Terminology Standards Support Task 1
We performed terminology matching, shaped clinical terminology policies and performed User Acceptance Testing for CTTDM (formerly called Isaac) a terminology authoring tool. In addition we built Detailed Clinical Models (DCMs) called LEGOs based on patient questionnaires. We also developed HL7 international data exchange standards including those for Patient Care. We began two new projects: one to standardize how HL7 handles negation and one to represent Pressure Wounds using DCMs for the CIMI work group.
J P Systems provided medical terminology liaison services to SNOMED International (formerly IHTSDO) for the Observables Project. We monitor and influence terminology standards trends internationally.
The primary purpose of these efforts is establish standardized concepts, terms and their underlying codes for clinical and administrative data in order to: a) enable interoperability among healthcare software systems within and external to VA; and b) enable automation based on such data. Specifically, Clinical Decision Support (CDS) functions and alerting such as drug-allergy or drug-drug interactions can only be achieved by the use of standardized terminology.
