Do you have a link to that (those) studies?
Health care statistics can be tricky. What's a better hospital, the one that sees hundreds of deaths due to trauma every year or one that sees very few trauma related deaths? On the surface one hospital appears better than the other, right?
There is no way the Canadian health care system is better than the American health care system unless we lump in private and county hospitals for any statistic we arrive at. And if that's what we're doing then the comparison between the US and Canada cannot be made if we expect a meaningful result. Yes, more is spent on American health care per-capita, but some of that has to do with better and more costlier care being provided.
The CEO of Toronto's University Health Network, Robert Bell, said it best when he wrote to the Wall Street Journal several years ago in response to Michael Moore's movie Sicko.
In a letter to the Wall Street Journal, the President and CEO of University Health Network, Toronto, said that Michael Moore's film Sicko "exaggerated the performance of the Canadian health system — there is no doubt that too many patients still stay in our emergency departments waiting for admission to scarce hospital beds."
However, "Canadians spend about 55% of what Americans spend on health care and have longer life expectancy, and lower infant mortality rates. Many Americans have access to quality health care. All Canadians have access to similar care at a considerably lower cost." There is "no question" that the lower cost has come at the cost of "restriction of supply with sub-optimal access to services," said Bell.
Of course what Bell fails to mention is that life expectancy in the US and Canada are slightly different because of different lifestyles and other factors, but life expectancy is not necessarily the result of better or poorer care. And neither is infant mortality.
