First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a program called the Transitions Clinic Network (TCN) for people leaving jail with opioid addiction. The program combines primary care, medication options, and a community health worker to address social needs. Researchers compared this to standard care and followed participants for a year to see if they stayed in treatment and avoided relapse.
