What this trial studies

This clinical trial evaluates a comprehensive intervention for moderate to severe Alcohol Use Disorder (AUD) initiated in the Emergency Department (ED). It combines Screening, Brief Intervention, and Referral to Treatment (SBIRT) with medications like naltrexone and gabapentin to improve treatment engagement and reduce heavy drinking days. Participants will be screened for AUD and randomized to receive either medication treatment or standard care, with follow-up assessments conducted 30 days post-ED visit. This approach aims to enhance access to AUD treatment for individuals frequently seeking care in the ED.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 80 diagnosed with moderate to severe Alcohol Use Disorder who are willing to comply with study procedures.

Not a fit: Patients with current opioid use disorder or those requiring opioid pain medications during the study period may not benefit from this intervention.

Why it matters

Potential benefit: If successful, this intervention could significantly increase treatment participation rates for individuals with Alcohol Use Disorder.

How similar studies have performed: While this specific approach is novel, similar ED-based interventions for other conditions have shown success in improving treatment engagement.
