Does patient-surgeon gender concordance lead to lower patient mortality? Mostly no, UCLA-led research suggests

2023-11-23
Does patient-surgeon gender concordance lead to lower patient mortality? Mostly no, UCLA-led research suggests New research finds little evidence that post-surgical patient mortality is lower when patient and surgeon are the same gender. While gender concordance has been shown to improve patient care in other health specialties, evidence has been limited when it comes to concordance between patient and surgeon. This study shows that gender concordance was associated with lower mortality for female patients, but higher mortality for male patients—patient mortality was the lowest for ...
