Epic Data for Research Purposes

OCTRI maintains a repository of Epic data from patients and research subjects.  This valuable resource is known as the Research Data Warehouse (RDW). The RDW provides access to over 2.5 million patient records with 20 million patient encounter records and more than 40,000 data points. Researchers work with OCTRI staff to obtain answers to a variety of research purposes.
  • Cohort discovery (counters) for preparatory to research purposes
  • Deidentified data sets for epidemiological studies 
  • Data sets that identify potential study participants or gather retrospective data on current study participants

The Research Data Warehouse (RDW) contains an enormous amount of linked clinical data and can be queried to answer a broad range of research questions. OCTRI staff can act as your guide through this complex data.


Examples of Research Data Warehouse Usage

  • Assess feasibility for a grant application
    Determine many OHSU Down syndrome patients between 1 and 18 years had a Cardiology Department visit in the last 2 years.
  • Identify potential study participants
    Provide a list of patients who have abnormally high liver function test (ALT and AST) results, are between 18 and 65 years, are currently taking anti-hypertensive medication, and were seen in the last six months by an immunologist at OHSU.
