The paper deals with the description of the regions of the use of automatized processing of medical informations; i.e. the basic processes of the information processing referred to patients in the hospital, the information and documentation referred to patients, the information relations between the place demading efficiencies and bringing efficiencies in the medical institution including systems organized in the territory as well as the finding of decisions in medicine. With the description of the individual regions of use are connected considerations of the utility, issuing from the project of the electronic data processing realised at the Medical Academy Dresden. The regions of application described make clear that the tasks of the automatized processing of medical informations extend to the following: Taking over of functions of the description of information and the storage of information, taking over of functions of the comparison of informations and the control of information, taking over of functions of the organisational preparation and the planning of diagnostic and therapeutic courses as well as the taking over of functions of the information integration. It is clearly to be established that the electronic data processing shall not restrict the turning of the physician to the patient, but shall improve and enlarge it. The electronic data processing is a modern means of work which with progressing scientific and technical development medicine needs just as much as other technical procedures and methods.
