Acceptability and feasibility of leveraging community-based HIV counselling and testing platforms for same-day oral PrEP initiation among adolescent girls and young women in Eastern Cape, South Africa

Study-to-Clinic Transition and Daily Oral PrEP Access Experiences Among AGYW in Eastern Cape, South Africa: Insights from the Community PrEP Study

Adolescent girls and young women (AGYW) face a high HIV burden, while PrEP persistence often declines post-trial. Understanding access outside research settings is key to improving study-to-clinic transitions. This study explored AGYW's experiences accessing PrEP in public clinics after The Community PrEP Study (CPS) in Eastern Cape, South Africa, a 24-month behavioral intervention. AGYW referred to clinics post-study (June-November 2021) were interviewed on their transition experiences. Interviewers categorized participants as PrEP continuation, discontinuation, or non-presentation. The qualitative team iteratively coded transcripts, used matrix analysis and discussions to examine referral experiences, clinic access, and PrEP motivations. While most accepted the transition, many missed study support. Continuation was linked to clinic adaptation, while discontinuation stemmed from access barriers. Non-presentation resulted from logistical and privacy concerns. Recommendations included youth-friendly provider training, alternative PrEP pick-up options, and service integration. Provider engagement and training remain critical for optimizing PrEP access, even with long-acting modalities.Trial registration number NCT03977181.

Alcohol Use and the Pre-exposure Prophylaxis Continuum of Care Among Men in Rural South Africa: Results from a Longitudinal Study

Despite freely available oral HIV pre-exposure prophylaxis (PrEP), HIV incidence among young men in South Africa remains high. This study explores the impact of alcohol use on PrEP initiation and continuation among South African men. We performed a secondary data analysis from a trial involving men aged 16-29, randomly selected in KwaZulu-Natal. Participants were referred to sexual health services, and those who were HIV negative and sexually active were offered oral PrEP. Alcohol consumption was categorized using AUDIT-C criteria as no/low risk (0-3) and hazardous alcohol use (4-12). Primary outcomes were PrEP initiation and continuation, defined as refilling prescriptions for ≥ 4 months. Logistic regression models adjusted for clinical and demographic confounders estimated relationships between PrEP initiation/continuation and alcohol use. Among 325 men analyzed, average age was 22.9 years (SD 3.6), with 146 (45%) reporting hazardous alcohol consumption. PrEP initiation was greatest among the hazardous/very-high risk group (40%), with the lowest uptake among men who do not use alcohol (17%). In multivariate analyses, those with hazardous alcohol use remained more likely to initiate PrEP compared to those with no/low risk alcohol use (aOR 1.96, 95%CI 1.13-3.40; p-value = 0.017). Only 27% (24/88) remained on PrEP at 4 months, with continuation similar between alcohol use groups (aOR 1.56, 95%CI: 0.47-5.12, p = 0.47). Hazardous alcohol use is prevalent among men in rural South Africa and associated with increased PrEP initiation. However, overall PrEP continuation was low and consistent across alcohol use levels. Hazardous alcohol use should not deter PrEP implementation efforts to engage young men.

Community PrEP delivery for adolescent girls and young women: insights from the DREAMS PrEP Choice Study in Johannesburg, South Africa

Introduction

Long-acting pre-exposure prophylaxis (PrEP) methods have the potential to significantly reduce HIV acquisition and increase the uptake and effective use of PrEP among adolescent girls and young women (AGYW). We describe the implementation approach for delivering the PrEP ring and outline provider perspectives related to community-based service delivery.

Methods

The DREAMS PrEP Choice Study, a mixed-methods implementation science study delivering PrEP choice to women 18 years and older, was conducted in Johannesburg, South Africa. We extracted quantitative enrollment data from the routine patient management system (REDCap) and collected qualitative data from four focus group discussions with providers. Quantitative data are presented descriptively whilst qualitative data were analyzed using content and thematic analyses.

Results

Between October 2023 and April 2024, 657 participants were enrolled and offered PrEP choice. Most (72.1%, n = 474) participants were between 18 and 24 years old and accessed services at education and training institutions (52.1%, n = 342). Furthermore, 68.8% (n = 451) chose oral PrEP at enrollment, 26.6% (n = 175) chose the PrEP ring, and 3.2% (n = 20) selected no method. Most participants accessed services through a mobile truck (n = 365, 55.6%). There was a strong preference for nurse insertion of the ring on site (n = 103, 58.9%). Site setup, privacy, and access to running water, in alignment with national PrEP ring guidelines, were reported as barriers to implementation.

Conclusion

As one of the first studies to implement community-based services for PrEP choice, the early results indicate the feasibility of delivering this service with moderate uptake of PrEP by AGYW. Understanding the service delivery conditions required to offer informed choice is important for supporting national scale-up.

Preferences for Delivery of HIV Prevention Services Among Healthcare Users in South Africa: A Discrete Choice Experiment

Progress has been made to scale oral pre-exposure prophylaxis (PrEP) as part of combination HIV prevention, with the WHO recommending differentiated, simplified and demedicalized approaches. This study explored user preferences for components of a PrEP service delivery package, through a discrete choice experiment (DCE) among 307 people accessing primary healthcare services in South Africa between November 2022 and February 2023. Attributes included were: Source of information about HIV prevention and PrEP; Site for PrEP initiation and follow-up; Frequency of follow-up; PrEP pick-up point; HIV testing whilst using PrEP; Contact between appointments. A D-efficient DCE design was created with 16 choice sets in 2 blocks. DCE data were analysed using generalised multinomial logistic models. Compared to printed materials, participants preferred getting information about PrEP online (aOR = 7.73, 95% CI = 5.13-11.66) and through WhatsApp (aOR = 2.23, 95% CI = 0.98-5.55). PrEP initiation at a pharmacy or mobile clinic was valued equally to initiating PrEP at a clinic, but a community pop-up site was less preferred (aOR = 0.46, 95% CI = 0.33-0.64). There was a preference for 6-monthly over 3-monthly follow-up (aOR = 11.88, 95% CI = 5.44-25.94). Participants preferred collecting PrEP from a pharmacy (aOR = 5.02, 95% CI = 3.45-7.31), through home delivery (aOR = 2.18, 95% CI = 1.26-3.78) and from a vending machine (aOR = 1.43, 95% CI = 1.02-1.99) relative to where they initiated PrEP. Participants also preferred HIV self-testing over a healthcare provider test (aOR = 5.57, 95% CI = 3.72, 8.36). WhatsApp or Facebook groups (aOR = 4.12, 95% CI = 3.00-5.67), monthly phone calls (aOR = 2.84, 95% CI = 1.73-4.67) and weekly messages (aOR = 1.47, 95% CI = 1.10-1.97) were preferred contact between appointments, relative to no contact. To meet users' preferences, there is a need to expand decentralised and self-led HIV prevention services.

Barriers to PrEP use and adherence among adolescent girls and young women in Eastern, Southern, and Western Africa: a scoping review

BACKGROUND

Adolescent girls and young women (AGYW) are disproportionately affected by HIV. Globally, in 2022, an estimated 4000 AGYW 15-24 were newly infected with HIV weekly, and nearly 78% of these infections occurred in sub-Saharan Africa. Oral Pre-Exposure Prophylaxis (PrEP) is a key HIV prevention option within an overall HIV combination prevention approach with an efficacy of over 90% when taken correctly. However, uptake of and adherence to PrEP remains low, particularly among AGYW. This scoping review aims to map available evidence on factors that limit PrEP use among AGYW in Eastern, Southern, and Western African countries to inform research, policy, and practice on delivery of PrEP. Our review identified factors that affect PrEP journey among AGYW along the HIV prevention cascade.

METHODS

Guided by Arksey and O'Malley framework and using the PRISMA extension for scoping reviews, we searched the Web of Science, Global Health, and PubMed databases. Our review focused on oral PrEP, specifically papers reporting on barriers to PrEP experienced by AGYW, and peer-reviewed English-language articles published between 2012 and 2023.

RESULTS

Of 1063 papers screened, 25 were included. Over half (60%) of the studies were qualitative; 72% were conducted in Kenya and South Africa. The barriers affecting motivation were, fear of side effects and pill burden, percieved low HIV risk, perceived stigma, PrEP use disapproval from parents and partners. PrEP access was limited by healthcare providers' stigma, isolated clinic setup, and lack of resources. Effective PrEP use was limited by a lack of parental or partner support, stigma, and lifestyle changes.

CONCLUSIONS

Adolescent girls and young women face multiple and often intersecting barriers to effective PrEP use with stigma being a factor cross-cutting all steps of the prevention cascade. Similarly, lack of social support, reflected through disapproval and judgmental attitudes and low HIV risk perception, also affected two steps of the prevention cascade. Our review identified gaps in available evidence, with most studies conducted in only two countries and few quantitative studies available. Improving PrEP uptake and adherence requires interventions that address barriers across the cascade, with a particular focus on stigma and social support.

Improving HIV testing, linkage, and retention in care among South African men through U = U messaging: A study protocol for two sequential hybrid type 1 effectiveness-implementation randomized controlled trials

BACKGROUND

Increasing HIV testing and treatment coverage among people living with HIV (PLHIV) is essential for achieving global HIV epidemic control. However, compared to women, cis-gender heterosexual men living with HIV are significantly less likely to know their HIV status, initiate anti-retroviral therapy (ART) and achieve viral suppression. This is particularly true in South Africa, where men are also at increased risk of mortality resulting from AIDS-related illnesses. While there is growing knowledge of Treatment as Prevention or the concept Undetectable = Untransmittable (U = U) among PLHIV in Western and high-income countries, the reach and penetration of the U = U message in sub-Saharan Africa remains limited, and few studies have evaluated the impact of accessible and relatable U = U messages on ART initiation and adherence. To address these gaps, rigorous evaluations of interventions that incorporate U = U messages are needed, especially among men in high prevalence settings.

METHODS

Building on our U = U messages that we previously developed for men using behavioral economics insights and a human-centered design, we will conduct two sequential hybrid type 1 effectiveness-implementation trials to evaluate the impact of U = U messages on men's uptake of community-based HIV testing and ART initiation (Trial 1), and retention in care and achievement of viral suppression (Trial 2). For trial 1, a cluster randomized trial will be implemented with HIV testing service site-days (each day at one testing site) randomized to U = U or standard-of-care (SoC) messages inviting men to test for HIV. For trial 2, an individual-level randomized control trial will be implemented, with men initiating ART at six government clinics randomized to receive U = U counselling or SoC treatment adherence messaging. We will incorporate a multi-method evaluation to inform future implementation of U = U messaging interventions. The study will be conducted in the Buffalo City Metro Health District of the Eastern Cape Province and in the Cape Town Metro Health District in the Western Cape Province in South Africa.

DISCUSSION

These trials are the first to rigorously evaluate the impact of U = U messaging on HIV testing uptake, ART initiation and achievement of viral suppression among African men. If effective, these messaging interventions can shape global HIV testing, treatment and adherence counselling guidelines and practices.

Enhanced Oral Pre-exposure Prophylaxis (PrEP) Implementation for Ugandan Fisherfolk: Pilot Intervention Outcomes

Mobile populations such as fisherfolk show high HIV incidence and prevalence. We pilot-tested implementation strategies to enhance pre-exposure prophylaxis (PrEP) uptake and adherence in the context of healthcare outreach events in two mainland fisherfolk communities on Lake Victoria, Uganda from September 2021 to February 2022. The implementation strategies included PrEP adherence supporters (selected from PrEP users' social networks), community workshops (to address misconceptions and stigma, and empower PrEP advocacy), and check-in calls (including refill reminders). PrEP medical records data were collected from 6-months pre-intervention to 6-months post-intervention. Qualitative interviews with 20 PrEP users (10 who continued, 10 who discontinued), 9 adherence supporters, and 7 key partners (providers, community leaders) explored acceptability. Percentages of PrEP initiators (of those eligible) were significantly higher during the intervention (96.5%) than 6-months before the intervention (84.5%), p < 0.0001; percentages of PrEP users who persisted (i.e., possessed a refill) 6-months post-initiation (47.9% vs. 6.7%) and had at least 80% PrEP coverage (based on their medication possession ratio) from the initiation date to 6-months later (35.9% vs. 0%) were higher during versus pre-intervention, p < 0.0001. A comparison fisherfolk community with better healthcare access had lower uptake (78.3%; p < 0.0001) and persistence at 6-months (34.0%; p < 0.001), but higher coverage during the intervention period (70.4%; p < 0.0001). Qualitative data suggested the strategies promoted PrEP use through reduced stigma and misconceptions. The intervention bundle cost was $223.95, $172.98, and $94.66 for each additional person for PrEP initiation, persistence, and coverage, respectively. Enhanced community-based PrEP implementation that fosters a supportive community environment can improve PrEP use in mobile populations without easy access to healthcare. (NCT05084716).

Sexually Transmitted Infection Prevalence, Partner Notification, and Human Immunodeficiency Virus Risk Perception in a Cohort of Women Completing Sexually Transmitted Infection Screening as Part of a Safer Conception Study

BACKGROUND

Integrating sexually transmitted infection (STI) and preexposure prophylaxis (PrEP) care may optimize sexual and reproductive health.

METHODS

We nested an STI substudy within a human immunodeficiency virus (HIV) prevention cohort (parent study) of 18- to 35-year-old women from South Africa, planning pregnancy with a partner with HIV or of unknown serostatus. Parent-study women completed annual surveys regarding HIV-risk perceptions and were offered oral PrEP. Preexposure prophylaxis initiators completed quarterly plasma tenofovir (TFV) testing. Substudy women completed STI screening at enrollment, 6 months, onset of pregnancy, and in the third trimester via examination, vaginal swabs tested via PCR for Chlamydia trachomatis , Neisseria gonorrhoeae , Trichomonas vaginalis , Mycoplasma genitalium , and blood tested for Treponema pallidum . Follow-up was 6 months. Women with STIs were treated, offered partner notification (PN) cards, and surveyed regarding PN practices. We describe STI prevalence and incidence, and model factors associated with prevalent infection. Sexually transmitted infection substudy and parent study-only participants were matched on age and number of days on study to assess HIV-risk perception scores between the 2 groups and the proportion with detectable TFV.

RESULTS

Among 50 substudy participants, 15 (30%) had prevalent STI. All 13 completing follow-up reported PN. Most did not prefer assisted PN. Mean HIV risk perception scores and proportion with detected plasma TFV were similar across groups.

CONCLUSIONS

High STI prevalence supports the importance of laboratory screening to optimize sexual health for women planning pregnancy. Rates of self-reported PN are reassuring; low interest in assisted PN suggests the need for alternative approaches. Enhanced STI care did not affect HIV-risk perception or PrEP adherence, however both were relatively high in this cohort.

High study participation but diverging adherence levels: qualitatively unpacking PrEP use among adolescent girls and young women over two years in Eastern Cape, South Africa

In Southern and Eastern Africa, initiation of daily oral pre-exposure prophylaxis (PrEP) for HIV prevention has been high among adolescent girls and young women (AGYW) offered PrEP. However, persistence and prevention-effective use of PrEP among this critical group continues to be a challenge. We conducted a qualitative sub-study of AGYW from the Community PrEP Study in Eastern Cape Province, South Africa who had high rates of pick up for monthly PrEP refills over two years, but differing levels of PrEP adherence based on tenofovir-diphosphate (TFV-DP) measurements in dried blood spots (DBS). Contrasting 22 AGYW with low versus high levels of TFV-DP in DBS, we qualitatively explored factors which influenced PrEP persistence vs. non-persistence, unique patterns of PrEP use (e.g., discarding or stockpiling), and participant recommendations for improving AGYW prevention-effective use of PrEP in the future. Results showed that PrEP misconceptions and mistrust among participants' social networks negatively influenced adherence. In comparison, supportive families and/or partners and personal trust that PrEP works positively influenced adherence. Those with low adherence described being motivated to come to the site for other study benefits (e.g., reimbursement money, snacks, sanitary pads) and discarding PrEP to avoid stigma associated with being seen with pills. Future PrEP implementation strategies should focus on involving families and partners in PrEP support for AGYW and minimizing PrEP stigma at a community level.Trial registration NCT03977181.

HIV epidemiology, prevention, treatment, and implementation strategies for public health

The global HIV response has made tremendous progress but is entering a new phase with additional challenges. Scientific innovations have led to multiple safe, effective, and durable options for treatment and prevention, and long-acting formulations for 2-monthly and 6-monthly dosing are becoming available with even longer dosing intervals possible on the horizon. The scientific agenda for HIV cure and remission strategies is moving forward but faces uncertain thresholds for success and acceptability. Nonetheless, innovations in prevention and treatment have often failed to reach large segments of the global population (eg, key and marginalised populations), and these major disparities in access and uptake at multiple levels have caused progress to fall short of their potential to affect public health. Moving forward, sharper epidemiologic tools based on longitudinal, person-centred data are needed to more accurately characterise remaining gaps and guide continued progress against the HIV epidemic. We should also increase prioritisation of strategies that address socio-behavioural challenges and can lead to effective and equitable implementation of existing interventions with high levels of quality that better match individual needs. We review HIV epidemiologic trends; advances in HIV prevention, treatment, and care delivery; and discuss emerging challenges for ending the HIV epidemic over the next decade that are relevant for general practitioners and others involved in HIV care.

Creating allies: qualitative exploration of young women's preferences for PrEP methods and parents' role in PrEP uptake and user support in urban and rural Zambia

BACKGROUND

Zambian adolescent girls and young women (AGYW) have high HIV incidence and face barriers to the use of pre-exposure prophylaxis (PrEP). Parental support improves PrEP use and adherence in some settings, but negative parental attitudes toward HIV prevention may inhibit engagement with AGYW. We explored perceptions of future PrEP methods among AGYW and parents and parent-youth engagement on HIV prevention and PrEP use.

METHODS

We conducted a qualitative descriptive study among AGYW and parents of AGYW in five provinces in Zambia in September-October 2021. We conducted 10 focus group discussions (FGDs) and four in-depth interviews (IDIs) with AGYW participants (n = 87) and seven FGDs and four IDIs among parents of AGYW (n = 62). All FGDs and IDIs were audio-recorded, transcribed verbatim, and analyzed to identify qualitative themes.

RESULTS

Most AGYW participants preferred the discreet nature and longer duration of injectable PrEP compared to the PrEP ring and oral PrEP. Many AGYWs reported inability to disclose PrEP use to their parents due to lack of parental support based on cultural taboos against premarital sex. Nevertheless, AGYW participants said they would like to talk to their parents about PrEP so their parents could support their use. Many parents also described difficulties discussing PrEP with their daughters because of cultural and religious beliefs about abstinence from sex before marriage. However, parents acknowledged that the threat of HIV is real and said they need PrEP knowledge and guidance on speaking with their children about HIV prevention and PrEP.

CONCLUSIONS

Although many parents are currently not playing a role in daughters' decisions about PrEP use, both parents and AGYW are willing to engage with each other on HIV prevention issues. To foster parent-child engagement, HIV prevention programs should not only provide information about PrEP but also address social norms that impede discussion of HIV prevention and equip both parents and AGYW with skills and support for such conversations. Community sensitization is also needed as new PrEP products are introduced, to create an enabling environment for parent-child engagement by increasing awareness, countering misconceptions, and reducing stigma.

Youth-friendly services was the magic: Experiences of adolescent girls and young women in the community PrEP study, South Africa

Adherence to daily oral pre-exposure prophylaxis (PrEP) for HIV prevention has been challenging for adolescent girls and young women (AGYW). As part of The Community PrEP Study (CPS), AGYW were randomised to HIV-prevention empowerment counselling (intervention) or basic medication pick-up (control). In this qualitative sub-study, we interviewed AGYW participants (n = 39) to explore PrEP use and study experiences by study arm, and study staff (n = 7) to explore study implementation, site environment, and participant engagement. Data were thematically analysed using a constant comparison approach. Comparative matrices assessed similarities and differences in study experiences and PrEP support preferences. Friendly, non-judgmental, non-stigmatizing study staff were described as central to participant's positive experiences. Participants highly valued CPS staff's holistic health support (e.g. physical and psycho-social). Intervention participants described empowerment counselling as helpful in supporting PrEP disclosure. However, control participants also described disclosing PrEP use to trusted individuals. Participants and staff recommended public-sector PrEP services provide holistic, confidential, and integrated sexual and reproductive health services, and community sensitisation. An adolescent and youth-friendly environment was the primary factor motivating AGYW's study engagement. While HIV-prevention empowerment counselling was well received, welcoming, respectful and non-judgmental staff may be the 'secret sauce' for implementing effective PrEP services to AGYW.

Experience with Contraceptive Dosage Forms and Interest in Novel PrEP Technologies in Women

New pre-exposure prophylaxis (PrEP) strategies tailored to the needs and expectations of individuals at risk of HIV acquisition are needed. In the CAPRISA 082 prospective cohort study in KwaZulu-Natal, South Africa, sexually active women aged 18 to 30 reported, through interviewer-administered questionnaires, on their prior contraceptive experience and interest in both approved and potential future PrEP dosage forms (oral PrEP, long-acting injectable PrEP, and PrEP implants) between March 2016 and February 2018. Univariable and multivariable Poisson regression models with robust standard errors were used to detect associations between women's prior and current contraceptive use and interest in PrEP options. Of 425 women enrolled, 381 (89.6%) had used at least one modern female contraceptive method previously, with injectable depot medroxyprogesterone acetate (DMPA) being used by 79.8% (n = 339). Women were more likely to show interest in a future PrEP implant if they were currently using (aRR 2.1, CI 1.43-3.07, p = 0.0001) or had ever used (aRR 1.65, CI 1.14-2.40, p = 0.0087) a contraceptive implant, and were more likely to choose an implant as their first choice method than the implant-naïve (current users aRR 3.2, CI 1.79-5.73, p < 0.0001; "ever" users aRR 2.12, CI 1.16-3.86, p = 0.0142). Women were more interested in injectable PrEP if they had used injectable contraceptives (current users aRR 1.24, CI 1.06-1.46, p = 0.0088; "ever" users aRR 1.72, CI 1.20-2.48, p = 0.0033); and were more interested in oral PrEP if they had ever used oral contraceptives (aRR 1.3, CI 1.06-1.59, p = 0.0114). This apparent relationship between women's contraceptive experience and their interest in novel forms of PrEP in an equivalent dosage form may play a future role in strengthening HIV prevention efforts in women at high risk of HIV acquisition.

Developing the Speaking Out and Allying Relationships Intervention on Videoconference for HIV-Positive GBMSM in Eastern Cape, South Africa

In South Africa, HIV prevalence for gay, bisexual, and men who have sex with men (GBMSM) is as high as 49.5%, yet only 25.7% are taking treatment, resulting in transmission risk between partners and the need for dyadic interventions for men in relationships. Through our preliminary research, we identified the evidence-based intervention Healthy Relationships (HR)-an HIV risk assessment and status disclosure intervention for those in relationships-to be tailored into videoconference format for partnered HIV-positive GBMSM in South Africa. The HR adaptation, called SOAR (Speaking Out & Allying Relationships), applied a human-centered design approach. In-depth interviews were conducted with HIV-positive GBMSM (N = 15) to refine intervention preferences with results used to establish a beta SOAR. A trained interventionist conducted SOAR functionality (n = 6) and usability (n = 7) tests with separate invited groups composed of the original participants interviewed. Field logs, focus group discussions, and a study-specific preference survey were administered. Thematic analysis and descriptive statistics were completed with a convergent analytical approach used to understand usability. Overall experience of GBMSM in SOAR was good (69%) or excellent (31%). More than half of the participants (61%) rated using videoconferencing for SOAR as good, with 38% rating it as fair. All participants stated that SOAR was understandable and satisfactory with willingness to recommend it to other GBMSM. This adaptation approach was effective, and the resultant SOAR intervention has the potential to improve individual coping and HIV communication skills with partners to engage with biomedical prevention and in turn support GBMSM couples.

Factors that influence adolescent girls and young women's re-initiation or complete discontinuation from daily oral PrEP use: a qualitative study from Eastern Cape Province, South Africa

INTRODUCTION

Adolescent girls and young women (AGYW) face barriers that jeopardize their prevention-effective use of daily oral pre-exposure prophylaxis (PrEP). We sought to understand factors that influence AGYW's prolonged breaks in PrEP use, and their decisions to re-initiate or discontinue using PrEP in the context of a community-based adherence support intervention.

METHODS

In-depth interviews (IDIs) were conducted between December 2019 and April 2021 with purposively selected AGYW (aged 16-25) enrolled in the Community PrEP Study (CPS) in Buffalo City Metro Health District, Eastern Cape Province, South Africa. AGYW were offered monthly PrEP for 24 months at two community-based study sites. Interview guides were informed by the Information-Motivation-Behavioural Skills Model, and data were analysed using illustrative code reports and a case analysis.

RESULTS

A total of 603 participants were enrolled and initiated on PrEP in the parent study. Fifty-three IDIs were conducted with 50 CPS participants. Findings revealed that external factors (e.g. local movement, school holidays and medication side-effects) and social conflicts (e.g. discretion and partner mistrust) directly influenced breaks in PrEP usage. A decrease in one's self-perception of HIV risk prolonged the duration of these "PrEP breaks." Once PrEP refill visits were missed, some AGYW delayed returning for refills out of fear of being scolded by study staff. The differences between those participants who eventually re-initiated PrEP and those who disengaged from PrEP use can be attributed to social support and encouragement, level of familiarity with PrEP, risk perceptions, self-initiated discussions with staff and diminishing side effects.

CONCLUSIONS

Despite implementing a community-based PrEP delivery platform and behavioural intervention that included support for daily oral PrEP adherence and disclosure, participants struggled with consistent daily oral PrEP use. Unpredictable life events, including local movement and schooling schedules, in addition to being judged for their perceived behaviours, pose a challenge for consistent pill pick-up for AGYW and habit formation. Long-acting injectable PrEP may mitigate a number of these external barriers. Interventions that integrate long-term planning skills, how to navigate existing social judgements and how to access sources of social support may further improve habit formation for PrEP use, regardless of its formulation.

Uptake of a patient-centred dynamic choice model for HIV prevention in rural Kenya and Uganda: SEARCH SAPPHIRE study

INTRODUCTION

Person-centred HIV prevention delivery models that offer structured choices in product, testing and visit location may increase coverage. However, data are lacking on the actual uptake of choices among persons at risk of HIV in southern Africa. In an ongoing randomized study (SEARCH; NCT04810650) in rural East Africa, we evaluated the uptake of choices made when offered in a person-centred, dynamic choice model for HIV prevention.

METHODS

Using the PRECEDE framework, we developed a persont-centred, Dynamic Choice HIV Prevention (DCP) intervention for persons at risk of HIV in three settings in rural Kenya and Uganda: antenatal clinic (ANC), outpatient department (OPD) and in the community. Components include: provider training on product choice (predisposing); flexibility and responsiveness to client desires and choices (pre-exposure prophylaxis [PrEP]/post-exposure prophylaxis [PEP], clinic vs. off-site visits and self- or clinician-based HIV testing) (enabling); and client and staff feedback (reinforcing). All clients received a structured assessment of barriers with personalized plans to address them, mobile phone access to clinicians (24 hours/7 days/week) and integrated reproductive health services. In this interim analysis, we describe the uptake of choices of product, location and testing during the first 24 weeks of follow-up (April 2021-March 2022).

RESULTS

A total of 612 (203 ANC, 197 OPD and 212 community) participants were randomized to the person-centred DCP intervention. We delivered the DCP intervention in all three settings with diverse populations: ANC: 39% pregnant; median age: 24 years; OPD: 39% male, median age 27 years; and community: 42% male, median age: 29 years. Baseline choice of PrEP was highest in ANC (98%) vs. OPD (84%) and community (40%); whereas the proportion of adults selecting PEP was higher in the community (46%) vs. OPD (8%) and ANC (1%). Personal preference for off-site visits increased over time (65% at week 24 vs. 35% at baseline). Interest in alternative HIV testing modalities grew over time (38% baseline self-testing vs. 58% at week 24).

CONCLUSIONS

A person-centred model incorporating structured choice in biomedical prevention and care delivery options in settings with demographically diverse groups, in rural Kenya and Uganda, was responsive to varying personal preferences over time in HIV prevention programmes.

Integration of sexually transmitted infection and HIV pre-exposure prophylaxis services in sub-Saharan Africa: a scoping review

Background

Persons living in sub-Saharan Africa (SSA) face disproportionate risk from overlapping epidemics of HIV and bacterial sexually transmitted infections (STIs). Pre-exposure prophylaxis (PrEP) for prevention is gradually being scaled up globally including in several settings in SSA, which represents a key opportunity to integrate STI services with HIV pre-exposure prophylaxis (PrEP). However, there is limited literature on how to successfully integrate these services, particularly in the SSA context. Prior studies and reviews on STI and PrEP services have largely focused on high income countries.

Methods

We conducted a scoping review of prior studies of integration of STI and PrEP services in SSA. We searched PubMed, EMBASE, Cochrane, and CINAHL, in addition to grey literature to identify studies that were published between January 2012 and December 2022, and which provided STI and PrEP services in SSA, with or without outcomes reported. Citations and abstracts were reviewed by two reviewers for inclusion. Full texts were then retrieved and reviewed in full by two reviewers.

Results

Our search strategy yielded 1951 records, of which 250 were retrieved in full. Our final review included 61 reports of 45 studies. Most studies were conducted in Southern (49.2%) and Eastern (24.6%) Africa. Service settings included public health clinics (26.2%), study clinics (23.0%), sexual and reproductive care settings (23.0%), maternal and child health settings (8.2%), community based services (11.5%), and mobile clinics (3.3%). A minority (11.4%) of the studies described only syndromic STI management while most (88.6%) included some form of etiological laboratory STI diagnosis. STI testing frequency ranged from baseline testing only to monthly screening. Types of STI tested for was also variable. Few studies reported outcomes related to implementation of STI services. There were high rates of curable STIs detected by laboratory testing (baseline genitourinary STI rates ranged from 5.6-30.8% for CT, 0.0-11.2% for GC, and 0.4-8.0% for TV).

Discussion

Existing studies have implemented a varied range of STI services along with PrEP. This range reflects the lack of specific guidance regarding STI services within PrEP programs. However, there was limited evidence regarding implementation strategies for integration of STI and PrEP services in real world settings.

What motivated men to start PrEP? A cross-section of men starting PrEP in Buffalo city municipality, South Africa

BACKGROUND

Compared to women, South African men are less likely to know their HIV status (78% vs. 89%), have suppressed viral loads (82% vs. 90%), or access HIV prevention services. To achieve epidemic control where heterosexual sexual behavior drives transmission, interventions to improve the uptake of HIV testing services (HTS) and prevention services must also target cis-gendered, heterosexual men. There is limited understanding of these men's needs and wants with regards to accessing pre-exposure prophylaxis (PrEP).

METHODS

Adult men (≥ 18 years) from a peri-urban community in Buffalo City Municipality were offered community-based HTS. Those who received a negative HIV test result were offered community-based, same-day oral PrEP initiation. Men initiating PrEP were invited to participate in a study exploring men's HIV prevention needs and reasons for initiating PrEP. An in-depth interview guide, developed using the Network-Individual-Resources model (NIRM), explored men's perceived HIV acquisition risk, prevention needs, and preferences for PrEP initiation. Interviews were conducted by a trained interviewer in isiXhosa or English, audio-recorded and transcribed. Thematic analysis was used, guided by the NIRM to generate findings.

RESULTS

Twenty-two men (age range 18-57 years) initiated PrEP and consented to study participation. Men reported elevated HIV acquisition risk associated with alcohol use and condom-less sex with multiple partners as facilitators driving PrEP initiation. They anticipated social support from family members, their main sexual partner and close friends for their PrEP use, and discussed other men as important sources of support for PrEP initiation. Nearly all men expressed positive views of people using PrEP. Participants believed HIV testing would be a barrier for men interested in accessing PrEP. Men recommended that access to PrEP be convenient, rapid, and community-based (i.e., not clinic-based).

DISCUSSION

Self-perceived risk for HIV acquisition was a major facilitator for men's PrEP initiation. Although men expressed positive perceptions of PrEP users, they noted that HIV testing may be a barrier to PrEP initiation. Finally, men recommended convenient access points to facilitate PrEP initiation and sustained use. Gender-responsive interventions tailored to men's needs, wants, and voices will facilitate their uptake of HIV prevention services, and help to end the HIV epidemic.

"I know why I am taking this pill": Young women navigation of disclosure and support for PrEP uptake and adherence in Eastern Cape Province, South Africa

There is limited understanding of the dynamic interplay between adolescent girl's and young women's (AGYW) disclosure and social support for using oral pre-exposure prophylaxis (PrEP) and adherence. Towards this, we conducted interviews with 42 AGYW enrolled in The Community PrEP Study who exhibited either high or low blood concentrations of tenofovir-diphosphate (TFV-DP) in dried blood spots. Guided by Theories of Practice, interviews and analysis focused on AGYW perspectives and experiences with PrEP disclosure, support and adherence. AGYW with high TFV-DP blood concentrations described larger social support networks and disclosure events. In contrast, those with low TFV-DP blood concentrations described disclosing to fewer people, resulting in limited social support. Participants discussed partner support, however, this support was not described as consequential to adherence, irrespective of TFV-DP levels. Those with high levels of TFV-DP in their blood described the ability to navigate social scrutiny and changes in social support, while those with low levels of TFV-DP in their blood were more likely to question their own continued use of PrEP. To facilitate AGYW's prevention-effective use of PrEP, expanded skill-building for disclosure and resiliency against changes to social support should be examined as part of PrEP services.
