Mifepristone for miscarriage treatment in Utah: A survey of clinician knowledge and assessment of an educational video on future use.

Objectives: We aimed to: (a) describe current use of mifepristone for early pregnancy loss (EPL) management in Utah, (b) identify predictors of knowledge pre- and posteducational video, and (c) explore postvideo impacts on the likelihood to use mifepristone. Mifepristone is subject to the Food and Drug Administration's (FDA) Risk Evaluation and Mitigation Strategy (REMS) requirements.

Methods: Between September 2020 and March 2021 we surveyed Utah clinicians from six specialties caring for people experiencing EPL, recruited through professional organizations and hospital listservs. Participants viewed a 3.5-minute educational video on mifepristone for EPL and completed pre- and postvideo questionnaires. We evaluated predictors of high prevideo and improved postvideo knowledge using random forest regression conditional importance measures and partial dependency plots. We described current mifepristone use and video effects on likelihood to use mifepristone.

Results: Of 506 participants, most specialize in emergency medicine (172, 34%) and practice in private settings (253, 51%). Two-thirds had heard of mifepristone (328/471, 70%). Of 176/471 (37%) attempting provision of mifepristone, actual provision occurred for 59% (104/176). Baseline knowledge scores were low (mean 4.81/13 [37%] correct). Predictors of high prevideo knowledge include provision or attempted provision of mifepristone, having heard of mifepristone, providing EPL management expectantly or via medication, and specialty type. Mean postvideo knowledge scores improved by 3.27 points (68% improvement, paired t-test; 95% confidence interval 2.82-3.72, p < 0.0001). Postvideo, 66% (242/364) stated they are much more or somewhat more likely to use mifepristone, with compliance with FDA requirements cited as a barrier to utilization.

Conclusions: Among Utah providers, baseline mifepristone knowledge and use for EPL management are low. An educational video improved knowledge and likelihood of use, but FDA REMS requirements continue to be a barrier to including mifepristone in medication management of EPL.
