Guide to using HERON

HERON  (Healthcare Enterprise Repository for Ontological Narration) is a search discovery tool that allows KUMC faculty members to search de-identified data from various hospital and medical center sources that include but are not limited to:

  • Epic/O2 (the hospital electronic medical record)
  • IDX (the clinical billing system)
  • KU Hospital Cancer Registry
  • KU Biospecimen Repository
  • REDCap (selected projects)
  • Social Security Death Index
  • University HealthSystem Consortium (Quality Measure Data)

By combining the various data sources, researchers can look at the data in new ways not available when viewing data in one source at a time. The following videos are intended to give patients/stakeholders an idea of how their data will be used for research and what types of people will have access to it.
