  1. Pre-surveillance assessmentNew Strategies in HIV Surveillance Session V: Behavioral Surveillance Issues and AdvancesBangkok, Thailand Tobi Saidel and Virginia Loo Partnership for Epidemic Analysis March 2-5, 2009

  2. Topics covered in this talk • The role of the pre-surveillance assessment • The AHEAD framework: a new perspective on the PSA

  3. Purpose of surveillance • Understand where new infections are coming from • Understand the direction of the epidemic

  4. The surveillance cycle Identify a coordinating body Assess data needs and gaps for planning Agree on the purpose of surveillance Establish criteria for selecting populations and geographic areas Use data to guide response Conduct surveillance Gather information for decision-making Finalize population and geographic selection

  5. The pre-surveillance assessment informs decisions about … • Where and among whom HIV (behavioral and biological) surveillance surveys should occur • Methodologies for conducting such surveys

  6. What does AHEAD look at? A: Define Geographic Areas AREA B AREA C H: Identify High Risk Pops AREA D AREA E E: Estimate Size of Pops A: Assess Risk Behaviors D: Assess Level of Disease

  7. Summary • Resources for SGS are limited, so it is important to develop an epidemiologically driven process for prioritizing what type of data collection/analysis to do in which groups in which areas • Collecting all types of data everywhere is not an effective use of resources • The PSA can be reframed as part of staying AHEAD, specifically by: • Defining geographic units • Assessing what is known • Prioritizing further which data to collect

  8. THANK YOU!!!
