Cost-effectiveness analysis of thermotherapy versus pentavalent antimonials for the treatment of cutaneous leishmaniasis

Abstract

Introduction: The treatment of cutaneous leishmaniasis is toxic, has contraindications and a high cost. Objective: To estimate the cost-effectiveness of thermotherapy versus pentavalent antimonials for the treatment of cutaneous leishmaniasis. Methods: Effectiveness was the proportion of healing, and safety with the adverse effects; these parameters were estimated from a controlled clinical trial and a meta-analysis. A standard costing were conducted. Average and incremental cost-effectiveness ratios were estimated. The uncertainty regarding effectiveness, safety and costs was determined through sensitivity analyses. Results: The total costs were $66,807 with Glucantime and$14,079 with thermotherapy. The therapeutic effectiveness rates were 64.2% for thermotherapy and 85.1% for Glucantime. The average cost-effectiveness ratios ranged between $721 and$1,275 for Glucantime and between $187 and$390 for thermotherapy. Based on the meta-analysis thermotherapy may be a dominant strategy. Conclusion: The excellent cost-effectiveness ratio of thermotherapy shows the relevance of its inclusion in guidelines for the treatment
