Public health implications of adapting HIV pre-exposure prophylaxis programs for virtual service delivery in the context of the COVID-19 pandemic: a systematic review

Understanding adaptive responses in PrEP service delivery in Belgian HIV clinics: a multiple case study using an implementation science framework

INTRODUCTION

In Belgium, oral HIV pre-exposure prophylaxis (PrEP) is primarily provided in specialized clinical settings. Optimal implementation of PrEP services can help to substantially reduce HIV transmission. However, insights into implementation processes, and their complex interactions with local context, are limited. This study examined factors that influence providers' adaptive responses in the implementation of PrEP services in Belgian HIV clinics.

METHODS

We conducted a qualitative multiple case study on PrEP care implementation in eight HIV clinics. Thirty-six semi-structured interviews were conducted between January 2021 and May 2022 with a purposive sample of PrEP care providers (e.g. physicians, nurses, psychologists), supplemented by 50 hours of observations of healthcare settings and clinical interactions. Field notes from observations and verbatim interview transcripts were thematically analysed guided by a refined iteration of extended Normalisation Process Theory.

RESULTS

Implementing PrEP care in a centralized service delivery system required considerable adaptive capacity of providers to balance the increasing workload with an adequate response to PrEP users' individual care needs. As a result, clinic structures were re-organized to allow for more efficient PrEP care processes, compatible with other clinic-level priorities. Providers adapted clinical and policy norms on PrEP care (e.g. related to PrEP prescribing practices and which providers can deliver PrEP services), to flexibly tailor care to individual clients' situations. Interprofessional relationships were reconfigured in line with organizational and clinical adaptations; these included task-shifting from physicians to nurses, leading them to become increasingly trained and specialized in PrEP care. As nurse involvement grew, they adopted a crucial role in responding to PrEP users' non-medical needs (e.g. providing psychosocial support). Moreover, clinicians' growing collaboration with sexologists and psychologists, and interactions with PrEP users' family physician, became crucial in addressing complex psychosocial needs of PrEP clients, while also alleviating the burden of care on busy HIV clinics.

CONCLUSIONS

Our study in Belgian HIV clinics reveals that the implementation of PrEP care presents a complex-multifaceted-undertaking that requires substantial adaptive work to ensure seamless integration within existing health services. To optimize integration in different settings, policies and guidelines governing PrEP care implementation should allow for sufficient flexibility and tailoring according to respective local health systems.

Effectiveness of PrEPTECH: Findings From a 180-Day Randomized Controlled Trial of a Pre-Exposure Prophylaxis Telehealth Intervention

BACKGROUND

Telehealth approaches are increasingly being used to provide access to pre-exposure prophylaxis (PrEP), an effective but underused HIV prevention modality. This randomized controlled trial of PrEPTECH, a telehealth intervention for the provision of HIV PrEP, seeks to assess its effects on PrEP access.

METHODS

Young men who have sex with men and transgender women in Florida and California with an indication for PrEP were randomly assigned in a 1:1 allocation to receive access to PrEPTECH or a control condition, access to an online listing of PrEP resources in their communities. This intent-to-treat analysis used logistic and linear regression to compare self-reported PrEP initiation, use, and coverage between control and intervention arm participants at 90 days and 180 days of follow-up.

RESULTS

A total of 229 participants with a mean age of 23.7 years, 77.3% people of color enrolled in PrEPTECH. At 90 days, postbaseline initiation of PrEP was significantly higher among those in the PrEPTECH arm than among controls (odds ratio [OR]: 6.63, 95% confidence interval [CI]: 2.54 to 17.35), and this held true by 180 days post baseline. The count of sex acts for which participants were not protected by PrEP, PrEP adherence, and recent PrEP use at 180 days post baseline were not significantly different between the study arms.

CONCLUSIONS

Receiving access to a telehealth platform for PrEP access increased PrEP initiation in this cohort of young, predominantly non-White sexual and gender minorities. PrEP telehealth may be a worthy avenue for providing access to PrEP for these populations, but additional strategies may be needed to promote adherence and persistence of PrEP use.

Leveling Up PrEP: Implementation Strategies at System and Structural Levels to Expand PrEP Use in the United States

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.

Digital Interventions to Enhance PrEP Uptake and Adherence Through Stigma Reduction

PURPOSE OF REVIEW

Although pre-exposure prophylaxis (PrEP) is effective for reducing risk of HIV transmission, stigma persists as a barrier to HIV prevention. Digital technologies present opportunities to access hard-to-reach populations and increase the efficiency of established interventions. This review examines current digital interventions addressing stigma to improve PrEP-related outcomes.

RECENT FINDINGS

Digital technologies are increasingly used for HIV prevention and include a wide range of formats. Recent interventions focused on stigma and PrEP tend to engage mobile phone-related technology and focus on younger populations with particular attention to men who have sex with men and transgender women. Digital interventions that address stigma are promising for improving PrEP-related outcomes. No single technology currently demonstrates consistent superiority. Limited access to PrEP and heightened stigma in under-resourced countries present challenges for interventions supporting diverse communities. Further research should examine how digital interventions can reduce stigma beyond the individual level to enhance PrEP use and explore opportunities to improve and integrate approaches to stigma measurement.

Online-Mediated HIV Pre-exposure Prophylaxis Care and Reduced Monitoring Frequency for Men Who Have Sex With Men: Protocol for a Randomized Controlled Noninferiority Trial (EZI-PrEP Study)

BACKGROUND

Daily and event-driven HIV pre-exposure prophylaxis (PrEP) with oral tenofovir-emtricitabine is highly effective to prevent HIV in men who have sex with men (MSM). PrEP care generally consists of in-clinic monitoring every 3 months that includes PrEP dispensing, counseling, and screening for HIV and sexually transmitted infections (STIs). However, the optimal frequency for monitoring remains undetermined. Attending a clinic every 3 months for monitoring may be a barrier for PrEP. Online-mediated PrEP care and reduced frequency of monitoring may lower this barrier.

OBJECTIVE

The primary objective of this study is to establish the noninferiority of online PrEP care (vs in-clinic care) and monitoring every 6 months (vs every 3 months). The secondary objectives are to (1) examine differences between PrEP care modalities regarding incidences of STIs, HIV infection, and hepatitis C virus infection; retention in PrEP care; intracellular tenofovir-diphosphate concentration; and satisfaction, usability, and acceptability of PrEP care modalities; and (2) evaluate associations of these study outcomes with sociodemographic, behavioral, and psychological characteristics.

METHODS

This study is a 2×2 factorial, 4-arm, open-label, multi-center, randomized, controlled, noninferiority trial. The 4 arms are (1) in-clinic monitoring every 3 months, (2) in-clinic monitoring every 6 months, (3) online monitoring every 3 months, and (4) online monitoring every 6 months. The primary outcome is a condomless anal sex act with a casual partner not covered or insufficiently covered by PrEP (ie, "unprotected act") as a proxy for HIV infection risk. Eligible individuals are MSM, and transgender and gender diverse people aged ≥18 years who are eligible for PrEP care at 1 of 4 participating sexual health centers in the Netherlands. The required sample size is 442 participants, and the planned observation time is 24 months. All study participants will receive access to a smartphone app, which contains a diary. Participants are requested to complete the diary on a daily basis during the first 18 months of participation. Participants will complete questionnaires at baseline and 6, 12, 18, and 24 months. Dried blood spots will be collected at 6 and 12 months for assessment of intracellular tenofovir-diphosphate concentration. Incidence rates of unprotected acts will be compared between the online and in-clinic arms, and between the 6-month and 3-month arms. Noninferiority will be concluded if the upper limit of the 2-sided 97.5% CI of the incidence rate ratio is <1.8.

RESULTS

The results of the main analysis are expected in 2024.

CONCLUSIONS

This trial will demonstrate whether online PrEP care and monitoring every 6 months is noninferior to standard PrEP care in terms of PrEP adherence. If noninferiority is established, these modalities may lower barriers for initiating and continuing PrEP use and potentially reduce the systemic burden for PrEP providers.

Effectiveness, Acceptability, and Feasibility of a Telehealth HIV Pre-Exposure Prophylaxis Care Intervention Among Young Cisgender Men and Transgender Women Who Have Sex With Men: Protocol for a Randomized Controlled Trial

BACKGROUND

Despite its promise for HIV prevention, the uptake of pre-exposure prophylaxis (PrEP) has been slow, and there have been substantial inequities in PrEP access. Young men who have sex with men and transgender women of color are most in need of PrEP and least likely to have that need fulfilled. PrEP telehealth care, which provides remote PrEP care via electronic communication, seems well suited to address several of the challenges of PrEP provision, including discomfort with stigmatizing and difficult-to-access health care systems, transportation challenges, and privacy concerns, and address disparities in PrEP access. Research suggests that PrEP telehealth care has promise and is a favored option for many prospective recipients of PrEP. However, despite growing attention to telehealth approaches as an avenue for increasing access to PrEP amidst the COVID-19 pandemic, there have been no published randomized controlled trials (RCTs) on PrEP telehealth care to date, making it difficult to draw strong conclusions about the advantages or disadvantages of telehealth compared with usual PrEP care. We developed PrEPTECH, a telehealth intervention that focuses specifically on alleviating issues of stigma, access, cost, and confidentiality for young people with risk factors for HIV infection who are seeking PrEP care. Leveraging data from the 2017 observational pilot study, we redesigned and enhanced PrEPTECH.

OBJECTIVE

This study aims to assess the effectiveness, acceptability, and feasibility of a telehealth HIV PrEP care intervention, PrEPTECH, in increasing PrEP uptake.

METHODS

This is the protocol for an RCT of young cisgender men and transgender women who have sex with men in 4 regions within the United States: the San Francisco Bay Area, California; Los Angeles County, California; Miami-Dade County, Florida; and Broward County, Florida. Participants in the intervention arm received access to a web-based telehealth program, PrEPTECH, which offers a fully web-based pathway to PrEP, whereas those in the control arm received access to a dynamic web page containing publicly available informational resources about PrEP. Follow-up data collection occurred at 3 and 6 months. An analysis will be conducted on outcomes, including PrEP initiation, persistence, adherence, coverage, and medication prescription, as well as PrEPTECH acceptability and feasibility.

RESULTS

The study was funded in 2019 and received institutional review board approval in 2020. The PrEPTECH intervention was developed over the next 1.5 years. Study recruitment was launched in February 2022 and completed in September 2022, with 229 participants recruited in total. Data collection was completed in April 2023.

CONCLUSIONS

The results of this RCT will offer valuable evidence regarding the effectiveness, acceptability, and feasibility of telehealth HIV PrEP care interventions among young cisgender men and transgender women who have sex with men.

Barriers and Facilitators to Pre-Exposure Prophylaxis by Men Who Have Sex with Men and Community Stakeholders in Malaysia

BACKGROUND

Men who have sex with men (MSM) in Malaysia are disproportionately affected by HIV. Pre-exposure prophylaxis (PrEP) is an evidence-based HIV prevention strategy; yet, uptake remains low among Malaysian MSM, who have a limited understanding of barriers to PrEP.

METHODS

We employed the nominal group technique (NGT), a structured mixed-methods strategy to understand the barriers and facilitators to PrEP use among Malaysian MSM, combined with a qualitative focus group. Six virtual focus group sessions, three among MSM (n = 20) and three among stakeholders (n = 16), were conducted using a video-conferencing platform. Rank-ordering of barriers from NGT was recorded, and thematic analysis was conducted for content.

RESULTS

Similar barriers were reported by MSM and community stakeholders, with aggregated costs associated with PrEP care (e.g., consultation with a clinician, medication, laboratory testing) being the greatest barrier, followed by limited knowledge and awareness of PrEP. Additionally, the lack of access to PrEP providers, the complex clinical protocol for PrEP initiation and follow-up, and social stigma undermined PrEP delivery. Qualitative discussions identified potential new strategies to overcome these barriers, including expanded outreach efforts to reach hard-to-reach MSM, a 'one-stop' delivery model for PrEP services, a patient-centered decision aid to guide PrEP uptake, and easy access to LGBT-friendly PrEP providers.

CONCLUSION

Current barriers may be overcome through governmental subsidy for PrEP and evidence-informed shared decision aids to support both MSM and PrEP providers.

Understanding HIV Pre-Exposure Prophylaxis Questions of U.S. Health Care Providers: Unique Perspectives from the PrEPline Clinical Teleconsultation Service

Introduction: Fewer than a quarter of people considered to have factors associated with HIV acquisition are prescribed pre-exposure prophylaxis (PrEP) in the United States. Prior studies demonstrate disparities in provider comfort and knowledge regarding PrEP, suggesting a need for provider capacity building to support widespread PrEP availability. This study examined real-world PrEP clinical questions/cases from providers to a teleconsultation service to identify knowledge gaps and improve PrEP-related training materials and clinical guidelines. Methods: The National Clinician Consultation Center (NCCC) PrEPline provides educational teleconsultation services on clinical decision-making related to PrEP for U.S. health care providers. The NCCC PrEP consultation data collected between 2017 and 2020 were reviewed and systematically categorized by clinical topics, subtopics, and complexity levels (low, moderate, and high). Results: Within the study period, the PrEPline provided 1,754 teleconsultations. More than three quarters came from advanced practice nurses and physicians. The topics of questions commonly focused on medication-based HIV prevention strategies (22.7%), PrEP laboratory ordering/monitoring (17.4%), and side effects and contraindications (14.6%). The majority of teleconsultations (57.9%) involved sharing information that was directly available/addressed in the Centers for Disease Control and Prevention (CDC) 2017 PrEP Guidelines (i.e., low complexity). Discussion: The low frequency of consultations from nonphysician and non-nurse practitioner providers may suggest a need for increased training and collaborative opportunities for other types of providers. The high percentage of low-complexity inquiries may reveal a desire for capacity-building materials specifically designed for practicing providers (e.g., abridged versions of guidelines). This study may inform future research, best clinical practices, and aid in the development of training materials to increase providers' HIV prevention comfort and knowledge.

Characterizing the Impact of the COVID-19 Pandemic on HIV PrEP care: A Review and Synthesis of the Literature

The global COVID-19 pandemic and associated lockdown measures have caused disruptions to sexual health services and created additional barriers to the continuity of HIV pre-exposure prophylaxis (PrEP) among key populations. This review provides an examination of the influences of the pandemic on engagement in the PrEP care continuum. Using the PRISMA guideline, 46 studies were included in this review and the synthesis. Most of the studies were conducted in high-income settings through quantitative analysis. A majority of studies examining the changes in PrEP use suggested a decline or discontinuation in PrEP uptake during the pandemic. The most common reasons for stopping using PrEP were perceived barriers to PrEP-related care, having reduced sexual behaviors and fewer sexual partners, and reduced perceived risk of HIV infection. Limited studies documenting an increase in PrEP uptake were all in specific PrEP optimizing programs. During the pandemic, there is also an emerging trend of switching to on-demand PrEP from daily oral PrEP. Future studies should understand the mechanism of strategies that facilitated the improvements during the pandemic. PrEP implementation programs should consider alternative PrEP modalities and provide consistent and comprehensive knowledge about correct information.

Telehealth Interventions for HIV in Low- and Middle-Income Countries

PURPOSE OF REVIEW

This review summarizes technology-based interventions for HIV in low- and middle-income countries (LMICs). We highlight potential benefits and challenges to using telehealth in LMICs and propose areas for future study.

RECENT FINDINGS

We identified several models for using telehealth to expand HIV health care access in LMICs, including telemedicine visits for pre-exposure prophylaxis (PrEP) and antiretroviral therapy (ART) services, telementoring programs for providers, and virtual peer-support groups. Emerging data support the acceptability and feasibility of these strategies. However, further investigations are needed to determine whether these models are scalable and sustainable in the face of barriers related to cost, infrastructure, and regulatory approval. HIV telehealth interventions may be a valuable approach to addressing gaps along the HIV care cascade in LMICs. Future studies should focus on strategies for expanding existing programs to scale and for assessing long-term clinical outcomes.
