Development of a Mobile Application Called TansiyoRitim for Hypertension Patients

Hypertension, a systemic disease characterized by persistently high blood pressure, is a significant health problem due to its widespread prevalence in the population and the serious complications that can develop if left uncontrolled. In the treatment of hypertension, maintaining blood pressure control is crucial for treatment success. In addition to pharmacological methods, lifestyle modifications such as weight management, smoking cessation, regular exercise, sleep hygiene, salt restriction, balanced nutrition, and stress reduction are also commonly used. The literature reports that interventions aimed at improving the health behaviors of hypertensive patients, presented through methods that encourage active participation and are enriched with digital tools, are more effective than traditional methods in terms of learning outcomes and lasting behavioral change. This study aims to evaluate the effect of a mobile health application structured on King's Goal Achievement Theory on blood pressure control, treatment adherence, and self-efficacy in hypertensive patients. The unique aspect of this research is that the mobile application developed for hypertensive patients offers a learning and care approach that supports mutually goal-oriented interaction between the individual and the system, rather than simply being an information-providing tool. This project, the first of its kind to be conducted under nurse leadership and unique to the culture of the province where the study is taking place, features a mobile application for blood pressure control. Another unique aspect is the development of a collaborative model that contributes to the multidisciplinary management of hypertension through an individualized care protocol structured based on King's Goal Achievement Theory, developed under nurse leadership. These achievements make our project unique and innovative for our country. The research will be conducted in a hospital in Kars using a randomized controlled experimental design including pre-test, post-test, and interim measurements. 160 participants, determined by power analysis, will be randomly assigned to the mobile application group (n=80) and the control group (n=80) via a computer-based randomization list created using the R program. Participants in the mobile app group will begin using the TansiyoRitim mobile app, which is available for download on Google Play and the App Store. The app is structured according to the theoretical components of King's Theory of Targeted Success and is designed to promote behavior change in patients with hypertension. The study outcomes will be evaluated using a Demographic Information Form, a Blood Pressure Monitoring Form, the Hill-Bone Hypertension Treatment Adherence Scale, the Hypertension Self-Efficacy Scale, and a Mobile Application Usability Scale. This project aims to generate scientific evidence regarding the effectiveness of a mobile health application developed for hypertension patients, support individuals' active participation in their health processes through the mobile application, contribute to the dissemination of digital health-based approaches in academic and applied fields, and share the results of this project in international literature.
