USC, CHLA and DHS research teams can use the research data warehouse for study planning (feasibility assessments, power analyses) through their respective i2b2 portals. The self-service website allows researchers to find the number of patients at either CHLA, Keck, or DHS (depending on their affiliation) that meet study inclusion and exclusion criteria. With the help of the CRI team, users can also extract identifiable patient information for screening or recruitment purposes with the proper IRB approval to do so. Once the warehouse data has been validated for quality, research teams will be able to perform large-scale analyses on the data already existing in the warehouse (e.g., epidemiology studies).
Self-Service Data Requests
Using i2b2 users can search health system data for de-identified counts of patients who meet certain inclusion and exclusion criteria (i.e., cohort discovery). The search tool is accessible via a web browser and is self-service.
How to get access
USC researchers are required to complete (1) Human Subjects Training and (2) HIPAA training. Once complete, and reflecting in your iStar profile, please email email@example.com requesting an account and access to i2b2. Please note: a USC Keck-secured Internet network is required to access the application.
