This Project Grant award from the National Institute on Drug Abuse (NIDA), under the Drug Use and Addiction Research Programs (CFDA 93.279), provides $945,397 to the Magee-Womens Research Institute and Foundation to adapt and evaluate a Collaborative Care Model (CCM) for providing comprehensive care to pregnant, postpartum, and parenting persons with opioid use disorder in low-resource and rural obstetric settings. The two-phase project aims to: 1) adapt the CCM approach for community-based, low-resource obstetric care settings, and 2) assess the impact of the adapted CCM on outcomes such as medication for opioid use disorder (MOUD) initiation and continuation, overdose prevention, and child removal rates. The research findings are expected to inform stakeholders on implementing CCMs in underserved areas and guide policymakers on adapting these models for wider replication.
