Human Immunodeficiency Virus (HIV) Care Continuum Outcomes After Transition to Adult Care Among a Prospective Cohort of Youth With HIV in Atlanta, Georgia.

BACKGROUND: Healthcare transition from pediatric to adult-oriented clinical settings is often viewed as a high-risk time for care disengagement. However, there is a paucity of prospective, longitudinal research documenting human immunodeficiency virus (HIV) care outcomes after healthcare transition. METHODS: We conducted a prospective, observational cohort study of healthcare transition among youth enrolled at an HIV care center in Atlanta, Georgia. Pediatric clinic patients (average age, 24 years) were enrolled up to 3 months before the expected transition and were followed up to determine linkage, retention, and viral suppression in adult care through electronic medical record abstractions at the baseline and at 6, 12, 18, and 24 months. RESULTS: The majority of our cohort (n = 70) was male (88.6%) and black (92.9%) and acquired HIV horizontally (80%). Most of our cohort was linked to adult care by 12 months (84%) after enrollment. Of those who linked to adult care by 12 months, retention rates were 86% (95% confidence interval, 78%-94%) at 6 months, 76% (66%-86%) at 12 months, and 66% (55%-78%) at 18 and 24 months. Once in adult care, the proportion with viral suppression was stable (73% at baseline and 74%, 77%, 67%, and 78% at 6, 12, 18, and 24 months, respectively). CONCLUSIONS: Although most youth successfully linked to adult care, retention rates decreased over the 24-month follow-up period. Rates of viral suppression were stable for those who remained in care. Strategies to support retention in adult care will be critical to optimizing this transition for youth with HIV.

Challenges and Fears of Adolescents and Young Adults Living with HIV Facing Transition to Adult HIV Care.

Adolescents and young adults living with perinatally-acquired HIV (AYLPHIV) have poor outcomes along each step of the HIV care continuum due to challenges in seeking care and advocating for themselves. The transition from paediatric to adult HIV care is a particularly high-risk period for AYLPHIV in rural Uganda. We conducted in-depth interviews with AYLPHIV (n = 30), caregivers (n = 10), and healthcare providers (n = 10) to understand challenges facing AYLPHIV during the transition from paediatric to adult HIV care. Themes were identified by thematic content analysis. Transition-related challenges and fears included difficulty navigating the adult HIV clinic; loss of informational support; long wait times at the adult HIV clinic; lack of privacy, and fear of HIV status disclosure and stigma; and loss of support from caregivers, and health care providers. Before transitioning to adult HIV care, AYLPHIV should be adequately prepared and given appropriate information to help them navigate adult HIV care.

Addressing the Know-Do Gap in Adolescent HIV: Framing and Measuring Implementation Determinants, Outcomes, and Strategies in the AHISA Network.

Implementation science (IS) uses systematic methods to close gaps between research and practice by identifying and addressing barriers to implementation of evidence-based interventions (EBIs). To reach UNAIDS HIV targets, IS can support programs to reach vulnerable populations and achieve sustainability. We studied the application of IS methods in 36 study protocols that were part of the Adolescent HIV Prevention and Treatment Implementation Science Alliance (AHISA). Protocols focused on youth, caregivers, or healthcare workers in high HIV-burden African countries and evaluated medication, clinical and behavioral/social EBIs. All studies measured clinical outcomes and implementation science outcomes; most focused on early implementation outcomes of acceptability (81%), reach (47%), and feasibility (44%). Only 53% used an implementation science framework/theory. Most studies (72%) evaluated implementation strategies. Some developed and tested strategies, while others adapted an EBI/strategy. Harmonizing IS approaches allows cross study learning and optimization of delivery of EBIs and could support attainment of HIV goals.

Systematic Review of mHealth Interventions for Adolescent and Young Adult HIV Prevention and the Adolescent HIV Continuum of Care in Low to Middle Income Countries.

Adolescents and young adults (AYA) in low to middle income countries (LMIC) have poorer outcomes along each step in the HIV continuum of prevention and care compared to younger children or older adults. The use of mHealth technology provides a potentially promising implementation strategy for interventions to remedy these disparities. We therefore conducted a systematic review of the English literature and conference proceedings from January 1, 2000 to April 1, 2021 evaluating mHealth interventions targeting AYA along each step of the HIV continuum of care in LMIC. We identified 27 mHealth interventions across the HIV continuum, with no interventions addressing transition from pediatric to adult care. The majority of studies were single arm, uncontrolled or underpowered, with few randomized trials resulting in mixed and inconclusive outcomes. mHealth interventions have potential to remedy disparities along the HIV continuum of care for AYA in LMIC but larger, powered randomized trials are needed.

RESUMEN: Los adolescentes y adultos jóvenes (AYA) en países de ingresos bajos a medianos (LMIC) tienen peores resultados en cada paso del continuo de prevención y atención del VIH en comparación con los niños más pequeños o los adultos mayores. El uso de la tecnología mHealth proporciona una estrategia de implementación potencialmente prometedora para las intervenciones para remediar estas disparidades. Por lo tanto, realizamos una revisión sistemática de los resúmenes y artículos publicados en inglés desde el 1 de enero de 2000 hasta el 1 de abril de 2021 para evaluar las intervenciones de mHealth dirigidas a AYA a lo largo de cada paso del continuo de atención del VIH en LMIC. Identificamos 27 intervenciones de mHealth en todo el continuo del VIH, sin intervenciones que abordaran la transición de la atención pediátrica a la de adultos. La mayoría de los estudios fueron de un solo brazo, no controlados o con bajo poder estadístico, con pocos ensayos aleatorios que dieron resultados mixtos y no concluyentes. Las intervenciones de mHealth tienen el potencial de remediar las disparidades a lo largo de la continuidad de la atención del VIH para AYA en LMIC, pero se necesitan ensayos aleatorios más grandes y potentes.

Impact of COVID-19 on Adolescent HIV Prevention and Treatment Services in the AHISA Network.

We investigated perceived impacts of COVID-19 on the delivery of adolescent HIV treatment and prevention services in sub-Saharan Africa (SSA) by administering a survey to members of the Adolescent HIV Prevention and Treatment Implementation Science Alliance (AHISA) from February to April 2021. We organized COVID-19 impacts, as perceived by AHISA teams, under three themes: service interruptions, service adjustments, and perceived individual-level health impacts. AHISA teams commonly reported interruptions to prevention programs, diagnostic testing, and access to antiretroviral therapy (ART). Common service adjustments included decentralization of ART refills, expanded multi-month ART distribution, and digital technology use. Perceived individual-level impacts included social isolation, loss to follow-up, food insecurity, poverty, and increases in adolescent pregnancies and sexually transmitted infections. The need for collaboration among stakeholders were commonly cited as lessons learned by AHISA teams. Survey findings highlight the need for implementation science research to evaluate the effects of pandemic-related HIV service adaptations in SSA.

Intrapersonal predictors of internalized stigma among school going adolescents living with HIV in southwestern Uganda.

We assessed the association between internalized HIV stigma, resilience, health locus of control, coping self-efficacy and empowerment among adolescents living with HIV in Uganda. We conducted a cross-sectional study between August and October 2020 among 173 adolescents aged 13-18 years attending Mbarara Regional Referral Hospital's HIV clinic. We used linear regression to determine the association between HIV stigma and intrapersonal factors adjusting for sociodemographic characteristics. The median age of the participants was 16 (IQR 3) years. There was a negative correlation between HIV stigma and resilience (ß= -0.03, p < 0.001), internal health locus of control (ß= -0.095, p < 0.001) and coping self-efficacy (ß= -0.02, p < 0.001), while empowerment was positively correlated (ß = 0.07, p < 0.001) with HIV stigma. After adjusting for the intrapersonal factors (resilience, health locus of control, coping self-efficacy and empowerment) and socio-demographic characteristics (education level and boarding school), only internal health locus of control (ß=-0.044, p = 0.016) and coping self-efficacy (ß=-0.015, p < 0.001) remained significantly correlated with HIV stigma. The findings suggest that interventions focusing on intrapersonal factors such as internal locus of control, empowerment and resilience may contribute towards reduction of HIV stigma among adolescents in boarding schools.

Development of a transition readiness score for adolescents living with perinatally-acquired HIV and transitioning to adult care.

We created a transition readiness score for adolescents with perinatally-acquired HIV as they transition from pediatric to adult care. Of the 199 adolescents who transitioned to adult care, 84 (42%) had viral suppression (< 200 copies/ml) one year after transition. Adolescents on first-line ART, with documented HIV status disclosure, and higher rating on the HIV Adolescent Readiness to Transition Scale had significantly higher odds of viral suppression after transition. Conversely, females, those with older age at ART initiation, and those with prior alcohol use had significantly lower odds of viral suppression after transition. Using these data, we created a transition readiness score organized into low, intermediate, and high levels of transition readiness. This transition readiness score can be used to identify adolescents who are likely ready to transition to adult care and identify additional areas for intervention to improve the likelihood of successful transition for those with lower transition readiness scores.

"I am not shy anymore": A qualitative study of the role of an interactive mHealth intervention on sexual health knowledge, attitudes, and behaviors of South African adolescents with perinatal HIV.

BACKGROUND: South Africa has one of the highest burdens of adolescents with perinatally-acquired HIV (APHIV) in the world. APHIV in South Africa have limited access to sexual and reproductive health (SRH) education and services specific to their HIV status. When lacking comprehensive SRH education, APHIV are prone to sexual risk behaviors that can lead to unintended pregnancy, sexually transmitted infections, and HIV transmission. The use of mHealth interventions has been shown to deliver information, foster social support, and improve decision-making skills. In this study, we evaluate how an mHealth intervention influences sexual health knowledge and behaviors in APHIV. METHODS: We purposively enrolled adolescents from the intervention arm of a randomized clinical trial assessing a multi-module, moderated WhatsApp-based intervention-Interactive Transition Support for Adolescents Living with HIV (InTSHA)-within a government supported clinic in KwaMashu, an urban township of KwaZulu-Natal, South Africa. We conducted in-depth interviews based on World Health Organization guidelines for asking adolescents about SRH. We thematically analyzed data through an iterative, team-based coding approach combining deductive and inductive elements to contextualize SRH attitudes, knowledge, and behaviors before and after receiving the InTSHA intervention. RESULTS: Of the 21 participants, 13 (61.9%) were female and the mean age was 16.6 years. Most participants reported first learning about SRH as young teenagers in school through non-targeted and negative ways, seeking clarification through peers and the internet rather than clinicians or caregivers. Participants reported that InTSHA provided a holistic perspective on relationships, gender, and sexuality specific to growing up with HIV in South Africa. They praised the ability to give and receive information from peers in a moderated setting through the mHealth intervention, building their confidence, decision-making skills, and communication with partners and caregivers throughout their everyday lives. Despite reporting some technological challenges, adolescents agreed that InTSHA was convenient, confidential, and user-friendly. CONCLUSIONS: South African APHIV receive incomplete and conflicting sexual education from peers, caregivers, teachers, and technology that can be supplemented by mHealth curricula targeted for the unique needs of APHIV. Future, scaled-up mHealth interventions can lower SRH stigma by expanding access to sexual education and peer support, supplementing adolescents' existing SRH education.

South African adolescents with perinatally-acquired HIV (APHIV)­teenagers who were born with HIV­lack access to sexual and reproductive health (SRH) education specific to their HIV status. Ineffective SRH education often leads to risky behaviors (such as unprotected sex), teenage pregnancy, and the spread of HIV. Mobile health (mHealth) interventions, such as phone apps, can help improve adolescent SRH knowledge and decision-making. In this study, we evaluate how a WhatsApp-based intervention­Interactive Transition Support for Adolescents Living with HIV (InTSHA)­influences SRH attitudes and behaviors of APHIV. InTSHA involved long-term, weekly group chats of APHIV, run by trained facilitators, that included two modules discussing SRH. This study analyzes in-depth interviews we conducted with adolescents who completed InTSHA, asking them about their SRH knowledge and behaviors before and after the intervention. The interviews took place in a government-supported clinic in an urban township of KwaZulu-Natal. Interviews were recorded, transcribed, translated, coded, and analyzed. Of 21 participants, 13 were female and the average age was 16.6 years. Most participants reported first learning about SRH as young teenagers in school, through peers, or on the internet, rather than through healthcare workers or family members. Participants reported that InTSHA provided a comfortable platform to discuss relationships, gender, and sexuality as APHIV. Adolescents enjoyed giving and receiving information from peers in a moderated setting. They reported that InTSHA built their confidence, decision-making skills, and communication with partners and caregivers. South African SRH education for APHIV can be supplemented by targeted mHealth interventions.

Disclosure, Social Support, and Mental Health are Modifiable Factors Affecting Engagement in Care of Perinatally-HIV Infected Adolescents: A Qualitative Dyadic Analysis.

Adolescents living with perinatally acquired HIV in South Africa face significant barriers to successful transition from pediatric to adult care. We performed in-depth qualitative interviews with 41 adolescents living with HIV and 18 of their caregivers to investigate modifiable factors to improve engagement in care prior to transition to adult care. Based on dyadic, inductive content analysis, findings suggest that HIV status disclosure, social support, and mental health are targets for improvement in engagement in care. Early disclosure and a sense of belonging facilitated engagement in care, while barriers included delayed or inadequate disclosure, denial, and lack of disclosure to others. Adherence support improved by having a biological mother as a direct supervisor. Barriers to care included changing caregivers, abandonment, undiagnosed mental health problems and learning difficulties. Despite these factors, the majority of adolescents showed resilience and remained engaged in care despite difficult circumstances.

Barriers to Retention in Care are Overcome by Adolescent-Friendly Services for Adolescents Living with HIV in South Africa: A Qualitative Analysis.

To assess facilitators and barriers to retention in care for adolescents living with HIV, we conducted in-depth, semi-structured interviews with adolescents ages 13 to 24 years who were living with HIV and being cared for in either an adolescent-friendly or standard government-supported clinic in KwaZulu-Natal, South Africa. We used inductive content analysis approach based on grounded theory derived from reviewing, coding, and interpreting data. We interviewed 28 adolescents living with HIV (16 in the adolescent clinic and 12 from the pediatric clinic) and 14 of their caregivers. Barriers to retention in care included having to attend clinic during school hours, fear of disclosure to others, social isolation, and conflict with clinical staff. Facilitators to retention in care seen in the adolescent-friendly services clinic included after school clinic hours, peer support, and connection to the clinical staff. Adolescent-friendly services are facilitators of HIV care and warrant prioritization in treatment programs.

Impact of a clinical program using weekly Short Message Service (SMS) on antiretroviral therapy adherence support in South Africa: a retrospective cohort study.

BACKGROUND: In randomized controlled trials, short message service (SMS) programs have improved adherence to HIV antiretroviral therapy (ART). In response, the World Health Organization recommended use of SMS programs to support ART. However, there is limited data on real-world implementations of SMS programs. METHODS: We conducted a retrospective cohort study of an SMS program to improve ART adherence in a government-run HIV clinic in rural South Africa. We analyzed data from all adult patients who 1) enrolled at the clinic before the observation period (July 2013 through June 2014), 2) had ≥1 ART prescriptions in the observation period, and 3) had data on phone number availability (N = 2255). Our main outcome measure was prescription coverage, defined as the presence of a valid ART prescription for each day observed. We fit generalized linear mixed models adjusted for pre-program prescription coverage, demographics, and ART duration, dosing, and regimen. RESULTS: Exposure to the SMS program was independently associated with greater prescription coverage (AOR = 1.23, 95% CI 1.13-1.34, P < 0.001) compared with non-exposure, although the absolute increase in prescription coverage was small (4.7 days of ART prescription coverage per average patient per year). Among a subset of patients (n = 725) whose pre-program prescription coverage was <100%, the corresponding mean expected absolute increase in prescription coverage was 8.2 days per year. CONCLUSIONS: Our primary finding was that an SMS reminder program implemented in routine clinical care was associated with a small increase in prescription coverage of uncertain clinical significance.

A qualitative analysis of self-management needs of adolescents and young adults living with perinatally acquired HIV in rural, southwestern Uganda.

The number of adolescents living with HIV remains high in sub-Saharan Africa with poorer HIV treatment outcomes among adolescents and young adults compared to individuals in other age groups. For adolescents and young adults living with perinatally acquired HIV (AYLPHIV), the transition from pediatric to adult HIV care is a particularly high-risk period. We conducted a qualitative study to understand self-management needs of AYLPHIV in rural, southwestern Uganda as they prepare to transition to adult HIV care in order to inform relevant interventions that can enable AYLPHIV acquire the necessary skills to manage their illness as they age into adulthood. We conducted 60 in-depth interviews with AYLPHIV (n = 30), caregivers (n = 20) and health care providers (n = 10) from the HIV clinic at Mbarara Regional Referral Hospital. We used an interview guide that focused on perceptions about transition to adult HIV care, challenges with transitioning, navigating HIV care, and self-management needs for AYLPHIV (from the perspectives of AYLPHIV, their caregivers, and health care providers). We used thematic analysis to identify themes related to AYLPHIV's self-management skills. We identified several self-management needs that we grouped under two major themes; social support and empowerment for AYLPHIV to assume responsibility for their own health and to navigate adult HIV care independently. The sub-themes under social support were information support, instrumental support, and emotional support as the sub themes while sub-themes under empowerment included self-advocacy skills, interpersonal skills, self-care skills, and disclosure skills. Taken together, these findings indicate that AYLPHIV need to be supported and empowered to maximize their chances of successfully transitioning to adult HIV care. Support comes from peers and caregivers. AYLPHIV require knowledge about their HIV status and empowerment with different skills including: self-advocacy skills, interpersonal skills, self-care skills, and HIV status disclosure skills, in order to assume responsibilities related to independent HIV care.

High risk injection drug use and uptake of HIV prevention and treatment services among people who inject drugs in KwaZulu-Natal, South Africa.

The use of injection drugs in South Africa is increasing. HIV prevention, treatment and addiction services for people who inject drugs (PWID) in South Africa are not well documented. We conducted a mixed-methods study to understand current drug use practices and access to HIV prevention and treatment services for PWID in KwaZulu-Natal, South Africa. We used respondent-driven sampling to recruit 45 people who reported injecting opiates within the past 6 months from Durban, KwaZulu-Natal, South Africa. We found high rates of practices that increase HIV/viral hepatitis risk including the use of shared needles (43%) and direct blood injections (bluetoothing) (18%). Despite 35% of participants living with HIV, only 40% accessed antiretroviral therapy within the past year, and one accessed PrEP. None of the participants reported ever testing for Hepatitis C.

A qualitative assessment of the perceived acceptability and feasibility of eHARTS, a mobile application for transition readiness assessment for adolescents living with HIV in South Africa.

South Africa has the highest burden of adolescents living with HIV (ALHIV) in the world. The transition from pediatric to adult centered HIV care is a vulnerable period during which many clinical outcomes of ALHIV suffer. Transition readiness assessments may help ALHIV transition from pediatric to adult care to improve their health outcomes. Here, we evaluated the perceived acceptability and feasibility of a mobile health (mHealth) application, eHARTS, to determine transition readiness for ALHIV in South Africa. We conducted in-depth interviews with adolescents (n = 15) and healthcare providers (n = 15) at three government-supported hospitals in KwaZulu-Natal, South Africa. We used a semi-structured interview guide comprising of open-ended questions based on the unified theory of acceptance and use of technology. We did a thematic analysis of the data using an iterative, team-based coding approach to develop themes that were representative of the participants' perspectives on the acceptability and feasibility of eHARTS. We found that most participants found eHARTS to be acceptable because of its simplicity and lack of stigma. Participants believed eHARTS was feasible as it could easily be administered within a hospital setting and integrated into regular clinic activity without disrupting patient care. Additionally, eHARTS was found to have great utility for adolescents and healthcare providers. Clinicians saw it as a valuable tool to engage adolescents and prepare them for transition. Despite concerns that eHARTS may give adolescents a wrong impression about immediate transition, participants suggested that eHARTS be framed in an empowering way as they prepare for transition to adult care. Our data showed that eHARTS is a simple, mobile transition assessment tool with perceived acceptability and feasibility for use in HIV clinics in South Africa for ALHIV. It is particularly useful for ALHIV and transitioning to adult care as it can help identify gaps in readiness for transition.

High risk injection drug use and uptake of HIV prevention and treatment services among people who inject drugs in KwaZulu-Natal, South Africa.

We conducted a mixed-methods study to understand current drug use practices and access to healthcare services for people who use injection drugs in KwaZulu-Natal, South Africa. We used respondent-driven sampling to recruit 45 people who used injection drugs within the past 6 months from KwaZulu-Natal, South Africa. We found high rates of practices that increase HIV/viral hepatitis risk including the use of shared needles (43%) and direct blood injections (bluetoothing) (18%). Despite 35% living with HIV, only 40% accessed antiretroviral therapy within the past year, and one accessed PrEP. None of the participants ever tested for Hepatitis C.

A qualitative analysis examining intersectional stigma among young adults living with HIV in Atlanta, Georgia.

HIV-related stigma is a barrier to engagement in care for young adults living with HIV. Other intersecting forms of stigma (e.g., racism, sexism, homophobia), may worsen HIV-related stigma and impact engagement in care. From November 2020 to February 2021, we conducted 20 in-depth qualitative interviews among young adults living with HIV attending a large, comprehensive HIV care center in Atlanta, Georgia. Semi-structured interview guides based on Earnshaw and Chaudoir's HIV Stigma Framework and the theory of intersectionality facilitated discussion around experiences with various forms of stigma and its possible influence on healthcare engagement. Using the social-ecological model, we used thematic analysis to contextualize how young adults living with HIV experienced intersectional stigma and enacted, anticipated, and internalized HIV stigma in both healthcare and non-healthcare settings. Most participants identified as male, Black/African American, and gay. Participants described stigma at intrapersonal, interpersonal, clinic, and community levels. Intrapersonal stigma was associated with delayed care seeking, isolation, and fear of disclosure. Interpersonal stigma included discrimination from family and friends and avoidance of close relationships to elude disclosure. At the clinic level, stigma included negative experiences with staff in HIV and non-HIV healthcare settings, which contributed to decreased engagement in care. Stigma in the community included differential treatment from employers, community leaders, and religious community and was associated with feelings of helplessness related to current societal inequalities. Coping/motivating mechanisms for stigma included prioritizing health, eliciting support from the medical care team and peers. Our findings show different intersecting stigmas are barriers to healthcare at multiple levels for young adults living with HIV, potentially exacerbating existing health and social disparities. To improve engagement in care among young adults living with HIV, future interventions should address the different mechanisms of stigma at community, clinic, interpersonal and intrapersonal levels by enhancing social support and improving healthcare structural competency.

Severe Acute Respiratory Syndrome Coronavirus 2 Evolution and Escape From Combination Monoclonal Antibody Treatment in a Person With HIV.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) escape from combination monoclonal antibody treatment is rarely reported. We describe an immunocompromised individual with human immunodeficiency virus and persistent SARS-CoV-2 infection in whom substantial SARS-CoV-2 evolution occurred, including the emergence of 2 mutations associated with escape from the monoclonal antibody cocktail received.

Perspectives About Transition Readiness Among Adolescents and Young People Living With Perinatally Acquired HIV in Rural, Southwestern Uganda: A Qualitative Study.

ABSTRACT: Despite the availability of antiretroviral therapy, treatment outcomes are worse among adolescents and young adults living with perinatally acquired HIV (AYLPHIV). These disparities are magnified during the transition from pediatric to adult-based HIV care. We conducted in-depth interviews with AYLPHIV aged 15-24 years ( n = 30), their caregivers ( n = 10), and health care providers ( n = 10). All participants provided written assent and/or informed consent to enroll. Thematic content analysis was used to identify and analyze themes relevant to transition readiness. We grouped perspectives on transition readiness into 4 themes: preparation for transition, communication between stakeholders, social support, and timing of transition. AYLPHIV in sub-Saharan Africa who are facing a transition to adult HIV care should be equipped with relevant information about their illness, self-advocacy skills, and support from caregivers and health care providers to remain engaged in HIV care.

Mobile Phone-Based Intervention Among Adolescents Living With Perinatally Acquired HIV Transitioning from Pediatric to Adult Care: Protocol for the Interactive Transition Support for Adolescents Living With HIV using Social Media (InTSHA) Study.

BACKGROUND: Adolescents living with perinatally acquired HIV often have poor retention in care and viral suppression during the transition from pediatric to adult-based care. OBJECTIVE: The aim of this study is to evaluate a mobile phone-based intervention, Interactive Transition Support for Adolescents Living With HIV using Social Media (InTSHA), among adolescents living with perinatally acquired HIV as they transition from pediatric to adult care in South Africa. METHODS: InTSHA uses encrypted, closed group chats delivered via WhatsApp (Meta Platforms Inc) to develop peer support and improve communication between adolescents, their caregivers, and health care providers. The intervention is based on formative work with adolescents, caregivers, and health care providers and builds on several existing adolescent support programs as well as the Social-ecological Model of Adolescent and Young Adult Readiness for Transition (SMART). The final InTSHA intervention involves 10 modules conducted weekly through moderated WhatsApp group chats with adolescents and separately with their caregivers. We will randomly assign 80 South African adolescents living with perinatally acquired HIV who are aware of their HIV status and aged between 15 and 19 years to receive either the intervention (n=40) or standard of care (n=40). RESULTS: We will measure acceptability of the intervention as the primary outcome and evaluate feasibility and preliminary effectiveness for retention in care and viral suppression after completion of the intervention and at least 6 months after randomization. In addition, we will measure secondary outcomes evaluating the impact of the InTSHA intervention on peer support, self-esteem, depression, stigma, sexual education, connection to health care providers, and transition readiness. Enrollment began on April 15, 2021. As of December 31, 2021 a total of 78 out of expected 80 participants have been enrolled. CONCLUSIONS: If successful, the intervention will be evaluated in a fully powered randomized controlled trial with a larger number of adolescents from urban and rural populations to further evaluate the generalizability of InTSHA.
