INTRODUCTION: Six-min walk test (6MWT) is easy to use, the least expensive, and a quick measure of physical function and it reflects the capacity to perform our day-to-day activities hence quality of life can be assessed with 6MWT. This study was planned to assess the role of 6MWT in chronic respiratory disease patients and its association with spirometry-based functional grading at a rural tertiary care center of northern India.
MATERIALS AND METHODS: This was a hospital-based cross-sectional study done between December 2019 and July 2021. In this study, 110 patients were included as per inclusion and exclusion criteria. 6MWT and spirometry were conducted as per the American Thoracic Society/European Research Society recommendation using Spiropalm 6MWT and the association between 6MWT and spirometry was assessed.
RESULTS: A total of 110 chronic respiratory disease patients were included in the study. There were 69 (63%) males while 41 (37%) were females. Among study participants, chronic obstructive pulmonary disease patients were the most common 48 (43.6%) patients, followed by asthma 28 (25.5%), posttuberculosis sequelae patients 22 (20%), interstitial lung disease 9 (8.2%), and bronchiectasis 3 (2.7%) patients were found. There was a significant positive correlation of 6-min walk distance (6MWD) and % predicted 6MWD with spirometric parameters, forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC) and there was a significant positive correlation of 6MWD with FEV1% (predicted) also. 6MWD and % predicted 6MWD negatively correlated with FEV1/FVC and association between 6MWD and FEV1/FVC was not statistically significant and between % predicted 6MWD and FEV1/FVC, it was found statistically significant.
CONCLUSION: The 6MWD traveled by chronic respiratory disease patients was significantly lower than the predicted 6MWD and 6MWD correlated with spirometric variables well. Therefore, it can conclude that 6MWT is a useful alternative of spirometry in the management of chronic respiratory disease patients in resource-limited settings.
