Investigating the effect of multimedia education in combination with teach-back method on quality of life and cardiac anxiety in patients with heart failure: a randomized clinical trial

BACKGROUND: Education can contribute to promotion of the quality of life and reduction of heart anxiety in patients with heart failure, so it is important to find a suitable educational method for these patients. Therefore, the present study was an attempt to determine the effect of multimedia education using teach-back method on the life quality and cardiac anxiety in patients with heart failure. METHODS: The present study was a randomized clinical trial. 120 patients with heart failure class I to III and aged less than 60 years old were selected using sequential sampling; then, they were assigned randomly into two intervention groups and one control group. Group A (multimedia education), group B (education using multimedia together with teach-back method), and group C (control). The quality of life and cardiac anxiety were evaluated in the participants of the three groups before, after, 1 month, and 3 months after the intervention. Data were analyzed using descriptive tests, Pearson correlation, Kolmogorov–Smirnov, chi square and ANOVA test in SPSS 22. The significance level was set at P < 0.05. RESULTS: No significant differences were found in the mean scores of the quality of life and cardiac anxiety in the control and two intervention groups before the educational intervention. However, immediately after, 1 month and 3 months after the educational intervention, a significant difference was observed between the mean scores of the quality of life and cardiac anxiety in the intervention groups (P < 0.05). CONCLUSION: Multimedia education together with Teach-Back method is effective in promoting the quality of life and reducing cardiac anxiety in patients with heart failure. Therefore, it is recommended that health policymakers should use this educational method in providing treatment programs. IRANIAN REGISTRY OF CLINICAL TRIALS: 20190917044802N1.
