title: [Expert systems for medicine--functions and developments].
abstract: Medical knowledge doubles every five years. Electronic media are necessary to manage these volumes. "Multimedia" and "information highway" are buzz-words and also concern medicine. Medical informatics tries to build a bridge between medical research which generates knowledge and daily practice in hospitals, ambulatory care and public services. Knowledge is used in different representations for multiple purposes and functions. Expert systems are mostly designed to fulfil certain functions and to support routine clinical practice. This paper tries to point out some important functions and to explain the capabilities by means of two example systems which can be used in several medical units. The main problem in using expert systems is, besides the quality of knowledge, the availability of patient data. For this reason the existence of an electronic patient record is another area which will be described in this paper. Expert systems are specialised medical information systems and have to fulfil the same success criteria as all the other systems, e.g. the integration into the daily routine as a trusted tool.
