Stanford Medicine's Research Participation services has developed the Participant Engagement Platform (PEP) as a way of offering and managing "honest broker" outreach, such as Direct Email and Epic MyChart. The Research Participation team (honest broker) sends the study invitation to potential participants (identified via EHR cohort search) on behalf of the study team. Only when a potential participant expresses interest, does the Research Participation team pass on their contact info to the study team for follow-up. This is an exciting way to scale recruitment to engage more participants, while protecting patient privacy and reducing study team burden. PEP "slices" the cohort into best outreach channels: Direct Email, Epic MyChart, and Postal Mail/Phone Calls, and tracks out-opts and enrollment metrics. Stanford welcomes feedback and collaboration on this approach to enhancing study recruitment.
