Background: Chronic obstructive pulmonary disease (COPD) has a major impact on health status in accordance with disease severity. It is usually assessed by the various quality of life questionnaires. Objectives: The aim of this study is to assess the disease severity and health status in stable patients of COPD using COPD assessment test (CAT) and clinical COPD questionnaire (CCQ) scores and to correlate with BODE index and its components. Methods: One hundred patients of stable COPD were subjected to CAT, CCQ irrespective of the stage of COPD during their visit. BODE index was also calculated. Results: COPD severity status assessed using forced expiratory volume 1% (FeV1%) predicted values correlated significantly with individual scores (CAT and FeV1%; r = −0.67; P < 0.001 and CCQ and FeV1%; r = 0.61; P < 0.001). CAT and CCQ score also correlated significantly (r = 0.84, P < 0.001) and both with the BODE index (r = 0.80; CAT and r = 0.66; CCQ, P < 0.01). Individual components of BODE index significantly correlated with CAT and CCQ scores. Conclusions: The CAT and CCQ have similar psychometric as well physical properties to assess the health status of COPD patients and can be used as a reliable scientific research tool and can be used in clinical practise to study the disease state and plan an appropriate treatment plan. The BODE index which is more objective, correlated well.
