Objective: To evaluate the effect of Chronic Obstructive Pulmonary Disease (COPD) on health and life with the Chronic Obstructive Pulmonary Disease Assessment Test (CAT) in stable COPD and to measure CAT's practical use. Methods: This is a single-center cross-sectional study of which participants were ≥ 40 years old patients with stable COPD and without any exacerbation in the last one month or reversibility in pulmonary function test (PFT). To evaluate the patients' health status and respiratory functions, we performed CAT, SGRQ, BODE index, PFT, six-minute walking tests (6 MWT). We analyzed the correlations of CAT with the pulmonary function tests, SGRQ score, and BODE index and assessed the internal consistency of CAT, and compared the time consumed for CAT and SGRQ. Results: A total of 100 stable COPD patients were enrolled in the study, 87 patients were male and the mean age was 63,68±7,73. The mean CAT score was 12.05±8.29, and there was no statistically significant difference between the test and re-test CAT score (p>0.05). The mean SGRQ score was 37.75 and the mean BODE index was 3.2 and CAT correlated positively with both SGRQ and BODE index and negatively with forced expiratory volume in one second (FEV1). CAT was significantly less time-consuming compared to SGRQ (respectively, 4,41±0,39 and 8,21±0,75 minutes, p<0,05). Conclusions: CAT can provide information about the stable COPD patient's healthy life quality and functional status similar to SGRQ and BODE index and consumes less time, thus seems more practical.
