Abstract
BACKGROUND: Health education is important for self-care in patients with heart failure. However, the evidence for the effect of distance education as an intervention to deliver instruction for patients after discharge through digital devices on self-care is limited. OBJECTIVES: In this study, our aim was to explore the effect of distance education on self-care in patients with heart failure. METHODS: We searched 11 electronic databases and 3 trial registries for randomized controlled trials with low risk of bias and high-quality evidence to compare the effect of usual and distance education on self-care. Quality appraisal was performed using the Cochrane Risk of Bias Tool. Using the Review Manager 5.4 tool, a meta-analysis was conducted. Certainty of the evidence was rated using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE). RESULTS: Fifteen articles were eligible for this study. Compared with usual education, distance education improved self-care maintenance (mean difference [MD], 6.62; 95% confidence interval [CI], 3.93-9.31; GRADE, moderate quality), self-care management (MD, 5.10; 95% CI, 3.25-6.95; GRADE, high quality), self-care confidence (MD, 6.66; 95% CI, 4.82-8.49; GRADE, high quality), heart failure knowledge (MD, 0.78; 95% CI, 0.01-1.56; GRADE, moderate quality), and quality of life (MD, -5.35; 95% CI, -8.73 to -1.97; GRADE, moderate quality). Subgroup analysis revealed distance education was more effective than usual education in self-care when the intervention was conducted for 1 to 6 months, more than 3 times per month, and a single intervention lasting more than 30 minutes. CONCLUSIONS: This review shows the benefits of distance education on self-care, heart failure knowledge, and quality of life of patients with heart failure. The intervention duration, frequency, and duration of a single intervention could have affected the intervention effect.
