Hysterectomy Route and Numbers Reported by Graduating Residents in Obstetrics and Gynecology Training Programs.

Objective: To characterize trends in self-reported numbers and routes of hysterectomy for obstetrics and gynecology residents using the Accreditation Council for Graduate Medical Education (ACGME) case log database.

Methods: Hysterectomy case log data for obstetrics and gynecology residents completing training between 2002-2003 and 2017-2018 were abstracted from the ACGME database. Total numbers of hysterectomies and modes of approach (abdominal, laparoscopic, and vaginal) were compared using bivariate statistics, and trends over time were analyzed using simple linear regression.

Results: Hysterectomy data were collected from 18,982 obstetrics and gynecology residents in a median of 243 (interquartile range 241-246) ACGME-accredited programs. The number of graduating residents increased significantly over time (12.1/year, P<.001), whereas the number of residency programs decreased significantly (0.52 fewer programs per year, P<.001) over the 16-year period. For cases logged as "surgeon," the median number of abdominal hysterectomies decreased by 56.5% from 85 (interquartile range 69-102) to 37 (interquartile range 34-43) (P<.001). The median number of vaginal hysterectomies decreased by 35.5% from 31 (interquartile range 24-39) to 20 (interquartile range 17-25) (P=.002). The median total number of hysterectomies per resident decreased by 6.3% from 112 (interquartile range 97-132) to 105 (interquartile range 92-121) (P=.036). In contrast, the median number of laparoscopic hysterectomies increased by 115% from 20 (interquartile range 13-28) in 2008-2009 to 43 (interquartile range 32-56) in 2017-2018, despite the decrease in overall number of hysterectomies (P<.001). These trends were statistically significant.

Conclusions: The total number of hysterectomies performed by obstetrics and gynecology residents in the United States is decreasing, and the routes are changing with decreases in abdominal and vaginal approaches, and an increase in use of laparoscopic hysterectomy.
