Delaware Contraceptive Access Now was a statewide contraceptive access program implemented in Delaware between 2015 and 2020. We evaluated the association of the program with contraceptive initiation in Delaware's Medicaid program using a difference-in-differences design that compared changes in Delaware to changes in Maryland. Results suggest that program implementation was associated with increased initiation of long-acting reversible methods, particularly among adolescent patients aged 15 to 18 years. We found less-consistent evidence for changes to any contraceptive method. (Am J Public Health. 2022;112(S5):S537-S540. https://doi.org/10.2105/AJPH.2022.306938).
