title: Communication and interoperability for serial comparison in continuous health care--the new challenges.
abstract: The evolution of information technology and of telematics and increasing efforts to establish an electronic health record stimulate the development and introduction of new concepts in health care. However, compared to other application areas, e.g., tourism, banking, commerce etc. the use of information technology in health care is still of limited success. In hospitals as well in ambulatory medicine (General Practitioner systems) computers are often only used for administrative purposes. Fully operational Hospital Information Systems (HIS) are rare and often island solutions. The situation is somewhat better for department systems (DIS), e.g., where image analysis, processing of biochemical data or of biosignals is in the clinical focus. Even before we have solved the various problems in health care data processing and management within the "conventional" care institutions new challenges are coming up with concepts of telemedicine for assisted and non-assisted home care for patients with chronic diseases or people at high risk. The major challenges for provision of tele-monitoring and alarming services are improvement of communication and interoperability of devices and care providers. A major obstacle in achieving such goals are lack of standards for devices as well for procedures and a lack of databases with information on "normal" variability of many medical parameters to be monitored by serial comparison in continuous medical care. Some of these aspects will be discussed in more detail.
