Relationship Between Knowledge and Blood Pressure Among Hypertensive Prolanis Patients at Seto Hasbadi 01 Clinic

Abstract

Hypertension remains a critical global health burden and is frequently termed the “silent killer” because it is often asymptomatic. In Indonesia, the Chronic Disease Management Program (Prolanis) is implemented to support patients in controlling chronic conditions such as hypertension. Theoretically, higher patient knowledge should be associated with better disease management; however, the gap between awareness and clinical outcomes remains a challenge. This study aimed to determine the relationship between knowledge level and blood pressure control among hypertensive patients enrolled in the Prolanis programme at Seto Hasbadi 01 Clinic. A quantitative cross-sectional design was employed. Using purposive sampling, 133 hypertensive Prolanis patients were recruited between February and April 2025. Knowledge of hypertension was measured using a structured questionnaire that had undergone validity and reliability testing, while blood pressure control was determined from clinic records using JNC VIII criteria. Data were analysed with descriptive statistics and Spearman’s Rho correlation. Most respondents had a good level of knowledge (n = 83, 62.4%), yet 70 respondents (52.6%) still had uncontrolled blood pressure. The correlation analysis yielded an r value of 0.017 with a p-value of 0.846 (p > 0.05), indicating no statistically significant relationship between knowledge level and blood pressure control. These findings suggest that knowledge alone is insufficient to ensure blood pressure control and highlight the need to address additional factors such as medication adherence and lifestyle modification to improve clinical outcomes in hypertensive Prolanis patients.
