Using HIV Surveillance Data to Inform the ECHPP Evaluation

  1. 1. Using HIV Surveillance Data to Inform the ECHPP Evaluation Holly H. Fisher and Tamika Hoyte 2011 National HIV Prevention Conference Atlanta, GA National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention Division of HIV/AIDS Prevention
  2. 2. OVERVIEW
  3. 3. Overview ECHPP background and rationale ECHPP evaluation plan Data triangulation and synthesis Questions and discussion
  5. 5. ECHPP description Three-year project (Sept. 2010 to Sept. 2013) implemented by health depts in 12 MSAs with highest AIDS burden Project objectives  Develop an enhanced plan that aligns the jurisdiction’s prevention and care activities with NHAS  Identify/implement optimal combination of prevention, care, and treatment activities  Implement activities at appropriate scale  Increase targeting of highest risk groups
  6. 6. * Enhanced Comprehensive HIVPrevention Plans (ECHPP) project

  11. 11. ECHPP evaluation Program processes Communit y-level outcomes Communit y-level impact
  12. 12. Program Processes ECHPP activities will be monitored throughout implementation period to track delivery of services and programs Were services and programs delivered as intended? What were challenges and successes?
  13. 13. Program Processes Local and core monitoring  Grantees will report: • progress on local objectives to project officers (quarterly) • standardized, core process measures to evaluation team (semi-annually) Monitoring of other publicly-funded prevention, care, and tx activities in 12 MSAs Collection of qualitative and contextual data
  14. 14. Communit y-level outcomes Outcomes will be monitored to determine extent to which changes are associated with ECHPP implementation Did risk behaviors among priorit y populations decrease over time? Did service access and overall health outcomes improve among priorit y populations over time?
  15. 15. Communit y-level outcomes Request data annually from CDC clinical and behavioral surveillance data systems  Medical Monitoring Project (MMP) • HIV-diagnosed ppl currently receiving HIV medical care • Information re: access to care, HIV treatment and adherence, risk behaviors, health conditions, and prevention activities • Available in 9 MSAs
  16. 16. Communit y-level outcomes Request data annually from CDC clinical and behavioral surveillance data systems  National HIV Behavioral Surveillance (NHBS) • MSM, IDU, and high-risk heterosexuals • Information re: HIV testing and treatment experiences, risk behaviors, health conditions, and prevention activities • Available in all 12 MSAs  (New) MSM Web Surveillance Project • MSM • Information similar to NHBS survey + items re: stigma and discrimination, partner risk • Respondents will be linkable to all 12 MSAs
  17. 17. Communit y-level outcomes Collect supplemental data in six cities at beginning/end of ECHPP  Clinic survey • 200 HIV-diagnosed ppl in care per MSA, per time point • Modeled after MMP  Community survey • 100 high-risk heterosexuals, 100 IDUs per MSA, per time point • Modeled after NHBS
  18. 18. Communit y-level impact Track changes in HIV incidence, health outcomes, and disparities over time Was there a reduction in HIV incidence or indicators of risk over time? Was there an increase in, and impact of, prevention and care for ppl living with HIV/AIDS over time? Was there a reduction in HIV/AIDS disparities over time?
  19. 19. Communit y-level impact Request data annually from eHARS (U.S. case surveillance system)  Case surveillance data Incidence surveillance data Will also look at long-term outcomes from clinical and behavioral surveillance systems to assess impact
  20. 20. ECHPP activity categories Program processesa For all tests, healthcare and non- healthcare settings: o # of HIV-positive tests o # of newly-identified, conf. HIV- positive tests o % of newly-identified, conf. HIV- HIV testing positive tests o % of newly-identified, HIV-positive tests (separately for prelim. and conf. positive tests) where client was referred to: • HIV medical care • Partner services • Prevention servicesNOTE: Indicator data will be computed separately for each priority population, where possiblea Process data = Program information reported semi-annually by grantees to CDC and other federal agencies ; represents publicly-fundedservices provided in the MSA
  21. 21.

  23. 23. Data triangulation and synthesis Three-tiered approach that uses existing data systems, as well as new data collections Integrate/synthesize data from different sources  Health dept-reported program data  Program data obtained from other federal agencies  Population-based, self-report survey data  Population-based, surveillance data

  25. 25. Linking program and surveillance data Important to connect program (process) to outcome to impact Ultimately, need to assess whether programs contribute to outcomes, which contribute to long-term impact in communit y No true, direct link across… however, through triangulation of data and methods, we might achieve convergence
  26. 26. Firsts for CDC First time CDC will:  Connect HIV program data to community-level outcome data to long-term impact  Integrate and synthesize HIV-related information gathered from a variety of existing and new data sources  Triangulate data to make a broad statement about how/whether public health strategies are working in highest prevalence areas
