Abstract. Clinical Pathways (CP) stipulate an evidence-based patient care
workflow for a specific disease within a localized setting. We present an ontology-
based approach for computerizing CP so that they can be executed at the point-of-
care. We present our CP modeling approach that features the integration of
multiple localized CP to realize a unified disease-specific CP. The execution of the
ontological CP model is achieved by our property abstraction method that assigns
functional behaviors to existing semantic properties to facilitate their execution.
Using our methods we have developed a prostate cancer management system.
Keywords. Clinical Pathway, Decision Support, Ontology, Prostate Cancer
1. Introduction
In Canada, the management of prostate cancer follows an integrated care approach
involving multiple medical disciplines, care settings and health professionals. This
integrated approach demands an effective coordination between family physicians,
urologists, radiation oncologists and nurses to manage the patient's care trajectory. One
possible solution to coordinate the care activities is to subscribe to Clinical Pathways
(CP) as they are evidence-based patient care algorithms/charts that describe the care
