NEW YORK — The health care discussion in the United States increasingly has revealed evidence of how corporations and politicians hinder the provision of adequate health care to the majority of Americans. The result is that the U.S. has one of the worst health care systems among industrialized nations.

Studies carried out by the World Health Organization and the Commonwealth Fund in New York show that overall performance of the U.S. health care system ranked 37th among the countries included in their analysis.

The Commonwealth Fund study, released in 2007, titled "Mirror, Mirror on the Wall: An International Update on the Comparative Performance of American Health Care," found that the U.S. health care system was not only the most expensive in the world, but it also came in last in most measures of performance.
