This study evaluated the impact of prompt versus delayed initiation of single-inhaler TT (fluticasone furoate, umeclidinium, and vilanterol [FF/UMEC/VI]) following a COPD exacerbation.Patients and Methods: This retrospective cohort study used data from the IQVIA PharMetrics® Plus database. Patients initiating FF/UMEC/VI following a COPD exacerbation between September 18, 2017 and September 30, 2019 (exacerbation = index date) were categorized as prompt (within 30 days of index) or delayed (31– 180 days after index) FF/UMEC/VI initiators. Patients were aged ≥ 40 years at index, had ≥ 12 months’ continuous health insurance coverage before index (baseline), and ≥ 6 months’ coverage after index (follow-up). Patients with a COPD exacerba
