Medical management of early pregnancy loss with mifepristone and misoprostol in emergency departments compared to a Complex Family Planning office: Implementation of a COVID-19 institutional policy change.

OBJECTIVES

To evaluate the implementation of mifepristone and misoprostol for medical management of early pregnancy loss (EPL) in emergency departments (EDs) by comparing efficacy, complication, and follow-up rates for patients treated in EDs to the Complex Family Planning (CFP) outpatient office.

STUDY

DESIGN

In COVID-19's first wave, we expanded medical management of EPL to our EDs. This retrospective study evaluated 72 patients receiving mifepristone and misoprostol for EPL from April 1, 2020 to March 31, 2021, comparing treatment success, safety outcomes, and follow-up rates by location.

RESULTS

Thirty-three (46%) patients received care in the ED and 39 (54%) at CFP. Treatment success was lower in EDs (23, 70%) compared to CFP (34, 87%), but after adjusting for insurance status and pregnancy type (miscarriage, uncertain viability, unknown location), this was not significant: adjusted odds ratio 0.48 (95% CI 0.13-1.81). More ED patients underwent emergent interventions (3 vs 0) including two emergent uterine aspirations, one uterine artery embolization, and two blood transfusions. Two cases were attributed to misdiagnosis (cesarean scar and cervical ectopic pregnancies interpreted as incomplete miscarriages) and one to guideline nonadherence. No complications occurred in the CFP group. Follow-up rates were over 80% in both groups. More ED patients engaged in telehealth follow-up (67% vs 18%, p ≤ 0.0001).

CONCLUSIONS

In this small sample, we observed a trend toward less successful treatment in the ED compared to the CFP office. Both correctly making uncommon diagnoses and adhering to new guidelines presented implementation challenges.

IMPLICATIONS: Implementing mifepristone and misoprostol for EPL in our EDs achieved lower rates of pregnancy resolution compared to outpatient management. Complex uncommon diagnoses and implementing new care pathways in EDs may have contributed to complications and highlighted opportunities for improvement. Additional studies are needed to further quantify safety outcomes for EPL management in EDs.
