Outcomes of patients with COPD switching from multiple-inhaler to once-daily single-inhaler triple therapy in a real-world primary care setting in England: a retrospective pre-post cohort study.

Patients with COPD switching from MITT to once-daily SITT with FF/UMEC/VI in a primary care setting had significantly fewer moderate and severe exacerbations, and lower COPD-related HCRU and costs, in the 6 months post-switch compared with the 6 months pre-switch.
