These days, fewer Americans are buying the claim that the United States has the best medical system in the world. Consumers are buying lower-cost online drugs from foreign sources, and some even become medical tourists" to obtain affordable treatment in other countries. Studies show Americans aren't healthier, nor are they living longer than people in industrialized nations that spend half per capita of what we do on care. A 2007 ... study that compared the United States with five other nations -- Australia, Canada, Germany, New Zealand and the United Kingdom -- ranked the U.S. health system last. And a 2000 report by the World Health Organization ... put the United States 37th out of 190 nations in health care services -- between Costa Rica and Slovenia. France was rated No. 1. In a New York Times/CBS poll conducted in March, health care ranked as the top domestic concern. We spend far more, but our health care is falling behind, studies say. "We, unlike any other country, have 46 million people who are uninsured, and that raises a whole host of health and financial issues," said Ken Thorpe, professor of health policy at Emory University. "Ours is really is a sick-care system." Thorpe said. He argues ... that it is far more cost-effective to prevent people from getting sick or at least catch illnesses early through better monitoring. Karen Davis, president of .... a nonprofit foundation that supports health care research said, "We tend to have more medical errors than other countries, in part because of this highly specialized, fragmented system. More things can go wrong and do go wrong."
