title: Treatment of uncomplicated Plasmodium falciparum malaria in Myanmar: a clinical decision analysis.
abstract: This study was undertaken to compare cost-effectiveness of three drug regimes for treatment of uncomplicated falciparum malaria in Myanmar. The alternative regimens in this study were chloroquine (CQ), sulphadoxine-pyrimethamine (SP) and mefloquine (MFQ) along with their therapeutic efficacy in Myanmar. The study was performed by modeling a clinical decision tree based on a hypothetical 1,000 adult uncomplicated falciparum malaria cases. Key variables were (i) three drug regimes: CQ, SP and MFQ, (ii) three categories of therapeutic efficacy of each drug: adequate clinical response (ACR), early treatment failure (ETF) and late treatment failure (LTF) according to the 1996 WHO protocol, and (iii) compliance with each drug. In structuring the model, necessary assumptions were made. The cost effectiveness was measured as cost per case cured and cost per case prevented death related to the provided drug, from the provider's perspective. According to the present price and therapeutic efficacy, SP is the most cost effective drug for a case cured in all three categories of efficacy (US$ 0.12 per case cured in ACR, US$ 0.38 per case cured in ETF and US$ 0.54 per case cured in LTF). For a case prevented death, CQ is most cost effective in all three categories (US$ 0.58 per case prevented death in the ACR, US$ 2.14 per case prevented death in the ETF and US$ 2.51 per case prevented death in the LTF). The lowest cost effective regimen is MFQ for both indicators of effectiveness at the present price and therapeutic efficacy. A sensitivity analysis was performed for sensitive values.
