The aim of this report was to understand the sociodemographic and geographic distribution of substance use disorder (SUD) prevalence in Maine, through a claims-based analysis which assessed current statewide capacity to address SUD by examining current SUD treatment and recovery infrastructure, service utilization patterns, and geographic distribution of services and usage throughout the state to identify any gaps in treatment and recovery capacity.

The authors would like to note that this report was completed during the planning phase of the SUPPORT for ME project, which was funded by the Centers for Medicare & Medicaid Services (CMS) via the SUPPORT Act passed by Congress in 2018. This assessment utilized numerous data sources, one of which was Medicaid claims data from Maine’s Office of MaineCare Services. This was the first attempt to utilize claims data to estimate prevalence and capacity related to SUD in the State. In future work, the authors aim to have more engagement with clinical providers and data stakeholders which may lead to alterations or updates to the methodologies utilized to produce this report.
