Allocating HIV prevention resources: a tool for state and local decision making.

The CDC provides funding for HIV prevention activities and state and local decision-makers must allocate these funds. The implementation of a resource allocation tool designed to facilitate this process that incorporates concepts of efficiency and equity as well as CDC mandates on the use of community planning groups is demonstrated, showing how information obtained from the resource allocation tool can be used to guide the policy analysis. The demonstration uses a simplified example based on data from Florida. The tool quantifies the inherent trade-offs associated with efficiency and equity and allows decision-makers to explore different ways of achieving equity. Given the underlying epidemiological model, results are not necessarily linear so common proportionality assumptions do not hold. However, a sense of equity can be provided by implementing various metrics allowing the policy maker flexibility in their decision process. By quantifying the impact of policy choices in terms of efficiency, cost, and distribution, the resource allocation tool makes the decision process more transparent and permits more informed choices.
