Under the sponsorship and in cooperation with the Bundesversicherungsanstalt für Angestellte (BfA) in Berlin and the Verband Deutscher Rentenversicherungsträger in Frankfurt, a method for computer-aided classification of severity grades for chronic bronchitis was developed. The purpose of classification into severity grades is to ease the assessment of chronic diseases together with their combinations and to make comparisons possible. This allows derivation of admission criteria for rehabilitational therapy which are suited to computerized processing. Using standardised severity grades permits better evaluation of the effectivity of in-patient care and monitoring the course and/or result of the treatment. Computer-aided determination of severity grades is also feasible in mass-screening programs of out-patient clinics, health services and health insurances as also in preventive care and epidemiological studies. The objective of this project was to reproduce by computer the severity grade estimation as made by a physician from symptoms characterising a clinical picture and to test this method on routine sample material.
