the U.S. -- about 30,000 excess deaths annually. It is far from clear that the greater use of CT scanners in the U.S. (relative to Canada) causes more good than harm. 4-Waits for care compromise access in Canada, and these access problems are worse than those in the U.S. The O'Neill analysis admits that fewer Canadians than Americans report an unmet health need (11.3% vs. 14.4%). In the U.S., cost is the big problem, while waits for care are more prominent in Canada. They try to obfuscate the Canadian advantage on access measures by presenting a complex sub-group analysis of pain suffered by those unable to get care. But when you cut through their obfuscation, even this measure favors Canada; about 12% more Americans who say they're unable to get care report being in pain. The O'Neills claim that mortality rates for lung, breast, colon and prostate cancers are lower in the U.S. than in Canada. They calculate mortality rates by dividing cancer deaths by the number of cases of cancer. When cancer death rates are calculated in a more standard fashion, i.e. the number of deaths per thousand people in the population, age adjusted cancer mortality is actually lower in Canada than in the U.S. for all of these cancers except colorectal cancer. But there are more cancers diagnosed in the U.S. Hence, the death rate among those who are diagnosed -- the figure the O'Neills choose as the most important - is lower in the U.S. This higher
