Patients treated by female doctors have lower mortality rates compared to those treated by male physicians, according to a study published in the Annals of International Medicine. The study examined Medicare claims data from 2016 to 2019 for over 777,000 patients and found that the mortality rate for female patients was 8.15% when treated by female physicians versus 8.38% when the physician was male. While the difference for male patients was smaller, female physicians still had the edge with a 10.15% mortality rate compared with male doctors 10.23% rate.
