Knowledge, treatment adherence, and quality of life of heart failure patients at Nhan Dan Gia Dinh Hospital

Abstract

Introduction: Heart failure (HF) is one of the most common diseases worldwide, with a high prevalence and mortality, creating a significant cost burden on patients, society, and the healthcare system. As a result, extensive research has been conducted to investigate advanced treatment methods for heart failure, and patient adherence plays a crucial role in optimizing treatment effectiveness. This study aims to describe the current status of patients’ knowledge, treatment adherence, and quality of life among outpatients with heart failure visiting for routine treatment at Nhan Dan Gia Dinh Hospital. Methods: A descriptive cross-sectional survey was conducted on 330 outpatients with heart failure who were visited for routine treatment at Nhan Dan Gia Dinh Hospital. All data were collected through face-to-face interviews using constructed questionnaires. Results: The study showed the limit of heart failure knowledge among patients, with a mean score of 5.2 ± 2.3. Only 4.8% of patients were adequate overall heart failure knowledge. The treatment adherence was limited, with an overall adherence rate of 20.9%. The patient’s quality of life was generally stable at a high level, with a mean of 0.871 for the descriptive system score and 0.697 for the standardized VAS score. Conclusion: The adherence rate of patients with HF was low, particularly among those with non-drug adherence. Very few patients with heart failure have adequate knowledge of heart failure. More support and health education programs on heart failure treatment adherence are needed for patients to increase their knowledge, adherence and improve their quality of life.
