The experiment will be conducted in collaboration with 6 jails representing discrete geographic counties in Illinois and the opioid treatment providers (OTP) that serve them. It will compare a re-entry as usual control group with two experimental groups in terms of their impact on the OUD service cascade, as well as public health and public safety outcomes. Study recruitment sites are six jails that provide treatment with medication for opioid use disorder (MOUD) to inmates with OUD prior to their release. At the time of their release to the community, 750 men and women will be randomly assigned to 1 of 3 groups: a) a re-entry as usual control, b) RMC with monthly checkups for 3 months post-release followed by quarterly checkups up to 2 years, or c) an adaptive version of RMC (RMC-A) that includes a modified checkup schedule based on each individual's pattern of treatment need. All participants will complete research interviews at release and quarterly thereafter up to 2 years post-enrollment.
