Specifying workflow process requirements for an emergency medical service.

Recent trends in healthcare delivery have led to a gradual shift in the conceptualisation of healthcare information systems towards supporting healthcare processes in a more direct way. The move towards integrated and managed care, which requires designing healthcare processes around patient needs and incorporating efficiency considerations has led to an increased interest in process-oriented healthcare information systems based on workflow technology. This means to actively deliver the tasks to be performed to the right persons at the right time with the necessary information and the application functions needed. Moreover, workflow technology promotes a component-oriented development whereby the process logic is separated from application logic. This paper presents an approach to capturing process logic requirements for healthcare workflow systems with a view to design a system that is easily adjustable to process changes and to evolving organizational structures at a reasonable cost.
