Abstract: Clinical Pathways can be viewed as workflows, comprising an
ordering of activities with associated execution constraints. Workflow models
allow formal representation, analysis and execution of workflows in the
Clinical Pathways. We present a semantic web-based approach where the
domain knowledge and the workflow model are modeled separately as
ontologies, while the Clinical Pathway and the associated workflows are
modeled as the instantiations of these ontologies. Our workflow model is based
on the UML Activity Diagrams and OWL-S service ontology, and the
execution semantics are based on Place/Transition Petri Nets. We demonstrate
our approach by capturing the workflow of the Prostate Cancer Care Pathway.
1. Introduction
Clinical Pathways (CP) aim to coordinate the care process for a specific condition at
the institution level. In essence, CP describe the functional knowledge pertaining to
an institution's clinical practices in terms of time-sensitive and outcome-driven
processes--represented as a combination of plans, tasks, decisions, resources and care
