The Whole Health Study: Collaborative Care for OUD and Mental Health Conditions

CC is delivered using the investigators' Foundations for Integrated Care model. The first line pharmacotherapy is buprenorphine-naloxone. The second line pharmacotherapy included is extended-release injectable naltrexone. Pharmacotherapy is accompanied by brief problem-solving therapy, cognitive-behavioral therapy, and/or motivational interviewing. The primary care physician, in consultation with the addictions psychiatrist and care manager, also will provide psychotropic medications for psychiatric disorders. In-person and telephone visits consist of the care manager carrying out intervention activities over 6 months. Visits are at baseline (90-minute intake appointment), home or office induction when in moderate opiate withdrawal if buprenorphine is prescribed, twice a week for two weeks with telephone calls in between visits, then weekly, and when stable once a month. There will be a final visit at 6 months. The intervention includes routine collection of urine drug screens.

If not already waivered, PCPs will be trained and waivered to treat OUD with medications. All practices will have mental health clinicians to treat mild psychiatric disorders. Other than that, the research team will provide no support to the PCP or practice staff. However, an addiction psychiatrist is available for consultation for OUD.

This intervention includes the Collaborative Care Intervention plus Certified Recovery Specialist to assist with treatment engagement and retention.
