Abstract:
|
The Centers for Disease Control and Prevention is using a three-stage cluster sampling approach to implement a national clinical surveillance system of adults in care for HIV infection. The first stage sample of 20 states was selected using systematic probability proportional to size (PPS) sampling based on AIDS prevalence at the end of 2002. Although the HIV/AIDS Reporting System (HARS) is a near census of persons diagnosed with AIDS, no national or state list of persons in care for HIV infection exists to serve as a second-stage sampling frame for such individuals. Instead, a second stage sampling frame of HIV care facilities will be constructed in each state and patients will be sampled randomly from selected facilities in the third stage of sampling. Each state tracks facilities that report HIV cases and will use this as a starting point for the second-stage sampling frame. Methods to increase the completeness of this list prior to sampling by supplementing it with facilities from other sources---such as Medicaid, laboratory reporting databases, and HIV medicine society membership lists---and issues related to obtaining a measure of size for PPS sampling will be discussed.
