Recruitment Feasibility Tools (Cohort Counts)

These self-service tools allow researchers to explore and assess the availability of a patient population using Electronic Health Record data. Users enter EHR-based eligibility criteria and receive patient cohort counts. 

Research Data Browser: you can use the UCSF Research Data Browser (RDB) to determine how many patients at UCSF meet your eligibility criteria. The RDB is a point-and-click browsing tool that allows researchers to explore UCSF patient records de-identified from APeX. The RDB does not require IRB approval and is a free, self-service tool for the UCSF research community. Registration and account activation is required. Visit the Research Data Browser page for more information.

ACT Network: Researchers planning multisite studies can use the ACT Network. ACT is a real-time, open access platform to explore & validate feasibility for clinical studies. It contains over 125 million patient records, and by the end of 2019 will include ~90% of the Clinical and Translational Science Award (CTSA) consortium. Available at no charge, registration required. Learn more and register:
