Telemedical ILOG listeners: Information logistics processing of telemedical values using CEP and HL7

Optimal healthcare supply today relies extensively on the usage of technology to reduce the emerging costs and ensure high quality standards. Especially telemedicine, as a technology that offers the chance to optimize medical data transfer, is regarded as the promising strategy. As a result of the all-encompassing interconnection of healthcare sources, the actors like physicians are confronted with a growing amount of information, also known as information overload. Therefore we propose a new approach, according to the principles of information logistics (ILOG). Based upon complex event processing (CEP) we investigated the concept of Telemedical ILOG Listener (TIL) to process telemedical events in a very modular way. A telemedical event includes the medical data, attributes necessary for C EP and attributes to represent the dimension of ILOG. To standardize the representation of telemedical events we introduce the HL7 Telemedical Event Format.
