New Entrants and Choice of Medical Specialty

Almost 24,000 physicians complete their training through programs of graduate medical education (GME) each year. Before completing residencies and fellowships, new physicians must earn a four-year college degree and complete four years of medical education. Four out of five physicians completing GME are graduates of United States medical schools. Most are graduates of schools of allopathic medicine, which annually graduate approximately 15,000 to 16,000 MDs. This number has been relatively stable since 1980, and the baseline projections assume that the U.S. will continue to graduate approximately 16,000 MDs per year through 2020. Schools of osteopathic medicine graduate approximately 3,000 DOs per year, and the baseline supply projections assume that this number will steadily increase to approximately 4,000 per year over the next decade.

Over 5,000 IMGs are accepted into United States GME programs each year. An increasing percentage of IMGs are citizens or permanent residents (US IMG) who graduated from medical schools in other countries. Foreign IMGs under enter the United States for GME under the temporary work (H) or training (J) visa programs. Foreign IMGs with a J visa can participate in the J-1 Visa Waiver Program, which allows physicians to remain in the United States, if they agree to provide primary care services in federally-designated health professional shortage areas (HPSAs) for a minimum of three years after completing their residency. The PSM projects the number of IMGs who will remain in the United States based on historical patterns that vary by specialty.

The PSM models specialty choice based on the number of medical graduates entering different GME residency programs, historical trends of specialization as estimated through an analysis of the AMA Masterfile data, and data from the AAMC medical school Graduation Questionnaire. A more complete description of the specialty allocation is provided in other reports (e.g., Altarum, 2000). Specialty choice varies substantially by gender and by whether students are USMGs or IMGs. Among USMGs, for example, female physicians are three times more likely to become pediatricians than are male physicians.
