A Review of Approaches Used to Increase Awareness of Pre-exposure Prophylaxis (PrEP) in the United States

Understanding PrEP Contemplation Among Black Women: Insights from a Qualitative Analysis

BACKGROUND

The lack of engagement and use of pre-exposure prophylaxis (PrEP) among Black women in the Southern United States is an enduring health disparity. Guided by an integrated theoretical framework and the PrEP Cascade, this qualitative inquiry aimed to explore Black women's motivation and decision-making regarding PrEP engagement and identify strategies to enhance PrEP messaging and uptake for those with indication(s) for PrEP use.

MATERIALS AND METHODS

Twelve semi-structured Zoom interviews were conducted between February 2020 and March 2022. Participants were sampled from a larger pool in an online survey study about factors associated with PrEP uptake among Black women. Interviews explored whether women started PrEP (or not) within 3 months after learning about PrEP in the survey and explored their reasoning. Data analysis included quantitative descriptive statistics and directed content analysis.

RESULTS

None of the 12 women had started PrEP at the time of the interview. Two were in discussions with their provider about PrEP (stage 3: PrEParation), and one intended to initiate PrEP within the next 3 months (i.e., thinking about it). Two main themes emerged as their reasons for not starting PrEP: current relationship status and PrEP information (awareness, knowledge, and literacy). Participants expressed a lack of trust in PrEP due to insufficient information while anticipated challenges in obtaining PrEP included cost and the patient-provider relationship (engagement and communication).

CONCLUSION

The findings highlight missed opportunities to improve PrEP use among Black women within the PrEP contemplation phase, emphasizing the need for improved PrEP messaging and tailored PrEP programs and/or interventions for this group.

Pre-Exposure Prophylaxis Awareness and Demand Creation: Overlooked Populations and Opportunities to Move Forward

BACKGROUND

Pre-exposure prophylaxis (PrEP) for HIV prevention has been available since 2012, but uptake remains disappointing and inequitable. Furthermore, there is little evidence on the effectiveness of interventions to increase PrEP demand among priority populations in the United States. The objectives of this article were to describe how consumer perceptions of PrEP vary by distinct population groups and identify gaps in PrEP awareness, knowledge, and interest.

METHODS

We synthesized evidence-based interventions to improve demand for PrEP in populations heavily burdened by HIV. The focus centered on consumer factors, how people's awareness of PrEP, especially people who are likely to benefit, influences PrEP uptake.

RESULTS

Awareness and equity in PrEP use among vulnerable populations in the United States remain low because of both demand-side obstacles and accessibility challenges. Designing an effective package of interventions to increase demand for PrEP involves integrating strategies that address awareness, knowledge, interest/motivation, and access.

CONCLUSIONS

The underutilization of PrEP among the 1.2 million individuals who could benefit from it highlights the need for effective demand creation to reduce disparities. To effectively increase awareness of the benefits of PrEP requires consideration of the characteristics of the target population and the structural inequalities that contribute to PrEP-related disparities. Demand creation activities can increase awareness, correct misconceptions, provide knowledge, and help people decide whether PrEP is a good fit for them. The utilization of implementation science frameworks is essential to address demand generation and supply-side barriers to PrEP use.

A Qualitative Study Exploring How the Perspectives and Experiences of Cisgender Black Women Inform Their Readiness to Consider Pre-Exposure Prophylaxis for HIV Prevention

Attention to increasing pre-exposure prophylaxis (PrEP) use among cisgender Black women (CBW) in the southern United States (U.S.) is necessary to achieve national 2030 Ending the HIV Epidemic (EHE) goals. Qualitative exploration of CBW's readiness to use PrEP is necessary to discern whether practical solutions to addressing PrEP uptake within this HIV-vulnerable population are feasible. Focus group discussions (n = 5) and key informant interviews (n = 3) in two EHE jurisdictions in Houston and Austin, Texas were used to explore how perspectives and lived experiences may serve as facilitators and/or barriers to PrEP readiness among 20 CBW. Codes highlighted facilitators and barriers to PrEP readiness. Facilitators involved positive experiences with the healthcare system, high perceived HIV vulnerability, and prioritizing PrEP as self-care. Barriers encompassed concerns with sexual relationship dynamics, mental health implications, and access to humane treatment within the healthcare system. High perceived vulnerability of HIV acquisition is related to an awareness that CBW may not know the entirety of their partner's sexual activities. Findings indicate precursors of PrEP readiness and challenge the notion that CBW have low perceived vulnerability of acquiring HIV.

Changes in HIV preexposure prophylaxis awareness and use among men who inject drugs who have sex with men by sexual identity in 19 US urban areas

BACKGROUND

Men who inject drugs who have sex with men (MWIDSM) may acquire HIV through injecting drugs or sex. Interventions to increase awareness of HIV preexposure prophylaxis (PrEP) have focused on gay/bisexual MSM and may not be reaching heterosexual-identifying men or people who inject drugs (PWID). We explored changes in PrEP awareness and use among MWIDSM from 2018 to 2022 by sexual identity.

METHODS

We used data from the 2018 and 2022 National HIV Behavioral Surveillance among PWID recruited via respondent-driven sampling in 19 urban areas in the US. We examined changes in PrEP awareness and use over time by sexual identity among HIV-negative men who inject drugs and who had sex with another man in the past 12 months using log-linked Poisson regression models with robust standard errors with an interaction term between year and sexual identity.

RESULTS

Among 758 HIV-negative MWIDSM (463 in 2018; 295 in 2022), nearly all sample participants were likely indicated for PrEP (94.2 and 92.9%, respectively). PrEP awareness increased from 2018 to 2022 among gay/bisexual-identifying MWIDSM [45.5 to 65.5%; aPR = 1.49, 95% confidence interval (95% CI) = 1.30-1.70] but remained stable for heterosexual-identifying MWIDSM (39.4 to 40.8%; aPR = 1.01, 95% CI 0.75-1.36). PrEP use remained low among all MWIDSM (2.5 to 7.7%, among heterosexually identifying; 15.3 to 10.2% among gay/bisexual-identifying).

CONCLUSION

PrEP awareness increased among gay/bisexual-identifying MWIDSM but not among heterosexual-identifying. PrEP use was low for all MWIDSM. Public health initiatives catered to MWIDSM should focus on improved campaigns and expanding PrEP accessibility in existing healthcare, harm reduction, and social services.

A Review of Studies on HIV Pre-Exposure Prophylaxis in Community Pharmacies in States with Restrictive Pharmacist Prescription Authority in the United States

Community pharmacies have unparalleled potential to increase access to pre-exposure prophylaxis medications (PrEP) for HIV prevention; however, only 17 out of 50 states in the United States have statewide authority for pharmacists to provide PrEP at community pharmacies. Few studies have reported on how pharmacists overcome the legislative barrier and provide PrEP services in restrictive pharmacy prescription states. The objective of this article is to identify the existing primary literature describing pharmacist PrEP services in the community in states with restrictive prescription authority.

METHODS

A systemic literature review was conducted to identify the primary literature that involved community pharmacy service and PrEP conducted in states that do not have expanded pharmacist prescriptive authority between 2000 to 2024.

RESULTS

Ten publications were identified, describing nine studies, including four interview and survey studies, three intervention reports, and two ongoing clinical trials. None of these studies have a control group. Most pharmacists provide PrEP services in the community through a collaborative practice agreement with a primary care provider.

CONCLUSIONS

Future clinical studies with randomized controlled designs are required to test novel strategies in the education and implementation of pharmacy-led PrEP services in a community pharmacy setting to increase PrEP access.

Examining the Effects of PrEP Use on Sexual Behaviors and Sexually Transmitted Infections Among Chinese Men who have Sex with Men: A Cross-Sectional Study

Men who have sex with men (MSM) is a high-risk population for HIV and sexually transmitted infections (STIs). Pre-exposure prophylaxis (PrEP) is effective in HIV prevention. This study aims to examine the differences in sexual behaviors, STI prevalence and HIV/STI testing across subgroups of MSM with various PrEP use. Data were collected via a cross-sectional survey in an MSM community in Xi'an, Shaanxi, from 2022.01 to 2022.09. Participants were categorized as 'PrEP-naïve and unwilling to use', 'PrEP-naïve but willing to use', and 'current or former PrEP users'. Shannon index was used to assess sexual act diversity and multivariate logistic regression analyzed factors associated with PrEP use. Of the 1,131 MSM participants, 23.52% were PrEP-naïve and unwilling, 64.98% were PrEP-naïve but willing, and 11.49% were current or former PrEP users. The PrEP-naïve but willing group had the highest recent STI testing rates at 73.06% and showed greater sexual act diversity (Shannon index 1.61). This group also had the highest syphilis rates (7.49% vs. 6.47% and2.54%, p < 0.01). Younger age (18-30: OR = 0.39 (0.18-0.85); 31-40: OR = 0.43 (0.20-0.96)) and lower education (high school/vocational: OR = 0.15 (0.04-0.58); associate degree: OR = 0.21 (0.06-0.71)) were factors that negatively influenced PrEP use. Current or former PrEP users had the highest oropharyngeal gonorrhea (14.39% vs. 9.68% and 5.80%, p < 0.01) and overall gonorrhea rates (20.86% vs. 17.17% and 8.37%, p < 0.001). 'PrEP-naïve but willing' participants consistently demonstrated high-risk sexual behavior, increased STI testing, and more diverse sexual acts, whereas PrEP users had the highest STI prevalence.

Pre-Exposure Prophylaxis and HIV Prevention Among Key Populations in Nigeria

Background and Objective

The discovery of innovative pharmacological preventative measures in Human Immunodeficiency Virus transmission has boosted optimism in the successful control of HIV/AIDS with the objective of eradication and the end of the epidemic. Hence, assessing the effect of pre-exposure prophylaxis (PrEP) on HIV prevention among key populations (KPs) is imperative in advancing the conversation on ending HIV/AIDs.

Methods

This was a cross-sectional study using data from KPs (female sex workers (FSWs), men who have sex with men (MSM), and people who inject drugs (PWIDs) enrolled in Heartland Alliance Ltd/GTE One Stop Shops (OSS) between May 2019 and April 2023 in the six selected Nigerian states (Lagos, Bayelsa, Cross River, Akwa Ibom, Jigawa, and Niger). Data were cleaned in a spreadsheet and analyzed using IBM-SPSS version 28.0. Descriptive statistics, including frequency and percentage calculations, were conducted to analyze the dataset. Additionally, cross-tabulation analysis was performed, with a significance level set at 0.05, to explore relationships between variables.

Results

The study population comprised 13,580 participants, with 56.1% female. In all, 43.9% were aged 18-35 and 97.3% were single. Among the three KPs examined, FSW was the largest subgroup (50.8%), followed by MSM (28.1%) and PWID (21.1%). Most participants had been on PrEP for 0-3 months (87.8%), and PrEP was initiated for 81.6% due to high-risk sexual behaviors and 9.9% for serodiscordant relationship reasons. Most of them were enrolled in community healthcare settings (97.0%). The results showed that 99.9% remained HIV negative, while only two (0.01%) were seroconverted while on PrEP. The HIV-positive cases did not complete one-month PreP treatment, comprising an FSW and a PWID. Recent HIV contact or poor compliance with PrEP medication are two possible causes of seroconversion.

Conclusion and Global Health Implications

The findings underscore the significance of integrating PrEP into a comprehensive HIV prevention approach, including newer molecules that will improve adherence and the necessity of ongoing monitoring and support for PrEP users. With these insights, there can be an advocacy for promoting PrEP among the KPs as a vital component of Nigeria's HIV prevention strategy.

Structural vulnerabilities and PrEP awareness among Boston heterosexuals and people who inject drugs at risk for HIV: findings from 2018 to 2019 cycles from the Boston, MA site of the NHBS

Little is known about biopsychosocial factors relating to pre-exposure prophylaxis (PrEP) awareness among people with either heterosexual or injection drug use HIV risk behaviors. Participants engaged in vaginal/anal sex with a person of the opposite sex (N = 515) or were people who injected drugs (PWID; N = 451) in the past 12 months from 2018-2019 in Boston, MA. We examined associations between PrEP awareness and: homelessness; perceived HIV-related stigma; country of birth; bacterial STDs, chlamydia, and/or gonorrhea in the past 12 months, lifetime hepatitis C virus (HCV) infection, sexual orientation, and poverty. More PWID (36.8%) were aware of PrEP than people with heterosexual HIV risk (28%; p = .001). Among people with heterosexual risk, homelessness (aOR = 1.99, p = .003), and among PWID: homelessness (aOR = 2.11, p = .032); bacterial STD (aOR = 2.96, p = .012); chlamydia (aOR = 6.14, p = .008); and HCV (aOR = 2.40, p < .001) were associated with increased likelihood of PrEP awareness. In the combined sample: homelessness (aOR = 2.25, p < .001); HCV (aOR = 2.18, p < .001); identifying as homosexual (aOR = 3.71, p = .036); and bisexual (aOR = 1.55, p = .016) were each associated with PrEP awareness. Although having an STD, HCV, identifying as homosexual or bisexual, and experiencing homelessness were associated with increased PrEP awareness, most participants were unaware of PrEP. Efforts to increase PrEP awareness could engage PWID and heterosexual HIV risk behavior.

Pre-exposure prophylaxis access, uptake and usage by young people: a systematic review of barriers and facilitators

Background

Young people's sexual health decision-making, including decisions to access and adhere to HIV prevention strategies such as Pre-Exposure Prophylaxis (PrEP), are influenced by a range of internal and external factors. Synthesizing these factors is essential to guide the development of youth-focused PrEP health promotion strategies to contribute to international goals of ending HIV transmission.

Objective

To understand the individual, interpersonal, sociocultural and systemic barriers and facilitators to PrEP access, uptake and use experienced by young people 24 years and younger.

Design

A systematic review that adhered to the Preferred Reporting Items of Systematic Review and Meta-Analysis Protocols.

Data Sources and Methods

Eight databases (PubMed, Scopus, Cochrane, Medline, CINAHL, JBI, EMBASE, Web of Science) were systematically searched using terms related to young people, HIV and PrEP use. A narrative synthesis approach was used to delineate key barriers and facilitators to PrEP access, uptake and use.

Results

Of 11,273 returned articles, 32 met the eligibility criteria for inclusion: 18 from the United States, 10 from African nations and two from Brazil. Barriers and facilitators to PrEP access, uptake and use experienced by young people were identified across intrapersonal, interpersonal, community and systems levels. These factors are described under four overarching themes that relate to knowledge, side effects and perceptions of risk; attitudes and perceptions of family and partners; community attitudes and stigma; and negative healthcare provider experiences and difficulties navigating complex costly healthcare systems.

Conclusion

Findings suggest individual-level factors need consideration alongside the impacts of healthcare systems and broader systemic sociocultural structures within young people's relationships when developing PrEP health promotion strategies and services. Without considering these wider external implications to access, uptake and use of PrEP, global targets towards the elimination of HIV transmission will likely remain out of reach.

Factors Associated with Planned Future Use of PrEP in the Next 3 Months and Likelihood to Use PrEP Among Black Cisgender HIV-negative Women in Texas

Identifying and then addressing barriers and leveraging facilitators is important to help increase pre-exposure prophylaxis (PrEP) use among Black women vulnerable to HIV acquisition. The present cross-sectional study examined what factors were associated with future plans to use PrEP, and general likelihood to use it among a convenience sample of 152 adult, Black cisgender women from three metropolitan areas in Texas. The final multivariable logistic regression model revealed that relationship status (aOR = 0.20, 95% CI: 0.05-0.73, p < 0.05), PrEP anticipated stigma (aOR = 0.29, 95% CI: 0.10-0.78, p < 0.05), perceived discrimination (aOR = 0.40, 95% CI: 0.21-0.78, p < 0.01) and interest in learning more about PrEP (aOR = 5.32, 95% CI: 2.60-10.9, p < 0.001) were associated with future plans to use PrEP. The final multivariable linear regression model with maximum likelihood estimation identified that perceived discrimination (β=-0.24, SE: -0.38 - -0.10, p < 0.01), perceived HIV risk (β = 0.33, SE: 0.18-0.49, p < 0.001), willingness to use PrEP with condoms (β = 1.26, SE: 0.94-1.60, p < 0.001), and comfort communicating about PrEP with a provider (β = 0.23, SE: 0.06-0.41, p < 0.01) were associated with general likelihood to use PrEP. Findings reveal key factors that warrant further attention and examination toward improving PrEP use within this population.

Pre-exposure prophylaxis uptake concerns in the Democratic Republic of the Congo: Key population and healthcare workers perspectives

Key populations (KP) in the Democratic Republic of the Congo (DRC), including female sex workers (SW), are disproportionally affected by HIV. Quantitative feedback surveys were conducted at seven health facilities in DRC with 70 KP clients enrolled in pre-exposure prophylaxis (PrEP) services to measure benefits and concerns. The surveys also assessed satisfaction with PrEP services and experiences of stigma at the health facilities. Thirty healthcare workers (HCW) were surveyed to measure attitudes, beliefs, and acceptability of providing services to KP. KP client survey participants were primarily female SW. KP clients reported that the primary concern about taking PrEP was fear of side effects (67%) although few KP reported having experienced side effect (14%). HCW concurred with clients that experienced and anticipated side effects were a primary PrEP uptake concern, along with costs of clinic visits.

"Protected Means Armed": Perspectives on Pre-Exposure Prophylaxis (PrEP) Among Women Who Engage in Sex Work and Use Drugs in Kazakhstan

Pre-exposure prophylaxis (PrEP) for HIV prevention has recently become available in Kazakhstan, but women engaged in sex work who use drugs (WESW-UD) could benefit from tailored approaches to support uptake and adherence. To better understand how best to support WESW-UD at each stage of the PrEP continuum (awareness, acceptability, uptake, and adherence), we analyzed data from 30 in-depth interviews and four focus groups with 48 WESW-UD from two cities in Kazakhstan. We conducted thematic analysis to characterize perceptions, barriers, and motivators within each step of the PrEP continuum. Participants reported low awareness, but high interest in PrEP. Motivating factors included optimizing health and increased confidence. Participants expressed many preferences and concerns regarding PrEP modality and delivery. Participants also described how organizational mistrust and social support can prevent or facilitate PrEP uptake or adherence. Kazakhstan's scale-up of PrEP should consider the needs and preferences of WESW-UD to ensure equitable access.

The experience of healthcare workers to HIV pre-exposure prophylaxis (PrEP) implementation in low- and middle-income countries: a systematic review and qualitative meta-synthesis

Background

The effectiveness of pre-exposure prophylaxis has been extensively documented. However, there are substantial gaps between the actual implementation of pre-exposure prophylaxis and the ideal goal, especially in low-and middle-income countries. Healthcare workers play critical roles in the pre-exposure prophylaxis implementation, and they have more multi-level experiences about the barriers of pre-exposure prophylaxis implementation and how to facilitate it. However, the evidence aiming to synthesize their experiences is limited.

Objective

This study aims to aggregate the healthcare workers' experiences of providing pre-exposure prophylaxis in low-and middle-income countries, and find the barriers, facilitators, and recommendations of pre-exposure prophylaxis implementation.

Methods

The ENTREQ (Enhancing transparency in reporting the synthesis of qualitative research) statement was used to guide the design and reporting of this qualitative meta-synthesis. A comprehensive search was conducted from inception of databases to 16th March 2023 in four databases: PubMed, CINAHL Plus with Full Text, Embase, Web of Science. The quality appraisal was conducted using the Joanna Briggs Institute Critical Appraisal Checklist. JBI's meta-aggregation approach was used to guide the data extraction and synthesis, and the JBI ConQual approach was used to evaluate the evidence level of the synthesized findings.

Results

Fourteen articles with good methodological quality were included in this review. A total of 122 findings were extracted and 117 findings with credibility ratings of "unequivocal" or "equivocal" were included in this meta-synthesis. The eligible findings were aggregated into 13 new categories and subsequently developed into 3 synthesized findings: the barriers, facilitators, and recommendations of pre-exposure prophylaxis implementation in low-and middle-income countries. The overall ConQual score of all three synthesized findings was rated as "low."

Conclusion

This review aggregated the experience of health care workers implementing pre-exposure prophylaxis in low-and middle-income countries and we could focus on the following key points to promote the uptake of pre-exposure prophylaxis: improve knowledge about pre-exposure prophylaxis, create a supportive environment, address medication-related barriers, increase the human resources and financial investments, and diversify the providing models.

Knowledge domain and emerging trends in HIV pre-exposure prophylaxis: A visualization analysis via CiteSpace

Background

As an effective strategy that reduces transmission among people at high risk of human immunodeficiency virus (HIV), pre-exposure prophylaxis (PrEP) has revolutionized HIV prevention. Our study aims to provide a reference for the development of relevant research and the formulation of prevention and control policies for HIV.

Methods

Through CiteSpace software, this study aims to present a comprehensive overview of the HIV PrEP knowledge structure, hotspots, and frontiers. We searched the Web of Science Core Collection for studies published between 2012 and 2022 related to HIV PrEP, and 3,243 papers remained after selection.

Results

The number of HIV PrEP publications has increased over the past few years. A close integration and exchange of HIV PrEP research findings has taken place between countries and authors. Major ongoing research trends include long-term injection PrEP, the impact of chlamydia on HIV PrEP, and individual awareness of and attitudes toward HIV PrEP. Thus, more attention should be paid to innovations and breakthroughs in drugs, the factors that affect HIV transmission and susceptibility, and the future promotion of public acceptance of HIV PrEP.

Conclusion

This study offers a systematic, objective, and comprehensive analysis of the related articles. It will assist scholars in understanding the dynamic evolution of HIV PrEP research and identifying future research areas to better advance the development of the field.

Variations in Pre-exposure Prophylaxis (PrEP) Awareness and Healthcare Provider Interactions in a Nationally Representative Sample of American Men Aged 15-49 Years: A Cross-Sectional Study

Awareness of and discussions with a healthcare provider (HCP) around pre-exposure prophylaxis (PrEP), an effective HIV prevention method, are associated with PrEP uptake, yet few studies utilize representative samples or report on these outcomes using distinct behavioral risk subgroups. This cross-sectional study utilized responses given by men on the 2017-2019 National Survey of Family Growth, a nationally representative survey of Americans aged 15-49 years. Multiple logistic regression models were used to determine how respondents' sociodemographic characteristics and HIV risk behaviors were related to PrEP awareness and HCP discussions. PrEP awareness was low (29.40%) as was the proportion who reported ever discussing PrEP with an HCP (4.48%). Odds of being PrEP aware and discussing PrEP with an HCP varied significantly within sexual behavior subgroups based on sociodemographic and behavioral characteristics highlighting the differential risks within distinct behavioral subgroupings of men. Sexual behavior subgroupings should be considered when promoting PrEP awareness and discussions as HIV risk behaviors vary considerably and sexual identity alone may not sufficiently capture one's HIV risk.

Preferences Across Pre-Exposure Prophylaxis Modalities Among Young Men Who Have Sex with Men in the United States: A Latent Class Analysis Study

Access to daily oral pre-exposure prophylaxis (PrEP) is suboptimal among young cisgender men who have sex with men (YMSM) in the United States. Next-generation modalities that do not involve daily oral regimens may mitigate some of the barriers to PrEP use. We identified latent classes of YMSM based on health care decision-making patterns and examined associations between latent classes and access to health care and PrEP modality preferences (i.e., daily and event-driven oral, rectal douches, broadly neutralizing antibodies, subcutaneous implants, and an injectable). Between October 2020 and June 2021, we administered an online survey to 737 YMSM. Latent class analysis (LCA) identified groups of YMSM based on communication with providers, stigma and mistrust in health care, and autonomy in sexual health decisions. Logistic regression examined associations between class membership and health care access, and exploded logit regression examined associations between class membership and ranked PrEP modality preferences. LCA identified three classes: shared decision-making (high communication with providers and high autonomy); provider-led decision-making (high communication and low autonomy); and patient-driven decision-making (low communication and high autonomy). Shared decision-making was associated with higher access to health care in comparison with the other classes. Across all classes, YMSM preferred daily oral PrEP over all next-generation PrEP modalities. Preferences for daily oral PrEP over next-generation PrEP modalities were particularly marked among the patient-driven decision-making class. Shared decision-making is associated with access to health care and HIV prevention and higher acceptability of next-generation PrEP modalities, and should be considered as part of future interventions to promote use of daily oral and next-generation PrEP.

Barriers and Facilitators to HIV Pre-Exposure Prophylaxis Uptake Among Men Who have Sex with Men Who Use Stimulants: A Qualitative Study

The HIV epidemic disproportionately impacts men who have sex with men (MSM), particularly those who use stimulants. We explored barriers and facilitators to pre-exposure prophylaxis (PrEP) uptake among this population. From June 2018 through February 2019, we conducted semi-structured interviews in Providence, Rhode Island, and New Haven, Connecticut, with 21 MSM who reported recent (past six months) stimulant use. We identified individual, interpersonal, and structural barriers to PrEP, including: (1) high awareness but mixed knowledge of PrEP, resulting in concerns about side effects and drug interactions; (2) interest that was partly determined by substance use and perceived HIV risk; (3) fragmented and constrained social networks not conducive to disseminating PrEP information; and (4) PrEP access, such as insurance coverage and cost. Our findings suggest potential approaches to increase PrEP uptake in this group, including promotion through mainstream and social media, clarifying misinformation, and facilitating increased access through structural interventions.

Race and Sexual Identity Differences in PrEP Continuum Outcomes Among Latino Men in a Large Chicago Area Healthcare Network

U.S. HIV incidence is threefold higher among Latino individuals than non-Latino Whites. Pre-exposure prophylaxis (PrEP) uptake remains low among Latino men. Most HIV studies view Latino communities as a monolithic group, ignoring racial and sexual diversity. This analysis examines PrEP-related outcomes including eligibility, first prescription, and second prescription across race and sexual identity in a sample of Latino cisgender men (n = 8271) who sought services from a healthcare network in Chicago in 2012-2019. Logistic regression was used to calculate adjusted odds ratios. Latino-only participants had lower odds of PrEP eligibility and first prescription compared to White-Latino participants. No other significant differences by race were detected. While bisexual participants had equivalent odds of PrEP eligibility, they had lower odds of first PrEP prescription compared to gay participants. Heterosexual participants also had lower odds of PrEP eligibility and initiation. Future research should address unique factors shaping PrEP-related outcomes among diverse Latino populations.

Relationships among Substance Use, Sociodemographics, Pre-Exposure Prophylaxis (PrEP) Awareness and Related Attitudes among Young Adult Men Who Have Sex with Men

Men who have sex with men (MSM) account for two-thirds of new HIV diagnoses. Pre-exposure prophylaxis (PrEP), a highly efficacious HIV preventive medication, is underutilized. Identifying correlates of PrEP awareness and attitudes may help increase PrEP use. Thus, we evaluated (1) PrEP awareness; (2) differences in awareness related to substance use and sociodemographics; (3) initial PrEP information sources; and (4) possible associations between information sources and PrEP-related attitudes.

Young adult (ages 18-30) HIV-negative MSM from Southern U.S. undertook a web survey including questions about substance use, sexual behaviors, perceived HIV risk, and PrEP. Participants were recruited using in-person and online approaches between January 2018-January 2020.

Of 506 participants, 89% were aware of PrEP. Participants with high alcohol consumption and greater perceived HIV risk had higher odds of PrEP unawareness with a trend for minority race/ethnicity. PrEP-aware participants reported high overall perceived safety, confidence in PrEP's efficacy, and low perceived difficulties with adherence though those with higher perceived HIV risk and individuals who used tobacco had less favorable attitudes. Most participants first heard about PrEP from the internet. There were no statistically significant differences in PrEP-related attitudes across initial information sources.

Associations between substance use and racial/ethnic minority status and lack of PrEP awareness suggest priority subgroups for educational campaigns. Future campaigns may tailor outreach materials to the respective audience (e.g., Spanish materials for Hispanic people) and disseminate where individuals who use substances may be more likely to see them (e.g., liquor and convenience stores).

Crowdsourced PrEP Promotion Messages for an HIV High-Burden Area: A Framework-Based Content Analysis

Pre-exposure prophylaxis (PrEP) is an important and highly effective HIV prevention strategy, but its uptake remains low, particularly among marginalized populations at high risk of HIV. Innovative and community-driven promotion strategies, such as open contests, are needed to address disparities. This directed content analysis uses a PrEP-specific adaptation of the Information-Motivation-Behavioral Skills (IMB) model to identify themes related to PrEP use reflected in community-generated submissions (n = 73) from an open contest conducted to elicit crowdsourced health promotion messages on PrEP in Baltimore, Maryland. In addition to identifying eight of the themes from the adapted IMB model, this analysis also identified two novel salient themes in the motivation category: self-worth/self-love and self-care practice. Findings from this analysis can inform PrEP promotion efforts by pointing to salient themes identified from a community-driven approach that are less well represented in existing research.

Awareness of HIV Preexposure Prophylaxis Among People at Risk for HIV: Results From the 2017-2019 National Survey of Family Growth

BACKGROUND

Although daily preexposure prophylaxis (PrEP) is now widely accepted as a safe and effective method for reducing the risk of HIV in high-risk groups, uptake has been slow. The goal of this analysis was to identify factors associated with PrEP awareness among individuals at risk for HIV.

METHODS

This investigation analyzed data from the Centers for Disease Control and Prevention nationally representative survey, National Survey of Family Growth, for the years 2017 to 2019. Logistic regression was used to explore the relationship between PrEP awareness and demographics, HIV risk factors, and provider HIV risk screening.

RESULTS

Only 37% of survey respondents with an increased risk of HIV were aware of PrEP. Several segments of the at-risk population had lower odds of being aware of PrEP, including heterosexual women, heterosexual men, individuals younger than 20 years, and individuals with lower levels of education. Those who participate in sex in exchange for money or drugs had significantly lower odds of being aware of PrEP. In comparison, PrEP awareness was significantly higher among nonheterosexual men and both men and women whose partners were HIV positive. Lastly, those who had been screened by a provider for HIV risk had significantly higher odds of being aware of PrEP.

CONCLUSIONS

This research supports the need for policies and programs to increase awareness of PrEP, especially among certain segments of the population at increased risk for HIV.

Social Media & PrEP: A Systematic Review of Social Media Campaigns to Increase PrEP Awareness & Uptake Among Young Black and Latinx MSM and Women

Pre-exposure prophylaxis (PrEP) has been shown to be highly effective at reducing the risk of HIV. Despite efforts to employ various social marketing strategies to promote PrEP among young people at greater risk for HIV, PrEP awareness and uptake remain low. We conducted a comprehensive review of current literature that presents or evaluates the use of social media and/or specific communication campaigns to increase PrEP awareness among young Black and Latinx men who have sex with men (MSM) and women. Eight articles met the inclusion criteria for the final analysis. The most used platforms included Facebook, Instagram, and custom mobile applications. Social media is a dynamic and promising tool that may be used to increase PrEP awareness, uptake, and adherence among young Black and Latinx MSM and women.

Community Legal Systems: Targeting PrEP and HIV Education to Decrease Risk of HIV Transmission

The southern U.S. has both high HIV and incarceration rates in comparison to its population. As in the rest of the country, HIV prevention is based on education, behavior change, and biomedical efforts, such as pre-exposure prophylaxis (PrEP). This study examined the implementation of an educational intervention and supportive services to obtain PrEP in a population of individuals (N = 218) involved in an Adult Drug Court (ADC) or on probation or parole (P-P). Nearly all ADC and P-P participants self-reported risk behaviors linked to HIV acquisition. Results supported the acceptance and usefulness of the intervention as rated by participants. Participants showed increased knowledge of HIV risks and testing post-education. In multivariate analysis, predictors of interest in using PrEP included low stigma beliefs, specifically their level of prejudice views, high depressive symptoms, and white race. The intervention shows promise. Given the high risk documented for ADC and P-P individuals, HIV prevention is a critical component for increased protective behaviors.

Pre-exposure Prophylaxis (PrEP) Information on Instagram: Content Analysis

Background

There is still an HIV epidemic in the United States, which is a substantial issue for populations bearing a disproportionate burden of HIV infections. Daily oral pre-exposure prophylaxis (PrEP) has proven to be safe and effective in reducing HIV acquisition risk. However, studies document that PrEP awareness/usage is low. There is also limited understanding of social media platforms, such as Instagram, as PrEP information sources.

Objective

Given the paucity of research on PrEP-related Instagram posts and popularity of this social media platform, the purpose of this research is to describe the source characteristics, image types, and textual contents of PrEP-related posts on Instagram.

Methods

Using Crowdtangle Search, a public insights tool owned/operated by Facebook, we retrieved publicly accessible and English-language-only Instagram posts for the 12-month period preceding April 22, 2020, using the following terms: Truvada or “pre-exposure prophylaxis” or #truvada or #truvadaprep or #truvadawhore or #truvadaforprep. We employed a qualitative coding methodology to manually extract information from posts. Using a pretested codebook, we performed content analysis on 250 posts, examining message and source characteristics (ie, organization type [eg, government, news] and individual type [eg, physician]), including information about PrEP (eg, how it works, cost), and indicated users. Frequencies and percentages were calculated for all categorical variables. A Chi-square test was conducted to determine differences between source types on a variety of message characteristics.

Results

Three-quarters of the posts (193/250, 77.2%) were posted by organizations. Of the 250 posts reviewed, approximately two-thirds (174/250, 69.6%) included a photograph, more than half (142/250, 56.8%) included an infographic, and approximately one-tenth (30/250, 12%) included a video. More than half defined PrEP (137/250, 54.8%), but fewer posts promoted PrEP use, explained how PrEP works, and included information on the effectiveness of PrEP or who can use it. The most commonly hashtagged populations among posts were men who have sex with men (MSM), but not necessarily bisexual men. Few posts contained race-/ethnicity-related hashtags (11/250, 4.4%). Fewer posts contained transgender-associated tags (eg, #transgirl; 5/250, 2%). No posts contained tags related to heterosexuals or injection drug users. We found statistical differences between source types (ie, individual versus organization). Specifically, posts from organizations more frequently contained information about who can use PrEP, whereas posts from individuals more frequently contained information describing adverse effects.

Conclusions

This study is among the first to review Instagram for PrEP-related content, and it answers the National AIDS Strategy’s call for a clearer articulation of the science surrounding HIV risk/prevention through better understanding of the current public information environment. This study offers a snapshot of how PrEP is being discussed (and by whom) on one of the most popular social media platforms and provides a foundation for developing and implementing PrEP promotion interventions on Instagram.

The Pre-exposure Prophylaxis (PrEP) Care Cascade in People Who Inject Drugs: A Systematic Review

Injection drug use is a key risk factor for the transmission of HIV. Prevention strategies, such as the use of pre-exposure prophylaxis (PrEP), are effective at reducing the risk of HIV transmission in people who inject drugs (PWID). Following PRISMA guidelines, a literature search was conducted to identify the current state of the PrEP care cascade in PWID. Twenty-three articles were evaluated in this systematic review. A decline in engagement throughout the stages of the PrEP care cascade was found. High awareness and willingness to use PrEP was found, yet PrEP uptake was relatively low (0-3%). There is a lack of research on interventions to increase engagement of PrEP across all levels of the care cascade in PWID. Implications from the interventions that have been published provide insight into practice and public policy on efficacious strategies to reduce HIV incidence in PWID. Our findings suggest that more efforts are needed to identify and screen PWID for PrEP eligibility and to link and maintain them with appropriate PrEP care.

Reducing HIV Risk Behaviors Among Black Women Living With and Without HIV/AIDS in the U.S.: A Systematic Review

This systematic review provides an examination of the status of HIV/AIDS prevention interventions for Black, heterosexual women in the U.S. from 2012 to 2019. Using PRISMA guidelines, 28 interventions were identified. Over half of the interventions were: conducted in the southern region of the U.S.; evaluated using a randomized controlled trial; focused on adults; used a group-based intervention delivery; were behaviorally focused and theoretically driven. None included biomedical strategies of PrEP, nPEP, and TasP. Few interventions included adolescent or aging Black women; none included their sex/romantic partners. Future studies dedicated to addressing the specific needs of subpopulations of Black, heterosexual women may provide opportunities to expand and/or tailor current and future HIV/AIDS prevention interventions, including offering participants with options to choose which, and the level of involvement, of their sex/romantic partner(s) in their sexual health decision-making. While strides to improve HIV prevention efforts with Black, heterosexual women have occurred, more is needed.

Awareness and uptake of pre-exposure prophylaxis for HIV among low-income, HIV-negative heterosexuals in San Francisco

We examined pre-exposure prophylaxis (PrEP) awareness and uptake among low-income heterosexual men and women in San Francisco in 2019. Of 294 HIV-negative survey participants, 42.5% were aware of PrEP. Few women (12.5%) and men (8.9%) had discussed PrEP with a healthcare provider; 3.8% of women and 0% of men had used PrEP in the last year. White participants (adjusted odds ratio (aOR) 5.39, 95% CI 1.02, 28.56), women (aOR 2.19, 95% CI 1.30, 3.70), and age 60 years or above (aOR 4.00, 95% CI 1.12, 14.34) had greater odds of being aware of PrEP. Testing for HIV or sexually transmitted infection in the past year was marginally associated with a greater PrEP awareness. Our findings reveal gaps in PrEP implementation associated with social disparities among low-income heterosexuals. Testing services and targeted promotional and educational materials are needed lest high-risk, low-income populations are left behind in San Francisco's aggressive "Getting to Zero" efforts.

Health Profession Students' Awareness, Knowledge, and Confidence Regarding Preexposure Prophylaxis: Results of a National, Multidisciplinary Survey

BACKGROUND

Preexposure prophylaxis (PrEP) is a highly effective, pharmacologic method of HIV prevention. Despite its safety and efficacy, PrEP prescription remains low in those patients who are at highest risk for HIV infection. One possible reason for this may be the lack of inclusion of PrEP and HIV prevention discussions within the curricula of health professions education.

METHODS

An online survey was administered to a cross-sectional sample of future prescribers (osteopathic/allopathic medical and physician assistant students), future nurses, and future pharmacists (n = 2085) in the United States between January and July 2019 to assess and compare awareness of PrEP, PrEP education, PrEP knowledge, and confidence in 2 areas related to PrEP.

RESULTS

We show that, overall, awareness of PrEP is high among future health care providers (81.6%), with the future pharmacists reporting the greatest awareness (92.2%; P < 0.001) and more commonly reporting PrEP education (71.0%). Students had mixed knowledge of PrEP, with future pharmacists reporting the highest knowledge of PrEP. Approximately 30% of students in all disciplines reported having low confidence counseling a patient about PrEP and low confidence educating a colleague about PrEP. Knowledge of PrEP was a significant predictor of confidence counseling a patient about PrEP (P < 0.001) and educating a colleague about PrEP (P < 0.001).

CONCLUSIONS

This study identifies opportunities to improve and incorporate evidence-based strategies for educating future health care providers about PrEP for HIV prevention within health professions curricula.

Student Education About Pre-exposure Prophylaxis (PrEP) Varies Between Regions of the United States

BACKGROUND

Daily, oral pre-exposure prophylaxis (PrEP) is an effective and safe prevention strategy for people at risk for HIV. However, prescription of PrEP has been limited for patients at the highest risk. Disparities in PrEP prescription are pronounced among racial and gender minority patients. A significant body of literature indicates that practicing healthcare providers have little awareness and knowledge of PrEP. Very little work has investigated the education about PrEP among health professionals in training.

OBJECTIVE

The objective of this study was to compare health professions students' awareness of PrEP and education about PrEP between regions of the US, and to determine if correlations between regional HIV incidence and PrEP use were present.

DESIGN

Survey study.

PARTICIPANTS

A cross-sectional sample of health professions students (N = 1859) representing future prescribers (MD, DO, PA), pharmacists, and nurses in the US.

KEY RESULTS

Overall, 83.4% of students were aware of PrEP, but only 62.2% of fourth-year students indicated they had been taught about PrEP at any time during their training. Education about PrEP was most comprehensive in the Northeastern US, the area with the highest PrEP to need ratio (4.7). In all regions, transgender patients and heterosexual men and women were least likely to be presented in education as PrEP candidates, and men who have sex with men were the most frequently presented.

CONCLUSIONS

There are marked differences in education regarding PrEP both between academic programs and regions of the USA.

HIV Pre-Exposure Prophylaxis Prevention Awareness, Willingness, and Perceived Barriers among People Who Inject Drugs in Los Angeles and San Francisco, CA, 2016-2018

BACKGROUND

Pre-exposure prophylaxis (PrEP) for HIV prevention is indicated for people who inject drugs (PWID), yet most studies do not focus on PWID. This study examines factors associated with PrEP awareness and willingness, and identifies perceived barriers to PrEP among PWID. Methods: PWID were interviewed in Los Angeles and San Francisco, CA from 2016 to 2018. We analyzed data from self-reported HIV-negative participants who had injected drugs within the past 6 months (n = 469). Questions on PrEP included awareness, willingness, barriers, and uptake. Multiple logistic regression models of factors associated with awareness of, and willingness to, take PrEP were developed. Descriptive statistics on perceived PrEP barriers are reported. Results: Among HIV-negative PWID, 40% were aware of PrEP, 59% reported willingness to take PrEP, and 2% were currently taking PrEP. In multivariable analysis, PrEP awareness was associated with study site and sexual minority status, higher educational attainment, and HIV testing in the last 6 months. Willingness to take PrEP was associated with self-reported risk (paying sex partner in the last 6 months, sharing drug paraphernalia, and being injected by another PWID) and perceived HIV risk. The most common perceived barriers to PrEP were copays, concerns about increased HIV or sexually transmitted risk with PrEP, and concerns about reduction of medication efficacy without daily use. Conclusion: PrEP awareness among PWID remains inadequate. Willingness to take PrEP was moderate and was most desired by PWID who engaged in high-risk behaviors. Interventions to increase PrEP awareness and willingness, and to facilitate PrEP uptake among PWID are needed.

A Narrative Review of Continuing Professional Development Needs for Pharmacists with Respect to Pre-exposure Prophylaxis (PrEP) for Human Immunodeficiency Virus (HIV)

Pre-exposure prophylaxis (PrEP) for the human immunodeficiency virus (HIV) is rapidly increasing in use worldwide, with many countries now publicly funding use for high risk populations. Pharmacists, as front-line care providers, must have the necessary knowledge, skills and attitudes to effectively provide care to PrEP patients. The aim of this review was to identify priority areas and key gaps for continuing professional development (CPD) needs relating to PrEP for practicing pharmacists. An electronic search of PubMed, EMBASE, International Pharmaceutical Abstracts and CPD-related journals was supplemented with a manual search of references to identify articles describing pharmacists’ knowledge, perceptions and experience with PrEP. A total of eight articles were identified across four countries. Pharmacists were consistently found to lack knowledge and awareness of PrEP, express low confidence/comfort with patient care practices, report a lack of experience and/or intentions to provide patient care, but overall had positive perceptions of PrEP therapy. Older pharmacists with more experience commonly reported greater knowledge gaps than recently trained pharmacists. CPD should therefore aim to increase pharmacists’ baseline knowledge and awareness of PrEP and treatment guidelines, as well as be directed towards older pharmacists with more experience.

Barriers to the Wider Use of Pre-exposure Prophylaxis in the United States: A Narrative Review

Antiretroviral pre-exposure prophylaxis (PrEP) to prevent HIV transmission was first approved by the US Food and Drug Administration in 2012. Despite correlations of decreases in new HIV infections being greatest where PrEP has been deployed, the uptake of PrEP is lagging, particularly among populations with disproportionate HIV burden. This narrative review seeks to identify individual and systemic barriers to PrEP usage in the USA. A comprehensive search of recent literature uncovered a complex array of structural, social, clinical, and behavioral barriers, including knowledge/awareness of PrEP, perception of HIV risk, stigma from healthcare providers or family/partners/friends, distrust of healthcare providers/systems, access to PrEP, costs of PrEP, and concerns around PrEP side effects/medication interactions. Importantly, these barriers may have different effects on specific populations at risk. The full potential of PrEP for HIV prevention will not be realized until these issues are addressed. Strategies to achieve this goal should include educational interventions, innovative approaches to delivery of HIV care, financial support, and destigmatization of PrEP and PrEP users. Until then, PrEP uptake will continue to be suboptimal, particularly among those who need it most.
