Effectiveness of a Nurse-Led Support Programme Using a Mobile Application versus Phone Advice on Patients at Risk of Coronary Heart Disease - A Pilot Randomized Controlled Trial.

Purpose: Coronary heart disease (CHD) is the leading cause of morbidity and mortality globally. This study aimed to examine the preliminary effect of a nurse-led support programme using a mobile application versus nursing telephone advice on patients at risk of CHD living in the community. Patients and Methods: A prospective randomized controlled trial was adopted. Sixty eligible CHD participants were randomized into the app group (App) or the nursing telephone advice (NTA) group to support their own health care and exercise. Data were collected at baseline (T0), 1 month (T1), and 3 months (T2). Outcomes were total amount of exercise, self-efficacy of chronic disease management, total time of exercise, blood pressure, and lipid concentrations. Data were analyzed using the generalized estimating equation models. Results: Ninety-two individuals were screened for eligibility and 60 were randomized into the app group (n = 30) or NTA group (n = 30). The mean age of the participants was 60.92. The total attrition rate at T2 was 1.66%. The app group showed a moderate effect (Cohen's d =0.43) in significant increase in exercise amount, and reduction of lipid concentration (total cholesterol d=-0.43, triglyceride d=-0.39) respectively. Other outcomes showed improvement trend but non-significant between group. Conclusion: The CHD app is effective to motivate CHD patients for maintaining exercise amount which will be beneficial to their lipid control.
