Expansion and evaluation of level II and III recovery residences for people taking medications for an opioid use disorder: project HOMES (Housing for MAR Expanded Services) study protocol.

Introduction: As the US continues to battle the opioid epidemic, recovery residences remain valuable services for people in recovery. While there is a growing body of literature describing positive outcomes experienced by people who live in recovery residences, little is known about the experience of people who live in these residences while taking medications for an opioid use disorder (MOUD) as part of their recovery. Thus, this study has three aims: (1) expand the availability of recovery residences that meet the National Alliance for Recovery Residences standards in Texas and serve individuals taking medications for an opioid use disorder as part of their recovery; (2) evaluate recovery residences for people taking MOUD as part of their recovery; and (3) compare the cost-effectiveness of recovery residences to treatment-as-usual.
