title: Attrition rates between residents in obstetrics and gynecology and other clinical specialties, 2000-2009.
abstract: BACKGROUND
  As resident attrition disrupts educational and workload balance and reduces the number of graduating physicians to care for patients, an ongoing goal of graduate medical education programs is to retain residents.
  
  
  OBJECTIVE
  We compared annual rates of resident attrition in obstetrics and gynecology (Ob-Gyn) with other clinical specialties of similar or larger size during a recent 10-year period, and explored the reasons for resident attrition.
  
  
  METHODS
  In this observational study, we analyzed annual data from the American Medical Association Graduate Medical Education Census between academic years 2000 and 2009 for residents who entered Ob-Gyn and other core clinical specialties. Our primary outcome was the trend in averaged annual attrition rates.
  
  
  RESULTS
  The average annual attrition was 196 ± 12 (SD) residents, representing 4.2% ± 0.5% of all Ob-Gyn residents. Rates of attrition were consistently higher among men (5.3%) and international medical school graduates (7.6%). The annual rate of attrition was similar to that for other clinical specialties (mean: 4.0%; range: from 1.5% in emergency medicine to 7.9% in psychiatry). The attrition rates for Ob-Gyn residents were relatively stable for the 10-year period (range: 3.6% in 2008 to 5.1% in 2006). Common reasons for attrition were transition to another specialty (30.0%), withdrawal/dismissal (28.2%), transfer to another Ob-Gyn program (25.4%), and leave of absence (2.2%). These proportions remained fairly constant during this 10-year period.
  
  
  CONCLUSIONS
  The average annual attrition rate of residents in Ob-Gyn was 4.2%, comparable to most other core clinical specialties.
