Among the 1,165,711 patients studied, 151,054 were treated by a female and 1,014,657 by a male surgeon. Overall, 14.3 percent of the patients had one or more adverse postoperative outcomes within 90 days and 25.0 percent had one or more adverse postoperative outcomes within one year following surgery. Among those who had adverse postoperative outcomes, 2.0 percent of patients died within 90 days and 4.3 percent died within 1 year. In all measures, patients with a woman surgeon were more likely to avoid negative outcomes. Overall, 2.4 percent of all patients who had been operated on by a man died within one year after surgery, compared to 1.6 percent of patients who had a woman surgeon.
The authors conclude that “after accounting for patient, procedure, surgeon, anesthesiologist, and hospital characteristics, the findings of this cohort study suggest that patients treated by female surgeons have lower rates of adverse postoperative outcomes including death at 90 days and 1 year after surgery compared with those treated by male surgeons.”
