Abstract

Background: Many states are implementing comprehensive programs aimed at reducing persistent barriers to contraceptive care. Evidence on the effectiveness of these programs is essential for practice improvement and policy development. Objective: To evaluate changes in the probability of initiating a contraceptive method by women with employer sponsored insurance after implementation of Delaware Contraceptive Access Now (DelCAN), a statewide initiative that aimed to increase access to long-acting reversible contraceptives (LARCs). Design, setting, and participants: We used a difference-in-differences design to examine contraceptive initiation rates. Data came from IBM Marketscan and covered women age 15–44 enrolled in employer sponsored insurance. The primary outcome was insertion of a LARC, both in the overall study population and in the immediate postpartum (IPP) setting. Secondary analysis examined changes to other contraceptive method types. Results: The cohort of 4,550,459 enrollees generated a sample of 11,888,837 person-years and 615,670 childbirth hospitalizations. Difference-in-differences estimates suggested that DelCAN was associated with a 0.3 percentage point (95% CI [0.2, 0.5], p
