Impact of Air Quality on Exacerbations of COPD in the Somme (PolluBPCO)

July 13, 2020 updated by: Centre Hospitalier Universitaire, Amiens
All COPD patients with a diagnosis of acute exacerbation in emergency room in University Hospital of Amiens-Picardie between 01/01/2017 and 31/12/2017. The investigator will collect for each patient the home address and the work address. The duration of 1 year was chosen to take into account seasonal variations.
