Does a patient’s chances of serious outcomes differ if they are treated by a female doctor? A recent study looks into this hypothesis to ascertain the difference between chances of a patient dying under a male and a female doctor. According to the study, hospitalised patients treated by female doctors have a lower risk of dying within 30 days. They are also less likely to be re-hospitalised than those treated by male doctors. The study is published in JAMA Network Open."Past research has largely focused on surgical patients and the admitting physician only. Our findings add to the growing body of research examining the relationship between physician sex and patient outcomes, broadening the evidence beyond surgical care to a wider range of medical conditions and other physicians," says Dr. Angela Jerath, an ICES scientist, and Associate Professor, Department of Anesthesiology & Pain Medicine at the University of Toronto's Temerty Faculty of Medicine. After analysing the health records of 958,150 adults admitted to hospitals in Ontario, Canada, between 2008 and 2022, researchers found that the 30-day mortality rate was 12.3% among patients treated by female physicians, compared to 13.7% among those treated by male physicians.The findings also show a small difference in hospital readmissions. The 30-day readmission rate was 18.6% for patients treated by female doctors and 18.9% for those treated by male doctors.The researchers examined outcomes across seven common medical conditions, including heart attacks, pneumonia and other acute illnesses. They also considered the number of hospital days during which patients received care from female doctors, recognising that several doctors may be involved in a patient's treatment during an admission.Patients Treated By Female Doctors Are Less Likely To Die In A 30-Day PeriodAlso read: Manosphere Is A Public Health Concern: Lancet Report Says Online Misogyny Harms Men's Mental Health After accounting for patient, physician and hospital characteristics, treatment by a female physician was linked with 12% lower adjusted odds of death within 30 days compared to treatment by a male physician.The researchers also found that for every 10% increase in the proportion of hospital days managed by female physicians, the adjusted odds of 30-day mortality decreased by 7%. This was observed for most medical conditions that were studied. Atrial fibrillation was the only exception.The difference in mortality was also seen at longer follow-up periods. Patients treated by female physicians had lower mortality at 90 days and one year.The findings were observed among both male and female patients. Female patients treated by female physicians had the lowest adjusted 30-day mortality rate in the analysis.Why Patients May Have Better Outcomes With Female Doctors? The study did not establish why patients treated by female physicians experienced better outcomes. However, the researchers discussed possible differences in clinical practice and communication.Female physicians may be more likely to engage in patient-focused communication, spend more time with patients, follow clinical guidelines and involve colleagues in decision-making.These practices could influence how symptoms are studied, treatment decisions are made and coordinated during hospitalisation."The goal is not to favour one group of physicians over another but to identify practices and behaviours that may help improve care across the health system," says Jerath. "An important strength of this study is that, unlike surgical care, patients admitted to hospital for medical conditions are generally assigned physicians based on rotating schedules rather than patient or referring physician preferences, helping to minimize referral bias."
