Kopplungsstrategien für Anwendungssysteme im Krankenhaus

The realization of specific coupling strategies and integration techniques is discussed exem-plarily for a university hospital, the Universitätsklinikum Leipzig (UKL) in Germany. The integration of the central patient management system serving the administrative department with the clinical workplace systems serving hospital wards is presented. We analyse the integration with respect to the underlying theoretical conceptions and discuss information management issues for deployment and maintenance of the overall IT infrastructure. This paper presents the pros and cons of synchronous and asynchronous patient data replication, the practical experience with the deployment of a communication server, and the experience with using an RFC interface, a proprietary interface to the enterprise resource planning system SAP R/3. Both, organizational and technical issues are addressed in this context.
