Recovery management checkup (RMC) uses a structured, motivational-interviewing- based protocol delivered by linkage managers through regular check-ups. Chestnut Health Systems is conducting a hybrid type 2 effectiveness-implementation trial guided by the exploration, preparation, implementation, and sustainability (EPIS) framework which: 1) integrates RMC into community-based programs in four discrete areas in Chicago with the highest risk of substance-related fatality and arrest, and 2) tests the equivalence of client and implementation outcomes for RMC delivered by staff in community programs versus Chestnut research staff.
