Our New Hampshire baseline needs assessment, conducted in collaboration with the New Hampshire Citizens Health Initiative at the University of New Hampshire Institute for Health Policy and Practice, aimed to identify current and future substance use disorder (SUD) treatment needs and barriers in rural counties with input from practitioners and community stakeholders. This data brief focuses on practitioners’ and community stakeholders’ reported barriers and challenges to treating patients with opioid use disorder (OUD) and beliefs about treating patients using medications for OUD (MOUD).
