Abstract
- Introduction: Chronic obstructive pulmonary disease (COPD) is highly prevalent and underdiagnosed worldwide. The validity and reliability of COPD Population Screening (COPD-PS) questionnaire are not properly known in a large-sample Chinese population. Methods: This is a national multicenter prospective study that enrolled 1,824 outpatients from 12 hospital sites in China. Scores of the Chinese version of COPD-PS questionnaire, demographic data, and clinical information were collected. The validity and the test-retest reliability were evaluated. Results: 1,824 participants were involved in this study, and 404 (22.1%) were diagnosed with COPD. The overall area under the curve (AUC) of the receiver operating characteristic (ROC) for COPD-PS questionnaire was 0.761 (95% CI: 0.734–0.787). A cut-off point of 4 was recommended, corresponding to a sensitivity of 74.50% and a specificity of 64.37%. The COPD-PS questionnaire showed an overall Pearson's correlation of 0.88. Conclusions: The COPD-PS questionnaire can be used in screening COPD patients from the general Chinese population with respiratory symptoms. [ABSTRACT FROM AUTHOR]
