Abstract
BACKGROUND Low-cost, scalable strategies are necessary to reach the UNAIDS 2030 target of ending HIV as a public health threat. Use of treatment partners, informal caregivers selected by people living with HIV to support antiretroviral therapy adherence, is one such strategy that is included in many countries' HIV guidelines, including Botswana, a country with high HIV prevalence. METHOD From June 2021 to June 2022, we pilot tested a clinic-based treatment partner intervention ("Mopati"), including standardized language for providers to guide patients on treatment partner selection and workshops to train treatment partners on providing non-directive support to patients using a non-confrontational, non-judgmental approach. Sixty unsuppressed patients (30 per clinic) and 45 treatment partners (17 intervention, 28 control) were recruited from an intervention-control clinic matched-pair in Gaborone, Botswana. RESULTS Mopati had medium-to-large effects on increasing patients' adherence, adherence self-efficacy, intrinsic adherence motivation, and perceived non-directive support from treatment partners, and decreasing treatment partner caregiver burden. Aggregate viral suppression rates significantly increased in the intervention (vs. control) clinic. Qualitative data from 14 clinic staff, 21 patients, and 16 treatment partners indicated that Mopati was viewed as effective. Providers said the guidance empowered them to be proactive in communicating about adherence; most reported using the guidance. CONCLUSION This study shows preliminary support for the use of treatment partners in HIV care, and further evidence for interventions that leverage patients' existing support. This research can inform ways to improve adherence to HIV treatment as well as the treatment of HIV-related comorbid conditions in lower-resource settings. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT04796610.

Co-Designing Digital Health Intervention for Monitoring Medication and Consultation Among Transgender People in Underserved Communities: Collaborative Approach. JMIR Hum Factors 2024; 11:e45826. [PMID: 39264700 PMCID: PMC11444122 DOI: 10.2196/45826] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2023] [Revised: 06/30/2023] [Accepted: 07/11/2024] [Indexed: 09/13/2024] Open
Abstract
BACKGROUND In many parts of the world, men who have sex with men and transgender individuals face criminalization and discrimination. As a result, they are less likely to seek medical help, despite experiencing higher rates of HIV/AIDS, mental health issues, and other health problems. Reaching key populations (KPs) with essential testing, care, and treatment services can be challenging, as they often have a higher likelihood of contracting and spreading the virus. They have limited access to antiretroviral (ARV) therapy (ART) services, which means that KPs may continue to serve as reservoirs for new HIV infections if they do not receive effective HIV programming. This ongoing issue complicates efforts to control the epidemic. Therefore, modeling a digital health system to track ARV medication access and use is crucial. This paper advocates for the use of digital interventions to manage the health of KPs in underserved regions, using Nigeria as a case study. OBJECTIVE This study aims to assess digital health interventions for monitoring medication and consultations among transgender people in underserved communities. It also sought to determine whether a system exists that could support ART adherence in Nigeria. Additionally, the study evaluated design strategies to address privacy and confidentiality concerns, aiming to reduce nonadherence to ARV medications among KPs in Nigeria. METHODS A qualitative approach was adopted for this research, involving a thematic analysis of information collected from interviews with clinicians and other health practitioners who work directly with these communities, as well as from an interactive (virtual) workshop. RESULTS The findings from the thematic analysis indicate a need to increase attendance at ART therapy sessions through the implementation of an intensive care web app. Unlike previous solutions, this study highlights the importance of incorporating a reminder feature that integrates with an in-app telemedicine consultancy platform. This platform would facilitate discussions about client challenges, such as adverse drug effects, counseling sessions with clinical psychologists, and the impact of identity discrimination on mental health. Other data-driven health needs identified in the study are unique drug request nodes, client-led viral load calculators, remote requests, and drug delivery features within the web app. Participants also emphasized the importance of monitoring medication compliance and incorporating user feedback mechanisms, such as ratings and encouragement symbols (eg, stars, checkmarks), to motivate adherence. CONCLUSIONS The study concludes that technology-driven solutions could enhance ART adherence and reduce HIV transmission among transgender people. It also recommends that local governments and international organizations collaborate and invest in health management services that prioritize health needs over identity.

Abstract
Children who are HIV-exposed and uninfected (CHEU) are at increased risk for poor growth, health, and development compared to children who are HIV-unexposed and uninfected. To support families with CHEU, we assessed the acceptability of engaging family members to support women living with HIV (WLWH) with exclusive breastfeeding (EBF) and antiretroviral therapy (ART) adherence and to engage in responsive infant caregiving. We conducted trials of improved practices, a consultative research approach, that follows participants over time as they try recommended behaviors. We enrolled postpartum women in Lusaka, Zambia, who identified home supporters. At visit 1, WLWH were interviewed about current practices. At visit 2, WLWH and home supporters received tailored EBF, responsive care, and ART adherence counseling. At visit 3, WLWH and home supporters were interviewed about their experiences trying recommended practices for 2-3 weeks. Interview transcripts were analyzed thematically. Participants included 23 WLWH, 15 male partners, and 8 female family members. WLWH reported several barriers to EBF. The most common were fear of HIV transmission via breastfeeding-despite high ART adherence-and insufficient breastmilk. After counseling, WLWH reported less fear of HIV transmission and improved breastfeeding practices. Home supporters reported providing WLWH increased support for EBF and ART adherence and practicing responsive caregiving. Both male and female home supporters appreciated being included in counseling and more involved in caregiving, and WLWH valued the increased support. Families with CHEU need focused support. Tailored counseling and family support for WLWH show promise for improving EBF, responsive caregiving, and ART adherence.

Abstract
Botswana has an adult HIV prevalence of 20.8% and annual incidence of 0.2%. We aimed to evaluate current practices and advance recommendations for treatment partners (informal adherence supporters) for people with HIV in Botswana. In January-February 2020, we conducted seven focus groups with 36 healthcare providers at seven HIV clinics in Gaborone, Botswana. Providers perceived treatment partners to be critical for quality patient care. They shared that in the new era of universal antiretroviral therapy (ART) initiation immediately after diagnosis ("test-and-treat"), providers no longer require patients to select treatment partners at ART initiation. Providers suggested a renewed emphasis on treatment partners. They believed that standard guidance for providers around treatment partner selection would ensure that providers cover similar topics across patients and endorsed implementation of workshops to educate treatment partners on how to support patients. However, streamlined ART initiation policies require innovative strategies, including eHealth interventions, to engage treatment partners.

Abstract
Background In the test and treat initiative, high-risk populations are screened for human immunodeficiency virus (HIV) infection and start early treatment if diagnosed positive. This study explores factors associated with willingness to initiate testing and immediate treatment among men who have sex with men (MSM) in Nairobi and its environs. The study was informed by a conceptual framework combining the AIDS Risk Reduction Model (ARRM) and the Modified Social Ecological Model. Methods This cross-sectional exploratory study targeted MSM (aged 18-60 years) reporting active engagement in anal or oral sex with men in Nairobi and its surrounding areas. Purposive sampling was used to identify data collection sites, and then snowballing was employed to reach the respondents. Data analysis was performed using SPSS version 23, and binary logistics regression was used for inferential analysis. Results Between July 2018 and June 2019, 391 MSM were recruited to fill out a self-administered questionnaire, out of which 345 complete questionnaires were analyzed. Never been tested for HIV, private/NGO as the facility of the last HIV test, and had unprotected anal sex were listed as the reasons for taking the most recent test, and the results of the most recent HIV test and seeking a post self-test confirmation were associated with a higher likelihood of accepting the immediate HIV test and treat initiative. Additionally, a preference for a health provider as the first source of support, belief in the efficacy of ARVs, and disclosure about being on ART were the other reasons. Additionally, being aged 25+ years, having more than 60 USD monthly income, and having inconsistent condom use during sex were associated with a higher likelihood of accepting the immediate HIV test and treat initiative. Barriers to the immediate test and treat strategy included stigma from healthcare providers and concerns about disruptions in lifestyle through antiretroviral therapy (ART) use. Conclusion Interventions aimed at increasing the HIV test and treat initiative in Kenya may need to take into account the demographic and social characteristics of MSM, including age, lack of habitual HIV testing, and lifestyle changes before and upon enrollment in ART. Projects should also consider working closely with healthcare facilities to strengthen treatment preparation, especially for asymptomatic MSM and those who may not be immediately willing to choose the test and treat strategy.

Abstract
Adolescents and young people in sub-Saharan Africa (SSA) experience high rates of gender-based violence (GBV). The whole school approach (WSA) is an established benchmark of effective school-based interventions to address this issue. We conducted a systematic review of peer-reviewed literature using PubMed/Medline, EMBASE, Scopus, Web of Science, Cochrane Library, Clinicaltrials.gov, and Google Scholar (1) to determine the characteristics, measured outcomes, and effectiveness of school-based GBV interventions and (2) to examine each papers' alignment with WSA and methodological quality. We developed a comprehensive intervention characteristics form for data extraction and analyzed the selected studies' quality using the modified Methodological Quality Rating Scale. To measure alignment with WSA implementation standards, we expanded the application of the WSA by creating the Whole School Approach Rating Scale (WSARS) for assessing school-based GBV interventions. Most interventions (n = 14/16) we reviewed effectively addressed at least one of the three outcomes of interest (i.e., sexual violence, physical violence, and GBV-related knowledge/attitudes). Over half (n = 9/16) of the studies were rated high on the WSARS. However, we observed no significant differences in effectiveness between studies rated high and those rated low on the WSARS. Our results indicate that school-based GBV interventions could be an effective and sustainable strategy for addressing GBV in and around schools.

Abstract
BACKGROUND The HIV/AIDS pandemic remains a significant public health issue, with sub-Saharan Africa (SSA) at its epicentre. Although antiretroviral therapy (ART) has been introduced to decrease new infections and deaths, SSA reports the highest incidence of HIV/AIDS, constituting two-thirds of the global new infections. This review aimed to elucidate the predominant barriers and facilitators influencing ART adherence and to identify effective strategies to enhance ART adherence across SSA. METHODS A comprehensive review was conducted on studies examining barriers to ART adherence and interventions to boost adherence among HIV-positive adults aged 15 and above in SSA, published from January 2010 onwards. The research utilized databases like Medline Ovid, CINAHL, Embase, and Scopus. Included were experimental and quasi-experimental studies, randomized and non-randomized controlled trials, comparative before and after studies, and observational studies such as cross-sectional, cohort, prospective and retrospective studies. Two independent reviewers screened the articles, extracted pertinent data, and evaluated the studies' methodological integrity using Joanna Briggs Institute's standardized appraisal tools. The compiled data underwent both meta-analysis and narrative synthesis. RESULTS From an initial pool of 12,538 papers, 45 were selected (30 for narrative synthesis and 15 for meta-analysis). The identified barriers and facilitators to ART adherence were categorized into seven principal factors: patient-related, health system-related, medication-related, stigma, poor mental health, socioeconomic and socio-cultural-related factors. Noteworthy interventions enhancing ART adherence encompassed counselling, incentives, mobile phone short message service (SMS), peer delivered behavioural intervention, community ART delivery intervention, electronic adherence service monitoring device, lay health worker lead group intervention and food assistance. The meta-analysis revealed a statistically significant difference in ART adherence between the intervention and control groups (pooled OR = 1.56, 95%CI:1.35-1.80, p = <0.01), with evidence of low none statistically significant heterogeneity between studies (I2 = 0%, p = 0.49). CONCLUSION ART adherence in SSA is influenced by seven key factors. Multiple interventions, either standalone or combined, have shown effectiveness in enhancing ART adherence. To optimize ART's impact and mitigate HIV's prevalence in SSA, stakeholders must consider these barriers, facilitators, and interventions when formulating policies or treatment modalities. For sustained positive ART outcomes, future research should target specific underrepresented groups like HIV-infected children, adolescents, and pregnant women in SSA to further delve into the barriers, facilitators and interventions promoting ART adherence.

Cultivating resilience and hope: A qualitative study of a pilot program using patient navigators to assist men who have sex with men with retention in the HIV care continuum in Uganda. PLOS GLOBAL PUBLIC HEALTH 2023; 3:e0001475.

Abstract
In Uganda, due to the criminalization of same-sex sexual practices, men who have sex with men (MSM) experience barriers to accessing HIV care. To retain patients within the HIV Care Continuum, some health interventions have used patient navigators as an ancillary support service. To understand the potential care benefits of using patient navigators for marginalized populations experiencing challenges to HIV care and treatment access in a Ugandan context, this qualitative study explored the experiences of newly diagnosed MSM using patient navigators for ARV retention in care in Kampala. Additionally, to gain insight into the feasibility of patient navigator interventions, this study also aimed to understand the perspectives and experiences of patient navigators working with HIV positive MSM. Individual in-depth, semi structured interviews were conducted with 24 HIV positive MSM and four patient navigators that were part of a patient navigator pilot program from January 2019 -December 2020. Analysis was done using manifest and latent qualitative content analysis. Results showed that HIV positive MSM in Uganda experienced a variety of social, emotional, and financial challenges that placed them at risk for dropping off the HIV Care Continuum. Patient navigators provided HIV positive MSM with the skills, support, and resources necessary to overcome these challenges. Based on study results, we conclude that within the patient navigator pilot program, patient navigators improved MSM participants' quality of life by helping them to achieve the HIV Care Continuum stages: diagnosis, linked to care, receiving HIV treatment, and retention in care. Study results suggest future research is needed on the psychosocial support needs of patient navigators, how the support needs of MSM change throughout their lifetime on the HIV Care Continuum, and how potential benefits of patient navigators may differ in rural Ugandan contexts.

Transmission reduction, health benefits, and upper-bound costs of interventions to improve retention on antiretroviral therapy: a combined analysis of three mathematical models. Lancet Glob Health 2022; 10:e1298-e1306.

Abstract
BACKGROUND In this so-called treat-all era, antiretroviral therapy (ART) interruptions contribute to an increasing proportion of HIV infections and deaths. Many strategies to improve retention on ART cost more than standard of care. In this study, we aimed to estimate the upper-bound costs at which such interventions should be adopted. METHODS In this combined analysis, we compared the infections averted, disability-adjusted life-years (DALYs) averted, and upper-bound costs of interventions that improve ART retention in three HIV models with diverse structures, assumptions, and baseline settings: EMOD in South Africa, Optima in Malawi, and Synthesis in sub-Saharan African low-income and middle-income countries (LMICs). We modelled estimates over a 40-year time horizon, from a baseline of Jan 1, 2022, when interventions would be implemented, to Jan 1, 2062. We varied increment of ART retention (25%, 50%, 75%, and 100% retention), the extent to which interventions could be targeted towards individuals at risk of interrupting ART, and cost-effectiveness thresholds in each setting. FINDINGS Despite simulating different settings and epidemic trends, all three models produced consistent estimates of health benefit (ie, DALYs averted) and transmission reduction per increment in retention. The range of estimates was 1·35-3·55 DALYs and 0·12-0·20 infections averted over the 40-year time horizon per additional person-year retained on ART. Upper-bound costs varied by setting and intervention effectiveness. Improving retention by 25% among all people receiving ART, regardless of risk of ART interruption, gave an upper-bound cost per person-year of US$2-6 in Optima (Malawi), $43-68 in Synthesis (LMICs in sub-Saharan Africa), and $28-180 in EMOD (South Africa). A maximally targeted and effective retention intervention had an upper-bound cost per person-year of US$93-223 in Optima (Malawi), $871-1389 in Synthesis (LMICs in sub-Saharan Africa), and $1013-6518 in EMOD (South Africa). INTERPRETATION Upper-bound costs that could improve ART retention vary across sub-Saharan African settings and are likely to be similar to or higher than was estimated before the start of the treat-all era. Upper-bound costs could be increased by targeting interventions to those most at risk of interrupting ART. FUNDING Bill & Melinda Gates Foundation.

Young people living with HIV (YPLH) are at risk for poor treatment adherence. Short message service (SMS) interventions can improve adherence, yet few exist for YPLH. Our study investigated preferences for a game-based SMS intervention among YPLH in Ghana. Thirty-two YPLH, ages 18 to 24, were recruited from an HIV clinic to complete in-depth interviews. Content analysis of interview data revealed areas of technology use relevant to intervention implementation, including mobile communication preferences, internet access, and mobile game use. Participants reported high perceived utility towards intervention features: treatment reminders, gamification components, and involvement of supportive individuals (e.g., providers). Issues with privacy, literacy, and cultural/developmental appropriateness were among concerns raised. Suggestions were made for strengthening basic SMS features (e.g., using code words to protect privacy) and incorporating advanced features (e.g., simplifying game interactions). This novel approach may help engage YPLH in HIV care if carefully developed with attention towards its mechanisms and user preferences.

Adherence barriers and interventions to improve ART adherence in Sub-Saharan African countries: A systematic review protocol. PLoS One 2022; 17:e0269252. [PMID: 35704636 PMCID: PMC9200354 DOI: 10.1371/journal.pone.0269252] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2022] [Accepted: 05/17/2022] [Indexed: 12/02/2022] Open
Abstract
Background The HIV/AIDS pandemic continues to be a major public health concern, particularly in Sub-Saharan Africa (SSA). Despite efforts to reduce new infections and deaths with the use of antiretroviral therapy (ART), SSA countries continue to bear the heaviest burden of HIV/AIDS globally, accounting for two-thirds of global new infections. The goal of this review is to identify common barriers to ART adherence as well as common effective interventions that can be implemented across SSA countries to improve ART adherence. Methods A systematic review of published studies on adult HIV-positive patients aged 15 or above, that have assessed the barriers to ART adherence and interventions improving patients’ adherence to ART in SSA countries shall be conducted. We will conduct electronic searches for articles that have been published starting from January 2010 onwards. The databases that shall be searched will include Medline Ovid, CINAHL, Embase, and Scopus. The review will include experimental and quasi-experimental studies such as randomized and non-randomized controlled trials as well as comparative before and after studies, and observational studies—cross-sectional studies, cohort studies, prospective and retrospective studies. Two independent reviewers will screen all identified studies, extract data and appraise the methodological quality of the studies using standard critical appraisal tools from the Joanna Briggs Institute. The extracted data will be subjected to a meta-analysis and narrative synthesis. Discussion This review will synthesize existing evidence on ART adherence barriers and strategies for improving patient adherence to ART in SSA countries. It will identify common barriers to adherence and common interventions proven to improve adherence across SSA. We anticipate that the findings of this review will provide information policy makers and stakeholders involved in the fight against HIV, will find useful in deriving better ways of not only retaining patients on treatment but having them adhere to their treatment. Review registration This protocol has been registered with the International Prospective Register of Systematic Reviews (PROSPERO); registration number CRD42021262256.

Abstract
There is an urgent need for greater provision of mental health services to people living with HIV. HIV testing and counselling (HTC) sessions diagnose HIV and offer appropriate psychosocial support and behavioural messages to support people to link into HIV care. It is not known to what extent HTC currently addresses mental health. We examined transcriptions of 116 audio-recorded HTC sessions delivered in Uganda against a checklist of mental health techniques. Hierarchical cluster analysis explored co-occurrence of techniques. Core counselling skills were very commonly present, and co-occurred. Assessment techniques were not commonly seen. Specific therapy techniques to treat anxiety or depression were not present. HTC staff are a resource for delivering mental health care for people with HIV, owing to their strong fundamental counselling skills. However, training is needed in assessment and evidence-based therapies. Provision of fuller assessment and interventions may increase detection and signposting for mental health and alcohol use, both of which may affect linkage into care. HTC staff have fundamental skills that could also be developed to train and supervise other staff to provide much needed mental health support to people living with HIV. Future research should develop brief mental health interventions for delivery by HTC staff.

Abstract
Retention in antiretroviral therapy (ART) services is critical to achieving positive health outcomes for individuals living with HIV, but accumulating evidence indicates that individuals are likely to miss ART appointments over time. Thus, it is important to understand why individuals miss appointments and how they re-engage in HIV care. We used in-depth interviews with 44 ART clients in Malawi who recently missed an ART appointment (> 14 days) but eventually re-engaged in care (within 60 days) to explore reasons for missed appointments and barriers and facilitators to re-engagement. We found that most individuals missed ART appointments due to unexpected life events such as funerals, work, and illness for both clients and their treatment guardians who were also unable to attend facilities. Several reasons differed by gender-work-related travel was common for men, while caring for sick family members was common for women. Barriers to re-engagement included continued travel, illness, and restricted clinic schedules and/or staff shortages that led to repeat facility visits before being able to re-engage in care. Strong internal motivation combined with social support and reminders from community health workers facilitated re-engagement in HIV care.

Offering ART refill through community health workers versus clinic-based follow-up after home-based same-day ART initiation in rural Lesotho: The VIBRA cluster-randomized clinical trial. PLoS Med 2021; 18:e1003839. [PMID: 34673765 PMCID: PMC8568187 DOI: 10.1371/journal.pmed.1003839] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2021] [Revised: 11/04/2021] [Accepted: 10/06/2021] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND Community-based antiretroviral therapy (ART) dispensing by lay workers is an important differentiated service delivery model in sub-Sahara Africa. However, patients new in care are generally excluded from such models. Home-based same-day ART initiation is becoming widespread practice, but linkage to the clinic is challenging. The pragmatic VIBRA (Village-Based Refill of ART) trial compared ART refill by existing lay village health workers (VHWs) versus clinic-based refill after home-based same-day ART initiation. METHODS AND FINDINGS The VIBRA trial is a cluster-randomized open-label clinical superiority trial conducted in 249 rural villages in the catchment areas of 20 health facilities in 2 districts (Butha-Buthe and Mokhotlong) in Lesotho. In villages (clusters) randomized to the intervention arm, individuals found to be HIV-positive during a door-to-door HIV testing campaign were offered same-day ART initiation with the option of refill by VHWs. The trained VHWs dispensed drugs and scheduled clinic visits for viral load measurement at 6 and 12 months. In villages randomized to the control arm, participants were offered same-day ART initiation with clinic-based ART refill. The primary outcome was 12-month viral suppression. Secondary endpoints included linkage and 12-month engagement in care. Analyses were intention-to-treat. The trial was registered on ClinicalTrials.gov (NCT03630549). From 16 August 2018 until 28 May 2019, 118 individuals from 108 households in 57 clusters in the intervention arm, and 139 individuals from 130 households in 60 clusters in the control arm, were enrolled (150 [58%] female; median age 36 years [interquartile range 30-48]; 200 [78%] newly diagnosed). In the intervention arm, 48/118 (41%) opted for VHW refill. At 12 months, 46/118 (39%) participants in the intervention arm and 64/139 (46%) in the control arm achieved viral suppression (adjusted risk difference -0.07 [95% CI -0.20 to 0.06]; p = 0.256). Arms were similar in linkage (adjusted risk difference 0.03 [-0.10 to 0.16]; p = 0.630), but engagement in care was non-significantly lower in the intervention arm (adjusted risk difference -0.12 [-0.23 to 0.003]; p = 0.058). Seven and 0 deaths occurred in the intervention and control arm, respectively. Of the intervention participants who did not opt for drug refill from the VHW at enrollment, 41/70 (59%) mentioned trust or conflict issues as the primary reason. Study limitations include a rather small sample size, 9% missing viral load measurements in the primary endpoint window, the low uptake of the VHW refill option in the intervention arm, and substantial migration among the study population. CONCLUSIONS The offer of village-based ART refill after same-day initiation led to similar outcomes as clinic-based refill. The intervention did not amplify the effect of home-based same-day ART initiation alone. The findings raise concerns about acceptance and safety of ART delivered by lay health workers after initiation in the community. TRIAL REGISTRATION Registered with Clinicaltrials.gov (NCT03630549).

Role of Support Reciprocity in HIV Viral Suppression Among People Living with HIV and Their Treatment Partners in Botswana. Int J Behav Med 2021; 29:367-376.

Abstract
BACKGROUND Social support reciprocity (the extent to which people exchange mutual support) is associated with long-term health. METHOD We examined whether overall social support and reciprocity of support between people living with HIV and their treatment partners (informal caregivers selected from patients' social networks to support adherence) are associated with HIV viral suppression. A total of 130 patients living with HIV and their treatment partners were recruited from a clinic in Gaborone, Botswana, from May 2016 to April 2017. Participants completed surveys assessing sociodemographic and social network characteristics. Patients and treatment partners rated their emotional closeness to each other (not at all close = 0, somewhat close = 1, very close = 2). RESULTS Multivariable logistic regressions indicated a significantly higher likelihood of viral suppression among patients who reported greater average emotional closeness to social network members. The likelihood of viral suppression was lower in asymmetric relationships in which patients felt closer to treatment partners than treatment partners felt to them (compared to when treatment partners felt closer to patients); this negative effect was strongest in dyads with female treatment partners and male patients. Follow-up analyses additionally indicated that asymmetric relationships in which treatment partners felt closer to patients were as protective as symmetric relationships, in which patients and treatment partners felt equally close. CONCLUSION Perceptions around reciprocity may matter as much as overall relationship closeness in patients' health outcomes. Interventions to improve the support of informal caregivers could help to improve relationship quality and health outcomes among people with HIV.

Abstract
Despite the Universal Test and Treat program and widespread antiretroviral treatment rollout, South Africa is still facing HIV prevention and treatment challenges, which are aggravated by human resource shortages in the healthcare sector. Individual- and community-level responses to these HIV-related challenges are increasingly being explored, for example, in community and home-based care. The role of the household as a crucial mediating social level has, however, largely been omitted. This paper outlines the design of an intervention to stimulate the involvement of the household in support for people living with HIV in South Africa. The 6SQuID model guided the intervention development process in four phases: (1) formative research, theory formulation, and a review of the existing literature, (2) integration of the results from the formative research into the "Positive Communication Process" (P2CP model) as a mechanism of change, (3) design of a community-health-worker-led intervention as the way to deliver the change mechanism, and (4) testing and revision of the developed intervention material-called Sinako-in a small-scale pilot study. The Sinako intervention anticipates that the future of chronic HIV care in resource-constrained settings will need to integrate the patient's household into the fight against HIV.
