简要总结
Hazardous drinking is common among Veteran primary care patients and increases risk for more costly and complex medical problems over the long-term. Yet, the vast majority of these Veterans go untreated. By providing an option for care that is easily accessible, private, and self-directed, mobile applications (apps) circumvent many barriers to alcohol use treatment. However, poor patient engagement remains the Achilles' heel of these apps. Through supportive accountability, Peer Specialists can maximize the reach and engagement of these apps with patients and improve drinking outcomes. The goal of this project is to evaluate whether an app for alcohol use self-management ("Stand Down") reduces drinking among Veteran primary care patients who engage in hazardous drinking, and for whom Peer-Supported-Stand Down is more effective than the app alone. If successful, the proposed research has the potential to transform care and increase access to alcohol-related services for Veterans who engage in hazardous drinking but rarely seek treatment, and, in turn, mitigate the adverse health outcomes that stem from untreated hazardous drinking.
详细描述
One in four Veterans presenting to VA primary care screen positive for hazardous drinking. However, due to barriers such as Veterans' stigma about seeking alcohol use treatment and challenges with traveling to VA, most of these Veterans do not receive any alcohol-related care. Mobile applications (apps) are an innovative means of expanding access to alcohol use treatment. The evidence for mobile apps, such as "Step Away", to improve drinking outcomes is emerging. Nevertheless, poor patient engagement remains the Achilles' heel of these apps. Peer Specialists ("Peers") can facilitate Veterans' engagement with mobile apps intended for self-management of hazardous drinking by helping to orient patients to these apps and by providing technical support and accountability. In a VA HSR&D pilot study, the investigators created a Veteran version of the Step Away app ("Stand Down: Think Before You Drink") and conducted an open trial in which Veterans with hazardous drinking used the app while receiving Peer phone support. The intervention ("Peer-Supported [PS]-Stand Down") was highly acceptable to patients, and patients reported significant improvements in drinking outcomes. These data provide a strong foundation for a larger pragmatic trial to test the effectiveness of the Stand Down app and PS-Stand Down to reduce hazardous drinking among Veterans seen in primary care, relative to the current standard of care that these patients receive.
In the current study, the investigators will evaluate whether the Stand Down app reduces drinking among Veteran primary care patients who engage in hazardous drinking, and for whom PS-Stand Down is more effective than the app alone. Aim 1: Test whether Stand Down (vs. Usual Care; UC) and PS-Stand Down (vs. UC and vs. app only) predicts better drinking outcomes, and test mediators of these effects. Aim 2: Test for differences in satisfaction with care across conditions, and conduct qualitative interviews with patients and PACT staff to understand potential barriers/facilitators to implementing PS-Stand Down in primary care. Aim 3: Explore baseline moderators to elucidate for whom PS-Stand Down (vs. app only) is most beneficial.
In a 3-group RCT at the Palo Alto and Syracuse VAs, 274 Veteran primary patients who screen positive for hazardous drinking, received a brief intervention following a positive screen, and are not currently in alcohol use treatment will complete a baseline interview, be randomized to either (i) UC, (ii) UC plus Stand Down, or (iii) UC plus PS-Stand Down (four phone sessions with a Peer over 8 weeks to enhance app engagement), and be re-interviewed at 8, 20, and 32 weeks. For Aim 2, the CFIR framework will guide key informant interviews with 12 patients and 12 PACT providers from each site.

研究组 & 干预措施
Usual Care
All patients, regardless of condition, will have access to usual care for hazardous drinking in primary care. In this setting, usual care entails a spectrum of alcohol-related services including annual screening for hazardous drinking, brief intervention following a positive screen (advice from a provider to reduce their drinking), and referral (as needed) to specialty AUD treatment.
干预措施: Stand Down app (Behavioral)

干预措施: Usual Care (Other)
UC + Stand Down app (app only)
Patients in this condition will receive Usual Care (UC) and be provided a unique code and password to access Stand Down. The app is based on principles of motivational enhancement and cognitive-behavioral therapies and comprises 7 modules organized around 4 goals: 7 modules organized around 4 goals: (i) Enhance awareness of drinking patterns (assessment and personalized feedback), (ii) Establish and monitor progress towards drinking goal - i.e., moderation or abstinence, (iii) Manage cravings and other problems using in-the-moment tools, and (iv) Connect users with other types of support. App usage will be tracked by the research team for the duration of the study (32 weeks).

UC + Peer-Supported Stand Down (PS-Stand Down)
Patients assigned to this condition will receive UC and access to Stand Down, plus four phone sessions from a Peer over 8 weeks. Sessions will be bi-weekly, approximately 15-30 minutes in length, and focus on enhancing patients' engagement with the app.
