Patients aged 65 and older account for 39% of ambulatory visits to internal medicine physicians. This article describes the progress made in training internal medicine residents to care for older Americans. Program directors in internal medicine residency programs accredited by the Accreditation Council for Graduate Medical Education were surveyed in the spring of 2005. Findings from this survey were compared with those from a similar 2002 survey to determine whether any changes had occurred. A 60% response rate was achieved (n=235). In these 3-year residency training programs, 20 programs (9%) required less than 2 weeks of clinical instruction that was specifically structured to teach geriatric care principles, 48 (21%) at least 2 weeks but less than 4 weeks, 144 (62%) at least 4 weeks but less than 6 weeks, and 21 (9%) required 6 or more weeks. As in 2002, internal medicine residency programs continue to depend on nursing home facilities, geriatric preceptors in nongeriatric clinical ambulatory settings, and outpatient geriatric assessment centers for their geriatrics training. Training was most often offered in a block format. The mean number of physician faculty per residency program dedicated to teaching geriatric medicine was 3.5 full-time equivalents (FTEs) (range 0-50), compared with a mean of 2.2 FTE faculty in 2002 (P<or=.001). Internal medicine educators are continuing to improve the training of residents so that, as they become practicing physicians, they will have the knowledge and skills in geriatric medicine to care for older adults.
