AIDS cost modeling in the U.S.: a pragmatic approach.
Sophisticated modeling of the economic impact of AIDS remains a future goal rather than a present reality due to a lack of data. However, policy makers with responsibility for implementing AIDS-related programs have an immediate need for estimates of service utilization and costs. In this paper we describe a microcomputer-based planning model which is structured to reflect the 'epidemic of epidemics' nature of AIDS. In the process of constructing this model, deficiencies in existing data sources have become evident. The second part of the paper describes research issues and priorities for improving data used to estimate the cost of AIDS.
