Cohort Discovery

The Cohort Discovery Tool is an easy to use self-service, web-based tool used by OHSU researchers to discover patient cohorts from Epic data for preparatory to research purposes. With Cohort Discovery, investigators can rapidly search the medical records of over 2.5 million patients to obtain counts of patients meeting inclusion/exclusion criteria they specify for tasks such as feasibility studies, patient recruitment planning, and pre-IRB study planning. Cohort Discovery utilizes open-source software funded by an NIH cooperative agreement with Partners HealthCare System through the National Center for Biomedical Computing (NCBC) program called i2b2 (Informatics for Integrating Biology and the Bedside).

The tool allows users to ask research questions and get a preliminary count result. Users can select search terms from familiar taxonomies like Demographics, Diagnoses, Medications, Procedures, and Laboratories. After an initial training session which demonstrates it’s ease of use, the user can access the Cohort Discovery Tool when convenient and as needed. These queries can be saved for future use or to be shared with collaborators. Patient sets can be extracted from these saved queries with proper IRB approval.
