Effectiveness of family-based nursing intervention on self-management and blood pressure control among hypertensive patients: A quasi-experimental study

Hypertension remains a major global health problem and is associated with poor self-management behaviors, leading to uncontrolled blood pressure and increased risk of complications. Family involvement has been recognized as an important factor in supporting patient adherence; however, structured family-based nursing interventions are still limited in clinical practice. This study aimed to evaluate the effectiveness of a family-based nursing intervention on self-management and blood pressure control among hypertensive patients. A quasi-experimental study with a pre- and post-test control group design was conducted involving 60 hypertensive patients recruited from a primary health care center. Participants were divided into an intervention group and a control group, each consisting of 30 patients. The intervention group received a structured family-based nursing intervention that included education, active family involvement, home-based blood pressure monitoring, and weekly nurse follow-up. In contrast, the control group received standard care. The intervention group showed a statistically significant improvement in self-management scores after the intervention (mean difference=23.4; 95% confidence interval [CI]: 19.2 to 27.6; P<0.001), indicating a substantial enhancement in patients’ self-management behaviors. A significant reduction in systolic and diastolic blood pressure was observed in the intervention group compared to the control group. In addition, a significant reduction in systolic blood pressure was observed in the intervention group (mean difference=-20.2 mmHg; 95%CI: -25.1 to -15.3; P<0.001), reflecting a clinically meaningful improvement in blood pressure control. This study demonstrates that a structured family-based nursing intervention is effective in improving self-management behaviors and blood pressure control among hypertensive patients. The integration of family support into nursing care offers a practical, scalable approach to enhancing hypertension management in clinical settings.
