Remote management of worsening heart failure events and subsequent rate of emergency department admission

Abstract Background Worsening heart failure (WHF) is the leading cause of hospitalization among individuals aged ≥ 65 years and constitutes a substantial burden for both the patient and the healthcare systems. Moreover, heart failure contributes to exacerbate the pressure on emergency departments which are involved in 64% of heart failure hospital admission (1). Remote management of heart failure as been shown to reduce the number of days lost due to unplanned cardiovascular hospitalizations and all-cause mortality (2, 3), but little is known about the effect on the emergency healthcare use. We aimed to describe the effect of a telemonitoring program on the rate of emergency admissions for WHF in chronic heart failure patients. Methods All patients enrolled in the heart failure remote management program of two French centers between 13 April 2020 and 31 January 2023 were included in the study. Follow-up data were collected until 31 January 2023. Inclusion criteria were chronic heart failure (HF) with New York Heart Association ≥II and an elevated B-type natriuretic peptide (BNP > 100 pg/mL or N-terminal-pro-BNP > 1000 pg/mL). Remote evaluation included measurements of body weight, blood pressure, heart rate, symptoms, biochemical parameters, and data from cardiac implantable electronic devices when available. Results A total of 1,095 patients (72±11.8 years old, 69.7% male), were followed for a median [IQR] of 437 [182; 739] days with a mean adherence to the remote monitoring system of 67.6±30.3%. Over this period, 198 (18.1%) patients had 949 WHF events, the majority of whom were remotely detected: 830 (87.5%). Overall, 246 (26%) of the WHF episodes required hospitalisation and 109 (11%) prompted an emergency department visit. When the WHF event was remotely detected, hospitalization was only required in 127 (15%) cases and the rate of emergency department visit was reduced to 3%. Conclusion In HF patients engaged in a multiparametric remote management program, the rate of emergency department admission is very low. Adopting such a strategy for patients with chronic HF may be useful in reducing emergency department overcrowding.Baseline characteristics of patientsPatients course and use of resources
