The Participant Recruitment Service at UCSF is preparing for launch with a soft launch phase involving developing recruitment materials, piloting recruitment services for 4 studies, creating a participant registry database, and conducting passive recruitment from the Integrated Data Repository database. The PRS aims to centralize recruitment efforts and address challenges like limited coordinator time, uncoordinated multi-site efforts, and lack of diversity in clinical trials. The soft launch will test recruitment materials, registry, and services to help enroll more research participants.
