A Study of the Quality of Life and Related Factors in Re-Hospitalized Patients with Heart Failure
Main Article Content
Abstract
Abstract
Background: The factors influencing rehospitalization of heart failure patients include dietary noncompliance, medication nonadherence, lack of social support, and poor self-care behaviors, which in turn affect patient treatment adherence, socioeconomic status, quality of healthcare, and quality of life. Therefore, the purpose of this study explored the quality of life of rehospitalized heart failure patients and associated factors.
Objectives: The main purpose of this study was to explore the quality of life and associated factors of rehospitalized heart failure patients.
Methods: This study employed a cross-sectional survey design and used convenient sampling for the participant recruitment from April to June of the 113th year of the Republic of China. The study participants were rehospitalized heart failure patients from a medical center in northern Taiwan. A total of 33 participants were enrolled. Data was collected using questionnaires including basic properties, quality of life scale, social support scale, medication adherence scale and the European Heart Failure Self-Care Behavior Scale. Data analysis was conducted using the SPSS 24.0 statistical software. The statistical methods used included t-tests, Pearson’s correlation analysis, and multiple linear regression and hierarchical regression analyses to assess the predictors of quality of life and their explanatory power.
Results: The results of the study indicated that the quality of life of rehospitalized heart failure patients significantly correlated with the following factors: primary caregiver (t = -2.40, p < .05), self-care ability (t = -2.52, p < .01), chronic kidney failure (including Stage III-V) (t = 2.23, p < .05) and abnormal potassium levels in hemodynamics (t = 2.17, p < .05). The quality of life showed a low, non-significant positive correlation with social support, and a low, non-significant negative correlation with medication adherence and self-care behaviors. Predictive factors for the quality of life included living situation, self-care ability, hypertension, chronic kidney failure (including Stage III-V), duration of heart failure, days since the last hospitalization, social support, and quality of life. These factors accounted for 64% of the explanatory power, and after adjustment, 54% remained (F = 6.42, p < .05). Among all the factors, days since the last hospitalization had the highest explanatory power for quality of life.
Conclusion: While causality cannot be inferred due to the study’s cross-sectional design, the findings suggest that improving self-care capacity and supporting patients post-discharge may enhance QoL and potentially reduce the likelihood of readmission. It is recommended that future studies increase the sample size and conduct larger cross-sectional or longitudinal studies to verify these associations.
