Improving retention across the OUD service cascade upon reentry from jail using Recovery Management Checkups-Adaptive (RMC-A) experiment.

Incarcerated individuals with opioid use disorders (OUD) should be linked to community-based treatment with medications for opioid use disorder (MOUD) upon their release, as well as to services that provide support for their ongoing recovery. The RMC-A experiment will test an adapted version of the evidence-based Recovery Management Checkups (RMC), which provides treatment linkage, support for retention, and re-linkage as indicated at quarterly checkups. A total of 750 male and female individuals will be recruited from 5 county jails in Illinois and randomly assigned to 1 of 3 groups at release from jail: a) Monitoring and Treatment Referral (MTR); b) quarterly RMC (RMC-Q); or c) RMC-A, which adjusts the frequency and intensity of checkups based on the individual's assessed need for treatment at each checkup. Measurement includes quarterly research follow-up assessments for 2 years, urine tests, and records checks (treatment, mortality, recidivism). The study aims to evaluate: (1) the direct effects of RMC-Q/RMC-A on MOUD treatment initiation, engagement, retention, and re-linkage; (2) the indirect effects of RMC-Q/RMC-A (via months of MOUD) on public health outcomes (days of opioid use, OUD symptoms, quality of life, cost of health care utilization); (3) the indirect effects of RMC-Q/RMC-A (via months of MOUD and public health outcomes) on public safety outcomes (illegal activity, re-arrest, re-incarceration, cost of crime); and (4) the incremental costs and cost-effectiveness of MTR vs. RMC-Q vs. RMC-A on public health and public safety outcomes. This experiment will determine whether the adapted RMC model improves the overall effectiveness and cost-effectiveness of the fixed quarterly RMC.
