Patients admitted for a severe exacerbation of COPD that required NIV or invasive ventilation or high flow therapy will be screened for the trial once they reach clinical stability that allow weaning of NIV, invasive ventilation, or high flow therapy.
The screening visit will take place during a standard consultation between 2 days following admission for acute hypercapnic respiratory failure and no later than 30 days following the discharge from the acute ward.
The inclusion visit will be performed no later than 30-days following discharge from the acute ward.
Follow-up visits will be performed at 3, 6 months after inclusion with a +/-14 days window.
Visits will be conducted in the hospital unless patient is unable to attend due to medical condition or healthcare crisis (infectious pandemic for example). In that case, a remote consultation will be performed to retrieve data available without physical attendance.
