Integrated Delivery of Antiretroviral Treatment and Pre-exposure Prophylaxis to HIV-1–Serodiscordant Couples: A Prospective Implementation Study in Kenya and Uganda
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.
Conceptual model for pluralistic healthcare behaviour: results from a qualitative study in southwestern Uganda
IntroductionMedical pluralism, or concurrent utilisation of multiple therapeutic modalities, is common in various international contexts, and has been characterised as a factor contributing to poor health outcomes in low-resource settings. Traditional healers are ubiquitous providers in most regions, including the study site of southwestern Uganda. Where both informal and formal healthcare services are both available, patients do not engage with both options equally. It is not well understood why patients choose to engage with one healthcare modality over the other. The goal of this study was to explain therapeutic itineraries and create a conceptual framework of pluralistic health behaviour.MethodsIn-depth interviews were conducted from September 2017 to February 2018 with patients seeking care at traditional healers (n=30) and at an outpatient medicine clinic (n=30) in Mbarara, Uganda; the study is nested within a longitudinal project examining HIV testing engagement among traditional healer-using communities. Inclusion criteria included age ≥18 years, and ability to provide informed consent. Participants were recruited from practices representing the range of healer specialties. Following an inductive approach, interview transcripts were reviewed and coded to identify conceptual categories explaining healthcare utilisation.ResultsWe identified three broad categories relevant to healthcare utilisation: (1) traditional healers treat patients with ‘care’; (2) biomedicine uses ‘modern’ technologies and (3) peer ‘testimony’ influences healthcare engagement. These categories describe variables at the healthcare provider, healthcare system and peer levels that interrelate to motivate individual engagement in pluralistic health resources.ConclusionsPatients perceive clear advantages and disadvantages to biomedical and traditional care in medically pluralistic settings. We identified factors at the healthcare provider, healthcare system and peer levels which influence patients’ therapeutic itineraries. Our findings provide a basis to improve health outcomes in medically pluralistic settings, and underscore the importance of recognising traditional healers as important stakeholders in community health.
Toward an Understanding of Disengagement from HIV Treatment and Care in Sub-Saharan Africa: A Qualitative Study
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.
Adherence to Antiretroviral Prophylaxis for HIV Prevention: A Substudy Cohort within a Clinical Trial of Serodiscordant Couples in East Africa
Randomized clinical trials of oral antiretroviral pre-exposure prophylaxis (PrEP) for HIV prevention have widely divergent efficacy estimates, ranging from 0% to 75%. These discrepancies are likely due to differences in adherence. To our knowledge, no studies to date have examined the impact of improving adherence through monitoring and/or intervention, which may increase PrEP efficacy, or reported on objective behavioral measures of adherence, which can inform PrEP effectiveness and implementation. Within the Partners PrEP Study (a randomized placebo-controlled trial of oral tenofovir and emtricitabine/tenofovir among HIV-uninfected members of serodiscordant couples in Kenya and Uganda), we collected objective measures of PrEP adherence using unannounced home-based pill counts and electronic pill bottle monitoring. Participants received individual and couples-based adherence counseling at PrEP initiation and throughout the study; counseling was intensified if unannounced pill count adherence fell to <80%. Participants were followed monthly to provide study medication, adherence counseling, and HIV testing. A total of 1,147 HIV-uninfected participants were enrolled: 53% were male, median age was 34 years, and median partnership duration was 8.5 years. Fourteen HIV infections occurred among adherence study participants--all of whom were assigned to placebo (PrEP efficacy = 100%, 95% confidence interval 83.7%-100%, p<0.001). Median adherence was 99.1% (interquartile range [IQR] 96.9%-100%) by unannounced pill counts and 97.2% (90.6%-100%) by electronic monitoring over 807 person-years. Report of no sex or sex with another person besides the study partner, younger age, and heavy alcohol use were associated with <80% adherence; the first 6 months of PrEP use and polygamous marriage were associated with >80% adherence. Study limitations include potential shortcomings of the adherence measures and use of a convenience sample within the substudy cohort. The high PrEP adherence achieved in the setting of active adherence monitoring and counseling support was associated with a high degree of protection from HIV acquisition by the HIV-uninfected partner in heterosexual serodiscordant couples. Low PrEP adherence was associated with sexual behavior, alcohol use, younger age, and length of PrEP use. Please see later in the article for the Editors' Summary.
Explaining Adherence Success in Sub-Saharan Africa: An Ethnographic Study
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.
Transportation Costs Impede Sustained Adherence and Access to HAART in a Clinic Population in Southwestern Uganda: A Qualitative Study
The cost of transportation for monthly clinic visits has been identified as a potential barrier to antiretroviral (ARV) adherence in sub-Saharan Africa and elsewhere, although there is limited data on this issue. We conducted open-ended interviews with 41 individuals living with HIV/AIDS and attending a clinic in Mbarara, Uganda, to understand structural barriers to ARV adherence and clinical care. Almost all respondents cited the need to locate funds for the monthly clinic visit as a constant source of stress and anxiety, and lack of money for transportation was a key factor in cases of missed doses and missed medical appointments. Participants struggled with competing demands between transport costs and other necessities such as food, housing and school fees. Our findings suggest that transportation costs can compromise both ARV adherence and access to care. Interventions that address this barrier will be important to ensure the success of ARV programs in sub-Saharan Africa.
HIV self‐testing and oral pre‐exposure prophylaxis are empowering for sex workers and their intimate partners: a qualitative study in Uganda
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.
“I felt special!”: a qualitative study of peer‐delivered HIV self‐tests, STI self‐sampling kits and PrEP for transgender women in Uganda
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.
How pregnant women living with HIV and their male partners manage men's HIV self‐testing: qualitative analysis of an HIVST secondary distribution process in Kampala, Uganda
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
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.
