To increase the quality and decrease costs of medical care provision, hospitals apply clinical pathways \ (CPs) to ‘model’ and manage their processes. Conceptual models of CPs should foster communication \ between hospital stakeholders, serve as an instrument for quality assurance and optimisation of resource \ usage, and a foundation for the (re-)design of hospitals’ action and information system (IS). However, \ existing approaches to CPs’ modelling suffer from simplifications and a low level of domain-specific \ semantics. In addition, they focus mainly on processes and neglect other aspects relevant to a comprehensive management of hospitals. We argue that to realise the potential benefits of CPs, a comprehensive modelling method accounting for peculiarities of hospitals’ action system and IS is required. The core of such a method should be a Domain-Specific Modelling Language for CPs presented in this paper.
