This study aims to improve access to treatment for substance use disorders (SUD) in southern jails, focusing on groups that are overrepresented in jails and lack access to important medications for opioid addiction, like methadone and buprenorphine. The study addresses individual needs and types of substance use by implementing and evaluating a Peer Recovery Coaches (PRC) program, which includes motivational interviewing and connecting people to medical, behavioral, and community services in three busy jails in Atlanta, Georgia. It uses “LINCS UP,” a telehealth model adapted to the jail environment that entails collaborating with a board of people with a history of SUD and justice involvement. The effectiveness of PRCs is measured by tracking how well they help individuals engage in addiction treatment while in jail and connect to community care after release. Other outcomes assessed include substance use patterns, recovery progress, overdose rates, mortality, and whether individuals return to jail. The study also analyzes the costs of the PRC program, considering both healthcare and societal impacts.
