Self-care of hypertension of older adults during COVID-19 lockdown period: a randomized controlled trial

Abstract

Background: COVID-19 pandemic has aggravated chronic diseases and health disparities especially hypertension because it is more common among vulnerable populations such as older adults. Objective: This study aimed to examine the effects of a public health nursing intervention plus m-Health applications for hypertension management on enhancing the self-care, systolic and diastolic of blood pressure, and quality of life in older adults during the lockdown period in Jordan. Methods: A randomized, controlled trial design was performed in Jordan. A total of 120 participants were randomly allocated to three groups (n = 40); interventional group (public health nursing interventions plus m.Health applications) and two control groups (m.Health applications alone group and standard care group). Results: After 3 months, the interventional group show significantly decreased in systolic blood pressure − 14 (F = 16.74, P = 0.001), greater improvement in self-care maintenance, monitoring, and confidence (+ 30, + 17.75, + 40.27; P < 0.01, respectively) compared to the two control groups. Greater improvement in role limitations due to physical health and due to emotional problems, pain, energy/fatigue, emotional well-being, and social functioning of quality of life (P < 0.05) compared to the standard care group. No statistical significant difference was found in diastolic blood pressure (F = 3.91, P = 0.141), physical functioning (P = 0.613), and general quality of life (P = 0.060). Conclusions: This study supports the adoption of technology with nursing intervention as a method of supporting continuity of self-management of chronic illness during the pandemic, and its potential implications for future delivery of health care, not just in Jordan, but across the world.
