AB Background: COPD assessment test (CAT) is a recently developed questionnaires used for assessing and monitoring chronic obstructive pulmonary disease (COPD). However, the relationship with CAT score and the other clinical parameters of COPD are not well determined yet. In this study, we aimed to investigate if CAT score is associated with the measures of clinical courses such as annual decline of lung function and acute exacerbation of COPD.Methods: We enrolled the patients with COPD, who were followed for more than two years. CAT and St. George Respiratory Questionnaire (SGRQ) were performed and information of clinical parameters of COPD was collected in a retrospective manner.Results: A total of 77 patients with COPD were recruited. CAT score showed a fair correlation with SGRQ score (r=0.429, P<0.001) and FEV1 (r=-0.231, P=0.02). Higher CAT score was significantly associated with more rapid decline of FEV1 over 2 years (P=0.02) and acute exacerbation of COPD (P=0.002)Conclusion: CAT score showed good relationship with various clinical parameters of COPD, including FEV1, acute exacerbation and deterioration of lung function. These findings suggest that CAT reflects various features of COPD and could be used more widely in assessing and monitoring of COPD.
