Just a few points to address with regards to this topic.
Demographics: Canada - pop 30337334, life expectancy: Male 75.3, female 81.3, infant morttality rate 5.7, per capita GDP: 25000, total health expenditures as % GDP 9.3%, public % of total health expenditures 66.7%, per captia total health expenditures $2095
The US - pop 267 954 764, l.e. male 72.8, female 79.5, infant mortality rate 6.55, per captita GDP 26600, total health expenditures as %GDP 14.0%, public % of total health expenditures 46.7%, per captial total helath expenditures $4090.
Just to illustrate - life expentancy and infant mortality are two of the most important markers of “health at a glance”. Now even tho’ Canada spends a much smaller percent of its GDP on health than America, all of its citizens as more than adequate insurance (covering nearly everything except elective plastic surgery and experimental/very new drugs), America has around 45 000 000 citizens without ANY health insurance, and another 44-45 000 000 citizens with inadequante health insurance (i.e. will not cover the entire hospital stay in many cases, etc.).
What does this mean? Well, Canada spends less public money on health (and yet health is covered over 66% by public money) where the US spends more public money on health (covering much less, i.e. 46.7% - the rest from private sources), and we have approximately half the per capita expenditures on health than the States, and yet our primary health markers are at least equal to those of the Americans.
Furthermore, Canadian Physicians (and nurses) are better trained than Americans (as evidenced by our performance on the American Board exams) and are regularly woo’d by many states.
When you have a system as efficient and proficient at health, somethings are going to suffer. Canadian physicians do not get paid nearly as much as Americans, so many of them pour across the border. Furthermore when you spend less, you have fewer toys (MRI’s, CT scans, etc.) and nurses so patients, rather than wait, will go south where they may pay for diagnostic (and elective) proceedures to have them done more quickly. In Canada it is impossible (in most practical respects) to pay for medical care aside from pharmaceuticals, and plastic surgery (not including physiotherapy, chiropractic etc.). So in effect, we have a 2-tier system due to our proximity to the states - those who wish to pay for a proceedure simply cross the border. All others stay here, and get things done for free - more slowly, however generally by the most competant physicians in the English speaking world.
note; i did not include British, Japanese or Australian figures, although i do have them - too much typing.
