Clinical Practice Guidelines

Abstract. Computerization of Clinical Practice Guidelines (CPG)
render them to be executable at the point-of-care. In this paper, we
present a knowledge modeling methodology to model the form and
function of CPG in terms of a new CPG ontology that supports CPG
computerization and execution. We developed a CPG ontology, in
OWL using Prot´eg´e, to represent both the structural elements and
the knowledge objects encapsulated in a CPG. We instantiated over
10 different CPG using our CPG ontology, whereby the instantiated
CPG can be executed, with patient data, using a logic-based exe-
cution engine to provide patient-specific recommendations. We also
investigated the dynamic merging of multiple CPG, at the encoding
and execution levels, to handle patient co-morbidities. We evaluated
the CPG ontology by examining its representational efficacy to ade-
quately model the salient constructs of a CPG based on an existing
CPG modeling formalism.
