Addressing Barriers to Care for Substance Use Disorder Pilot Study

The Addressing Barriers to Care for Substance Use Disorder Pilot (ABC-SUD Pilot) was a randomized pilot study that preceded a larger trial. The ABC-SUD Pilot was a parallel group, cluster-randomized pilot feasibility trial, with clinicians (care coordinators) as the unit of randomization. This study was conducted in a mental health treatment access center within the Washington region of Kaiser Permanente. As part of usual care, patients contacted the mental health access center to speak to a "care coordinator" to obtain contact information for potential venues to obtain treatment for substance use disorder. The experimental intervention, Care Navigation, was evaluated for its potential to increase the utilization of substance use disorder treatment among patients who contacted the mental health treatment access center. The investigators note that Care Navigation was delivered by study "care navigators", who were distinct from the health system's care coordinators.
