BPMN4CP Revised -- Extending BPMN for Multi-perspective Modeling of Clinical Pathways

Clinical Pathways (CPs) can be seen as business processes of hospitals or clinical institutions. Modeling these pathways is an emerging field of research, as it provides promising benefits for systems integration, quality management and documentation. The Business Process Model and Notation (BPMN) provides a range of process-related concepts but naturally lacks in representing specific aspects from the CP domain. Therefore, the BPMN extension BPMN4CP was designed in a previous research project. In accordance with research guidelines from Design Science, the extension ran through an iteration based on its practical application within a telemedical project. Based on several new requirements, the extension was revised regarding to the integration of resources, documents, objectives and quality indicators. These concepts were assigned to particular perspectives and diagrams in order to support model complexity management and provide appropriate diagrams for respective stakeholders. In order to provide a commonly usable extension, these enhancements were implemented as BPMN meta model extension.
