Current antiretroviral therapy (ART) adherence monitoring is premised on patients' self-reported adherence behaviour (prone to recall error) and verified by blood viral load measurement (which can delay results). A newly developed Urine Tenofovir Rapid Assay (UTRA) assesses tenofovir in urine at point-of-care and is a novel tool to test and immediately respond to adherence levels of people living with HIV (PLHIV). We explored PLHIV and health workers' initial perceptions about integrating the UTRA into routine medical care for adherence support. We conducted a series of once-off in-depth qualitative interviews with PLHIV (n = 25) and health workers (n = 5) at a primary care health facility in Cape Town, South Africa. Data analysis involved descriptive summaries of key emergent themes with illustrative case examples. We applied a deductive, outcomes-driven analytic approach to the summaries using the Implementation Outcomes Framework proffered by Proctor et al. (2011). The three relevant concepts from this framework that guided our evaluation were: acceptability, appropriateness, and feasibility. We found positive perceptions about the UTRA from many PLHIV and health worker participants. Many PLHIV reported that the immediate results offered by the UTRA could enable them to have constructive discussions with health workers on how to resolve adherence challenges in real-time. Few PLHIV reported concerns that drinking alcohol could affect their UTRA results. Many health workers reported that the UTRA could help them identify patients at risk of treatment failure and immediately intervene through counselling, though some relayed that they would support the UTRA's implementation if more staff members could be added in their busy facility. Overall, these findings show that the UTRA was widely perceived to be acceptable and actionable by many PLHIV and health workers in the study. [ABSTRACT FROM AUTHOR]

Background: HIV treatment-based prevention modalities present new opportunities for women to make decisions around sex, intimacy, and prevention. The Universal test and treat (UTT) strategy, where widespread HIV testing is implemented and all people with HIV can access treatment, has the potential to change how sex is understood and HIV prevention incorporated into sexual relationships. We use the frame of sexual scripting to explore how women attribute meaning to sex relative to UTT in an HIV prevention trial setting. Exploring women's sexual narratives, we explored how HIV prevention feature in the sexual scripts for women who had access to UTT in South Africa (prior to treatment guideline changes) and increased HIV prevention messaging, compared to places without widespread access to HIV testing and immediate access to treatment.Methods: We employed a two-phased thematic analysis to explore longitudinal qualitative data collected from 71 women (18-35 years old) between 2016 and 2018 as part of an HIV prevention trial in the Western Cape Province, South Africa. Of the participants, 58/71 (82%) were from intervention communities while 13/71 (18%) lived in control communities without access to UTT. Twenty participants self-disclosed that they were living with HIV.Results: We found no narrative differences between women who had access to UTT and those who did not. HIV and HIV prevention, including treatment-based prevention modalities, were largely absent from women's thinking about sex. In their scripts, women idealised romantic sex, positioned sex as 'about relationships', and described risky sex as 'other'. When women were confronted by HIV risk (for example, when a partner disclosed his HIV-positive status) this created a point of disjuncture between this new perception of risk and their accepted relationship scripts.Conclusion: These findings suggest that HIV-negative women did not include their partners' use of antiretroviral therapy in their sexual partnership choices. For these women, the preventive benefits of UTT are experienced passively-through community-wide viral suppression-rather than through their own behaviour change explicitly related to the availability of treatment as prevention. We propose that prevention-based modalities should be made available and supported and framed as an intervention to promote relationship well-being. [ABSTRACT FROM AUTHOR]- Published

The global expansion of HIV testing, prevention and treatment services is necessary to achieve HIV epidemic control and promote individual and population health benefits for people living with HIV (PLHIV) in sub-Saharan Africa. Community-based health workers (CHWs) could play a key role in supporting implementation at scale. In the HPTN 071 (PopART) trial in Zambia and South Africa, a cadre of 737 study-specific CHWs, working closely with government-employed CHW, were deployed to deliver a 'universal' door-to-door HIV prevention package, including an annual offer of HIV testing and referral services for all households in 14 study communities. We conducted a process evaluation using qualitative and quantitative data collected during the trial (2013-2018) to document the implementation of the CHW intervention in practice. We focused on the recruitment, retention, training and support of CHWs, as they delivered study-specific services. We then used these descriptions to: (i) analyse the fidelity to design of the delivery of the intervention package, and (ii) suggest key insights for the transferability of the intervention to other settings. The data included baseline quantitative data collected with the study-specific CHWs (2014-2018); and qualitative data from key informant interviews with study management (n = 91), observations of CHW training events (n = 12) and annual observations of and group discussions (GD) with intervention staff (n = 68). We show that it was feasible for newly recruited CHWs to implement the PopART intervention with good fidelity, supporting the interpretation of the trial outcome findings. This was despite some challenges in managing service quality and CHW retention in the early years of the programme. We suggest that by prioritizing the adoption of key elements of the in-home HIV services delivery intervention model-including training, emotional support to workers, monitoring and appropriate remuneration for CHWs-these services could be successfully transferred to new settings.

In contexts of scarcity, managing comorbidities is a complex process, shaped by divergent understandings of causes, prognoses, and social meanings of illness. Drawing on research with one young South African woman living with HIV and epilepsy, and 13 other people with comorbidities, we describe how concepts of "public" and "private" shape the management of co-morbid conditions. Despite narratives of HIV "normalization," participants labored to keep their HIV status private, while sharing other illness experiences more publicly. We challenge simple dichotomies between public and private spheres and emphasize the need for more fluid understandings of how people negotiate social space. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Public health programming often frames HIV status disclosure as a means to negotiate condom- and abstinence-based prevention or to involve intimate partners in HIV care to garner treatment adherence support. HIV treatment can be used to ensure viral suppression and prevent onward transmission, which provides strong evidence to encourage disclosure. The ideological shift towards HIV treatment as prevention is expected to facilitate disclosure. Purpose: There is a lack of research on how the scale-up of universal HIV testing and treatment influences disclosure practices in high burden settings. In this manuscript, we aim to address this gap. Methods: To this end, we conducted a two-phased narrative performative analysis of the disclosure scripts of 15 women living with HIV in three communities of Western Cape, South Africa where the HPTN 071 (PopART) HIV prevention trial implemented a universal HIV testing and treatment model as part of the intervention. The women were part of a larger cohort nested in the trial. We use Goffman's dramaturgical metaphor, which understands social interactions as 'performances' by 'actors' (people) guided by 'scripts' (anticipated dialogues/interactions), to explore how women living with HIV manage their status disclosure. Conclusion: We describe how these women perform HIV status disclosure (or deliberate non-disclosure) to retain, reaffirm or redefine existing social scripts with partners. Their performances reveal priorities other than those imagined by public health programmes driving HIV disclosure (or non-disclosure): establishing trust, resenting betrayal and ensuring self-preservation while simultaneously (re)constructing self-identity. None of the women engaged with the concept of treatment as prevention in their disclosure narratives, either to facilitate disclosure or to 'justify' non-disclosure. HIV prevention, in general, and treatment adherence support were rarely mentioned as a reason for disclosure. To date, there has been a missed opportunity to ease and support disclosure in health programmes by tapping into existing social scripts, impeding potential patient and public health benefits of universal HIV testing and treatment.

- Abstract
HIV prevalence and incidence in South Africa remain high, making HIV a part of everyday life. Community narratives on HIV treatment and prevention are important and influence official and unofficial health messaging and community perceptions and understandings of HIV. We explore how contributors and the columnist of an agony aunt column position HIV relative to choices made about love, partnership, and sex over three years. We analysed all columns of an agony aunt series (Antie Mona) published between December 2012 and November 2015. The column is published in a South African, Afrikaans-language newspaper “Son”, prioritising sensationalist news items. Trends were identified through narrative analysis. Data were managed in ATLAS.ti and inductive, iterative coding conducted. It was found that letters to the agony aunt rarely refer to HIV directly (less than 7%). Euphemisms such as diseases of the flesh and the great flu were more commonly used instead of HIV or AIDS. Letters addressed HIV in three ways: direct references to experiences living with HIV; direct questions about HIV prevention; and scenarios where HIV could (from a public health perspective) have been the main concern, but everyday issues took precedence. The majority of letters fell into this latter category where the writers focused on the immediate concerns of good sexual relations, problems related to love and romantic relationships, good moral behaviour of others, and issues of oppressive life conditions rather than on HIV directly. The findings illustrate that informal, public contributions to health information, such as agony aunts, are important narratives that inform popular perspectives on HIV and health. A better appreciation of this context would allow health implementers to ensure that these role players receive updated health messaging to avoid the risk of HIV-related stigma where HIV is used as a moral rod to punish perceived moral transgressions.
