Summary

Cardiovascular disease is the leading cause of death among Veterans. Clinical trials are essential for developing better treatments, but Veterans remain underrepresented in these studies due to barriers including limited health literacy, lack of awareness, and mistrust. Current outreach approaches rely on either in-person physician conversations, which are limited by workforce constraints, or mailed letter invitations, which often fail to engage Veterans with limited health literacy. This study tests whether AI-generated video avatars can improve Veteran engagement in cardiovascular clinical trials.

AI-Generated Avatar Videos and Chatbot for Clinical Trial Outreach

They may watch the self-directed tailored video to guide their decision to participate in the parent trial.
