Clinical research networks help researchers access clinical data across multiple health systems for research projects. UCSF contributes data and helps researchers access multiple clinical research networks.
PCORnet, the National Patient-Centered Clinical Research Network
PCORnet is a national resource, funded by the Patient-Centered Outcomes Research Network. UCSF participates, maintains its data in the PCORnet Common Data Model format, and supports UCSF researchers who want to use the network or participate in PCORnet Studies. Learn more about the network at https://pcornet.org/, and access UCSF’s PCORnet resources by requesting a data extraction consultation and mentioning “PCORnet” in your request.
UC Health Data Warehouse
The University of California Center for Data -driven Insights and Innovation (CDI2) manages a data warehouse with electronic health records data from health systems at UCSF, UC Davis, UC Irvine, UCLA, UC San Diego, and UC Riverside. The data are managed in the OMOP Common Data Model. More information about CDI2 can be found here. To access the UC Health Data Warehouse, request a data extraction consultation, and mention “UC Health Data Warehouse” in your request.
The National COVID Cohort Collaborative Data (N3C)
The NIH/NCATS National COVID Cohort Collaborative (N3C) Data Enclave is a centralized, secure, national clinical data resource that the research community can use to study COVID-19, including potential risk factors, protective factors and long-term health consequences. UCSF participates and provides data to this national resource. Access to N3C is managed by NIH, and it is currently offline, but will be returning according to a post by NIH in December 2025.
