[Possibilities for the application of electronic data processing in surgical departments (author's transl)].

The primary precondition for the application of electronic data processing (EDP) are organisational measures including adequate personnel who are needed for preparatory work. Special documentation and coding systems must be introduced for the purpose of data preparation, whereby the size of the EDP equipment (hardware) depends on the problem to be tackled. The EDP programms (software) should be designed in such a way that every doctor is able to operate the EDP equipment even with little knowledge of data processing. Equipment ranges from minicomputers and centralized computer systems to integrated information systems. Whereas today well-designed application models for minicomputers already exist, the integrated information system is still in a development stage.

[Evaluation of nutrition by means of an electronic data processing method for controlling and influencing adequate planning of the structure of the diet].

Electronic data processing is more used also in the analysis, control and surveillance of human nutrition. The present paper deals with a method that permits to evaluate the nutritional structure of all-day canteen feeding by means of a computer program based on the dishes actually delivered by the canteen. Apart from the energy value, the values for animal and vegetable proteins, fats, carbohydrates, calcium, vitamin A and vitamin C have been adopted as criteria. The evaluation was based on a specific scoring system. The results obtained are made available to the respoective institutions in the form of graphs. The qualitative and quantitative effects produced by this method of evaluation have been studied in 10 selected canteens during a period of 3 years.

[Experience in application of electronic data processing in routine medical microbiology (author's transl)].

Experiences in a two years application of electronic data processing in medical routine microbiology are reported. Optical mark reader forms serve as request forms as well as workprotocol. On the left two thirds of these forms (Fig. 1 and 2) the patients data including clinical statements, and the kind of specimen to be investigated (sputum, smear etc.) as well as results not essential for the printout of laboratory reports are filled in. On the right third of the optical mark reader form, in which area the Bell & Howell document reader can read pencil marks, the patients identification number, the tests requested and all results are marked right at the work bench. As shown in the flow diagram (Fig. 3) after completion of the investigation the date on the mark reader forms are read mechanically and the test results are printed (Fig. 5) by means of the computer. In addition, the data processing system, which proved to be very flexible, performs all necessary types of administrative work as filing of laboratory data in a coded form on cards for permanent storage (Fig. 7) statistics and the printout of bills (Fig. 6). The processing of routine microbiology date is achieved by a Siemens DVA 404/3 (64 kbt) connected for magnetic disc device (2993 Mio bytes), and a line printer (60,000 lines per hour) and dialog display monitors, which are used simultaneously for the on line and off line handling of all the data in clinical chemistry-, serology- and hematology-departments of the same institute.

[Electronic data processing of liver scintigrams in chronic hepatitis (author's transl)].

Following administration of 150 muCi of colloidal 198Au numerical scintigrams of the liver and the spleen were obtained in about 200 patients with various forms of chronic hepatitis or with liver cirrhosis as well as in 24 control persons. The data so obtained were electronically processed and the relative activities of the liver, the spleen and both liver lobes compared. Differences of diagnostic value were observed between the various stages of chronic hepatitis.
