Abstract

MEJIA, Aurelio et al. Analysis of cost effectiveness of prasugrel compared with clopidogrel for patients with acute coronary syndrome undergoing percutaneous coronary intervention in Colombia. Acta Med Colomb [online]. 2015, vol.40, n.4, pp.310-317. ISSN 0120-2448.

Objective: to determine the cost-effectiveness relation of prasugrel compared with clopidogrel for the treatment of adult patients with acute coronary syndrome from the perspective of Colombian health system. Material and methods: a Markov model with annual cycles in which patients can remain without experiencing new cardiovascular events, have a new event or die, was built. In the base case a time horizon of 10 years and a discount rate of 3% was adopted. Transition probabilities were taken from the clinical trial TRITON-TIMI 38, of vital statistics from the National Department of Statistics and from the information of Colombian patients in ACCESS registry. To identify and measure the use of resources, a typical case was designed from the review of guidelines and protocols; Colombian tariff manuals were used for assessment. Deterministic and probabilistic sensitivity analyzes were performed. Results: in the base case, the cost per year of quality-adjusted life gained with prasugrel is $ 79,987,695 Colombian pesos. The results are sensitive to changes in the timeframe and cost of clopidogrel. Under a threshold willingness to pay three times the per capita GDP of Colombia, the probability that prasugrel may be cost-effective, is 7%. Conclusions: the decision on the inclusion of prasugrel in the treatment of patients with acute coronary syndrome undergoing percutaneous coronary intervention depends mainly on the cost of clopidogrel that the decision maker considers relevant to perform the comparison.
