Despite recent gains in establishing academic sections, divisions, and departments of geriatrics in medical schools, much remains to be done to meet the medical needs of an aging population. To better understand how medical schools are educating students in geriatric-related topics, all U.S. allopathic and osteopathic medical schools were surveyed in two waves, in 1999 and 2000, using a questionnaire based on recommendations from the Education Committee of the American Geriatrics Society. Responding schools were more likely to address diseases and conditions of aging, psychosocial issues, and ethical issues and less likely to cover anatomic changes, nutrition, knowledge of healthcare financing, outcome measurement, and cultural aspects of aging. Although limited, the results indicate that medical schools have increased coverage of aging-related material, although further expansion of geriatric content will be necessary to meet the needs of an aging society.
