We are interested in comparing 3 care conditions to determine which condition is best to help people with opioid use disorder (OUD) and mental illness reduce their drug use and improve their psychiatric symptoms. The model we are testing is called collaborative care. This model uses a team-based approach in which a primary care physician (PCP) and a care manager coordinate care. Care managers are hired in primary care practices to work as part of the health care team. As part of this study, care managers will keep their role and continue to provide care monitoring of patients with mental health conditions in the primary care practice. As part of this study, care managers in the experimental conditions will also receive training in treating patients with OUD. You will be offered medication for opioid use disorders (MOUD) such as buprenorphine. Buprenorphine, in combination with counseling, provides a whole-patient approach to the treatment of OUD. When taken as prescribed, buprenorphine is safe and effective. Buprenorphine lowers your risk for misuse and reduces withdrawal symptoms and cravings. It also helps reduce the chances of overdose.

You may be eligible for this study if you meet the following criteria:

• Conditions: Mental Health,OUD,Opoid use disorder
• Age: Between 18 Years - 99 Years
• Gender: All
