BACKGROUND: Frailty represents a state of risk in which a relatively small stressor results in a disproportionate decline in health status. This study aims to determine the prevalence of frailty among patients with COPD in the Indian population and its associated risk factors.
METHODS: A descriptive cross-sectional study was conducted in 150 COPD patients. Frailty was assessed using the frailty phenotype method.
RESULTS: The mean age (SD) of the study population was 60.59 (5.9) years with 88.67% males and 53.33% ex-smokers. The prevalence of frailty was 51.33% (n = 77). Most of the frail patients belonged to GOLD group D (66.23%) (P < 0.0001). Post-bronchodilator FEV1(%) was lowest in the frail group (40 [36-47]%) (P < 0.0001). Risk of frailty significantly correlated with smoking pack years (1.036; 1.001-1.074), history of 1 exacerbation in last year (6.810; 2.036-22.779), post-bronchodilator FVC(%) (0.955; 0.926-0.985), post-bronchodilator FEV1(%) (0.940; 0.913-0.968), distance covered in 6-minute walk test [0.975; 0.965-0.986] and dyspnoea severity [1.044; 1.024-1.063]. In multivariate regression, 6-minute walk distance and GOLD group B were the independent predictors of frailty in COPD.
CONCLUSION: The prevalence of frailty in Indian patients with COPD was 51.33%. Six-minute walk distance is an important predictor of frailty. Early identification of frailty will lead to prompt intervention and rehabilitation.
