Objective: To evaluate whether the use of long-acting, reversible contraception (LARC) is equitably accessible to Medicaid recipients in rural and urban areas. We also determined whether women's health specialists' availability was associated with the type of LARC used. Study design: We used claims data for 242,057 adult women who were continuously enrolled in Oregon Medicaid for at least one year and at risk of pregnancy from January 1, 2015, through December 31, 2017 to assess the association between LARC utilization and (1) rurality and (2) provider supply. Our primary analysis included 430,918 person-years. Regression models adjusted for patient age, whether the patient was newly eligible for Medicaid due to Medicaid expansion, and health status. We also examined differences in the caseload of implants and IUD by provider type (women's health specialist vs other). Results: Among all women, 11.6% had at least one claim indicating LARC use. There was no significant difference in overall LARC use by location (urban residence +0.66%, 95% CI [-0.12%, 1.43%]), although urban residents were slightly more likely to have an IUD (+0.72%, 95% CI [0.11%, 1.33%]). An increase of one women's health specialty provider per 10,000 women was associated with a 0.14 percentage point increase in the rate of IUD utilization (95% CI: 0.02, 0.26). Compared to other providers, women's health specialty providers supplied 62% of all IUDs and 43% of all implants. Conclusion: Among Oregon's Medicaid enrollees, LARC is equitably used in rural areas; however, IUD use is slightly more frequent in urban areas.
