A Process Model Basis for Evolving Hospital Information Systems

Hospitals often invest significant resources in the development of large and complex information systems that must be modified and extended to respond to changing requirements and to exploit the capabilities offered by modern technologies. A disciplined approach of managing the evolution of hospital information systems is then required so that to meet the increasing demands for effective and efficient use of scarce resources. This paper takes a process oriented view of the hospital and presents an approach based on hospital process modeling which aims at assessing the current status of computer support within a hospital and at identifying new opportunities for automation. The approach is illustrated by an example taken from a major Greek hospital.
