A new study by researchers at the UCLA Fielding School of Public Health and McGill University in Montreal reveals that the United States health care system ranks 22 out of 27 high-income nations when analyzed for its efficiency of turning dollars spent into extending lives. The study, which appears online December 12 in the “First Look” section of the American Journal of Public Health, illuminates stark differences in countries' efficiency of spending on health care, and the U.S.'s inferior ranking reflects a high price paid and a low return on investment.
