Study design details

Main study objective

-Compare the effectiveness (in terms of moderate and severe exacerbation prevention) of prescribing inhaler devices with similar inhalation techniques vs prescribing devices with dissimilar inhalation techniques in patients with COPD −Assess therapy adherence in patients with COPD prescribed inhaler devices with similar inhalation techni

Outcomes

•Moderate and severe COPD exacerbation rate (sensitivity definition), •Short-acting beta2agonist (SABA) use•Adherence to COPD therapy

Data analysis plan

Phase 2 of the study will investigate the effectiveness of comparable vs. non-comparable devices (as categorised in phase 1) in terms of excaerbation rate, SABA use and adherence to COPD therapy.
