Air Pollution and COPD Exacerbation

Overview

There is an excess of hospitalization rates for acute exacerbation of COPD in Picardy compared to the national data. A first study realized in Picardy has shown a link between air quality and COPD. Nevertheless, the particles type is unknown and according to it, impact on COPD could be different. The investigator goal is to find a correlation between acute exacerbation of COPD consultation rate and daily ultra thin particles in Haut de France. The investigators will correlate the particles composition with daily acute exacerbation of COPD rate. All COPD patients with a diagnosis of acute exacerbation in emergency room in University Hospital of Amiens-Picardie and Lille, and Clinique de l'Europe between 01/01/2020 and 31/12/2020 will be included. For each patient, home and work address will be collected. The duration of 1 year was chosen to take into account seasonal variations. In parallel, a daily report of the rate of ozone, particles (PM2.5 and PM10), dioxide nitrogen but also odours and pollens will be done by ATMO Haut de France.
