However, this effect may have been influenced by the forced withdrawal of inhaled corticosteroids (ICS) at randomization. We used an adaptive selection new-user design to compare single-inhaler triple therapy with dual bronchodilators in real-world clinical practice.Patients and Methods: We identified a cohort of COPD patients, 40 years or older, treated during 2017– 2020, from the United Kingdom’s Clinical Practice Research Datalink, a real-world practice setting. ICS-naïve patients initiating single-inhaler triple therapy or dual bronchodilators were compared on the incidence of COPD exacerbation and pneumonia over one year, after adjustment by propensity score weighting.Results: The cohort included 4106 new users of single-inhaler triple therapy and 29,702 of dual bronchodilators. Single-inhaler triple therapy was the first maintenance treatment in 44% of the users and 43% had no COPD exacerbations in the prior year. The adjusted hazard ratio (HR) of a first moderate or severe exacerbation with triple therapy relative to dual bronchodilators was 1.08 (95% confidence interval (CI): 1.00– 1.16). Among patients with two or more prior exacerbations the HR was 0.83 (95% CI: 0.74– 0.92), while for those with prior asthma diagnosis it was 0.86 (95% CI: 0.70– 1.06) and with blood eosinophil count > 300 cells/μL it was 0.89 (95% CI: 0.76– 1.05). The incidence of severe pneumonia was increased with triple therapy (HR 1.50; 95% CI: 1.29– 1.75).Conclusion: In a real-world setting of COPD treatment among ICS-naïve patients, thus unaffected by ICS withdrawal, single-inhaler triple therapy was not more effective than dual bronchodilators at reducing the incidence of exacerbation, except among patients with multiple exacerbations. Single-inhaler triple therapy should be initiated mainly in patients with multiple exacerbations while, for most others, dual bronchodilators are just as effective whilst avoiding the excess risk of severe pneumonias.Keywords: cohort studies, COPD exacerbation, pneumonia, propensity scores, real-world evidence |
