Key points for synergy • Understanding how “Key Populations” may mean different things in different contexts • “Key” - refers to specific or heightened vulnerabilities and 'risks' in terms of HIV • Ultimately need to create programs and interventions that address this risk/vulnerability through addressing individual / social / structural factors #AIDS 2016 | @AIDS_conference
Goals for this Presentation • Gaps and losses in care throughout the pre-ART and early-ART phases of the continuum in South Africa • Defining this key population: Individuals presenting for testing who do not initiate ART – What is Treatment Refusal • Data from our recent cohort analyses: Defining key populations and discussing risk factors • Where to go from here: The Treatment Ambassador Program #AIDS 2016 | @AIDS_conference

Risks Perceived in Starting Treatment Losing health or beauty “They said, ‘You are HIV positive, ’ and I said, ‘I am not HIV positive. ’ [. . . ] I told myself that I am beautiful and they say I am HIV positive. Are they sick? I said, no, they are mad. How can they say that? I am very healthy. ” − Female, Sustained Refuser #AIDS 2016 | @AIDS_conference
Risks Perceived in Starting Treatment Stigma associated with disclosure “In a rural area, it’s a small place even though you trust the nurses and stuff like that. People who are in the clinic, they know that you go to that door when you are HIV positive. You come in this way, so they will notice, ‘Wow, she is HIV positive. ’ So they will start talking. ” #AIDS 2016 | @AIDS_conference − Female, Initial Refuser
Risks Perceived in Starting Treatment Increased Financial Burdens “My problem is that sometimes I do not have food to eat at all. How can I take [ARVs] when I don’t have food to eat? So now that means that I will default, but if I knew that I had money then I would take them. ” − Female, False Acceptor #AIDS 2016 | @AIDS_conference
Protective Factors Offsetting Risks of Starting Treatment Coping, Resilience and the importance of Social Support “In rural areas, we have fields where there is no one. I went there and wrote a suicidal letter. It was addressed to my grandmother and aunts. But then I thought of people who love me. I thought my teacher wouldn't’t like this. She wouldn't’t be proud of me, because she knows that I am a fighter. I am a hardworker, and if I do this she will be disappointed. I just cried and then said, let me just pull myself together. I lost my mother. I got shot and survived. So why am I not going to survive this HIV thing? ” #AIDS 2016 | @AIDS_conference − Female, Initial Refuser
COHORT ANALYSIS #AIDS 2016 | @AIDS_conference
Prospective Cohort Study • Determine rates of ART refusal among PLWH at the point of eligibility and over a 6 month period • Assessed modifiable socio-behavioral factors associated with treatment refusal and viral load suppression #AIDS 2016 | @AIDS_conference
Study Sites: Soweto and Gugulethu #AIDS 2016 | @AIDS_conference
Participant Eligibility • Recruitment – 500 ART-eligible participants between July 2014 and June 2015 – ART eligibility changed during study • Pre-Jan 2015: CD 4 ≤ 350 cells/mm 3 • Jan 2015: CD 4 ≤ 500 cells/mm 3 • Pregnant women and children excluded #AIDS 2016 | @AIDS_conference
The Theory of Triadic Influence: Informing Measure Selection Domain Individual Factors Measure • Self-assessed health • Self-efficacy • Coping skills • Fatalism • Denial Social Factors • Social support • Social norms • Perceived stigma Structural Factors • Access to care • Perceived quality of care • Food insecurity #AIDS 2016 | @AIDS_conference Outcome Primary: Rates of ART Refusal at baseline, 3 months and 6 months Secondary: • Factors associated with ART refusal • HIV-1 RNA suppression at six months
Study Recruitment 1071 adults presented for VCT and eligible for ART 360 (34%) lost after testing [Median CD 4: 194] [IQR: 160– 355] 711 (66%) presented for CD 4 results [Median CD 4: 262] [IQR: 141– 372] 500 enrolled in study #AIDS 2016 | @AIDS_conference
Baseline Characteristics Variable Total (n=500) Median Age 35 years Female 63 % Median CD 4 + 244 cells/mm 3 Unemployed 57% Repeat testers 62% Repeat testers with a prior positive test #AIDS 2016 | @AIDS_conference 60%
Baseline (point of testing) • 6. 6% of ART-eligible individuals who presented for testing reported they were not planning to start treatment. • Significantly higher odds of fatalistic beliefs #AIDS 2016 | @AIDS_conference

Treatment Refusal • At 6 months: – 1. 8% (n=9) died within 6 months – 44. 4% (n=222) had yet to initiate • Verified through the National Health Laboratory Service or clinic records • Perceptions of low ART efficacy was significantly associated with sustained refusal #AIDS 2016 | @AIDS_conference
Viral Load Suppression • Ultimately, only 25% of our cohort (125 participants) were virally suppressed within nine months of learning eligibility. • Participants who refused ART at 6 months were significantly more likely to be unable to suppress their viral load at 9 months (p<0. 001) • #AIDS 2016 | @AIDS_conference
Long-term outcome • Low rates of viral load suppression among this high-risk key population • Treatment refusal is significantly associated with a lack of viral load suppression #AIDS 2016 | @AIDS_conference
