Cost-effectiveness of Mifepristone Pretreatment for the Medical Management of Nonviable Early Pregnancy: Secondary Analysis of a Randomized Clinical Trial.

ABSTRACT: Importance:Early pregnancy loss (EPL) is the most common complication of pregnancy. A multicenter randomized clinical trial compared 2 strategies for medical management and found that mifepristone pretreatment is 25% more effective than the standard of care, misoprostol alone. The cost of mifepristone may be a barrier to implementation of the regimen. Objective:To assess the cost-effectiveness of medical management of EPL with mifepristone pretreatment plus misoprostol vs misoprostol alone in the United States. Design, Setting, and Participants:This preplanned. prospective economic evaluation was performed concurrently with a randomized clinical trial in 3 US sites from May 1, 2014, through April 30, 2017. Participants included 300 women with anembryonic gestation or embryonic or fetal demise. Cost-effectiveness was computed from the health care sector and societal perspectives, with a 30-day time horizon. Data were analyzed from July 1, 2018, to July 3, 2019. Interventions:Mifepristone pretreatment plus misoprostol administration vs misoprostol alone. Main Outcomes and Measures:Costs in 2018 US dollars, effectiveness in quality-adjusted life-years (QALYs), and treatment efficacy. Incremental cost-effectiveness ratios (ICERs) of mifepristone and misoprostol vs misoprostol alone were calculated, and cost-effectiveness acceptability curves were generated. Results:Among the 300 women included in the randomized clinical trial (mean [SD] age, 30.4 [6.2] years), mean costs were similar for groups receiving mifepristone pretreatment and misoprostol alone from the health care sector perspective ($696.75 [95% CI, $591.88-$801.62] vs $690.88 [95% CI, $562.38-$819.38]; P?=?.94) and the societal perspective ($3846.30 [95% CI, $2783.01-$4909.58] vs $4845.62 [95% CI, $3186.84-$6504.41]; P?=?.32). The mifepristone pretreatment group had higher QALYs (0.0820 [95% CI, 0.0815-0.0825] vs 0.0806 [95% CI, 0.0800-0.0812]; P?=?.001) and a higher completion rate after first treatment (83.8% vs 67.1%; P?
