Addressing Barriers to Care for Substance Use Disorder Trial

The Addressing Barriers to Care for Substance Use Disorder Trial (ABC-SUD) is a cluster-randomized crossover trial, with clinicians (care coordinators) as the unit of randomization. This study will be conducted in a mental health access center within the Washington region of Kaiser Permanente. As part of usual care, patients contact the mental health access center and speak to a care coordinator to obtain an appointment with or contact information for potential venues to obtain treatment for substance use disorder. The experimental intervention, Care Navigation, will be evaluated for its potential to increase engagement in substance use disorder treatment among patients who contact the mental health access center. Care Navigation will be delivered by study care navigators, who are distinct from the health system\'s care coordinators.
