Abstract

Background: Alcohol use disorder (AUD) affects 1 in 10 Veterans and is associated with significant morbidity and mortality. However, few individuals receive evidenced-based psychosocial interventions or medications for AUD (MAUD). Common barriers to treatment include long wait times, stigma, and distance from treatment facilities. Despite clinical guidelines and evidence indicating superior outcomes, even fewer individuals receive MAUD and psychosocial interventions conjointly. The VA prioritizes expanding access to AUD interventions in primary care, but it is difficult to deliver psychosocial interventions in primary care, and care often includes MAUD only. Smartphone mobile applications (apps) that deliver psychosocial interventions concurrent with MAUD may address the gap between recommended and current practices for AUD and appeal to Veterans who prefer to receive their AUD care in primary care. Alcohol intervention apps have been associated with improved drinking-related and mental health outcomes. Self-monitoring of alcohol use, a common feature in apps, may also increase MAUD adherence. Step Away, an app for self-management of alcohol use problems, is designed to guide development and use of personalized strategies to moderate or abstain from drinking. In single-arm cohort studies, we assessed the acceptability and usability of Step Away and Stand Down (SD- App), the Veteran version of the app and focus of this proposal, among Veterans with alcohol use problems. The apps received favorable ratings regarding perceived effectiveness, efficiency, and overall satisfaction, and were associated with reductions in heavy drinking days and drinking-related consequences. Significance: This study has the potential to substantially improve Veterans’ receipt of guideline-concordant AUD care and support national VA initiatives to increase access to AUD care in general healthcare clinics. Innovation & Impact: To our knowledge, no prior study has evaluated the effectiveness of an alcohol-related intervention, delivered by smartphone, with MAUD in primary care. Smartphone apps can be scaled up at relatively low cost, potentially saving lives and improving the quality of care of tens of thousands of Veterans. Specific Aims: Our two aims are to: 1) determine whether MAUD plus SD-App offered to primary care patients diagnosed with AUD, compared to MAUD only, results in (a) greater reductions in heavy drinking days, from baseline to 6-months (primary), (b) greater improvements in alcohol consequences, alcohol use risk levels, and mental health outcomes, from baseline to 6-months (secondary), 2) conduct a process evaluation to identify factors that influence the adoption, implementation, and sustainability of SD-App in combination with MAUD in VA primary care from Veterans’, clinical pharmacist specialists’ and clinical leaders’ perspectives. We will also explore whether MAUD plus SD-App increases MAUD 6-month adherence relative to SD-App alone. Methodology: Guided by the Reach, Effectiveness, Adoption, Implementation, and Maintenance framework, this Hybrid 1 effectiveness-implementation trial will enroll 330 Veterans across 10 VA sites. Veterans between ages 18-80, meeting AUD criteria, and planning to initiate MAUD will be randomized to MAUD+SD-App or MAUD only. Participants randomized to MAUD+SD-App will receive access to SD-App. MAUD will be prescribed by primary care-based clinical pharmacists per standard clinical care. The primary and secondary outcomes will be assessed at baseline, 3-, 6- and 12-months using participant self-report and electronic medical record data. We will complete qualitative interviews to assess Veterans’, clinical pharmacists’, and clinical leaders’ perspectives on barriers and facilitators to adoption, implementation, and sustainability of SD- App in combination with MAUD in primary care. Next Steps/Implementation: If MAUD+SD-App improves drinking outcomes, we will work closely with our operations partners to review study findings and to develop a tailored implementation strategy to support widespread implementation across VA primary care.
