The NIH-funded i2b2 tool provides an easy-to-use, self-service method for UW researchers to query the UW Health Enterprise Data Warehouse (EDW) to learn: “Does the EDW contain a group or cohort of patients who all have certain characteristics?” i2b2 contains search criteria related to cancer cases, demographics, diagnostic codes (ICD9 and ICD10), laboratory results, medications, and procedure (CPT) codes.


  • An easily understood database schema.
  • Release under an open-source license.
  • The existence of an organized users group to share information and applications.
  • The potential for translational research through collaboration and federated queries across other i2b2 institutions.
