Collaborative Care Model for Patients With Opioid Use Disorder and Mental Illness

Opioid use disorders (OUDs) remain undertreated, particularly when co-occurring with mental illness. The collaborative care model (CoCM), an evidence-based approach for integrating behavioral health treatment in primary care, offers a potential solution, but the extent to which the CoCM can engage high-risk populations with fidelity in community settings is poorly understood. The present study used data from a CoCM trial for OUD co-occurring with mental illness to examine patient characteristics associated with CoCM engagement and fidelity.
