Elderly patients who are cared for by a female physician
when hospitalized are less likely to die or to be readmitted than similar
patients whose physicians are men, Harvard researchers have found.
"These findings suggest that the differences in
practice patterns between male and females physicians, as suggested in previous
studies, may have important clinical implications for patient outcomes," Yusuke
Tsugawa, MD, MPH, PhD and colleagues wrote in JAMA Internal Medicine.
The researchers analyzed a 20% random sample of Medicare
fee-for-services patients who were hospitalized with a medical condition and
treated by general internists. The study period was Jan. 1, 2011 to Dec. 31,
2014.
They looked at 30-day mortality, readmission rates, then
they adjusted to effectively compare female and male physicians with the same
hospital.
The data showed that the adjusted mortality rate for
patients treated by female internists was 11.07% vs. 11.49% for those treated
by their male counterparts.
There was a similar disparity in readmission rates, or
15.02% for patients with female doctors and 15.57% for those with male doctors.
A possible explanation could be that the women doctors were
more likely to adhere to clinical guidelines, "provide preventive care
more often, use more patient-centered communication, and provide more
psychological counseling," the authors said.
Their study was also designed to build a case for better pay
for women.
In an accompanying editorial, Anna Parks, MD and Rita
Redberg, MD, MSc, noted that salaries for female academic physicians are about
$19,879 lower, or 8.0% less than those of male colleagues.
They also cited studies that showed that women doctors
"are more encouraging and reassuring, and have longer visits than male
physicians," and that ironically the very behaviors that lead to these
better patient outcomes are discouraged by pay-for-performance initiatives that
stress increasing the volume of patient encounters in a given day.
The editorial writers said the study findings should be used
to "promote equity in start-up packages, career advancement, and
remuneration for all physicians."

Key Points
Question Do patient
outcomes differ between those treated by male and female physicians?
Findings In this
cross-sectional study, we examined nationally representative data of
hospitalized Medicare beneficiaries and found that patients treated by female
physicians had significantly lower mortality rates (adjusted mortality rate,
11.07% vs 11.49%) and readmission rates (adjusted readmission rate, 15.02% vs
15.57%) compared with those cared for by male physicians within the same
hospital.
Meaning Differences
in practice patterns between male and female physicians, as suggested in
previous studies, may have important clinical implications for patient
outcomes.
Abstract
Importance Studies
have found differences in practice patterns between male and female physicians,
with female physicians more likely to adhere to clinical guidelines and
evidence-based practice. However, whether patient outcomes differ between male
and female physicians is largely unknown.
Objective To
determine whether mortality and readmission rates differ between patients
treated by male or female physicians.
Design, Setting, and Participants We analyzed a 20% random sample of Medicare
fee-for-service beneficiaries 65 years or older hospitalized with a medical
condition and treated by general internists from January 1, 2011, to December
31, 2014. We examined the association between physician sex and 30-day mortality
and readmission rates, adjusted for patient and physician characteristics and
hospital fixed effects (effectively comparing female and male physicians within
the same hospital). As a sensitivity analysis, we examined only physicians
focusing on hospital care (hospitalists), among whom patients are plausibly
quasi-randomized to physicians based on the physician’s specific work
schedules. We also investigated whether differences in patient outcomes varied
by specific condition or by underlying severity of illness.
Main Outcomes and Measures
Patients’ 30-day mortality and readmission rates.
Results A total of
1 583 028 hospitalizations were used for analyses of 30-day mortality (mean
[SD] patient age, 80.2 [8.5] years; 621 412 men and 961 616 women) and
1 540 797 were used for analyses of readmission (mean [SD] patient age, 80.1
[8.5] years; 602 115 men and 938 682 women). Patients treated by female
physicians had lower 30-day mortality (adjusted mortality, 11.07% vs 11.49%;
adjusted risk difference, –0.43%; 95% CI, –0.57% to –0.28%; P < .001; number
needed to treat to prevent 1 death, 233) and lower 30-day readmissions
(adjusted readmissions, 15.02% vs 15.57%; adjusted risk difference, –0.55%; 95%
CI, –0.71% to –0.39%; P < .001; number needed to treat to prevent 1
readmission, 182) than patients cared for by male physicians, after accounting
for potential confounders. Our findings were unaffected when restricting
analyses to patients treated by hospitalists. Differences persisted across 8
common medical conditions and across patients’ severity of illness.
Conclusions and Relevance
Elderly hospitalized patients treated by female internists have lower
mortality and readmissions compared with those cared for by male internists.
These findings suggest that the differences in practice patterns between male
and female physicians, as suggested in previous studies, may have important
clinical implications for patient outcomes.
