Canada. They then compare the two nations using a "health utility index" and the percent of people with pain that limits their activities. For both of these, Canadians do better than Americans, until minorities are subtracted from the population. Finally, they compare the prevalence of chronic condition like diabetes, emphysema and arthritis in the two nations, and the proportion of people with each condition who are getting treatment. They conclude that while slightly more Americans are chronically ill, more of them are getting treatment. But millions of uninsured Americans with chronic illnesses like diabetes or high blood pressure are unaware of their diagnoses because they can't afford the doctors visit or lab test needed to make the diagnosis. Surveys will not identify undiagnosed persons as having chronic disease. Hence, the proportion getting treatment is falsely inflated in the U.S. Moreover, even the differences they cite to favor the U.S. are not statistically significant. Hence, a more accurate depiction of the data would state that among people who know of their diagnoses, rates of care are similar in the two nations. 3-More Americans get cancer screening and the U.S. has more high tech health resources than Canada For mammography, they include all women 40-69 in their calculation of screening rates. But neither the American College of Physicians nor the Canadian Task Force on Preventive Health Care recommend mammograms for all women 40-50. Mammograms for women in this age group leads to more breast surgery and other cancer treatments, but has not
