Improving PrEP Implementation Through Multilevel Interventions: A Synthesis of the Literature

Implementation Facilitators and Barriers for Primary Care Providers Prescribing Daily Oral PrEP to Adolescents in the United States

Primary care providers (PCPs) are critical in prescribing human immunodeficiency virus (HIV) pre-exposure prophylaxis (PrEP) to adolescents at risk of HIV. More research is needed to identify facilitators and barriers PCPs encounter in prescribing PrEP to eligible adolescents post-Food and Drug Administration (FDA) approval. This online cross-sectional survey examined the PrEP implementation facilitators and barriers among a national sample of PCPs in the United States. PCPs (n = 502) specializing in family medicine or pediatrics were recruited from a Qualtrics panel from July 15 to August 9, 2022. We analyzed the collected data using content analysis and applied the Expert Recommendations for Implementing Change (ERIC) to codebook creation and data analysis. We conducted a Fisher's exact chi-square test of independence to compare facilitator and barrier prevalence differences between participants who had and had not prescribed PrEP to an adolescent patient. Results demonstrate that (1) distributing prescriber-focused educational materials, (2) involving parents, (3) changing liability laws, (4) enhancing adolescent PrEP uptake and adherence, (5) changing clinical resources, and (6) using mass/social media to change community norms might be strategies that influence PCPs prescribing PrEP to eligible adolescent patients. Results from this study could facilitate the planning of hybrid implementation-effectiveness trials designed to determine the acceptability, feasibility, and effectiveness of implementation strategies in improving the practices of PCPs prescribing PrEP to at-risk adolescents.

Improving HIV pre-exposure prophylaxis (PrEP) uptake and initiation: process evaluation and recommendation development from a national PrEP program<a href="#FN1">†</a>

BACKGROUND

HIV pre-exposure prophylaxis (PrEP) is key to HIV transmission elimination but implementation is challenging and under-researched. We undertook a process evaluation of the first 2years of a national PrEP program to explore barriers and facilitators to implementation and to develop recommendations to improve implementation, focusing on PrEP uptake and initiation.

METHODS

Stage 1 involved semi-structured telephone interviews and focus groups (September 2018-July 2019) with geographically and demographically diverse patients seeking/using/declining/stopping PrEP (n =39), sexual healthcare professionals (n =54), community-based organisation service users (n =9) and staff (n =15) across Scotland. We used deductive thematic analysis, to derive and then map key barriers and facilitators to priority areas that experts agreed would enhance uptake and initiation. In Stage 2, we used analytic tools from implementation science to systematically generate evidence-based, theoretically-informed recommendations to enhance uptake and initiation of PrEP.

RESULTS

Barriers and facilitators were multi-levelled and interdependent. Barriers included the rapid pace of implementation without additional resource, and a lack of familiarity with PrEP prescribing. Facilitators included opportunities for acquisition of practice-based knowledge and normalisation of initiation activities. We refined our 68 'long-list' recommendations to 41 using expert input and the APEASE (Acceptability, Practicability, Effectiveness, Affordability, Side-effects, and Equity) criteria. Examples include: provision of PrEP in diverse settings to reach all in need; co-produced, culturally sensitive training resources for healthcare professionals, with focused content on non-daily dosing; meaningful collaborative working across all stakeholders.

CONCLUSIONS

These evidence-based, theory informed recommendations provide a robust framework for optimising PrEP uptake and initiation in diverse settings to ensure PrEP reaches all who may benefit.

Associations Between Sexual History Documentation in Electronic Health Records and Referral to Pre-Exposure Prophylaxis Navigator on Prescription of Pre-Exposure Prophylaxis at a Multi-Site Federally Qualified Health Center

This cross-sectional study examined the relationships between sexual history screening (SHS) and referrals to a pre-exposure prophylaxis (PrEP) navigator (non-clinical staff member who assists patients in overcoming structural barriers to PrEP) on the proportion of days covered by PrEP for adult patients at a federally qualified health center. Patients' sociodemographics, PrEP prescriptions, referral to a PrEP navigator, and SHS data were extracted from the electronic health record (EHR). The analytic sample was 214 adult patients who were human immunodeficiency virus (HIV) negative and taking PrEP to prevent infection from January 2016 to December 2019. Mixed-effects negative binomial models were conducted accounting for clustering by patients' primary care providers. Documentation of SHS was associated with a higher proportion of days covered by PrEP (incidence rate ratio = 1.44, 95% confidence interval: 1.17-1.77). There was no significant effect of having a referral to the PrEP navigator on the proportion of days covered by PrEP, nor did having a referral to the PrEP navigator moderate the relationship between having SHS documented in the EHR and the proportion of days covered by PrEP. This study is the first to investigate the relationship between having sexual history documented in the EHR, referrals to a PrEP navigator, and their combined effect on the proportion of days covered by PrEP. Results of this study provide foundational evidence for future studies examining SHS as an opportunity to improve PrEP access and adherence and indicate the need for additional research exploring the value of PrEP navigators as an implementation strategy to overcome social and structural barriers to care.

Implementation Factors Associated With Primary Care Providers' Intention to Prescribe HIV PrEP to Adolescents in the United States

PURPOSE

In the United States, adolescents (those 13-18 years old) are a key age group of those at risk for and affected by HIV. Although HIV pre-exposure prophylaxis (PrEP), one promising HIV prevention tool, is approved for eligible adolescents to use, adolescent access to PrEP is limited by primary care providers' (PCPs) willingness to prescribe it. This study examined which Theoretical Domains Framework factors are associated with PCPs' intention to prescribe PrEP to sexually active adolescents.

METHODS

A total of 770 licensed PCPs practicing family medicine, internal medicine, or pediatrics in the United States completed an online cross-sectional questionnaire. Participants were recruited through a Qualtrics panel. We used a hierarchical regression to assess the association of demographic characteristics, sexual health care practices, and the 10 Theoretical Domains Framework factors with intention to prescribe PrEP to sexually active adolescents aged 13-18 years old.

RESULTS

Although nearly all PCPs had heard about PrEP (90.9%), 30.6% ever prescribed PrEP to an adolescent. Intention to prescribe PrEP to sexually active adolescents was associated with seven out of the 10 Theoretical Domains Framework factors: knowledge, skills, professional role, belief capacity, belief consequence, environmental resource, social influence, and emotion.

DISCUSSION

Our findings demonstrate that the Theoretical Domains Framework can be employed to understand the intrapersonal, interpersonal, and environmental factors associated with PCPs' intention to prescribe sexually active adolescents PrEP. Implementation strategies are needed to implement interventions that improve provider knowledge, attitudes, and skills related to prescribing PrEP to eligible adolescents.

Successful Integration of HIV PrEP in Primary Care and Women's Health Clinical Practice: A Model for Implementation

Ending the HIV Epidemic is contingent upon the increased utilization of pre-exposure prophylaxis (PrEP). The majority of PrEP in the United States is prescribed in specialty care settings; however, to achieve national implementation goals, it is necessary to expand PrEP services in primary care and women's health clinics. To this end, a prospective cohort study was conducted of health care providers participating in one of three rounds of a virtual program aimed at increasing the number of PrEP prescribers in primary care and women's health clinics within the NYC Health and Hospitals network, the public healthcare system of New York City. Provider prescribing behavior was compared at pre-intervention (August 2018-September 2019) and post-intervention (October 2019-February 2021). Among 104 providers, the number prescribing PrEP increased from 12 (11.5%) to 51 (49%) and the number of individual patients on PrEP increased from 19 to 128. The program utilized clinical integration models centering on existing STI management workflows and was associated with increased numbers of PrEP prescribers and volume of prescriptions in primary care and women's health clinics. The dissemination of similar programs could support national scale-up of PrEP.

Sources of Information about Pre-Exposure Prophylaxis (PrEP) and Associations with PrEP Stigma, Intentions, Provider Discussions, and Use in the United States

The amount and type of information individuals receive about HIV pre-exposure prophylaxis (PrEP) may influence PrEP uptake. We surveyed 331 HIV-negative sexual and gender minorities who have sex with men at a Midwestern Pride festival in 2018 (Mage = 32, 68% White, 87% cisgender men) to assess sources and perceived tone of PrEP information and associated outcomes. Most participants (88%) had heard about PrEP. The most common sources were the internet (70%), social media (59%), and friends (54%). Messages from health campaigns were perceived as most positive and those from religious institutions as least positive. Sources differed based on demographics. Controlling for indications for PrEP use, those who heard about PrEP from health campaigns and those who heard more positive messages reported lower levels of PrEP stigma, βs = -0.27--0.23, ps < .05. Non-users who heard about PrEP from the internet had stronger intentions to use PrEP, β = 0.28, p < .05. Those who heard about PrEP from sexual partners and health campaigns were more likely to discuss PrEP with providers, PRs = 1.60-1.80, ps < .01. Finally, those who heard about PrEP from friends and partners were more likely to use PrEP, PRs = 2.01-2.24, ps < .05. Leveraging sexual partners, social network members, and health campaigns are promising avenues to advance PrEP implementation.

Longitudinal patterns of initiation, persistence, and cycling on preexposure prophylaxis among female sex workers and adolescent girls and young women in South Africa

OBJECTIVE

Female sex workers (FSW) and adolescent girls and young women (AGYW) face a disproportionately high risk of HIV in South Africa. Oral preexposure prophylaxis (PrEP) can avert new infections, but its effectiveness is linked to consistent use. Early discontinuation of PrEP in this population is high, but less is known about longitudinal patterns of PrEP use, including patterns of re-initiation and cycling.

DESIGN

Longitudinal descriptive analysis of routine program data.

METHODS

Between 2016 and 2021, 40 681 FSW and AGYW initiated PrEP at TB HIV Care, the largest PrEP provider to this population in South Africa and were included. Using survival analyses and group-based trajectory modeling, we described patterns of initiation, discontinuation, re-initiation, and cycling.

RESULTS

Total initiations increased over the life of the program for both FSW and AGYW. About 40% of FSW [0.41, 95% confidence interval (CI) [0.40-0.42]] and AGYW (0.38, 95% CI [0.37-0.38]) remained on PrEP at one month. FSW were more likely to restart PrEP, however <10% restarted PrEP within a year of initiation. Three latent trajectory groups of PrEP use were identified for FSW (low use, early cycling, and ongoing cycling) and two for AGYW (low use and ongoing cycling). Persistence was negatively associated with initiation among AGYW, but there was no clear relationship among FSW. Those initiating later in the program and older women had a reduced risk of discontinuation.

CONCLUSIONS

Persistence on PrEP was low, but cycling on and off PrEP was common, with early missed visits and inconsistent, but ongoing use. A push to increase PrEP initiations needs to factor in readiness and persistence support, to achieve public health impact.

Geographic Disparities in Availability of Spanish-Language PrEP Services Among Latino Sexual Minority Men in South Florida

Latino sexual minority men (LSMM) experience barriers in accessing HIV pre-exposure prophylaxis (PrEP), such as lack of proximate culturally-appropriate PrEP navigation services. We examined associations between LSMM's immigration status and Spanish-language PrEP service availability. LSMM clinically indicated for PrEP were recruited from October 2018 to August 2019 in South Florida and completed an interviewer-administered questionnaire. PrEP service navigators in South Florida were identified using the CDC PrEP Directory. We constructed network service areas of 1-, 2-, and 5-miles from Spanish-speaking PrEP navigators. We used multilevel logistic regression to examine associations of individual (i.e., age, income, immigration status, network density) and zip code-level (i.e., population density, poverty, HIV risk) measures with availability of Spanish-language PrEP navigation services. A total of 131 participants clustered into 60 zip codes in South Florida. Latin American-born LSMM reported higher immigration and discrimination stress, and were 91% less likely to have PrEP navigation service availability, relative to LSMM born in the US. Zip code-level HIV incidence was associated with higher service availability within a 1-mile network of Spanish-speaking PrEP navigators. Spanish-language PrEP navigation services were available in high-HIV incidence zip codes; however, Latin American-born LSMM experienced reduced availability. Immigration and discrimination stress may explain lack of availability.

Development and Validation of the Youth Pre-Exposure Prophylaxis (PrEP) Stigma Scale

To date, there are no established scales to assess PrEP stigma among youth. We validated the Youth PrEP Stigma Scale within the Adolescent Trials Network P3 study (2019-2021). Data from sexual and gender minority youth (16-24 years) who were prescribed PrEP across nine domestic sites were evaluated (N = 235). Descriptive statistics, exploratory factor analysis, and correlation coefficients are reported. Results yielded a three-factor solution (PrEP Disapproval by Others, Enacted PrEP Stigma, and PrEP User Stereotypes) with strong factor loadings and Cronbach's alphas ranging from 0.83 to 0.90, suggesting excellent internal consistency. Correlations between this Scale, anticipated HIV stigma, perceived HIV risk, and disclosure of sexual identity were significant, indicating potential for robust application. Given the persistence of HIV infections among youth, stigma as a barrier to prevention, and expansion of PrEP modalities, the Youth PrEP Stigma Scale could enhance intervention and mechanistic research among youth at elevated risk for HIV acquisition.

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

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

Initiation of HIV pre-exposure prophylaxis among youth in the United States, 2015-2018

Adolescents and young adults ("youth") account for one-fifth of new HIV diagnoses in the U.S. HIV pre-exposure prophylaxis (PrEP), which became FDA approved in adolescents in May 2018, is highly effective at preventing HIV infection though there are limited data for PrEP initiation in youth. We aimed to quantify PrEP initiation and identify factors associated with PrEP initiation among youth at risk for HIV. We conducted a retrospective cohort study of youth aged 13-26 years who had an indication for PrEP between 1 January 2015, and 31 December 2018. We used data on commercially insured US individuals from the IBM MarketScan Commercial Database. We compared factors among youth who did and did not receive PrEP. We developed a multivariable logistic regression model to identify the association of all study covariates with receipt of PrEP. Among potentially PrEP eligible youth, only 2171 (1.6%) received a PrEP prescription in the year following their PrEP eligible claim. In multivariable models, youth who received PrEP were more likely to be older (adjusted odd ratio [aOR] for 18-20 year olds = 5.11; 95% CI = 3.35-7.77; aOR for 21-26 year olds = 16.90; 95% CI = 11.0-24.7), male (aOR = 92.42; 95% CI = 68.24-125), have sexual activity with elevated risk (aOR = 7.47; 95% CI = 6.50-8.60), or be diagnosed with gonorrhea or syphilis than youth who did not receive PrEP. Our findings highlight an opportunity to improve HIV prevention early in the life course.

Examining the Correlation Between PrEP Use and Black:White Disparities in HIV Incidence in the Ending the HIV Epidemic Priority Jurisdictions

INTRODUCTION

HIV incidence remains high in the U.S. as do disparities in new HIV diagnosis between White and Black populations and access to preventive therapies like pre-exposure prophylaxis (PrEP). The federal Ending the HIV Epidemic (EHE) initiative was developed to prioritize resources to 50 jurisdictions with high HIV incidence.

METHODS

We conducted secondary analyses of data (2013-2019) from the CDC, Census Bureau, and AIDSVu to evaluate the correlation between PrEP use, HIV incidence, and HIV incidence disparities. We compared the PrEP-to-need ratio (PnR) with the ratio of Black and White HIV incidence rates in 46 EHE counties. Subsequent analyses were performed for the seven states that contained multiple EHE counties.

RESULTS

These 46 counties represented 25.9% of the U.S. population in 2019. HIV incidence ranged from 10.5 in Sacramento County, CA, to 59.6 in Fulton County, GA (per 100,000). HIV incidence disparity ranged from 1.5 in Orleans Parish, LA, to 12.1 in Montgomery County, MD. PnR ranged from 26.8 in New York County, NY, to 1.46 in Shelby County, TN. Change in HIV incidence disparities and percent change in PnR were not significantly correlated (ρ = 0.06, p = 0.69). Change in overall HIV incidence was significantly correlated with increase in PnR (ρ = -0.42, p = 0.004).

CONCLUSIONS

PrEP has the potential to significantly decrease HIV incidence; however, this benefit has not been conferred equally. Within EHE priority counties, we found significant HIV incidence disparities between White and Black populations. PrEP has decreased overall HIV incidence, but does not appear to have decreased HIV incidence disparity.

Missed Opportunities When We Focus only on Risk: Using the Concerns Based Conversation Starter to Identify Potential PrEP Candidates

Collection and use of self-reported HIV sexual risk-behaviors to identify pre-exposure prophylaxis (PrEP) candidates is common practice in PrEP providing and referral services. Critiques of this strategy highlight overreliance on self-report and contribution to ongoing PrEP stigma. As an alternative (or complimentary) approach, we evaluated a 5-item Concerns Based Conversation Starter (CBCS) that could be used to identify individuals who could benefit from PrEP. The CBCS was included in the 2019 cycle of the American Men's Internet Survey. Item responses were characterized overall and in relation to CDC risk-based PrEP indication and reported willingness to use PrEP. In total, 1606 HIV-negative men who have sex with men not on PrEP were evaluated. Of these, 50% were below the age of 25, 11% Black, 16% Latino, and 64% White. Across the sample, 61% (986) met risk-based criteria for PrEP indication, 80% (1278) were identified by the CBCS, and 52% (835) were flagged by both. The CBCS uniquely identified 28% (443) for follow-up PrEP discussions that would have been missed by a risk-based only approach. Only 9% (151) of the sample had risk-based indication but did not report concerns. Over half of those flagged by the CBCS expressed willingness to use PrEP. The CBCS identified more people than a risk-based indication approach, with most also reporting an interest in using PrEP. A small percentage of risk-indicated participants were 'missed' by the CBCS. As PrEP options and access points expand, implementation tools like the CBCS can facilitate more wide-scale, values-focused PrEP implementation.

A Qualitative Systematic Literature Review of the Role of U.S. Pharmacists in Prescribing Pre-Exposure Prophylaxis (PrEP)

Pre-Exposure Prophylaxis (PrEP) is an effective treatment to combat the human immunodeficiency virus (HIV) endemic, but the uptake of PrEP has been low in the United States (U.S.). While individuals may access PrEP via obtaining a prescription from their prescriber and having it dispensed by their pharmacist, less cumbersome access points may exist. This systematic literature review evaluates qualitative literature to explore the role of pharmacists, pharmacy services, and interprofessional collaborations for persons seeking PrEP in the United States. Four electronic databases (PubMed, Scopus, CINAHL, and Embase) were searched in February 2022 and yielded 3841 results. After excluding duplicates, two researchers reviewed 2461 studies. These results were screened for inclusion and exclusion criteria and yielded 71 studies for full review. Out of these 71 studies, five studies met the pre-selected inclusion criteria. Of the five studies, four were qualitative studies, and one was a mixed-methods study. The studies examined different aspects of initiating PrEP and diverse outcomes, such as screening for PrEP, barriers to access PrEP, feasibility to access PrEP, accessibility via community pharmacy to PrEP, and interdisciplinary collaboration between members of the healthcare team to expand patient access to PrEP. A gap in the qualitative literature focusing on U.S. pharmacists' roles in initiation and provision of PrEP for diverse populations may exist. While PrEP promotion and uptake are largely affected by convenience and accessibility, future interventions and strategies should include training pertaining to PrEP screening, stigma reduction, privacy considerations, and PrEP dispensing.

Intersectional Discrimination and PrEP uSe Among Young Black Sexual Minority Individuals: The Importance of Black LGBTQ Communities and Social Support

Intersectional stigma and discrimination have increasingly been recognized as impediments to the health and well-being of young Black sexual minority men (YBSMM) and transgender women (TW). However, little research has examined the relationship between intersectional discrimination and HIV pre-exposure prophylaxis (PrEP) outcomes. This study with 283 YBSMM and TW examines the relationship between intersectional discrimination and current PrEP use and likelihood of future PrEP use. Path models were used to test associations between intersectional discrimination, resilience and social support, and PrEP use and intentions. Individuals with higher levels of anticipated discrimination were less likely to be current PrEP users (OR = 0.59, p = .013), and higher levels of daily discrimination were associated with increased likelihood of using PrEP in the future (B = 0.48 (0.16), p = .002). Greater discrimination was associated with higher levels of resilience, social support, and connection to the Black LGBTQ community. Social support mediated the effect of day-to-day discrimination on likelihood of future PrEP use. Additionally, there was a significant and negative indirect effect of PrEP social concerns on current PrEP use via Black LGBTQ community connectedness. The results of this study highlight the complexity of the relationships between discrimination, resilience, and health outcomes.

Expanding PrEP Services for Men Who Have Sex With Men and Transgender Persons Through Health Department Programs: Key Processes and Outcomes From Project PrIDE, 2015-2019

OBJECTIVE

Pre-exposure prophylaxis (PrEP) Implementation, Data to Care, and Evaluation (PrIDE) was a demonstration project implemented by 12 state and local health departments during 2015-2019 to expand PrEP services for men who have sex with men (MSM) and transgender persons at risk for HIV infection. We describe findings from the cross-jurisdictional evaluation of the project.

METHODS

We analyzed work plans, annual progress reports, and aggregate quantitative program data submitted by funded health departments (n = 12) to identify key activities implemented and summarize key project outcomes.

RESULTS

PrIDE jurisdictions implemented multiple health equity-focused activities to expand PrEP services to priority populations, including building program capacity, conducting knowledge and awareness campaigns, providing PrEP support services, and addressing barriers to PrEP use. Overall, PrIDE jurisdictions identified 44 813 persons with PrEP indications. Of these, 74.8% (n = 33 500) were referred and 33.1% (n = 14 821) were linked to PrEP providers, and 25.3% (n = 11 356) were prescribed PrEP. Most persons prescribed PrEP were MSM or transgender persons (87.9%) and persons from racial and ethnic minority groups (65.6%). However, among persons with PrEP indications, non-Hispanic Black/African American persons (14.9% of 18 782) were less likely than non-Hispanic White persons (31.0% of 11 633) to be prescribed PrEP (z = -33.57; P < .001).

CONCLUSIONS

PrIDE jurisdictions successfully expanded PrEP services for MSM, transgender persons, and racial and ethnic minority groups by implementing health equity-focused activities that addressed barriers to PrEP services. However, PrEP prescription was generally low, with significant disparities by demographic characteristics. Additional targeted interventions are needed to expand PrEP services, achieve equity in PrEP use, and contribute to ending the HIV epidemic in the United States.

Barriers and Opportunities to Improve the Implementation of Patient Screening and Linkage to Pre-Exposure Prophylaxis in Primary Care

Although pre-exposure prophylaxis (PrEP) is highly effective at preventing HIV infection, only around 25% of at-risk individuals in the United States have accessed a prescription. One way to increase PrEP uptake is through the sexual health screening of patients and linkage to PrEP in primary care settings. The objective of this analysis was to assess the barriers and implementation strategies during a screening and linkage to PrEP pilot intervention. Primary care patients were screened for PrEP indication during routine primary care visits. Of the 1,225 individuals screened, 1.8% (n=22) were eligible for PrEP and from those, 77.3% (n=17) attended the specialist appointment and were prescribed PrEP. Primary care patients (n=30) and providers (n=8) then participated in semi-structured interviews assessing their experience with the pilot intervention. Using an applied thematic analytic approach, patients and providers identified barriers and related improvement strategies that could be classified into four main categories: 1) Financial Barriers: Individual- vs. Clinic-level Considerations 2) The Role of Stigma, Discomfort, and Cultural Factors 3) Logistical Hurdles and Streamlining the Intervention, and 4) The Lack of PrEP Knowledge and the Need for Education. Findings support the accepatability and feasibility of screening for PrEP in primary care along with appropriate implementation strategies. This study suggests that because of the high volume of patients seen in primary care, sexual health screenings and linkage to PrEP interventions have the potential to reduce new incident HIV infections among diverse sexual minority men.

Impact of COVID-19 on HIV Prevention Access: A Multi-platform Social Media Infodemiology Study

This study seeks to identify and characterize key barriers associated with PrEP therapy as self-reported by users on social media platforms. We used data mining and unsupervised machine learning approaches to collect and analyze COVID-19 and PrEP-related posts from three social media platforms including Twitter, Reddit, and Instagram. Predominant themes detected by unsupervised machine learning and manual annotation included users expressing uncertainty about PrEP treatment adherence due to COVID-19, challenges related to accessibility of clinics, concerns about PrEP costs and insurance coverage, perceived lower HIV risk leading to lack of adherence, and misinformation about PrEP use for COVID-19 prevention.

What do young people know about HIV? Results of a cross sectional study on 18-24-year-old students

Introduction

Increasing people's knowledge of transmission, prevention, early diagnosis, and available treatments is a key step toward HIV control; it means setting the conditions for empowerment and enabling individuals to make aware choices about the prevention strategy best suited to their needs. This study aims to identify unmet needs on HIV knowledge among freshman students.

Methods

A cross sectional study was carried out at the University of Cagliari, which is an Italian public state university. Data were collected by means of an anonymous questionnaire; the final sample included 801 students.

Results

Results offer a detailed picture of students' knowledge and perceptions of HIV. Several topics deserve to be better understood by students, but the main gaps relate to the pre-exposure prophylaxis and the decreased likelihood of sexually transmitting HIV due to early treatments. Students' vision of the quality of life of people living with HIV was negatively affected by perceiving as relevant the effects of HIV on physical health or on sexual/affective domains, while conversely, it seemed positively affected by knowing that current treatments are useful for counteracting physical symptoms and decreasing the possibility of transmitting HIV.

Conclusion

Being aware of the potential benefits of current therapies could favour a less negative view, in line with the current state of the beneficial effects of HIV treatment. Universities are a valuable setting to bridge the HIV knowledge gap and thus also contribute to tackling stigma and actively promoting HIV testing.

Health Care Providers' Views on Clinic Infrastructure and Practice Models That May Facilitate HIV Preexposure Prophylaxis (PrEP) Prescribing: A Qualitative Meta-Synthesis

HIV (human immunodeficiency virus) preexposure prophylaxis (PrEP) is an effective biomedical HIV prevention tool. Increasing PrEP use among populations disproportionately affected by HIV is one of the key efforts in the United States' Ending the HIV Epidemic (EHE) initiative and the HIV National Strategic Plan for the United States. Given that PrEP is available only through prescription, it is important to explore structural, organizational, or environmental factors that could facilitate or impede health care provider's PrEP prescribing behavior. The purpose of this systematic review (PROSPERO [CRD: 42019138889]) is to identify qualitative studies that addressed this topic and conduct meta-synthesis using the thematic synthesis method to identify major themes on the characteristics of clinic infrastructure or clinic models that providers consider as facilitators of PrEP prescribing in the United States. Eighteen citations representing 15 studies were included in this review. Five overarching themes were identified: (1) routinized HIV risk assessment; (2) interdisciplinary/coordinated PrEP teams or services; (3) clinic capacity to provide essential PrEP-related services; (4) low out-of-pocket patient costs; and (5) access to the priority populations. Some of these themes are consistent with the recommendations of CDC's PrEP clinical guidelines and the EHE initiative. More recent studies that include perspectives of diverse providers, timely analysis of these studies, and implementation research to assess strategies to address the current practice gaps are needed to further promote PrEP prescribing among providers in the United States.

Validation of HIV Pre-Exposure Prophylaxis (PrEP) Medication Scales with Youth on PrEP: PrEP Confidence Scale and PrEP Difficulties Scale

Pre-exposure prophylaxis (PrEP) is a lifesaving medical intervention that protects against human immunodeficiency virus (HIV), but to date, PrEP uptake has been limited. PrEP utilization and adherence among youth, including stigmatized and highly vulnerable young sexual and gender minorities, have been exceptionally low across all regions, leading to preventable HIV transmission. Considering the scientific value of measuring and understanding predictors or associations of PrEP adherence, our study team validated two scales: a PrEP Difficulties Scale and a PrEP Confidence Scale tested within the Adolescent Trials Network P3 study (2019-2021). Data from sexual and gender minorities who were prescribed PrEP across nine domestic sites were evaluated (N = 235). Descriptive statistics, exploratory factor analysis, and correlation coefficients are reported herein. Results for the PrEP Difficulties Scale yielded a four-factor solution (Disclosure, Health Effects, Logistics, and Cost), and results for the PrEP Confidence Scale produced a three-factor solution (Scheduling, Distraction, and Planning). Factor loadings and Cronbach's alphas suggested good internal consistency for both scales. PrEP Confidence Scale subscales were correlated with PrEP adherence, and subscales of both scales were associated with dimensions of social support and PrEP-related stigma. Given the persistence of preventable HIV infections among key populations, multi-level barriers and facilitators to medication adherence, and expansion of PrEP modalities, the PrEP Difficulties Scale and PrEP Confidence Scale have the potential to enhance intervention, exploratory, and mechanistic HIV prevention research. ClinicalTrials.gov Identifier: NCT03320512.

Individual and structural-level Correlates of Pre-exposure Prophylaxis (PrEP) lifetime and current use in a nationwide sample of young sexual and gender minorities

The objective of this analysis was to describe individual and structural-level factors associated with pre-exposure prophylaxis (PrEP) use among a sample of sexual and gender minorities (SGM) at risk for HIV recruited using limited interaction strategies. SGM (N = 3330), ages 15-34, without HIV enrolled in a nationwide limited interaction cohort study from 2017 to 2020. A baseline cross-sectional single-survey design examined individual and structural-level correlates of PrEP lifetime use and current use using logistic regression. PrEP lifetime use and current use were reported by 31.2% and 23.9%, respectively, of SGM with PrEP data (n = 3077). PrEP use outcomes (lifetime or current use) in cisgender MSM were associated with being over age 18, Black or other race, Hispanic/Latina/x/o ethnicity, being gay, being out to one's healthcare provider, having health insurance, being a college graduate, and having a greater number of PrEP peers. PrEP use outcomes (lifetime use or current use) in transgender/non-binary participants were associated with being over age 24, being Latinx, being transgender vs. non-binary, being assigned male at birth, being out to their healthcare provider, living in the western or northeastern United States, and having more peers on PrEP. More work is needed to address lower PrEP uptake in SGM under 18 and those whose sex risk may be more dynamic (e.g., non-binary, pansexual/queer, and bisexual SGM) and such strategies should consider utilizing peers to provide information and ameliorate structural barriers.

Determinants of PrEP Uptake, Intention and Awareness in the Netherlands: A Socio-Spatial Analysis

PrEP uptake in the Netherlands is growing but remains at suboptimal levels. Hence, the analysis of hurdles is paramount. Given the initial focus of PrEP provision among men-who-have-sex-with-men (MSM) via a demonstration project that was launched in June 2015, AmPrEP in Amsterdam, and pharmacies in the main urban areas (so called "Randstad", entailing Amsterdam, Utrecht, Leiden, The Hague and Rotterdam), investigating regional differences is necessary. This study seeks to unravel regional differences jointly with the psycho-social determinants of PrEP uptake. This cross-sectional study included 3232 HIV-negative MSM recruited via the Dutch subsample of the European-MSM-Internet-Survey in late 2017 (EMIS-2017), which aimed to inform interventions for MSM who are highly affected by infections with HIV and other sexually transmitted infections. Prevalence and the standardised prevalence ratio (SPR) of PrEP awareness, intention and uptake were measured on a regional level (Randstad vs. the rest of the country). Multi-level logistic modelling was conducted to identify the association of PrEP uptake with PrEP awareness and intention, socio-demographic, psycho-social determinants and random effects from regional differences. MSM from the Randstad used more PrEP (SPR = 1.4 vs. 0.7) compared to the rest of the country, but there were minor differences for awareness and intention. The regional distinction was estimated to explain 4.6% of the PrEP use variance. We observed a greater influence from PrEP intention (aOR = 4.5, 95% CI 2.0-10.1), while there was limited influence from the awareness of PrEP (aOR = 0.4, 95% CI 0.04-4.4). Lower education (aOR = 0.4, 95% CI 0.2-0.9) was negatively associated with PrEP uptake; however, no significant difference was found between middle (aOR = 1.2, 95% CI 0.7-2.0) and high education. We showed that regional differences-MSM in non-urban regions-and other psycho-social determinants account for lower PrEP uptake. Based on these findings, more fine-tuned PrEP access with a focus on non-urban regions can be implemented, and tailored campaigns increasing intention/use can be conducted among target populations.

Implementing PrEP Services in Diverse Health Care Settings

BACKGROUND

Uptake of pre-exposure prophylaxis (PrEP) in the US has been limited. Evidence for why and how PrEP has been successfully integrated into some clinical settings, but not in others is minimal. To address this gap, we conducted a qualitative study to identify contextual factors that facilitated and challenged the implementation of PrEP services.

SETTING

In partnership with the NYC Department of Health, we convened a planning committee with expertise with groups highly affected by the HIV epidemic employed in diverse health care settings, to guide the project. Representatives from programs within New York were targeted for participation initially and subsequently expanded nationally to enhance diversity in program type.

METHODS

Using an interview guide informed by the Consolidated Framework for Implementation Research, we conducted 20 interviews with participants who successfully implemented PrEP programs in different settings (eg, primary care, emergency department, sexual health clinics), using different delivery models. We used template and matrix analysis to identify and characterize contextual determinants and implementation strategies.

RESULTS

Participants frequently described determinants and strategies fluidly and conceptualized them in context-specific terms. Commonly discussed Consolidated Framework for Implementation Research constructs included implementation climate (tension for change, compatibility, relatively priority), stakeholders' knowledge (or lack thereof) and beliefs about PrEP, and costs associated with PrEP implementation.

CONCLUSION

Our work identifies patterns in PrEP program implementation, describing how organizations dealt with determinants in their own context. Our research points to the need to connect rigorous implementation research with how frontline implementers conceptualize their work to inform and improve PrEP implementation.

Determinants of Implementation for HIV Pre-exposure Prophylaxis Based on an Updated Consolidated Framework for Implementation Research: A Systematic Review

BACKGROUND

Delivery and use of HIV pre-exposure prophylaxis (PrEP) are suboptimal in the United States. Previous reviews of barriers and facilitators have not used an implementation science lens, limiting comprehensiveness and the link to implementation strategies. To summarize the state of the science, we systematically reviewed determinants of PrEP implementation using the updated Consolidated Framework for Implementation Research (CFIR 2.0).

SETTING

PrEP-eligible communities and delivery settings in the United States.

METHODS

In January 2021, we searched Ovid MEDLINE, PsycINFO, and Web of Science for peer-reviewed articles related to HIV/AIDS, interventions, implementation, and determinants or strategies. We identified 286 primary research articles published after 1999 about US-based PrEP implementation. Team members extracted discrete "mentioned" and "measured" determinants, coding each by setting, population, valence, measurement, and CFIR 2.0 construct.

RESULTS

We identified 1776 mentioned and 1952 measured determinants from 254 to 239 articles, respectively. Two-thirds of measured determinants were of PrEP use by patients as opposed to delivery by providers. Articles contained few determinants in the inner setting or process domains (ie, related to the delivery context), even among studies of specific settings. Determinants across priority populations also focused on individual patients and providers rather than structural or logistical factors.

CONCLUSION

Our findings suggest substantial knowledge in the literature about general patient-level barriers to PrEP use and thus limited need for additional universal studies. Instead, future research should prioritize identifying determinants, especially facilitators, unique to understudied populations and focus on structural and logistical features within current and promising settings (eg, pharmacies) that support integration of PrEP into clinical practice.

Strengthening HIV Prevention Services Through an Implementation Science Approach: Perspectives From the HIV Testers in Philadelphia

BACKGROUND

Strengthening HIV prevention services is a key priority of the Ending the HIV Epidemic plan. Informed by the Consolidated Framework for Implementation Research, we examined HIV testers' perceived barriers and facilitators to implementing HIV prevention services, including testers' strengths and weaknesses; enabling factors within the inner and outer settings; and willingness to adopt potential implementation strategies.

METHODS

In 2019, the Penn Center for AIDS Research (CFAR) partnered with the Philadelphia Department of Public Health (PDPH) to examine system-level challenges and opportunities experienced by PDPH-funded HIV testers (individuals conducting HIV testing) in Philadelphia. We recruited HIV testers to complete 2 web surveys (n ≈ 40 each) and in-depth interviews (n = 11).

RESULTS

Testers self-reported high HIV testing self-efficacy and competence, despite identifying gaps in their knowledge of STI testing, reporting moderate willingness to recommend pre-exposure prophylaxis, and having insufficient cultural competency when working with priority populations. Testers indicated that educational materials and policies within their agencies might require realignment to affirm sexual and gender minority clients. In qualitative interviews, testers noted challenges to implementing PDPH priorities because limited funding fueled competition between local agencies, deterred interagency partnerships, and limited their ability to serve key populations locally.

DISCUSSION

HIV testers are critical partners in addressing agency-level barriers to HIV prevention service provision through multilevel implementation strategies. In partnership with PDPH, we will create and implement a train-the-trainers program consisting of skill-building activities, technical assistance, and capacity-building for all agency personnel to address missed opportunities in HIV prevention. These activities will reinforce scalability and sustainability of PDPH-supported HIV prevention programs.

Proyecto Compadre: Using Implementation Science to Tailor Peer Navigation for Latino Men in the US-Mexico Border Region

BACKGROUND

Latino men who have sex with men (MSM) in San Diego have poor HIV testing and prevention outcomes compared with non-Latino White men. Peer navigation (PN) is a promising evidence-based intervention to reduce disparities but needs tailoring for Latino MSM.

SETTINGS

Health centers near the US-Mexico border.

METHODS

Using the Exploration, Preparation, Implementation, Sustainment Framework, we conducted mixed-methods implementation science study. In phase I, we conducted interviews with Latino men (n = 15), focus groups with staff (n = 7), and surveys with all to understand the Exploration, Preparation, Implementation, Sustainment factors associated with HIV testing and care linkage. In phase II, we conducted 31 web-based surveys with Latino men and staff to rank intervention and implementation strategies from phase I. Quantitative data were analyzed descriptively, integrated with qualitative data, and reviewed by our community-academic partnership to develop an implementation model.

RESULTS

Latino men (N = 15) were 94% Spanish speaking, 67% gay identified, 27% US born, and their suggestions were to have navigators use peer referral to address barriers such as stigma; use the Latino social network to expand reach, leverage social media for peer-led intervention, and disseminate HIV information. Staff (N = 26) were 77% Spanish speaking, 35% gay-identified, 96% trained in cultural competency, and suggested including culturally appropriate HIV educational materials in Spanish, status and identity neutral programs, administrative/supervisorial/training structure for PNs, and PN compensation and team integration. Overall, results emphasized a need for a formalized PN model centered on referrals and using existing Latino community social networks.

CONCLUSIONS

Findings can be packaged for future implementation of PN programs for Latino MSM.

Lessons Learned from an HIV Pre-Exposure Prophylaxis Coordination Program in San Francisco Primary Care Clinics

HIV pre-exposure prophylaxis (PrEP) has shown high efficacy and effectiveness for HIV prevention; however, many individuals with PrEP indications are not receiving PrEP. PrEP Coordinators work closely with patients and health care providers to increase PrEP access, and they provide unique insights into the inner workings of PrEP care and service delivery. In this study, we discuss key challenges and recommendations for improved PrEP service delivery (including training PrEP Coordinators to manage PrEP panels, making PrEP a part of routine care and optimizing electronic health records, designating a PrEP "champion" who can strengthen communication and leadership, using a proactive approach to increase PrEP retention, and training providers and PrEP Coordinators to meet youth-specific needs) from our discussions with the PrEP Coordinators who led PrEP panel management in San Francisco Department of Public Health primary care clinics.

Disparities in Sexually Transmitted Infection Testing and the Need to Strengthen Comprehensive Sexual Health Services for Trans Women

Purpose

Few studies have examined the importance of improving the sexual health delivery system beyond HIV among trans women. We assessed survey data from the National HIV Behavioral Surveillance Transgender Woman (NHBS-Trans) Study in San Francisco to characterize the utilization of sexual health services among HIV-negative trans women and to explore opportunities to improve sexual health services for trans women.

Methods

Trans women were recruited through respondent-driven sampling from July 2019 to February 2020. The analytic sample was restricted to 116 HIV-negative trans women. We identified trends in data using chi-squared tests to assess significance between sexual risk behavior and the use of preventative sexual health services and built logistic regression models to assess the relationships between sexual risk behaviors and sexually transmitted infection (STI) testing.

Results

The majority of sample was trans women of color with most identifying as Latinx (42.2%). Over half were low income (56%), and majority had been homeless in past 12 months (62.9%). The prevalence of condomless receptive anal sex was 52.6% with about two-thirds (62.1%) recently having an STI test. Participants who engaged in recent condomless receptive anal sex had more than fivefold greater odds of having a recent STI test compared to their counterparts who did not (adjusted odds ratio [aOR] 5.60, 95% confidence interval [CI] 1.83-17.11; p=0.003). We also found age- and education-related disparities in STI testing.

Conclusion

This study characterized the utilization of sexual health services among HIV-negative trans women and identified important disparities in STI testing. We discuss opportunities to strengthen sexual health care delivery systems.

Refining an Implementation Strategy to Enhance the Reach of HIV-Prevention and Behavioral Health Treatments to Latino Men Who Have Sex with Men

Background

Latino men who have sex with men (LMSM) experience HIV and behavioral health disparities. Yet, evidence-based interventions, such as pre-exposure prophylaxis (PrEP) and behavioral health treatments, have not been equitably scaled up to meet LMSM needs. To address quality of life and the public health importance of HIV prevention, implementation strategies to equitably scale up these interventions to LMSM need to be developed. This study identifies themes for developing culturally grounded implementation strategies to increase uptake of evidence-based HIV prevention and behavioral health treatments among LMSM.

Methods

Participants included 13 LMSM and 12 stakeholders in Miami, an HIV epicenter. Feedback regarding the content, design, and format of an implementation strategy to scale up HIV-prevention and behavioral health services to LMSM were collected via focus groups (N=3) and individual interviews (N=3). Themes were inductively identified across the Health Equity Implementation Framework (HEIF) domains.

Results

Analyses revealed five higher order themes regarding the design, content, and format of the implementation strategy: cultural context, relationships and networks, navigation of health information and systems, resources and models of service delivery, and motivation to engage. Themes were applicable across HEIF domains, meaning that the same theme could have implications for both the development and implementation of the implementation strategy.

Conclusions

Findings highlight the importance of addressing culturally specific factors, leveraging relational networks, facilitating navigation of health systems, tailoring to available resources, and building consumer and implementer motivation in order to refine an implementation strategy for reducing mental health burden and achieving HIV health equity among LMSM.

Intersectional Stigma and Prevention Among Gay, Bisexual, and Same Gender-Loving Men in New York City, 2020: System Dynamics Models

Objectives. To create causal loop diagrams that characterize intersectional stigma experiences among Black, gay, bisexual, same gender-loving, and other men who have sex with men and to identify intervention targets to reduce stigma and increase testing and prevention access. Methods. Between January and July 2020, we conducted focus groups and in-depth interviews with 80 expert informants in New York City, which were transcribed, coded, and analyzed. These qualitative insights were developed iteratively, visualized, and validated in a causal loop diagram (CLD) using Vensim software. Results. The CLD revealed 3 key feedback loops-medical mistrust and HIV transmission, serosorting and marginalization of Black and gay individuals, and family support and internalized homophobia-that contribute to intersectional HIV and related stigmas, homophobia, and systemic racism. On the basis of these results, we designed 2 novel intervention components to integrate into an existing community-level anti-HIV stigma and homophobia intervention. Conclusions. HIV stigma, systemic racism, and homophobia work via feedback loops to reduce access to and uptake of HIV testing, prevention, and treatment. Public Health Implications. The CLD method yielded unique insights into reciprocal feedback structures that, if broken, could interrupt stigmatization and discrimination cycles that impede testing and prevention uptake.

Implementing pre-exposure prophylaxis for HIV prevention in women: the role of the obstetrician-gynecologist

Pre-exposure prophylaxis is a powerful HIV prevention tool that can reduce the risk of acquiring HIV by >90% from unprotected sex and >70% from injection drug use. The peripartum period is a time of heightened HIV risk, which underscores the need for HIV prevention counseling and the provision of biomedical interventions in all stages of a woman's reproductive life. It is important that women receive nonjudgmental care, have access to discussions of HIV risk, and are provided with pre-exposure prophylaxis counseling from their women's health practitioners. Obstetrician-gynecologists and other women's health providers are uniquely positioned to identify women who would benefit from pre-exposure prophylaxis and provide it in trusted clinical settings.

Optimizing an mHealth Intervention to Improve Uptake and Adherence to HIV Pre-exposure Prophylaxis in Young Transgender Women: Protocol for a Multi-Phase Trial

BACKGROUND

Vulnerable adolescents and emerging adults (aged 18-29 years), particularly young transgender women, are among the fastest-growing HIV positive populations worldwide. Thailand has the highest adult HIV seroprevalence in Asia, with a rate of infection among this population of 18%. Widespread technology offers opportunities for innovative mobile health (mHealth) interventions. Pre-exposure prophylaxis (PrEP) is an efficacious HIV prevention strategy recommended for at-risk individuals. PrEP is highly effective when taken as prescribed, but uptake and adherence have been low, with high discontinuation rates among youth.

OBJECTIVE

We propose to develop and pilot a multi-component, technology-based intervention to promote PrEP usage. We will adapt an existing 2-session, technology-delivered, motivational interviewing-based intervention to focus on PrEP use in transgender women in Thailand. We call this the Motivational Enhancement System for PrEP Uptake and Adherence (MES-PrEP). We will also refine and enhance YaCool, a mobile app with integrated text messaging developed and used clinically by our Thai team. The new version of the app is called Enhanced YaCool, and it enables self-management of gender and sexual health (including PrEP). Our primary aim is to develop and assess the preliminary efficacy of this mHealth intervention.

METHODS

We will utilize a multiphase optimization strategy (MOST) to identify the most effective intervention component or combination of components to improve PrEP usage in Thai transgender women. The study includes two phases: phase I (R21) includes qualitative interviews with key stakeholders to explore barriers and facilitators of PrEP usage through thematic analysis to inform intervention adaptation. Following this, we will adapt and beta-test MES-PrEP and Enhanced YaCool for functionality and feasibility using a community advisory board of HIV-negative Thai transgender women. In phase II (R33), we will conduct a MOST design-based trial to evaluate the feasibility, acceptability, and preliminary efficacy of MES-PrEP and Enhanced YaCool. Eighty HIV-negative participants who are currently taking PrEP and 80 participants who are not will be randomized to four conditions: (1) standard PrEP counseling (the control condition); (2) MES-PrEP and standard PrEP counseling; (3) Enhanced YaCool and standard PrEP counseling; and (4) MES-PrEP, Enhanced YaCool, and standard PrEP counseling. Feasibility and acceptability of the intervention will be assessed through usage patterns and the System Usability Scale. Preliminary impact will be assessed by evaluating the proportion of participants who initiate PrEP and their level of adherence to PrEP. Assessments will be at baseline and 1, 3, 6, 9, and 12 months postintervention. Biomarkers of adherence to PrEP, HIV, and other sexually transmitted infections will be collected.

RESULTS

Upon project completion, we will have an optimized mHealth intervention to support the use of PrEP by transgender women that will be ready for testing in a larger efficacy trial.

CONCLUSIONS

Even though transgender women in Thailand face increasing risks of HIV, few interventions have targeted them. Effective developmentally and culturally tailored interventions are needed to prevent HIV transmission in this high-risk population.

Pharmacy-Based Interventions to Increase Use of HIV Pre-exposure Prophylaxis in the United States: A Scoping Review

HIV pre-exposure prophylaxis (PrEP) remains underutilized in the U.S. Since greater than 85% of PrEP prescriptions are filled at commercial pharmacies, pharmacists are uniquely positioned to increase PrEP use. This scoping review explores pharmacy-based initiatives to increase PrEP use. We searched PubMed, PsycINFO, CINAHL, and Scopus for peer-reviewed studies on pharmacist-led interventions to increase PrEP use or pharmacy-based PrEP initiatives. Forty-nine articles were included in this review. Overall, studies demonstrated that patients expressed strong support for pharmacist prescription of PrEP. Three intervention designs compared changes in PrEP initiation or knowledge pre- and post-intervention. Commentary/review studies recommended PrEP training for pharmacists, policy changes to support pharmacist screening for HIV and PrEP prescription, and telemedicine to increase prescriptions. Pharmacists could play key roles in improving PrEP use in the U.S. Studies that assess improvements in PrEP use after interventions such as PrEP prescription, PrEP-specific training, and adherence monitoring by pharmacists are needed.

Social determinants of health and HIV Pre-Exposure Prophylaxis (PrEP) interest and use among young Black and Latinx sexual minority men

Young Black and Latinx sexual minority men (YBLSMM) have low use of HIV pre-exposure prophylaxis (PrEP), despite high rates of new HIV diagnosis. While unmet social determinants of health (SDOH) have been associated with low uptake of preventive health services, this association is unknown for PrEP. To understand the relationship between SDOH and PrEP adoption in this population, we analyzed data from an online survey of HIV-negative YBLSMM aged 18-29 in New York City (n = 143). Participants completed a 17-item SDOH needs scale measuring basic, health/social-services, and economic needs. We used regression models to examine associations of unmet SDOH with outcomes of intention to use PrEP and current PrEP use. Of those not on PrEP (n = 114), 69 (61%) intended to use PrEP. More unmet SDOH needs overall were associated with intention to use PrEP (OR 1.4; 95% CI 1.1, 2.0), as were more unmet basic needs (OR 1.7; 95% CI 1.1, 2.5) and more unmet economic needs (OR 1.3; 95% CI 1.0, 1.7). Unmet SDOH needs were not associated with current PrEP use. Findings suggest that intention to use PrEP among YBLSMM is a likely marker of unmet SDOH needs, as YBLSMM with unmet needs may have limited resources to support moving from intention to actual use. Future research should evaluate programs engaging YBLSMM intending to use PrEP with interventions to screen for and address SDOH.

Applying implementation science frameworks to identify factors that influence the intention of healthcare providers to offer PrEP care and advocate for PrEP in HIV clinics in Colombia: a cross-sectional study

Background

Few studies have used implementation science frameworks to identify determinants of PrEP prescription by healthcare providers. In this work, we developed and psychometrically examined a questionnaire using the theoretical domains framework (TDF) and the consolidated framework for implementation research (CFIR). We used this questionnaire to investigate what factors influence the intention of healthcare providers to offer PrEP care and advocate for PrEP.

Methods

We conducted a cross-sectional study in 16 HIV healthcare organizations in Colombia. A 98-item questionnaire was administered online to 129 healthcare professionals. One hundred had complete data for this analysis. We used exploratory factor analysis to assess the psychometric properties of both frameworks, and multinomial regression analysis to evaluate the associations of the frameworks’ domains with two outcomes: (1) intention to offer PrEP care and (2) intention to advocate for PrEP impmentation.

Results

We found support for nine indices with good internal consistency, reflecting PrEP characteristics, attitudes towards population needs, concerns about the use of PrEP, concerns about the role of the healthcare systems, knowledge, beliefs about capabilities, professional role, social influence, and beliefs about consequences. Notably, only 57% of the participants were likely to have a plan to care for people in PrEP and 66.7% were likely to advocate for PrEP. The perception of the need for PrEP in populations, the value of PrEP as a practice, the influence of colleagues, and seeing PrEP care as a priority was related to being less likely to be unwilling to provide or advocate for PrEP care.

Conclusion

Our findings suggested the importance of multilevel strategies to increase the provision of PrEP care by healthcare providers including adquisition of new skills, training of PrEP champions, and strength the capacity of the health system.

Persistence on oral pre-exposure prophylaxis (PrEP) among female sex workers in eThekwini, South Africa, 2016–2020

Background

Despite the established efficacy of PrEP to prevent HIV and the advantages of a user-controlled method, PrEP uptake and persistence by women in both trials and demonstration projects has been suboptimal. We utilized real-world data from an HIV service provider to describe persistence on oral PrEP among female sex workers (FSW) in eThekwini, South Africa.

Methods

We examined time from PrEP initiation to discontinuation among all FSW initiating PrEP at TB HIV Care in eThekwini between 2016–2020. We used a discrete time-to-event data setup and stacked cumulative incidence function plots, displaying the competing risks of 1) not returning for PrEP, 2) client discontinuation, and 3) provider discontinuation. We calculated hazard ratios using complementary log-log regression and sub-hazard ratios using competing risks regression.

Results

The number of initiations increased each year from 155 (9.3%, n = 155/1659) in 2016 to 1224 (27.5%, n = 1224/4446) in 2020. Persistence 1-month after initiation was 53% (95% CI: 51%-55%). Younger women were more likely to discontinue PrEP by not returning compared with those 25 years and older. Risk of discontinuation through non-return declined for those initiating in later years. Despite the COVID-19 pandemic, a greater number of initiations and sustained persistence were observed in 2020.

Conclusions

Low levels of PrEP persistence were observed, consistent with data among underserved women elsewhere. Encouragingly, the proportion of women persisting increased over time, even as the number of women newly initiating PrEP and staff workload increased. Further research is needed to understand which implementation strategies the program may have enacted to facilitate these improvements and what further changes may be necessary.

A qualitative exploration to understand barriers and facilitators to daily oral PrEP uptake and sustained adherence among HIV-negative women planning for or with pregnancy in rural Southwestern Uganda

INTRODUCTION

Antiretroviral pre-exposure prophylaxis (PrEP) may reduce periconception and pregnancy HIV incidence among women in settings, where gender power imbalances limit HIV testing, engagement in care and HIV viral suppression. We conducted qualitative interviews to understand factors influencing periconception and pregnancy PrEP uptake and use in a cohort of women (Trial registration: NCT03832530) offered safer conception counselling in rural Southwestern Uganda, where PrEP uptake was high.

METHODS

Between March 2018 and January 2019, in-depth interviews informed by conceptual frameworks for periconception risk reduction and PrEP adherence were conducted with 37 women including those with ≥80% and <80% adherence to PrEP doses measured by electronic pill cap, those who never initiated PrEP, and seven of their male partners. Content and dyadic analyses were conducted to identify emergent challenges and facilitators of PrEP use within individual and couple narratives.

RESULTS

The median age for women was 33 years (IQR 28, 35), 97% felt likely to acquire HIV and 89% initiated PrEP. Individual-level barriers included unwillingness to take daily pills while healthy, side effects and alcohol use. Women overcame these barriers through personal desires to have control over their HIV serostatus, produce HIV-negative children and prevent HIV transmission within partnerships. Couple-level barriers included nondisclosure, mistrust and gender-based violence; facilitators included shared goals and perceived HIV protection, which improved communication, sexual intimacy and emotional support within partnerships through a self-controlled method. Community-level barriers included multi-level stigma related to HIV, ARVs/PrEP and serodifference; facilitators included active peer, family or healthcare provider support as women aspired to safely meet socio-cultural expectations to conceive and preserve serodifferent relationships. Confidence in PrEP effectiveness was promoted by positive peer experiences with PrEP and ongoing HIV testing.

CONCLUSIONS

Multi-level forms of HIV-, serodifference- and disclosure-related stigma, side effects, pill burden, alcohol use, relationship dynamics, social, professional and partnership support towards adaptation and HIV risk reduction influence PrEP uptake and adherence among HIV-negative women with plans for pregnancy in rural Southwestern Uganda. Confidence in PrEP, individually controlled HIV prevention and improved partnership communication and intimacy promoted PrEP adherence. Supporting individuals to overcome context-specific barriers to PrEP use may be an important approach to improving uptake and prolonged use.

HIV PrEP services for MSM in China: a mixed-methods study

Pre-exposure prophylaxis (PrEP) is a promising HIV prevention method. However, the rollout of PrEP among men who have sex with men (MSM) is facing challenges. This study sought to understand PrEP acceptability and service use challenges among MSM in China. The study was conducted in 2018 in Guangdong Province using a mixed-methods approach. Among 489 HIV-negative MSM who completed an online survey, 374 (76.5%) had heard of PrEP before. The most common PrEP information sources were internet/social media (32.1%) and community-based organizations (30.4%). Two-thirds (n=328) of the MSM would accept PrEP even the protective efficacy is less than 100%, 60.1% (n=294) expressed willingness to use PrEP once it is approved in China, and 59.3% (n=290) were willing to pay out of pocket. Employment, disclosure of MSM status, and mental health issues were associated with PrEP acceptability. In-depth interviews with 30 MSM revealed that high cost, low accessibility, and stigma in clinic settings were barriers to PrEP using. Primary care-based PrEP services were acceptable, but patients' confidentiality was a concern. PrEP promotion efforts should address social and mental health challenges among MSM and mobilize primary care systems and community-based organizations to achieve the best result.

Defining the Pre-exposure Prophylaxis Care Continuum Among Recently Incarcerated Men at High Risk for HIV Infection: Protocol for a Prospective Cohort Study

BACKGROUND

HIV disproportionately impacts criminal justice-involved individuals, including men who experience incarceration. Men make up the vast majority of those experiencing incarceration as well as those newly diagnosed with HIV infection. Pre-exposure prophylaxis (PrEP) is a highly effective biomedical intervention that significantly reduces the risk of HIV acquisition. However, implementation in criminal justice systems is limited. Little is known about effective PrEP implementation and use in this unique public health context.

OBJECTIVE

The aim of this study is to characterize the experience of implementing PrEP clinical care in a criminal justice setting for men vulnerable to HIV acquisition.

METHODS

This article describes a PrEP care continuum for men experiencing incarceration who are at increased risk of HIV acquisition, which can help conceptualize approaches to evaluating PrEP implementation.

RESULTS

The outlined study will enroll 100 men experiencing incarceration at high risk for HIV acquisition prior to release into the community. The goal is to initiate PrEP prior to release and link individuals to PrEP providers in the community, capturing barriers and facilitators to PrEP use during this uniquely vulnerable time period for HIV acquisition.

CONCLUSIONS

Based on the proposed care continuum and what is known about HIV risk and prevention efforts in the criminal justice context, we outline key future research efforts to better understand effective approaches to preventing HIV infection among this vulnerable population. The described approach presents a powerful public health opportunity to help end the HIV epidemic.

Implementation and evaluation of patient navigation in Chicago: Insights on addressing the social determinants of health and integrating HIV prevention and care services

Patient navigation is a primary element in linkage to HIV pre-exposure prophylaxis (PrEP) care and linkage to or re-engagement in HIV care, depending on the HIV status of the individual. However, there is a dearth of literature describing navigation services in these areas. In the context of Chicago Project PrIDE, this project conducted process and implementation evaluations with eight agencies leading demonstration projects to address these gaps. The evaluation team conducted semi-structured, individual interviews with agency staff (N = 20) assessing navigation implementation and fit, as well as project successes and challenges. Additionally, agency staff collected patient surveys (N = 300) assessing services provided, service quality, and satisfaction. The interview transcripts were coded and analyzed thematically and descriptive analyses were performed on the survey data. Analyses indicated that screening for social determinants of health, providing healthcare engagement guidance, and providing service referrals were frequently cited navigation activities. Most staff members indicated that navigation fits well within their agencies, and that limited staff and clinic capacity were often barriers to navigation. Patient navigation to support engagement in HIV prevention and care services is critical due to the extensive support provided by navigators to address social determinants of health impacting HIV disparity populations.

Game Plan-a Brief Web-Based Intervention to Improve Uptake and Use of HIV Pre-exposure Prophylaxis (PrEP) and Reduce Alcohol Use Among Gay and Bisexual Men: Content Analysis

Background

HIV pre-exposure prophylaxis (PrEP) has considerable potential for reducing incidence among high-risk groups, such as gay, bisexual, and other men who have sex with men (GBM). However, PrEP’s effectiveness is closely linked with consistent use, and a variety of individual-level barriers, including alcohol use, could impede optimal uptake and use. Web-based interventions can encourage medication adherence, HIV prevention behaviors, and responsible drinking and may help support PrEP care, particularly in resource-limited settings.

Objective

We previously developed a web application called Game Plan that was designed to encourage heavy drinking GBM to use HIV prevention methods and reduce their alcohol use and was inspired by brief motivational interventions. This paper aims to describe the web-based content we designed for integration into Game Plan to help encourage PrEP uptake and consistent use among GBM. In this paper, we also aim to describe this content and its rationale.

Similar to the original site, these components were developed iteratively, guided by a thorough user-centered design process involving consultation with subject-matter experts, usability interviews and surveys, and user experience surveys.

Results

In addition to Game Plan’s pre-existing content, the additional PrEP components provide specific, personal, and digestible feedback to users about their level of risk for HIV without PrEP and illustrate how much consistent PrEP use could reduce it; personal feedback about their risk for common sexually transmitted infections to address low-risk perceptions; content challenging common beliefs and misconceptions about PrEP to reduce stigma; content confronting familiar PrEP and alcohol beliefs; and a change planning module that allows users to select specific goals for starting and strategies for consistent PrEP use. Users can opt into a weekly 2-way SMS text messaging program that provides similar feedback over a 12-week period after using Game Plan and follows up on the goals they set.

Conclusions

Research preliminarily testing the efficacy of these components in improving PrEP outcomes, including uptake, adherence, sexually transmitted infection rates, and alcohol use, is currently ongoing. If supported, these components could provide a scalable tool that can be used in resource-limited settings in which face-to-face intervention is difficult.

A typology of power in implementation: Building on the exploration, preparation, implementation, sustainment (EPIS) framework to advance mental health and HIV health equity

Background

Persistent inequities in HIV health are due, in part, to barriers to successful HIV-related mental health intervention implementation with marginalized groups. Implementation Science (IS) has begun to examine how the field can promote health equity. Lacking is a clear method to analyze how power is generated and distributed through practical implementation processes and how this power can dismantle and/or reproduce health inequity through intervention implementation. The aims of this paper are to (1) propose a typology of power generated through implementation processes, (2) apply this power typology to expand on the Exploration, Preparation, Implementation, Sustainment (EPIS) framework to advance HIV and mental health equity and (3) articulate questions to guide the explicit examination and distribution of power throughout implementation.

Methods

This paper draws on the work of an Intermediary Purveyor organization implementing trauma-informed care and harm reduction organizational change with HIV service organizations. The expanded framework was developed through analyzing implementation coaching field notes, grant reporting, and evaluation documents, training feedback, partner evaluation interviews, and existing implementation literature.

Results

The authors identify three types of power working through implementation; (1) discursive power is enacted through defining health-related problems to be targeted by intervention implementation, as well as through health narratives that emerge through implementation; (2) epistemic power influences whose knowledge is valued in decision-making and is recreated through knowledge generation; and (3) material power is created through resource distribution and patterns of access to health resources and acquisition of health benefits provided by the intervention. Decisions across all phases and related to all factors of EPIS influence how these forms of power striate through intervention implementation and ultimately affect health equity outcomes.

Conclusions

The authors conclude with a set of concrete questions for researchers and practitioners to interrogate power throughout the implementation process.

Plain language summary

Over the past few years, Implementation Science researchers have committed increased attention to the ways in which the field can more effectively address health inequity. Lacking is a clear method to analyze how implementation processes themselves generate power that has the potential to contribute to health inequity. In this paper, the authors describe and define three types of power that are created and distributed through intervention implementation; discursive power, epistemic power, and material power. The authors then explain how these forms of power shape factors and phases of implementation, using the well-known EPIS (exploration, preparation, implementation, sustainment) framework. The authors draw from their experience working with and Intermediary Purveyor supporting HIV service organizations implementing trauma-informed care and harm reduction organizational change projects. This paper concludes with a set of critical questions that can be used by researchers and practitioners as a concrete tool to analyze the role of power in intervention implementation processes.

What makes an optimal delivery for PrEP against HIV: A qualitative study in MSM

BACKGROUND

Pre-exposure prophylaxis (PrEP) is an effective means of HIV prevention for men who have sex with men (MSM), a key population whose engagement is crucial for achieving effective public health outcomes. An optimal service model would be important in planning the implementation of PrEP in places where such service has not been established.

METHODS

A qualitative study was conducted to delineate the attributes of an optimal PrEP service model for MSM in Hong Kong, a city where no formal PrEP programs existed. Twenty purposively sampled MSM who were enrollees of two pilot PrEP projects participated in the semi-structured interviews promoting story-telling. The coded data were thematically analyzed following Grounded Theory approach, focusing on uncovering a typology of the essential attributes of an optimal PrEP service model, and the reasons for such preferences.

RESULTS

Participating MSM were all ethnic Chinese and aged 26 to 52 years. All had received PrEP from pilot projects in conjunction with periodic screening of sexually transmitted infections (STI), HIV antibody, and plasma creatinine. Four major themes emerged as regards the attributes of a preferred PrEP service: (i) comprehensiveness of HIV/STI and safety monitoring; (ii) convenient unitary service; (iii) stigma-free PrEP access and protecting confidentiality; and (iv) affordable price. Whereas regular provision of PrEP was acceptable to MSM, unaffordability and related stigma were the anticipated challenges for potential service providers.

CONCLUSIONS

The qualitative assessment of MSM's preference for PrEP service delivery has yielded important information on the many facets of a desirable service model.

Latinx Sexual Minority Men's Access to HIV and Behavioral Health Services in South Florida During COVID-19: A Qualitative Study of Barriers, Facilitators, and Innovations

ABSTRACT

Despite the availability of HIV prevention and treatment tools, HIV disparities continue to affect Latinx sexual minority men (LSMM). Behavioral health concerns further exacerbate HIV disparities among LSMM. This study used rapid qualitative analysis to understand factors influencing LSMM's access to HIV and behavioral health services during coronavirus disease 2019 (COVID-19). Participants included LSMM with (n = 10) and without HIV (n = 10). The analysis identified 15 themes. Themes revealed that LSMM's access was disrupted by new and worsening barriers resulting from COVID-19, such as anxiety about COVID-19 exposure, confusion and disruptions to services, and new structural challenges. Other themes highlight positive changes, such as telehealth and relaxed clinic protocols, which enhanced LSMM's access to services during COVID-19. The findings suggest the need for HIV and behavioral health clinics to innovate and ensure LSMM's continued access to services during and beyond COVID-19.

Unsupervised Machine Learning to Detect and Characterize Barriers to Pre-exposure Prophylaxis Therapy: Multiplatform Social Media Study

Background

Among racial and ethnic minority groups, the risk of HIV infection is an ongoing public health challenge. Pre-exposure prophylaxis (PrEP) is highly effective for preventing HIV when taken as prescribed. However, there is a need to understand the experiences, attitudes, and barriers of PrEP for racial and ethnic minority populations and sexual minority groups.

Objective

This infodemiology study aimed to leverage big data and unsupervised machine learning to identify, characterize, and elucidate experiences and attitudes regarding perceived barriers associated with the uptake and adherence to PrEP therapy. This study also specifically examined shared experiences from racial or ethnic populations and sexual minority groups.

Methods

The study used data mining approaches to collect posts from popular social media platforms such as Twitter, YouTube, Tumblr, Instagram, and Reddit. Posts were selected by filtering for keywords associated with PrEP, HIV, and approved PrEP therapies. We analyzed data using unsupervised machine learning, followed by manual annotation using a deductive coding approach to characterize PrEP and other HIV prevention-related themes discussed by users.

Results

We collected 522,430 posts over a 60-day period, including 408,637 (78.22%) tweets, 13,768 (2.63%) YouTube comments, 8728 (1.67%) Tumblr posts, 88,177 (16.88%) Instagram posts, and 3120 (0.6%) Reddit posts. After applying unsupervised machine learning and content analysis, 785 posts were identified that specifically related to barriers to PrEP, and they were grouped into three major thematic domains: provider level (13/785, 1.7%), patient level (570/785, 72.6%), and community level (166/785, 21.1%). The main barriers identified in these categories included those associated with knowledge (lack of knowledge about PrEP), access issues (lack of insurance coverage, no prescription, and impact of COVID-19 pandemic), and adherence (subjective reasons for why users terminated PrEP or decided not to start PrEP, such as side effects, alternative HIV prevention measures, and social stigma). Among the 785 PrEP posts, we identified 320 (40.8%) posts where users self-identified as racial or ethnic minority or as a sexual minority group with their specific PrEP barriers and concerns.

Conclusions

Both objective and subjective reasons were identified as barriers reported by social media users when initiating, accessing, and adhering to PrEP. Though ample evidence supports PrEP as an effective HIV prevention strategy, user-generated posts nevertheless provide insights into what barriers are preventing people from broader adoption of PrEP, including topics that are specific to 2 different groups of sexual minority groups and racial and ethnic minority populations. Results have the potential to inform future health promotion and regulatory science approaches that can reach these HIV and AIDS communities that may benefit from PrEP.

Using an on-site modular training approach to amplify prep service delivery in public health facilities in Kenya

Delivery of oral PrEP, a potent HIV prevention intervention, has begun within public health systems in many countries in Africa. Training as many health providers as possible expeditiously is necessary to efficiently and rapidly scale up PrEP delivery among at risk populations and thereby realize the greatest impact of PrEP. We designed and implemented an innovative on-site modular training approach delivered in five two-hour modules. The modules could be covered in two consecutive days or be broken across several days enabling flexibility to accommodate health provider work schedules. We assessed knowledge gain comparing pre-and post-training test scores and determined monthly PrEP uptake for six months following the training intervention. We also evaluated the cost of this training approach and conducted key informant interviews to explore acceptability among health providers. Between January 2019 and December 2020, 2111 health providers from 104 health facilities were trained on PrEP. Of 1821 (83%) providers who completed both pre- and post-tests, 505 (28%) were nurses, 333 (18%) were HIV counsellors, 276 (15%) were clinical officers and 255 (14%) were lay providers. The mean score prior to and after training was 58% and 82% respectively (p <0.001). On average, health facilities initiated an average of 2.7 (SD 4.7) people on PrEP each month after the training, a number that did not decline over six months post-training (p = 0.62). Assuming Ministry of Health costs, the costs per provider trained was $16.27. Health providers expressed satisfaction with this training approach because it enabled many providers within a facility receive training. On-site modular training is an effective approach for improving PrEP education for health workers in public health facilities, It is also acceptable and low-cost. This method of training can be scaled up to rapidly amplify the number of health workers able to offer PrEP services.
