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.
