Participant experiences and facilitators and barriers to pill use among men who have sex with men in the iPrEx pre-exposure prophylaxis trial in San Francisco

Acceptance of digital phenotyping linked to a digital pill system to measure PrEP adherence among men who have sex with men with substance use

Once-daily oral HIV pre-exposure prophylaxis (PrEP) is an effective strategy to prevent HIV, but is highly dependent on adherence. Men who have sex with men (MSM) who use substances face unique challenges maintaining PrEP adherence. Digital pill systems (DPS) allow for real-time adherence measurement through ingestible sensors. Integration of DPS technology with other digital health tools, such as digital phenotyping, may improve understanding of nonadherence triggers and development of personalized adherence interventions based on ingestion behavior. This study explored the willingness of MSM with substance use to share digital phenotypic data and interact with ancillary systems in the context of DPS-measured PrEP adherence. Adult MSM on PrEP with substance use were recruited through a social networking app. Participants were introduced to DPS technology and completed an assessment to measure willingness to participate in DPS-based PrEP adherence research, contribute digital phenotyping data, and interact with ancillary systems in the context of DPS-based research. Medical mistrust, daily worry about PrEP adherence, and substance use were also assessed. Participants who identified as cisgender male and were willing to participate in DPS-based research (N = 131) were included in this subsample analysis. Most were White (76.3%) and non-Hispanic (77.9%). Participants who reported daily PrEP adherence worry had 3.7 times greater odds (95% CI: 1.03, 13.4) of willingness to share biometric data via a wearable device paired to the DPS. Participants with daily PrEP adherence worry were more likely to be willing to share smartphone data (p = 0.006) and receive text messages surrounding their daily activities (p = 0.003), compared to those with less worry. MSM with substance use disorder, who worried about PrEP adherence, were willing to use DPS technology and share data required for digital phenotyping in the context of PrEP adherence measurement. Efforts to address medical mistrust can increase advantages of this technology for HIV prevention.

Psychological and Behavioural Within-participant Predictors of Adherence to Oral HIV Pre-Exposure Prophylaxis (PrEP)

Oral PrEP's effectiveness relies on adequate adherence during periods of substantial HIV risk. Since most PrEP users will miss doses, understanding predictors within participants can help to explain adherence. We used a cross-sectional, within-participant design with 67 gay, bisexual, and other men who have sex with men taking PrEP daily. Using a questionnaire, informed by the Information Motivation Behavioral Skills Model, participants were asked about an adherent and a non-adherent episode. PrEP non-adherence was associated with non-normality of the day (p < .001), being out of the home (p < .001), weekend days (p = .01), having company (p = .02), using substances (p = 0.02), not using reminders (p = .03), lower PrEP information (p = .04), lower behavioural skills (p < .001) and less positive affect (p = .002). PrEP adherence assessment could focus on situational variations, supporting the construction of alternative strategies to facilitate adherence in these situations.

Evaluating the Feasibility and Acceptability of a Digital Pre-Exposure Prophylaxis Navigation and Activation Intervention for Racially and Ethnically Diverse Sexual and Gender Minority Youth (PrEPresent): Protocol for a Pilot Randomized Controlled Trial

BACKGROUND

To end the HIV epidemic by 2030, we must double down on efforts to tailor prevention interventions to both young men who have sex with men and transgender and nonbinary youth. There is an urgent need for interventions that specifically focus on pre-exposure prophylaxis (PrEP) uptake in sexual and gender minority youth (SGMY) populations. There are several factors that impact the ability of SGMY to successfully engage in the HIV prevention continuum, including uptake of PrEP. Patient activation, having the knowledge, skills, and self-efficacy to manage one's health, is an important indicator of willingness and ability to manage one's own health and care autonomously. Patient navigation also plays an important role in helping SGMY access PrEP and PrEP care, as navigators help guide patients through the health care system, set up medical appointments, and get financial, legal, and social support.

OBJECTIVE

This study aims to evaluate the feasibility and acceptability of a digital PrEP navigation and activation intervention among a racially and ethnically diverse sample of SGMY living in the Los Angeles area.

METHODS

In phase 1, we will conduct formative research to inform the development of PrEPresent using qualitative data from key informant interviews involving PrEP care providers and navigators and working groups with SGMY. In phase 2, we will complete 2 rounds of usability testing of PrEPresent with 8-10 SGMY assessing both the intervention content and mobile health delivery platform to ensure features are usable and content is understood. In phase 3, we will conduct a pilot randomized controlled trial to evaluate the feasibility and acceptability of PrEPresent. We will randomize, 1:1, a racially and ethnically diverse sample of 150 SGMY aged 16-26 years living in the Los Angeles area and follow participants for 6 months.

RESULTS

Phase 1 (formative work) was completed in April 2021. Usability testing was completed in December 2021. As of June 2023, 148 participants have been enrolled into the PrEPresent pilot randomized controlled trial (phase 3). Enrollment is expected to be completed in July 2023, with final results anticipated in December 2023.

CONCLUSIONS

The PrEPresent intervention aims to bridge the gaps in PrEP eligibility and PrEP uptake among racially and ethnically diverse SGMY. By facilitating the delivery of PrEP navigation and focusing on improving patient activation, the PrEPresent intervention has the potential to positively impact the PrEP uptake cascade in the HIV care continuum as well as serve as a model for the tailoring of PrEP interventions based on behavior-based qualifications for PrEP instead of generalized gender-based eligibility.

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.

Perspectives on long-acting formulations of pre-exposure prophylaxis (PrEP) among men who have sex with men who are non-adherent to daily oral PrEP in the United States

INTRODUCTION

Pre-exposure prophylaxis (PrEP) persistence among men who have sex with men (MSM) in real world clinical settings for HIV prevention is suboptimal. New longer-acting formulations of PrEP are becoming available, including injectables, subdermal implants, and other oral medications. These longer-acting formulations have the potential to improve retention among those who have challenges remaining adherent to daily oral PrEP.

METHODS

We interviewed 49 MSM who had initiated but discontinued oral PrEP at three diverse clinics across the United States. We examined participants' perspectives about long-acting PrEP formulations and how long-acting options could affect PrEP use using thematic analysis.

RESULTS

Participants were not very knowledgeable about long-acting formulations of PrEP but were open to learning about them and considering use. Participants were concerned about safety and efficacy of products given that they were still newer and/or in development. Finally, participants had clear preferences for oral pills, injectables, and then subdermal implants and were most interested in options that reduced the number of visits to the clinic.

CONCLUSION

Long-acting formulations of PrEP are acceptable to MSM with suboptimal PrEP persistence and have the potential to improve PrEP persistence. However, many felt they needed more information on safety, efficacy, and use to consider these options. As these long-acting formulations are implemented, public health campaigns and clinical interventions to encourage may maximize uptake particularly among those who are not currently adherent to daily oral PrEP.

Qualitative Examination of the Impact of the COVID-19 Pandemic on Access and Adherence to Pre-exposure Prophylaxis (PrEP) Among Sexual and Gender Minorities

During the COVID-19 pandemic, pre-exposure prophylaxis (PrEP) access and adherence decreased nationwide. This study examined pandemic-related disruptions to PrEP access and adherence among clients of a health center (Center) in Los Angeles, California. Clients (n = 25) and Center personnel (n = 11) completed qualitative interviews from March to July 2021. Although the Center provided options for remote PrEP care (i.e., telehealth, STI self-testing kits, and prescription delivery), clients experienced difficulty navigating services or lacked equipment for telehealth. More than half (n = 13) of clients discontinued PrEP during COVID-19 due to decreased sexual partners, relocation, or insurance status changes. Among those who continued PrEP, the majority reported no change in adherence, while a minority reported worsening adherence due to distractions/forgetting, prescription refill issues, lack of insurance coverage, and fear of completing in-person visits. Findings highlight the challenges of navigating PrEP services during COVID-19 and suggest PrEP services enhancement to adapt to crisis events.

Exploring preferences and decision-making about long-acting injectable HIV pre-exposure prophylaxis (PrEP) among young sexual minority men 17-24 years old

Intramuscular cabotegravir for long-acting injectable HIV pre-exposure prophylaxis (i.e., LAI-PrEP) was approved by the U.S. FDA in 2021. We sought to explore LAI-PrEP decision-making among a nationwide sample of young sexual minority men (YSMM) 17-24 years old. In 2020, HIV-negative/unknown YSMM (n = 41) who met CDC criteria for PrEP were recruited online to participate in synchronous online focus groups eliciting preferences and opinions about LAI-PrEP, as well as the impact of a potential self-administered option. Data were analyzed using inductive and deductive thematic analysis with constant comparison. Preferences and decision-making about LAI-PrEP varied widely among YSMM, with participants frequently comparing LAI-PrEP to oral PrEP regimens. We identified five key themes related to LAI-PrEP decision-making including concerns about adherence to PrEP dosing and clinic appointments, awareness and knowledge of PrEP safety and efficacy data, comfort with needles, minimizing PrEP stigma, and considerations of self-administration. YSMM acknowledged more PrEP options as beneficial to supporting uptake and persistence.

Patient and Physician Preferences Regarding Long-Acting Pre-Exposure Prophylaxis and Antiretroviral Therapy: A Mixed-Methods Study in Southern California, USA

Antiretroviral therapy (ART) and pre-exposure prophylaxis (PrEP) are key strategies in ending the HIV epidemic. However, poor adherence to daily ART and PrEP increases the risk of HIV transmission and acquisition. Long-acting ART and PrEP formulations attempt to improve adherence through providing long-lasting forms of the medication delivered through different routes of administration: oral (potentially monthly), injection (1-6 months), and subdermal implant (up to annually). This study explored patient and physician preferences for long-acting ART and PrEP as well as adherence support strategies. Adult patients (n = 42) with experience taking ART or PrEP participated in individual interviews or focus groups. Physicians (n = 13) currently prescribing ART and/or PrEP completed an online questionnaire. Rapid qualitative analysis systematically synthesized qualitative data, and descriptive statistics examined survey responses. Patients supported improved adherence as a top potential advantage of long-acting ART and PrEP, and reduced internal stigma as a strong benefit specific to long-acting ART. Annual coverage offered through subdermal implants had strong appeal; however, oral was the preferred modality for long-acting ART and PrEP. Patients preferred injectable ART and PrEP if concurrently receiving hormone therapy injections. Side effects, medication cost, and treatment accessibility were potential barriers. Patients preferred calendar tracking and text messages/phone reminders for adherence supports. Physicians reported that they would reduce clinic visits and HIV testing for all patients on long-acting PrEP, except men who have sex with men who would continue to complete HIV testing every 3 months. Physicians were mixed on whether they believed long-acting ART and PrEP would improve patient adherence. Overall, findings demonstrate the potential benefits of long-acting ART and PrEP, while highlighting the need to obtain additional information to address treatment concerns.

Perceived Barriers to and Facilitators of Long-Acting Injectable HIV PrEP Use Among Black, Hispanic/Latino, and White Gay, Bisexual, and Other Men Who Have Sex With Men

Long-acting injectable pre-exposure prophylaxis (LAI-PrEP) was recently approved for HIV prevention as an alternative to daily oral PrEP. We explored preferences and attitudes toward LAI-PrEP among Black, Hispanic/Latino, and White gay, bisexual, and other men who have sex with men (GBM) using focus groups (n = 13) and in-depth interviews (n = 17). Participants expressed differing levels of interest in LAI-PrEP. While important benefits of LAI-PrEP included convenience, provider-facilitated PrEP discussion, and expansion of PrEP options, participants raised concerns about treatment efficacy and side effects, discomfort with needles/injections, cost, and frequency of clinic visits. Our findings highlight ongoing challenges with accessing HIV-prevention tools and provide guidance for developing strategies to enhance LAI-PrEP uptake among GBM.

Facilitators for retaining men who have sex with men in pre-exposure prophylaxis care in real world clinic settings within the United States

BACKGROUND

Pre-exposure prophylaxis (PrEP) can significantly reduce HIV acquisition especially among communities with high HIV prevalence, including men who have sex with men (MSM). Much research has been finding suboptimal PrEP persistence; however, few studies examine factors that enhance PrEP persistence in real-world settings.

METHODS

We interviewed 33 patients who identified as MSM at three different PrEP clinics in three regions of the U.S. (Northeast, South, Midwest). Participants were eligible if they took PrEP and had been retained in care for a minimum of 6 months. Interviews explored social, structural, clinic-level and behavioral factors that influencing PrEP persistence.

RESULTS

Through thematic analysis we identified the following factors as promoting PrEP persistence: (1) navigation to reduce out-of-pocket costs of PrEP (structural), (2) social norms that support PrEP use (social), (3) access to LGBTQ + affirming medical providers (clinical), (4) medication as part of a daily routine (behavioral), and (5) facilitation of sexual health agency (belief).

DISCUSSION

In this sample, persistence in PrEP care was associated with structural and social supports as well as a high level of perceived internal control over protecting their health by taking PrEP. Patients might benefit from increased access, LGBTQ + affirming medical providers, and communications that emphasize PrEP can promote sexual health.

Perceptions and Practicalities Influencing Pre-exposure Prophylaxis Adherence Among Men Who Have Sex with Men in England

PrEP is highly effective for HIV prevention but requires adequate adherence. In this paper we use the perceptions and practicalities approach (PAPA) to identify factors that influenced PrEP adherence using qualitative data from the PROUD study. From February 2014 to January 2016, we interviewed 41 gay, bisexual and other men-who-have-sex-with-men and one trans woman who were enrolled in the study. We purposively recruited participants for interview based on trial arm allocation, adherence and sexual risk behaviours. The interviews were conducted in English, audio-recorded, transcribed, coded and analysed using framework analysis. Participants in general were highly motivated to use and adhere to PrEP, and this was linked to strong perceptions of personal necessity for PrEP as they felt at risk of HIV and viewed PrEP as highly effective. On the other hand, concerns about side effects and HIV resistance did inhibit PrEP initiation and adherence although this was uncommon. Practical factors such as daily routine, existing habitual pill-taking and pill storage impacted adherence. Drug and alcohol use rarely caused participants to miss doses. These findings indicate that using the principals of PAPA to unpick influencers of PrEP use, could help tailor adherence support in PrEP programmes.

The Role of Alcohol-Related Behavioral Risk in the Design of HIV Prevention Interventions in the Era of Antiretrovirals: Alcohol Challenge Studies and Research Agenda

HIV/AIDS remains a significant health threat and alcohol is a robust contributing factor. After 25 years of alcohol challenge studies investigating alcohol-related behavioral risk (ARBR), much has been learned delineating how drinking influences sexual transmission. We examine this research and consider its relevance for interventions in the era of antiretrovirals. We consider prototypic alcohol challenge methods, illustrative findings, and prevention/intervention implications, noting three perspectives: (a) scale up/extend existing interventions, including identifying under-targeted risk groups and intersecting with PrEP/PEP interventions; (b) modify existing interventions by cultivating psychoeducational content related to alcohol expectancies, alcohol myopia, sexual arousal, risk perception, sexual abdication, and condom use resistance; and (c) innovate new interventions through Science of Behavior Change approaches and repurposing ARBR paradigms. Finally, we suggest research directions concluding that until HIV incidence diminishes significantly, psychosocial interventions addressing the nexus of alcohol use, sexual transmission, and adherence to biomedical protocols will be an important priority.

Adaptation of a Theory-Based Social Networking and Gamified App-Based Intervention to Improve Pre-Exposure Prophylaxis Adherence Among Young Men Who Have Sex With Men in Bangkok, Thailand: Qualitative Study

BACKGROUND

HIV disproportionately affects young Thai men who have sex with men (YMSM). Recent studies report a high incidence and prevalence of HIV among Thai YMSM. The Thai national guidelines have recommended pre-exposure prophylaxis (PrEP) since 2014 for key populations; free PrEP has been piloted since 2019. Smartphone-based mobile health (mHealth) interventions provide an optimal platform for innovative PrEP adherence interventions for Thai YMSM.

OBJECTIVE

This study aims to adapt the P3 (Prepared, Protected, emPowered) app, developed with YMSM and transwomen in the United States to improve PrEP adherence and persistence for YMSM in Thailand. The app aims to provide daily adherence support and addresses gaps in staff available for large-scale PrEP rollout needed to see population-level effects of HIV prevention.

METHODS

We conducted focus group discussions (FGDs) with YMSM and key informant interviews (KIIs) with PrEP care providers in Bangkok, Thailand, to investigate PrEP adherence facilitators and barriers, preferences for functions and features in mHealth apps among YMSM, and how to best adapt the P3 app to the Thai context. We conducted four FGDs with 4-8 participants per group and 15 KIIs.

RESULTS

For FGDs, 23 YMSM participated with a mean age of 20 years (range 18-21), 96% (22/23) enrolled in full-time education, and all owned smartphones. The mean age of KII participants was 40 (range 26-60) years; most were state health service providers, with the majority being counselors (6/15, 40%) and physicians (6/15, 40%). Overall, the facilitators and barriers for PrEP adherence identified were similar to those of MSM and YMSM globally including the United States. Key themes included general recommendations for improving mHealth apps in Thailand, such as presenting reliable information in an appealing format, minimizing privacy risks, and addressing connectivity challenges. Additional themes focused on P3 Thailand adaptations and were related to cultural and stylistic preferences, engagement strategies, and recommendations for new functions. To develop the adapted app, P3 Thailand, these findings were balanced with resource limitations resulting in the prioritization of minor modifications: changes in app esthetics (color scheme, iconography, and imagery) and changes in the presentation of information in two of the app's features. FGDs identified similar PrEP adherence facilitators and barriers to those already addressed within the app.

CONCLUSIONS

The core elements of the P3 app address major PrEP facilitators and barriers for Thai YMSM; however, changes to the app features, including stylistic presentation, were needed to appropriately customize the app to the Thai context. Given the similarities of facilitators and barriers for PrEP adherence globally, adapting existing PrEP mHealth solutions based on input from end users and key informants provides a promising approach. However, partnerships with local app designers and developers can improve the adaptation process and final product.

Pre-Exposure Prophylaxis (PrEP) Adherence Questionnaire: Psychometric Validation among Sexually Transmitted Infection Patients in China

BACKGROUND

Ensuring adherence guarantees the efficacy of pre-exposure prophylaxis (PrEP).

METHODS

We conducted a cross-sectional study among 816 sexually transmitted infection (STI) patients in Shanghai. The questionnaire included self-reported demographic characteristics, self-administered items on adherence to free oral PrEP, and PrEP uptake behavior measurement. We conducted item analysis, reliability analysis, validity analysis and receiver operating characteristic (ROC) curve analysis.

RESULTS

Not all items were considered acceptable in the item analysis. The questionnaire had a McDonald's ω coefficient of 0.847. The scale-level content validity index (CVI) was 0.938 and the item-level CVI of each item ranged from 0.750 to 1. In exploratory factor analysis, we introduced a four-factor model accounting for 79.838% of the aggregate variance, which was validated in confirmatory factor analysis. Adding PrEP adherence questionnaire scores contributed to prediction of PrEP uptake behavior (p < 0.001) in regression analysis. The maximum area under the ROC curve was 0.778 (95% IC: 0.739-0.817).

CONCLUSION

The PrEP adherence questionnaire presented psychometric validation among STI patients.

Factors associated with self-reported adherence to daily oral pre-exposure prophylaxis among men who have sex with man and transgender women: PrEP Brasil study

Understanding the factors associated with pre-exposure prophylaxis (PrEP) adherence may help in the development of strategies to support, motivate and sustain PrEP use. This study estimated self-reported adherence, described perceived barriers and facilitators and investigated factors associated with adherence to daily oral PrEP among men who have sex with man (MSM) and transgender women after 1 year of PrEP use in Brazil. PrEP Brasil was a prospective, multicentre, open-label demonstration study with MSM and transgender women at high risk for HIV infection. We used logistic regression to evaluate factors associated with complete adherence (not forgetting to take any pills in the past 30 days) at week 48. Of 338 participants included in this analysis, 60% reported complete adherence to daily oral PrEP at week 48. Perceived barriers and facilitators to daily oral PrEP were reported by 38.2% and 98.5%, respectively. The most reported barrier and facilitator were 'I forgot to take my pills' (19.2%) and 'Associate PrEP with a daily activity/task' (58.6%), respectively. In final multivariable analysis, living in Rio de Janeiro (aOR: 0.38; 95% CI: 0.20-0.73), being transgender women (aOR: 0.22; 95% CI: 0.07-0.73), reporting stimulant use (a OR: 0.40; 95% CI: 0.20-0.80) and having any perceived barriers to daily oral PrEP (aOR: 0.12; 95% CI: 0.07-0.23) were associated with decreased odds of complete adherence. Our findings provide information for developing the best practices to promote PrEP adherence in the Brazilian context.

The effectiveness of tenofovir-based pre-exposure prophylaxis for prevention of HIV acquisition among sub-Saharan African women at high risk: a systematic review

Introduction

women in sub-Saharan Africa (SSA) are disproportionately affected by the HIV epidemic. In 2019, they constituted 59% of new infections; thus, they remain a key population for control. Public health interventions to prevent acquisition of HIV in this high-risk population are urgently needed. Tenofovir-based pre-exposure prophylaxis (TFV-PrEP) has been shown to reduce HIV infections in other key populations. However, comprehensive evidence regarding TFV-PrEP effectiveness in women living in SSA has not been determined. Therefore, we undertook a systematic review to determine the effectiveness of tenofovir-1% (TFV-1%) vaginal gel, oral tenofovir (TFV) and tenofovir-emtricitabine (TDF-FTC) pre-exposure prophylaxis for primary acquisition of HIV in at-risk women living in SSA.

Methods

OVID Medline, Embase, CENTRAL, Web of Science and Clinical Trials.gov were searched for eligible studies from 1^st January 2020 to 31^st July 2020. Only randomised controlled trials (RCTs) conducted in women living in SSA were included. Measures of effectiveness (hazard ratios (HR), incidence rate ratios (IRR)) were extracted from individual studies to determine the effectiveness of TFV-PrEP in preventing HIV infection among at-risk women living in SSA.

Results

from 2002 non-duplicate articles, four RCTs evaluating the effectiveness of one or more of the interventions against placebos were included. TFV-1% vaginal gel, oral TDF or TDF-FTC were not effective in preventing the acquisition of HIV infection in women living in SSA. However, poor adherence by study participants could have confounded the true effectiveness of TFV-PrEP in this high risk population. Meta-analysis was not conducted given the limited number of eligible studies identified from the search.

Conclusion

the current evidence does not support the effectiveness of TFV-PrEP for HIV in SSA women. More studies aimed at addressing factors driving low adherence to HIV interventions in this high risk population are urgently needed in order to improve the design of future RCTs leading to the determination of more reliable estimates of TFV-1% vaginal gel or oral TDF or TDF-FTC effectiveness. Protocol registration: this systematic review was not registered in PROSPERO.

Pre-exposure prophylaxis makes it possible to better live one's sexuality and guide men who have sex with men towards a responsible approach to their health: a phenomenological qualitative study about primary motivations for PrEP

Background

Pre-exposure prophylaxis (PrEP) for HIV is instrumental in the prevention of HIV for HIV-uninfected persons, by drastically reducing the risk of acquisition in the case of high-risk exposures. Despite its demonstrated efficacy, it remained under-prescribed in France until 2018. The principal aim of this study was to understand the motivations of Men who have Sex with Men (MSM) who started using PrEP in Montpellier, France.

Methods

A phenomenological study was undertaken, using semi-structured interviews with twelve participants attending the University Hospital of Montpellier for PrEP. Interviews were analysed by means of triangulation up to the point of theoretical saturation, using a semio-pragmatic method.

Results

Fear of HIV infection, personalised regular follow-up, and the wish to take care of one’s health were the primary motivational factors. PrEP allows for a better sexual life restoring a sense of freedom despite the risks of STI, deemed manageable by PrEPers. PrEP does not modify long-term risk-taking behaviours but helps them better live their own sexuality and guides them towards a responsible approach to sexuality. Unclear information on PrEP, delivered by their family doctor, public campaigns or the media, leads to misrepresentations or negative social representation, including within the MSM community, which may delay its implementation.

Conclusions

Fear of HIV infection and the benefits of regular medical follow-up to take care of one’s health were motivational factors of importance for the use of PrEP by MSM in this study. PrEP transforms all existential dimensions of their lived experience, improving sexual identity and happiness. There is a need to improve professional awareness of the effectiveness of PrEP and to develop a patient centered approach, to disseminate information more widely to the general public and among MSM to reduce stigmatisation.

Pre-exposure Prophylaxis (PrEP) for HIV Prevention Among Men Who Have Sex with Men (MSM): A Scoping Review on PrEP Service Delivery and Programming

Pre-exposure prophylaxis (PrEP) is an evidence-based new biomedical HIV prevention intervention, which involves the pre-emptive use of daily (or event-based) antiretroviral drugs, to reduce risk of HIV acquisition if exposed. PrEP has recently been positioned as an integral prevention tool to reduce HIV acquisition risk among men who have sex with men (MSM) at country-level and within global prevention strategies. Given this global scale up of PrEP, we conducted a scoping review of extant international literature documenting service related perspectives, models and lessons learnt in PrEP programming for MSM. A systematic search of literature was conducted, and restricted to English language records in the timeframe 2008 to February 2019. Eligibility criteria centered on whether studies broadly described PrEP programming and service delivery for MSM as well as health communication. Following exclusion of ineligible records and removal of duplicates, 84 records were charted and thematically analysed according to scoping review methods. Four themes emerged from the thematic analysis of data; 'PrEP service aspects, settings and staff'; 'PrEP prescriber experiences, therapeutic alliance and care planning'; 'PrEP adherence within formal service structures'; and 'Multi-disciplinary and innovative PrEP care pathways'. The review highlights the complexities in providing optimal PrEP services for MSM by mapping and illustrating the importance of understanding the informal and formal routes to PrEP use among this HIV risk population; the barriers to uptake; the requirement for the presence of a positive therapeutic alliance between patient and prescriber in supporting patient initiation and adherence to PrEP regimes; and the need for availability in different culturally and ethnically sensitive models of PrEP service delivery according to low to high risk groups within the MSM communities.

Meta-synthesis of Qualitative Research of Pre-exposure Prophylaxis (PrEP) Adherence Among Men Who Have Sex With Men (MSM)

The aim of the study was to consolidate evidence on barriers and facilitators to PrEP adherence among men who have sex with men. PubMed, Science Direct, and EBSCO host were utilized to search for relevant articles. Six articles from PubMed, published between 2010 and 2018, were reviewed. Thematic analysis was employed to synthesize findings. At the individual level, HIV susceptibility, knowledge of PrEP, and individual lifestyle affected PrEP adherence. At the organizational level, cost of PrEP and quality of PrEP services influenced adherence to PrEP. At the societal level, social stigma, financial assistance or medical insurance, and family and peer support were determinants of PrEP adherence. Facilitators included perceived high risk of HIV infection and payment assistance, while barriers included social stigma and high cost of PrEP. Social stigma and structural level factors such as payment assistance and cost of PrEP need to be examined to ensure optimal adherence to PrEP.

Disclosure of HIV Status and HIV Sexual Transmission Behaviors among HIV-Positive Black Men Who Have Sex with Men in the BROTHERS (HPTN 061) Study

We assessed whether disclosure of HIV status is significantly associated with reported HIV sexual risk behaviors among HIV positive Black/African American men who have sex with men (MSM) (Black MSM) in six cities in the USA. Participants from the BROTHERS (HIV Prevention Trials Network [HPTN 061]) study focused on assessing the feasibility and acceptability of a multifaceted HIV prevention intervention to reduce HIV infections among Black MSM enrolled between July 2009 and October 2010. All participants completed a behavioral assessment using an audio computer-assisted self-interview that included questions about HIV status disclosure, HIV sexual risk behaviors, and other behaviors. Biological samples were also collected. This analysis focused on baseline data of HIV-positive Black MSM in the HPTN 061 study. Of the 143 HIV-positive Black MSM (majority ≥ 35 years of age) included in this analysis, 58% reported disclosing their HIV status to their last male anal sex partner. Forty-three percent and 42% reported condomless insertive and receptive anal intercourse respectively with their last male partner; whereas, 17% and 18% of the sample engaged in condomless insertive and receptive anal intercourse with a serodiscordant/unknown status partner, respectively. In multivariable logistic regression models, there was no statistically significant association between HIV status disclosure and condomless insertive anal intercourse (aOR = 0.35, 95% CI 0.11, 1.08; p = 0.30), condomless receptive anal intercourse (aOR = 2.48, 95% CI 0.94, 6.52; p = 0.20), or condomless receptive anal intercourse with a serodiscordant/unknown status partner (aOR = 0.55, 95% CI 0.20, 1.49; p = 0.45). However, HIV status disclosure was significantly associated with lower odds of reporting condomless insertive anal intercourse with a serodiscordant/unknown status partner (aOR = 0.19, 95% CI 0.06, 0.68; p ≤ 0.01). Among this multi-city sample of HIV-positive Black MSM, disclosure of HIV status was common and associated with lower HIV sexual risk behaviors. These findings should motivate and guide research to develop prevention messages to increase HIV status disclosures.

Assessing determinants of pre-exposure prophylaxis (PrEP) adherence among a sample of rural Midwestern men who have sex with men (MSM)

Pre-exposure prophylaxis (PrEP) efficacy in preventing HIV among gay, bisexual, and other men who have sex with men (MSM) is dependent upon adherence. Little is known about the PrEP adherence experiences among MSM who live in rural areas of the US. This qualitative study was informed by a modified version of Straussian Grounded Theory. Thirty-four 34 rural Midwestern MSM participated in telephone interviews that assessed their PrEP adherence factors. Overall, participants adhered to the PrEP regimen, ranging from missing none to a couple of doses per month. Participants had high self-efficacy (competence) and self-reliance (autonomy) in taking PrEP daily. Participants incorporated PrEP into their already existing routines. Participants were motivated to adhere to prevent HIV acquisition and be financially responsible. All participants mentioned their PrEP provider discussed the importance of adherence with PrEP's effectiveness, but future patient-provider PrEP adherence communication varied among participants. Future PrEP adherence interventions should address counseling strategies that leverage these constructs to support pill taking. Future research should explore patient-provider conversations surrounding PrEP adherence to inform provider- and patient-level interventions.

Pre-exposure Prophylaxis Use and Medication Adherence Among Men Who Have Sex With Men: A Systematic Review of the Literature

The appropriate use of pre-exposure prophylaxis (PrEP) by men who have sex with men (MSM) can be highly effective at reducing HIV transmission. Our review examined prevalence estimates, sexual behaviors, and medication adherence among MSM PrEP users in high-income countries. Articles published between January 2008 and December 2018 were identified through Medline, Web of Science, CINAHL, and CENTRAL. The search identified 643 publications, of which 52 were included in the final synthesis. We found that PrEP initiation was not consistently associated with significant changes in sexual behavior, but some users may have risk compensated. A minority of MSM used PrEP, and they had high levels of adherence. PrEP-related stigma, side effects, and psychosocial factors lead to nonadherence. A daily routine, pill boxes, alarms/texts, and education can promote adherence. Further research is required to examine PrEP impact on sexual behavior and factors that influence adherence in high-risk MSM subpopulations.

Gay and Bisexual Men's Strategies to Maintain Daily Adherence to Their HIV Pre-exposure Prophylaxis (PrEP) Medication: Results from a Qualitative Study

Since FDA approval in 2012, HIV pre-exposure prophylaxis (PrEP) has been adopted by key populations, including gay and bisexual men (GBM), to reduce their HIV transmission risk. Given that PrEP is optimally effective when taken as prescribed, it is critical to understand the adherence strategies GBM use. We conducted one-on-one, semi-structured interviews with GBM taking PrEP in 2015-2016 (n = 103). Using thematic analysis, we identified six adherence strategies, with most participants (84.3%) utilizing multiple strategies to maintain adequate adherence: (1) integrating PrEP into part of a daily routine, (2) using a pillbox, (3) cognitive strategies/visual cues, (4) setting recurring smartphone alarms or reminders, (5) keeping medication on oneself at all times, and (6) partner or peer support for reminders and/or pill sharing. Overall, participants reported high PrEP adherence (M = 1.6 missed doses in the prior 30 days), though nearly all described missing at least one dose unintentionally in the past. Participants credited their high levels of adherence in part to the strategies they adopted. Providers working with GBM prescribed PrEP, especially patients reporting difficulties with adherence, might consider recommending any or all of the six strategies described in this study.

A Mobile Intervention to Improve Uptake of Pre-Exposure Prophylaxis for Southern Black Men Who Have Sex With Men: Protocol for Intervention Development and Pilot Randomized Controlled Trial

BACKGROUND

The uptake of pre-exposure prophylaxis (PrEP) has been slow for young black men who have sex with men (BMSM) living in the southern United States. This is a significant issue because 8 of the 10 states with the highest rates of new HIV infections are in the South. Jackson, Mississippi (MS), the site of this project, has the second highest AIDS diagnosis rate in the nation and the highest rate of HIV infection for young, urban BMSM. This study will develop and test an engaging, interactive, and cost-effective mobile messaging intervention to improve engagement in PrEP care for BMSM aged 18 to 35 years living in Jackson, MS.

OBJECTIVE

The goals of this mixed methods study are to (1) conduct qualitative interviews with young BMSM in Jackson, MS, to understand individual, community, and structural barriers affecting engagement in PrEP-related care, (2) assemble a PrEP mobile messaging intervention that includes text messages with publicly available internet content (websites and YouTube videos) that provide factual information, motivational materials, and behavioral skills related to PrEP and HIV prevention, and (3) evaluate the preliminary efficacy of the intervention in a randomized controlled study with PrEP-eligible BMSM receiving care in STI/HIV testing clinics in Jackson, MS.

METHODS

This research protocol will be conducted in 2 phases. A development phase will involve in-depth interviews (n=30) with PrEP-eligible BMSM who receive care in STI/HIV testing clinics in MS. These interviews will allow researchers to select the texted material that will be sent out during the intervention. The second phase will consist of an unblinded, small, randomized controlled trial among 66 new participants to examine the preliminary efficacy of the intervention compared with enhanced standard of care (ESC) on attendance at a PrEP services appointment (the first step in initiating PrEP care) and receipt of a PrEP prescription, based on self-report and electronic medical records. The free, publicly available material will be sent to PrEP-eligible BMSM in 8 to 16 interactive text messages over 4 weeks. Study assessments will occur at enrollment and at 4- and 16-weeks postenrollment and can be completed online or in person. All participants will be recruited from a local clinic.

RESULTS

Institutional review board approval was received on January 16, 2017, and research activities, subsequently, began in February 2018. Recruitment for the study concluded in November 2019. In total, 65 participants were randomized with 33 being assigned to the intervention and 32 to ESC. Collection of follow-up data is ongoing.

CONCLUSIONS

This PrEP mobile messaging intervention aims to increase uptake of PrEP by BMSM in the southern United States. This intervention uses interactive, tailored text messaging and appealing free Web content (publicly accessible educational websites and YouTube videos) to promote linkage to PrEP care and increase HIV preventative behaviors. A cost-effective PrEP mobile messaging intervention has great potential to improve information about PrEP, improve motivation to use PrEP, and decrease stigma and structural barriers that often prevent engagement in PrEP-related medical care.

Adherence to PrEP Among Young Men Who Have Sex With Men Participating in a Sexual Health Services Demonstration Project in Alameda County, California

BACKGROUND

Young men of color who have sex with men face a continual increase in rates of HIV infection. Pre-exposure prophylaxis (PrEP) is an important prevention method for these young men.

SETTING

The Connecting Resources for Urban Sexual Health (CRUSH) demonstration project provided sexual health services, including PrEP, to young men who have sex with men aged 18-29 years. We report on adherence and factors influencing it.

METHODS

Participants were offered HIV and sexually transmitted infection testing, prevention counseling, PrEP, and when appropriate, sexually transmitted infection treatment and postexposure prophylaxis. Participants taking PrEP had erythrocyte tenofovir diphosphate and emtricitabine levels measured through dried blood spot testing at 4, 12, and 24 weeks to estimate medication adherence. Participants also completed surveys to assess demographic and psychosocial measures.

RESULTS

From February 2014 to November 2015, CRUSH enrolled 257 participants. Ninety-three percent started PrEP, 81% of whom initiated it at their first visit. Twelve percent required postexposure prophylaxis before starting PrEP. Adherence at protective levels was initially high with 87% demonstrating levels consistent with at least 4 doses per week at week 4, compared with 77% at the 48-week follow-up. African American race, exposure to violence, and having survival needs were associated with significantly lower levels of adherence [odds ratio (OR): 0.33; confidence interval (CI): 0.11 to 0.97, P < 0.04; OR: 0.79; CI: 0.59 to 1.04, P < 0.10; OR: 0.51; CI: 0.24 to 1.05, P < 0.07].

CONCLUSIONS

Most young men who initiate PrEP adhere at levels that confer protection against HIV infection. Interventions should account for differences in life experiences, particularly addressing the structural challenges facing young African American men.

Rates of Pre-exposure Prophylaxis Use and Discontinuation Among a Large U.S. National Sample of Sexual Minority Men and Adolescents

Pre-exposure prophylaxis (PrEP) is highly effective in the prevention of HIV acquisition and was recently approved for those under 18 years of age. The primary goal of the present study was to understand the prevalence of and factors associated with PrEP use among a large sample of young and adult sexual minority men (Y/SMM). Participants came from a larger national sample of SMM. Data collected included demographics, substance use, PrEP use, and sexual risk. Participants were recruited via sexual networking/dating applications and resided in the U.S. including Puerto Rico, were at least 13 years old, self-reported being HIV-negative, and identified as male. The sample was divided into two groups: YSMM (13-24 years of age) and adult SMM (25 years of age and up). Multinomial logistic regressions examining associations with never, current, and former PrEP use were run with all variables of interest simultaneously entered into the models. Age was positively associated with both former and current PrEP use among YSMM. Additionally, YSMM who identified as gay (vs. bisexual), lived in the Northeast, Midwest, and West (vs. South), had their own health insurance (vs. those on their parent's), had recently been diagnosed with an STI, and had recently used a drug all had higher odds of being a current PrEP user compared to those that had never used PrEP. Among adult SMM, those who were older did not have higher odds of current PrEP use compared to those that had never used PrEP. Those who identified as queer (vs. gay), single, had their own or were on their partner's insurance (vs. parent's), recent condomless anal sex, recent STI diagnosis, recent drug use, and recent substance use all had higher odds of being a current PrEP user compared to those that had never used PrEP. Research is needed to address the disparities in PrEP uptake among YSMM. Interventions for PrEP access among those on their parents' insurance may also be necessary.

PrEP and sexual well-being: a qualitative study on PrEP, sexuality of MSM, and patient-provider relationships

Most new diagnoses of HIV in the United States are among men who have sex with men (MSM). Pre-exposure prophylaxis (PrEP) is a medication that mitigates risk of HIV acquisition and requires regular STI testing and prescription refills with PrEP providers. Because PrEP care monitors sexual behavior, there is a need to understand how PrEP providers approach sexual health care for MSM patients. In this study, semi-structured qualitative interviews were conducted with 20 MSM in Atlanta, Georgia with current or past prescriptions for PrEP. Data were analyzed with thematic analysis using four major steps: (1) code and codebook development, (2) assigning codes to segments of interviews, (3) code-based and comparative analysis methods, and (4) developing thematic findings. Findings from interviews about changes in sexuality while using PrEP include decreased anxiety surrounding sex, increased feelings of control over personal health, and experiencing less stigma towards sexual partners with HIV. Participants indicated needs for tailored health advice based on individual sexual preferences, sexual health care free from stereotypical assumptions, and improved access to PrEP providers identifying as gay men or who practice in LGBT-friendly settings. Study findings support a call for a gain-frame approach to sexual health in PrEP care for MSM.

Patterns and Correlates of Participant Retention in a Multi-City Pre-Exposure Prophylaxis Demonstration Project

BACKGROUND

Safe and effective use of pre-exposure prophylaxis (PrEP) depends on retention in care after initial engagement.

SETTING

The United States PrEP Demonstration Project offered daily oral tenofovir/emtricitabine to participants in San Francisco, Miami, and Washington, D.C. for 48 weeks from 2012 to 2014.

METHODS

The Demo Project participants' patterns of retention were assigned to 1 of 3 categories: early loss to follow-up (ELTF) within the first 12 weeks of the study, retention throughout the study, or intermittent retention in which missed or delayed visits resulted in gaps in medication availability. For each group, baseline characteristics were tabulated. A two-step multivariable analysis was performed.

RESULTS

Overall, 366/554 (66.1%) of enrolled participants were retained for all study visits, 127/554 (22.9%) had intermittent retention, and 61/554 (11.0%) ELTF. In multivariable analysis, Miami compared with San Francisco site was associated with ELTF rather than full retention [aOR 2.84; confidence interval (CI): 1.24 to 6.47] and also with intermittent rather than full retention (aOR 2.70; CI: 1.43 to 5.11). Younger age was associated with ELTF (aOR 1.80 for each 10-year decrement in age; CI: 1.26 to 2.57) and intermittent retention (aOR 1.47; CI: 1.17 to 1.84) compared with full retention. Factors associated with ELTF (but not intermittent retention) compared with full retention were black compared with white (aOR 3.32; CI: 1.09 to 10.16), reporting sex work (aOR 4.67; CI: 1.49 to 14.58), lack of regular employment (aOR 2.53; CI: 1.27 to 5.05), and lack of previous PrEP awareness (aOR 2.01; CI: 1.01 to 3.96).

CONCLUSIONS

Tailored interventions addressing causes and risk factors for loss from PrEP care may improve retention and consistency of PrEP use.

Barriers and Facilitators of PrEP Adherence for Young Men and Transgender Women of Color

We aimed to discover barriers and facilitators of HIV pre-exposure prophylaxis (PrEP) adherence in young men and transgender women of color who have sex with men (YMSM/TW). Short-term and sustained adherence were measured by urine tenofovir concentration and pharmacy refills, respectively. Optimal adherence was defined as having both urine tenofovir concentration consistent with dose ingestion within 48 h and pharmacy refills consistent with ≥ 4 doses per week use. Participants completed semi-structured interviews exploring adherence barriers and facilitators. Participants (n = 31) were primarily African-American (68%), mean age 22 years (SD: 1.8), and 48% had optimal adherence. Adherence barriers included stigma, health systems inaccessibility, side effects, competing stressors, and low HIV risk perception. Facilitators included social support, health system accessibility, reminders/routines, high HIV risk perception, and personal agency. Our findings identify targets for intervention to improve PrEP adherence in these populations, including augmenting health activation and improving accuracy of HIV risk perception.

Motives for choosing, switching and stopping daily or event-driven pre-exposure prophylaxis - a qualitative analysis

INTRODUCTION

In settings where both daily and event-driven pre-exposure prophylaxis (PrEP) are offered to men who have sex with men (MSM), a clear understanding of the motives to choose between the different dosing-regimens can facilitate more effective PrEP implementation. We therefore studied the motives for choosing for, switching between, and stopping daily or event-driven PrEP.

METHODS

We used data (August 2015-June 2017) from the prospective, longitudinal, open-label Amsterdam PrEP demonstration study, in which daily (dPrEP) and event-driven PrEP (edPrEP) were offered to 374 HIV-negative MSM and two transgender persons. Participants self-selected the preferred PrEP-regimen at baseline and could switch regimens at three-monthly follow-up visits. We measured motives for choosing PrEP-regimen at baseline and for switching and stopping PrEP at follow-up visits. Open- and closed-end items were combined and qualitatively analysed.

RESULTS

Choices of PrEP-regimens were determined by personal and contextual factors, involving the perceived self-efficacy concerning adherence, the risk-context, and the anticipated impact of PrEP on physical and sexual wellbeing. dPrEP was preferred because of the anticipated better adherence and the fear of side-effects relating to edPrEP re-initiations. Moreover, dPrEP was perceived to be more effective than edPrEP. Motives to choose edPrEP were the expected physical burden of dPrEP, anticipated side-effects of dPrEP, and fear to forget daily doses. Regarding the risk-context: dPrEP was preferred for unplanned and/or frequent sex, while edPrEP was chosen when risk was predictable and/or less frequent. While some chose for dPrEP to gain more sexual freedom, others chose for edPrEP to minimize sexual risk episodes. Changes in the above factors, such as changing risk patterns, changing relationships or changing physical conditions, resulted in switching regimens. Choices to stop PrEP were related to lower sexual risk, adherence issues and side-effects.

CONCLUSIONS

The great diversity of motives illustrates the importance of offering a choice of PrEP-regimens. In counselling of MSM starting PrEP, choices for PrEP-regimens may be addressed as a continuum of flexible and changeable options over time. This may help individuals choose the PrEP-regimen that best fits their current sexual context, priorities and personal capabilities and therefore will be more easily adhered to.

Dealing with pre-exposure prophylaxis-associated condom migration: changing the paradigm for men who have sex with men

The behavioural aspects of pre-exposure prophylaxis (PrEP) are challenging, particularly the issue of condom migration. Three vital questions are: (1) at the population-level, will condom migration lead to increases in non-viral sexually transmissible infections?; (2) how can clinic-based counselling best promote the dual use of condoms and PrEP?; and (3) in future PrEP trials, what are the 'best practices' that should be used to avoid type 1 and type 2 errors that arise without accounting for condom use behaviours? This communication piece addresses each question and suggests the risk of a 'PrEP only' focus to widening health disparities.

Access to HIV Pre-exposure Prophylaxis in Practice Settings: a Qualitative Study of Sexual and Gender Minority Adults' Perspectives

BACKGROUND

Sexual and gender minority (SGM) populations remain at disproportionate risk of HIV infection. Despite the effectiveness of pre-exposure prophylaxis (PrEP) in preventing HIV, PrEP uptake has been slow.

OBJECTIVE

To identify barriers and facilitators of PrEP access by examining SGM patients' experiences with accessing health care systems and engaging with providers about PrEP in a variety of practice settings.

DESIGN

Semi-structured, individual, qualitative interviews.

PARTICIPANTS

Twenty-seven sexual and gender minority adults residing in Oregon.

APPROACH

Interviews were audio-recorded, transcribed, and analyzed using thematic analysis.

KEY RESULTS

We identified three main themes. Participants described the centrality of patient-provider relationships to positive experiences around PrEP, the necessity of personally advocating to access PrEP, and the experience of system-level barriers to PrEP access. Participants also made several suggestions to improve PrEP access including improving provider engagement with SGM patients, encouraging providers to initiate conversations about PrEP, and increasing awareness of medication financial support.

CONCLUSIONS

In order to reduce HIV disparities, improving PrEP access will require additional efforts by providers and resources across health care settings to reduce barriers. Interventions to improve provider education about PrEP and provider communication skills for discussing sexual health are needed. Additionally, there should be system-level improvements to increase coordination between patients, providers, pharmacies, and payers to facilitate PrEP access and uptake.

Perspectives of US women participating in a candidate PrEP study: adherence, acceptability and future use intentions

INTRODUCTION

Limited data exist on acceptability of candidate pre-exposure prophylaxis (PrEP) regimens among US women. We evaluated PrEP experiences, attitudes and future use intentions among sexually active women who completed the US-based HIV Prevention Trials Network 069/AIDS Clinical Trials Group 5305 study.

METHODS

Women participated in the study between March 2013 and November 2015. We analysed computer-assisted self-interview (CASI) surveys among 130 women and conducted in-depth interviews among a subset of 26 women from three sites. Interviews were conducted in mid/late-2015.

RESULTS

Most women (57%) reported very good/excellent PrEP adherence on CASI, although 21% acknowledged over-reporting adherence at least some of the time. Commitment to preventing HIV infection, a sense of ownership of the study, and keeping pills stored in a visible location facilitated adherence. Adherence barriers included "simply forgetting" and being away from home. Most women interviewed did not intend to use PrEP in the future because of lack of perceived need due to their own (as opposed to their partners') low-risk behaviour and concerns about affordability - but not because of side effects or other characteristics of the regimens.

DISCUSSION

Improving HIV prevention options for US women will require access to affordable PrEP as well as expanding women's understanding of relationship- and community-level factors that increase their risk of acquiring HIV.

"Little Tablets of Gold": An Examination of the Psychological and Social Dimensions of PrEP Among LGBTQ Communities

There are significant psychological, social, and cultural dimensions to the HIV epidemic in the United States, especially among lesbian, gay, bisexual, transgender, and queer (LGBTQ) communities. Biomedical HIV treatment has been shown to impact these dimensions. However, there is little understanding of the real-world psychosocial and sociocultural effects of the latest biomedical HIV prevention strategy, HIV pre-exposure prophylaxis (PrEP). This study explored the psychosocial and sociocultural dimensions of PrEP use among LGBTQ adults. We interviewed 23 LGBTQ adults who were current or former users of PrEP. Results included that PrEP users' experiences were shaped by multiple forms of stigma. Participants were highly motivated to challenge PrEP stigma and to support PrEP use among other community members. Lastly, participants described positive impacts on their individual well-being and their sexual partnerships. Findings suggest that PrEP has significant impacts beyond biomedical outcomes for both the individuals who use PrEP and their communities.

Clinical exigencies, psychosocial realities: negotiating HIV pre-exposure prophylaxis beyond the cascade among gay, bisexual and other men who have sex with men in Canada

INTRODUCTION

Notwithstanding the efficacy of oral pre-exposure prophylaxis (PrEP) in clinical trials, a number of obstacles exist to achieving population-level impact among gay, bisexual and other men who have sex with men (GBM). However, few studies have explored the subjective experiences of GBM PrEP users and non-users in the community, outside of clinical trials. The objectives of this study were to explore GBM's experiences of considering, accessing and using (or not using) PrEP, and to understand emerging sexual health, social and community issues among GBM in the PrEP era.

METHODS

From October 2015 to March 2016, we purposively sampled PrEP-naïve and PrEP-experienced GBM from community organizations and health centres in Toronto, Canada. In-depth, 45- to 90-minute semi-structured interviews explored PrEP perspectives and decision-making, access, initiation, use over time, sexual practices and psychosocial considerations. Interviews were recorded, transcribed verbatim, uploaded into NVIVO, reviewed using thematic analysis and then contrasted with the PrEP cascade.

RESULTS

Participants included PrEP users (n = 15) and non-users (n = 14) (mean age = 36.7 years; SD = 8.2), largely gay-identified (86.2%), cisgender male (89.7%) and white (79.3%). Themes indicate not only correspondences, but also limitations of the PrEP cascade by complicating a user/non-user binary and challenging the unilateral presupposition that HIV risk perception leads to PrEP acceptance. Findings further call into question assumptions of a linear stage progression and retention in care as a universal endpoint, instead revealing alternate trajectories of seasonal or intermittent PrEP use and, for some, an end goal of terminating PrEP. GBM's narratives also revealed potent psychological/affective experiences of untethering sex from HIV anxiety; multifaceted PrEP stigma; and challenges to sexual norms and practices that complicate existing behavioural prevention strategies and sexual and social relationships.

CONCLUSIONS

An expanded PrEP cascade should consider alternate trajectories of use based on dynamic relationships and behavioural risks that may call for seasonal or intermittent use; systemic barriers in access to and sustaining PrEP; and multiple end goals including PrEP maintenance and discontinuation. Incorporating GBM's lived experiences, evolving preferences, and psychosocial and community-level challenges into PrEP implementation models, rather than a circumscribed biomedical approach, may more effectively support HIV prevention and GBM's broader sexual and psychological health.

The Role of Social Relationships in PrEP Uptake and Use Among Transgender Women and Men Who Have Sex with Men

Qualitative studies suggest that social relationships play an important role in HIV pre-exposure prophylaxis (PrEP) use, but there have been few quantitative assessments of the role of social relationships in PrEP uptake or adherence. We examined the association between disclosure of study participation or LGBT identity and PrEP use in the 1603 HIV-negative participants enrolled in the iPrEx OLE study. We also evaluated the association between LGBT social group involvement and PrEP use. Study participation disclosure to parents and LGBT identity disclosure to anyone in a participant's social network were associated with greater PrEP uptake. Study participation disclosure to partners was associated with higher probability of having protective PrEP drug concentrations compared [risk difference 0.15 95% CI (0.01, 0.30)]. For each additional type of LGBT organization a participant was involved in, the probability of PrEP uptake and having protective drug concentrations increased by 0.04 [95% CI (0.03, 0.06)] and 0.04 (95% CI (0.02, 0.07)] respectively. Overall, social context was associated with PrEP use in iPrEx OLE, and should be taken into consideration when designing future PrEP implementation programs.

Temporal Fluctuations in Behavior, Perceived HIV Risk, and Willingness to Use Pre-Exposure Prophylaxis (PrEP)

Individual perceptions of HIV risk influence willingness to use pre-exposure prophylaxis (PrEP) for HIV prevention. Among men who have sex with men (MSM) and male sex workers (MSWs), temporal or episodic changes in risk behavior may influence perceived risk and PrEP acceptability over time. We investigated fluctuations in perceived HIV risk and PrEP acceptability, comparing MSWs against MSM who do not engage in sex work. We conducted 8 focus groups (n = 38) and 56 individual interviews among MSM and MSWs in Providence, RI. Perceived HIV risk shaped willingness to use PrEP among both MSWs and MSM who did not engage in sex work, and risk perceptions changed over time depending on behavior. For MSWs, perceived risk cycled according to patterns of substance use and sex work activity. These cycles yielded an "access-interest paradox": an inverse relationship between willingness to use and ability to access PrEP. MSM who did not engage in sex work also reported temporal shifts in risk behavior, perceived risk, and willingness to use PrEP, but changes were unrelated to access. MSM attributed fluctuations to seasonal changes, vacations, partnerships, behavioral "phases," and episodic alcohol or drug use. Efforts to implement PrEP among MSM and street-based MSWs should address temporal changes in willingness to use PrEP, which are linked to perceived risk. Among MSWs, confronting the access-interest paradox may require intensive outreach during high-risk times and efforts to address low perceived risk during times of reduced sex work.

Smartphone-Based Contingency Management Intervention to Improve Pre-Exposure Prophylaxis Adherence: Pilot Trial

Background

Pre-exposure prophylaxis (PrEP) provides a strong preventative benefit to individuals at risk for HIV. While PrEP adherence is highly correlated with its efficacy, adherence rates are variable both across and within persons.

Objective

The objective of this study was to develop and pilot-test a smartphone-based intervention, known as mSMART, that targets PrEP adherence. mSMART provides contingency management in the form of monetary incentives for daily PrEP adherence based on a real-time adherence assessment using a camera-based medication event-monitoring tool as well as medication reminders, PrEP education, individualized behavioral strategies to address PrEP adherence barriers, and medication adherence feedback.

Methods

This was a 4-week open-label, phase I trial in a community sample of young men who have sex with men already on PrEP (N=10).

Results

Although adherence composite scores corresponding to PrEP biomarkers indicated that 90% (9/10) of the sample already had an acceptable baseline adherence in the protective range, by the end of the 4-week period, the scores improved for 30% (3/10) of the sample—adherence did not worsen for any participants. Participants reported mean PrEP adherence rates of 91% via daily entries in mSMART. At the end of the 4-week period, participants indicated acceptable ratings of satisfaction, usability, and willingness to recommend mSMART to others. There were no technical difficulties associated with smartphone compatibility, user misunderstandings about mSMART features that interfered with daily use, or study attrition.

Conclusions

This study is the first to apply contingency management to PrEP adherence. Findings indicated that mSMART is feasible and acceptable. Such an adherence intervention administered via a user-friendly smartphone app can allow for widespread dissemination. Future efficacy trials are needed.

Stigma and Shame Experiences by MSM Who Take PrEP for HIV Prevention: A Qualitative Study

Pre-exposure prophylaxis (PrEP) uptake has been extremely low among key groups. PrEP-related stigma and shaming are potential barriers to uptake and retention in PrEP programs. There is a lack of literature describing PrEP stigma. In order to fill this gap, we recruited online 43 HIV-negative Men who have Sex with Men (MSM) who use PrEP. Semistructured interviews were conducted to explore their perceptions and experience of stigma related to PrEP use. Data were analyzed using Strauss and Corbin's grounded theory and constant comparison techniques to enhance understanding of the lived experiences of MSM who use PrEP. The participants experienced PrEP stigma as rejection by potential/actual partners, stereotypes of promiscuity or chemsex, and labeling of both the user and the medication. They connected PrEP stigma with HIV stigma, generational differences, moralization of condom use, and inability to embrace one's own sexuality. These findings point to a need to develop tailored interventions to address PrEP-related stigma and shaming for individuals, health-care professionals, and the MSM community-at-large.

Exploring the Use of Pre-exposure Prophylaxis (PrEP) for HIV Prevention Among High-Risk People Who Use Drugs in Treatment

Introduction: Despite unequivocal evidence supporting the use of pre-exposure prophylaxis (PrEP), its scale-up has been gradual overall, and nearly absent among people who use drugs (PWUD). In the present study, we implemented the use of PrEP, as a part of an integrated HIV prevention approach, and explored the experiences and attitudes related to PrEP use among PWUD.

Methods: Between September 2016 and July 2017, we recruited 40 HIV-uninfected, methadone-maintained people, who reported HIV-risk behaviors, and were currently taking PrEP. We conducted both quantitative and in-depth semi-structured qualitative interviews that primarily focused on experiences, attitudes, acceptability, disclosure status, risk compensation-related attitudes, and barriers related to PrEP adherence.

Results: Results showed that participants were highly satisfied and perceived PrEP as valuable and acceptable for HIV prevention. Participants reported high adherence to PrEP. The most highly endorsed facilitators to PrEP adherence were use of memory aids, no out-of-pocket cost, perceived benefit, and support from social network. The barriers to adherence included side-effects, stigmatization, requirement of daily dosing, and accessibility of PrEP services. Additionally, participants expressed disagreement with the overall risk compensation-related attitudes (i.e., decreased personal concern about engaging in HIV risk behavior due to their perception that PrEP is now fully protecting them from contracting HIV) and indicated no increased engagement in risk behaviors while on PrEP.

Conclusions: The results from the current study provide preliminary evidence supporting the successful integration of PrEP within the substance abuse treatment setting, where high risk PWUD are concentrated.

Promoting positive condom use experiences among young black MSM: a randomized controlled trial of a brief, clinic-based intervention

The aim of this study is to determine, among young Black men who have sex with men (YBMSM), the 12-month efficacy of a single-session, clinic-based intervention promoting condom use to enhance sexual pleasure (purpose 1) and the use of condoms from the start-to-finish of anal sex (purpose 2). A pre-test, post-test randomized controlled trial was conducted, using a 12-month period of follow-up observation, in STI clinics. Data from 394 YBMSM completing baseline and 12-month follow-up assessments were analyzed. The experimental condition comprised a one-to-one, interactive program (Focus on the Future) designed for tailored delivery. Regarding study purpose 1, in an age-adjusted linear regression model for 277 HIV-uninfected men, there was a significant effect of the intervention (Beta=0.13, P =0.036) relative to more favorable sexual experiences when using condoms. Regarding study purpose 2, in an adjusted logistic regression model, for HIV-uninfected men, there was a significant effect of the intervention (AOR=0.54, P =0.048) relative to using condoms from start-to-finish of anal sex. Significant effects for HIV-infected men were not observed. A small, but non-significant, effect was observed relative to men's self-report of always using condoms. This single-session program may be a valuable counseling tool for use in conjunction with pre-exposure prophylaxis-related care for HIV-uninfected YBMSM.

Optimizing adherence in HIV prevention product trials: Development and psychometric evaluation of simple tools for screening and adherence counseling

Background

Low adherence in recent HIV prevention clinical trials highlights the need to better understand, measure, and support product use within clinical trials. Conventional self-reported adherence instruments within HIV prevention trials, often relying on single-item questions, have proven ineffective. While objective adherence measures are desirable, none currently exist that apply to both active and placebo arms. Scales are composed of multiple items in the form of questions or statements that, when combined, measure a more complex construct that may not be directly observable. When psychometrically validated, such measures may better assess the multiple factors contributing to adherence/non-adherence. This study aimed to develop and psychometrically evaluate tools to screen and monitor trial participants’ adherence to HIV prevention products within the context of clinical trial research.

Methods and findings

Based on an extensive literature review and conceptual framework, we identified and refined 86 items assessing potential predictors of adherence and 48 items assessing adherence experience. A structured survey, including adherence items and other variables, was administered to former ASPIRE and Ring Study participants and similar non-trial participants (n = 709). We conducted exploratory factor analyses (EFA) to identify a reduced set of constructs and items that could be used at screening to predict potential adherence, and at follow-up to monitor and intervene on adherence. We examined associations with other variables to assess content and construct validity. The EFA of screener items resulted in a 6-factor solution with acceptable to very good internal reliability (α: .62-.84). Similar to our conceptual framework, factors represent trial-related commitment (Distrust of Research and Commitment to Research); alignment with trial requirements (Visit Adherence and Trial Incompatibility); Belief in Trial Benefits and Partner Disclosure. The EFA on monitoring items resulted in 4 Product-specific factors that represent Vaginal Ring Doubts, Vaginal Ring Benefits, Ring Removal, and Side Effects with good to very good internal reliability (α = .71-.82). Evidence of content and construct validity was found; relationship to social desirability bias was examined.

Conclusions

These scales are easy and inexpensive to administer, available in several languages, and are applicable regardless of randomization. Once validated prospectively, they could (1) screen for propensity to adhere, (2) target adherence support/counselling, and (3) complement biomarker measures in determining true efficacy of the experimental product.

Sex, PrEP, and Stigma: Experiences with HIV Pre-exposure Prophylaxis Among New York City MSM Participating in the HPTN 067/ADAPT Study

The HPTN 067/Alternative Dosing to Augment Pre-Exposure Prophylaxis Pill Taking (ADAPT) study evaluated daily and non-daily dosing schedules for oral pre-exposure prophylaxis (PrEP) to prevent HIV. A qualitative sub-study including focus groups and in-depth interviews was conducted among men who have sex with men participating in New York City to understand their experience with PrEP and study dosing schedules. The 37 sub-study participants were 68% black, 11% white, and 8% Asian; 27% were of Hispanic/Latino ethnicity. Mean age was 34 years. Themes resulting from qualitative analysis include: PrEP is a significant advance for HIV prevention; non-daily dosing of PrEP is congruent with HIV risk; and pervasive stigma connected to HIV and risk behavior is a barrier to PrEP adherence, especially for non-daily dosing schedules. The findings underscore how PrEP intersects with other HIV prevention practices and highlight the need to understand and address multidimensional stigma related to PrEP use.

A Global Estimate of the Acceptability of Pre-exposure Prophylaxis for HIV Among Men Who have Sex with Men: A Systematic Review and Meta-analysis

Pre-exposure prophylaxis (PrEP) is a new biomedical intervention for HIV prevention. This study systematically reviews the acceptability of PrEP among men who have sex with men (MSM) worldwide. We searched major English databases to identify English-language articles published between July 2007 and July 2016, which reported the acceptability of PrEP and associated population characteristics. Meta-analysis was conducted to estimate a pooled acceptability, and meta-regression and subgroup analysis were used to analyse heterogeneities. The estimated acceptance from included sixty-eight articles was 57.8% (95% confidence internal 52.4-63.1%). MSM who were younger (4/5 studies, range of adjusted odds ratio (aOR) = 1.39-3.47), better educated (aOR = 1.49-7.70), wealthier (aOR = 1.31-13.03) and previously aware of PrEP (aOR = 1.33-3.30) showed significantly higher acceptance. Male sex workers (84.0% [26.3-98.7%] were more likely to accept PrEP than general MSM. Self-perceived low efficacy, concern about side effects, adherence, affordability, and stigma were main barriers. This review identifies a moderate acceptability of PrEP in MSM. Efficacy, perception of HIV risk and experienced stigma determine its acceptance.

The Use of Online Posts to Identify Barriers to and Facilitators of HIV Pre-exposure Prophylaxis (PrEP) Among Men Who Have Sex with Men: A Comparison to a Systematic Review of the Peer-Reviewed Literature

Pre-exposure prophylaxis (PrEP) remains an under-utilized HIV prevention tool among men who have sex with men (MSM). To more comprehensively elucidate barriers and facilitators to PrEP use among US MSM, we conducted a systematic review of peer-reviewed published articles and content analysis of online posts about PrEP. We searched peer-reviewed databases (Medline, Web of Science, Google Scholar) using MESH headings and keywords about PrEP and/or HIV prevention from 2005 to 2015. We included original studies among MSM in the US that reported on barriers, facilitators, or other factors related to PrEP use. We also searched online posts and associated comments (news articles, opinion pieces, blogs and other social media posts) in diverse venues (Facebook, Slate Outward, Huffington Post Gay Voices, Queerty, and My PrEP Experience blog) to identify posts about PrEP. We used content analysis to identify themes and compare potential differences between the peer-reviewed literature and online posts. We identified 25 peer-reviewed articles and 28 online posts meeting inclusion criteria. We identified 48 unique barriers and 46 facilitators to using PrEP. These 94 themes fit into six overarching categories: (1) access (n = 14), (2) attitudes/beliefs (n = 24), (3) attributes of PrEP (n = 13), (4) behaviors (n = 11), (5) sociodemographic characteristics (n = 8), and (6) social network (n = 6). In all categories, analysis of online posts resulted in identification of a greater number of unique themes. Thirty-eight themes were identified in the online posts that were not identified in the peer-reviewed literature. We identified barriers and facilitators to PrEP in online posts that were not identified in a systematic review of the peer-reviewed literature. By incorporating data both from a systematic review of peer-reviewed articles and from online posts, we have identified salient and novel information about barriers to and facilitators of PrEP use. Traditional research approaches may not comprehensively capture current factors important for designing and implementing PrEP related interventions.

Brief Participant-Centered Convergence Interviews Integrate Self-Reports, Product Returns, and Pharmacokinetic Results to Improve Adherence Measurement in MTN-017

MTN-017 compared the safety and acceptability of daily oral emtricitabine/tenofovir disoproxil fumarate, daily reduced-glycerin 1% tenofovir gel applied rectally, and the same gel applied before and after receptive anal intercourse. The Data Convergence Interview (DCI) and the Pharmacokinetic Data Convergence Interview (PK-DCI) were brief, collaborative interactions conducted with participants during adherence counseling sessions to improve accurate measurement of adherence to study product use. DCIs converged data from product return counts and participants' responses to daily text messages. PK-DCIs, conducted 4 weeks later, converged results of the DCI with PK from the corresponding period. CIs were easily incorporated into adherence counseling sessions, increased the accuracy of adherence data, and provided valuable context to data on product use. Participants were readily engaged in the interviews but, if they felt confronted, provided more guarded responses. As such, how these CIs are conducted is critical to engage participants, even those with poor adherence, to openly discuss challenges with product use.

Factors Supporting and Hindering Adherence to Rectal Microbicide Gel Use with Receptive Anal Intercourse in a Phase 2 Trial

Adherence to product use in biomedical HIV prevention trials is essential to success. In MTN-017, a Phase 2 rectal microbicide gel trial, participants discussed applicator-inserted gel use in the context of receptive anal intercourse (RAI) with adherence counselors. We analyzed counseling session data to identify barriers to and facilitators of gel use for 26 participants in the United States who used gel with RAI as their first of three study regimens. The most common barriers were finding the gel application process cumbersome, physical discomfort after applying gel, difficulty with BAT-24 dosage regimen, and negative effects of gel on sex. The most common facilitators were incorporating gel use into routines, using gel in anticipation of sex, carrying gel when going out, reminders received via short message service, and ease of gel use. These findings can inform product development and future adherence counseling interventions for rectal gel trials to improve adherence outcomes.

Risk, safety and sex among male PrEP users: time for a new understanding

Recent advances in biomedical HIV prevention have led to optimistic projections of a dramatic worldwide reduction of new infections by 2030. This optimism is counterbalanced by concerns that the protective benefits of one such technology, HIV pre-exposure prophylaxis (PrEP), may be negated by increases in other behaviours that offset these benefits (risk compensation). To contribute to a deeper understanding of concepts of safety and risk in the context of HIV PrEP, we draw on the narrative accounts of 61 male PrEP users who participated in the inaugural PrEP demonstration project: the iPrEx open-label extension study. We conducted in-depth interviews with a purposeful sample of iPrEx participants. Overall, participants did not report significant changes to their sexual practices once they had begun taking PrEP. Rather, participants reported experiencing a sense of relief or reprieve from HIV-related stress. This unburdening of fear did not necessarily lead to condomless sex. Instead, men expressed feeling a sense of security and less free-floating fear of HIV. We contend that no longer living under the threat of HIV is a significant benefit that has not been adequately explored in HIV prevention research.

Importance of Risk Perception: Predictors of PrEP Acceptance Among Thai MSM and TG Women at a Community-Based Health Service

BACKGROUND

HIV prevalence among Thai men who have sex with men (MSM) and transgender women (TG) are 9.15% and 11.8%, respectively, compared with 1.1% in the general population. To better understand early adopters of pre-exposure prophylaxis (PrEP) in Thailand, we analyzed biobehavioral and sociodemographic characteristics of PrEP-eligible MSM and TG.

SETTING

Four Thai urban community clinics between October 2015 and February 2016.

METHODS

Sociodemographics, HIV risk characteristics, and PrEP knowledge and attitudes were analyzed in association with PrEP initiation among eligible Thai MSM and TG. Adjusted analysis explored factors associated with PrEP acceptance. We then analyzed HIV risk perception, which was strongly associated with PrEP initiation.

RESULTS

Of 297 participants, 55% accepted PrEP (48% of MSM, 54% of TG). Perceived HIV risk levels were associated with PrEP acceptance [odds ratio (OR): 4.3; 95% confidence interval (95% CI): 1.5 to 12.2. OR: 6.3; 95% CI: 2.1 to 19.0. OR: 14.7; 95% CI: 3.9 to 55.1; for minimal, moderate, and high perceived risks, respectively]. HIV risk perception was associated with previous HIV testing (OR: 2.2; 95% CI: 1.4 to 3.5); inconsistent condom use (OR: 1.8; 95% CI: 1.1 to 2.9); amphetamine use in the past 6 months (OR: 3.1; 95% CI: 1.1 to 8.6); and uncertainty in the sexually transmitted infection history (OR: 2.3; 95% CI: 1.4 to 3.7). Approximately half of those who reported either inconsistent condom use (46%), multiple partners (50%), group sex (48%), or had baseline bacterial sexually transmitted infection (48%) perceived themselves as having no or mild HIV risk.

CONCLUSIONS

HIV risk perception plays an important role in PrEP acceptance. Perception does not consistently reflect actual risk. It is therefore critical to assess a client's risk perception and provide education about HIV risk factors that will improve the accuracy of perceived HIV risk.
