The SENSE-ECO study is a prospective, randomized trial of 490 high-risk patients designed to show that the MultiSense® remote monitoring patch safely reduces hospital stays following major digestive surgery. By continuously tracking vital signs for five days at home, the device aims to maintain clinical safety and quality of life while decreasing overall healthcare costs for the French medical system.

SENSE-ECO study is a prospective, multicenter, randomized open-label trial designed to evaluate the clinical and medico-economic impact of the MultiSense® remote monitoring solution for 490 high-risk patients (ASA 2 or 3) undergoing major digestive surgery. The primary objective is to demonstrate that using this Class IIa wearable patch to monitor vital signs-such as heart rate, $SpO_2$, and respiratory rate-allows for a reduced initial hospital stay without increasing 30-day morbidity compared to standard care. In the experimental group, patients are equipped with the device 12 to 24 hours before discharge to continue continuous home monitoring for five days, while the study also assesses secondary factors including cost-effectiveness for the French healthcare system, patient quality of life via the fQoR-15 questionnaire, and organizational workload for medical staff. Conducted across five centers under the coordination of Dr. Ugo Marchese.
