About
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.
Full description
The ABC-SUD Trial is a cluster-randomized crossover trial evaluating the effectiveness of care navigation in increasing engagement in substance use disorder treatment. Each care coordinator is randomly assigned to a study arm (services as usual or care navigation) at the beginning of the trial (period 1), and halfway through the trial, switches to the other study arm (period 2). The patient population includes individuals who are seeking substance use treatment and are evaluated by enrolled care coordinators.
During periods in which care coordinators are assigned to the intervention arm, care coordinators offer care navigation to patients and utilize an electronic health record referral tool to refer patients to care navigators. This tool is disabled for care coordinators during the period in which they are assigned to the control arm.
This study will employ an encouragement design, where patients who speak with intervention care coordinators are offered care navigation, but patients choose whether to participate in care navigation. Primary analyses will follow an intent-to-treat principle whereby care coordinators and patients will be analyzed according to the intervention arm to which they are assigned regardless of the subsequent sequence of events.
