Self-Care of Hypertension of Older Adults During COVID-19 Lockdown Period: A Randomized Controlled Trial

COVID-19 pandemic has affected all health aspects and aggravated chronic diseases health disparities because it is more common among vulnerable populations such as seniors 1. Hypertension (HTN) is a long-term chronic disease, affects more than 1 billion people around the world 2. In Jordan, one-third of Jordanian adults are hypertensive 3, one study expected that the prevalence of hypertension in 2013 may increase 7.2% by 2030 4, the HTN deaths rate touched 5% of total deaths, ranks Jordan number 7 in the world, and ranks the HTN at number 6 of leading causes of death, after coronary heart disease and stroke, the first and second leading causes of death in Jordan 5. If high blood pressure is uncontrolled, HTN is the main contributor to heart failure, cardiovascular disease, stroke, kidney disease, and death 2.

Concurrent with COVID-19, care is compromised in the context of lockdown and social distancing. Patients with chronic illness at his time have the risk that they are not obtaining the necessary hospital care, and alternative solutions are required, such as improving patient's self-care of his or her chronic disease 6. Since the hospitals are occupied with COVID-19 cases, the elderly have a perceived threat of COVID-19 and have begun avoiding or delaying health care follow-up 1. It is essential that the investigators find innovative solutions and sustainable methods for patients with HTN to control the blood pressure (BP), enhance self-care, and protect them from COVID-19, and ultimately improve their quality of life.

Engaging the patient in self-care makes him/her an active participant in the management of illness 7. Researchers worked to provide patients with the essential knowledge, skills and abilities to follow treatment recommendations and tolerate blood pressure control 8,9. Although they agreed that the best ways to prevent and manage high BP are through reasonable lifestyle changes, i.e., weight loss, low salt diet, stop smoking, limited alcohol, stress management, exercise, and medication 8, this makes the managing of high BP neither more difficult, nor easier.

However, to support healthy behaviors, the big electronic revolution provides a good opportunity to involve patients suffering from HTN in the health care process and self-care engagement in a safe space 10,11. Moreover, in order to adapt to disruptions during COVID-19, telehealth, mobile health (m-health), and other technologies which support the self-care process and facilitate access to care are appropriate approaches to protect vulnerable populations who are living with chronic diseases 1,12,13. However, improving the self-care of HTN using m-health is not a new approach; it has been studied previously by researchers from different disciplines such as technical medicine, family medicine, and pharmacy 14-19, with less attention given to the nursing role.

In literature, especially nursing literature, there is a lack of sufficient scientific research on the effectiveness of m-Health, guided by nurse's intervention, on self-care of HTN, particularly among older adults12,13. Recently, one study provided a nurse-led program as an example of an effective method to HTN management among older adults 20. The consequences of the COVID-19 pandemic (isolation, social distancing, quarantine) show major challenges in provision of care for older adults with chronic illness 1,6. The m-Health offers a great chance for providing care during the lockdown period, which can be applied via mobile apps 21. Thus, examining m-Health Apps guided by public health nursing (PHN) interventions for the management of HTN in older adults during the pandemic can provide important empirical evidence of effectiveness of such new innovative self-care of HTN interventional methods.
