Emergency physician gender is associated with early pregnancy loss management: a multisite retrospective cohort study.

BACKGROUND: Patients experiencing early pregnancy loss often first present to the emergency department (ED) where they can be managed non-operatively through expectant or medical management, or surgically by the obstetrical team. Studies have reported that physician gender can influence clinical decision making, but there is limited research on this phenomenon in the ED. The objective of this study was to determine whether emergency physician gender is associated with early pregnancy loss management. METHODS: Data were retrospectively collected from patients who presented to Calgary EDs with a non-viable pregnancy from 2014 to 2019. Pregnancies >12 weeks gestational age were excluded. The emergency physicians included saw at least 15 cases of pregnancy loss over the study period. The primary outcome was obstetrical consult rates by male versus female emergency physicians. Secondary outcomes included rates of initial surgical evacuation via dilation and curettage (D&C) procedures, ED returns, returns to care for D&Cs and total D&C rates. Data were analysed using χ2, Fisher's exact and Mann-Whitney U tests, as appropriate. Multivariable logistic regression models accounted for physician age, years of practice, training programme and type of pregnancy loss. RESULTS: 98 emergency physicians and 2630 patients from 4 ED sites were included. 76.5% of the physicians were male accounting for 80.4% of pregnancy loss patients. Patients seen by female physicians were more likely to receive an obstetrical consultation (adjusted OR (aOR) 1.50, 95% CI 1.22 to 1.83) and initial surgical management (aOR 1.35, 95% CI 1.08 to 1.69). ED return rates and total D&C rates were not associated with physician gender. CONCLUSION: Patients seen by female emergency physicians had higher rates of obstetrical consultation and initial operative management compared with those seen by male emergency physicians, but outcomes were similar. Additional research is required to determine why these gender differences exist and how these discrepancies may impact the care of early pregnancy loss patients.
