Abstract:
Introduction: Multimorbidity, the co-occurrence of various chronic conditions, is of major concern in patients with heart failure (HF) because it is associated with impaired quality of life (QOL) and adverse outcomes. Effective self-care is an essential adjunct to evidence-based medical treatment aimed at delaying progression of HF. Hypothesis: This study investigated the relationships between multimorbidity, QOL and level of self-care in HF patients. Methods: Study subjects completed questionnaires on HF-related quality of life (Minnesota Living with Heart Failure questionnaire), HF-related self-care behaviors (European Heart Failure Self-Care Behavior Scale), HF-related knowledge (Japanese heart failure knowledge scale) and depression symptoms. Comorbidities and other clinical and social characteristics were also assessed. Analyses of covariance and multivariate linear regression were used to assess associations between multimorbidity and QOL. Results: A total of 231 outpatients with HF were assessed; 119 with poor self-care (self-care score 〈 34) and 112 with adequate self-care (self-care score≥34); mean age 65.8 ± 13.9 and 69.8 ± 13.7 years, respectively. Of these patients, 57.6% had three or more additional chronic conditions; the most prevalent being hypertension (56.0%) and chronic kidney disease (46.6%). Patients with multimorbidity had worse QOL than patients without (P 〈 0.01). Subjects with poor self-care and multimorbidity had worse QOL than those without multimorbidity (P 〈 0.01); however, there was no association between multimorbidity and QOL in patients with adequate self-care. Multivariate analysis controlling for the effects of other variables showed that multimorbidity was an independent determinant of QOL overall and in poor self-care patients (sβ = 0.15, P = 0.04; sβ = 0.28, P 〈 0.01, respectively). However, in patients with adequate self-care, multimorbidity was not associated with QOL. Conclusions: Multimorbidity is an independent determinant of QOL in HF patients with poor self-care. To improve their QOL, both reinforcement of adequate self-care behavior regarding their HF and a multidimensional approach to enhancing self-management of their comorbidities are needed.
