Outline Outcome measures of the National HIV/AIDS Strategy Surveillance data collection Preliminary data Conclusion
National HIV/AIDS Strategy Reducing New HIV Infections Increasing Access to Care and Improving Health Outcomes for People Living with HIV Reducing HIV-Related Health Disparities
Reducing New HIV Infections Lower the annual number of new infections by 25 percent Reduce the HIV transmission rate, which is a measure of annual transmissions in relation to the number of people living with HIV, by 30 percent Increase from 79 percent to 90 percent the percentage of people living with HIV who know their serostatus
Increasing Access to Care and Improving Health Increase the proportion of newly diagnosed patients linked to clinical care within three months of their HIV diagnosis from 65 percent to 85 percent Increase the proportion of Ryan White HIV/AIDS Program clients who are in continuous care (at least 2 visits for routine HIV medical care in 12 months at least 3 months apart) from 73 percent to 80 percent A benchmark for surveillance?
Reducing HIV-Related Health Disparities Increase the proportion of HIV diagnosed gay and bisexual men with undetectable viral load by 20 percent Increase the proportion of HIV diagnosed Blacks with undetectable viral load by 20 percent Increase the proportion of HIV diagnosed Latinos with undetectable viral load by 20 percent

National HIV/AIDS Strategy Implementation Plan VA, CMS, HRSA, CDC, SAMHSA and NIH will jointly consider and issue a report of strategies to encourage providers to collect and report standardized viral load and CD4 data from infected individuals within populations at greatest risk for HIV infection. CDC will identify which States and localities collect CD4 and viral load data HRSA and CDC will convene a consultation with clinical providers and community-based organizations to develop recommendations for gathering and reporting necessary data to calculate community viral load CDC, in consultation with States, will provide technical assistance to localities, particularly those with a heavy disease burden, to collect necessary data to calculate community viral load
National HIV/AIDS Strategy Implementation Plan CDC will release a report on suggestions for border states to help improve HIV surveillance and prevention interventions among migrant communities CDC will provide State health departments with greater concentrations of AAPI or AI/AN populations with recommendations on effective HIV surveillance activities for these small populations HHS OS will coordinate among HHS agencies to mine existing databases to explore associations between HIV infection and social determinants of health

Conclusion Of 9 outcome measures in the National HIV/AIDS Strategy, 8 can be measured with surveillance data However, there is a need to Support and strengthen HIV … surveillance activities: There is a need to support existing surveillance methods to identify populations at greatest risk that need to be targeted for HIV prevention services.
