Introduction Medication assisted treatment (MAT) is a proven recovery solution for people experiencing opioid use disorder (Maglione et al, 2018). Integration, expansion, and accessibility of recovery and harm reduction services is lacking due to minimal funding and provider capacity for addiction treatment (Rural Project Summary, 2021). Transportation can also be a significant barrier for marginalized, disabled, and individuals in rural settings in obtaining comprehensive opioid treatment (Greenfield et al., 1996). The project has three goals: to increase access to MAT and substance use disorder counseling, to increase patient retention, and to connect individuals to ongoing recovery resources by partnering with mission-aligned organizations. This paper details research findings surrounding estimated costs of the implementation and operationalization of a mobile opioid treatment program (OTP), identifying opportunities for collaboration with other harm-reduction focused organizations in the Portland metro and Oregon north coastal areas, and providing the framework for mobile OTP implementation.
