Abstract

Background: Hypertension is a common chronic disease with many potentially serious complications, requiring effective management. Evaluating patients’ knowledge about the disease helps determine their level of awareness, thereby enabling appropriate interventions to improve blood pressure control. Objective: To evaluate knowledge about hypertension and some identify related factors in outpatients at Can Tho Cardiovascular Hospital in 2024-2025. Materials and methods: A descriptive cross-sectional study was conducted on 151 outpatients with hypertension via using convenience sampling method. Direct interviews on disease knowledge were performed using the Hypertension Knowledge-Level Scale (HK-LS) with 22 questions. Results: Patients had an average age of 63.70±9.71 years; primarily female (60.3%) and aged over 60 years (66.9%). The majority suffered from multiple comorbidities, used ≥ 5 medications (84.8%), had the disease for ≥ 5 years (76.2%), and 59.6% of patients could not differentiate antihypertensive medications from others. The proportion of patients with good knowledge of hypertension was 55.6%, the mean knowledge score was 17.47 ± 3.00. Multivariable logistic regression showed that educational levels of high school (OR=7.592; p=0.029), intermediate/college/university or higher (OR=37.312; p=0.014) as well as the ability to differentiate between antihypertensive medications (OR=2.341; p=0.04) were statistically significantly associated with good knowledge about hypertension. Conclusion: Patients' knowledge about hypertension is still limited. Educational level and the ability to differentiate between antihypertensive medications were identified as factors associated with hypertension knowledge.
