Through its Small Grants Program, the Fund supports efforts to learn from other countries' innovations. One of the 2004-05 grants supported international sessions at the 2004 AcademyHealth Annual Research Meeting, at which presentations were made on the Fund's International Working Group on Quality Indicators and OECD Quality Indicators project, lessons from abroad concerning the use of quality-improvement incentives, and results of the Fund's 2003 International Health Policy Survey of hospital executives. Small Grant support also enabled publication of the lead article in the May/June 2004 issue of Health Affairs, "U.S. Health Care Spending in an International Context," by Uwe E. Reinhardt, Peter S. Hussey, and Gerard F. Anderson. The study examined factors explaining high U.S. health care spending relative to other countries with much older populations, including disproportionately high administrative costs and the fragmented nature of the U.S. health system. Published in the same issue was an analysis of trends in international nurse migration, prepared by the University of Pennsylvania's Linda Aiken and colleagues.
