In 2014, the Association of State and Territorial Health Officials (ASTHO) convened a multistate Immediate Postpartum Long-Acting Reversible Contraception (LARC) Learning Community to facilitate cross-state collaboration in implementation of policies. The Learning Community model was based on systems change, through multistate peer-to-peer learning and strategy-sharing activities. This study uses interview data from 13 participating state teams to identify state-implemented strategies within defined domains that support policy implementation.
