Frailty in Korean patients with chronic obstructive pulmonary disease, using data from the Korea National Health and Nutrition Examination Survey, 2015 and 2016

Abstract

Aim: To describe frailty, to identify its determinants, and to examine how it affected functioning in Korean patients with chronic obstructive pulmonary disease (COPD). This analysis was based on datasets from the Korea National Health and Nutrition Examination Survey (KNHANES). Background: Most of what is known about the prevalence and determinants of frailty in patients with COPD has come from countries other than Korea. Examining this issue with a representative sample of COPD patients in Korea will shed light on frailty in this population. Methods: This cross-sectional study, a secondary data analysis, used datasets from the KNHANES VI (2015) and VII (2016) to understand frailty in 417 patients with COPD (mean age = 65.36; FEV1%predicted value = 78.91). Demographic and clinical data, symptoms, self-rated health, frailty, and functioning were collected in health interviews and health examinations. Descriptive and inferential statistics were used to analyze the data. Results: One hundred forty-eight participants (35.5%) were frail, 156 (37.4%) were pre-frail, and 113 (27.1%) exhibited no frailty. Multivariate logistic regression showed that self-rated health, stage of COPD based on the Global Initiative for Chronic Obstructive Lung Disease, pain/discomfort, and arthritis were significant predictors of frailty. Multivariate logistic regression also showed that frail participants were more likely to experience limitations in usual activities, after controlling for other covariates. Conclusion: Health care providers who know the determinants of frailty and its relationship with poor functioning will be better prepared to identify at-risk patients with COPD who might benefit from pulmonary rehabilitation.
