Overview of primary and secondary objectives of the AERIS study

LevelObjective
Primary▸ To estimate the incidence rate of all-cause AECOPD
▸ To estimate the incidence rate of AECOPD having sputum containing bacterial pathogens (overall and by species)
Secondary▸ To describe the proportion of overall and specific bacterial pathogens detected in sputum by severity of AECOPD
▸ To describe the proportion of overall and specific bacterial pathogens detected in sputum in stable COPD
▸ To estimate the incidence rate of AECOPD having sputum containing viral pathogens (overall and by species)
▸ To describe the proportion of overall and specific viral pathogens detected in sputum by severity of AECOPD
▸ To estimate the time elapsed between consecutive AECOPD episodes
▸ To assess the impact of all-cause AECOPD and stable COPD on health-related quality of life
▸ To assess the impact on healthcare use:
– Of all-cause AECOPD
– Of AECOPD having sputum containing bacterial pathogens
– Of AECOPD having sputum containing viral pathogens
  • AECOPD, acute exacerbations of chronic obstructive pulmonary disease; AERIS, Acute Exacerbation and Respiratory InfectionS in COPD.
