Budget Impact Analysis of Single-Inhaler Fluticasone Furoate/Umeclidinium/Vilanterol in Patients with Asthma in the Dubai Academic Healthcare Corporation

Purpose: Asthma is a common, chronic respiratory disorder associated with substantial societal and economic burden globally, despite the availability of different treatment modalities. GSK has developed a once-daily single-inhaler triple therapy (SITT), comprised of fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI); a combination of inhaled corticosteroid, long-acting muscarinic antagonist, and long-acting β2-agonist for patients with uncontrolled asthma. A budget impact analysis was conducted to determine the financial impact of introducing FF/UMEC/VI SITT from the perspective of the Dubai Academic Healthcare Corporation (DAHC). Methods: A budget impact model was constructed using an epidemiology-based approach and used to estimate the expected 5-year budget impact of including FF/UMEC/VI for the treatment of eligible patients within the DAHC in the United Arab Emirates (UAE). The model included both pharmacy and efficacy-related costs. The perspective of the DAHC healthcare payer was adopted, thus only direct payer costs were included in the analysis. A one-way sensitivity analysis was conducted to test the robustness of the model structure, assumptions, and input parameters. Results: The total budget impact was estimated to save 1 million United States Dollars (USD) over 5 years, with budget impacts of 0.08 million USD in Year 1; 0.14 million USD in Year 2; 0.22 million USD in Year 3; 0.28 million USD in Year 4; and 0.33 million USD in Year 5. The overall budget impact per patient was estimated to save 12.2 USD over 5 years. In one-way sensitivity analyses, the budget impact was most sensitive to changes in the market uptake of FF/UMEC/VI. Conclusion: Healthcare payers may consider FF/UMEC/VI in the management of uncontrolled asthma which would save costs and reduce healthcare resource use in the UAE.
