Health-Related Quality of Life Among Heart Failure Patients Attending an Outpatient Clinic in the University of Gondar Comprehensive Specialized Hospital Northwest, Ethiopia, 2020: Using Structural Equation Modeling Approach

BACKGROUND: Chronic heart failure is one of the most important public health concerns in the industrialized and developing world having increasing prevalence. Measuring quality of life using rigorous statistical methods may be helpful to provide input for decision-makers and the development of guidelines. This study aimed to assess health-related quality of life and associated factors among heart failure patients attending the University of Gondar Specialized Hospital. METHODS: A cross-sectional study was employed to select 469 heart failure patients who have follow-up at the University of Gondar Specialized Hospital consecutively from March 01 to 30, 2020. Data were entered to Epi Info 7 and exported to STATA version 15 for further statistical analysis. The quality-of-life domains were measured with World Health Organization Quality of Life BREF. Structural equation modeling was employed to estimate the relationships among exogenous, mediating, and endogenous variables simultaneously. RESULTS: Chronic heart failure patients had a significantly lower mean score in physical health domain (31.70 mean score), environmental health domain (38.35 mean score), and in overall quality of life domain (41.61 mean score) moderate in social relation domain (46.22 mean score), and in psychological health domain (50.21 mean score) of health-related quality of life (p-value <0.0001). Age had a direct positive effect on health-related quality of life. Residency also had a direct negative effect on both physical and environmental health-related quality of life domain. Duration of heart failure had a direct negative effect on psychological health. CONCLUSION: The finding of this study indicated that poor health-related quality of life in the physical health domain, moderately poor in overall health-related quality of life, and moderate health-related quality of life in the psychological health domain among Chronic heart failure patients. Age, residence, marital status, income, and duration of HF were significantly associated factors for quality of life among HF patients.
