Sažetak
BACKGROUND & METHODS: Economic evaluation in genomic medicine is an emerging discipline to assess the cost-effectiveness of genome-guided treatment. Here, we developed a pharmaco- economic model to assess whether pharmacogenomic (PGx)-guided warfarin treatment of elderly ischemic stroke patients with atrial fibrillation in Croatia is cost effective compared with non-PGx therapy. The time horizon of the model was set at 1 year. RESULTS: Our primary analysis indicates that 97.07% (95% CI: 94.08-99.34%) of patients belonging to the PGx- guided group have not had any major complications, compared with the control group (89.12% ; 95% CI: 84.00-93.87%, p < 0.05). The total cost per patient was estimated at €538.7 (95% CI: €526.3-551.2) for the PGx-guided group versus €219.7 (95% CI: €137.9-304.2) for the control group. In terms of quality-adjusted life-years (QALYs) gained, total QALYs was estimated at 0.954 (95% CI: 0.943-0.964) and 0.944 (95% CI: 0.931-0.956) for the PGx-guided and the control groups, respectively. The true difference in QALYs was estimated at 0.01 (95% CI: 0.005-0.015) in favor of the PGx-guided group. The incremental cost-effectiveness ratio of the PGx-guided versus the control groups was estimated at €31, 225/QALY. CONCLUSION: Overall, our data indicate that PGx-guided warfarin treatment may represent a cost- effective therapy option for the management of elderly patients with atrial fibrillation who developed ischemic stroke in Croatia.
