A Computer-Aided Learning Model (CALM) was used to recognize the characteristic symptoms of bronchitis by comparing the questionnaire responses of patients with that diagnosis to the questionnaire responses of patient without that diagnosis. The computer printed out a diagnosis profile for bronchitis which consisted of weighting values for each of 3778 questions. This diagnosis profile was used in a subsequent diagnostic trial of new patients. The computer agreed with the clinical diagnosis of bronchitis in 96°/o of cases. The study validates both the questionnaire as a means of eliciting clinically meaningful data and CALM as a basis for a computer diagnosis system.
