    24. 17 Mar 06 Northrop Grumman Private / Proprietary Level I Terminology Services Bureau Advantages Reusability LOINC Laboratory Content integrated into TSB for MEDCIN flowsheet implementation LOINC content is being used for AHLTA Clinical Reminder Notification LOINC content is being reused for CliniComp Monitoring Device data integration Ease of maintenance Central mapping repository versus distributed, redundant hard code and data tables.

    25. 17 Mar 06 Northrop Grumman Private / Proprietary Level I Terminology Services Bureau Challenges Proprietary content Source terminology issues Inconsistent use of terminology Task specific structure of terminologies. Context dependency Rules based mapping The content of several local fields determine concept to be mapped to core ontology Systolic blood pressure in the left arm while seated Run time implementation One to one mapping Rules assisted information translation Deep understanding of source terminologies Map modifiers with core terms. Deep understanding of source terminologies Map modifiers with core terms.

    26. 17 Mar 06 Northrop Grumman Private / Proprietary Level I Use Case: Lab Flow Sheet Goal: Given diagnosis from MEDCIN show all related lab results for the patient. Issues: Diagnosis is a MEDCIN ID Lab data stored in the CDR using 3M NCIDs CDR does not understand MEDCIN IDs for Lab MEDCIN contains list of LOINC codes associated with each diagnosis Solution: Need to correlate knowledge from MEDCIN and CDR

    27. 17 Mar 06 Northrop Grumman Private / Proprietary Level I Use Case: Lab Flow Sheets - What the Provider Sees Image of docs clicking on the diagnosis. In the encounter problem list. Clicks on the problem and asks for a flow sheet to be displayed for that problem. The system retrieves the flowsheet and displays it.Image of docs clicking on the diagnosis.

    28. 17 Mar 06 Northrop Grumman Private / Proprietary Level I Use Case: Lab Flow Sheet - How it is technically done

    29. 17 Mar 06 Northrop Grumman Private / Proprietary Level I Planned and Future Uses of TSB Encourage use of TSB for all integration tasks Eliminate custom point-to-point mappings Map once use many times Lab flow sheet project in progress Allow provider to retrieve pertinent lab results for specific problem Interoperability MEDCIN and AHLTA CDR Interoperability between PKC, MEDCIN, and CDR Pre-populate PKC coupler with data already in CDR Pre-populate MEDCIN note with data already in CDR Pre-populate MEDCIN note with data entered into the coupler Use of PKC knowledge engine against CDR and MEDCIN data Use of MEDCIN Diagnosis Prompt against CDR and PKC coupler data

    30. 17 Mar 06 Northrop Grumman Private / Proprietary Level I Planned and Future Uses of TSB (cont.) Educate customers to the advantages of reuse of mediating terminologies Increase number of mediation terminologies and maps.
