A new study looked at peer health navigation experiences before and after prison release amount people with opioid use disorder. “Our study looked at the experiences of participants in a specific peer navigation program that paired people with opioid use disorder exiting incarceration with peer navigators and other supports,” study author Michael Enich told us. “We were hoping to capture, in their own words, program participants’ feelings working with peers who have also experienced incarceration and/or substance use or mental health challenges. We also wanted to see what aspects of the program these participants found to be most helpful—or aspects of the program they would change if they could.” [More]
