Health service production in the view of medical informatics.

Medical informatics aims to improve the process and the result of health care delivery, both in its theoretical and practical aspects through the application of formal methods and concepts of informatics and the utilization of up-to-date information and communication technology. As part of a theoretical framework this paper deals with the factors of production, the constitutive criteria and the formal aspects of health service production in the view of medical informatics.

The empirical object of medical informatics.

Medical informatics is the science of information processing and the creation of information processing systems in medicine and health care delivery. Its methodological approach is based on the area specific applicability of a multidisciplinary theory of engineering and managing computerized information systems related to its empirical object. This paper gives a systemic view of the health care system, representing the empirical object of medical informatics.

[A factor system for health care service production].

Seen from the viewpoint of economy with particular reference to services, "production" of health care may be regarded as a secondary process of input and output managed by the medical profession by means of a combination of several factors. On the input side we have immaterial and material economic items (production factors) which may be described as a system of factors that are specific to health care providers.

Knowledge of engineering for a medical-history expert system.

Computerized information systems that support medical decision-making are based upon formalized medical knowledge. Therefore, appropriate methods of knowledge engineering are of conspicuous importance. In order to arrive at a medical-history expert system, a target-oriented construction method of knowledge engineering was devised. Beginning with a framework of diagnostic categories, an optimal set of reliable and valid questions were formulated. In this paper, two independently developed general medicine questionnaires prepared by such a method are comparatively presented. It is shown that (a) inspite of a good deal of similarity between the two frames of reference considerable differences exist between the two sets of selected questions, and (b) the valid collection of medical information is limited to diagnostic categories that allow a clear description of medical symptoms.

Towards the morphology of medical information systems.

A review of research and development in the field of medical information systems shows that, on the whole, technical hardware and specific software problems have been the central consideration. Only recently has it been acknowledged that it is necessary to include the formerly neglected specific functional and organizational aspects. In this respect, morphological approaches enable new perspectives to be opened up for the analysis, design and classification of medical information systems.
