New-ts 2: A retrospective analysis of 1262 heart failure patients followed by the newcard telemonitoring system in 2020

Abstract

The NEW-TS 1 study has studied the 3 first years of use of the NEWCARD Telemonitoring system for heart failure. Based of it, different upgrades were implemented in 2020, especially a new algorithm. This study is designed to study a more mature and constant telemonitoring device. To enhance the quality of our protocol, we have also reinforced the monitoring process of hospitalisations. The inclusion criterias of the patients were almost opened to every heart failure one, due to an amendment of the ETAPES experimentation at the start of 2020 with the COVID pandemic. Patients have to be followed as least 3 months during 2020 year. Classical baseline characteristics for heart failure are monitored at the start of the study. Everyday were measured at home 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. Every hospitalization anonymised has to be classified by an independent committee. We will study different parameters (compliance, evolution of datas, alarms generated, types of answers to them, hospitalisations and the predictive value of the system for them). On 1262 patients, the mean age was 75. The averages for baseline medical datas were: 40% for systolic function, 29% for diabetes, 61% for sinusal rhythm. For BNP and NTproBNP, means were 915 and 4018 (pg/ml respectively). We conducted a retrospective study on 1262 patients in order to assess the accuracy of the telemonitoring system NEWCARD in mature and “real life” conditions. We will also take the opportunity of this study to the process. This “real-life” conditions study will be followed by a medico economic study based on the 2020 datas (NEW-TS 3).
