Substudy of MEET-OS (NCT04948632): Monitoring of Patients After Ambulatory Surgery by Biobeat® Devices

Ancillary Study: Monitoring of Patients After Ambulatory Surgery by Biobeat® Devices: Pilot Feasibility Study

The objective of this ancillary study of the MEET-OS study is to assess the technical feasibility of using Biobeat® monitoring devices after ambulatory surgery at high risk of complications.

The secondary objectives are to assess: i) the patient's experience and tolerance ii) the occurrence of clinical disturbances in the patients's home after ambulatory surgery with high risk of postoperative complications iii) to determine the impact of the data obtained with the monitoring devices on the clinical care decisions during postoperative follow-up.

With increasingly complex surgeries and increasingly comorbid patients, ambulatory surgery are not always at low risk of postoperative complications. Among the new support tools available for monitoring patients remotely, devices for monitoring vital signs could be of interest to healthcare staff in charge of monitoring, more precisely when comorbid patients are involved or when interventions at high risk of complications are performed.

Inclusion Criteria:

• Patients over 18 years old undergoing elective outpatient surgery under general or regional anesthesia
• Internet access for the patient or their caregiver from home
• Written, oral and spoken comprehension of French
• Considered to be at high risk of postoperative complications, defined by one of the following two criteria: an ASA 3 score or an ASA score of 2 + surgery at intermediate or high risk according to the classification of Glance and al.

Exclusion Criteria:

• Patient's or caregiver's inability to learn and to use digital technologies
• Conversion of ambulatory to inpatient hospitalization on the day of surgery
• Patient's refusal
• Operation performed under regional or neuraxial anesthesia alone
• Trophic skin disorders contraindicating the installation of the Biobeat® monitoring device on the torso (deformation, irritation, infection, ulceration, etc.)
• Patient with pacemaker
• MRI or CT scheduled post-operatively
• Tattoo on the torso or refusal to shave the area where the Biobeat® monitoring device should be installed
• Pregnant or breastfeeding women
• Allergy to one of the technological components
