HERON Elk City updates to i2b2 v1.6.07 and includes Ambulatory Nursing Documentation and Orders

The Elk City HERON release includes an upgrade to the i2b2 software version 1.6.07. Width of the Query Tool and Navigate Terms workspaces can be resized by dragging the vertical bar between the areas. Query within query fixed to provide correct patient numbers. We have also incorporated nursing/multidisciplinary flowsheet data from the ambulatory clinics (an additional 20 million facts) as well as procedure orders (from 54 million to 110 million).  For the flowsheet data, check out the "UKP" folder and the "KU AMB" and "KU GEN CARD" subfolders under "KU" in the ontology for many of the new types of data now exposed by HERON for clinic visits.  This release also includes many fixes behind the scenes not visible through the interface.

Note that this month, the Smart Data elements contained within physician notes were not loaded due to a data inconsistency detected by our loading process. We are investigating the root cause but do not want this fairly new data source to delay the release of the database for this month. See ticket 1516 for details.

Beta Disclaimer

We are providing this early access to obtain feedback from you, the research community. While we are actively working on validating the data loaded into the system with hospital and clinic technical staff, there may be problems with our translation of data from our source systems (HospitalEpicSource and ClinicIdxSource) into HERON.

Please email us at if you discover information you believe may be erroneous.

We are actively working on enhancing the types of data included. Stay tuned to our roadmap to track progress toward upcoming releases.

Various Issues Still Apply

Keep in mind the issues noted in the original HERON beta notice, including:

Enhancements and Problems/Defects/Issues Addressed in this Release

multicohort survival analysis plugin
HERON patients seem to age after they die
drag-and-drop entrance criteria, outcome, censor for survival analysis plug-in
Query HERON procedure orders by inpatient/outpatient modifiers
some detailed diagnoses from Epic are hidden under ICD9 leaves
flatten top of UMLS ICD9 Diagnosis hierarchy
Harvest ambulatory nursing flowsheet data
names in HERON "reports" hierarchy are long and redundant
Explosion of diagnosis codes leads to poor performance
