Correlation of Functional Capacity and Disease Severity Indices with Quality of Life in Patients with Chronic Obstructive Pulmonary Disease
Journal Title: International Journal of Health Sciences and Research - Year 2017, Vol 7, Issue 11
Abstract
Background: Chronic Obstructive Pulmonary Disease (COPD) reduces exercise capacity which in turn restricts patient’s ability to carry out daily activities and affects Quality Of Life (QOL). Six minute walk test is a simple measure to assess functional capacity which can be an indirect measure of quality of life. There is a paucity of literature on correlation of six minute walked distance (6MWD) with quality of life in Indian scenario hence need for present study. Methodology: This was a tertiary care hospital based Observational study with an aim to find correlation between functional capacity and QOL in patients with COPD. Spirometry-confirmed COPD GOLD category I-IV patients of 5 years or more disease duration, in the age group of 50-70 years, either gender were included. The study factors were six minute walked distance and QOL questionnaires (SGRQ-C, SF 12, and CAT). The data was analysed using Pearson’s correlation. Results: A total of 30 subjects were enrolled and moderate correlation was observed between 6MWD and QoL scores SF-12 and CAT, (r=0.442 and -0.410) respectively, with a p value < 0.05. The disease severity as assessed by mMRC dyspnoea scale and BODE score showed moderate correlation with 6MWD (r=-0.559 and -0.537respectively, with a p value <0.002). Conclusion: A moderate correlation exists between functional capacity and QOL in patients with varying degree of COPD. The 6 MWT may be good test to reflect the health-related QOL in COPD patients.
