Video education for patients with heart failure: A systematic review and meta-analysis

Background: Education is essential for disease management in patients with Heart Failure (HF). Video education, based on adult learning and self-efficacy theories, may enhance outcomes by combining visual and auditory information. No study has comprehensively reviewed the impact of video education on mortality, HF) hospitalization, and Quality of Life (QOL) in patients with HF. Objective: To evaluate the effectiveness of video education in improving the clinical outcomes of patients with HF. Methods: This systematic review followed the 2020 PRISMA guidelines. We included randomized controlled trials that assessed the effectiveness of video education combined with usual care for patients with HF compared with those receiving usual care only. We searched the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, WHO International Clinical Trials Registry Platform, ClinicalTrials.gov, PEDro, and CINAHL until December 2023. We pooled data on mortality, HF hospitalization, and QOL as the primary outcomes. Results: The certainty of evidence was evaluated by the GRADE approach. We included 22 studies with a total of 6614 patients with HF. The evidence is very uncertain about the effect of video education, compared with usual care, on mortality (risk ratio 0.90, 95 % CI 0.70 to 1.15; I2 = 10 %; very low certainty evidence), HF hospitalization (risk ratio 1.10, 95 % CI 0.85 to 1.44; I2 = 14 %; very low certainty evidence), and QOL (standardized mean difference-0.35, 95 % CI-1.07 to 0.37; I2 = 89 %; very low certainty evidence). Conclusion: Currently, video education may not take precedence over established interventions in the management of HF.
