This study will recruit Emergency Department (ED) patients with moderate to severe alcohol
use disorder (AUD) who are interested in initiating medication assisted treatment (MAT). The
study is split into two phases. The first phase (N=10) will use implementation science
strategies to strengthen existing non-targeted ED based AUD screening program and optimize
feasibility, acceptability, and linkage pathways. The second phase (N=20) will incorporate
lessons learned from phase 1 to initiate ED patients on MAT for AUD in the form of oral
naltrexone. The primary outcome for both phase 1 and phase 2 is engagement in comprehensive
addiction treatment at 14 and 30 days post enrollment.
