  1. Surveillance of HIV & Behaviors Among Drug Users: ObservationsT. Stephen Jones, MDInter-country Consultation on Preventing HIV among IDUsScaling Up: From Evidence to Action April 11, 2007 – Kolkata, India

  2. Topics – 1 Review how the CDC is implementing BSS for drug users in the USA

  3. Topics – 2 HIV surveillance of IDUs; the key role of formative and qualitative studies

  4. Topics – 3 How many IDUs? A precise answer is usually not found

  5. Topics – 4 Two challenges to HIV surveillance (& prevention) for IDUs: • drug user stigma • ignorance of how drugs are used

  6. Topics – 5 HIV Behavioral surveillance of IDUs: • How to do it • Where to do it • What data to collect

  7. National HIV Behavioral Surveillance System (NHBS), USA NHBS monitors HIV risk behaviors among: • Men who have sex with men (MSM) • Injection drug users (IDU) • Heterosexuals at risk of HIV infection (HET) Source: adapted from slides provided by Dr. Abu Abdul-Quader, CDC

  8. National HIV Behavioral Surveillance System, USA: Objectives To assess: • Prevalence of & trends in HIV risk behaviors • Prevalence of & trends in HIV testing behaviors • Use of HIV prevention services Source: adapted from slides provided by Dr. Abu Abdul-Quader, CDC

  9. National HIV Behavioral Surveillance System, 25 City Sites, USA, 2005 Seattle Boston New Haven Detroit Nassau New York City Newark Chicago San Francisco Philadelphia Baltimore Denver Las Vegas Washington, DC St. Louis Norfolk Los Angeles San Diego Atlanta Dallas Houston New Orleans Ft. Lauderdale Miami San Juan Source: adapted from slides provided by Dr. Abu Abdul-Quader, CDC

  10. Overall National HIV Behavioral Surveillance System Strategy, USA • Conducted in 12-month cycles (MSM, IDU, HRH) • Same 25 cities • Standardized questionnaires • Consistent eligibility criteria • Over 18 years of age • Resident of city • 500 persons/city will be interviewed during each cycle Source: adapted from slides provided by Dr. Abu Abdul-Quader, CDC

  11. National HIV Behavioral Surveillance System, IDUs, USA Respondent driven sampling (RDS) methodology was selected.

  12. Importance of Qualitative, “Open ended” Studies for HIV Surveillance of IDUs

  13. International Rapid Assessment Response and Evaluation, Cambodia, 2004 • 180 participants • 84 Key Informants: • Drug users (n = 66) • Service providers (n = 11) • Policy makers (n = 6) • 18 Focus Groups • 77 Observations & Mapping CDC provided training & technical assistance Source: adapted from K O’Connell, report of I-RARE in Cambodia

  14. Injection equipment is stored in public places for later use, I-RARE, Cambodia “After the last person finishes injecting, they clean the syringe and needle again and keep them in a brick hole for the next use”.21 year old IDU IDU Syringe Source: adapted from K O’Connell, report of I-RARE in Cambodia

  15. Qualitative Studies for HIV Surveillance among IDUs • Important early step to guide planning of IDU surveillance • Critical in mapping high risk groups (HRG) such as IDUs • Should be repeated periodically to detect new drug use patterns

  16. Qualitative Studies for HIV Surveillance among IDUs (2) • Requires special skills • UNODC-sponsored Rapid Situation Assessments (RSAs) are a rich source of qualitative data • Personal stories and pictures may help motivate “decision makers”

  17. How Many IDUs?

  18. How Many IDUs? • Qualitative knowledge of drug users helps in mapping and estimating number of IDUs • Multiple estimation methods available • Multipliers, capture recapture, etc. • A “soft” estimate best stated with “high” “low” range • See UNAIDS guide http://data.unaids.org/Publications/External-Documents/EstimatingPopSizes_en.pdf

  19. Two Barriers to High Quality, Effective HIV Surveillance (& Prevention) for IDUs • Wide-spread negative views of drug users • Limited understanding of drug user culture & how drugs are prepared & used

  20. “Addictphobia” • “Addictphobia” is a short name for the stereotypes, stigmas, and negative attitudes about people who use drugs. • Similar to “homophobia” and “racism” which are important social and individual factors that influence the success of prevention activities. Source: adapted from Jones TS & Anderson T. Abstract 316, 1999 National HIV Prevention Conference, Atlanta GA USA

  21. Stigma “Gallery” Addictphobia Racism Sexism Homophobia

  22. Most of the People Working On HIV Surveillance (& Prevention) for Drug Users Have Limited Initial Understanding of Drug Use

  23. HIV Surveillance (& Prevention) Staff Need to Understand Drug Use • Qualitative studies help • Include drug users in the planning and carrying out IDU surveillance • Training about drug use & injection • Use observations & descriptions of how drug users prepare and inject drugs (Koester) & peer outreach teams • US National HIV Behavioral Surveillance System IDU study used several hours of video of drug users preparing & injecting drugs

  30. HIV Behavioral Surveillance of IDUs How to do it Where to do it What data to collect

  31. HIV Behavioral Surveillance for IDUs: How to Do It • Sampling options • Respondent driven sampling (RDS) • Snowball/network sampling • Targeted sampling • Time location

  32. HIV Behavioral Surveillance for IDUs: Where to Do It • Selecting locations • Qualitative studies and mapping identify where to find IDUs • Special studies in prisons

  33. HIV Behavioral Surveillance for IDUs: How to Do It • Plan for repeated surveys using standard sampling and questions so that trends can be followed • Plan realistically based on funding and other critical resources (trained workers) • Standardized questionnaires can have 50-100 questions

  34. Behavioral Surveillance for IDUs:What Data to Collect • Demographic • Knowledge Attitudes • Risk behaviors: • drugs used, • how drugs prepared and used & sharing • sexual behaviors, risks & condom use • Arrest & jail/prison

  35. Behavioral Surveillance for IDUs:What Data to Collect – Program Services • Exposure to and use of prevention & treatment services • Peer outreach • Opioid substitution treatment • Drop-in centers • Needle syringe programs • Essential to monitor success in reaching large numbers of at-risk IDUs (“going to scale”)

  36. Useful Resources • UNAIDS – Epidemiologic Publications on HIV Surveillance http://www.unaids.org/en/HIV_data/Epidemiology/epipublications.asp • FHI – Guidelines for Repeated Behavioral Surveys in Populations at Risk of HIV http://www.fhi.org/en/HIVAIDS/pub/guide/bssguidelines.htm
