Abstract. Lately, there have been considerable efforts to computerize Clinical
Practice Guidelines (CPG) so that they can be executed via Clinical Decision
Support Systems (CDSS) at the point of care. We present a Semantic Web
framework to both model and execute the knowledge within a CPG to develop
knowledge-centric CDSS. Our approach entails knowledge modeling through a
synergy between multiple ontologiesi.e. a domain ontology, CPG ontology
and patient ontology. We develop decision-rules based on the ontologies, and
execute them with a proof engine to derive CPG-based patient specific
recommendations. We present a prototype of our CPG-based CDSS to execute
the CPG for Follow-up after Treatment for Breast Cancer.
