BackgroundThe influence of physical function of individuals on long-term oxygen therapy (LTOT) on caregiver burden is underexplored. This study investigated the association of caregiver burden with physical function of individuals on LTOT and the association between caregiver's burden and quality of life.MethodsThis was a cross-sectional study. Informal caregivers were assessed for burden using the Caregiver Burden Inventory (CBI), the European Quality of Life 5 Dimension questionnaire index (EQ-5D index) and its Visual Analog Scale (EQ-VAS). Physical function of subjects on LTOT was assessed by dyspnea, activities of daily living (ADLs), and mobility. Univariate and multivariate linear regression models were explored.ResultsFifty-four caregivers (54.7 ± 16.1 y, 74.1% female) were included. CBI total score was correlated with subject's dyspnea (r = 0.369, P = .006) and ADLs (r = 0.300, P = .03). In the multivariate regression models, subject's physical function limitation due to dyspnea explained 26.4% of the CBI total score variance (P = .005). In the CBI dimension analysis, the time-dependence caregiver burden was correlated with subject's dyspnea (r = 0.335, P = .01), ADLs (r = 0.436, P = .001), and mobility (r = -0.415, P = .002). CBI developmental and physical caregiver burden were correlated with dyspnea (r = 0.309, P = .02; r = 0.363, P = .007) and ADLs (r = 0.274, P = .045; r = 0.299, P = .03). Emotional caregiver burden was correlated with dyspnea (r = 0.333, P = .01). Higher CBI total score was correlated with worse quality of life on EQ-5D index (rs= -0.374, P = .005) and EQ-VAS (rs= -0.494, P = .001) in caregivers.ConclusionsIncreased caregiver burden was associated with higher physical limitation due to dyspnea and dependence in ADLs of individuals on LTOT. The increased burden was associated with a worse caregiver's quality of life.Copyright © 2022 by Daedalus Enterprises.
