Telemonitoring of heart failure in entering step by step into the daily practice especially in France with the ETAPES experimentation

NEWCARD is one of the solutions involved in this experimentation. The aim of this retrospective study is to describe the characteristics of the patients followed by NEWCARD, their evolution and how the system was able to improve their medical history.

The inclusion criterias of the patients are based on the ETAPES experimentation (especially hospitalisation for heart failure within 12 months). Patients have to be followed as least 2 months and then as long as they want to do so. Classical baseline characteristics for heart failure are monitored at the start of the study. Everyday were measured at home for every patient weight, heart rate, blood pressure and dyspnea status. Those datas were analysed by the system algorithm and alarms were sent and monitored according to the NEWCARD process. Events (especially death and hospitalisations) were monitored by 3 differents sources: NEWCARD nurses, patients and their cardiologists. We will calculate the predictive values, sensibility and specificity of the ongoing algorithm used routinely. We will then do the same retrospectively with the actual algorithm. Ultimately, we will use artificial intelligence to improve it.

We will present the results of 465 patients followed from 2 to more than 30 months. 30% of them have an ejection fraction of more than 50%; almost 45% are 80 years old or more. 300,000 datas have been collected.

The aim of this retrospective study is triple 1/to evaluate the NEWCARD telemonitoring system after 3 years of implementation 2/to use this experience to improve especially the algorithm 3/all those results will help to design a prospective study which will start at the end of 2020.
