Cost-Effectiveness Comparison between Ticagrelor and Clopidogrel in Acute Coronary Syndrome in Iran.

Background: The present study aimed to determine the cost-effectiveness of ticagrelor compared with clopidogrel in Iranian patients with acute coronary syndrome (ACS). Methods: A 1-year decision tree model combined with a 20-year Markov transition model was used to simulate the long-term cost and effectiveness of both ticagrelor and clopidogrel in Iran based on an Iranian payer's perspective. Clinical efficacy data were extracted from the PLATO trial and other published studies. Costs were estimated based on local prices in public sectors. Deterministic and probabilistic sensitivity analyses were used to test the robustness of base-case results over the uncertainties of model inputs. All calculations, analyses, and modeling were done in TreeAge 2011 and Microsoft Excel 2013. Results: Compared with clopidogrel, the treatment of Iranian ACS patients with ticagrelor for 20 years resulted in an additional cost of US$ 2.39 in a hypothetical cohort of 1000 patients. However, ticagrelor led to 7.2 quality-adjusted life-years (QALYs) gained per 1000 hypothetical patients. Accordingly, the estimated incremental cost-effectiveness ratio for this analysis was US$ 332.032 per 1 QALY gained. Conclusion: Ticagrelor was a cost-effective antiplatelet medicine compared with clopidogrel in Iranian patients with ACS. This could help Iran's policymakers to allocate resources more efficiently to ACS.
