Antiretroviral-based interventions for HIV-1 prevention, including antiretroviral therapy (ART) to reduce the infectiousness of HIV-1 infected persons and pre-exposure prophylaxis (PrEP) to reduce the susceptibility of HIV-1 uninfected persons, showed high efficacy for HIV-1 protection in randomized clinical trials. We conducted a prospective implementation study to understand the feasibility and effectiveness of these interventions in delivery settings.
Between November 5, 2012, and January 5, 2015, we enrolled and followed 1,013 heterosexual HIV-1-serodiscordant couples in Kenya and Uganda in a prospective implementation study. ART and PrEP were offered through a pragmatic strategy, with ART promoted for all couples and PrEP offered until 6 mo after ART initiation by the HIV-1 infected partner, permitting time to achieve virologic suppression. One thousand thirteen couples were enrolled, 78% of partnerships initiated ART, and 97% used PrEP, during a median follow-up of 0.9 years. Objective measures of adherence to both prevention strategies demonstrated high use (≥85%). Given the low HIV-1 incidence observed in the study, an additional analysis was added to compare observed incidence to incidence estimated under a simulated counterfactual model constructed using data from a prior prospective study of HIV-1-serodiscordant couples. Counterfactual simulations predicted 39.7 HIV-1 infections would be expected in the population at an incidence of 5.2 per 100 person-years (95% CI 3.7-6.9). However, only two incident HIV-1 infections were observed, at an incidence of 0.2 per 100 person-years (95% CI 0.0-0.9, p < 0.0001 versus predicted). The use of a non-concurrent comparison of HIV-1 incidence is a potential limitation of this approach; however, it would not have been ethical to enroll a contemporaneous population not provided access to ART and PrEP.
Integrated delivery of time-limited PrEP until sustained ART use in African HIV-1-serodiscordant couples was feasible, demonstrated high uptake and adherence, and resulted in near elimination of HIV-1 transmission, with an observed HIV incidence of <0.5% per year compared to an expected incidence of >5% per year.

The rollout of antiretroviral therapy in sub-Saharan Africa has brought lifesaving treatment to millions of HIV-infected individuals. Treatment is lifelong, however, and to continue to benefit, patients must remain in care. Despite this, systematic investigations of retention have repeatedly documented high rates of loss to follow-up from HIV treatment programs. This paper introduces an explanation for missed clinic visits and subsequent disengagement among patients enrolled in HIV treatment and care programs in Africa.
Eight-hundred-ninety patients enrolled in HIV treatment programs in Jos, Nigeria; Dar es Salaam, Tanzania; and Mbarara, Uganda who had extended absences from care were tracked for qualitative research interviews. Two-hundred-eighty-seven were located, and 91 took part in the study. Interview data were inductively analyzed to identify reasons for missed visits and to assemble them into a broader explanation of how missed visits may develop into disengagement. Findings reveal unintentional and intentional reasons for missing, along with reluctance to return to care following an absence. Disengagement is interpreted as a process through which missed visits and ensuing reluctance to return over time erode patients' subjective sense of connectedness to care.
Missed visits are inevitable over a lifelong course of HIV care. Efforts to prevent missed clinic visits combined with moves to minimize barriers to re-entry into care are more likely than either approach alone to keep missed visits from turning into long-term disengagement.

Individuals living with HIV/AIDS in sub-Saharan Africa generally take more than 90% of prescribed doses of antiretroviral therapy (ART). This number exceeds the levels of adherence observed in North America and dispels early scale-up concerns that adherence would be inadequate in settings of extreme poverty. This paper offers an explanation and theoretical model of ART adherence success based on the results of an ethnographic study in three sub-Saharan African countries.
Determinants of ART adherence for HIV-infected persons in sub-Saharan Africa were examined with ethnographic research methods. 414 in-person interviews were carried out with 252 persons taking ART, their treatment partners, and health care professionals at HIV treatment sites in Jos, Nigeria; Dar es Salaam, Tanzania; and Mbarara, Uganda. 136 field observations of clinic activities were also conducted. Data were examined using category construction and interpretive approaches to analysis. Findings indicate that individuals taking ART routinely overcome economic obstacles to ART adherence through a number of deliberate strategies aimed at prioritizing adherence: borrowing and \"begging\" transport funds, making \"impossible choices\" to allocate resources in favor of treatment, and \"doing without.\" Prioritization of adherence is accomplished through resources and help made available by treatment partners, other family members and friends, and health care providers. Helpers expect adherence and make their expectations known, creating a responsibility on the part of patients to adhere. Patients adhere to promote good will on the part of helpers, thereby ensuring help will be available when future needs arise.
Adherence success in sub-Saharan Africa can be explained as a means of fulfilling social responsibilities and thus preserving social capital in essential relationships.

Background
People living with HIV are vulnerable to gender-based violence (GBV), which can negatively impact HIV treatment outcomes. National guidelines in Uganda recommend GBV screening alongside HIV treatment services. We explored barriers and facilitators to providers implementing GBV screening and referral in public antiretroviral therapy (ART) clinics in Uganda.
Methods
We conducted qualitative in-depth interviews. Providers were purposively sampled from 12 ART clinics to represent variation in clinical specialty and gender. We used the Theoretical Domains Framework to structure our deductive analysis.
Results
We conducted 30 in-depth interviews with providers implementing GBV screening and/or referral. Respondents had a median age of 36 (IQR: 30, 43) years and had been offering post-GBV care to clients for a median duration of 5 (4, 7) years. 67% of respondents identified as female and 57% were counselors. Facilitators of GBV screening and referral included providers having access to post-GBV standard operating procedures and screening tools, trainings offered by the Ministry of Health, facility-sponsored continuing medical education units and support from colleagues. Respondents indicated that referrals were uncommon, citing the following barriers: negative expectations regarding the quality and quantity of referral services; lack of financial resources to support clients, facilities, and referral partners throughout the referral process; and sociocultural factors that threatened client willingness to pursue post-GBV support services.
Conclusions
Findings from this evaluation support the refinement of GBV screening and referral implementation strategies that leverage facilitators and address barriers to better support individuals living with HIV and who may have heightened vulnerability to GBV.

Introduction HIV self‐testing (HIVST) and oral pre‐exposure prophylaxis (PrEP) are complementary, evidence‐based, self‐controlled HIV prevention tools that may be particularly appealing to sex workers. Understanding how HIVST and PrEP are perceived and used by sex workers and their intimate partners could inform prevention delivery for this population. We conducted qualitative interviews to examine ways in which HIVST and PrEP use influence prevention choices among sex workers in Uganda. Methods Within a randomized trial of HIVST and PrEP among 110 HIV‐negative cisgender women, cisgender men and transgender women sex workers (NCT03426670), we conducted 40 qualitative interviews with 30 sex workers and 10 intimate partners (June 2018 to January 2020). Sex worker interviews explored (a) experiences of using HIVST kits; (b) how HIVST was performed with sexual partners; (c) impact of HIVST on PrEP pill taking; and (d) sexual risk behaviours after HIVST. Partner interviews covered (i) introduction of HIVST; (ii) experiences of using HIVST; (iii) HIV status disclosure; and (iv) HIVST's effect on sexual behaviours. Data were analysed using an inductive content analytic approach centering on descriptive category development. Together, these categories detail the meaning of HIVST and PrEP for these qualitative participants. Results Using HIVST and PrEP was empowering for this group of sex workers and their partners. Three types of empowerment were observed: (a) economic; (b) relational; and (c) sexual health. (i) Using HIVST and PrEP made sex without condoms safer. Sex workers could charge more for condomless sex, which was empowering economically. (ii) Self‐testing restored trust in partners’ fidelity upon being reunited after a separation. This trust, in combination with condomless sex made possible by PrEP use, restored intimacy, empowering partnered relationships. (iii) HIVST and PrEP enabled sex workers to take control of their HIV prevention efforts and avoid the stigma of public clinic visits. In this way they were empowered to protect their sexual health. Conclusions In this sample, sex workers’ use of HIVST and PrEP benefitted not only prevention efforts, but also economic and relational empowerment. Understanding these larger benefits and communicating them to stakeholders could strengthen uptake and use of combination prevention interventions in this marginalized population.

Introduction Peer delivery is a client‐centred approach that could maximize the coverage and impact of HIV services for transgender women (TGW). We conducted qualitative interviews to examine how peer‐delivered HIV self‐testing (HIVST), sexually transmitted infection self‐sampling (STISS) and oral pre‐exposure prophylaxis (PrEP) influenced prevention choices among TGW and their intimate partners in Uganda. Methods Within a cluster randomized trial of peer‐delivered HIVST, STISS and PrEP among HIV‐negative TGW (NCT04328025), we conducted 55 qualitative interviews with 30 TGW, 15 intimate partners and 10 TGW peers (August 2021–February 2022). TGW interviews explored: (1) HIV self‐test and PrEP experiences; (2) HIVST with intimate partners; and (3) descriptions of self‐sampling for STI testing. Partner interviews covered: (1) experiences with HIVST; (2) disclosure of HIV status to intimate partner; and (3) descriptions of sexual behaviours after testing. Peer interview topics included: (1) intervention delivery experiences; and (2) recommendations for peer‐delivered HIV prevention services to TGW, including psychological support and coping strategies. Qualitative data were analysed using an inductive content analytic approach. Results Peer‐delivered combination prevention was valued by this group of TGW and their partners. (1) Peer services extended beyond delivering HIV/STI kits and PrEP refills to caring for individual health and wellbeing by providing stigma coping strategies. Peer psychosocial support empowered research participants to become “HIVST ambassadors,” teach non‐study TGW about self‐testing and PrEP, and encourage linkage to care. (2) HIVST with intimate partners and mutual disclosure of HIV status strengthened partnered relationships. PrEP use after both partners tested HIV negative implied infidelity. (3) Self‐sampling enabled TGW to take control of their STI testing and avoid the embarrassment of exposing their bodies. Privacy and confidentiality motivated the uptake of STI testing and treatment. Conclusions In this sample of TGW from Uganda, peer delivery of HIVST, STISS and PrEP refills benefitted individual prevention efforts and extended to a new linkage of TGW not engaged in care. Integrating peer services into differentiated PrEP delivery could increase HIV/STI test coverage and PrEP use in this vulnerable population.

Introduction Increased HIV testing by men in sub‐Saharan Africa is key to meeting UNAIDS 2025 testing targets. Secondary distribution of HIV self‐testing (HIVST) kits by pregnant women attending antenatal care to male partners has been shown to increase testing among African men. A detailed understanding of how women and male partners manage the distribution and use of HIVST and subsequent linkage to clinic‐based follow‐up can inform implementation and scale‐up efforts. Methods We use qualitative data from the Obumu Study, a randomized trial of secondary distribution of HIVST by pregnant women living with HIV to male partners in Kampala, Uganda, to unpack the HIVST delivery process. The protocol included a clinic visit by male partners to confirm HIVST results. Individual interviews eliciting data on experiences of delivering and using HIVST and of subsequent linkage to clinic‐based testing were conducted with a purposefully selected sample of 45 women and 45 male partner Obumu Study participants from November 2018 to March 2021. Interview data from 59 participants (29 women and 30 men) in the HIVST arm were analysed through coding and category construction. Results Women living with HIV were apprehensive about delivering HIVST to their partners, especially if they had not disclosed their HIV status. They invested effort in developing strategies for introducing HIVST. Male partners described a range of responses to receiving the self‐testing kit, especially fear of a positive test result. Women reported leading the self‐testing process, often conducting the test themselves. Most women confidently interpreted HIVST results. However, they tended to defer to healthcare workers rather than report positive results directly to partners. Women told their partners the testing process required a clinic follow‐up visit, often without explaining the visit's purpose. Many partners delayed the visit as a result. Women again responded by strategizing to persuade their partners to link to follow‐up care. Conclusions Secondary distribution of HIVST by pregnant women living with HIV to male partners can be challenging, especially when women have not disclosed their HIV status. Additional support may alleviate the burden; outreach to male partners may facilitate linkage to confirmatory testing and HIV care or prevention.

Urine tenofovir testing for real‐time PrEP adherence feedback: a qualitative study involving transgender women in Uganda
2024
Introduction Adherence counselling with point‐of‐care (POC) drug‐level feedback using a novel tenofovir assay may support pre‐exposure prophylaxis (PrEP) adherence; however, perceptions of urine testing and its impact on adherence are not well studied. We qualitatively examined how POC tenofovir testing was experienced by transgender women (TGW) in Uganda. Methods Within a cluster randomized trial of peer‐delivered HIV self‐testing, self‐sampling for sexually transmitted infections and PrEP among HIV‐negative TGW showing overall low PrEP prevention‐effective adherence (NCT04328025), we conducted a nested qualitative sub‐study of the urine POC assay among a random sample of 30 TGW (August 2021−February 2022). TGW interviews explored: (1) experiences with POC urine tenofovir testing and (2) perceptions of PrEP adherence counselling with drug‐level feedback. We used an inductive content analytic approach for analysis. Results Median age was 21 years (interquartile range 20–24), and 70% engaged in sex work. Four content categories describe how TGW experienced POC urine tenofovir testing: (1) Urine tenofovir testing was initially met with scepticism: Testing urine to detect PrEP initially induced anxiety, with some perceptions of being intrusive and unwarranted. With counselling, however, participants found POC testing acceptable and beneficial. (2) Alignment of urine test results and adherence behaviours: Drug‐level feedback aligned with what TGW knew about their adherence. Concurrence between pill taking and tenofovir detection in urine reinforced confidence in test accuracy. (3) Interpretation of urine tenofovir results: TGW familiar with the interpretation of oral‐fluid HIV self‐tests knew that two lines on the test device signified positivity (presence of HIV). However, two lines on the urine test strip indicated a positive result for non‐adherence (absence of tenofovir), causing confusion. Research nurses explained the difference in test interpretation to participants’ satisfaction. (4) White coat dosing: Some TGW deliberately chose not to attend scheduled clinic appointments to avoid detecting their PrEP non‐adherence during urine testing. They restarted PrEP before returning to clinic, a behaviour called “white coat dosing.” Conclusions Incorporating POC urine testing into routine PrEP adherence counselling was acceptable and potentially beneficial for TGW but required attention to context. Additional research is needed to identify effective strategies for optimizing adherence monitoring and counselling for this population.

Background: High adherence to antiretroviral therapy (ART) is critical for achieving viral suppression and preventing onward HIV transmission. ART continuation can be challenging for pregnant women living with HIV (PWLHIV), which has critical implications for risk of vertical HIV transmission. Point-of-care viral load (POC VL) testing has been associated with improved treatment and retention outcomes. We sought to explore acceptability of POC VL testing among Ugandan PWLHIV during pregnancy and postpartum. Methods: This multimethod analysis drew on quantitative and qualitative data collected between February and December 2021. Quantitatively, we used an intent-to-treat analysis to assess whether randomization to clinic-based POC VL testing during pregnancy and infant testing at delivery was associated with improved viral suppression (≤50 copies/mL) by 3 months postpartum compared to standard-of-care (SOC) VL testing through a central laboratory, adjusting for factorial randomization for the male partner testing strategy. Additionally, a subset of 22 PWLHIV in the POC VL arm participated in in-depth qualitative interviews. We inductively analyzed transcripts to develop categories representing concepts that characterized women’s perceptions of POC VL testing during pregnancy and at delivery and ways that POC VL testing may have impacted their ART adherence and viral suppression. Key themes around women’s perceptions of POC VL testing were then organized into main categories. Results: Overall, 151 PWLHIV were enrolled into the study, 77 (51%) of whom were randomized to receive POC VL testing during pregnancy and at delivery. Women reported in qualitative interviews that POC VL testing had (1) motivated their ART adherence during pregnancy and postpartum and that they felt this testing method had (2) helped them protect their infants from acquiring HIV and (3) improved their emotional wellbeing. Conclusions: POC VL testing was highly acceptable among Ugandan PWLHIV and was viewed as an important tool that women believed improved their ART adherence, gave them information necessary to protect their infants from vertical HIV acquisition, and improved their emotional wellbeing. These findings support the global scale-up of POC VL testing in settings with high HIV burden, especially for PWLHIV who may be at risk of treatment disruptions or loss to follow-up.

Introduction The successes of HIV treatment scale‐up and the availability of new prevention tools have raised hopes that the epidemic can finally be controlled and ended. Reduction in HIV incidence and control of the epidemic requires high testing rates at population levels, followed by linkage to treatment or prevention. As effective linkage strategies are identified, it becomes important to understand how these strategies work. We use qualitative data from The Linkages Study, a recent community intervention trial of community‐based testing with linkage interventions in sub‐Saharan Africa, to show how lay counsellor home HIV testing and counselling (home HTC) with follow‐up support leads to linkage to clinic‐based HIV treatment and medical male circumcision services. Methods We conducted 99 semi‐structured individual interviews with study participants and three focus groups with 16 lay counsellors in Kabwohe, Sheema District, Uganda. The participant sample included both HIV+ men and women (N=47) and HIV‐uncircumcised men (N=52). Interview and focus group audio‐recordings were translated and transcribed. Each transcript was summarized. The summaries were analyzed inductively to identify emergent themes. Thematic concepts were grouped to develop general constructs and framing propositional statements. Results Trial participants expressed interest in linking to clinic‐based services at testing, but faced obstacles that eroded their initial enthusiasm. Follow‐up support by lay counsellors intervened to restore interest and inspire action. Together, home HTC and follow‐up support improved morale, created a desire to reciprocate, and provided reassurance that services were trustworthy. In different ways, these functions built links to the health service system. They worked to strengthen individuals’ general sense of capability, while making the idea of accessing services more manageable and familiar, thus reducing linkage barriers. Conclusions Home HTC with follow‐up support leads to linkage by building “social bridges,” interpersonal connections established and developed through repeated face‐to‐face contact between counsellors and prospective users of HIV treatment and male circumcision services. Social bridges link communities to the service system, inspiring individuals to overcome obstacles and access care.
