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
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
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
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
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

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
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
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
