Perioperative Smart Device Monitoring to Predict Complications

This is a prospective, single-center, observational study designed to to quantify complications following non cardiac intermediate and high-risk surgery, and to identify digital biomarkers (collected pre, and post-operatively by a connected device) enabling early early identification of patients with post-operative complications. Patients will be invited to wear a smartdevice during the perioperative period, and will receive questionnaires about their their health status.
