Abstract
We evaluated correlates of adherence to PrEP, including daily oral tenofovir disoproxil fumarate in combination emtricitabine (oral FTC/TDF) and the monthly dapivirine ring (ring)among adolescent girls and young women (AGYW) in the MTN-034/REACH study. We enrolled 247 AGYW aged 16-21 years in South Africa, Uganda and Zimbabwe (ClinicalTrials.gov: NCT03074786). Participants were randomized to the order of oral FTC/TDF or ring use for 6 months each in a crossover period, followed by a 6-month choice period. We assessed potential adherence correlates-individual, interpersonal, community, study, and product-related factors-quarterly via self-report. We measured biomarkers of adherence monthly; high adherence was defined as > 4 mg dapivirine released from returned rings or intracellular tenofovir diphosphate levels ≥ 700 fmol/punch from dried blood spots (DBS). We tested associations between correlates and objective measures of high adherence using generalized estimating equations. High adherence to oral FTC/TDF was significantly associated with having an older primary partner (p = 0.04), not having exchanged sex in the past 3 months (p = 0.02), and rating oral FTC/TDF as highly acceptable (p = 0.003). High ring adherence was significantly associated with unstable housing (p = 0.01), disclosing ring use to a male family member (p = 0.01), and noting a social benefit from study participation (p = 0.03). All associations were moderate, corresponding to about 6%-10% difference in the proportion with high adherence. In our multinational study, correlates of adherence among African AGYW differed for oral FTC/TDF and the ring, highlighting the benefit of offering multiple PrEP options.

Lessons learnt from daily oral PrEP delivery to inform national planning for PrEP ring introduction for women in low-income and middle-income countries: a qualitative inquiry of international stakeholders. BMJ Glob Health 2024; 9:e014709.

Abstract
INTRODUCTION Some African countries plan to introduce and scale-up new long-acting pre-exposure prophylaxis methods (LA-PrEP), like the monthly dapivirine vaginal ring (PrEP ring) and injectable cabotegravir. National costed implementation plans, roadmaps for successful product implementation, are often overlooked. International stakeholders engaged in oral PrEP planning, introduction and scale-up are an information resource of lessons learned to advise LA-PrEP planning. We consulted such international stakeholders and synthesised oral PrEP lessons to inform the development of a costed rollout plan template for LA-PrEP. METHODS From selected global health organisations (five international nongovernmental, four donor, four university/research and two multilateral), we interviewed 27 representatives based in America, Europe, Asia and Africa about strategic content and approaches for LA-PrEP policy, programming and implementation. We conducted a thematic analysis of the interview data for implementation considerations. RESULTS From the consultations, we identified six implementation themes for LA-PrEP introduction and scale-up: (1) ethically increasing choice and avoiding coercion; (2) de-stigmatising PrEP by focusing on preference rather than risk-based eligibility; (3) integrating LA-PrEP into services that are more woman-oriented, couple-oriented and family-oriented, and providing private spaces for LA-PrEP delivery; (4) de-medicalising delivery of relatively safe products (eg, PrEP ring); (5) constructing multilevel, nuanced communication strategies to address measured and perceived product efficacy and effectiveness; and (6) devising product-agnostic, modular approaches to service delivery. Despite the widespread emphasis on integration, few stakeholders offered empirical examples of successful integration approaches and frameworks. CONCLUSIONS Lessons learnt from stakeholder participants suggest standardised and modular processes can improve efficiencies in LA-PrEP planning and implementation. Tiered communication strategies addressing product efficacy and effectiveness will improve clients' and providers' efficacy in making informed decisions. Integration is important for LA-PrEP delivery, but data on empirical integration approaches and frameworks is minimal: further research in this discipline is needed.

Abstract
To develop effective PrEP adherence interventions, it is important to understand the interplay between disclosure of pre-exposure prophalxis (PrEP) use, social support, and PrEP adherence. We leveraged the HPTN 082 study conducted among 451 adolescent girls and young women (AGYW) (ages 16 to 25 years, 2016 to 2019) in South Africa and Zimbabwe. Among the 349 who had month three disclosure and PrEP adherence data, 60% (n = 206) felt supported by adults, and 89% (n = 309) disclosed PrEP use to at least one person. PrEP disclosure was not associated with increased adherence, measured by intracellular tenofovir-diphosphate concentrations in dried blood spots. Women who reported having supportive adults, and disclosed to their parents, had higher adherence at 6 months with an increase of 177 fmol/punch (95% CI 12 to 343, t = 2.11, p = 0.04). PrEP interventions that help AGYW identify supportive relationships and effectively communicate the benefits of PrEP may improve PrEP adherence.Clinicaltrials.gov ID number: NCT02732730.

Abstract
Out-of-school adolescent girls/young women (AGYW) in Africa are at increased risk for HIV and are underserved by HIV prevention interventions. Identifying social networks of out-of-school AGYW may be a strategic approach for reaching them. A sequential mixed methods study design was used. The PLACE (Priorities for Local AIDS Control Efforts) methodology, implemented in one ward of Dar es Salaam, Tanzania, identified 69 networks of AGYW. We randomly selected 28 networks and conducted surveys and network assessments with 80.9% (n = 310) of the members. On average, the networks consisted of 13.7 members, and had a density of 0.65 and a transitivity of 0.80, indicating high cohesion. The networks were mostly female (92%). On average, 67% of network membership were AGYW aged 15-24 years, of whom 70% were out-of-school and 67% were sexually active. Among sexually active AGYW aged 15-24, self-reported HIV seropositivity was 12.2%. We then conducted focus group discussions with 6 purposively selected networks. AGYW described their networks as sources of support and advice. Social norms supported AGYW engaging in transactional sex to alleviate life's hardships; it was the easiest way to earn income without "sweating". AGYW discussed IPV as a common experience, and social norms stigmatized AGYWs' use of condoms. AGYW were largely unaware of pre-exposure prophylaxis. The self-reported HIV prevalence rates of this cohort were higher than national averages, suggesting we tapped into high-risk networks. Social norms promoted transactional and unprotected sex. Social networks are an acceptable channel for HIV prevention intervention delivery to out-of-school AGYW.

Abstract
PURPOSE OF REVIEW Despite highly effective biomedical HIV pre-exposure prophylaxis (PrEP) options, suboptimal PrEP uptake impedes progress towards ending the epidemic in the United States of America (USA). Implementation science bridges what we know works in controlled clinical trial settings to the context and environment in which efficacious tools are intended to be deployed. In this review, we focus on strategies that target PrEP use barriers at the system or structural level, exploring the implications and opportunities in the context of the fragmented USA healthcare system. RECENT FINDINGS Task shifting could increase PrEP prescribers, but effectiveness evidence is scarce in the USA, and generally focused in urban settings. Integration of PrEP within existing healthcare infrastructure concentrates related resources, but demonstration projects rarely present the resource implications of redirecting staff. Changing the site of service via expanded telehealth could improve access to more rural populations, though internet connectivity, technology access, and challenges associated with determining biomedical eligibility remain logistical barriers for some of the highest burden communities in the USA. Finally, a tailored care navigation and coordination approach has emerged as a highly effective component of PrEP service provision, attempting to directly modify the system-level determinants of PrEP use experienced by the individual. We highlight recent advances and evidence surrounding task shifting, integration, service delivery, and tailoring. With the exception of tailored care navigation, evidence is mixed, and the downstream impact and sustainability of task shifting and care integration require further attention. To maximize PrEP outcomes, research will need to continue to examine the interplay between individuals, clinics, and the healthcare system and associated policies within which they operate.

Abstract
INTRODUCTION Oral pre-exposure prophylaxis (PrEP) has the potential to reduce HIV acquisition among adolescent girls and young women (AGYW) in sub-Saharan Africa, a priority population for epidemic control. However, intimate partner violence (IPV) and low relationship power can create significant challenges to PrEP use. The Tu'Washindi intervention aimed to increase PrEP use by addressing relationship- and violence-related barriers among AGYW enrolled in the DREAMS Initiative in Siaya County, Kenya. METHODS Our multi-level, community-based intervention was piloted in a cluster-randomized controlled trial conducted at six DREAMS sites from April to December 2019 (NCT03938818). Three intervention components were delivered over 6 months: an eight-session empowerment-based support club, community sensitization targeted towards male partners and a couples' PrEP education event. Participants were ages 17-24, HIV negative and either eligible for, or already taking, PrEP. Over 6 months of follow-up, we assessed IPV (months 3 and 6) and PrEP uptake and continuation (month 6) through interviewer-administered questionnaires; PrEP adherence was assessed with Wisepill electronic monitoring devices. These outcomes were compared using adjusted Poisson and negative binomial regression models. RESULTS We enrolled 103 AGYW with median age of 22 years (IQR 20-23); one-third were currently taking PrEP and 45% reported IPV in the past 3 months. Retention was 97% at month 6. Compared to the control arm, intervention arm participants were more likely to initiate PrEP, if not already using it at enrolment (52% vs. 24%, aRR 2.28, 95% CI 1.19-4.38, p = 0.01), and those taking PrEP had more days with device openings (25% of days vs. 13%, aRR 1.94, 95% CI 1.16-3.25, p = 0.01). Twenty percent of participants reported IPV during follow-up. There were trends towards fewer IPV events (aIRR 0.66, 95% CI 0.27-1.62, p = 0.37) and fewer events resulting in injury (aIRR 0.21, 95% CI 0.04-1.02, p = 0.05) in the intervention versus control arm. CONCLUSIONS Tu'Washindi shows promise in promoting PrEP uptake and adherence among AGYW without concomitant increases in IPV; however, adherence was still suboptimal. Further research is needed to determine whether these gains translate to increases in the proportion of AGYW with protective levels of PrEP adherence and to evaluate the potential for the intervention to reduce IPV risk.

Early implementation learnings on acceptability and feasibility of "V": a multi-level PrEP intervention designed with and for adolescent girls and young women in Zimbabwe.

Abstract
INTRODUCTION Adolescent girls and young women (AGYW) remain disproportionately affected by HIV in Zimbabwe. Several HIV prevention options are available, including oral tenofovir-based pre-exposure prophylaxis (PrEP), however AGYW face unique barriers to PrEP uptake and continuation and novel approaches are therefore needed to empower AGYW to use PrEP. The objective of this study was to characterize early learnings from implementing a multi-level intervention consisting of fashionable branding (including a "V Starter Kit"), service integration, and peer education and support throughout a young woman's journey using oral PrEP across four phases of implementation, from creating demand, preparing for PrEP, initiation of PrEP, and adherence to PrEP. METHODS A mixed methods implementation research study was undertaken, including site observations and interviews to explore the acceptability of "V" and its relevance to target users, as well as the feasibility of integrating "V" with existing service delivery models. Interviews (n = 46) were conducted with healthcare workers, Brand Ambassadors, and young women purposively sampled from four implementation sites. Interview data was analyzed thematically using the framework method for qualitative data management and analysis. Project budgets and invoices were used to compile unit cost and procurement data for all "V" materials. RESULTS "V" was acceptable to providers and young women due to attractive branding coupled with factual and thought-provoking messaging, establishing "a girl code" for discussing PrEP, and addressing a gap in communications materials. "V" was also feasible to integrate into routine service provision and outreach, alongside other services targeting AGYW. Cost for the "V" branded materials ranked most essential-FAQ insert, pill case, makeup bag, reminder sticker-were $7.61 per AGYW initiated on PrEP. CONCLUSION "V" is a novel approach that is an acceptable and feasible multi-level intervention to improve PrEP access, uptake, and continuation among AGYW, which works through empowering AGYW to take control of their HIV prevention needs. In considering "V" for scale up in Zimbabwe, higher volume procurement and a customized lighter package of "V" materials, while still retaining V's core approach, should be explored.

Abstract
Adolescent girls and young women (AGYW) in sub-Saharan Africa remain at high risk for HIV, yet limited data exist on implementation of HIV pre-exposure prophylaxis (PrEP) for this group. We examined PrEP uptake among AGYW using a retrospective cohort enrolled in the Determined Resilient Empowered AIDS-free Mentored Safe (DREAMS) initiative in Zambia between October 2020 and March 2022. Consent was obtained from eligible AGYW at substantial risk for HIV, and they voluntarily participated in PrEP. Multivariable logistic regression was used to examine factors associated with PrEP refills following initiation. Of 4,162 HIV-negative AGYW, 3,233 (77%) were at substantial risk and initiated on PrEP. Overall, 68% of AGYW had at least one refill, but this differed significantly by age group and district. DREAMS was successful at reaching AGYW with PrEP services. More evidence is needed to assess reasons for discontinuation and to improve persistence for those with sustained HIV risk.

Abstract
INTRODUCTION Several low- and middle-income countries (LMICs) are preparing to introduce long-acting pre-exposure prophylaxis (LAP). Amid multiple pre-exposure prophylaxis (PrEP) options and constrained funding, decision-makers could benefit from systematic implementation planning and aligned costs. We reviewed national costed implementation plans (CIPs) to describe relevant implementation inputs and activities (domains) for informing the costed rollout of LAP. We assessed how primary costing evidence aligned with those domains. METHODS We conducted a rapid review of CIPs for oral PrEP and family planning (FP) to develop a consensus of implementation domains, and a scoping review across nine electronic databases for publications on PrEP costing in LMICs between January 2010 and June 2022. We extracted cost data and assessed alignment with the implementation domains and the Global Health Costing Consortium principles. RESULTS We identified 15 implementation domains from four national PrEP plans and FP-CIP template; only six were in all sources. We included 66 full-text manuscripts, 10 reported LAP, 13 (20%) were primary cost studies-representing seven countries, and none of the 13 included LAP. The 13 primary cost studies included PrEP commodities (n = 12), human resources (n = 11), indirect costs (n = 11), other commodities (n = 10), demand creation (n = 9) and counselling (n = 9). Few studies costed integration into non-HIV services (n = 5), above site costs (n = 3), supply chains and logistics (n = 3) or policy and planning (n = 2), and none included the costs of target setting, health information system adaptations or implementation research. Cost units and outcomes were variable (e.g. average per person-year). DISCUSSION LAP planning will require updating HIV prevention policies, technical assistance for logistical and clinical support, expanding beyond HIV platforms, setting PrEP achievement targets overall and disaggregated by method, extensive supply chain and logistics planning and support, as well as updating health information systems to monitor multiple PrEP methods with different visit schedules. The 15 implementation domains were variable in reviewed studies. PrEP primary cost and budget data are necessary for new product introduction and should match implementation plans with financing. CONCLUSIONS As PrEP services expand to include LAP, decision-makers need a framework, tools and a process to support countries in planning the systematic rollout and costing for LAP.

Feasibility and acceptability of peer-delivered HIV self-testing and PrEP for young women in Kampala, Uganda. BMC Public Health 2023; 23:1163. [PMID: 37322510 PMCID: PMC10273744 DOI: 10.1186/s12889-023-16081-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2022] [Accepted: 06/08/2023] [Indexed: 06/17/2023] Open
Abstract
BACKGROUND Adolescent girls and young women (AGYW) account for 29% of new HIV infections in Uganda despite representing just 10% of the population. Peer support improves AGYW linkage to HIV care and medication adherence. We evaluated the feasibility and acceptability of peer delivered HIV self-tests (HIVST) and oral pre-exposure prophylaxis (PrEP) to young women in Uganda. METHODS Between March and September 2021, we conducted a pilot study of 30 randomly selected young women, aged 18-24 years, who had received oral PrEP for at least three months, but had suboptimal adherence as measured by urine tenofovir testing (< 1500 ng/ml). Participants were offered daily oral PrEP and attended clinic visits three and six months after enrollment. Between clinic visits, participants were visited monthly by trained peers who delivered HIVST and PrEP. Feasibility and acceptability of peer-delivered PrEP and HIVST (intervention) were measured by comparing actual versus planned intervention delivery and product use. We conducted two focus groups with young women, and five in-depth interviews with peers and health workers to explore their experiences with intervention delivery. Qualitative data were analyzed using thematic analysis. RESULTS At baseline, all 30 enrolled young women (median age 20 years) accepted peer-delivered PrEP and HIVST. Peer delivery visit completion was 97% (29/30) and 93% (28/30) at three and six months, respectively. The proportion of participants with detectable tenofovir in urine was 93% (27/29) and 57% (16/28) at months three and six, respectively. Four broad themes emerged from the qualitative data: (1) Positive experiences of peer delivered HIVST and PrEP; (2) The motivating effect of peer support; (3) Perceptions of female controlled HIVST and PrEP; and (4) Multi-level barriers to HIVST and PrEP use. Overall, peer delivery motivated young women to use HIVST and PrEP and encouraged persistence on PrEP by providing non-judgmental client-friendly services and adherence support. CONCLUSION Peer delivery of HIVST and oral PrEP was feasible and acceptable to this sample of young women with suboptimal PrEP adherence in Uganda. Future larger controlled studies should evaluate its effectiveness among African AGWY.

Abstract
PURPOSE Women involved in the carceral system (CS) experience several conditions that increase their risk for HIV (e.g. high rates of substance use, psychiatric disorders, histories of victimization). The purpose of this study is to explore perspectives on potential strategies to connect women in the CS to pre-exposure prophylaxis (PrEP) services. DESIGN/METHODOLOGY/APPROACH This study conducted in-depth interviews with 27 women involved in the CS eligible for PrEP. Using vignettes, interviews explored attitudes, barriers and facilitators toward PrEP screening, referral and linkage facilitated via a CS stakeholder, an mHealth application or providing PrEP service referrals during detention via a navigator. FINDINGS Most women were, on average, 41.3 years, from racial and ethnic minority groups (56% black/African American; 19% Latinx). Inductive thematic analysis revealed CS involved women expressed mostly positive attitudes toward CS-based PrEP implementation. Younger women were more accepting of and interested in mHealth interventions. Implementation facilitators included leveraging relationships with trusted allies (e.g. "peers") and existing systems collaborations. Recommended implementation strategies included providing HIV and PrEP-specific education and training for system stakeholders and addressing issues related to privacy, system mistrust and stigma. ORIGINALITY/VALUE Results provide a critical foundation for the implementation of interventions to improve PrEP access for women involved in the CS and have important implications for implementation strategies for all adults involved in the CS. Improving access to PrEP among this population may also support progress toward addressing national disparities in PrEP uptake, where women, black and Latinx populations have substantial unmet need.

Abstract
OBJECTIVE We conducted a scoping review to assess barriers to and facilitators of integrating HIV preexposure prophylaxis (PrEP) and family planning (FP) at the patient, provider, and implementation levels, and to identify gaps in knowledge. METHODS We conducted a search of five bibliographic databases from database inception to March 2022: PubMed, CINAHL, Embase, Web of Science and Scopus. Two reviewers screened abstracts and full texts to determine eligibility based on a priori inclusion and exclusion criteria. We categorized studies by their relevance to patient, provider, and implementation barriers, and extracted data based on prespecified elements. RESULTS Our initial search strategy yielded 1151 results, and 34 publications were included. Barriers to PrEP implementation in family planning settings included low PrEP knowledge among patients, hesitance to take PrEP due to perceived stigma, decreased willingness of providers unfamiliar with PrEP to prescribe PrEP, and limited financial and staffing resources that make prescribing and monitoring PrEP difficult. Facilitators included robust training for providers, stigma reduction efforts, leadership engagement, and increased resources specifically in settings with processes in place that ease the process of prescribing and monitoring PrEP. CONCLUSIONS Advances in implementation strategy development, stigma reduction, and drug development will be essential to reinforcing PrEP care in family planning settings and thereby reducing the incidence of HIV in women through highly effective pharmacologic HIV prevention methods.

Abstract
BACKGROUND Long-acting injectable cabotegravir (CAB-LA) represents a new additional option for HIV prevention in people at substantial risk of HIV infection that may fill the gaps in pre-exposure prophylaxis (PrEP) uptake, adherence, and retention in users having difficulty with oral PrEP. Data from clinical trials demonstrated that CAB-LA was safe, highly effective, and well-accepted for HIV prevention. However, the occurrence of breakthrough HIV infections despite timely injections, HIV seroconversion timing and patterns, risk of selection and dissemination of resistance-associated mutations to integrase inhibitors, complexity of follow-up, logistical considerations, and its cost effectiveness compared with oral PrEP constitute significant issues for the integration of CAB-LA into clinical routine. FINDINGS These concerns need to be addressed before moving forward with large-scale implementation programmes. Pilot and implementation projects are required in the following areas: HIV testing algorithms, patient education, clinic procedures, protocols for switching and discontinuation, efficacy and safety in populations not included in clinical trials, and demedicalization processes. The development of models to increase the uptake of, adherence to, and persistence with and after CAB-LA injections will also be of paramount importance for success. Lessons learned from these projects will increase experience, staff expertise, and organizational and training capacities to support the roll-out of this new agent as part of HIV prevention programmes. CONCLUSION CAB-LA has not yet achieved its full potential in HIV prevention, and strong commitment from all stakeholders is required to push CAB-LA as a game-changer in HIV response.

Abstract
INTRODUCTION Pre-exposure prophylaxis (PrEP) is a highly effective HIV prevention strategy and is recommended for populations at risk of HIV, including adolescent girls and young women (AGYW) in HIV endemic settings. However, PrEP continuation and high adherence remain challenges to its impact. Existing PrEP adherence interventions can be time- and cost-intensive. Widescale PrEP delivery will require the identification of layered PrEP support strategies for AGYW with diverse prevention needs. We describe the design of a sequential multiple assignment randomized trial (SMART) to evaluate a PrEP adherence support model using scalable, stepped interventions in AGYW in South Africa. METHODS "PrEP SMART" is a randomized trial in Johannesburg, South Africa, enrolling AGYW who are between 18 and 25 years of age, sexually active, newly initiating PrEP, and have regular access to a mobile phone. Participants are randomized 1:1 to standard-of-care PrEP counseling with either two-way SMS or WhatsApp group adherence support. Adherence is assessed at three months using tenofovir diphosphate (TFV-DP) levels from dried blood spots collected at month 2 to categorize participants as "responders" (TFV-DP ≥500 fmol/punch) or "non-responders" (TFV-DP <500 fmol/punch). AGYW defined as 'non-responders' undergo a secondary 1:1 randomization to either quarterly drug-level feedback counseling or monthly issue-focused counseling, in addition to their first-level intervention. The primary outcome is PrEP adherence at nine months (TFV-DP ≥700 fmol/punch). We will assess the effect of our two initial interventions on TFV-DP levels among responders, assess the effect of our intensified interventions on TFV-DP levels among non-responders, and identify the optimal sequence of adherence interventions through nine months. TRIAL REGISTRATION ClinicalTrials.gov, NCT04038060. Registered on 30 July 2019.
