After 3 months, the intervention group using a smartphone-based app had statistically significantly better quality of life scores and dimension scores than the control group (P<.001). The reported effect size for quality of life was 1.85 (95% CI 1.41-2.3).

Abstract

BACKGROUND: Patients with heart failure have low quality of life because of physical impairments and advanced clinical symptoms. One of the main goals of caring for patients with heart failure is to improve their quality of life. OBJECTIVE: The aim of this study was to investigate the effect of the use of a smartphone-based app on the quality of life of patients with heart failure. METHODS: This randomized controlled clinical trial with a control group was conducted from June to October 2018 in an urban hospital. In this study, 120 patients with heart failure hospitalized in cardiac care units were randomly allocated to control and intervention groups. Besides routine care, patients in the intervention group received a smartphone-based app and used it every day for 3 months. Both the groups completed the Minnesota Living with Heart Failure Questionnaire before entering the study and at 3 months after entering the study. Data were analyzed using the SPSS software V.16. RESULTS: The groups showed statistically significant differences in the mean scores of quality of life and its dimensions after the intervention, thereby indicating a better quality of life in the intervention group (P<.001). The effect size of the intervention on the quality of life was 1.85 (95% CI 1.41-2.3). Moreover, the groups showed statistically significant differences in the changes in the quality of life scores and its dimensions (P<.001). CONCLUSIONS: Use of a smartphone-based app can improve the quality of life in patients with heart failure. The results of our study recommend that digital apps be used for improving the management of patients with heart failure.
