Comparisons of the U.S. health care system and those of other industrialized countries reveal striking differences in spending, availability and use of services, and health outcomes. This project will produce the ninth paper in an annual series of analyses of key health data for the 30 member nations of the Organization for Economic Cooperation and Development (OECD). The authors will provide an update of overall trends in health systems' performance, with an emphasis on health spending, coverage, hospital capacity and utilization, pharmaceutical costs, availability and use of technology, trends in health manpower supply and demand, and quality of care. Findings from the analysis will be submitted to the journal Health Affairs for Web publication and used by the Fund's Commission on a High Performance Health System. In addition, a chartpack featuring key data from the OECD database will be updated as a resource for journalists, policymakers, and researchers.
