Experiences with a computer information system at the 2nd Department of Obstetrics and Gynaecology, University of Vienna Medical School are reported. The data input is done via video-terminals located at different places in the department. Included are anamnestic data, results of physical examinations, pelvic examinations and laboratory findings and data concerning the course of delivery. The print-out of the stored data replaces the conventional charts. The advantages of this information system are: 1. The support of the clinical routine work by a more accurate and systematic documentation; 2. a comprehensive compiling of the patients data; 3. all stored data are readily available for scientific evaluation.
