RESTORE Study R61 Phase: Recovery and Engagement for Stimulant Users on Re-entry

DynamiCare is a mobile contingency management (CM) platform. Participants randomized to this intervention receive access to the DynamiCare app, an FDA-approved mobile application that delivers CM through features such as at-home saliva drug testing, appointment check-ins, and incentives for healthy behaviors. The app is designed to promote substance use reduction and engagement in care by providing financial rewards for meeting health-related goals. The intervention aims to improve initiation and retention in HIV prevention or treatment (PrEP or ART), reduce stimulant use, and enhance overall health outcomes among justice-involved individuals.

Participants work with a trained patient navigator (PN) who provides individualized support, assists with linkage to medical and social services, and helps address barriers to care. The PN meets with participants weekly during the first month and biweekly thereafter to conduct a comprehensive needs assessment and provide tailored support. This includes assistance with obtaining housing, identification, insurance, transportation, and linkage to health and social services such as HIV prevention or treatment (PrEP/ART), substance use disorder treatment, and other community-based care. The navigation protocol follows established procedures from prior studies (e.g., ACTION). All participants receive a smartphone to support communication and appointment coordination.
