Non-invasive telemonitoring programs for patients with chronic heart failure: A systematic review and meta-analysis of randomized controlled trials

Abstract

AimsTo assess whether telemonitoring improves outcomes in patients with chronic heart failure.Methods and resultsA literature search was conducted on studies of randomized controlled trials involving non-invasive telemonitoring and heart failure using Medline, Embase, and Cochrane Library. The primary outcomes were all-cause mortality, all-cause hospitalization, and hospitalization for heart failure. Secondary outcomes were length of stay, health-related quality of life as assessed by validated questionnaires, healthcare costs and cost-effectiveness, and self-care behaviors. We performed a meta-analysis using a random effects model for the primary outcomes. The effect measure was odds ratio with corresponding 95% confidence interval, and heterogeneity among studies was assessed using the Higgins I² value. We screened 212 references, and 34 randomized controlled trials were included in this review. A total of 16179 participants with heart failure were included. Non-invasive telemonitoring reduced all-cause mortality by 18% (OR 0.82, 95% CI 0.71 to 0.95; participants = 15,211; studies = 28; I² = 34%; GRADE: moderate-quality evidence) and heart failure hospitalization by 20% (OR 0.80, 95% CI 0.69 to 0.94; participants = 7491; studies = 18; I² = 31%; GRADE: moderate-quality evidence). Non-invasive telemonitoring didn't demonstrate significant benefit on all-cause hospitalization (OR 0.93, 95% CI 0.82 to 1.05; participants = 11,565; studies = 25; I² = 49%).ConclusionTelemonitoring programs in patients with heart failure were associated with a reduction in all-cause mortality and heart failure hospitalization without harmful events.
