Introduction Acute decompensated heart failure (ADHF) is a major cause of hospital readmissions despite technological advances and multiple guidelines. Remote dielectric sensing (ReDS) is a non-invasive electromagnetic-based tool that measures absolute lung fluid content. This technology identifies changes in pulmonary pressures before the development of symptoms, hence assists physicians to adjust the medical therapy before clinical worsening. The objective of this meta-analysis is to see the use of Remote Dielectric Sensing (ReDS) in the prevention of heart failure rehospitalizations. Methods Using PubMed, Ovid (MEDLINE), and Cochrane database we searched using the MeSH terms including,” Radar Sensing,” “Remote Dielectric Sensing (ReDS)” Heart failure exacerbations,” Heart failure rehospitalizations,”. The primary outcome was to assess the rate of heart failure rehospitalization with the use of the device. Unadjusted odds ratios were calculated using a random-effect model using RevMan V 5.3. Results Our analysis included a total of 568 patients in the ReDS group and 1167 patients without ReDS. The mean age of the sample was 65.2±12.8 with 66% males and 34% females. We found that patients with ReDS monitoring had lower odds of heart failure rehospitalizations (Odds ratio=0.41; 95% CI=0.31-0.54; p-value Conclusion ReDS monitoring can be beneficial in lowering heart failure rehospitalization by remote monitoring. However, large clinical studies are warranted to further assess its efficacy in reducing hospital readmissions and mortality.
