Air pollution, inhaled therapy and COPD exacerbations in Yunlin, Taiwan: a 2016–2024 single-centre retrospective cohort with environmental and carbon-footprint analyses
In this single-centre retrospective study, higher ambient PM<sub>2.5</sub> was associated with higher COPD acute exacerbation (AE) rates, and greater use of triple therapy correlated with lower hospitalisations. Our inhaler carbon-footprint estimates quantify GHG differences between device types but were not linked to AE and should inform sustainability discussions rather than clinical effectiveness.
