Telemedical events: Intelligent delivery of telemedical values using CEP and HL7

Today's central issues in the healthcare supply make it imperative to develop new concepts to reduce the emerging costs and ensure high quality standards. Applying ICT and especially telemedicine - technologies that offer the chance to optimize medical data transfer - is regarded as the promising strategy, when developing cost saving concepts. As a result, physicians, as recipients of medical data, are confronted with a growing amount of information. This has to fit seamlessly into the process of information exchange and therefore has to be transported according to the principles of information logistics (ILOG). Therefore the author proposes a new approach based upon complex event processing (CEP), named Telemedical ILOG Listener (TIL). Every telemedical value, like for instance blood-pressure, has to be described as a telemedical event. For this reason in the following the author will describe how to use HL7 V3, a worldwide used standard for medical data exchange, to define a message type which is able to include the medical data, data necessary for CEP and at least data to represent the dimension of ILOG.
