Chronic Airway Disease, Mucus Rheology and Exacerbations: a Randomized Controlled Trial of COPD Patients
The main objective of this trial is to compare the exacerbation number over 12 months of follow-up between a group of patients with COPD treated according to standardized management (azithromycin prescribed in the event of severe sputum according to the CASA-Q score , standardized comparator arm) and a similar group in which azithromycin is prescribed based on mucus rheology (experimental arm) or CASA-Q.
