title: Cost-effectiveness of Childbirth Strategies for Prevention of Mother-to-child Transmission of HIV Among Mothers Receiving Nevirapine in India.
abstract: BACKGROUND
  Mother-to-child transmission of HIV is an important mode of spread of HIV in India. With strategies like caesarian section and nevirapine therapy, this spread has been reduced. However, they have costs attached. In this context, this paper attempts to compare the cost-effectiveness of alternative childbirth strategies among HIV-positive mothers receiving nevirapine.
  
  
  METHODS
  Using sentinel surveillance data from three districts in Tamil Nadu, a model was created to test the cost-effectiveness of vaginal delivery against elective caesarian section among mothers receiving nevirapine. Sensitivity analysis was applied to evaluate cost per HIV infection prevented.
  
  
  RESULTS
  Vaginal delivery is not only cheaper in HIV-infected mothers receiving nevirapine but also cost-effective as compared to elective caesarian section. The incremental cost for preventing an additional HIV infection through caesarian section was Rs. 76,000. Sensitivity analysis reveals that the findings are robust over a range of HIV transmission probabilities, 0.04-0.14 for vaginal delivery and 0.00-0.02 for caesarian section.
  
  
  CONCLUSIONS
  From a clinical perspective, the findings suggest that pregnant HIV-infected women receiving nevirapine should consider the benefits of a cheaper and safer vaginal delivery. From an economic perspective, the findings support the strategy of vaginal delivery in mothers receiving nevirapine.
