BACKGROUND: High rates of attrition have been documented nationally in assistant professor faculty of U.S. medical schools. Our objective was to investigate the association of individual level risk factors, track of academic appointment, and use of institutional leave policies with departure in junior faculty of a research-intensive school of medicine. METHODS: Participants included 901 faculty newly hired as assistant professors from July 1, 1999, through December 30, 2007, at the Perelman School of Medicine at the University of Pennsylvania. The faculty affairs database was used to determine demographics, hiring date, track of appointment, track changes, time to departure, and use of work-life policies for an extension of the probationary period for mandatory review, reduction in duties, and leave of absence. RESULTS: Over one quarter (26.7%) of faculty departed during follow-up. Faculty appointed on the clinician educator or research tracks were at increased risk of departure compared to the tenure track (hazard ratio HR 1.87, confidence interval, CI 1.28-2.71; HR 4.50, CI 2.91-6.96; respectively). Women appointed on the clinician educator track were at increased risk of departure compared to men (HR 1.46, CI 1.04-2.05). Faculty who took an extension of the probationary period were at decreased risk of departure (HR 0.36, CI 0.25-0.52). CONCLUSIONS: At this institution, junior faculty on the tenure track were least likely to depart before their mandatory review compared to faculty on the clinician educator or research tracks. Female assistant professors on the clinician educator track are of significant risk for departure. Taking advantage of the work-life policy for an extension of the probationary period protects against attrition.
