Economic analysis at the global level: a resource requirement model for HIV prevention in developing countries

Agencies operating at the international level have a need for economic analysis to help develop global health policies and determine resource requirements to support their advocacy efforts. This paper presents work commissioned by the Global Programme on AIDS to estimate the total resource requirements of implementing a package of HIV prevention strategies in developing countries. The modelling approach identified a hypothetical package which should be implemented and developed a set of assumptions relating the size, number and coverage of programmes required for each strategy to a set of demographic and other characteristics of individual countries. Costs were attached to estimate the total costs of the package for individual countries, regions and the developing world. Results are presented for regions and their implications discussed. Conclusions are drawn on the value of this type of modelling approach to estimating resource requirements.
