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

BackgroundCompared with multiple-inhaler triple therapy (MITT), single-inhaler triple therapy (SITT) with fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) demonstrated improved lung function and meaningful improvements in chronic obstructive pulmonary disease (COPD) Assessment Test score.

Zusammenfassung:BackgroundCompared with multiple-inhaler triple therapy (MITT), single-inhaler triple therapy (SITT) with fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) demonstrated improved lung function and meaningful improvements in chronic obstructive pulmonary disease (COPD) Assessment Test score. This real-world study compared the effectiveness of switching patients with COPD in England from MITT to once-daily SITT with FF/UMEC/VI by evaluating rates of COPD exacerbation, healthcare resource use (HCRU) and associated direct medical costs.MethodsRetrospective cohort pre-post study using linked primary care electronic health record and secondary care administrative datasets. Patients diagnosed with COPD at age ≥35 years, with smoking history, linkage to secondary care data and continuous GP registration for 12 months pre-switch and 6 months post-switch to FF/UMEC/VI were included. Index date was the first initiation of an FF/UMEC/VI prescription immediately following MITT use from 15 November 2017 to 30 September 2019. Baseline was 12 months prior to index, with outcomes assessed 6/12 months pre-switch and post-switch, and stratified by prior COPD exacerbation status.ResultsWe included 2533 patients (mean [SD] age: 71.1 [9.9] years; 52.1% male). In the 6 months post-switch, there were significant decreases in the proportion of patients experiencing ≥1 moderate-to-severe (36.2%–28.9%), moderate only (24.4%–19.8%) and severe only (15.4%–11.8%) COPD exacerbation (each, p
