Abstract
BACKGROUND: The health care marketplace has changed substantially since the last assessment of demand for internal medicine physicians in 1996. METHODS: We reviewed internal medicine employment advertisements published in 4 major medical journals between 1996 and 2004. The number of positions, specialty, and other practice characteristics (e.g., location) were collected from each advertisement. RESULTS: Four thousand two hundred twenty-four advertisements posted 4,992 positions. Of these positions, jobs in the Northeast (31% of positions) or single specialty groups (36.8% of positions) were most common. The relative proportion of advertisements for nephrologists declined (P <.001), while the relative proportions of advertisements for critical care specialists (0.5% in 1996 to 1.7% in 2004,P=0.004) and hospitalists (1.0% in 1996 to 12.1% in 2004,P<.001) increased. Advertisements for outpatient-based generalist positions (i.e., Primary Care and Internal Medicine) declined (−2.7% relative annual change, 95% confidence interval [95% Cl] −4.1%, −1.2%) between 1996 and 2004, a decrease largely due to a substantial decline in advertisements noted between 1996 and 1998. However, over the entire time period, the combined proportion of advertisements for all generalists (hospitalists and outpatient-based generalists) did not change (0.5% relative annual change, 95% Cl −0.8% to 2.0%). CONCLUSIONS: Since 1996, demand for the majority of medical subspecialties has remained constant while relative demand has decreased for primary care and increased for hospitalists and critical care. Increase in demand for generalist-trained hospitalists appears to have offset falling demand for outpatient generalists.
