Postpartum long-acting reversible contraceptive adoption after a statewide initiative

To examine the effects of a comprehensive, multiyear (2015-2020) statewide contraceptive access intervention in Delaware on the contraceptive initiation of postpartum Medicaid patients. The program aimed to increase access to all contraceptives, including long-acting reversible contraceptives (LARC). The program included interventions specifically targeting postpartum patients (Medicaid payment reform and hospital-based immediate postpartum (IPP) LARC training) and interventions in outpatient settings (provider training and operational supports).

We used Medicaid claims data between 2012 and 2019, from Delaware and Maryland (a comparison state), to identify births and postpartum contraceptive methods up to 60 days postpartum among patients aged 15-44 years who were covered in a full-benefit eligibility category.

Using difference-in-differences, we assessed changes in LARC, tubal ligation, and short-acting methods (oral contraceptive, injectable, patch/ring). LARC rates were assessed at 60 days after delivery and on an immediate postpartum basis. Other methods were only assessed at 60 days. Analyses were conducted separately for an early-adopting high-capacity hospital (that delivers approximately half of all Medicaid financed births) and for all other later-adopting hospitals in the state.

Data were extracted from administrative claims.

The program increased postpartum LARC insertions by 60 days after delivery by 11.7 percentage points (95% CI: 10.7, 12.8) in the early-adopting hospital and 6.9 percentage points (95% CI: 4.8, 5.9) in later-adopting hospitals. Increases in IPP versus outpatient LARC drove the change, but we did not find evidence that IPP crowded-out outpatient LARC services. We observed decreases in short-acting methods, suggesting substitution between methods, but the share of patients with any method increased at the early-adopting hospital (5.2 percentage points; 95% CI: 3.5, 6.9) and was not statistically significantly different at the later-adopting hospitals.

Direct reimbursement for IPP LARC, in combination with provider training, had a meaningful impact on the share of Medicaid-enrolled postpartum women with LARC claims.
