Abstract

OBJECTIVE:

We tested whether remote dielectric sensing (ReDS)-directed fluid management reduces readmissions in patients recently hospitalized for heart failure (HF).

BACKGROUND:

Pulmonary congestion is the most common cause of worsening HF leading to hospitalization. Accurate remote monitoring of lung fluid volume may guide optimal treatment and prevent re-hospitalization. ReDS technology is a quantitative non-invasive method for measuring absolute lung fluid volume.

METHODS:

Patients hospitalized for acute decompensated HF were enrolled during their index admission and followed at home for 90days post-discharge. Daily ReDS readings were obtained using a wearable vest, and were used as a guide to optimizing HF therapy, with a goal of maintaining normal lung fluid content. Comparisons of the number of HF hospitalizations during ReDS-guided HF therapy were made, both to the 90days prior to enrollment and to the 90days following discontinuation of ReDS monitoring.

RESULTS:

Fifty patients were enrolled, discharged, and followed at home for 76.9±26.2days. Patients were 73.8±10.3years old, 40% had LVEF above 40%, and 38% were women. Compared to the pre- and post-ReDS periods, there were 87% and 79% reductions in the rate of HF hospitalizations, respectively, during ReDS-guided HF therapy. The hazard ratio between the ReDS and the pre-ReDS period was 0.07 (95% CI [0.01-0.54] p=0.01), and between the ReDS and the post-ReDS period was 0.11 (95% CI [0.014-0.88] p=0.037).

CONCLUSIONS:

These findings suggest that ReDS-guided management has the potential to reduce HF readmissions in acute decompensated HF patients recently discharged from the hospital.
