Abstract
A CDSS (Clinical Decision Support System) aiming to support the exploitation of CG (Clinical Guidelines) by HCP (Health Care Practitioners) has been designed, able to consider the available knowledge about the patient’s health stored within the CIS (Clinical Information System), using the CIS native, well-trained functions and ergonomics. Amongst the main methods used, figure rule based decision trees to represent the CG knowledge, concept dictionary bonded to international standard terminological systems for semantic indexing, usage of CIS components as part of the CDSS to ensure the respect of the clinical workflow. The results obtained are threefold: 1) a CG model structure adapted for such CDSS; 2) a semantic interoperability platform populated with SNOMED 3.5 international terminology system between CDSS and Electronic Healthcare Records; 3) a workflow of clinical information systems elements coupled by a rule engine solution allowing authoring CG as decision trees. The semantic interoperability platform is up and running in more than sixty large French healthcare organizations, the CDSS is available for first exploitation experiments.
