Effect of Developing and Implementing the HyperCare Nurse-Led Mobile Application on Outcomes of Patients with Hypertension

Background: Hypertension is a major chronic health problem requiring adequate blood pressure control, medication adherence, disease knowledge, and self-management. Mobile health applications may support patients in managing hypertension and maintaining healthy behaviors. Aim: To evaluate the effect of developing and implementing the HyperCare nurse-led mobile application on blood pressure control, medication adherence, and hypertension-related knowledge among patients with hypertension. Methods: A quasi-experimental design was used among 60 adult patients with hypertension at the General Internal Medicine Department, Assiut University Hospital, Egypt. Patients were equally allocated to a study group (n = 30), who used the HyperCare application for three months, and a control group (n = 30), who received routine care. Data were collected using a Patient Assessment Sheet, Hypertension Medication Adherence Sheet, Hypertension Knowledge Questionnaire, and System Usability Scale. Results: The study group had significantly higher total medication adherence scores (6.5 ± 1.6 versus 4.0 ± 2.0) and hypertension knowledge scores (7.73 ± 2.07 versus 4.27 ± 2.52) than the control group (P < 0.001). In the study group, systolic blood pressure decreased from 153.20 ± 12.10 to 126.50 ± 8.40 mmHg, while diastolic blood pressure decreased from 92.40 ± 7.10 to 80.20 ± 5.10 mmHg (P < 0.001). No statistically significant changes were observed in the control group. The System Usability Scale score for patients in the study group was 78.08 ± 13.53 (0–100). Medication adherence was strongly positively correlated with hypertension-related knowledge (r = 0.825, P < 0.001).Conclusion: The HyperCare nurse-led mobile application was associated with significant improvements in blood pressure control, medication adherence, and hypertension-related knowledge among patients with hypertension. Recommendations: Nurse-led mobile applications should be integrated into hypertension management to support blood pressure monitoring, health education, medication adherence, and self-management.
