A cost threshold analysis of ciprofloxacin-dexamethasone versus ofloxacin for acute otitis media in pediatric patients with tympanostomy tubes.
OBJECTIVE: The aim of this study was to determine the cost-effectiveness hreshold of a ciprofloxacin 0.3% and dexamethasone 0.1% (CD) otic suspension relative to olfloxacin otic solution (OFX) for the treatment of acute otitis media in pediatric patients with tympanostomy tubes (AOMT). METHODS: This study used a decision-analytic model to simulate the costs and consequences of the ototopical treatment of AOMT. The AOMT model consisted of 3 tiers of antimicrobial therapy. Each successive tier represented the repeat treatment of clinical failures from the preceding tier. Patients were modeled for treatment until cured or until third-tier therapy was complete, at which time patients were considered cured. First-tier therapy modeled a comparison of CD and OFX using efficacy rates taken from a randomized clinical trial with a population of 599 patients. Second-tier therapy modeled the use of amoxicillin and clavulanic acid using an efficacy rate taken from the medical literature. Third-tier therapy was modeled as being pathogen specific and could follow 1 of 3 possible clinical pathways: (1) PO fluconazole, (2) IM ceftriaxone, or (3) IV antibiotics administered in a hospital setting. Third-tier therapeutic pathway probabilities were based on the microbiologic spectrum of the treatment failures from the clinical trial. Cost information (in year-2003 US dollars) was taken from accepted cost reference sources and presented from the perspective of a third-party payer. The economic outcome of interest was the cost-effectiveness threshold of CD relative to OFX. RESULTS: Given the model parameters, CD had a cost-effectiveness threshold value of 4.5 times the wholesale acquisition cost of OFX. Based on actual cost, first-tier CD therapy was more cost-effective than OFX up to a threshold price of US 152.64 dollars. CONCLUSION: In this decision-analytic model, CD was more cost-effective than OFX for AOMT therapy in pediatric patients up to a threshold price of 4.5 times the price of OFX.[1]References
