Abstract
AI/RHEUM is a knowledge‐based computer consultant system for the diagnosis of rheumatic diseases. Its diagnostic accuracy was evaluated using information that was supplied by Japanese rheumatologists on 59 patients with connective tissue diseases. The diagnoses of the AI/RHEUM model were in full or partial agreement with those of the Japanese rheumatologists in 54 of 59 cases (92%). Preliminary evaluation of the criteria used by the model to diagnose mixed connective tissue disease showed a sensitivity of 90% and a specificity of 96%.
