UC Health Data Warehouse (UCHDW)

The University of California Health System, with 18 health professional schools, six medical centers, and 10 hospitals, has built a secure central data warehouse for operational improvement, promotion of quality patient care, and to enable the next generation of clinical research. The UCHDW currently contains data on 8.7 million patients seen at a UC facility since 2012. These patients received care in approximately 378 million encounters. In those encounters, UCH conducted over 1 billion procedures, ordered or prescribed more than 1.3 billion medications, made more than 5.2 billion vital signs and test result measurements, including 35,000 sequenced cancer genomes, and assigned more than 1.1 billion diagnosis codes. Over 800,000 of these patients receive primary care through UCH. 

This data warehouse is used to construct several secure web-based dashboards, enabling strategic and operational leaders and clinical directors to see and compare current healthcare quality and costs across the University of California. De-identification of the data has already been completed to enable clinical research projects, under guidance from UC campus institutional review boards, privacy and compliance officers, and information security officers. This data is stored in the OMOP open vendor-neutral data model, enabling a wide range of software tools and computational methods to be used consistently with other state and national efforts. This comprehensive view of UC-wide health data is utilized for comparative analysis to drive population health studies and improve the delivery of patient care across the state of California.
