Objectives: The Salford Lung Study in Chronic Obstructive Pulmonary Disease (SLS COPD) is a 12-month, open-label randomized clinical trial comparing clinical effectiveness and safety of initiating once-daily fluticasone furoate/vilanterol (FF/VI) 92/22 mcg with continuing usual care (UC) in patients with COPD followed in primary care in the UK. The objective of this analysis is to estimate the economic impact of these results when applied to Spain.
Materials and methods: An Excel-based cost–consequence model with a one-year time horizon was populated with SLS COPD results, adopting the Spanish National Health System (NHS) perspective. Patients analyzed were diagnosed COPD patients ≥40 years old, currently managed with maintenance treatment and with a history of exacerbations (total number estimated from Spanish data). Mean least squares annual rates of moderate/severe exacerbations after 1 year for the intention-to-treat population from SLS COPD were included in the model (1.50 [FF/VI] and 1.64 [UC]); serious adverse events were excluded from the analysis as no differences between treatment arms were found. Medication and exacerbation management costs in euros were estimated from Spanish public sources for 2016. Model base-case analysis assumed an increased usage of FF/VI from 4% to 10% within 1 year, and a 100% proportion of days covered with study medications. Deterministic sensitivity analyses were performed for mitigating uncertainty.
Results: At base case, within 50,522 COPD patients analyzed, substitution of UC with FF/VI 92/22 mcg was associated with reduced medication and exacerbation management costs, leading to potential total annual savings of €353,623. Deterministic sensitivity results ranged from €218,333 up to €1,532,366 potential cost savings associated with FF/VI, showing the robustness of base-case results.
Conclusion: The decreased rate of exacerbations with FF/VI 92/22 mcg compared with UC observed in SLS COPD could be translated into potential health care savings for the Spanish NHS. These results may be useful to inform decision-making processes.
