Aim: Determine whether using CYP2C19 genotype to optimize antiplatelet therapy selection is cost effective over the initial 30 days and 1-year following percutaneous coronary intervention. Materials & methods: A cost-effectiveness analysis compared 30-day and 1-year outcomes and cost across three treatment strategies (universal clopidogrel, universal prasugrel, genotype-guided) in a hypothetical cohort. Results: Base-case scenario results at 30 days indicated that the incremental cost per major cardiovascular or bleeding event avoided for genotype-guided treatment was US8525 and US42,198 compared with universal clopidogrel and prasugrel, respectively. Probabilistic sensitivity analysis demonstrated that genotype-guided treatment was cost effective over 30 days and 1 year in 62 and 70% of simulations, respectively. Conclusion: Implementing a CYP2C19 genotype-guided approach to antiplatelet therapy could have a positive economic impact by preventing readmissions following percutaneous coronary intervention.
