Abstract
OBJECTIVES: The aim of this study was to evaluate the effects of a home-based pulmonary rehabilitation (PR) programme on anxiety and depressive symptoms, general fatigue and burden in informal caregivers of patients with COPD. We also evaluated the baseline characteristics of both patients and caregivers that contributed to the change in caregiver's outcomes after PR. METHODS: In this retrospective study, patients with COPD were referred to an 8-week home-based PR programme consisting of a weekly supervised 90-min session. Informal caregivers were invited to participate in PR according to the patient's preference and its availability. Caregivers received educational support, behavioural therapies and self-management strategies using the same methods as for patients. Burden, anxiety and depressive symptoms, and general fatigue of caregivers were assessed at baseline and at the end of PR. RESULTS: 241 patients with COPD and 138 (57.3%) caregivers were included. The majority of the caregivers were women (70.5%) and spouses (90.3%) and had at least three comorbidities (57.3%). A large proportion of caregivers showed baseline high burden, anxiety symptoms and abnormal fatigue (40%, 40% and 45%, respectively). Burden, anxiety and depressive symptoms, and general fatigue of informal caregivers were all improved after PR (p<0.05). Long-term oxygen therapy and/or noninvasive ventilation, coronaropathy and/or peripheral arterial disease and a higher baseline modified Medical Research Council Dyspnoea scale score in patients with COPD were associated with a decrease in caregiver's burden after PR. CONCLUSION: A large proportion of caregivers of patients with COPD showed anxiety symptoms, fatigue and a high burden. These outcomes were improved by integrating the caregiver into a home-based PR programme.
