title: Challenges in implementing a knowledge editor for the Arden Syntax: knowledge base maintenance and standardization of database linkages.
abstract: BACKGROUND
  Incorporation of research findings into clinical practice lags behind their dissemination in the medical literature. Arden Syntax is a standard that could be used to encode evidence in a clinical decision support system (CDSS). However, dissemination of knowledge is hampered by lack of standard linkages to clinical databases.
  
  
  OBJECTIVE
  To create a knowledge editor that facilitates transfer of knowledge from the medical literature to clinical practice via a CDSS.
  
  
  METHODS
  Using a Web browser-based application, we implemented linkages to MEDLINE to permit queries on demand and registration of queries to be executed periodically, with results copied into Arden Medical Logic Modules (MLMs). To facilitate standardization of MLMs, database linkages are encoded using emerging HL7 standards such as a data model (virtual medical record).
  
  
  CONCLUSIONS
  A Web-based application can facilitate transfer of knowledge into clinical practice and knowledge base maintenance through periodic queries and deployment of standards for knowledge representation.
