Assessing the efficiency of HIV prevention around the world: methods of the PANCEA project.

There is wide agreement that an effective response to the global HIV epidemic requires very substantial resources. This consensus has been partially translated into increasing contributions to combat the epidemic (UNAIDS 2004). The need to spend this money efficiently can hardly be overstated: the lives of millions depend upon how effectively available funds are allocated. Available studies on the cost and cost-effectiveness of HIV prevention programs in developing countries are very limited in number, as well as in the range of prevention strategies and geographic settings examined (Marseille, Hofmann, and Kahn 2002). “Prevent AIDS: Network for Cost-Effectiveness Analysis” (PANCEA), is a three-year, five-country study funded by the U.S. National Institutes of Health. It has the purpose of providing essential information and analysis for an improved allocation of HIV prevention funds in developing countries. The study includes five countries: India, Mexico, Russia, South Africa, and Uganda. This article reviews PANCEA's data collection methods. Our purpose is two-fold. First, we aim to explicate the methods and data sources used in PANCEA. Second, we want to give other health services researchers sufficient information to judge the potential suitability of adapting PANCEA's approach to their own efforts. Further details on the project and key documents (e.g., instruments) can be found in the online-only Appendix to this article available at http://www.blackwell-synergy.com, at the PANCEA link at http://hivinsite.ucsf.edu/InSite?page=pancea, and from the authors. The remainder of the paper addresses PANCEA's conceptual approach, data collection tools, data collection process, challenges and limitations, early findings, and applications for other health program assessments.
