Evaluation of SNOMED CT as a Reference Terminology for Standardized Data Queries in the Arden Syntax

CONTEXT Arden Syntax is a standard that encodes knowledge as Medical Logic Modules (MLMs) but lacks a standard query data model and terminology. OBJECTIVE Assess to what extent SNOMED CT can represent MLM query data elements. METHOD 340 MLMs containing 3268 queries were examined. RESULT SNOMED can be used to represent all data elements except for clinical decision support system terms such as "alert." CONCLUSION SNOMED CT adequately represents data queried using the Arden Syntax.
