This page also provides an overview of external health data research resources. Honest Broker Data Request To request UCI Health electronic health records (EHR) data for quality improvement projects or according to IRB-approved research protocols, submit a Honest Broker Data Request. For inquiries, please email Andrea Hwang at ychwang@hs.uci.edu. Self-Service Research Data Warehouses (RDW) Limited Data Set (LDS) OMOP (Observational Medical Outcomes Partnership) Research Data Warehouse (RDW) Contains the majority of structured EHR data from UCI Health Can be used for research purposes without additional administrative or research ethics approval, provided that adequate data protection procedures are in place. For more information, visit the Self-Service RDW webpage. Any UC Irvine employee or student can request access by sending an email to ori@uci.edu with the signed and attached LDS OMOP Data Use Agreement. For students, the faculty supervisor’s signature must be obtained. University of California Health Data Warehouse (UCHDW) UCHDW is a UC-wide data asset created to enhance operational improvements, promote quality patient care, and enable the next generation of clinical and translational research. It aggregates EHR data from the six UC academic health centers: UC Davis, UC Irvine, UCLA, UC Riverside, UC San Diego and UC San Francisco. It also includes claims data from the UC self-funded health plans, as well as from external sources including Vizient and the California Department of Health Care Access and Information (HCAI), formerly the Office of Statewide Health Planning and Development (OSHPD). The LDS version of UCHDW is available for research reuse without requiring additional IRB approval. Currently, it contains only structured data; de-identified free-text notes are being added and are expected to be available for research reuse in late 2026. To request an account, you must first have access to UC Irvine's local LDS OMOP RDW and have used it for at least a month. Then you can email ori@uci.edu. Research Data Sharing Networks TriNetX TriNetX is a commercial data sharing platform that allows cohort building and aggregate-level analyses with data contributed by a global network of 100+ participating institutions. UC Irvine researchers can use TriNetX as a local cohort discovery tool to construct patient cohorts using UCI Health data. They can also use TriNetX to construct global cohorts and request patient-level data in a de-identified or LDS fashion from TriNetX's Research Network. To request an account, email ori@uci.edu. Visit the TriNetX website. Epic Cosmos Cosmos is a dataset created in collaboration with a community of health systems using Epic and is designed to improve patient care. By combining their data, participating organizations and Epic can make new discoveries to advance medicine. Cosmos also powers tools at the point of care, providing clinicians with insights tailored to the patient in front of them. Submit a Cosmos Basic Access Request. For more information, visit the Epic Cosmos website. NIH All of Us Research Program The NIH All of Us Research Program is part of an effort to advance individualized health care by enrolling one million or more participants to contribute their health data over several years. The program aims to reflect the diversity of the U.S. and to include participants from groups that have been underrepresented in past health research. All of Us is developing custom tools and software to help researchers analyze participant data while keeping information secure. UC Irvine researchers can apply for free accounts to access the data through the NIH All of Us Research Hub. NIH National Clinical Cohort Collaborative (N3C) N3C is a collaboration among the Clinical and Translational Science Awards (CTSA) Program hubs, distributed clinical data networks (PCORnet, OHDSI, ACT, TriNetX), and other partner organizations, with overall stewardship by NIH's National Center for Advancing Translational Sciences (NCATS). It aims to improve the efficiency and accessibility of analyses with COVID-19 clinical data, expand our ability to analyze and understand COVID, and demonstrate a novel approach for collaborative data sharing. UC Irvine researchers can apply for free accounts to access the data. PCORnet® PCORnet® is a national resource, funded by PCORI®, that enables insights from high-quality health data, patient partnership and research expertise to deliver fast, trustworthy answers that advance health outcomes. Visit the PCORnet® website. More Information Visit the ICTS IPH Office of Research Information website. Contact the Office of Research Information at ori@uci.edu.
