A multicenter family practitioners’ research on Chronic Obstructive Pulmonary Disease screening using the COPD Assessment Test

Abstract

CAT is a reliable questionnaire and there is an apparent relationship between the total CAT scores and COPD. However, CAT's ability to screen COPD is limited since it may miss the symptom-free cases.

Evaluating the Effectiveness of the COPD Assessment Test (CAT) in Screening for Chronic Obstructive Pulmonary Disease

“…In addition, significantly negative correlations were found between the total CAT score and lung function parameters, namely FEV1, FVC, and FEV1/FVC ratio. Similar results have been documented in the scientific literature, 34 indicating that high CAT scores reflect a significant deterioration in lung function.…”

“…However, these results are better than those obtained by Demirci et al in Turkey, who reported a sensitivity, specificity, positive predictive value, and negative predictive value, respectively, of 66.67%, 75.15%, 10.53% and 98.09%. 34 Taken together, our results indicate that the Moroccan Arabic dialect version of the CAT shows a very good performance in detecting cases of COPD and could be used as a promising alternative to spirometry. Indeed, health care units are rarely equipped with spirometers.…”

Decreased handgrip strength can predict lung function impairment in male workers: a cross sectional study

“…The total CAT score is reported to have a significant association with a diagnosis of COPD [23,24]. The CAT is suggested to be useful for screening respiratory health even in an unselected population, and a significant negative correlation between the CAT score and FEV1, FVC, and the FEV/FVC ratio has been reported in the literature [22,25]. In our study, the CAT score was significantly higher in those with lung function impairment than in those without.…”
