While restricting the overuse of inhaled corticosteroids (ICS) may influence healthcare utilization required to treat inadvertent respiratory (exacerbations and pneumonia) and diabetes-related events, it may also change the total medication cost. This analysis was performed to estimate the 5-year budget impact of switching from ICS-containing treatment combinations to dual bronchodilation, in line with the recommendations. Methods: The model quantified the budget impact of treatment and healthcare resource utilization when COPD patients were anticipated to switch from ICS-containing treatments to dual bronchodilation. Three switch scenarios were calculated with increasing proportions of patients on dual long-acting bronchodilators, to the detriment of ICS-containing double and triple combinations. Clinical and cost input data were based on results from clinical trials and Greek and Portuguese healthcare cost databases. Results: Healthcare resource use to manage exacerbations, pneumonia and diabetes-related events were projected to increase between 2019 and 2023 in parallel with the growing COPD patient population and associated costs were estimated at 52–57% of the total disease cost in the Greek and Portuguese base case scenarios. Total cost savings between 21 and 112million EUR were projected when the proportion of patients on double and triple ICS-containing treatments was gradually reduced to 50% in scenario A, 20% in scenario B and 7% in scenario C. Sensitivity analyses showed that none of the model assumptions had a major impact on the projected savings. Conclusion: The alignment of COPD treatment with current recommendations may bring clinical benefits to patients, without substantial cost increases and even cost savings for payers.The authors disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: The study was funded by Boehringer Ingelheim.info:eu-repo/semantics/publishedVersio
