Comparison of postoperative outcomes among patients treated by male and female surgeons

摘要

Study question Do postoperative outcomes for patients undergoing common procedures differ between those treated by male and female surgeons? Methods This population based, retrospective, matched cohort study identified all patients who had one of 25 common surgical procedures in Ontario, Canada, from 2007 to 2015. Patients treated by a female surgeon were matched to patients who had the same operation by a male surgeon based on patient age, sex, and comorbidity; surgeon volume and age; and hospital. The primary outcome was a composite of death, readmission, or complications. Generalised estimating equations were used to compare outcomes between groups.
