Delivering PrEP to adults with "low" or "no" HIV risk and youth: experiences and perspectives of PrEP providers

Patient and Provider Perceptions of Barriers and Facilitators to Pre-exposure Prophylaxis Access and Adherence in Black and Latinx Young Men Who Have Sex with Men

In the United States, the use of pre-exposure prophylaxis (PrEP) has led to a substantial decrease in HIV prevalence and incidence. However, some populations, including young men who have sex with men (YMSM) of color, continue to be disproportionately impacted, highlighting the need for tailored interventions addressing barriers to adequate PrEP access. In collaboration with partner clinics, we recruited 19 PrEP clients and 19 PrEP providers (n = 35) to participate in hour-long in-depth interviews. Although client interviews explored personal experiences with stigma, barriers, and motivators to PrEP and information preferences, provider interviews explored providers' perceived stigma in their clinic, perceived barriers and motivators to meeting clients' PrEP needs, and rapport building with clients. Most participants were affiliated with one of the southern partner clinics. Clients and providers noted similar determinants to PrEP access, uptake, and adherence. Both recognized the impact of personal barriers such as routine adjustments and perception of need, as well as institutional barriers such as transportation and financial difficulties. Clients emphasized the role of the client-provider relationship as part of contributing to willingness to disclose information such as HIV status and sexual practices. Providers noted the importance of sexual health and LGBTQ+ topics in their training. Despite limited geographical scope and the sensitive nature of HIV-related topics, this study has several implications. PrEP clinics may benefit from hiring providers who share identities and experiences with YMSM clients of color and operating with a flexible schedule. Medical provider training should include comprehensive sexual health and LGBTQ+ competencies to reduce bias in care.

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.

Knowledge, sex, and region associated with primary care providers prescribing adolescents HIV pre-exposure prophylaxis

Although HIV pre-exposure prophylaxis (PrEP) effectively and safely prevents HIV among adolescents, uptake of PrEP is low. Adolescents must have primary care providers (PCPs) prescribe them PrEP, making PCPs critical actors in PrEP delivery. However, research has primarily investigated determinants of PCPs' intention to prescribe adolescents PrEP rather than the determinants of performing the behavior itself. We examined the demographic, clinical practice, and implementation determinants of PCPs previously prescribing PrEP to adolescents. PCPs were recruited from a national Qualtrics panel of licensed medical providers in the United States from July 15-August 19, 2022. The Theoretical Domains Framework informed the implementation determinants measured. A multivariable logistic regression was used. PCPs who were more knowledgeable of the CDC guidelines (aOR 2.97, 95% CI 2.16-4.10), who were assigned male at birth (aOR 1.64, 95% CI 1.03-2.59), and who practiced in the Western region (aOR 1.85, 95% CI 1.04-3.30) had greater odds of prior prescribing adolescents PrEP. Provider-based educational interventions should be designed, implemented, and tested to encourage PCPs to prescribe PrEP to eligible adolescents.

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.

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.

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

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

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.
