The Effect of Navigation on Linkage to a PrEP Provider Among PrEP-Eligible Men who have Sex with Men in a U.S. Demonstration Project

Provider Perspectives on Multi-level Barriers and Facilitators to PrEP Access Among Latinx Sexual and Gender Minorities

Although pre-exposure prophylaxis (PrEP) is a highly effective HIV prevention intervention, inequities in access remain among Latinx sexual and gender minorities (LSGM). There is also a gap in the PrEP literature regarding providers' perspective on access inequities. This qualitative case study sought to explore barriers and facilitators to PrEP engagement in a community-based integrated health center primarily serving Latinx populations in Northern California. We conducted in-depth, semi-structured interviews with providers (9/15) involved in PrEP services and engaged in a constructivist grounded theory analysis consisting of memoing, coding, and identifying salient themes. Three participants worked as medical providers, three as outreach staff, and one each in planning, education, and research. The analysis surfaced four themes: geopolitical differences, culture as barrier, clinic as context, and patient strengths and needs. Participants referenced a lack of resources to promote PrEP, as well as the difficulties of working within an institution that still struggles with cultural and organizational mores that deprioritize sexual health. Another barrier is related to sexual health being positioned outside of patients' immediate needs owing to structural barriers, including poverty, documentation status, and education. Participants, however, observed that peer-based models, which emboldened their decision-making processes, were conducive to better access to PrEP, as well as allowing them to build stronger community ties. These data underscore the need for interventions to help reduce sexual stigma, promote peer support, and ameliorate structural barriers to sexual healthcare among LSGM.

Multilevel Intervention to Support Tailored and Responsive HIV Pre-Exposure Prophylaxis Care in Rural North Carolina: Protocol for a Randomized Controlled Trial

BACKGROUND

While access to pre-exposure prophylaxis (PrEP) is an important tool for reducing HIV incidence in the United States, disparities in uptake by race, sex, socioeconomic status, and geography persist. In 2018, the US South accounted for more than half of all new HIV diagnoses but only one-third of PrEP users. PrEP use in North Carolina (NC) similarly lags, with uptake being the lowest among young, sexual and gender minority populations, who account for nearly two-thirds of the state's incident infections. The PrEP-to-need ratio, a metric of PrEP equity that measures PrEP uptake relative to new HIV diagnoses, highlights disparities in PrEP uptake among specific demographic groups such as women and Black, Hispanic, and Southern people, indicating that these groups are underserved relative to their epidemic need. Despite behavioral risk overlap of incident sexually transmitted infections (STIs) and HIV, in NC, PrEP is only offered at a few primarily urban health department-affiliated STI clinics. The lack of robust health care infrastructure in these areas presents challenges for HIV prevention services.

OBJECTIVE

This protocol describes a randomized controlled trial of a multilevel PrEP intervention recruiting from rural and periurban STI clinics.

METHODS

This trial aims to enroll up to 336 participants and randomly assign them 1:1 to either the intervention or control group. The intervention consists of access to a digital health app, linkage to a remote PrEP navigator, and the option of referral to telehealth-based PrEP services. Persons randomly assigned to the control condition will receive an enhanced standard of care, including access to a limited version of the digital health app. All participants will be followed up on quarterly for at least 3 months. The primary outcome is the initiation of PrEP within 3 months of an index STI clinic visit; secondary outcomes evaluate PrEP care engagement and adherence, incident HIV and bacterial STI infections, PrEP stigma, and cost-effectiveness. Binary outcome analyses will estimate the proportion of participants achieving an event (eg, PrEP uptake) in each arm and a probability difference and the corresponding 95% CI to compare the intervention versus control arm at each time point. Continuous end points will use nonparametric Wilcoxon rank sum tests comparing the intervention and control groups.

RESULTS

Enrollment opened on August 31, 2023, at 15 health departments in NC and subsequently expanded to 21 facilities in 20 counties by July 2024. Completion of the enrollment and data collection phases is expected by May 2025. Results will be published thereafter.

CONCLUSIONS

This study directly addresses multiple barriers to PrEP use in rural and periurban areas of the Southeastern United States and can inform policy and programming that seek to expand PrEP access and promote use in underserved communities.

Strengthening PrEP services at community-based organizations for Latinx men who have sex with men: an implementation science approach

BACKGROUND

In Miami-Dade County Florida (Miami), the rate of newly diagnosed HIV per 100,000 population is four times the national rate with a large majority of transmission due to male-to-male sex. Latinx men are prescribed HIV preventative medication (PrEP) at a lower rate than White individuals; as such, efforts are being made by community health organizations to engage Latinx men who have sex with men (LMSM) in PrEP promotion programs. The objective of this study is to characterize the features, strengths, and weaknesses of the implementation of a PrEP promotion program (DiversiPrEP) at three community based organization (CBO) locations across Miami-Dade and Broward Counties.

METHODS

All 30 staff members were invited via e-mail to participate; 11 staff participated in semi-structured interviews were conducted by two authors to assess implementation of the DiversiPrEP program with questions mapped to the Consolidated Framework for Implementation Research (CFIR). We used directed content analysis to analyze qualitative data.

RESULTS

All staff members self-identified as male and 82% (9 of the 11) identified as Hispanic/Latino. Facilitators to providing PrEP services included: 1) individualized counseling for the PrEP process; 2) providing inviting community-focused spaces with staff who reflect the demographics of the priority population; and 3) hiring non-medical staff that bridge the gap as a translator of both medical and administrative issues. Negative influences on implementation included: 1) federal funding restrictions on lab and testing costs that hinder the ability of the CBO to provide no-cost testing to clients; and 2) finding ways to advertise services to LMSM that may not already be familiar with the CBO.

CONCLUSIONS

CBO administrative staff provide actionable policy and implementation recommendations for offering culturally tailored PrEP services in other LMSM communities. CBO can reduce PrEP service barriers by acting as intermediaries for navigation of the healthcare system and deferring costs to the clients through federal and state funding programs.

PrEP facilitators and barriers in substance use bridge clinics for women who engage in sex work and who use drugs

BACKGROUND

Women who engage in sex work and use drugs (WSWUD) experience disproportionate HIV risks. Substance use treatment bridge clinics offer an opportunity to increase HIV pre-exposure prophylaxis (PrEP) delivery to WSWUD, but research on best practices is lacking. Therefore, we explored facilitators and barriers to PrEP across the PrEP care continuum in these settings.

METHODS

Bridge clinic and affiliated harm reduction health service providers and WSWUD from Boston were recruited using passive and active outreach between December 2021 and August 2022. Participants were invited to take part in semi-structured phone or in-person interviews to explore HIV prevention and PrEP care experiences overall and within bridge clinic settings. Deductive codes were developed based on HIV risk environment frameworks and the Information-Motivation-Behavioral Skills model and inductive codes were added based on transcript review. Grounded content analysis was used to generate themes organized around the PrEP care continuum.

RESULTS

The sample included 14 providers and 25 WSWUD. Most WSWUD were aware of PrEP and more than half had initiated PrEP at some point. However, most who initiated PrEP did not report success with daily oral adherence. Providers and WSWUD described facilitators and barriers to PrEP across the steps of the care continuum: Awareness, uptake, adherence, and retention. Facilitators for WSWUD included non-stigmatizing communication with providers, rapid wraparound substance use treatment and HIV services, having a PrEP routine, and service structures to support PrEP adherence. Barriers included low HIV risk perceptions and competing drug use and survival priorities. Provider facilitators included clinical note templates prompting HIV risk assessments and training. Barriers included discomfort discussing sex work risks, competing clinical priorities, and a lack of PrEP adherence infrastructure.

CONCLUSION

WSWUD and bridge clinic providers favored integrated HIV prevention and substance use services in harm reduction and bridge clinic settings. Harm reduction and bridge clinic programs played a key role in HIV prevention and PrEP education for WSWUD. Effective behavioral and structural interventions are still needed to improve PrEP adherence for WSWUD.

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

PURPOSE OF REVIEW

Despite highly effective biomedical HIV pre-exposure prophylaxis (PrEP) options, suboptimal PrEP uptake impedes progress towards ending the epidemic in the United States of America (USA). Implementation science bridges what we know works in controlled clinical trial settings to the context and environment in which efficacious tools are intended to be deployed. In this review, we focus on strategies that target PrEP use barriers at the system or structural level, exploring the implications and opportunities in the context of the fragmented USA healthcare system.

RECENT FINDINGS

Task shifting could increase PrEP prescribers, but effectiveness evidence is scarce in the USA, and generally focused in urban settings. Integration of PrEP within existing healthcare infrastructure concentrates related resources, but demonstration projects rarely present the resource implications of redirecting staff. Changing the site of service via expanded telehealth could improve access to more rural populations, though internet connectivity, technology access, and challenges associated with determining biomedical eligibility remain logistical barriers for some of the highest burden communities in the USA. Finally, a tailored care navigation and coordination approach has emerged as a highly effective component of PrEP service provision, attempting to directly modify the system-level determinants of PrEP use experienced by the individual. We highlight recent advances and evidence surrounding task shifting, integration, service delivery, and tailoring. With the exception of tailored care navigation, evidence is mixed, and the downstream impact and sustainability of task shifting and care integration require further attention. To maximize PrEP outcomes, research will need to continue to examine the interplay between individuals, clinics, and the healthcare system and associated policies within which they operate.

HIV Prevention Services for Hispanic/Latino Persons in THRIVE, 2015-2020

INTRODUCTION

Hispanic/Latino men who have sex with men (MSM) and transgender women (TGW) are disproportionately affected by HIV in the U.S. This study evaluated HIV prevention services and outcomes among Hispanic/Latino MSM and TGW in the Targeted Highly Effective Interventions to Reduce the HIV Epidemic (THRIVE) demonstration project and consider lessons learned.

METHODS

The authors described the THRIVE demonstration project services provided to Hispanic/Latino MSM and TGW in 7 U.S. jurisdictions from 2015 to 2020. HIV prevention service outcomes were compared between 1 site with (2,147 total participants) and 6 sites without (1,129 total participants) Hispanic/Latino-oriented pre-exposure prophylaxis clinical services, and Poisson regression was used to estimate the adjusted RR between sites and pre-exposure prophylaxis outcomes. Analyses were conducted from 2021 to 2022.

RESULTS

The THRIVE demonstration project served 2,898 and 378 Hispanic/Latino MSM and TGW, respectively, with 2,519 MSM (87%) and 320 TGW (85%) receiving ≥1 HIV screening test. Among 2,002 MSM and 178 TGW eligible for pre-exposure prophylaxis, 1,011 (50%) MSM and 98 (55%) TGW received pre-exposure prophylaxis prescriptions, respectively. MSM and TGW were each 2.0 times more likely to be linked to pre-exposure prophylaxis (95% CI=1.4, 2.9 and 95% CI=1.2, 3.6, respectively) and 1.6 and 2.1 times more likely to be prescribed pre-exposure prophylaxis (95% CI=1.1, 2.2 and 95% CI=1.1, 4.1), respectively, at the site providing Hispanic/Latino-oriented pre-exposure prophylaxis clinical services than at other sites and adjusted for age group.

CONCLUSIONS

The THRIVE demonstration project delivered comprehensive HIV prevention services to Hispanic/Latino MSM and TGW. Hispanic/Latino-oriented clinical settings may improve HIV prevention service delivery to persons in Hispanic/Latino communities.

Progress Toward Equitable Mpox Vaccination Coverage: A Shortfall Analysis - United States, May 2022-April 2023

More than 30,000 monkeypox (mpox) cases were reported in the United States during the 2022 multinational outbreak; cases disproportionately affected gay, bisexual, and other men who have sex with men (MSM). Substantial racial and ethnic disparities in incidence were also reported (1). The national mpox vaccination strategy* emphasizes that efforts to administer the JYNNEOS mpox vaccine should be focused among the populations at elevated risk for exposure to mpox (2). During May 2022-April 2023, a total of 748,329 first JYNNEOS vaccine doses (of the two recommended) were administered in the United States.^† During the initial months of the outbreak, lower vaccination coverage rates among racial and ethnic minority groups were reported (1,3); however, after implementation of initiatives developed to expand access to mpox vaccination,^§ coverage among racial and ethnic minority groups increased (1,4). A shortfall analysis was conducted to examine whether the increase in mpox vaccination coverage was equitable across all racial and ethnic groups (5). Shortfall was defined as the percentage of the vaccine-eligible population that did not receive the vaccine (i.e., 100% minus the percentage of the eligible population that did receive a first dose). Monthly mpox vaccination shortfalls were calculated and were stratified by race and ethnicity; monthly percent reductions in shortfall were also calculated compared with the preceding month's shortfall (6). The mpox vaccination shortfall decreased among all racial and ethnic groups during May 2022-April 2023; however, based on analysis of vaccine administration data with race and ethnicity reported, 66.0% of vaccine-eligible persons remained unvaccinated at the end of this period. The shortfall was largest among non-Hispanic Black or African American (Black) (77.9%) and non-Hispanic American Indian or Alaska Native (AI/AN) (74.5%) persons, followed by non-Hispanic White (White) (66.6%) and Hispanic or Latino (Hispanic) (63.0%) persons, and was lowest among non-Hispanic Asian (Asian) (38.5%) and non-Hispanic Native Hawaiian and other Pacific Islander (NH/OPI) (43.7%) persons. The largest percentage decreases in the shortfall were achieved during August (17.7%) and September (8.5%). However, during these months, smaller percentage decreases were achieved among Black persons (12.2% and 4.9%, respectively), highlighting the need for a focus on equity for the entirety of a public health response. Achieving equitable progress in JYNNEOS vaccination coverage will require substantial decreases in shortfalls among Black and AI/AN persons.

Achieving the "Ending the HIV Epidemic in the U.S." incidence reduction goals among at-risk populations in the South

INTRODUCTION

Antiretroviral medication coverage remains sub-optimal in much of the United States, particularly the Sothern region, and Non-Hispanic Black or African American persons (NHB) continue to be disproportionately impacted by the HIV epidemic. The "Ending the HIV Epidemic in the U.S." (EHE) initiative seeks to reduce HIV incidence nationally by focusing resources towards the most highly impacted localities and populations. This study evaluates the impact of hypothetical improvements in ART and PrEP coverage to estimate the levels of coverage needed to achieve EHE goals in the South.

METHODS

We developed a stochastic, agent-based network model of 500,000 individuals to simulate the HIV epidemic and hypothetical improvements in ART and PrEP coverage.

RESULTS

New infections declined by 78.6% at 90%/40% ART/PrEP and 94.3% at 100%/50% ART/PrEP. Declines in annual incidence rates surpassed 75% by 2025 with 90%/40% ART/PrEP and 90% by 2030 with 100%/50% ART/PrEP coverage. Increased ART coverage among NHB MSM was associated with a linear decline in incidence among all MSM. Declines in incidence among Hispanic/Latino and White/Other MSM were similar regardless of which MSM race group increased their ART coverage, while the benefit to NHB MSM was greatest when their own ART coverage increased. The incidence rate among NHB women declined by over a third when either NHB heterosexual men or NHB MSM increased their ART use respectively. Increased use of PrEP was associated with a decline in incidence for the groups using PrEP. MSM experienced the largest absolute declines in incidence with increasing PrEP coverage, followed by NHB women.

CONCLUSIONS

Our analysis indicates that it is possible to reach EHE goals. The largest reductions in HIV incidence can be achieved by increasing ART coverage among MSM and all race groups benefit regardless of differences in ART initiation by race. Improving ART coverage to > 90% should be prioritized with a particular emphasis on reaching NHB MSM. Such a focus will reduce the largest number of incident cases, reduce racial HIV incidence disparities among both MSM and women, and reduce racial health disparities among persons with HIV. NHB women should also be prioritized for PrEP outreach.
