title: Optimizing resource allocation for HIV/AIDS prevention programmes: an analytical framework.
abstract: BACKGROUND
  Although investment in HIV/AIDS prevention has increased worldwide, it remains uncertain how the additional resources can be most efficiently allocated to maximize the number of infections averted, especially at the country, regional and local levels.
  
  
  METHODS
  Data from developing countries in Africa, Asia and Latin America were reviewed on the allocation of HIV/AIDS prevention funds in relation to the prevalence of infection, as well as budgetary allocations for specific population groups at high risk of infection, such as sex workers, intravenous drug users and men who have sex with men. The variation in unit costs of voluntary counselling and testing in five countries was also examined.
  
  
  RESULTS
  Evidence was found of three distinct sources of inefficiency in the allocation of HIV/AIDS prevention resources: inefficiency in the mix of interventions selected; inefficient targeting of key populations; and technical inefficiency in the production of HIV prevention services.
  
  
  CONCLUSIONS
  A general conceptual framework for evaluating the efficiency of HIV/AIDS prevention programmes at the country, regional and local levels is proposed. This framework stresses three equally important components of programme efficiency: cost-effectiveness (the choice of the mix of interventions); targeting (the choice of the mix of target populations); and technical efficiency (the delivery of prevention services at least cost).
