Cusimano MC, Moineddin R, Chiu M, et al. - Between-surgeon variation in bilateral salpingo-oophorectomy was examined and surgeon and patient characteristics linked with bilateral salpingo-oophorectomy were investigated in order to evaluate current quality of care and determine targets for knowledge translation and future research. In this population-based retrospective cross-sectional study, they assessed 44,549 adult women ( > 20 years) undergoing benign abdominal hysterectomy. Of these women, 17,797 (39.9%) underwent concurrent bilateral salpingo-oophorectomy and 26,752 (60.1%) did not. Observations revealed marked between-surgeon variation in bilateral salpingo-oophorectomy rates. The variation was evident even after adjusting for patient case mix, indicating an ongoing uncertainty in practice.
