ASSESSMENT OF HEART FAILURE KNOWLEDGE IN OUTPATIENTS WITH CHRONIC HEART FAILURE AT THONG NHAT HOSPITAL

Abstract

Chronic heart failure is one of the leading causes of hospitalizations, impaired quality of life, and increased socioeconomic burden. Adequate disease awareness and effective self-care are key factors in improving prognosis and reducing hospital readmissions. A crosssectional descriptive study was conducted from January 1 to May 31, 2025, involving 200 patients. The tools used included the Dutch Heart Failure Knowledge Scale (DHFKS), a qualityof-life questionnaire, and a self-care assessment. Results: 66% of patients were aged ≥60 years, 94.5% had health insurance, and 78.5% resided in urban areas. Heart failure with reduced ejection fraction (HFrEF) accounted for 73.5%, significantly higher among patients aged ≥60 years (78.8%, p = 0.026). Hypertension (91%) and dyslipidemia (77%) were the most common comorbidities. A total of 78% of patients demonstrated good knowledge of heart failure. Regarding self-care behaviors, most adhered to a low-salt diet and regular weight monitoring, though physical activity remained suboptimal. Dyspnea and lower limb edema significantly impacted quality of life. When symptoms occurred, patients commonly contacted healthcare providers. Conclusions: The majority of outpatients with chronic heart failure demonstrated good disease awareness; however, improvements in self-care practices and multidimensional support are needed to enhance quality of life and reduce disease burden.
