The goal of this clinical trial is to demonstrate the superiority of remote monitoring with the Bora Care solution in patients with COPD and frequent exacerbations (experimental group) compared to conventional follow-up alone (control group) on the total number of hospital days per patient for respiratory deterioration over 12 months of follow-up.

The main question it aims to answer is: Does remote monitoring of COPD patients reduce the average annual length of hospitalization for exacerbations of COPD patients?

All participants will benefit a conventional clinical follow-up.

Participants in experimental group will also benefit from the Bora care remote monitoring system.

Control group (control): conventional follow-up For the target population (frequent exacerbating COPD patients), the usual follow-up includes two consultations with the general practitioner and one consultation with the pulmonologist per year. The inclusion and follow-up visit at 12 months by a pulmonologist are consistent with the follow-up of COPD patients in current practice and the recommendations of HAS (National Authority for Health) and SPLF (French-Language Society of Pneumology).

Experimental group (conventional monitoring + remote monitoring):

The patients will be subject to conventional clinical follow-up and at the same time benefit from the Bora care remote monitoring system. The Bora care remote monitoring system includes a BoraBand wristband measuring vital signs at home, the Bora Connect platform for caregiver visualization of data and the BVS3 score for early detection of COPD exacerbations. Patients are monitored daily remotely by Case Managers (nurses trained in Bora Care solution), who, when the BVS3 > 3 alert is triggered on Bora Connect, call the patient to inform the patient about his symptoms, then alert the pulmonologist by transmitting the information from Bora Connect and the minutes of the phone call, who, according to conventional management, decides whether or not to hospitalize the patient, or to generate an unscheduled consultation in order to prescribe drug treatment, and/or to prescribe additional examinations, and/or to adapt the patient's oxygen therapy prescription.

The Case Manager re-evaluates the situation after 48 hours and 96 hours if necessary and forwards the information to the pulmonologist. The nature of the transmission of information (telephone or email) between the Case Manager and the pulmonologist in case of an alert is defined when the patient is included by the pulmonologist. If desired, remotely monitored patients will be able to access the Bora Connect interface provided for patients (restricted viewing of data).

Inclusion Criteria:
