To evaluate whether there are differences in several performance metrics between male and female surgeons for hysterectomies.

Multicenter retrospective cohort study. We matched surgeries performed by female surgeons to those by male surgeons using a propensity score and compared outcomes by gender after adjusting for years in practice and fellowship training.

6 hospitals (3 academic, 3 community) in Ontario, Canada between July 2016 and December 2019

All consecutive patients

Hysterectomy

Primary outcome was a composite of any complication or return to emergency room within 30 days. Secondary outcomes were Grade II or greater complications, return to emergency room, and operative time. We included 2664 hysterectomies performed by 77 surgeons. After propensity matching, 963 surgeries performed by females were compared to 963 performed by males. There were no differences in the primary (RR 0.92, 95% CI 0.71-1.20, p=.56) or secondary outcomes of Grade II or greater complication (RR 1.01, 95% CI 0.71-1.45, p=.96) or return to emergency room (RR 0.81, 95% CI 0.55-1.20, p=.30). Surgeries performed by males, however, were 24.72 minutes shorter (95% CI 18.09–31.34 minutes, p<.001). Entire cohort post-hoc regression analysis confirmed these findings. E-value analysis indicated that it is unlikely for an unmeasured confounder to undo the observed difference.

While complication and readmission rates are similar, male surgeons may have a shorter operating time than female surgeons for hysterectomies, which may have implications for health systems and inequalities in surgeon renumeration.
