<p>Assessment timeline for patient participants.</p>

Secondary effectiveness measures include time to first post-discharge follow-up visit, substance use patterns, and acute care utilization (e.g., hospital readmissions). The IntACT study will also enroll 20 clinicians from hospital and outpatient settings who interact with IntACT while providing patient care to provide input on intervention feasibility, appropriateness, and acceptability. Study design and procedural elements will also be assessed for feasibility and acceptability.</p> <p>Discussion</p><p>Identifying promising interventions to support transitions to follow-up SUD and medical care following hospitalization is imperative to increase SUD treatment access and improve care quality.

The IntACT pilot study evaluates the feasibility of a novel, potentially scalable team-based care transition intervention, gathering implementation data from both patients and clinicians who are exposed to the intervention. The results of this pilot study will inform intervention refinement for a future fully-powered clinical trial, as well as other implementation and research efforts supporting care transitions for people with SUD.</p> <p>Trial registration</p><p>Clinicaltrials.gov <a href="clinicaltrials.gov/ct2/show/NCT07575373" target="_blank">NCT07575373</a></p></div>
