HIV Preexposure Prophylaxis, by Race and Ethnicity - United States, 2014-2016

HIV Infections and Prevention in Women

This paper examines the challenges and advancements related to human immunodeficiency virus (HIV) in women, focusing on incidence, disparities, and reproductive health. HIV disproportionately affects Black women, with socioeconomic and health care access factors worsening outcomes. Pre-exposure prophylaxis (PrEP) is promising but underutilized due to awareness and accessibility issues. Contraception access and abortion care remain limited for women living with HIV, while menopause poses additional health risks. Future directions in research and policy call for expanded prevention, improved health care services, and greater support for reproductive and menopausal care, aiming to enhance health care equity and quality of life for women affected by HIV.

Brief Report: Behavioral Readiness for Daily Oral PrEP in a Diverse Sample of Gay, Bisexual, and Other Men Who Have Sex With Men Who Have Not Been Offered PrEP by a Provider

BACKGROUND

Daily oral pre-exposure prophylaxis (PrEP) use among gay, bisexual, and other men who have sex with men (GBMSM) remains suboptimal. Assessing behavioral readiness for PrEP use among GBMSM who can benefit and offering PrEP may increase uptake among GBMSM. We measured 4-item readiness for taking PrEP among GBMSM who have not been offered PrEP by a provider.

METHODS

GBMSM in Atlanta, Chicago, and Raleigh-Durham reporting recent condomless anal sex were assessed for "readiness" to discuss PrEP with a provider, test for HIV, take a daily pill, attend provider appointments, and a 4-component composite score for PrEP readiness. χ 2 tests and multivariable logistic regression were applied to examine factors associated with readiness to use PrEP.

RESULTS

Study sample (n = 187) was 51% Black/African American, 15% Hispanic/Latino, 30% identified as bisexual or straight or other, and 29% had no health insurance. In total, 55% said they were ready to discuss PrEP with a provider, 88% were ready to get an HIV test, 45% were ready to take a daily pill, 48% were ready to attend appointments, and 37% reported overall PrEP readiness. Having no health insurance was associated with readiness for a daily pill [adjusted odds ratio (AOR) = 2.78, confidence interval (CI) = 1.34-5.78] and 4-item PrEP readiness (AOR = 2.34, CI = 1.13-4.85). Self-identification as gay (vs bisexual/straight) was associated with readiness to discuss PrEP (AOR = 2.14, CI = 1.05-4.36).

CONCLUSIONS

Only 37% of GBMSM with recent condomless anal sex were ready for PrEP based on the 4-item readiness. Readiness may differ based on sexual identity, insurance status, and other characteristics. Efforts are needed to increase readiness across behavioral components of PrEP use.

Experiences, Attitudes and Preferences of Postpartum Cisgender Women for HIV Prevention and Pre-Exposure Prophylaxis Education during Routine Postpartum Care

The postpartum period presents an opportunity to deliver comprehensive sexual health education. Understanding preferences of postpartum cisgender women (CGW) towards integration of HIV prevention education into postpartum care is necessary to support acceptability, appropriateness, and feasibility. Postpartum CGW were recruited during their postpartum hospital stay in Bronx, NY. Participants completed a survey including two best-worst scaling exercises that elicited preferences for receiving HIV prevention information and PrEP messaging. Utility scores were estimated using a hierarchical Bayes multinomial logit model and mathematically transformed into a probability scale presented as preference scores (PS), with higher numbers representing greater preference. Among 259 participants, 53% had never heard of PrEP before. Receiving information from a doctor was most preferred (13.4, 95%CI 12.7-14.0) followed by receiving information about HIV prevention combined with taking care of their health after having a baby (11.6, 95% CI 10.9-12.3). Latent class analysis revealed three classes: participants with greater preference for high touch services (e.g., in-person visits, doctor providing information), integrated information (e.g., HIV prevention information given in combination with sexual or maternal health information) and high technology services (e.g., a mobile phone application, telehealth visit). Participants preferred PrEP messaging related to themes of effectiveness, motherhood, safety and autonomy. Latent class analysis of PrEP messaging revealed two classes: one with participants preferring messages related to motherhood and safety and another preferring messages related to control and autonomy. The heterogeneity in preferences for receiving information at the patient level suggests a need for patient-centered, differentiated service delivery to support maximum receptivity.

Emergency Department Patients' Perspectives on Being Offered Human Immunodeficiency Virus Pre-Exposure Prophylaxis Services in an Urban Emergency Department

HIV pre-exposure prophylaxis (PrEP) is underutilized in the United States. Emergency departments (EDs) can be strategic locations for initiating PrEP; however, knowledge concerning patients' receptivity to ED PrEP programs is limited. This study explores ED patients' perspectives on PrEP service delivery and their preferences for implementation. Semi-structured qualitative interviews were conducted with 15 potentially PrEP-eligible ED patients to examine their receptiveness to PrEP services, preferences for delivery methods, and logistical considerations. Most participants were open to learning about PrEP in the ED, provided it did not delay care, occur during distress, or compromise privacy. Universal PrEP education was viewed as reducing stigma and increasing awareness, while targeted screening was considered efficient. Participants strongly preferred receiving information in person rather than via videos or pamphlets. Concerns included ensuring ED staff expertise and maintaining privacy during PrEP-related discussions. Opinions on initiating same-day PrEP versus prescriptions or referrals varied, with participants valuing flexibility and linkage to care. This first qualitative study of ED patients' perspectives on PrEP services highlights general receptiveness, with key concerns about privacy, expertise, and wait times. Patient-centered approaches, such as integrating services into ED workflows, offering flexible initiation options, and providing privacy, can address barriers and enhance the feasibility of ED-based PrEP programs.

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.

Uptake of HIV Preexposure Prophylaxis Among Medicare Beneficiaries-United States, 2014-2021

BACKGROUND

Previous studies have estimated preexposure prophylaxis (PrEP) use among persons with commercial health insurance and Medicaid. However, data are lacking regarding PrEP use among those with Medicare.

METHODS

Using a previously developed algorithm, we estimated the number of Medicare beneficiaries (MBs) with fee-for-service claims who were prescribed PrEP from 2014 to 2021. The analysis was stratified by age, sex, and race/ethnicity. We also examined trends in PrEP prevalence by U.S. state and demographic characteristics during 2014-2021.

RESULTS

The number of Medicare PrEP users increased 11-fold, from 388 in 2014 to 4685 in 2021. MBs prescribed PrEP were predominantly younger men, White persons, residing in the south or west regions, living with a disability, and dually eligible for both Medicare and Medicaid. The prevalence of PrEP prescriptions among MBs increased 12-fold, from 9.7 per million in 2014 to 120.0 per million in 2021. Black/African American persons had the highest prevalence of PrEP use, followed by Hispanic/Latino and White persons in 2021. The District of Columbia had the highest prevalence of PrEP use compared with other U.S. states in 2021. Significant increasing trends in PrEP use were observed across sex, age groups, and race/ethnicity.

CONCLUSIONS

Disparities in PrEP uptake existed across MB demographic subgroups from 2014 to 2021. Public health interventions are needed to increase PrEP access and utilization, particularly among women, younger MBs, Black persons, and Hispanic persons, including those with Medicare. Strategies and policies to expand PrEP use are essential for optimal HIV prevention in the United States.

PrEP knowledge and perceptions among women living in North Carolina public housing communities

Women in low-income communities are disproportionately affected by HIV yet have been largely left out of efforts to raise awareness about pre-exposure prophylaxis (PrEP). To inform future awareness campaigns, we assessed women's current knowledge of and attitudes toward PrEP. We surveyed 184 women living in public housing communities in North Carolina regarding PrEP knowledge, attitudes, and perceived norms, as well as reported HIV-associated factors and perceived HIV acquisition chances. 38 women participated in eight focus group discussions (FGDs) addressing personal and community PrEP perceptions. Survey participants were 46 years old on average, and 86% identified as Black/African American. Only 35% had heard of PrEP, yet, after being told what it was, 61% said they probably or definitely would take PrEP in the next 6 months. Most women believed that if they decided to take PrEP, their partner (72%) or their family (66%) would approve. When asked about the importance of factors influencing their interest in PrEP, women most frequently rated possible side effects as important or very important (76%), followed by cost considerations (67% for cost of PrEP, 74% for cost of clinic visits and labs). In the FGDs, women had limited PrEP knowledge, but several had heard of PrEP from television commercials, which gave them the impression that PrEP was only for men. Women were concerned about potential side effects, interactions with other medications, safety during pregnancy, and the burden of daily dosing. Most FGD participants expressed generally positive attitudes toward PrEP, but some thought other women would be uninterested due to low perceived chances of HIV acquisition. Overall, these results suggest that while few women had previously heard of PrEP, most were interested in PrEP after receiving information about it and perceived positive community attitudes toward PrEP. Our findings indicate the importance of community-based PrEP communication that speaks to cisgender women, provides information on side effects, and offers destigmatized messaging regarding reasons for HIV prevention for women to consider.

A Multicomponent Strategy to Improve HIV Pre-Exposure Prophylaxis in a Southern US Jail: Protocol for a Type 3 Hybrid Implementation-Effectiveness Trial

BACKGROUND

Pre-exposure prophylaxis (PrEP) is an effective approach for preventing HIV infection, but it is underutilized by populations who may benefit the most, including people living in the Southern United States and those involved in the criminal legal (CL) system. Improving the access and use of PrEP for these groups could decrease HIV-related health disparities. Beyond individual outcomes, HIV prevention for CL-involved people can have a significant public health impact on HIV incidence due to a high turnover between jails and the community.

OBJECTIVE

We will develop, implement, and evaluate a multicomponent PrEP implementation strategy for the Dallas County Jail (DCJ) to increase the initiation of this HIV-preventive intervention for CL-involved individuals.

METHODS

This is a type 3 hybrid implementation-effectiveness study that takes a combined approach by assessing the implementation of a strategy to identify candidates for PrEP at the DCJ and linking them to PrEP providers upon community re-entry while also gathering information about clinical outcomes. The approach is guided by the EPIS (exploration, preparation, implementation, sustainment) framework. Initial formative work (exploration) involves qualitative interviews of diverse key stakeholders to identify factors that may influence linkage to PrEP after jail release. These findings will undergo rapid qualitative analysis (preparation) to inform the adaptation of a multicomponent jail PrEP implementation strategy protocol. This approach, which will include an electronic health record (EHR) prediction model and integration of a PrEP patient navigator into the jail health team, will allow medical providers and the navigator at the DCJ to engage individuals most likely to benefit in shared decision-making about PrEP and navigate them to community PrEP care (implementation) in a process that begins before release from jail and ends with successful care linkage. Regular quantitative and qualitative evaluations of this approach will allow for ongoing stakeholder input, refinement of the implementation strategy, and maintenance of the program (sustainment).

RESULTS

Findings from 26 qualitative interviews (9 formerly incarcerated individuals, 9 county jail staff, and 8 employees of community organizations) have been obtained, analyzed, and mapped to an implementation strategy formalized in a jail PrEP protocol. An HIV risk prediction model based on EHR data to identify individuals most likely to benefit from PrEP has been developed and internally validated and is ready to be deployed. We anticipate the availability of preliminary study findings in 2026.

CONCLUSIONS

This study will provide key insights into the feasibility and effectiveness of a PrEP implementation strategy among people at increased risk of HIV acquisition in an urban jail in Southern United States. This practical and scalable strategy can be used as a model for other urban jails to address HIV-related inequities.

Linking Black women to PrEP care using warm handoff referrals from emergency departments to local PrEP clinics

New Human Immunodeficiency Virus (HIV) cases continue to disproportionately burden cisgender Black/African American women in the United States due to a confluence of structural and systemic factors. Pre-exposure prophylaxis (PrEP) is a safe and effective HIV prevention option, yet there is a striking gap between PrEP eligibility and uptake among cisgender Black women. The current study evaluates a novel warm handoff process in a hospital emergency department setting linking eligible women to local PrEP clinics within 72 hours of hospital discharge in a large southwestern metropolitan city. Participants received follow-up telephone consultations at 1-month (T1), 3-months (T2), and 6-months (T3) post-enrollment. Of 40 participants, one was successfully linked to their initial PrEP clinic visit. One additional participant reported attending their PrEP visit, but staff were unable to confirm linkage. Twenty-eight percent of participants attended follow-up telephone visits at T1, T2, and T3, while 35% of participants attended a combination of some, and 37% of participants did not engage in any follow-up visits. Findings suggest that culturally tailored linkage interventions are suitable mechanisms for engaging cisgender Black women in PrEP care. Implications for future research include exploring the sustainability and scalability of such interventions are discussed.

Causal Effects of Alcohol Consumption on Condom Negotiation Skills of Women with Varying Sexual Assault Histories

Sexual assault victimization experience and alcohol consumption are well-documented HIV risk factors for women who have sex with men (WSM). Nonetheless, behavioral mechanisms of the synergistic effects of these factors on women's increased HIV risk are not well delineated. This study is the first to examine the interactive effects of sexual assault history and acute intoxication on women's condom negotiation behavior during a face-to-face role-play with a male actor. Participants were female, single, social drinkers, ages 21 to 35, recruited from the community. Women were categorized as having experienced past sexual assault victimization or not based on their questionnaire responses, then were randomly assigned to consume either no alcohol or alcohol (0.08 target BAC) and engaged in a role-play with a male actor that included condom use negotiation. Participants' verbal, paraverbal, and nonverbal behavior was video recorded and coded by independent raters. As hypothesized, sexual assault history interacted with alcohol condition to significantly influence participants' assertive condom negotiation behavior. These results further our scientific understanding of how intoxication may exacerbate the relationship between sexual assault history and HIV risk, and can inform prevention programs tailored to the unique needs of WSM who have a history of sexual assault victimization and are social drinkers.

Emergency Department Patients' Perspectives on Being Offered HIV Pre-Exposure Prophylaxis (PrEP) Services in an Urban ED

HIV pre-exposure prophylaxis (PrEP) is underutilized in the United States. Emergency Departments (EDs) can be strategic locations for initiating PrEP; however, knowledge concerning patients' receptivity to ED PrEP programs is limited. This study explores ED patients' perspectives on PrEP service delivery and their preferences for implementation. Semi-structured qualitative interviews were conducted with 15 potentially PrEP-eligible ED patients to examine their receptiveness to PrEP services, preferences for delivery methods, and logistical considerations. Most participants were open to learning about PrEP in the ED, provided it did not delay care, occur during distress, or compromise privacy. Universal PrEP education was viewed as reducing stigma and increasing awareness, while targeted screening was seen as efficient. Participants strongly preferred receiving information in person rather than via videos or pamphlets. Concerns included ensuring ED staff expertise and maintaining privacy during PrEP-related discussions. Regarding same-day PrEP versus prescriptions or referrals, opinions varied, with participants valuing flexibility and linkage to care. This first qualitative study of ED patients' perspectives on PrEP services highlights general receptiveness, with key concerns about privacy, expertise, and wait times. Patient-centered approaches, including integrating PrEP services into ED workflows, offering flexible initiation options, and providing privacy, can support the feasibility of ED-based PrEP programs.

Demographical and Regional Trends of HIV-Related Mortality Among Young Adults in the United States From 1999 to 2020

BACKGROUND

HIV remains a leading cause of death in the U.S. Previous research has examined mortality patterns among older adults with HIV, revealing regional and demographic disparities. This study aims to assess demographic and regional trends in HIV-related mortality among young adults from 1999 to 2020.

METHODS

Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research database was used to identify young adults aged 15-44 where HIV was mentioned as either underlying or contributory cause of mortality between 1999 and 2020, using the B20-B24 codes from the International Statistical Classification of Diseases and Related Health Problems-10th Revision (ICD-10). Age-adjusted mortality rates (AAMRs) per 100,000 population and annual percentage change (APC) were determined.

RESULTS

The AAMRs for HIV in young adults consistently declined from 1999 to 2018, followed by a period of stability from 2018 to 2020 (annual percentage change: 0.5%; 95% confidence interval [95% CI], -7.4 to 9.0), with 64% deaths occurred in medical facilities. Overall, males had a twice AAMR than females (female: 2.22, 95% CI 2.19-2.24; male: 5.19, 95% CI 5.15-5.23). Non-Hispanic (NH) Blacks had sevenfold higher mortality rates than Whites (AAMR 14.88 vs. 2.036). The Southern region experienced threefold higher mortality compared to the Midwest. Metropolitan adults had a twofold higher AAMR than nonmetropolitan adults. States in the top 90th percentile for HIV-related mortality, including Mississippi, Maryland, Florida, Louisiana, and the District of Columbia, exhibited six times higher mortality compared to states in the bottom 10th percentile, such as North Dakota, Idaho, Wyoming, Montana, and Utah.

CONCLUSIONS

To address these disparities and ensure continued progress, urgent measures are required.

Characterizing Event-Driven PrEP Use and Investigating its Association with Experiences of PrEP-Related Barriers Among a US National Sample of PrEP Users

After a decade of implementation in the US, PrEP uptake remains underutilized by communities that would greatly benefit from it. Event-Driven (ED) PrEP is a potential avenue to increase uptake, however very little is known about its use in the US. We analyzed data derived from Together 5000, an internet-based U.S. national cohort of Sexual and Gender Minority (SGM) individuals aged 16-49 years and at risk for HIV. First, we looked at predictors of ED PrEP use using a framework based on current US-based PrEP implementation-related variables. Then, we explored whether experiencing certain types of barriers were associated with choice of ED PrEP over daily PrEP using logistic regression analysis. Our findings showed that variables related to education and sexual behaviors were associated with ED PrEP choice, while experiencing barriers to daily PrEP had no effect. We found a gradient effect with education, where individuals who reported having some college had 3 times the odds of taking ED PrEP, those reporting a bachelor's degree had 3.25 times the odds, and those with graduate school education had 7.56 times the odds of choosing ED PrEP compared to those with a high school diploma or less. Individuals who reported having 2 or more hours of lead time for sex had 3.35 times the odds of using ED PrEP (aOR = 3.35, 95% CI 2.23-5.47). Participants who reported having an STI within the last 6 months had 60% lower odds of using ED PrEP (aOR = 0.4, 95% CI 0.2-0.72). The use of ED PrEP is a promising pathway for expanding PrEP due to its success and protection levels. Our studies indicated that educational background and behavior influence PrEP choice. Ensuring PrEP candidates and users have access to information about new PrEP types may increase uptake and support implementation efforts.

A Systematic Review and Narrative Synthesis of Factors Affecting Pre-exposure Prophylaxis Willingness Among Black Women for HIV Prevention

Pre-exposure prophylaxis (PrEP) can significantly reduce human immunodeficiency virus (HIV) transmission among Black women in the United States (U.S.), a group disproportionately affected by HIV. However, PrEP uptake in this HIV-vulnerable population is low. This review analyzes the factors influencing Black women's PrEP willingness using the Behavioral Model for Vulnerable Populations (BMVP). Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the Population, Intervention, Comparison, Outcome, Study Design (PICOS) framework, we conducted a systematic literature search and selected 24 peer-reviewed studies on PrEP willingness. Narrative synthesis revealed a heterogeneous landscape of the determinants affecting PrEP willingness among Black women, categorized into three main domains. Predisposing demographic and social factors included younger age, unmarried status, higher education, sexual or gender minority identity, trust in healthcare providers, and perceived HIV risk. Predisposing behavioral factors included condomless sex, multiple partners, and engagement in sex work. Socioeconomic status, health insurance, healthcare access, support systems, and structural challenges were identified as enabling factors influencing Black women's PrEP willingness. Finally, the perceived need domain and health-related factors influencing the perceived need for PrEP included a history of sexually transmitted infections (STI), intimate partner violence (IPV), and birth control interference. This study emphasizes the complexity of the barriers and facilitators of PrEP uptake and, thus, the need for tailored interventions and health strategies to promote its use. Addressing the interconnected individual, interpersonal, and structural determinants of PrEP access is crucial for improving PrEP willingness and thereby advancing health equity in this population.

Determinants of Potential HIV Vaccine Uptake Among Young Sexual Minoritized Men 17-24 Year Old

BACKGROUND

Failures in prior rollout of HIV prevention efforts have widened disparities in HIV incidence by race/ethnicity among young sexual minoritized men (YSMM). We hypothesized greater perceptions of medical mistrust would be associated with lower willingness to get an HIV vaccine, mediating the relationship between race/ethnicity and willingness to accept a future HIV vaccine.

METHODS

HIV-negative and unknown-status YSMM 17-24 years old (n = 229) recruited through social media and men-for-men networking apps completed online surveys from September 2021 to March 2022. Participants were asked about demographics, medical mistrust (health care-related sexual orientation stigma, health care-related race stigma, global medical mistrust, and trust in health care providers), and willingness to accept a future HIV vaccine.

RESULTS

Vaccine willingness was highest among White YSMM (96.0%) and lower among Black (71.0%), Latino (83.6%), and multiracial or another race/ethnicity YSMM (80.0%). Even after accounting for medical mistrust constructs as mediators, compared with White participants, Black participants had lower odds of being willing to accept a future HIV vaccine. Participants with greater trust in health care providers had higher odds of willingness to accept a future HIV vaccine.

DISCUSSION

Gaps in willingness to get an HIV vaccine are evident among YSMM by race/ethnicity, indicating potential further widening of disparities in HIV incidence when a vaccine becomes available without intervention.

PrEP Use in a US National Sample of Trans Men and Other Transmasculine People Who Have Sex With Men: A Longitudinal Analysis

INTRODUCTION

Efforts to improve pre-exposure prophylaxis (PrEP) uptake among gay men, transgender women, and Black cisgender women are evident across the United States, responding to epidemiologic data showing a disproportionate HIV burden in these communities. However, transgender men and other transmasculine people who have sex with men (TMSM)-those assigned female at birth who identify otherwise and have sex with cisgender men-are often excluded from these statistics. This community has unique vulnerabilities and prevention needs. National HIV prevention and planning has yet to include transgender men as a group with increased vulnerability to HIV seroconversion. This study follows a cohort of TMSM to characterize PrEP use longitudinally.

METHODS

Using data from a prospective US national cohort of TMSM not on PrEP, we analyzed annual PrEP uptake, discontinuation, and other HIV prevention measures over 24 months. We also used generalized estimating equations modeling to assess demographic, healthcare access, gender-affirming, and behavioral factors associated with PrEP uptake over time.

RESULTS

Our cohort of 196 TMSM was demographic and regionally diverse. 29% of our sample reported uptake of PrEP in 24 months, with about one-third of users discontinuing within 1 year. Health insurance, having had lower surgery, used post-exposure prophylaxis, or recently having a sexually transmitted infection were associated with increased odds of PrEP use.

CONCLUSION

We found low uptake of PrEP and high discontinuation rates in a US national sample of TMSM over 24 months, despite significant need for HIV prevention. It is vital to increase efforts and investments to support this neglected community.

PrEP your step: Implementing an online crowdsourcing contest to engage young people in HIV prevention in Washington DC, USA

HIV incidence among young people (Black and Latinx women and men who have sex with men ages 16-24 years), in the United States is high. Traditional top-down approaches for pre-exposure prophylaxis (PrEP) social marketing are not effectively reaching this population. Crowdsourcing is a promising approach to engaging young people in the development of innovative solutions to raise awareness and use of PrEP among those at highest risk of HIV. This study engaged young people in the design and evaluation of an online crowdsourcing contest to promote PrEP among Washington, DC youth. The contest used standard methods recommended by the World Health Organization and feedback from our community partners. Online recruitment using social media elicited online votes and survey responses. We analyzed cross-sectional surveys using descriptive statistics, and semi-structured interviews with contest participants using thematic coding to explore barriers and facilitators to contest engagement. Approximately 82% of entries were from young people in DC. A convenience sample of 181 people voted on their favorite crowdsourced PrEP messages and shared their awareness and attitudes about PrEP. The contest website received 2,500 unique visitors and 4,600 page views. Themes from semi-structured interviews (n = 16) included the need for more community engagement in developing PrEP messaging and positive attitudes towards crowdsourcing. Survey data (n = 887) showed that the crowdsourced messages were well-liked and resonated with the community. Most preferred to see PrEP messages in social media (23%), email (17%) and videos (14%). Approximately 70% of survey participants reported that after viewing the crowdsourced message they would talk to their sexual partner or medical provider (63%) about PrEP, use PrEP (58%), and learn more about PrEP (56%). Crowdsourced messages solicit substantial online viewership. More implementation research is needed to understand the public health impact of integrating social media, crowdsourcing, and community engagement to develop PrEP promotional messages.

Trends in Oral and Injectable HIV Preexposure Prophylaxis Prescriptions in the US, 2013-2023

This study examines the prescribing trends of 3 oral preexposure prophylaxis medications and a long-acting injectable option from 2013 to 2023.

Claims-Based Algorithm to Identify Pre-Exposure Prophylaxis Indications for Tenofovir Disoproxil Fumarate and Emtricitabine Prescriptions (2012-2014): Validation Study

BACKGROUND

To monitor the use of tenofovir disoproxil fumarate and emtricitabine (TDF/FTC) and related medicines for pre-exposure prophylaxis (PrEP) as HIV prevention using commercial pharmacy data, it is necessary to determine whether TDF/FTC prescriptions are used for PrEP or for some other clinical indication.

OBJECTIVE

This study aimed to validate an algorithm to distinguish the use of TDF/FTC for HIV prevention or infectious disease treatment.

METHODS

An algorithm was developed to identify whether TDF/FTC prescriptions were for PrEP or for other indications from large-scale administrative databases. The algorithm identifies TDF/FTC prescriptions and then excludes patients with International Classification of Diseases (ICD)-9 diagnostic codes, medications, or procedures that suggest indications other than for PrEP (eg, documentation of HIV infection, chronic hepatitis B, or use of TDF/FTC for postexposure prophylaxis). For evaluation, we collected data by clinician assessment of medical records for patients with TDF/FTC prescriptions and compared the assessed indication identified by the clinician review with the assessed indication identified by the algorithm. The algorithm was then applied and evaluated in a large, urban, community-based sexual health clinic.

RESULTS

The PrEP algorithm demonstrated high sensitivity and moderate specificity (99.6% and 49.6%) in the electronic medical record database and high sensitivity and specificity (99% and 87%) in data from the urban community health clinic.

CONCLUSIONS

The PrEP algorithm classified the indication for PrEP in most patients treated with TDF/FTC with sufficient accuracy to be useful for surveillance purposes. The methods described can serve as a basis for developing a robust and evolving case definition for antiretroviral prescriptions for HIV prevention purposes.

Understanding Typology of Preexposure Prophylaxis (PrEP) Persistence Trajectories Among Male PrEP Users in the United States

Introduction

Understanding longitudinal patterns of preexposure prophylaxis (PrEP) use among men who have sex with men could offer insights for developing efficient and timely interventions to promote PrEP persistence.

Setting

We extracted 2 years of pharmacy fill records for 4000 males who initiated PrEP in 2017 at a national chain pharmacy in the United States.

Methods

Group-based trajectory models were used to develop PrEP trajectory clusters, with periods of use defined based on optimal PrEP seroprotection probabilities (ie, PrEP use frequency ≥4 doses/week). Multinomial logistic regressions were used to evaluate the associations between sociodemographic covariates and identified trajectory group membership.

Results

We identified 4 distinct groups of PrEP persistence trajectories: (1) persistent use of PrEP throughout the period (persistent user), (2) brief use followed by sustained cessation of PrEP use (brief user), (3) PrEP use up to the mid-term followed by sustained cessation of PrEP use (mid-term user), and (4) PrEP use, followed by cessation and subsequent reinitiation (PrEP reinitiator). Persistent users and brief users accounted for 40.1% and 22.9% of the population, respectively, whereas mid-term users and reinitiators accounted for 18.9% and 18.2%, respectively. Older age at PrEP initiation, commercial insurance as the primary payer of PrEP, and use of specialty pharmacy were found to be associated with persistent PrEP use over the other patterns of nonpersistence.

Conclusions

Subgroups of PrEP users could benefit from PrEP persistence interventions that target specific timings of likely PrEP cessation or considerations of reinitiation.

Feasibility of Emergency Department-Initiated HIV Pre-Exposure Prophylaxis

Introduction

Pre-exposure prophylaxis (PrEP) for HIV-using antiretroviral medication in non-infected individuals to prevent HIV-has immense potential to slow the spread of the virus. However, uptake has been insufficient, and stark racial disparities exist in both HIV acquisition and PrEP usage, making PrEP access a health equity issue. A promising venue to engage high-risk populations in PrEP care is the emergency department (ED); however, existing ED PrEP initiatives have been costly or have had limited success. We hypothesize that two strategies could overcome these barriers: prescribing PrEP during an ED visit and providing patients with an initial supply of PrEP medication in the ED. Here, we describe the results of a qualitative study exploring multidisciplinary emergency clinicians and HIV clinicians' needs and views about the feasibility of such an initiative.

Methods

We conducted 22 semi-structured interviews with multidisciplinary clinicians from an urban, safety-net medical center in the ED and the on-site HIV clinic that provides PrEP services. We performed thematic analysis to summarize challenges and potential solutions described by participants.

Results

Participants' responses fell into three thematic categories: operational challenges; patient-level considerations; and potential impacts. Operational challenges highlighted the difficulty of PrEP initiation in a busy ED and clinician support needs. Patient-level considerations included the complex psychosocial needs of ED patients who could benefit from PrEP. Finally, participants anticipated that an ED-based PrEP initiation program could positively impact both individual patients and public health.

Conclusion

Interviews with emergency department and HIV clinic staff revealed important considerations and potential solutions for ED-initiated PrEP workflows. Clinicians in both specialties were enthusiastic about such an initiative, which could facilitate its success. This study lays the groundwork for the future design of an efficient and innovative workflow to leverage the ED as an essential entry point into HIV prevention services.

Brief communication: The cohort of women prescribed HIV PrEP at the Veterans Health Administration

The goal of this study was to describe the cohort of women prescribed PrEP at the Veterans Health Administration. We used a cross-sectional study of electronic health record data. We used descriptive statistics and calculated estimated average percent change by year of prescription. A total of 417 women were prescribed PrEP over the study period. The most substantial change over time in PrEP prescribing occurred among women aged 18-24, in Other race group, and in the Western US. Though PrEP prescribing increased since its approval, more research is needed to identify barriers and expand PrEP access for women Veterans.

Organizational readiness to implement bundled interventions to increase HIV linkage and retention in care and treatment: results from the Black Women First (BWF) initiative

BACKGROUND

Evidence-based and evidence-informed interventions designed to address gaps in the HIV care continuum have the potential to improve HIV care and treatment. However, inadequate organizational readiness can derail intervention uptake, prevent the integration of interventions, and contribute to suboptimal HIV treatment outcomes. This study sought to understand organizational readiness to implement bundled interventions for Black women with HIV and inform facilitators and barriers to implementation.

METHODS

We conducted a mixed methods readiness assessment across 12 sites participating in the Black Women First (BWF) initiative to gauge preparedness to implement bundled interventions. Readiness was assessed using the organizational readiness for implementing change (ORIC) scale, and two open-ended questions examined facilitators and barriers. Associations between participant and organizational level factors were evaluated using linear models with clustering by site at baseline, 6- and 12-months. Pre-implementation interviews were conducted with staff virtually and transcripts were managed in NVivo. Directed content analysis was used to explore implementation barriers and facilitators.

FINDINGS

Sites demonstrated high levels of organizational readiness at baseline; overall organizational readiness for implementing change (ORIC) (mean 56.4, median 59, interquartile range [IQR] 5) and subscales of the ORIC change efficacy (mean 32.4, median 35, IQR 4), change commitment (mean 24, median 25, IQR 1), which is consistent with willingness and capability to implement bundled interventions for Black women with HIV. Organizational readiness remained high at 6- and 12-month follow-up periods. Staff role was significantly associated with organizational readiness (p = 0.007), change efficacy (p = 0.006), and change commitment (p = 0.020) at 6 months. Qualitative analysis indicated strategic planning and assessment (e.g., team coordination and the development of workflows to support implementation); organizational change through network weaving across silos within the organization, and communications systems that engage external partners, as well as resources available for hiring and training, supported readiness. Collaborative leadership and organizational buy-in, staff motivation, and partnerships facilitated implementation processes.

CONCLUSIONS

Organizations in the BWF initiative have high levels of organizational readiness reflecting willingness and capability to implement bundled interventions for Black women with HIV. Future research should examine the relationship between readiness and clinical outcomes.

Longitudinal Impacts of Medicaid Expansion and Social Determinants of Health on PrEP Prevalence and PrEP-to-Need Ratio (PNR)

Despite its efficacy, pre-exposure prophylaxis (PrEP) for HIV has a low uptake, with many disparities remaining. This study aimed to assess the impact of Medicaid expansion and social determinants of health (SDOH) on PrEP prevalence and PrEP-to-need ratio (PnR) using county-level data from 2012 to 2022. Differences-in-differences regressions indicated that Medicaid expansion is associated with increased PnR but not PrEP prevalence. Linear regressions were conducted to evaluate the impact of county-level SDOH on PrEP outcomes. Rurality was associated with lower PnR and PrEP prevalence. Racial disparities were present, with areas with greater concentrations of non-Hispanic Black populations having lower PrEP prevalence and PnR. Greater concentrations of Hispanic populations were associated with lower PnR. Income inequality, socioeconomic status vulnerability, and primary care physician concentration were all associated with higher PnR. Medicaid expansion supports increasing PrEP use in the areas of greatest need. Efforts should be made to improve PrEP access, particularly in areas with high SDOH vulnerabilities.

Barriers and Facilitators to Acceptability and Uptake of Pre-Exposure Prophylaxis (PrEP) Among Black Women in the United States: a Systematic Review

OBJECTIVES

Pre-exposure prophylaxis (PrEP) provides a salient avenue to address the profound HIV-related health disparities that Black women in the United States face. This systematic review assessed the acceptability of PrEP within this population, and identified barriers and facilitators to its acceptability and uptake.

METHODS

We searched PubMed and Web of Science using 48 search input combinations; this produced 338 unique articles, 16 of which were included in the review.

RESULTS

We analyzed the results using the socio-ecological model (SEM). Findings indicate generally positive attitudes towards PrEP among Black women, although acceptance levels vary widely. Individual-level barriers included inadequate levels of PrEP awareness and knowledge, low HIV-risk perception, and concerns about adherence and side effects; interpersonal-level barriers were the influence of sexual and romantic partners and stigma from family; societal-level barriers included lack of PrEP marketing towards Black women, medical mistrust, cost, and structural violence. The main facilitators at the individual-level were PrEP education and information; at the interpersonal-level, distrust in sexual partners, healthcare provider encouragement, and social support; at the societal-level, PrEP accessibility, and affordability. No community-level barriers or facilitators were identified.

CONCLUSIONS

PrEP should be marketed directly to Black women in the US and campaigns should highlight this medication's effectiveness, accessibility, affordability, and safety. Medical mistrust must also be addressed to enable Black women to feel comfortable following their healthcare providers' advice regarding PrEP.

Trajectories of Adherence to Oral Pre-exposure Prophylaxis and Risks of HIV and Sexually Transmitted Infections

Background

Pre-exposure prophylaxis (PrEP) effectiveness is highly dependent on medication adherence, which is associated with differential HIV risks and possibly sexually transmitted infection (STI).

Methods

This retrospective cohort study of PrEP users (01/01/2012-12/31/2021) used the MarketScan database of commercially insured enrollees to examine PrEP adherence trajectory groups' associations with HIV and STI acquisition risks. Distinct PrEP adherence trajectories were identified by group-based trajectory modeling among individuals who used oral PrEP. The primary outcome was HIV acquisition incidence, and secondary was STI rate, compared among trajectory groups. Inverse probability treatment weighting time-varying Cox proportional hazards models assessed HIV acquisition, and Poisson regression models assessed STI.

Results

Among 23 258 oral PrEP users, 4 distinct PrEP adherence patterns were identified: minimal use (10.5% of the cohort), rapidly declining (25.4%), gradually declining (24.3%), and consistently high (39.8%). Compared with the minimal use group, the gradually declining (adjusted hazard ratio [AHR], 0.53; 95% CI, 0.31-0.90) and consistently high (AHR, 0.50; 95% CI, 0.30-0.84) PrEP adherence groups showed decreased HIV incidence risks. Compared with the minimal use group, the rapidly declining (adjusted incidence rate ratio [AIRR], 1.35; 95% CI, 1.07-1.72), gradually declining (AIRR, 1.73; 95% CI, 1.38-2.18), and consistently high (AIRR, 2.06; 95% CI, 1.64-2.58) groups were associated with increased STI risk.

Conclusions

These findings underscore the benefits of continuing and remaining adherent to PrEP and may also inform public health strategies, clinical guidelines, and interventions aimed at maximizing the effectiveness of PrEP in reducing new HIV infections while developing targeted strategies to prevent STIs with PrEP use.

A mixed-methods evaluation of an HIV pre-exposure prophylaxis educational intervention for healthcare providers in a NYC safety-net hospital-based obstetrics and gynecology clinic

Cisgender women and transgender men are less likely to be assessed for PrEP eligibility, prescribed PrEP, or retained in PrEP care. Thus, this pilot PrEP educational intervention was tailored for healthcare providers (HCPs) in obstetrics/gynecology who provide care to cisgender women and transgender men in an academically-affiliated, public hospital women's health clinic. The three-lecture educational curriculum designed for HCPs focused on PrEP eligibility and counseling, formulations and adherence, and prescription and payment assistance programs. Pre- and post-intervention surveys assessed HCP knowledge and barriers to PrEP counseling and prescription. Among n = 49 participants (mean age = 32.8 years; 85.7% cisgender women, mean years practicing = 4.2 years) pre-intervention, 8.7% had prior PrEP training and 61.2% felt very/somewhat uncomfortable prescribing PrEP. Post-intervention, knowledge of PrEP contraindications, eligibility, follow-up care, and assistance programs all increased. HCPs identified key barriers to PrEP care including lack of a dedicated PrEP navigator, culturally and linguistically appropriate patient materials on PrEP resources/costs, and PrEP-related content integrated into EHRs. Ongoing PrEP educational sessions can provide opportunities to practice PrEP counseling, including information on financial assistance. At the institutional level, incorporating PrEP screening in routine clinical practice via EMR prompts, facilitating PrEP medication monitoring, and enhancing telehealth for follow-up care could enhance PrEP prescription.

Pre-exposure Prophylaxis (PrEP) implementation among latino MSM: a qualitative scoping review of implementation determinants and change methods

INTRODUCTION

The increasing rates of HIV among Latino men who have sex with men (MSM) necessitate innovative and rigorous studies to evaluate prevention and treatment strategies. Pre-exposure prophylaxis (PrEP) is a highly effective tool in preventing HIV acquisition and plays a crucial role in the Ending the HIV Epidemic in the U.S. initiative. However, there is a scarcity of PrEP research specifically focused on Latino MSM, and the factors influencing its implementation remain largely unknown.

METHODS

To address this gap, we conducted a comprehensive review exploring the determinants (barriers and facilitators) of PrEP implementation among Latino MSM, as well as the change methods (implementation strategies and adjunctive interventions) that have been evaluated to promote its adoption. Our review encompassed 43 peer-reviewed articles examining determinants and four articles assessing change methods. Determinants were coded using the updated Consolidated Framework for Implementation Research (CFIR 2.0) to understand the multilevel barriers and facilitators associated with implementation.

RESULTS

The majority of research has focused on PrEP recipients (i.e., patients), primarily examining their awareness and willingness to use PrEP. Fewer studies have explored the factors influencing clinicians and service delivery systems. Additionally, the evaluation of change methods to enhance clinician adoption and adherence to PrEP and recipient adherence to PrEP has been limited.

CONCLUSION

It is evident that there is a need for culturally adapted strategies tailored specifically for Latino MSM, as the current literature remains largely unexplored in this regard. By incorporating principles from implementation science, we can gain a clearer understanding of the knowledge, skills, and roles necessary for effective cultural adaptations. Future research should emphasize factors influencing implementation from a clinician standpoint and focus on innovative change methods to increase PrEP awareness, reach, adoption, and sustained adherence among Latino MSM.

Culturally Targeted Video Intervention to Increase PrEP Use Intentions Among Latinx Sexual Minority Men: A Pilot Randomized Controlled Trial

Background: Latinx sexual minority men experience the greatest human immunodeficiency virus (HIV) burden in the United States. Pre-exposure prophylaxis (PrEP) is the most effective HIV prevention tool available, however, PrEP uptake remains low among this group. Methods: This two-arm pilot randomized controlled trial study aimed to assess the feasibility and preliminary efficacy of delivering an online culturally targeted video intervention that aims to increase PrEP uptake intentions among Latinx sexual minority men. The intervention group received a culturally targeted video that contained the same PrEP information as the control group and incorporated positive aspects of Latinx masculinity (i.e., caballerismo). Participants were recruited through Amazon's MTurk crowd-sourcing platform. A total of twenty-five participants met the study inclusion criteria (N = 25). Results: The control group had a higher mean PrEP intentions score (M: 3.3, 95% CI: 2.7-3.9) when compared with the intervention group. A moderate, negative, linear correlation was observed between machismo and PrEP intention scores (r = -.34). In contrast, a small, positive correlation was found between caballerismo and PrEP intentions (r = .19). Conclusions: While the culturally targeted video intervention did not increase PrEP use intentions, the study highlights the importance of understanding and addressing cultural factors such as Latin masculinity.

Assessing Structural Racism and Discrimination Along the Pre-exposure Prophylaxis Continuum: A Systematic Review

Structural racism and discrimination (SRD) is deeply embedded across U.S. healthcare institutions, but its impact on health outcomes is challenging to assess. The purpose of this systematic literature review is to understand the impact of SRD on pre-exposure prophylaxis (PrEP) care continuum outcomes across U.S. populations who could benefit from HIV prevention. Guided by PRISMA guidelines, we conducted a systematic review of the published literature up to September 2023 using PubMed and PsycInfo and included peer-reviewed articles meeting inclusion criteria. At least two authors independently screened studies, performed quality assessments, and abstracted data relevant to the topic. Exposure variables included race/ethnicity and any level of SRD (interpersonal, intra- and extra-organizational SRD). Outcomes consisted of any steps of the PrEP care continuum. A total of 66 studies met inclusion criteria and demonstrated the negative impact of SRD on the PrEP care continuum. At the interpersonal level, medical mistrust (i.e., lack of trust in medical organizations and professionals rooted from current or historical practices of discrimination) was negatively associated with almost all the steps across the PrEP care continuum: individuals with medical mistrust were less likely to have PrEP knowledge, adhere to PrEP care, and be retained in care. At the intra-organizational level, PrEP prescription was lower for Black patients due to healthcare provider perception of higher sex-risk behaviors. At the extra-organizational level, factors such as homelessness, low socioeconomic status, and incarceration were associated with decreased PrEP uptake. On the other hand, healthcare provider trust, higher patient education, and access to health insurance were associated with increased PrEP use and retention in care. In addition, analyses using race/ethnicity as an exposure did not consistently show associations with PrEP continuum outcomes. We found that SRD has a negative impact at all steps of the PrEP care continuum. Our results suggest that when assessing the effects of race/ethnicity without the context of SRD, certain relationships and associations are missed. Addressing multi-level barriers related to SRD are needed to reduce HIV transmission and promote health equity.

Self-Perception of Risk for HIV Acquisition and Calculated Risk for HIV Acquisition Among Active Duty Air Force Members With Newly Diagnosed HIV Infection

INTRODUCTION

There have been nearly 1,600 new diagnoses of Human Immunodeficiency Virus (HIV) across the US Armed Forces between 2017 and 2022. While treatment has improved overall survival, self-perception of acquiring HIV may not align with actual risk of acquiring HIV, thus slowing diagnosis and treatment. We aim to evaluate self-perceived risk (SPR) versus calculated risk (CR) of HIV infection in US Air Force (USAF) members with incident HIV diagnosis.

METHODS

All USAF members with new HIV diagnosis evaluated at a specialty care military medical center between January 2015 and March 2020 with case report forms were included (n = 142). SPR was compared to CR using the Denver HIV Risk Score (DHRS). The study was approved by the Army Public Health Center's Public Health Review Board (#14-311) and the Walter Reed Army Institute of Research Human Subjects Protection Branch (#1861E).

RESULTS

Patients were predominantly male (98%), with a median age of 26 (IQR 22-30) years, and the majority (85%) reported same-sex partners. Most patients reported a low SPR (n = 78; 55%). A higher proportion of low SPR patients were married or partnered than high SPR patients (29% versus 14%; P = 0.04). Both groups had median DHRS scores in the highest risk category with similar results by reason for HIV screening.

CONCLUSION

The majority of USAF members with incident HIV infection reported a low SPR despite risk factors and CRs identical to high SPR patients. In order to inform HIV prevention strategies in the military, further efforts are needed to educate the military population and providers about HIV risk perception.

Using the andersen healthcare utilization model to assess willingness to screen for prep in pharmacy-based settings among cisgender sexually minoritized men: results from the 2020 american men's internet survey

BACKGROUND

Pre-exposure prophylaxis (PrEP) to prevent HIV is severely underutilized among sexually minoritized men (SMM). Inequitable access to PrEP-prescribing facilities and providers is a critical barrier to PrEP uptake among SMM. Integrating HIV prevention services, such as PrEP screening, into pharmacy-based settings is a viable solution to addressing HIV inequities in the US. We aimed to examine willingness to obtain PrEP screening in a pharmacy and its associated correlates, leveraging Andersen's Healthcare Utilization Model (AHUM), among a national sample of SMM in the U.S.

METHODS

Data from the 2020 American Men's Internet Survey, an annual online survey among SMM, were analyzed. Drawing on AHUM-related constructs, we used a modified stepwise Poisson regression with robust variance estimates to examine differences in willingness to screen for PrEP in a pharmacy. Estimated prevalence ratios (PR) were calculated with 95% confidence intervals (CI95%).

RESULTS

Out of 10,816 men, most (76%) were willing to screen for PrEP in a pharmacy. Participants were more willing to screen for PrEP in a pharmacy if they (1) had a general willingness to use PrEP (PR = 1.52; CI95% =1.45, 1.59); (2) felt comfortable speaking with pharmacy staff about PrEP (PR = 2.71; CI95% =2.47, 2.98); and (3) had HIV-related concerns (PR = 1.04; CI95% =1.02, 1.06). There were no observed differences in men's willingness to screen for PrEP in a pharmacy by race/ethnicity, education level, annual household income, nor insurance status.

CONCLUSIONS

Strategically offering PrEP screening in pharmacies could mitigate access-related barriers to HIV prevention services among SMM, particularly across various sociodemographic domains. Importantly, this approach has vitally important implications for addressing broader inequities in HIV prevention. Future studies should examine strategies to successfully integrate PrEP screenings in pharmacies among diverse populations, especially among those at elevated risk for HIV.

Ameliorating Racial Disparities in HIV Prevention via a Nurse-Led, AI-Enhanced Program for Pre-Exposure Prophylaxis Utilization Among Black Cisgender Women: Protocol for a Mixed Methods Study

BACKGROUND

HIV pre-exposure prophylaxis (PrEP) is a critical biomedical strategy to prevent HIV transmission among cisgender women. Despite its proven effectiveness, Black cisgender women remain significantly underrepresented throughout the PrEP care continuum, facing barriers such as limited access to care, medical mistrust, and intersectional racial or HIV stigma. Addressing these disparities is vital to improving HIV prevention outcomes within this community. On the other hand, nurse practitioners (NPs) play a pivotal role in PrEP utilization but are underrepresented due to a lack of awareness, a lack of human resources, and insufficient support. Equipped with the rapid evolution of artificial intelligence (AI) and advanced large language models, chatbots effectively facilitate health care communication and linkage to care in various domains, including HIV prevention and PrEP care.

OBJECTIVE

Our study harnesses NPs' holistic care capabilities and the power of AI through natural language processing algorithms, providing targeted, patient-centered facilitation for PrEP care. Our overarching goal is to create a nurse-led, stakeholder-inclusive, and AI-powered program to facilitate PrEP utilization among Black cisgender women, ultimately enhancing HIV prevention efforts in this vulnerable group in 3 phases. This project aims to mitigate health disparities and advance innovative, technology-based solutions.

METHODS

The study uses a mixed methods design involving semistructured interviews with key stakeholders, including 50 PrEP-eligible Black women, 10 NPs, and a community advisory board representing various socioeconomic backgrounds. The AI-powered chatbot is developed using HumanX technology and SmartBot360's Health Insurance Portability and Accountability Act-compliant framework to ensure data privacy and security. The study spans 18 months and consists of 3 phases: exploration, development, and evaluation.

RESULTS

As of May 2024, the institutional review board protocol for phase 1 has been approved. We plan to start recruitment for Black cisgender women and NPs in September 2024, with the aim to collect information to understand their preferences regarding chatbot development. While institutional review board approval for phases 2 and 3 is still in progress, we have made significant strides in networking for participant recruitment. We plan to conduct data collection soon, and further updates on the recruitment and data collection progress will be provided as the study advances.

CONCLUSIONS

The AI-powered chatbot offers a novel approach to improving PrEP care utilization among Black cisgender women, with opportunities to reduce barriers to care and facilitate a stigma-free environment. However, challenges remain regarding health equity and the digital divide, emphasizing the need for culturally competent design and robust data privacy protocols. The implications of this study extend beyond PrEP care, presenting a scalable model that can address broader health disparities.

Long-Term HIV Pre-Exposure Prophylaxis Persistence and Reinitiation in Connecticut from 2012 to 2018

HIV pre-exposure prophylaxis (PrEP) is a highly effective biomedical prevention for HIV infections. PrEP persistence is critical to achieving optimal protection against HIV infection. However, little is known about PrEP persistence in the United States. This study utilized the Connecticut All-Payer Claims Database (APCD) to identify PrEP persistence among patients who filled their PrEP prescriptions in the state. The authors identified 1,576 PrEP patients who picked up PrEP prescriptions and extracted medical and pharmacy claims to evaluate a longitudinal cohort during 2012-2018 based on the Connecticut APCD. Patients who did not pick up medication for one consecutive month (ie, 30 days) were defined as discontinuing PrEP. Kaplan-Meier Survival Curve and proportional hazard regression were used to describe PrEP persistence. Of the 1,576 patients who picked up PrEP prescriptions, the median age was 32.0 (interquartile range [IQR]: 22.0-44.0). The majority were male individuals (93%). Of 1,040 patients who discontinued PrEP, 702 (67.5%) restarted PrEP at least once. The median time of PrEP persistence was 3 months (IQR: 1-6 months) for initial PrEP use. The median time on PrEP was also around 3 months in the following episodes of PrEP use. Being female, being on parent's insurance, and having high co-pays were associated with shorter periods of PrEP persistence. PrEP persistence was low among patients who picked up PrEP prescriptions. Although many patients restarted PrEP, persistence remained low during follow-up PrEP use and possibly led to periods of increased HIV risk. Effective interventions are needed to improve PrEP persistence and reduce HIV incidence.

HIV Prevention Intervention-related Research with Adult, Sexual Minority Hispanic Men in the United States: A Systematic Review

The systematic review describes aims to synthesize the HIV prevention intervention-related research conducted among adult, US sexual minority Hispanic men since 2012. Following PRISMA guidelines, 15 articles representing 14 studies were included in the review: 4 randomized controlled trials, 5 pilots, and 5 formative projects. Two interventions had PrEP-related outcomes whereas 7 focused on behavioral (e.g., condoms, testing) and/or educational outcomes. Few studies used digital health. All but one study was theoretically guided. Community engagement was a common and important thread in the included studies, with community-based participatory research being the most prevalent framework. The inclusion of cultural factors varied widely, as did the availability of Spanish language or bilingual study materials. Future research opportunities are discussed and recommendations to bolster HIV prevention interventions (e.g., tailoring) are presented. These include the need for greater integration of cultural factors (e.g., nuances related to the heterogeneity of Hispanic subgroups) and mitigating critical barriers to help improve uptake of evidence-based strategies in this population.

Predictors of PrEP Retention and Attrition in an Urban Publicly Funded Safety-net Specialty Clinic

Pre-exposure prophylaxis (PrEP) is an effective tool for human immunodeficiency virus (HIV) prevention. The purpose of this study is to identify correlates of PrEP retention using patient data from an urban, publicly funded safety-net clinic in Washington, DC. Cox proportional hazards regression, logistical regression, and survival curves were used to assess the association of age, gender, race/ethnicity, insurance, number of partners, and sexually transmitted infection (STI) diagnosis at PrEP initiation with time on PrEP. From August 2016-December 2020, 1,126 people were prescribed PrEP - patients were mostly Black (44.8%) or Latinx (30.4%) and identified as cisgender men (84.6%). Half had no insurance (49.1%), with the remaining patients reporting private (28.9%) or public (21.5%) insurance. Age at PrEP prescription ranged from 15 to 66 with 80% being 20 to 39 years. For the 87.7% (n = 987) of patients who discontinued PrEP, mean PrEP time was 158 days and median was 28 days. The highest rates of discontinuation were observed within the first month with 44.3% discontinuing by day 30, 52.3% by 3 months, and 73.2% by 1 year. Cisgender women, transgender persons, and those younger than 30 years were more likely to discontinue PrEP. Latinx and patients with less than 3 male partners in the last 90 days were less likely to discontinue PrEP. We demonstrated a high level of PrEP uptake among populations disproportionally affected by HIV. Future analyses are needed to examine ways of reducing barriers to PrEP initiation and improving PrEP adherence.

Acceptability and appropriateness of information sessions to increase knowledge and awareness of PrEP and TelePrEP among Latina Women

Women of color are disproportionately impacted by HIV. Although PrEP effectively prevents HIV infection, PrEP coverage and knowledge remain low in this population. To address barriers to PrEP, we implemented women-centered and culturally appropriate Information Sessions (IS) delivered by staff from the population they serve to increase knowledge, awareness, and use of PrEP through telemedicine (e.g., PlushCare). Our analysis focuses on Latina women (LW) participants, given the dearth of literature dedicated to the needs of LW. We partnered with a woman-led community-based organization (CBO) to implement the strategy with LW clients. Health educators conducted 26 IS with 94 LW (20 in Spanish and 6 in English). Participants who completed the IS were invited for interviews to assess the acceptability and appropriateness of the IS to increase knowledge and awareness of PrEP and PlushCare. Four themes emerged from the thematic analysis: (1) IS increased knowledge and awareness of PrEP and PlushCare; (2) perceived acceptability and appropriateness of IS; (3) insufficient reasons to warrant use of PrEP; and (4) positive attitudes about PlushCare. Our findings suggest that a women-centered and culturally appropriate IS implemented through a trusted, woman-led CBO is an acceptable and appropriate implementation strategy to inform LW about PrEP.

Missed Opportunity or Cause for Concern? Methamphetamine Use Is Associated With Greater Interest in Event-Driven PrEP Among Sexual Minority Men

Our study assessed the association between methamphetamine (i.e., crystal meth, CM) use and awareness and interest in event-driven (ED) PrEP among HIV-negative and those with unknown serostatus cisgender males and transgender people. We performed log-binomial regression analysis to predict awareness (i.e., having heard of ED PrEP) and being interested in ED PrEP. We found that participants who recently used CM were less likely to know of ED PrEP (aPR = 0.83, 95% CI [0.69, 0.99]) but more interested in ED PrEP (aPR = 1.12, 95% CI [1.01, 1.30]), after accounting for demographic and HIV-related behaviors. Opportunities to expand PrEP uptake and improve adherence among individuals who report CM use are essential to impact the HIV epidemic significantly. Continued research on the needs and best practices to work with this community is needed to ensure a successful rollout and implementation of ED PrEP.

CDC Prioritizes HIV Prevention and Treatment to Reduce HIV Disparities Among Cis-Gender Black Women

To succeed in ending the HIV epidemic in the United States, the Centers for Disease Control and Prevention (CDC) focuses on delivering combinations of scientifically proven, cost-effective, and scalable interventions to priority populations. Systemic factors continue to contribute to persistent health disparities and disproportionately higher rates of HIV diagnosis in some communities. The National HIV/AIDS Strategy has designated cis-gender Black women (CgBW) as a priority population to address the racial and ethnic inequities in HIV. This report presents the portfolio of projects, programs, and initiatives funded by the CDC's Division of HIV Prevention (DHP) to address disparities in HIV and improve health and QOL among CgBW. These funded activities include the development, planning, and implementation of HIV prevention programs, mass media campaigns, and behavioral interventions focused on CgBW. This report also summarizes DHP's community engagement, capacity building, and partnership efforts, and highlights research and surveillance activities focusing on CgBW. Finally, this report outlines future directions for CDC's efforts to improve access to HIV testing, treatment, and prevention for CgBW in the United States.

The Impact of Stigma and Sexual Identity on PrEP Awareness and Use Among At-Risk Men Who Have Sex With Men in Four U.S. Cities (HPTN 078)

Persistent pre-exposure prophylaxis (PrEP) use reduces the risk of HIV infection, yet uptake lags among those with the greatest need. Sexual identity stigma may be a significant barrier to PrEP awareness and use among high-risk communities. The primary aim of this study was to determine whether sexual identity was related to PrEP awareness and use. This multi-site HIV Prevention Trials Network (HPTN) study (HPTN 078) focuses on men who have sex with men (MSM) (n=335) who were HIV-negative at screening. The majority of participants were non-white (62.1%), younger than 35 (57.9%), single (79.1%), and aware of PrEP, yet had never taken PrEP (52.5%). Participants completed questionnaires including sexual history and identity; lesbian, gay, bisexual, transgender, queer (LGBTQ) community engagement; PrEP awareness and use; and several measures of sexual identity stigma including family and friend stigma, general societal stigma, and anticipated healthcare stigma. Univariate and multinomial logistic regression models helped to determine factors associated with PrEP awareness and use. There were stark disparities in PrEP awareness comparing Black and White participants; 50% of Black participants reported being PrEP unaware vs 11.8% of White participants. In this sample, gay sexual identity (compared to bisexual identity) was associated with increased PrEP awareness (AOR 6.66) and use (AOR 16.9). Additionally, 29% of the association between sexual orientation and PrEP use was mediated through internalized stigma. Given low PrEP uptake among MSM, interventions that address sexual identity stigma may motivate greater PrEP uptake.

Effectiveness of a culturally tailored HIV intervention in promoting PrEP among black women who use drugs in community supervision programs in New York City: a randomized clinical trial

BACKGROUND

In the U.S. there are significant racial and gender disparities in the uptake of pre-exposure prophylaxis (PrEP). Black Americans represented 14% of PrEP users in 2022, but accounted for 42% of new HIV diagnoses in 2021 and in the South, Black people represented 48% of new HIV diagnoses in 2021 but only 21% of PrEP users in 2022. Women who use drugs may be even less likely than women who do not use drugs have initiated PrEP. Moreover, women involved in community supervision programs (CSP) are less likely to initiate or use PrEP, More PrEP interventions that focus on Black women with recent history of drug use in CSPs are needed to reduce inequities in PrEP uptake.

METHODS

We conducted a secondary analysis from a randomized clinical trial with a sub-sample (n = 336) of the total (N = 352) participants from the parent study (E-WORTH), who tested HIV negative at baseline were considered PrEP-eligible. Black women were recruited from CSPs in New York City (NYC), with recent substance use. Participants were randomized to either E-WORTH (n = 172) an HIV testing plus, receive a 5-session, culturally-tailored, group-based HIV prevention intervention, versus an HIV testing control group (n = 180). The 5 sessions included an introduction to PrEP and access. This paper reports outcomes on improved awareness of PrEP, willingness to use PrEP, and PrEP uptake over the 12-month follow-up period. HIV outcomes are reported in a previous paper.

RESULTS

Compared to control participants, participants in this study assigned to E-WORTH had significantly greater odds of being aware of PrEP as a biomedical HIV prevention strategy (OR = 3.25, 95% CI = 1.64-6.46, p = 0.001), and indicated a greater willingness to use PrEP as an HIV prevention method (b = 0.19, 95% CI = 0.06-0.32, p = 0.004) over the entire 12-month follow-up period.

CONCLUSIONS

These findings underscore the effectiveness of a culturally-tailored intervention for Black women in CSP settings in increasing awareness, and intention to initiate PrEP. Low uptake of PrEP in both arms highlight the need for providing more robust PrEP-on-demand strategies that are integrated into other services such as substance abuse treatment.

Preferences for a community pharmacy-based pre-exposure prophylaxis (PrEP) delivery program: A discrete choice experiment

BACKGROUND

Community pharmacies are ideal venues for pre-exposure prophylaxis (PrEP) delivery. Pharmacists and pharmacy-based PrEP delivery programs have the potential to improve access.

OBJECTIVES

This study elicited preferences for attributes of a hypothetical community pharmacy-based PrEP delivery program among US men who have sex with men (MSM) and assessed predictors of their preferences.

METHODS

Data were collected via a cross-sectional anonymous survey of US MSM, who were aged 18-65 years, not transgender, reported HIV status negative/unknown, and PrEP eligible. A discrete choice experiment was conducted with seven attributes of a pharmacy-based PrEP program: initial PrEP eligibility screening mode, location for human immunodeficiency virus (HIV) tests, timing for HIV test results, PrEP decision-making style, location of PrEP consultations, PrEP medication fill method, and mode for ongoing monitoring. Latent class analysis was performed to analyze preference heterogeneity. Multinomial logistic regression assessed predictors of latent class membership.

RESULTS

This study included 390 MSM. Time to receive HIV test results was the most important attribute; receiving results on the same day had the highest preference. The next most important attribute was PrEP screening mode; online questionnaires were the most preferred. Respondents' preferences clustered into four classes: 1) "Same day results and online monitoring" (SDROM) group (63.1%), 2) "Consumerist decision-making" (CDM) group (16.2%), 3) "Self-screening (online questionnaire)" (SOQ) group (11.3%), and 4) "Same day results preferring" (SDRP) group (9.5%). Hispanic MSM (adjusted odds ratio [aOR] =0.31, 95% confidence interval [CI] [0.12-0.84], P = 0.020), MSM of other races (aOR=0.38, 95% CI [0.15-0.97], P = 0.044) vs. White MSM; and those having a sexually transmitted disease recently (aOR=0.37, 95% CI [0.16-0.85], P = 0.018), had lower odds of being in the CDM group vs. the SDROM group.

CONCLUSIONS

MSM's preferences for a pharmacy-based PrEP program are heterogeneous. Same day results for HIV tests and online PrEP screening are key components when designing a community pharmacy-based PrEP program.

Access to PrEP and other sexual health services for cisgender women in the United States: a review of state policy and Medicaid expansion

Pre-exposure prophylaxis (PrEP) has the potential to prevent new HIV infections, but it is unclear how state policies governing sexual and reproductive health services (SRH) impact access for cisgender women. The objective of this review is to identify barriers to PrEP access for cisgender women in the United States. Using the CDC Atlas Program, 20 states with the highest HIV incidence among cisgender women were included in this analysis. Through a search conducted in May-July 2022 of CDC, PrEPWatch.org, and other State Department and Insurance websites, Medicaid expansion status, pharmacist PrEP prescribing laws, financial support programs, and Traditional Medicaid coverage of PrEP, HIV testing, and emergency contraception were reviewed. Of the included states, nearly half did not expand Medicaid at the state level. Emergency contraception and HIV testing was covered under Traditional Medicaid for almost all included states, but insurance stipulations and eligibility requirements remain. Although PrEP is covered under all Traditional Medicaid plans, six states require pre-authorization. Three states have HIV testing mandates, four allow pharmacists to prescribe PrEP and six have financial support programs to cover the cost of PrEP. Medicaid expansion, pre-authorization requirements for PrEP prescriptions and emergency contraception, and limitations on pharmacist prescribing abilities were identified as barriers to SRH access for cisgender women. Medicaid expansion should be prioritized as an approach to expanding access to HIV prevention services at the state level.

Racial inequities in HIV incidence among men who have sex with men prior to and amidst an Ending the HIV Epidemic initiative

OBJECTIVE

The aim of this study was to examine trends in HIV incidence among men who have sex with men (MSM) relative to the scale up of Ending the HIV Epidemic (EHE) initiatives, including biomedical prevention strategies, and to describe racial inequities over time.

DESIGN

A cross-sectional study, matching annual cohorts of New York City (NYC) Sexual Health Clinic (SHC) patients from 2010 to 2018 to the citywide HIV registry to identify seroconversions during 1 year of follow-up, through 2019.

METHODS

We examined HIV incidence for each annual cohort of MSM using diagnoses within 1 year after last negative HIV test. We calculated incidence rates and rate ratios (IRR) pooled across 3-year intervals (2010-2012, 2013-2015, 2016-2018) by race/ethnicity, age, neighborhood poverty level, recent STI diagnosis, and condom use during anal sex.

RESULTS

There were 36 156 study visits among MSM attending NYC SHCs, including 37% among White MSM and 63% among MSM of color. From 2010 to 2018, HIV incidence decreased overall from 2.82 to 0.82/100 person-years, and among all race/ethnicity, age, poverty, STI, and condom use subgroups. For 2010-2012 vs. 2016-2018, adjusted IRRs (95% CI) increased for Black MSM [1.8 (1.3-2.6) vs. 6.0 (3.5-10.2)], Latino MSM [1.4 (1.0-2.0) vs. 4.0 (2.3-6.8)], and MSM of other races [1.0 (0.6-1.7) vs. 2.5 (1.3-4.9)] compared with White MSM. Black and Latino MSM seroconverted at significantly higher rates than White MSM in the same age groups and neighborhood poverty level.

CONCLUSION

Despite decreases in HIV incidence among MSM, racial inequities were exacerbated over time. Addressing structural factors that impact racial inequities in risk of HIV should undergird EHE initiatives.

The health equity implications of the Health Resources and Services Administration's Ryan White HIV/AIDS Program

OBJECTIVE

Investigate the role of the Ryan White HIV/AIDS Program (RWHAP) - which funds services for vulnerable and historically disadvantaged populations with HIV - in reducing health inequities among people with HIV over a 10-year horizon.

DESIGN

We use an agent-based microsimulation model to incorporate the complexity of the program and long-time horizon.

METHODS

We use a composite measure (the Theil index) to evaluate the health equity implications of the RWHAP for each of four subgroups (based on race and ethnicity, age, gender, and HIV transmission category) and two outcomes (probability of being in care and treatment and probability of being virally suppressed). We compare results with the RWHAP fully funded versus a counterfactual scenario, in which the medical and support services funded by the RWHAP are not available.

RESULTS

The model indicates the RWHAP will improve health equity across all demographic subgroups and outcomes over a 10-year horizon. In Year 10, the Theil index for race and ethnicity is 99% lower for both outcomes under the RWHAP compared to the non-RWHAP scenario; 71-93% lower across HIV transmission categories; 31-44% lower for age; and 73-75% lower for gender.

CONCLUSION

Given the large number of people served by the RWHAP and our findings on its impact on equity, the RWHAP represents an important vehicle for achieving the health equity goals of the National HIV/AIDS Strategy (2022-2025) and the Ending the HIV Epidemic Initiative goal of reducing new infections by 90% by 2030.

The impact of intimate partner violence on PrEP adherence among U.S. Cisgender women at risk for HIV

BACKGROUND

Cisgender women account for 1 in 5 new HIV infections in the United States, yet remain under-engaged in HIV prevention. Women experiencing violence face risk for HIV due to biological and behavioral mechanisms, and barriers to prevention, such as challenges to Pre-Exposure Prophylaxis for HIV Prevention (PrEP) adherence. In this analysis, we aim to characterize intimate partner violence (IPV) among cisgender heterosexual women enrolled in a PrEP demonstration project and assess the associations with PrEP adherence.

METHODS

Adherence Enhancement Guided by Individualized Texting and Drug Levels (AEGiS) was a 48-week single-arm open-label study of PrEP adherence in HIV-negative cisgender women in Southern California (N = 130) offered daily tenofovir disoproxil fumarate/emtricitabine (TDF/FTC). From 6/2016 to 10/2018, women completed a survey reporting HIV risk behavior and experiences of any IPV (past 90-days) and IPV sub-types (past-year, lifetime) and biological testing for HIV/STIs at baseline, and concentrations of tenofovir-diphosphate (TFV-DP) in dried blood spots at weeks 4, 12, 24, 36, and 48. Outcomes were TFV-DP concentrations consistent with ≥ 4 or ≥ 6 doses/week at one or multiple visits. Multivariable logistic regression models were conducted to examine associations.

RESULTS

Past-90-day IPV was reported by 34.4% of participants, and past-year and lifetime subtypes reported by 11.5-41.5%, and 21.5-52.3%, respectively. Women who engaged in sex work and Black women were significantly more likely to report IPV than others. Lifetime physical IPV was negatively associated with adherence at ≥ 4 doses/week at ≥ 3 of 5 visits, while other relationships with any IPV and IPV sub-types were variable.

CONCLUSION

IPV is an indication for PrEP and important indicator of HIV risk; our findings suggest that physical IPV may also negatively impact long-term PrEP adherence.

Examining the Intersection of Ethnoracial Disparities and HIV Status in Substance Use Risks among U.S. Adults

Black/African American and Hispanic Americans experience significant HIV-related disparities. Substance use might be a contributing factor to these disparities, but there is limited research on this topic. This study investigated various substance use risks by HIV status and race/ethnicity (Black, Hispanic, White) among U.S. adults. We used data from the 2005-2019 National Survey on Drug Use and Health (N = 541,921). In each racial/ethnic group, the prevalence rates of past-year and past-month tobacco, alcohol, cannabis, and cocaine use, and past-year alcohol and illicit drug use disorders were estimated by HIV status. A series of logistic regressions with the interaction term of HIV x race/ethnicity were performed to examine race/ethnicity's moderating effect on the HIV-substance use associations, while controlling for sociodemographic factors and survey year. Moderation analysis showed that HIV status's association with the risks of past-year tobacco use (AOR = 1.67, 95% CI = 1.01-2.75), past-year cocaine use (AOR = 3.80, 95% CI = 1.91-7.57), past-month cocaine use (AOR = 5.34, 95% CI = 2.10-13.60), and past-year alcohol use disorder (AOR = 2.52, 95% CI = 1.29-4.92) differed significantly between Black and White adults. Between the Hispanic and White groups, HIV status's association with the risks of past-year alcohol use (AOR = 2.00, 95% CI = 1.09-3.69), past-year cocaine use (AOR = 2.40, 95% CI = 1.06-5.39), and past-month cocaine use (AOR = 3.69, 95% CI = 1.36-10.02) also differed significantly. It is well-established that individuals with HIV face an elevated risk of substance use. Our study added valuable insights by highlighting that this phenomenon is particularly more significant among Black and Hispanic adults for several substances when compared to White adults. Implications for practice are discussed.

Communicable Disease Screening and Human Immunodeficiency Virus Prevention in the Emergency Department

Emergency departments (ED) provide care to populations with high rates of communicable diseases, like HIV, hepatitis C virus, and syphilis. For many patients, the ED is their sole entry point into the healthcare system and they do not routinely access screening and prevention services elsewhere. As such, the ED can serve an important public health role through communicable disease identification, treatment, and prevention. In this article, we examine national recommendations, peer-reviewed literature, and expert consensus to provide cutting edge strategies for implementing communicable infectious disease screening and prevention programs into routine ED care.
