Long-term impact of home-based monitoring after an admission for acute decompensated heart failure: a systematic review and meta-analysis of randomised controlled trials

Background: Patients with heart failure have high rehospitalisation rates and poor cardiovascular outcomes. Home-based monitoring (HBM) has emerged with promising results in different settings. However, its long-term effects on patients recently admitted for acute decompensated heart failure (ADHF) remain uncertain. Methods: statistics and sensitivity analysis. The protocol for this systematic review and meta-analysis was registered in the International Prospective Register of Systematic Reviews (PROSPERO, CRD42023465359). Findings: We included 16 RCTs comprising 4629 patients, of whom 2393 (51.7%) were randomised to HBM and 3150 (68%) were men. Follow-up ranged from six to fifteen months. As compared with UC, HBM significantly reduced all-cause mortality (RR 0.75; 95% CI 0.61, 0.91; p = 0.005), all-cause hospitalisations (RR 0.82; 95% CI 0.70, 0.97; p = 0.018), cardiovascular (CV) mortality (RR 0.53; 95% CI 0.36, 0.79; p = 0.002), hospitalisations for heart failure (RR 0.75; 95% CI 0.62, 0.91; p = 0.004), and CV hospitalisations (RR 0.72; 95% CI 0.55, 0.95; p = 0.018). There were no significant differences in length of hospital stay (MD 0.97 days; 95% CI -0.90, 2.84; p = 0.308). Interpretation: In patients recently admitted with ADHF, HBM significantly reduces long-term all-cause mortality and hospitalisations, CV mortality and hospitalisations, and hospitalisations for heart failure, as compared with UC. This supports the implementation of HBM as a standard practice to optimise patient outcomes following admissions for ADHF. However, future studies are warranted to evaluate the efficacy and safety of implementing HBM in the real-world setting.
