Clinical Data Warehouse
What is i2b2?i2b2 is a project sponsored by the NIH Roadmap National Centers for Biomedical Computing. i2b2 software is the backbone of our CDW and serves two important purposes:
- Support de-identified browsing of patient data to allow easy identification of patient cohorts
- Allow for creation of limited sets of patient data ("Data Marts"), containing only the data needed for a particular research project.
Together, these tasks promote the rapid development of research projects while protecting Personal Health Information.
What information is available?Currently information is available from the UT Physician's outpatient practice (Allscripts), UT Physician's billing database (IDX), UT Dental Branch's billing and imaging data (AXIUM), and de-identified data from several Memorial Hermann Hospital sources.
Process for Data AccessResearchers interested in using CDW data for a clinical study will first need to complete a Request For Data form. The request will be sent to the CCTS Technology Manager for review; if the request is research oriented and involves PHI, IRB approval will be needed. After approval, the CCTS technology team will begin processing the data request, communicating preliminary results to the researcher(s) to facilitate data quality and validation assessments. The CCTS IT Staff provide follow-up support to researchers on issues such as data management and use.
