BackgroundUlipristal acetate (UPA) is a novel form of emergency contraception (EC) that appears to be more effective than the prevailing method, single-dose levonorgestrel (LNG). This study examines the cost-efficacy of UPA compared with LNG.Study DesignA decision-analytic model was developed to compare the cost-effectiveness of UPA versus LNG in preventing unintended pregnancy when taken within 120 h of unprotected intercourse. Univariate and bivariate sensitivity analyses, as well as Monte Carlo simulation and threshold analyses, were performed.ResultsUtilizing UPA instead of LNG would result in 37,589 fewer unintended pregnancies per 4,176,572 estimated US annual EC uses (UPA 54,295 pregnancies; LNG 91,884 pregnancies) and a societal savings of $116.3 million annually. Cost-effectiveness acceptability curve analyses suggest a 96% probability that UPA is more cost-effective at a willingness to pay $100,000 per quality-adjusted life year.ConclusionsUPA is cost-effective in preventing unintended pregnancy after unprotected intercourse. Efforts should be promoted to increase access to UPA.
