mad over this but for the wrong reasons which I can elaborate on if you'd like.
Health care Quality: Here it says the US ranks near the top, which it does. This article and study then goes on to say it does not provide safe or coordinated care, which is puzzling as it does not go into detail. This is something that has to go into detail especially when government sponsored health care facilities in places like Canada and the UK are notoriously slow and uncoordinated when compared to those in the US. A good video that compares: https://www.youtube.com/watch?v=q2jijuj1ysw
Efficiency: This point I will concede. The metric on which it measures and compares health care systems is right here "Low marks on time and dollars spent dealing with insurance administration" but as is the nature of dealing with a 3rd part insurance company. Ironically its this exact process that people condemn but don't understand that it's the reason why the US health care system is as good as it is (Video above explains a bit more)
Equity: Again, the same point made about spending and costs. This point, however is more irrelevant in today's world with Obama care and the ACA. Other countries simply do NOT include the taxed amount of spending that goes into health care when compared to the US. This publication is very disingenuous.
