Brief summary
The investigators will conduct a study to examine the impact of an alcohol peer-mentor intervention starting in the emergency department (ED) combined with 6 peer booster sessions to reduce hazardous drinking and facilitate primary/specialty care use compared to enhanced usual care. Approximately 450 Veterans with hazardous drinking behaviors will be randomized to one of these two conditions. Follow-up assessments will occur at 3-, 6-, and 12-month post-randomization.
Detailed description
The objective of the study is to conduct a randomized controlled trial to determine the efficacy of an alcohol peer-mentor intervention starting in the ED, combined with a continuing 6-session program of post-ED strengths-based peer mentorship to facilitate reduction in hazardous drinking, and linkage and engagement in primary and/or specialty alcohol treatment services and mental health care, if needed. Project Methods: The study will screen Veterans Affairs (VA) ED patients for hazardous drinking. Those screening positive and who enroll in the study will be randomized to one of two conditions: 1) Alcohol Peer-Mentor (APM) intervention (n=225), or 2) Brief Advice (BA) comparison condition (n=225). Stratified random assignment to conditions will be by sex and presence of AUD (yes/no) defined as a score of 14 for men and 10 for women on the AUDIT. Randomization will proceed in blocks of 10. All participants will also receive written community resource information. Participants randomized to the APM condition will receive peer support to reduce hazardous drinking, and those who meet alcohol use disorder criteria will be coached by the peer and will assist in a warm handoff linkage to addiction treatment.
Interventions
BEHAVIORALAlcohol Peer Mentor Intervention
A Veteran Peer research assistant will have contact with a study participant once in person in the emergency department at enrollment, and up to 6 times after enrollment over the course of 2 months. Participants will receive brief advice from a peer. Brief advice content will be based on strengths-based discussions with participants regarding their drinking and personal goals and preferences. Participants will also receive a resource pamphlet on alcohol and other health issues. Follow-up contact will be made by phone. The content of the follow-up peer intervention will be based on the manual developed by the study team to address strengths-based intervention topics.
BEHAVIORALBrief Advice
Participants will receive brief substance use advice from a non-peer research staff member in the emergency department. Brief advice content will mirror standard care practices currently provided in VHA when a patient endorses hazardous drinking behaviors. Participants will also receive a resource pamphlet on alcohol and other health issues.

Intervention model description
Veteran peer research assistants will deliver alcohol brief advice in the ED and will initiate conversations with the participant for at least 6-sessions over 2 months post-ED visit. Strengths-based discussions will include a combination of scripted and open-ended content to best facilitate reductions in drinking and engagement across severity.
