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.
Interventions
DEVICEMultiSense® remote monitoring
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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. | From patch placement to hospital discharge, assessed up to 3 hours | Accuracy is defined as an average measurement variation less than 5 bpm of the mean value, with respect to the reference standard |
| Determination of the safety and performance of the MultiSense® solution in patient monitoring, in terms of data availability. | From patch placement to removal, assessed up to 7 days | Percentage of missing data due to technical issues (non-behavioral events) over the monitoring period below 15%. |
| Determination of the safety and performance of the MultiSense® solution in patient monitoring, in terms of data artefacts. | From patch placement to removal, assessed up to 7 days | 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. |
| Determination of the safety and performance of the MultiSense® solution in patient monitoring, in terms of data transmission. | From patch placement to removal, assessed up to 7 days | Data transmission is defined as more than 90% of data with transmission time from patch to server less than 5 min. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Patient's satisfaction and reassurance when monitored by the device | From patch placement to its removal (up to 7 days) | Determination of patient satisfaction and reassurance by an end-study questionnaire (4-levels Likert scale) |
| Patch autonomy | From patch placement to its removal (up to 7 days) | Percentage of patches with an autonomy \> 5 days including skin adhesion and battery life (MultiSense® data and patient's questionnaire) |
| Respiratory rate accuracy in terms of impedance | From patch placement to hospital discharge, assessed up to 3 hours | Respiratory rate accuracy by comparison of MultiSense® data with the reference monitor in terms of impedance |
| Respiratory rate accuracy in terms of EtCO2 | From patch placement to hospital discharge, assessed up to 3 hours | Respiratory rate accuracy by comparison of MultiSense® data with the reference monitor in terms of EtCO2 |
| Patient's tolerance to prolonged use of the MultiSense® solution (Safety in use, side effects) | From patch placement to its removal (up to 7 days) | Accounting and classification of unexpected local and distant event due to the use of the MultiSense® solution (vigilance data) and Patient's questionnaire |
| MultiSense® data quality after moderate level of activity | From patch placement to its removal (up to 7 days) | Distribution of activity level across monitoring period, number of showers taken over the monitoring period and evolution of the artefact's metric (as defined in the primary endpoint) over time (MultiSense® data) |
| Correlation between body temperature and skin temperature | From patch placement to hospital discharge, assessed up to 2 days | Correlation between the body temperature measured with a standard device and the skin temperature measured with the MultiSense® solution |
| End of study hardware recovery rate | From patch removal to material return, assessed up to 1 month | Percentage of MultiSense® patch and gateway returned to RDS at the end of the study |
| Estimation of posture and activity level reported by the MultiSense® solution | From patch placement to its removal (up to 7 days) | Determination of the posture and activity level consistency by accounting the percentage of lying position and low activity at night and the percentage of high activity during day (MultiSense® data) |
| Device defects | From patch placement to its removal (up to 7 days) | Accounting of device deficiencies reported by the investigator, the patient or identified by MultiSense data analysis |
| Clinical relevance of the notifications provided by MultiSense® solution | From patch placement to its removal (up to 7 days) | 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) |
| Remote monitoring facilitation for the healthcare professional through the solution's ease of use and satisfaction gained | From patch placement to its removal (up to 7 days) | Determination of healthcare professionals' practical interest in the solution and satisfaction of use assessed via a questionnaire (4-levels Likert scale) |
