Employment choices in conditions of physician oversupply: a study of graduates of San Francisco internal medicine programs, 1979-1984.

The authors surveyed 297 internists who completed residency or fellowship training at six San Francisco institutions from 1979 through 1984 to assess how the recent expanded supply of physicians has affected their intensity of practice and their decisions about location of practice. The vast majority of internists (93%) settled in metropolitan areas, with 56% remaining in the San Francisco Bay Area, despite that region's already high concentration of physicians. Mean annual income, in 1984 dollars, was slightly more than figures from national surveys of physicians of similar age ($72,560 vs. $71,900), but reported mean work week was shorter (54.8 hours vs. 60.5). Although subspecialists earned significantly more than generalists, this was because they worked more hours. Those who graduated later were significantly less likely to be in private practice in 1985, mainly because they initially selected salaried institutional work more often than earlier graduates (p less than 0.001). Women worked 85% of the men's work week and subspecialized significantly less often (p less than 0.05). These findings suggest that internists trained in already "over-doctored" areas will continue to settle there or in similar communities.
