Safety and Performance Study of the MultiSense® Ambulatory Telemonitoring System for Non-critical Patient Management

Study Overview
=================
Brief Summary
-----------------
In this clinical investigation, the investigators will assess the safety, performances and clinical added value of the MultiSense® ambulatory telemonitoring solution in real-life situations.

Detailed Description
-----------------
The MultiSense® solution is a medical device for telemonitoring for in and outpatient use. It includes 5 physiological data sensors and communicates via Bluetooth with a smartphone. The data is centralized in the web and a web application allows healthcare professionals to scrutinize patient's data. Among its potential benefits, the MultiSense® solution offers continuous, non-invasive and wireless physiological data recording over 5 days whenever patient monitoring is needed. There is a special focus on the post-operative monitoring, especially during the initial convalescence phase outside the hospital. An automatic notification system can be set up by a healthcare professional to notify abnormal data and potential need for phone call and/or physical home intervention. The aim of this study is to evaluate the safety, the performance and added value of the MultiSense® solution in real-life situations. The study population includes 20 post-surgical patients having a genuine need for post-hospital monitoring and be likely to have variations in physiological variables monitored, without being in a critical condition. The patients included will be equipped with the MultiSense® solution prior to the hospital discharge. The device will be used for 6 days from the date of actual deployment.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: MultiSense® remote monitoring<br>The patients included will be equipped with the MultiSense® solution prior to the hospital discharge. The device will be used for 6 days from the date of actual deployment. | Device: MultiSense® remote monitoring<br>* At hospital, the patient will be monitored with conventional monitoring devices as well as the MultiSense® solution (at least one hour with a reference monitor). After hospital discharge, the patients will be remotely monitored by their healthcare professional using the MultiSense® solution.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Determination of the safety and performance of the MultiSense® solution in patient monitoring, in terms of heart rate accuracy by comparison with a reference monitor. | Accuracy is defined as an average measurement variation less than 5 bpm of the mean value, with respect to the reference standard | From patch placement to hospital discharge, assessed up to 3 hours | 
| Determination of the safety and performance of the MultiSense® solution in patient monitoring, in terms of data availability. | Percentage of missing data due to technical issues (non-behavioral events) over the monitoring period below 15%. | From patch placement to removal, assessed up to 7 days | 
| Determination of the safety and performance of the MultiSense® solution in patient monitoring, in terms of data artefacts. | Percentage of artefacts due to technical issues (non-behavioral events) over the monitoring period below 10% for heart rate, 20% for the respiratory rate or 30% for SpO2. | From patch placement to removal, assessed up to 7 days | 
| Determination of the safety and performance of the MultiSense® solution in patient monitoring, in terms of data transmission. | Data transmission is defined as more than 90% of data with transmission time from patch to server less than 5 min. | From patch placement to removal, assessed up to 7 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Patient's tolerance to prolonged use of the MultiSense® solution (Safety in use, side effects) | Accounting and classification of unexpected local and distant event due to the use of the MultiSense® solution (vigilance data) and Patient's questionnaire | From patch placement to its removal (up to 7 days) | 
| Device defects | Accounting of device deficiencies reported by the investigator, the patient or identified by MultiSense data analysis | From patch placement to its removal (up to 7 days) | 
| Clinical relevance of the notifications provided by MultiSense® solution | Relevance of the notifications generated by MultiSense® will be judged on the relevance of the notification's functionality by the healthcare professional in real-life situation by the mean of a questionnaire (4-levels Likert scale) | From patch placement to its removal (up to 7 days) | 
| Clinical relevance of the notifications provided by MultiSense® solution | Relevance of the notifications generated by MultiSense® will be judged on the relevance of the notification's functionality by the healthcare professional in real-life situation by the mean of notification treatment through MultiSense® web application | From patch placement to its removal (up to 7 days) | 
| Remote monitoring facilitation for the healthcare professional through the solution's ease of use and satisfaction gained | Determination of healthcare professionals' practical interest in the solution and satisfaction of use assessed via a questionnaire (4-levels Likert scale) | From patch placement to its removal (up to 7 days) | 
| Patient's satisfaction and reassurance when monitored by the device | Determination of patient satisfaction and reassurance by an end-study questionnaire (4-levels Likert scale) | From patch placement to its removal (up to 7 days) | 
| Patch autonomy | Percentage of patches with an autonomy > 5 days including skin adhesion and battery life (MultiSense® data and patient's questionnaire) | From patch placement to its removal (up to 7 days) | 
| Respiratory rate accuracy in terms of impedance | Respiratory rate accuracy by comparison of MultiSense® data with the reference monitor in terms of impedance | From patch placement to hospital discharge, assessed up to 3 hours |
