Overview
• Cohort size es.ma.on – UC-‐ReX, LADR
• Data collec.on and data set management – REDCap
• EHR data access – Recruitment – Clinical data export
• “Big” data
UC Research eXchange (UC-‐ReX)
• Trials oIen fail to meet recruitment targets – Technology is needed to find eligible pa.ents
• UC Health System – 5 AMCs, 10 hospitals – 144,000 admissions, 290,000 ER visits / year – 3.9 million ambulatory visits / year – 50% of all transplants in California
• UC-‐ReX Vision Enable researchers to query clinical data from all UC Health campuses under a cross-‐ins:tu:onal IRB approval process
