Moniz MH, Peahl AF, Fendrick AM, et al. - Researchers examined if and how cost sharing for long-acting reversible contraception affects postpartum contraception use patterns and pregnancies in the 12 months after delivery. From Optum’s (Eden Prairie, MN) de-identified Clinformatics Data Mart database, they included commercially insured women undergoing childbirth from 2014 to 2018 for performing this retrospective cohort analysis. In this large national database, nonretired employees and their dependents who are enrolled in health insurance plans sponsored by large- or medium-sized US-based employers, are included. They identified 25,298 plans with cost sharing data. A total of 172,941 women with continuous enrollment for 12 months postpartum were identified comprising 82,500 (47.7%) in no cost sharing, 22,595 (13.1%) in low cost sharing, and 67,846 (39.2%) in high cost sharing plans. At all time points, there was a higher likelihood of using long-acting reversible contraceptive and a lower likelihood of using no prescription method among postpartum women in no cost sharing plans vs in low or high cost sharing plans. Findings overall suggest the influence of out-of-pocket costs for long-acting reversible contraception on the method of contraception used by postpartum women with employer-based insurance. They indicate the possibility that elimination of financial barriers to long-acting reversible contraception access after childbirth may aid women to initiate their preferred method and improve the use of long-acting reversible contraceptives among interested women who otherwise might utilize less effective methods.
