Objective: To assess cost-effectiveness of antifungal treatment on patients with persistent fever neutropenia: empiric antifungal therapy (EAT) vs. anticipated antifungal therapy (AAT). Methods: A decision model was performed to evaluate the cost-effectiveness of antifungal treatment strategies in patients with febrile neutropenia not responding to a broad spectrum antibiotic treatment. The strategies included were: 1) EAT with amphotericin B deoxycholate; 2) EAT with liposomal amphotericin B; 3) EAT with caspofungin; and 4) AAT with voriconazole and amphotericin B deoxycholate or liposomal amphotericin B or caspofungin in patients who initiate treatment despite having negative CT scan and galactomannan or fail to voriconazole. Effectiveness was measured as the number of deaths averted. Cost-effectiveness and incremental cost-effectiveness ratios were calculated. Deterministic and probabilistic sensitivity analyzes were performed. Results: EAT with Amphotericin B deoxycholate was the least expensive and least effective strategy. The EAT with caspofungin was the most effective. The cost per death averted for caspofungin when compared with amphotericin B deoxycholate was $17,011,073.83, which would indicate that this strategy would be cost-effective for the country if the willingness to pay per death averted is equal to or greater than this value. EAT with liposomal amphotericin B and AAT with voriconazole were dominated by AET with caspofungin, which is less costly and more effective. Conclusions: EAT with caspofungin would be cost-effective for Colombia if the threshold per death averted is greater to $18.000.000. If the threshold is lesser the EAT with amphotericin B deoxycholate would be the election. © 2012 International Society for Pharmacoeconomics and Outcomes Research (ISPOR).
