The UF Health Integrated Data Repository (IDR) was created to serve as a common source of information to be used by clinicians, executives, researchers and educators.  The IDR enables new research discoveries as well as patient care quality and safety improvements through a continuous cycle of information flows between our clinical enterprise and research community. In its simplest form, a data repository is a collection of disparate data organized in a manner that lends itself to understanding relationships between data elements to answer questions.

What data are in the IDR?
The UF Health IDR currently consists of a Clinical Data Warehouse (CDW) that aggregates data from the various clinical and administrative information systems, including the Epic EMR. The CDW contains demographics, inpatient and outpatient clinical encounter data, diagnoses, procedures, lab results, medications, select nursing assessments, co-morbidity measures and select perioperative anesthesia information system data. The CDW data contains “Fully Identified Data” and is fundamental to institutional business processes and secured per UF&Shands policies.

Who developed the IDR?
The UF Health IDR Team is a multi-disciplinary group comprised of members from Shands Decision and Support Services (DSS), AHC IT, AHC faculty, IRB and the Clinical and Translational Science Institute (CTSI). The IDR Team was formed to develop and implement tools that increase access to institutional data, in a secure and HIPAA-compliant environment, for research, clinical and educational activities.

How can the IDR be used for research?
While the IDR’s CDW cannot be directly accessed for research, a HIPAA-compliant "Limited Data Set" that replicates data from the CDW (with identifiers removed) has been approved for faculty researchers to query for the purposes of identifying cohort counts as they prepare grant proposals, plan clinical trials, write IRB protocols and conduct other preparatory research activities. Researchers can run these queries using UF&Shands i2b2, a Web-based query and analysis tool. After using i2b2 to determine cohort counts and answer similar research feasibility questions, researchers can apply for IRB approval to obtain more extensive data from the CDW. With IRB approval, the IDR Team will act as an “Honest Broker” to provide a research data set, which may be used for various research purposes ranging from answering additional study feasibility questions to conducting complete analyses for retrospective studies.

How can the IDR be used for clinical or educational activities?
The IDR Team is currently planning and developing new uses of the IDR to support clinical and educational activities. The Team is open to new ideas from the UF Health community on how this growing resource can be utilized.
