National Study of Internal Medicine Manpower: XVI. Subspecialty fellowship programs, 1988 update.

Much of the debate about medical manpower during the 1980s has focused on the growing number of medical subspecialists. We examined the number of subspecialty fellows since 1976, paying particular attention to data collected in the 1987-1988 academic year. The number of fellows in subspecialty training at a given time has increased by 27% since 1976; however, much of this increase is due to the increased length of the training programs. The number of first-year fellows has increased only 7% since 1976. Growth in the number of fellowships has varied by subspecialty. The number of fellowships in geriatrics, critical care, and general internal medicine has increased dramatically. Additionally, the traditional subspecialties-cardiology, pulmonary disease, gastroenterology, infectious diseases, rheumatology, and allergy-immunology-have all grown to some extent. Program directors in all subspecialties anticipate continued growth in the coming years.
