Management of early pregnancy loss among obstetrician-gynecologists in Massachusetts and barriers to mifepristone use

Abstract

Objectives: To measure the prevalence of early pregnancy loss management types among obstetrician-gynecologists in Massachusetts, and delineate barriers, facilitators, demographic and practice-related factors associated with mifepristone use for early pregnancy loss.

Study design: We surveyed a census of obstetrician-gynecologists in Massachusetts. Descriptive statistics measured the prevalence of offering expectant, misoprostol-alone, mifepristone and misoprostol, dilation and curettage in the office and operating room, and multivariate logistic regression analysis evaluated barriers and facilitators to mifepristone use. Data were weighted to account for nonresponders.

Results: 198 obstetrician-gynecologists responded to the survey (response rate=29%). Participants most commonly offered expectant management (98%), dilation and curettage in the operating room (94%), and misoprostol-only medication management (80%). Fewer offered mifepristone-misoprostol (51%) or dilation and curettage in an office setting (45%). Those in private practice or other practice types had lower odds of offering mifepristone-misoprostol than those in academic practice (private practice: aOR 0.34, 95% confidence interval [CI] [0.19, 0.61]). Female physicians had higher odds of offering mifepristone-misoprostol (aOR 1.97, 95% CI [1.11, 3.49]). Obstetrician-gynecologists who included medication abortion in their practice had much higher odds of using mifepristone for early pregnancy loss (aOR 25.06, 95% CI [14.52, 43.24]). The Food and Drug Administration Risk and Evaluation Management Strategies Program was a primary barrier among those not using mifepristone (54%).

Conclusions: Many obstetrician-gynecologists do not offer mifepristone-based regimens for early pregnancy loss, which are more efficacious than misoprostol-only regimens. The Food and Drug Administration Risk Evaluation and Mitigation Strategies Program is a major barrier to mifepristone use.

Implications: Half of obstetrician-gynecologists in Massachusetts do not use mifepristone for early pregnancy loss management. Major barriers include lack of experience with mifepristone and the Food and Drug Administration Risk Evaluation and Mitigation Strategies Program regulations. Removing medically unnecessary regulations and increasing education on mifepristone via access to abortion care experts may increase uptake of this practice.
