  1. Monitoring Indicators of the National HIV/AIDS StrategyUsing Data for Public Health Action Irene Hall, PhD, FACE HIV Incidence and Case Surveillance Branch 2012 CSTE Annual Conference HIV Surveillance Pre-conference Workshop Omaha, NE June 3, 2012 National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention Division of HIV/AIDS Prevention

  2. National HIV/AIDS Strategy (NHAS)Indicator Program • CDC developed a SAS program to assist local and state HIV surveillance programs to assess: • Linkage to care within 3, 6, and 12 months following HIV infection diagnosis, and • Retention in care and viral load suppression among persons living with diagnosed HIV infection • The fully automated SAS program was made available on HICSB’s SiteScape (now SharePoint) on January 12, 2012

  3. NHAS Indicator Program - Definitions • Linkage to care: • There is at least one result of a CD4 or viral load test based on a specimen collected within the specified time period following diagnosis • Retention in HIV care • Had at least two CD4 and/or viral load tests (two care visits) at least three months apart during the specified year • Viral suppression • The most recent viral load measured during the specified year was less than or equal (≤) 200 copies per milliliter

  4. NHAS Indicator Program – Reporting Delays • Recommendation: • Linkage to care: allow at least 3 months delay for reporting and data entry of laboratory test results (after observation period) • Retention in care and viral suppression: allow at least 18 months delay in death reporting • Table footnotes will indicate if insufficient length of time has been given to account for reporting delays

  5. NHAS Indicator Program – Case Inclusion Criteria • Meet the surveillance case definition of HIV infection • Resided in the area when diagnosed with HIV • Person View status is ‘A – Active’, ‘R – Required field missing’, or ‘W – Warning’ • Linkage to care: • Year and month of HIV diagnosis are known • At least 13 years old at the time of diagnosis • Irrespective of vital status after diagnosis • Retention in care and viral suppression: • Year of HIV diagnosis is known • At least 13 years old at the end of the specified time period • Presumed alive at the end of the specified time period

  6. NHAS Indicator Program – Test Inclusion Criteria • CD4 (count or percent) • HIV viral load • Linkage to care: specimen collected in or after the month of HIV diagnosis • Viral suppression: result or result interpretation is not blank

  11. National HIV/AIDS Strategy (NHAS)Line-listing Program • CDC is developing a SAS program to assist local and state HIV surveillance programs to list persons: • Not linked to care within 3, 6, and 12 months following HIV infection diagnosis (no CD4 or VL test within time period) • Not in care during specified time period (no CD4 or VL test in time period) • The SAS program is currently being revised after preliminary testing • Output to list facility of latest document

  12. Line-listing Program • Specifications • Case inclusion criteria: see NHAS program • HIV infected people who are alive at the time of the data run • 2 sets of outputs: (1) no cd4/VL and (2) no lab within the time period • Reporting delays: see NHAS program • Note: laws/regulations, completeness of lab reporting, and data entry will affect results

  13. Line Listing Variables • Care: No CD4/VL, No lab • Diagnosis: date, status, PV status • ID: STATENO, eHARS unique identifier, Document ID • Personal identifiers: name, address at dx, current • RIDR duplicate status • Vital status

  14. Line-listing Program: Output—Not in Care Facility information from most recent lab report available; or, if no lab report available, facility of diagnosis.
