Objective: The Present study is aimed to correlate spirometry with COPD Assessment Test (CAT) score so that later can be utilized in resource limited settings where spirometry is not available. Methods: Patients attending medicine OPD already diagnosed with COPD, not in the phase of acute exacerbation were included. Their CAT score was noted and spirometry was done during their visit. Results: Out of total 200 patients, 163 (81.5%) were males and 37(18.5%) were females and their mean age was 61 years. The mean CAT score was 22.01, mean FEV1 (%pred) was 76% and the mean FVC (%pred) was 85%. This study shows a highly negative correlation between CAT score and FEV1 %pred. (r= -0.96) and between CAT score and FVC %pred. (r= -0.80) which are highly significant (p<0.0001). Conclusion: With the decrease in COPD patients FEV1 and FVC the CAT score increases. CAT score can be utilized to assess severity of COPD even in remote areas where there is no facility for Pulmonary Function Testing.
Key words: COPD, Spirometry, CAT Score.
