Frequent exacerbations (\u22653 per year) at baseline were associated with an increased risk of mortality (hazard ratio (HR) 3.23, 95% CI 1.39\u20137.50), severe exacerbations (HR 2.71, 95% CI 1.92\u20133.83), future exacerbations (incidence rate ratio (IRR) 3.08, 95% CI 2.36\u20134.01) and lung function decline. Coexisting COPD, dyspnoea and current cigarette smoking were similarly associated with a worse outcome across all end-points studied. Additional predictors of mortality and severe exacerbations were increasing age and cardiovascular comorbidity.
