Modeling economic aspects of hospital information systems to give decision support for strategic information management.
Information systems require strategic planning in order to adapt their functionality and quality to the needs of health care organizations. Next to effectivity, cost efficiency in supplying and operating information systems is a particular objective. Hospital information systems with their technical infrastructure, their application systems and the hereby supported business functions can be described with the help of the meta model 3LGM2 and the 3LGM2 tool. The meta model and the 3LGM2 tool are extended by a generic approach to show supply and operation cost for all components of the information system and for the cost calculation between these components. This leads to the fact that all executives in hospitals are enabled to get the cost transparent which were caused by the support of the functions by the information system. The effects of planned extensions and modification of the information system can be analyzed in term of cost. In a prototypical modelling, the information system of a hospital of regular standards has been evaluated in nearly all its components and cost. An evaluation could show that information managers and executives are now delivered relevant cost information for planning, operating and control of information systems.
