Background: The HPTN 071 (PopART) trial implemented universal test and treat (UTT) in three clinics in the Western Cape, South Africa at a time when antiretroviral treatment (ART) was only offered by CD4 threshold and World Health Organization clinical staging. This required a concomitant shift in the way health workers communicated ART initiation messages. We provide insight into front-line ART initiation communication pre-national policy shift. Method: The design of this study was exploratory with a case descriptive analysis of ART initiation in three clinics. To characterise their demographic profiles, we reviewed 134 randomly selected patient clinical folders of people who initiated ART at CD4 counts greater than the recommended standard. Further, we conducted 12 key informant interviews with health workers at these facilities and thematically analysed health workers' responses. Results: The median age of patients initiating ART regardless of CD4 count (above the threshold level) was 33 years and most were women (73.9%), married (76.1%), and unemployed (48.5%). The median CD4 count of patients initiating outside guidelines was 566.5 cells/µl. Contrary to expectations, key informants indicated no radical shift in messaging to explain ART initiation regardless of CD4 count. Rather, they encouraged people living with HIV (PLHIV) to initiate ART while they still "feel well". The reduced risk of onward HIV transmission did not factor significantly in how health workers motivated clients. Conclusion: Motivating PLHIV to initiate ART regardless of CD4 count in high burden settings is possible. However, there are still opportunities to improve messaging about immediate ART initiation or at high CD4 counts for the prevention of onward transmission. [ABSTRACT FROM AUTHOR]

Introduction: HPTN 071 (PopART) is a three-arm community randomized trial in Zambia and South Africa evaluating the impact of a combination HIV prevention package, including universal test and treat (UTT), on HIV incidence. This nested study examined factors associated with timely linkage-to-care and ART initiation (TLA) (i.e. within six-months of referral) in the context of UTT within the intervention communities of the HPTN 071 (PopART) trial. Methods: Of the 7572 individuals identified as persons living with HIV (PLWH) (and not on antiretroviral treatment (ART)) during the first year of the PopART intervention provided by Community HIV-care Providers (CHiPs) through door-to-door household visits, individuals who achieved TLA (controls) and those who did not (cases), stratified by gender and community, were randomly selected to be re-contacted for interview. Standardized questionnaires were administered to explore factors potentially associated with TLA, including demographic and behavioural characteristics, and participants' opinions on HIV and related services. Odds ratios comparing cases and controls were estimated using a multi-variable logistic regression. Results: Data from 705 participants (333 cases/372 controls) were analysed. There were negligible differences between cases and controls by demographic characteristics including age, marital or socio-economic position. Prior familiarity with the CHiPs encouraged TLA (aOR of being a case: 0.58, 95% CI: 0.39 to 0.86, p = 0.006). Participants who found clinics overcrowded (aOR: 1.51, 95% CI: 1.08 to 2.12, p = 0.006) or opening hours inconvenient (aOR: 1.63, 95% CI: 1.06 to 2.51, p = 0.02) were less likely to achieve TLA, as were those expressing stronger feelings of shame about having HIV (ptrend = 0.007). Expressing "not feeling ready" (aOR: 2.75, 95% CI: 1.89 to 4.01, p < 0.001) and preferring to wait until they felt sick (aOR: 2.00, 95% CI: 1.27 to 3.14, p = 0.02) were similarly indicative of being a case. Worrying about being seen in the clinic or about how staff treated patients was not associated with TLA. While the association was not strong, we found that the greater the number of self-reported lifetime sexual partners the more likely participants were to achieve TLA (ptrend = 0.06). There was some evidence that participants with HIV-positive partners on ART were less likely to be cases (aOR: 0.75, 95% CI: 0.53 to 1.06, p = 0.07). Discussion: The lack of socio-demographic differences between cases and controls is encouraging for a "universal" intervention that seeks to ensure high coverage across whole communities. Making clinics more "patient-friendly" could enhance treatment uptake further. The finding that those with higher risk behaviour are more actively engaging with UTT holds promise for treatment-as-prevention. [ABSTRACT FROM AUTHOR]
