Abstract

Background: The National HIV Behavioral Surveillance (NHBS) system is an ongoing behavioral surveillance system that was established by the Center for Disease Control and Prevention (CDC) in 2003 to assess trends in HIV risk behaviors, testing, and HIV prevention services among three groups. The NHBS system is used primarily in cities where approximately 60% of all cases of acquired immunodeficiency syndrome (AIDS) had been reported. Atlanta, GA is on this list. This evaluation will assess the efficaciousness of the implementation of the Georgia HIV Behavioral Surveillance (GHBS) System.

Purpose: The purpose of this study is to conduct an evaluation of the Injection Drug Use (IDU) component of the GHBS project. This evaluation has been designed to collect information on the logistics of the GHBS project, to address relevant evaluation questions, and to conduct a thorough assessment of the performance of the GHBS project.

Methods: The study used a mixed method approach. Qualitative methods consisted of conducting key informant interviews with relevant stakeholders. Quantitative methods consisted of sending out an electronic anonymous survey to local HIV/AIDS organizations. Lastly, the CDC's framework for surveillance systems was used to determine if the GHBS system met specific standards.

Results: Results from the study showed that the GHBS system has been successful with reaching enrollment goals. However, there are some issues with dissemination of data, costs, and representation. It was discovered that staff of local HIV/AIDS organizations are aware of the GHBS system but a small percentage of the staff utilize the data.

Conclusions: Information collected from the key informant interviews and electronic survey shows that overall, the surveillance project is operating successfully. However, there are some areas of concern such as representativeness, cost, and dissemination of data that need to be addressed to improve the efficacy of the surveillance project.
