The study examined 104”‰630 patients who treated by 3,314 surgeons in Ontario, Canada, between 2007 and 2015. Of these surgeons 774 were women and 2,540 were men. The patients were matched by factors such as age, gender, comorbidity, surgeon volume, surgeon age, and hospital to patients undergoing the same operation by both male and female surgeons. After this matching, the results showed that fewer patients treated by female surgeons died, were readmitted to hospital, or had complications within 30 days.
Dr. Satkunasivam writes that “female and male physicians differ in their practice of medicine in ways that might substantially affect patient outcomes. These findings support the need for further examination of the surgical outcomes and mechanisms related to physicians and the underlying processes and patterns of care to improve mortality, complications, and readmissions for all patients.”
The author adds that the results “have important implications for supporting sex equality and diversity in a traditionally male dominated profession.”
