De-identified Clinical Data Repository (DCDR)

Important Note: As of September 1, 2018, the ITHS Biomedical Informatics team will no longer provide services through the De-identified Clinical Data Repository (DCDR) tool. The ITHS DCDR will be replaced by a new tool called, “Leaf,” which has been developed in partnership with UW Medicine.

De-identified Clinical Data Repository (DCDR)

The DCDR is a de-identified data repository that contains a subset of data from various UW Medicine clinical systems. Please see the data dictionary page for details about the data elements contained in the DCDR.

The DCDR is a cohort identification/feasibility estimation tool. The interface to the DCDR is a secure web-based query tool (currently powered by i2b2) that allows researchers to individually query the data.

The tool provides a graphical query interface that allows the definition of criteria and returns an aggregate count or a summary of the patients who meet the criteria. An example query in this interface would be of the form: “Provide me a count of patients 18-34 with a diagnosis of diabetes mellitus, who were discharged live within the past six months.”

Accessing the DCDR

  1. Request DCDR access by filling out the Access Request Form. We will notify you within two business days of your access status.
  2. Once you receive your access approval, go to the DCDR Web Interface to access the tool.
  3. Go through self-directed training modules to learn how to query the DCDR.

Support is accessible through individual or group appointments.
