Background
Patients recently hospitalised for heart failure (HF) face a high risk of readmission and mortality. Remote monitoring programs (RMPs) may offer a scalable, non-invasive strategy to improve outcomes in this vulnerable population.
Methods
This prespecified sub-analysis of the real-world TELESAT-HF study included patients with heart failure who had experienced at least one HF-related hospitalization in the year preceding study entry. Patients enrolled in the Satelia®Cardio RMP were identified and subsequently matched to controls receiving SoC from the French national health database. The primary endpoint was all-cause mortality, while secondary endpoints included HF-related rehospitalizations and cumulative days spent in hospital. Healthcare costs were also explored.
Results
A total of 1,258 patients managed with RMP (mean age 73 years, 33% women) were matched to 2,321 SoC controls. Compared with SoC, patients in the RMP group exhibited a lower risk of all-cause mortality (23.5% vs. 39.6%; HR 0.54, [95%CI 0.47; 0.63]; p<0.0001), a lower rate of HF-related hospitalizations (rate ratio 0.85, [95%CI 0.78; 0.94]; p=0.0015), and fewer cumulative days spent in hospital (estimated absolute difference −1.67, [95%CI −2.78; −0.56]%; p=0.003) (Figure 1). No statistically significant differences in healthcare costs were observed between groups (Figure 2). Subgroup analyses suggested broadly consistent associations across age, sex, RMP modality, and the number of prior HF hospitalizations (Figure 1).
Conclusion
Among patients recently hospitalized for HF, participation in a non-invasive RMP was associated with substantially lower mortality, fewer HF rehospitalizations, and reduced time spent in hospital. These findings support the potential role of RMP as part of routine post-discharge HF care.Overall and subgroup analysis - prim outFor image description, please refer to the figure legend and surrounding text.Total (A) costs and (B) componentFor image description, please refer to the figure legend and surrounding text.
