HIV Post-Exposure Prophylaxis (PEP) Awareness and Non-Occupational PEP (nPEP) Prescribing History Among U.S. Healthcare Providers

Longitudinal predictors of post-exposure prophylaxis awareness among latino sexual minority men in South Florida

Biomedical tools for HIV prevention such as post-exposure prophylaxis (PEP) continue to be underutilized by subgroups experiencing significant HIV inequities. Specifically, factors associated with both PEP awareness and uptake both cross-sectionally and longitudinally are under-researched, despite PEP being a part of the United States' Plan for Ending the HIV Epidemic. The current study examined longitudinal predictors of PEP awareness among Latino sexual minority men (LSMM) living in South Florida. This current study (N = 290) employed hierarchal linear modeling across three timepoints (baseline, 4-months, 8-months) to assess within-person and between-person effects over time for several psychosocial and structural factors. Most participants (67.5%) reported little to no awareness of PEP at baseline with general PEP awareness growing slightly across the study (60.5% reporting little to no awareness of PEP at 8 months). Results of the final conditional model suggest significant within-person effects of PrEP knowledge (p = 0.02) and PrEP self-efficacy (p < 0.001), as well as a significant positive between-person effect of PrEP knowledge (p < 0.01) on PEP awareness. Between-person HIV knowledge was also a significant predictor in this model (p = 0.01). This longitudinal analysis of LSMM's PEP awareness indicates that more must be done to increase PEP awareness among this subgroup. Future studies should explore how to build on existing interventions focused on HIV and PrEP knowledge and PrEP self-efficacy to incorporate information about PEP to increase the reach of this effective biomedical HIV prevention tool.

Navigating Barriers and Opportunities: Perceptions of the Non-Occupational Post-Exposure Prophylaxis Care Continuum Among Young Sexual Minority Men, Aged 17-24, in the United States

Human immunodeficiency virus (HIV) is a public health concern among young sexual minority men (YSMM), ages 17 to 24, in the United States. Biomedical prevention methods, such as pre-exposure prophylaxis (PrEP) and non-occupational post-exposure prophylaxis (nPEP), can help reduce the risk of HIV transmission among this population. However, there is limited awareness and use of nPEP by YSMM. This study aims to explore the perceptions of YSMM regarding the nPEP care continuum, which consists of three areas of focus: awareness, uptake, and linkage to other HIV prevention services. This study draws on synchronous online focus groups with a sample of 41 YSMM in the United States. Transcripts from the focus groups were analyzed using reflexive thematic analysis. Participants reported limited nPEP awareness and prior use, a process of personal appraisal of nPEP need based on HIV risk and costs, and a preference for PrEP over PEP for long-term HIV prevention. Interventions should be tailored to increase awareness of nPEP among YSMM and reduce addressable barriers to nPEP use for YSMM, including cost and confidentiality concerns, in situations where nPEP is warranted. Finally, more research is needed on how nPEP use can act as a bridge to PrEP initiation for this population.

Expanding expedited partner therapy and HIV prophylaxis in the emergency department

PURPOSE

Sexually transmitted infections (STIs) continue to have a disproportionate impact on individuals belonging to sexual, gender, and racial minorities. Across the nation, many emergency medicine pharmacists (EMPs) possess the skills and knowledge to expand the provision of expedited partner therapy (EPT) for STIs and provide HIV prophylaxis within existing practice frameworks. This report serves as a call to action for expanded provision of EPT and HIV prophylaxis by EMPs and highlights current barriers and solutions to increase pharmacist involvement in these practice areas.

SUMMARY

Emergency medicine pharmacy practice continues to expand to allow for limited prescribing authority through collaborative practice agreements (CPAs). In recent years, CPA restrictions have been changed to facilitate treatment of more patients with less bureaucracy. This report addresses the unique challenges and opportunities for expanding EPT and HIV pre- and postexposure prophylaxis provision by pharmacists in emergency departments (EDs). Furthermore, current strategies and treatments for EPT, such as patient-delivered partner therapy and HIV prophylaxis, are discussed. Pharmacist involvement in STI treatment and HIV prevention is a key strategy to increase access to high-risk populations with high ED utilization and help close current gaps in care.

CONCLUSION

Expanding EMP provision of EPT and HIV prophylaxis may be beneficial to reducing the incidence of STIs and HIV infection in the community. CPAs offer a feasible solution to increase pharmacist involvement in the provision of these treatments. Legislative efforts to expand pharmacist scope of practice can also contribute to increasing access to EPT and HIV prophylaxis. With these efforts, EMPs can play an essential role in the fight against STIs and HIV.

The Role of Community Pharmacies in Providing Access to HIV Post-exposure Prophylaxis (PEP)

HIV affects an estimated 1.2 million individuals in the United States and is disproportionately concentrated among African Americans, Latinos, and people of multiple races. Post-exposure prophylaxis (PEP) substantially decreases HIV transmission when started within 72 h after exposure, but problems of accessibility have hindered its widespread usage in communities at risk for HIV infection. Pharmacy-initiated PEP access was first permitted in New York City in 2017, allowing pharmacists to provide a 7-day supply of PEP without a prescription for consumers at high risk for HIV infection. It was expected that the broad reach and accessibility of community pharmacies would increase timely access to PEP for all individuals, especially those who already face significant barriers to accessing the healthcare system. Since then, eleven other states have followed suit and expanded the scope of outpatient pharmacy practice in order to increase the availability of HIV PEP but prescribing laws in over 75% of the US have not been changed. Much of the existing literature on HIV prevention focuses on PrEP access barriers with limited information on PEP access in the US. In this paper, we review the current status of pharmacist-initiated PEP in the US as part of the End the HIV Epidemic (EHE) initiative.

Analysis of HIV drug prophylaxis services cascade in healthcare workers: a cross-sectional study in China

BACKGROUND

Human immunodeficiency virus (HIV) drug prophylaxis, including post-exposure prophylaxis (PEP) and pre-exposure prophylaxis (PrEP), has not yet been generally recognized and accepted by the whole society in China, and the utilization coverage among high-risk populations is low. Healthcare workers (HCWs) are important to the promotion and implementation of HIV drug prophylaxis strategy. This study analyzed the HIV drug prophylaxis services cascade (knowledge, attitude, and service) in HCWs, and explored the correlations between PEP and PrEP.

METHODS

A cross-sectional study was conducted among 1066 HCWs in 20 designated hospitals for HIV antiretroviral therapy in 20 cities in China. We collected information on participants' essential characteristics, HIV drug prophylaxis services cascade (knowledge, attitude, and service) and so on. The Chi-square test was used to analyse whether the differences and correlations between categorical variables were statistically significant, and Pearson contingency coefficient was used to analyse the strength of correlations. Multivariable logistic regression was used to analyse associated factors.

RESULTS

Among three stages of HIV drug prophylaxis services cascade, a high percentage of 1066 participants had knowledge of HIV drug prophylaxis (PEP: 78.2%, PrEP: 80.0%). Of them, almost all had supportive attitudes towards HIV drug prophylaxis (PEP: 99.6%, PrEP: 98.6%). Only about half of them would provide HIV drug prophylaxis services (PEP: 53.5%, PrEP: 48.5%). There were positive correlations between knowledge of PEP and PrEP (r = 0.292), between attitudes toward PEP and PrEP (r = 0.325), and between provision of PEP services and PrEP services (r = 0.555) in HCWs.

CONCLUSIONS

There was a positive correlation between PEP and PrEP in HCWs. At the stage of providing HIV drug prophylaxis services, training, advocacy and education for HCWs, should be targeted and also combine PEP and PrEP to maximize the effects, so as to improve the enthusiasm of HCWs to provide HIV drug prophylaxis services.

Sex Conservatism, Internalized Homonegativity, PrEP Stigma, and Intention to Use PrEP: A Study of Chinese-Speaking Gay and Bisexual Male Youth in Hong Kong

Pre-exposure prophylaxis (PrEP) stigma has been found to be a major barrier to PrEP acceptability and uptake. Research has found that different ethnic/cultural groups display varying levels of PrEP stigma. This article studies sex conservatism and internalized homonegativity as two sexuality- and culture-related aspects that influence PrEP stigma and intention to use PrEP. An online survey of 279 young gay and bisexual men in Hong Kong found that internalized homonegativity was positively associated with PrEP stigma. Respondents who were more conservative about sex showed lower intention to use PrEP, whereas those who had higher income and more positive attitudes about PrEP were more likely to express intention to use PrEP. This study provides novel empirical evidence for understanding PrEP stigma and uptake from a sexuality and cultural perspective. The influence of sexuality- and culture-related factors on PrEP stigma and uptake warrants greater attention, especially in the Asia-Pacific region.

Evidence of Potential Discriminatory HIV Pre-Exposure Prophylaxis (PrEP) Prescribing Practices for People Who Inject Drugs Among a Small Percentage of Providers in the U.S

INTRODUCTION

A large percentage of people who inject drugs (PWID) are living with HIV. Yet, rates of HIV pre-exposure prophylaxis (PrEP) use among PWID remain low. Stigma surrounding substance use and PWID have been identified as potential barriers to PrEP. This study examined healthcare providers' concerns regarding PWID and willingness to prescribe PrEP to PWID.

METHODS

An online, cross-sectional survey of a diverse group of healthcare providers in the 10 U.S. cities with the greatest HIV prevalence was conducted between July 2014 and May 2015. Participants responded to a patient vignette of a PWID and asked to indicate whether the patient would be a candidate for PrEP and why via free-response text. Descriptive statistics are reported using frequency measures. Bivariate analyses were conducted using chi-squared comparisons and logistical regression.

RESULTS

Survey data from 480 providers were included in analyses. Of the 480 responses, 85.5% were classified as PrEP aware, while 14.2% were PrEP unaware. Additionally, 82.6% indicated the patient would be a good candidate for PrEP, 4.4% believed the patient was not a good candidate for PrEP, and 13% were unsure. Among those who were unsure or would not prescribe PrEP (n = 84), open-ended responses indicated lack of knowledge (42.9%), concern about adherence (27.4%), concern about cost (4.8%), and bias (7.1%) as the primary reasons.

CONCLUSIONS

Although the majority of providers in this study did not demonstrate bias against PWID, our study found that limited PrEP knowledge and bias are barriers to PrEP prescription among PWID for some providers. Interventions are needed that increase PrEP awareness of CDC guidelines and reduce implicit bias among providers.

Tailored HIV Pre-exposure Prophylaxis (PrEP) Intervention Needs from a Latent Class Analysis Among U.S. Healthcare Providers

Interventions are needed to expand HIV pre-exposure prophylaxis (PrEP) prescribing practices among healthcare providers, but research classifying providers to determine tailored intervention needs is lacking. Providers reported demographics, factors related to HIV treatment and prevention experience, and PrEP-related factors such as knowledge and community protection beliefs via online survey. Latent class analysis grouped providers with similar patterns of HIV prevention- and treatment-related care and tested for associations with demographics and PrEP-related factors. Three distinct classes of providers emerged: (1) PrEP naïve, (2) PrEP aware, and (3) PrEP prescribers. Providers with lower community protection beliefs and staff capacity were more likely to be classified as PrEP naïve compared to aware (ps < 0.05). Providers with concerns about PrEP-related tasks and staff capacity were more likely to be classified as PrEP aware compared to prescribers (ps < 0.05). PrEP-naïve providers could benefit from continuing education, whereas PrEP-aware providers might benefit from capacity building and prescribing optimization interventions.

Context and Barriers to the Prescription of Nonoccupational Postexposure Prophylaxis Among HIV Medical Care Providers: National Internet-Based Observational Study in China

BACKGROUND

Nonoccupational postexposure prophylaxis (nPEP) is an effective HIV biomedical prevention strategy. The research and use of nPEP are mainly concentrated in the developed world, while little is known about the knowledge, attitudes, and practices of nPEP among HIV medical care providers in developing countries.

OBJECTIVE

We aimed to assess the nPEP knowledge and prescribing practice among HIV medical care providers in mainland China.

METHODS

HIV medical care providers were recruited in China during May and June 2019 through an online survey regarding nPEP-related knowledge, attitudes, and clinical prescription experiences. Multivariable logistic regression was performed to identify factors associated with prescribing nPEP among HIV medical care providers.

RESULTS

A total of 777 eligible participants participated in this study from 133 cities in 31 provinces in China. Of the participants, 60.2% (468/777) were unfamiliar with nPEP and only 53.3% (414/777) of participants ever prescribed nPEP. HIV care providers who worked in a specialized infectious disease hospital (vs general hospital, adjusted odds ratio [aOR] 2.49; 95% CI 1.85-3.37), had practiced for 6-10 years (vs 5 or fewer years, aOR 3.28; 95% CI 2.23-4.80), had practiced for 11 years or more (vs 5 or fewer years, aOR 3.75; 95% CI 2.59-5.45), and had previously prescribed occupational PEP (oPEP, aOR 4.90; 95% CI 3.29-7.29) had a significantly positive association with prescribing nPEP. However, unfamiliarity with nPEP (aOR 0.08; 95% CI 0.05-0.11), believing nPEP may promote HIV high-risk behavior (aOR 0.53; 95% CI 0.36-0.77) or result in HIV drug resistance (aOR 0.53; 95% CI 0.36-0.77) among key populations, and self-reported having no written oPEP guideline in place (aOR 0.53; 95% CI 0.35-0.79) were negatively associated with nPEP prescription behavior.

CONCLUSIONS

HIV medical care providers have insufficient nPEP knowledge and an inadequate proportion of prescribing, which may impede the scale-up of nPEP services to curb HIV acquisition. The implementation of tailored nPEP training or retraining to HIV medical care providers would improve this situation.
