HERON Delaware upgrade to i2b2 v1.7.03 introduces the Temporal Query Tool which allows you to narrow your search by a series of events. For example:

  • Define a population
    • create a search for males with hypertension and acute myocardial infarction
  • Define events
    • Event 1 is hypertension
    • Event 2 is acute myocardial infarction
  • Define temporal relationships of the events
    • Event 1 happens before event 2 by greater than 1 day
  • Submit the query.
    • Results include the number of male patients who have had at least 1 acute myocardial infarction diagnosis after a hypertension diagnosis.

HERON issues to note due to recent data clean-up by the O2 team:

  • Deceased per Social Security Master Death File decreased due to the removal of certain Social Security Numbers in the EMR. See #2911 for more details.
  • Nursing data decreased. See #2955 for more details.

To learn more about temporal querying in HERON, join the Frontiers Lunch and Learn which meets the 1st and 3rd Tuesdays of each month from 12:00 - 1:30 PM in room 3001D Student Center. Register in advance if possible but drop-ins are welcome.

Any publication that results from a project utilizing HERON should cite grant support (CTSA Award # UL1TR000001).
