Summary: Researchers determine whether patient-surgeon gender concordance is associated with mortality of patients after surgery in the United States. Study participants were 100% Medicare fee-for-service beneficiaries aged 65 to 99 years who had one of 14 major elective or nonelective (emergent or urgent) surgeries in 2016 to 2019.

Findings: Patient-surgeon gender concordance was associated with a slightly lower mortality for female patients, but a higher mortality for male patients for elective procedures, although the difference was small and not clinically meaningful. No evidence suggests that operative mortality differed by patient-surgeon gender concordance for nonelective procedures. Post-operative mortality rates were similar among the four types of patient-surgeon gender dyads.
