Collaboration Leading to Addiction Treatment and Recovery from Other Stresses (CLARO) is a five-year project that tests whether delivering care using a collaborative model helps patients with both opioid use disorders and mental health disorders.

Official Title

Improving Access and Treatment for Co-occurring Opioid Use Disorders and Mental Illness


Untreated mental illness and substance use disorders are prevalent and can have devastating consequences for the individual, their families and the community. Co-occurring opioid use disorders (OUD) with either depressive disorders and/or post-traumatic stress disorder (PTSD) are of particular concern, because depression and PTSD are prevalent in people with OUD, co-occurring mental illness is linked to an increased risk for opioid misuse and overdose, and because of the high prevalence of the chronic use of prescription opioids in individuals with mental illness, a risk factor for heroin use and the development of an OUD. Primary care is an important and underutilized setting in which to provide treatment for all three disorders, because OUD, depression and PTSD are frequently co-morbid with medical conditions. However, despite the effectiveness of treatments for all three disorders, many individuals never receive treatment; and, when treatment is provided, quality is low. With the rising number of opioid-related fatalities, this is a critical treatment and quality gap in a vulnerable and stigmatized population. Collaborative care (CC) has never been tested with co-occurring disorders (COD), despite research by our team suggesting it may be effective. CC consists of a team of providers that includes a care coordinator, a primary care provider (PCP) and a behavioral health consultant (BHC), who provide evidence- and measurement-based care to a panel of patients using a clinical registry. In our CC model for COD (CC-COD), the CC team also includes a behavioral health psychotherapist (BHP); the evidence-based treatments supported include medications for OUD (MOUD), pharmacotherapy for depression and PTSD, motivational interviewing (MI), problem solving therapy (PST) and Written Exposure Therapy (WET).

The current study consists of a multi-site, randomized pragmatic trial in rural and urban primary care clinics located in Health Professional Shortage Areas (HPSA) of New Mexico and California to adapt, harmonize and then test whether CC-COD improves access, quality and outcomes for primary care patients with co-morbid OUD and depression and/or PTSD. The study will randomize 900 patients with co-occurring OUD and depression disorder and/or PTSD to receive either CC-COD or enhanced usual care (EUC).
