Comparison of COPD Assessment Test and Clinical COPD Questionnaire to predict the risk of exacerbation.

ABSTRACT:

Background and objective

Guidelines recommend the use of simple but comprehensive tools such as COPD Assessment Test (CAT) and Clinical COPD Questionnaire (CCQ) to assess health status in COPD patients. We aimed to compare the ability of CAT and CCQ to predict exacerbation in COPD patients.

Methods

We organized a multicenter prospective cohort study that included COPD patients. The relationships between CAT, CCQ, and other clinical measurements were analyzed by correlation analysis, and the impact of CAT and CCQ scores on exacerbation was analyzed by logistic regression analyses and receiver operating characteristic curve.

Results

Among 121 COPD patients, CAT and CCQ score correlated with other symptom measures, lung function and exercise capacity as well. Compared wi
