HIV Care Continuum New Diagnoses, 2011, Fulton County, Georgia
Persons with HIV Engaged in Selected Stages of the Continuum of Care, United States 82 66 Percent 37 33 25 Hall et al. XIX International AIDS Conference, 2012 ART, antiretroviral therapy
Care Continuum Methodology, New HIV Diagnoses 2011, Fulton County • Adults and adolescents are those aged >= 13 years • Diagnosed between 01/01/11-12/31/11 • Alive at least 15 months after diagnosis • Residence of diagnosis Fulton County, current address Georgia • Excludes 10 persons deceased within 15 months of diagnosis • Linked to care = CD4 or VL within 3 months of diagnosis, excluding day of diagnosis • Engaged in care >= 1 CD4 or VL 4-15 months after diagnosis • Retained in care >= 2 CD4 or VL at least 3 months apart 4-15 months after diagnosis • Estimated percentage prescribed ART derived from the Medical Monitoring Project (MMP) Georgia sample • Viral suppression (VS) = VL<200 copies/ml in most recent viral load • All percentages are percent of total number of persons diagnosed with HIV
HIV Care Continuum Methodology Months 4-15 after diagnosis Months 0-3 after diagnosis HIV Confirmatory Diagnosis Date CD4 or Viral Load CD4 or Viral Load CD4 or Viral Load Last viral load <200 copies/ml • This person is: • Linked YES • Engaged YES • Retained YES • Virally suppressed YES
HIV Care Continuum Methodology Months 4-15 after diagnosis Months 0-3 after diagnosis HIV Confirmatory Diagnosis Date CD4 or Viral Load CD4 or Viral Load Last viral load undetectable • This person is • Linked YES • Engaged YES • Retained NO • Virally suppressed YES • “Engaged in care” is minimal engagement that indicates the person “touched” the medical system at least once during that 12 month period
HIV Care Continuum Methodology Months 4-15 after diagnosis Months 0-3 after diagnosis HIV Confirmatory Diagnosis Date CD4 or Viral Load CD4 done but no viral load done • This person is • Linked NO • Engaged YES • Retained YES • Virally suppressed NO • If no viral load done, it is assumed to be not suppressed

The HIV Care Continuum can help us… • Focus our efforts for linkage, retention and viral suppression. • Identify groups at increased risk for dropping out of each step in the continuum. • Monitor our progress in improvement of linkage, retention, and viral suppression. • Identify disparities not only in prevalence but in care • Evaluate efforts addressing specific populations with low viral suppression. • Monitor efforts in improving viral suppression in specific counties, census tracts, zip codes and some specific facilities • Encourage improvement in surveillance data completeness (race, sex, transmission category)
Stage of HIV disease at diagnosis • Stage at diagnosis is defined by the first CD4 done within 3 months of diagnosis Stage 1 = CD4 >=500 Stage 2 = CD4 200-499 Stage 3 = CD4 <200 or OI • Stage at diagnosis is unknown if no CD4 done within 3 months of diagnosis

Limitations • Incomplete reporting • Missing data for race/ethnicity, sex, and complete address at diagnosis • Lack of transmission category information • Definition of heterosexual transmission (sexual contact with a known HIV infected partner or person with increased risk, i.e., MSM or IDU) • Missing laboratory reports • CD4 within 3 and 12 months of diagnosis yields high unknown stage in Fulton County and Georgia overall
Uncertainties • Populations for which data are missing may be fundamentally different • How to obtain data for transgender category • How to improve completeness of reporting • Data on ART use • Understanding barriers to ART adherence • Prioritizing further research
