Validation of a Connected Patch, an Alternative to Conventional Monitoring

The hypothesis is that this connected patch could be used in surgical departments to detect early a cardiovascular or respiratory complication and therefore to treat it without delay. However, it has not been validated in a hospital setting; that is the purpose of this project. This step of validating the connected monitoring object is required in different places: post-interventional surveillance room that approaches a conventional hospital room, and operating room where artifacts are numerous. Validation will be done by comparing data from General Electric's conventional monitors, with data from patches.

Study Overview

• Status: Withdrawn
• Conditions: Anesthesia
• Intervention / Treatment: Device: Patch validation

Detailed Description

When patients operated on outside intensive care or intensive care units are hospitalized, vital signs are collected intermittently by various conventional devices. During the follow-up period of these patients, it is possible that abnormal vital signs that may identify clinical deterioration may appear a few minutes to a few hours before a serious adverse event (infection etc.) occurs. These signals often go unnoticed due to infrequent monitoring.

The establishment of teams to ensure a rapid response would improve the safety of hospitalized patients for whom the detection of abnormal vital signs predictive of clinical deterioration would generate an alarm. This system is based on the identification of patients at risk and the rapid intervention of the team.

One of the crucial issues is therefore the speed of the alarm and its reliability.

The evolution of electronic technology offers the possibility of using inexpensive portable devices (connected patches) that can provide information on vital signs in real time. Vital signs collected by these devices could be analyzed to predict clinical deterioration prior to hospital staff visits, especially at night and on weekends when staffing levels are generally lower.

The connected patch used in this research is the Scaléo Médical company's device "myAngel VitalSigns". The long-term objective would be to be able to use this connected patch in surgical departments to detect early a complication, particularly of a cardiovascular or respiratory nature, and therefore to treat it without wasting time. However, it has not been validated in a hospital setting; that is the purpose of the project.

The objective of this research is therefore to validate Scaléo Médical's connected patch in different locations: post-interventional surveillance room that approaches a conventional hospital room, operating room where artifacts are numerous.

Concordance of temperature value measured by 2 different devices after surgery	Comparison between temperature measured by conventional medical monitoring device and by connected patch	36 hours maximum after the surgery

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Concordance of blood pressure value measured by 2 different devices during surgery	Comparison between blood pressure measured by conventional medical monitoring device and by connected patch	During surgery
Concordance of heart rate value measured by 2 different devices during surgery	Comparison between heart rate measured by conventional medical monitoring device and by connected patch	During surgery
Concordance of respiratory rate value measured by 2 different devices during surgery	Comparison between respiratory rate measured by conventional medical monitoring device and by connected patch	During surgery
Concordance of arterial oxygen saturation value measured by 2 different devices during surgery	Comparison between arterial oxygen saturation measured by conventional medical monitoring device and by connected patch	During surgery
Concordance of temperature value measured by 2 different devices during surgery	Comparison between temperature value measured by conventional medical monitoring device and by connected patch	During surgery
Blood pressure artifact	Value of blood pressure will be considered as artifact if systolic blood pressure value < 80 or > 200 and diastolic blood pressure > 110	From surgery to 36 hours maximum after the surgery
Heart rate artifact	Value of heart rate will be considered as artifact if value < 40 or > 140	From surgery to 36 hours maximum after the surgery
Respiratory rate artifact	Value of respiratory rate will be considered as artifact if value < 8 or > 36	From surgery to 36 hours maximum after the surgery
Arterial oxygen saturation artifact	Value of arterial oxygen saturation will be considered as artifact if value < 85 %	From surgery to 36 hours maximum after the surgery
Acceptability of connected patch: numerical scale	Evaluation of connected patch with a simple numerical scale between 0 and 10: 0 representing a very poor tolerance of the device and leading to premature interruption of the collection and 10 a perfect tolerance allowing the patch to be maintained for several consecutive days	During the surgery and through study completion
