2. NIR NIR – Cases with no identified risk represent:
Persons who do not wish to reveal their risk for HIV
Persons who truly do not know how they became infected
Persons for whom risk could not be assessed
Persons for whom risk was not reported
3. Why Collect Risk Information? To monitor changing patterns of transmission;
To effectively counsel the client regarding the spread of HIV;
Community Planning: To assist in targeting resources for populations at increased risk;
To detect any unusual transmission.
4. The NIR Problem The proportion of AIDS & HIV cases reported without risk continues to increase due to:
Increased volume following revised AIDS case definition in 1993
Decreases in surveillance staff to conduct investigations
Increases in heterosexual transmission of HIV to persons without known risk factors
Cases noting sex with the opposite sex, but lacking a risk on the partner(s) will remain as NIR.
5. Acronyms MSM – Men who have sex with men (includes homosexual and bisexual).
IDU – Injecting drug user. This category assumes that needle-sharing has taken place.
Hetero – Persons known to be infected by a partner of the opposite sex and/or that partner has a known HIV/AIDS risk.
NIR – No identified risk. Information regarding risk for HIV was unknown, not determined or denied. This information is updated when determined.
6. Percent of Adult AIDS and HIV Cases Reported with No Identified Risk (NIR) by Sex, U.S. and Florida, 2001
11. Demographics of NIRs in Florida By Sex:
Females have a higher NIR rate than males
By Race/Ethnicity:
Blacks have a higher NIR rate than white or Hispanic cases
By Age:
Persons 60+ have the highest NIR rate
19. In Summary HIV – NIRS
1,058 have been re-classified (10% of total)
52% were adult males
Of these:
49% were reclassed as MSM
13% as IDU
38% as heterosexual
48% were adult females
Of these:
11% were reclassed as IDU
89% as heterosexual
20. HIV – NIRs (continued)
By source of report, the majority of risks were found from:
14% private MDs
12% medical record
43% STD
One-fourth of these risks were identified within 3 months
HIV NIRs dropped from 43% to 39% during this six month period ending on July 1, 2002
In Summary (cont’d)
21. AIDS – NIRs
1,063 AIDS NIRs have been re-classified (7% of total)
65% were adult males of which
49% reclassed as MSM
13% as IDU
38% as heterosexual
35% were adult females
11% reclassed as IDU
89% as heterosexual In Summary (cont’d)
22. AIDS – NIRs (continued)
By source of report, the majority of these risks were found:
21% private MDs
27% medical record reviews
17% STD
One-fourth of these risks were identified within 3 months of report
AIDS NIRs dropped from 19% to 18% during the six month period ending July 1, 2002. In Summary (cont’d)
23. Florida Initiatives to Reduce NIRs Routine database matches with ADAP, STD, TB, etc.
Place educational articles relating to NIR issues in publications that reach out to numerous providers (AETC, Dept. of Corrections, etc.)
Educate private providers at every opportunity on how to identify and report risks, especially for partners of heterosexual cases.
Remind providers that they can notify surveillance of risk information at any time, even if they did not initially report the case.
Dear Colleague letter to providers
24. National Strategies for Dealing with Increased Numbers of NIR Cases Redistribution fraction applied to AIDS cases based on historical patterns of NIR re-classification
Estimating HIV case risks based on patterns of risk redistribution using SHAS data
25. Expanded HIV Risk Assessment Project (EHRAP) – Captures HIV risk information on a sample of persons with HIV/AIDS
Sampling by State health departments for cases reported within a particular period of time. NIR protocol used to validate or identify risk. Sample estimates used to describe distribution in all cases. National Strategies for Dealing with Increased Numbers of NIR Cases (cont’d)
26. How can Providers Help to Reduce NIRs? Explain to your client that in the vast majority of AIDS cases, HIV was acquired through identified transmission routes.
Review the different risk exposures with your client, including the need for details on heterosexual transmission.
27. More Ways That Providers Can Help to Reduce NIRs If you identify a risk on a HIV/AIDS client, notify your local HIV/AIDS surveillance staff, no matter how long ago you reported the case, or even if you were not the provider who initially reported the case.
If a new or unusual transmission route is suspected, notify your local HIV/AIDS surveillance contact as soon as possible.
