  1. HIV Partner Notification in the U.S.: A National Survey of Program Coverage and Outcomes Matthew Golden MD, MPH Assistant Professor of Medicine, UW Medical Director, PHSKC STD Clinic

  2. Background • New CDC HIV prevention initiatives emphasize HIV partner • notification, or PCRS. • Current data on HIV PCRS are limited & mostly anecdotal • Several health departments reported success in • identifying new cases of HIV in the 1980s & early 1990s • A RCT of 74 people found that provider referral was • more successful than patient referral • Recent, single center studies reported conflicting results • San Francisco – virtually no one accepted PCRS • North Carolina – 11 index patients interviewed to • identify one new case HIV • No national data on PN outcomes

  3. Methods • Survey of health departments in cities reporting >200 cases AIDS in 2001 • Directed to HIV program directors • If local health department indicated states managed PCRS, survey was forwarded to the state • Survey – 2 page instrument • Organization of PCRS • Aggregate PCRS outcomes – number index patients interviewed, number requesting assistance, disposition of partners

  4. Methods • Primary outcomes • Proportion of persons with HIV/AIDS interviewed • Number needed to interview to identify one new case of HIV • NNTI= # interviewed / # new HIV cases identified • Brought to treatment index=1/NNTI

  5. Outcomes: Participation 39 jurisdictions >200 AIDS cases 2001 39 jurisdictions contacted 11 no data 28 (72%) provided data • Participating jurisdictions reported 24,006 cases of AIDS in 2001 • 58% AIDS cases nationally • 69% AIDS cases in metropolitan areas >500,000

  6. Participating Jurisdictions Person completing survey Surveillance supervisor DIS supervisor HIV/AIDS pgrm director Region Northeast Midwest South West Number AIDS cases <500 501-1000 >1000 N (%) 13 (48) 5 (18) 9 (33) 5 (18) 3 (11) 13 (48) 6 (22) 10 (44) 8 (35) 5 (22)

  7. Outcomes: Program Coverage* Aggregate Coverage Median Range 32% 55% 2-100% * Restricted to 22 areas reporting numbers of cases of HIV. Among 20,353 HIV cases reported

  8. Program Coverage of PCRS Percentage of jurisdictions providing routine PCRS services in public & private counseling & testing sites Percentage of jurisdictions that restrict routine PCRS to public health testing sites by number of AIDS cases in area P=.0001 P=.04 _

  9. Percentage of persons with HIV accepting assistance to notify at least one partner* Aggregate Median Range 41% 57% 4-100 * Among 19 jurisdictions providing information

  10. Association of proportion of MSM among AIDS cases & proportion of persons with HIV accepting assistance notifying at least one partner r=-.44 p=.04 % accepting PCRS assistance Proportion AIDS cases in MSM

  11. HIV PCRS Outcomes Among 6,394 Partners of Persons with HIV in 23 U.S. Public Health Jurisdictions Outcome defined 61% partners Percent

  12. Outcomes: NNTI* Aggregate Median Range 13.8 13.4 1-196 * Among 8,349 index cases interviewed in 26 jurisdictions

  13. Association of percentage MSM among AIDS cases & number of persons needs to interview to find a new case of HIV r=.46 p=.02 NNI to find a new case of HIV Percent AIDS cases in MSM

  14. Conclusions • HIV PCRS currently affects a minority of persons diagnosed with HIV in the U.S. – Lowest coverage in areas with the most cases • Process outcomes suggest PCRS is often successful in identifying new cases • Uncertain how many of these persons would have been referred in the absence of a PCRS program • Success is highly variable • Aggregate data suggest efforts are less successful among MSM

  15. Implications • Reasonable case finding yields suggest that HIV PCRS is effective & should be expanded • Nationally, program coverage is low & areas with the largest number of cases have the greatest need to expand • New, probably federal, resources will be needed • PCRS may be less effective in MSM • Data from North Carolina suggests failure is not universal • Future studies should look at individual level data and PCRS success • New models of PCRS may be needed for MSM • The inability of large numbers of health departments to provide basic statistics on their PCRS program coverage & outcomes suggests PCRS supervision and data management need improvement
