Review: inhaled corticosteroids do not reduce mortality but increase pneumonia in COPD
QUESTION
In patients with stable chronic obstructive pulmonary disease (COPD), what are the harms and benefits of inhaled corticosteroid (ICS) therapy?
REVIEW SCOPE
Included studies compared an ICS with placebo or other inhaled medications in patients ≥40 years of age with stable COPD. Outcomes were all-cause mortality at 1 and 3 years, pneumonia, and fractures.
