The effect of health education intervention through mobile phone on hypertension patients : A systematic review.

Introduction: Hypertension is a silent killer disease that, if not handled properly, will lead to dangerous complications for the patient. Health education through mobile phones can be an intervention used to improve health services and the management of hypertension in the community. This study aims to synthesise research findings on the effect of mobile phone health education interventions on hypertensive patients.
Materials and Methods: A systematic review. Search strategy was conducted on international journal databases, namely Scopus, PubMed, ProQuest, Web of Science, and Science Direct with the keywords 'health education', 'mobile phone' and 'hypertension'. Inclusion criteria using PICOS, namely Population: hypertensive patients, Intervention: health education using a mobile phone, Comparation: ordinary health education, Output: knowledge, attitudes, behaviour, Study design: trial method. The publication year 2017-2021.
Results: There were 145 articles found in the search. Articles were identified and screened resulting in five complete articles that met the inclusion criteria. The results of this study found that health education interventions via mobile phones could increase patient knowledge about hypertension; improve self-management; monitor blood pressure; increase adherence to pharmacological treatment, a hypertensive diet, i.e.,low salt intake, vegetable and fruit intake, and physical activity; decrease blood pressure; and improve quality of life. Health education via mobile phones can also provide the latest information quickly to patients about controlling hypertension, antihypertensive drugs, and health services that can be utilised.
Conclusion: Health education interventions via mobile phones have a significant positive effect in controlling hypertension in the community, but it is necessary to consider the patient's age, socioeconomic status, literacy conditions, and ability to use mobile phones to receive the health education that will be provided.
