This article presents a study to predict the accuracy of the clinical prediction rule for hypersensitivity pneumonitis (HP). 661 patients who were 18 years of age, presented with a pulmonary syndrome that could be HP, did not have stage 1 sarcoidosis or a previous diagnosis of HP, and were not referred for therapeutic evaluation of a known interstitial disease. Logistic regression was used to compare the clinical characteristics of patients with and without HP for 18 variables. A diagnosis of HP was made on the basis of broncheoalveolar lavage lymphocytosis and bilateral ground-glass or poorly defined centrilobular nodular opacities on high-resolution computed tomography.
