The impact of exacerbations in COPD

Author: Sanofi Editorial Team

COPD exacerbation risk has been shown to accelerate after each exacerbation.2,a 

Exacerbation risk accelerates after each exacerbation2

*Severe exacerbations were defined as those which resulted in hospitalisation with a primary discharge diagnosis of COPD2

Despite triple inhaled therapyc, many patients remain symptomatic as defined by persistent symptoms and exacerbations.2

COPD exacerbations may lead to an accelerated rate of decline in lung function3,d

  • Rate of FEV1 decline nearly double3

  • Lung function decline may occur after only one COPD exacerbation3

aBased on data from a large population-based cohort of 73,106 Canadian patients (mean age 75 years) who were hospitalised for the first time because of a severe exacerbation of COPD (1990-2005, followed until death or March 31, 2007). The hazard functions of successive hospitalised COPD exacerbations and all-cause mortality over time were estimated, and HRs adjusted for age, sex, calendar time and comorbidity. 2
bAdjusted for age, sex, calendar time, and the modified Chronic Disease Score.2
cOr double inhaled therapy if ICS is contraindicated.4
dFEV1 decline after a single moderate-to-severe exacerbation. Based on a retrospective analysis of data from 586 patients with moderate-to-severe COPD.3 

aHR, adjusted hazard ratio; COPD, chronic obstructive pulmonary disease; FEV1, forced expiratory volume in 1 second; QoL, quality of life
