Impact of opioid maintenance therapy in the community on re-incarceration in individuals with opioid use disorder-A linked cohort study.

Introduction: Studies have found associations between Opioid Agonist Maintenance Treatment during incarceration and reduced recidivism among recently released formerly incarcerated persons. However, the role of community-based Opioid Agonist Maintenance Treatment in reducing recidivism post-release remains less explored. This study examines whether pre-release arranged, prison-to-rehabilitation Opioid Agonist Maintenance Treatment in the community following release is associated with reduced rates and lengths of re-incarceration among justice-involved individuals with Opioid Use Disorder.

Methods: A retrospective matched cohort study was conducted using linked records of 208 individuals with a history of Opioid Use Disorder and treatment during their incarceration. The primary predictor variable was the duration of Opioid Agonist Maintenance Treatment, with re-incarceration rates and lengths of stay after re-incarceration being the primary outcomes examined.

Results: Analysis showed a significant decrease in re-incarcerations and or lengths of stay in prison among those who have been re-incarcerated and have undergone Opioid Agonist Maintenance Treatment in the community for >24 months.

Conclusions: Maintaining Opioid Agonist Maintenance Treatment over 24 months may reduce re-incarcerations, and may be significantly associated with a reduction in the length of prison stay for re-incarcerated individuals. The effects were consistent across the overall population and the individuals receiving the treatment. Various other unmeasured factors, including judicial discretion, individual motivation, type of offense, and employment status, could influence this association.
