CDC Clinical Guidelines on the Use of Doxycycline Postexposure Prophylaxis for Bacterial Sexually Transmitted Infection Prevention, United States, 2024.

No vaccines and few chemoprophylaxis options exist for the prevention of bacterial sexually transmitted infections (STIs) (specifically syphilis, chlamydia, and gonorrhea). These infections have increased in the United States and disproportionately affect gay, bisexual, and other men who have sex with men (MSM) and transgender women (TGW). In three large randomized controlled trials, 200 mg of doxycycline taken within 72 hours after sex has been shown to reduce syphilis and chlamydia infections by >70% and gonococcal infections by approximately 50%. This report outlines CDC's recommendation for the use of doxycycline postexposure prophylaxis (doxy PEP), a novel, ongoing, patient-managed biomedical STI prevention strategy for a selected population. CDC recommends that MSM and TGW who have had a bacterial STI (specifically syphilis, chlamydia, or gonorrhea) diagnosed in the past 12 months should receive counseling that doxy PEP can be used as postexposure prophylaxis to prevent these infections. Following shared decision-making with their provider, CDC recommends that providers offer persons in this group a prescription for doxy PEP to be self-administered within 72 hours after having oral, vaginal, or anal sex. The recommended dose of doxy PEP is 200 mg and should not exceed a maximum dose of 200 mg every 24 hours.Doxy PEP, when offered, should be implemented in the context of a comprehensive sexual health approach, including risk reduction counseling, STI screening and treatment, recommended vaccination and linkage to HIV PrEP, HIV care, or other services as appropriate. Persons who are prescribed doxy PEP should undergo bacterial STI testing at anatomic sites of exposure at baseline and every 3-6 months thereafter. Ongoing need for doxy PEP should be assessed every 3-6 months as well. HIV screening should be performed for HIV-negative MSM and TGW according to current recommendations.

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

The aim of this study was to examine trends in HIV incidence among men who have sex with men (MSM) relative to the scale up of Ending the HIV Epidemic (EHE) initiatives, including biomedical prevention strategies, and to describe racial inequities over time. A cross-sectional study, matching annual cohorts of New York City (NYC) Sexual Health Clinic (SHC) patients from 2010 to 2018 to the citywide HIV registry to identify seroconversions during 1 year of follow-up, through 2019. We examined HIV incidence for each annual cohort of MSM using diagnoses within 1 year after last negative HIV test. We calculated incidence rates and rate ratios (IRR) pooled across 3-year intervals (2010-2012, 2013-2015, 2016-2018) by race/ethnicity, age, neighborhood poverty level, recent STI diagnosis, and condom use during anal sex. There were 36 156 study visits among MSM attending NYC SHCs, including 37% among White MSM and 63% among MSM of color. From 2010 to 2018, HIV incidence decreased overall from 2.82 to 0.82/100 person-years, and among all race/ethnicity, age, poverty, STI, and condom use subgroups. For 2010-2012 vs. 2016-2018, adjusted IRRs (95% CI) increased for Black MSM [1.8 (1.3-2.6) vs. 6.0 (3.5-10.2)], Latino MSM [1.4 (1.0-2.0) vs. 4.0 (2.3-6.8)], and MSM of other races [1.0 (0.6-1.7) vs. 2.5 (1.3-4.9)] compared with White MSM. Black and Latino MSM seroconverted at significantly higher rates than White MSM in the same age groups and neighborhood poverty level. Despite decreases in HIV incidence among MSM, racial inequities were exacerbated over time. Addressing structural factors that impact racial inequities in risk of HIV should undergird EHE initiatives.

Awareness and Uptake of Pre-Exposure Prophylaxis (PrEP) for HIV Prevention Among Men who have Sex with Men in Nepal.

Pre-exposure prophylaxis (PrEP) is a highly effective biomedical prevention strategy that remarkably reduces HIV transmission risk. Although PrEP has been available in Nepal since 2019, very little is known about PrEP use among MSM in Nepal. This study aimed to examine PrEP awareness and its use among Nepali MSM and the factors influencing its adoption. A cross-sectional survey was conducted among MSM in Nepal between October and December 2022 (N = 250). Bivariate analysis and logistic regression were performed to determine factors associated with awareness and use of PrEP. In the study population, 59.6% of participants were aware of PrEP, however, only 30.4% of them had utilized it. The odds of PrEP awareness were higher among participants who had completed high school or above (aOR = 4.1; 95% CI = 1.8-9.6), those with health insurance coverage (aOR = 6.9; 95% CI = 2.1-22.3) and had tested for HIV (aOR = 21.2; 95% CI = 8.3-53.9). Similarly, participants who identified as gay (aOR = 3.4; 95% CI = 1.4-8.4), had visited a doctor within the past 6 months (aOR = 2.9; 95% CI = 1.2-6.5), had previously tested for HIV (aOR = 12.3; 95% CI = 3.4-44.7), and had been diagnosed with sexually transmitted infections (aOR = 7.0; 95% CI = 2.5-19.5) were more likely to have used PrEP. Our results highlight the critical importance of healthcare providers engaging in providing care for MSM, including facilitating as well as discussions about PrEP. In addition, there is a pressing need for innovative strategies (e.g., peer educators, social media, online facilitating technologies) to disseminate PrEP knowledge and reduce stigma surrounding PrEP.

Trends in illicit drug use and their association with HIV transmission risks from behavioural surveillance of Australian gay and bisexual men.

Investigating drug trends among Australian gay and bisexual men (GBM) is crucial for understanding levels of use and the potential for harm, including HIV transmission risk. Using repeated, national, cross-sectional survey data collected between 2012 and 2021 (69,567 surveys), trends of recent (previous 6 months) and frequent (weekly) drug use were analysed, using logistic regression models. The last round of data from each jurisdiction (6709 surveys) was used to compare GBM who reported no use, infrequent (less than weekly) use and frequent (at least weekly) use of party drugs to investigate the association between party drug use and HIV transmission risk, using multinomial logistic regression models. There was a significant upward trend in any recent drug use (from 58.4% in 2012 to 64.1% in 2021; p < 0.001). Frequent party drug use remained a minority practice over the period (consistently less than 3%). In cross-sectional analysis, frequent party drug users were more likely to report behaviours with HIV transmission risks, such as condomless anal intercourse without biomedical prevention strategies (30.0% vs. 13.1%; adjusted relative risk ratio [aRRR], 2.08; 95% CI, 1.24-3.47), weekly group sex (16.3% vs. 0.6%; aRRR, 12.36; 95% CI, 5.75-26.56) and more than 20 recent sexual partners (42.5% vs. 5.0%; aRRR, 21.44; 95% CI, 5.82-78.89), compared with GBM who did not use party drugs. Our findings suggest that the frequent use of party drugs remains a marker of HIV transmission risk among Australian GBM, despite the increased adoption of biomedical HIV prevention strategies over the past few years.

Changing characteristics of HIV-positive gay and bisexual men's relationships in the era of biomedical prevention.

To assess changes in personal and relationship characteristics among HIV-positive Australian gay and bisexual men (GBM) as rates of antiretroviral therapy (ART) and knowledge and confidence regarding the effectiveness of viral suppression in preventing HIV transmission have increased. Repeated behavioural surveillance of GBM recruited from venues, events, and online in seven Australian states and territories. HIV-positive participants were included. Trends in demographics, HIV treatment, and relationship characteristics were assessed with binary and multivariable logistic regression. A total of 3,643 survey responses (2016-2020) were included. Over time, HIV-positive GBM became less likely to identify as gay or report an Anglo-Australian ethnicity. The average length of time since HIV diagnosis increased and the frequency of attending HIV-related clinical appointments decreased. There were no changes in the reported number of recent sex partners or proportion reporting regular male partners over time. Among HIV-positive GBM in relationships, the proportion reporting HIV-positive partners decreased, and the proportion reporting HIV-negative partners increased. Levels of condomless sex with regular partners increased over time, however, this was concentrated among HIV-positive GBM in serodiscordant relationships. Findings suggest that increased accessibility and trust in biomedical prevention strategies have contributed to broader relationship and sexual opportunities for HIV-positive GBM in Australia. Our findings suggest future health promotion activities could highlight the social and relationship benefits of to further promote the effectiveness of treatment as prevention to further increase trust in it as an HIV prevention strategy among GBM.

"If they had a place to live, they would be taking medication": a qualitative study identifying strategies for engaging street-connected young people in the HIV prevention-care continuum in Kenya.

Street-connected young people (SCY) experience structural and social barriers to engaging in the HIV prevention-care continuum. We sought to elicit recommendations for interventions that may improve SCY's engagement along the HIV prevention-care continuum from healthcare providers, policymakers, community members and SCY in Kenya. This qualitative study was conducted in Uasin Gishu, Trans Nzoia, Bungoma, Nakuru and Kitale counties in Kenya between May 2017 and September 2018 to explore and describe the public perceptions of, and proposed and existing responses to, the phenomenon of SCY. This secondary analysis focuses on a subset of data interviews that investigated SCY's healthcare needs in relation to HIV prevention and care. We conducted 41 in-depth interviews and seven focus group discussions with 100 participants, of which 43 were SCY. In total, 48 participants were women and 52 men. Our analysis resulted in four major themes corresponding to stages in the HIV prevention-care continuum for key populations. We identified the need for an array of strategies to engage SCY in HIV prevention and testing services that are patient-centred and responsive to the diversity of their circumstances. The use of pre-exposure prophylaxis was a biomedical prevention strategy that SCY and healthcare providers alike stressed the need to raise awareness around and access to for SCY. Several healthcare providers suggested peer-based approaches for engaging SCY throughout the continuum. However, SCY heavily debated the appropriateness of using peer-based methods. Structural interventions, such as the provision of food and housing, were suggested as strategies to improve antiretroviral therapy adherence. This study identified contextually relevant interventions that should be adapted and piloted for use with SCY. Education and sensitization of SCY and healthcare providers alike were identified as possible strategies, along with affordable housing and anti-poverty strategies as cash transfers and provision of food. Peer-based interventions are a clear option but require SCY-specific adaptation to be implemented effectively.

Increasing Participation in a TelePrEP Program for Sexual and Gender Minority Adolescents and Young Adults in Louisiana: Protocol for an SMS Text Messaging-Based Chatbot.

Sexual and gender minority (SGM) adolescents and young adults (AYAs) are at increased risk of HIV infection, particularly in the Southern United States. Despite the availability of effective biomedical prevention strategies, such as pre-exposure prophylaxis (PrEP), access and uptake remain low among SGM AYAs. In response, the Louisiana Department of Health initiated the LA TelePrEP Program, which leverages the power of telemedicine to connect Louisiana residents to PrEP. A virtual TelePrEP Navigator guides users through the enrollment process, answers questions, schedules appointments, and facilitates lab testing and medication delivery. To increase the participation of SGM AYAs in the program, the TelePrEP program partnered with researchers to develop a chatbot that would facilitate access to the program and support navigator functions. Chatbots are capable of carrying out many functions that reduce employee workload, and despite their successful use in health care and public health, they are relatively new to HIV prevention. In this paper, we describe the iterative and community-engaged process that we used to develop an SMS text messaging-based chatbot tailored to SGM AYAs that would support navigator functions and disseminate PrEP-related information. Our process was comprised of 2 phases: conceptualization and development. In the conceptualization phase, aspects of navigator responsibilities, program logistics, and user interactions to prioritize in chatbot programming (eg, scheduling appointments and answering questions) were identified. We also selected a commercially available chatbot platform that could execute these functions and could be programmed with minimal coding experience. In the development phase, we engaged Department of Health staff and SGM AYAs within our professional and personal networks. Five different rounds of testing were conducted with various groups to evaluate each iteration of the chatbot. After each iteration of the testing process, the research team met to discuss feedback, guide the programmer on incorporating modifications, and re-evaluate the chatbot's functionality. Through our highly collaborative and community-engaged process, a rule-based chatbot with artificial intelligence components was successfully created. We gained important knowledge that could advance future chatbot development efforts for HIV prevention. Key to the PrEPBot's success was resolving issues that hampered the user experience, like asking unnecessary questions, responding too quickly, and misunderstanding user input. HIV prevention researchers can feasibly and efficiently program a rule-based chatbot with the assistance of commercially available tools. Our iterative process of engaging researchers, program personnel, and different subgroups of SGM AYAs to obtain input was key to successful chatbot development. If the results of this pilot trial show that the chatbot is feasible and acceptable to SGM AYAs, future HIV researchers and practitioners could consider incorporating chatbots as part of their programs.

Preventive Epidemiology of PrEP Use in African American Women With a Perceived HIV Risk

This study aims to examine the impact of education and household income on African American women’s perception of HIV risk on PrEP use. Secondary data from the Be-PrEPared dataset on 202 African American women’s attitudes toward condom use, biomedical prevention strategies, and risks associated with HIV transmission. African American women with a greater level of education and a perceived risk of HIV were more likely to utilize PrEP than African American women with a lower level of education and no reported risk of HIV. Additionally, women with a higher household income and perceived HIV risk were more likely to use PrEP as well. These associations were still present when taking HIV knowledge into account. It is the job of health practitioners and public health/health education professionals to improve PrEP interventions to be more culturally competent which will make adults more cognizant of the health issues related to HIV infection.

Awareness and use of HIV pre-exposure prophylaxis and factors associated with awareness among MSM in Beijing, China

Human immunodeficiency virus (HIV) sexual transmission among men who have sex with men (MSM) has increased markedly in Beijing, China in the past decade. Pre-exposure prophylaxis (PrEP) is a highly efficacious biomedical prevention strategy that remarkably reduces HIV-transmission risk. This study examined PrEP awareness among MSM and the factors influencing it. From April to July 2021, respondent-driven sampling was used to conduct a cross-sectional survey among MSM in Beijing, China. Demographic, behavior, and awareness data regarding PrEP were collected. The factors influencing PrEP awareness were assessed using univariate and multivariable logistic regression. In total, 608 eligible responders were included in the study. Among the respondents, 27.9% had PrEP awareness, 3.3% had taken PrEP, and 57.9% expressed interest in receiving PrEP, if required. Greater odds of PrEP awareness were associated with higher education level (adjusted odds ratio [aOR] 3.525, 95% confidence interval [CI] 2.013–6.173, P < 0.0001), greater HIV-related knowledge (aOR 3.605, 95% CI 2.229–5.829, P < 0.0001), HIV testing (aOR 2.647, 95% CI 1.463–4.788, P = 0.0013), and sexually transmitted infections (aOR 2.064, 95% CI 1.189–3.584, P = 0.0101). Lower odds of PrEP awareness were associated with higher stigma score (aOR 0.729, 95% CI 0.591–0.897, P = 0.0029). The findings indicate sub-optimal awareness and low utilization of PrEP in Beijing and highlight PrEP inequities among MSM with stigma. Strengthening the training of peer educators in disseminating PrEP knowledge and reducing stigma are critical for improving PrEP awareness.

Voluntary Medical Male Circumcision for HIV Prevention: a Global Overview.

With the promise of HIV prevention, there has been a scale-up of voluntary medical male circumcision (VMMC) in high HIV incidence/low circumcision prevalence nations worldwide. Nonetheless, debates over the implementation and the effectiveness and safety of the VMMC in real-world settings persist. We revisit the role of VMMC in HIV prevention to inform health professionals, policymakers, and advocates or opponents in this new era. There has been substantial progress on VMMC scale-up to date, but this has varied considerably by region. The evidence of solid and direct protection of VMMC is available for heterosexual men and older adolescent boys in sub-Saharan Africa. The protective effect in men who have sex with men is suggested by systematic reviews but is not confirmed by clinical trials. Sexual partners, including women, likely benefit indirectly from the increased VMMC coverage through a decreased risk of exposure to infected male partners. Fortunately, the preponderance of studies does not suggest higher sexual risk behaviors among circumcised men, so-called risk compensation. VMMC requires health systems strengthening and continued promulgation of other evidence-based HIV prevention strategies to be successful. Health authorities in high HIV incidence areas that have low circumcision coverage should implement VMMC within a context of complementary biomedical and behavioral prevention strategies.

Structural Stigma and Sexual Health Disparities Among Gay, Bisexual, and Other Men Who Have Sex With Men in Australia.

Discrimination and stigmatization at the institutional and sociocultural level (conceptualized as "structural stigma") has been associated with adverse health outcomes among sexual and gender minorities. However, few studies explore whether structural stigma is associated with sexual health outcomes. Addressing this gap, here, we explore this relationship among Australian gay, bisexual, and other men who have sex with men (GBM)-a population disproportionately affected by HIV. Using responses from the 2017 Australian Marriage Law Postal Survey, we operationalized structural stigma related to sexual minority status as the regional percentage of votes against legalizing same-sex marriage. These responses were then linked to national HIV behavioral surveillance data from Australian GBM (43,811 responses between 2015 and 2019). Controlling for a rich set of individual and regional level confounders, regression analyses were used to estimate the extent to which structural stigma was associated with testing for, and diagnoses of, HIV and sexually transmitted infections (STIs), and awareness and use of HIV prevention and treatment interventions (pre-exposure and postexposure prophylaxis, combination therapy, and HIV-related clinical care). Australian GBM living in regions with higher levels of structural stigma were less likely to undergo HIV/STI testing, receive HIV/STI diagnoses, and be taking, or aware of, biomedical prevention strategies. Among GBM living with HIV, structural stigma was associated with a reduced likelihood of being on combination therapy and fewer HIV-related clinical visits. Altogether, these results suggest that structural stigma may undermine HIV prevention strategies as well as adequate management of HIV infection among GBM.

Predictors of knowledge of and access to biomedical prevention among MSM and transgender men in Latin America: Results from the Latin American internet survey.

HIV is still a central public health issue in Latin America, disproportionally affecting key populations. Knowledge and access to biomedical prevention strategies, including treatment as prevention (TASP) or undetectable=untransmissible (U=U), pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP), are the first steps to increasing uptake. We used data from the Latin American MSM Internet Survey (LAMIS) to describe knowledge and access to biomedical HIV prevention strategies among gay, bisexual, transgender and other men who have sex with men (MSM) living in 18 Latin American countries. We compared LAMIS data across countries and according to age categories using frequencies and percentages. We also used multivariable models to explore whether age, gender identity, sexual identity, steady partnership, HIV status and education were independently associated with outcomes. In all, 55924 participants were included. Most were cisgender (99%) and identified as gay/homosexual (77%) or bisexual (17%). Schooling levels were very high, with 89% reporting highest attained education as tertiary level, university or post-graduation. In total, 16% had been previously diagnosed with HIV; of those, rates of undetectable viral load varied from 60% in Venezuela to 83% in Brazil. Overall, 54%, 54% and 52% of participants already knew about PEP, PrEP and U=U, respectively. Participants from Brazil and those aged between 26 and 55years, living with diagnosed HIV and having a gay/homosexual identity had greater levels of awareness about biomedical prevention strategies. Our study highlights gaps in HIV prevention campaigns directed to MSM in Latin America resulting in low uptake of biomedical prevention methods.

Beyond criminalization: reconsidering HIV criminalization in an era of reform.

This paper reviews recent studies examining the application of human immunodeficiency virus (HIV)-specific criminal laws in North America (particularly the United States and Canada). In the wake of the development of new biomedical prevention strategies, many states in the United States (US) have recently begun to reform or repeal their HIV-specific laws. These findings can help inform efforts to 'modernize' HIV laws (or, to revise in ways that reflect recent scientific advances in HIV treatment and prevention). Recent studies suggest that HIV-specific laws disproportionately impact Black men, white women, and Black women. The media sensationally covers criminal trials under these laws, especially when they involve Black defendants who they often describe in racialized terms as predators. Activists contest these laws and raise concerns about new phylogenetic HIV surveillance techniques that have the potential to be harnessed for law enforcement purposes. These findings collectively raise urgent concerns for the continued use of HIV-specific criminal laws. These policies disproportionately impact marginalized groups - particularly Black men. Media coverage of these cases often helps to spread misinformation and stigmatizing rhetoric about people living with HIV and promulgate racist stereotypes. Although well-intentioned, new phylogenetic HIV surveillance technologies have the potential to exacerbate these issues if law enforcement is able to gain access to these public health tools.

Novel strategies for prevention and treatment of antimicrobial resistance in sexually-transmitted infections.

Antimicrobial resistance in sexually acquired infection (STI) pathogens is an important global public health threat. There is an urgent need for novel STI treatment and prevention strategies to tackle the rising incidence of STIs in high-income settings and the static progress in low- and middle-income settings over the past decade. The purpose of this review was to describe the research outlining the emergence of resistance in common STI pathogens and new strategies for their treatment and prevention. Rates of STIs have dramatically increased over the past decade. Further, antimicrobial resistance to first-line agents among key STI pathogens continues to emerge globally. Recent findings demonstrate promising results regarding the efficacy of novel antimicrobial treatment strategies for these pathogens, including several new, repurposed and unique combinations of antimicrobials. In addition, a number of new biomedical prevention strategies, such as antibacterial mouthwash and doxycycline chemoprophylaxis, are being investigated as novel prevention strategies for bacterial STIs. Significant progress has been made in the development of novel antimicrobials for the treatment of antimicrobial-resistant sexually acquired pathogens. However, due to the rapid development of resistance to antimicrobials demonstrated by these pathogens in the past, further research and development of effective prevention strategies should be prioritized.

Awareness and use of nonoccupational HIV post-exposure prophylaxis and factors associated with awareness among MSM in Beijing, China.

BackgroundHuman immunodeficiency virus (HIV) sexual transmission among men who have sex with men (MSM) has increased markedly in Beijing, China, during the past decade. Nonoccupational HIV post-exposure prophylaxis (nPEP) is a highly efficacious biomedical prevention strategy that significantly reduces HIV-transmission risk. This study examined nPEP awareness among MSM and the factors influencing it.MethodsConsecutive, cross-sectional MSM surveys were conducted from April to August of 2018 and 2019. Demographic data as well as that on behavior and awareness regarding nPEP was collected. Factors influencing nPEP awareness were assessed using univariate and multivariable logistic regression.ResultsThere were 1,202 eligible responders recruited. Of the responders, 42.5% had nPEP awareness, and 59.9% expressed interest in receiving nPEP in the future, if required. Greater odds of nPEP awareness were associated with younger age, higher education level (adjusted odds ratio [aOR]: 4.011, 95% confidence interval [CI]: 2.834–5.678, P<0.001), higher income, use of the Internet to meet sexual partners (aOR: 2.016, 95% CI: 1.481–2.744, P<0.001), greater HIV-related knowledge (aOR: 3.817, 95% CI: 1.845–7.899, p<0.001), HIV testing (aOR: 2.584, 95% CI: 1.874–3.563, p<0.001), and sexually transmitted infections (aOR: 1.736, 95% CI: 1.174–2.569, P = 0.006). Lower odds of nPEP awareness were associated with greater stigma score (aOR: 0.804, 95% CI: 0.713–0.906, P<0.001).ConclusionsThe findings indicate suboptimal awareness and low utilization of nPEP in Beijing and highlight nPEP inequities among MSM with stigma. Strengthening the training of health service providers and peer educators in reducing stigma and disseminating nPEP knowledge is imperative.

Pre-exposure prophylaxis awareness, acceptability and potential stigma among medical and non-medical clinic staff in methadone treatment settings in northern New Jersey: The key role of non-medical staff in enhancing HIV prevention

BackgroundHIV prevention is needed among people who use drugs (PWUD) due to mixing sex and drugs, selling/trading sex, and/or injecting drugs. Pre-exposure prophylaxis (PrEP) is an extremely effective biomedical HIV prevention strategy, but uptake remains low among communities most in need of HIV prevention, including PWUD. Previous studies have found that providers are less willing to prescribe PrEP to PWUD, yet PWUD express high levels of PrEP acceptance. More research is needed to understand how people who provide substance use treatment services think about PrEP to maximize this biomedical prevention strategy. MethodsThe study conducted semistructured interviews with 29 staff members in two methadone clinic settings in urban northern New Jersey. Staff members included medical providers, methadone counselors, intake coordinators, front desk staff, lab technicians, security guards, and administrative/leadership personnel. ResultsAll staff recognized the need for HIV prevention among their patient populations, but most were either unaware of PrEP or unfamiliar with its purpose and how it works. Medical providers were more likely to have some PrEP knowledge in comparison to counselors and other staff, but the former largely did not have in-depth knowledge. Among those familiar with PrEP, many confused PrEP with HIV medication, as Truvada was the only FDA-approved PrEP at the time of the study. About half of participants expressed clear support for PrEP, while the other half expressed mixed or negative attitudes related to HIV, sexual behavior, and mistrust of the medication. Both the positive and negative perceptions entailed stigmatizing elements. RecommendationsDue to patients' frequent interactions with non–medical staff (e.g., front desk staff, lab technicians, etc.), all staff, not only medical personnel, should be aware of PrEP and comfortable discussing it to foster well-informed, nonjudgmental conversations about HIV prevention with patients. PrEP education should specifically address HIV and sexual-related stigma, as even positive perceptions of PrEP may entail stigmatizing elements.

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

BackgroundNonoccupational 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.ObjectiveWe aimed to assess the nPEP knowledge and prescribing practice among HIV medical care providers in mainland China.MethodsHIV 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.ResultsA 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.ConclusionsHIV 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.

HIV pre-exposure prophylaxis (PrEP) knowledge, familiarity, and attitudes among United States healthcare professional students: A cross-sectional study.

The United States' initiative to End the HIV Epidemic by 2030 includes a primary goal to reduce new HIV infections by 90 percent. One key contributor to this plan is HIV pre-exposure prophylaxis (PrEP). While knowledge and acceptance of PrEP among clinicians is growing, few studies have assessed knowledge and awareness among future healthcare professionals in academic training programs. The present study aimed to assess and compare healthcare trainees' awareness, knowledge, and familiarity with PrEP prescribing guidelines to better understand and prevent gaps in academic training regarding PrEP. A cross-sectional web-based survey of medical, nurse practitioner, and pharmacy students enrolled at two universities was conducted between October 2017 and January 2018. The study assessed participants' awareness, knowledge, and familiarity with PrEP prescribing guidelines and willingness to prescribe PrEP and refer to another healthcare provider. The survey was completed by 744 participants (response rate=36.2%). Overall, PrEP awareness was high though PrEP knowledge was low. There were significant differences among student groups in domains of interest. Pharmacy students had the greatest PrEP knowledge, awareness, and familiarity with prescribing guidelines. However, medical students reported the greatest comfort with performing PrEP-related clinical activities and willingness to refer a candidate to another provider. Study findings enhance our understanding of healthcare professional students' perspectives of PrEP as a biomedical prevention strategy for HIV. The gaps in students' knowledge offer opportunities for the development of educational strategies to support HIV prevention among future healthcare professionals.

PrEP Attitudes from MSM and Transwomen in the Largest Suburban HIV Epidemic in the USA

Long Island has the largest suburban human immunodeficiency virus (HIV) epidemic in the USA with an estimated 5,730 people living with HIV/AIDS in 2018 (most recent data). While pre-exposure prophlaxis (PrEP) is a promising primary intervention strategy to reduce HIV incidence, the uptake of this biomedical prevention strategy has been very low. Factors such as homophobia, stigma, and discrimination against men who have sex with men (MSM) and transgender women still exist in the community through provider interactions, and negatively affect the well-being of these populations. The aim of this study was to examine PrEP knowledge, attitudes, and practices among MSM and transgender women on Long Island. Fifteen interviews were conducted with MSM and transgender women; interviews were transcribed and analyzed using an inductive method involving constant comparison. Four main themes emerged from our analysis: (1) participants have high agency in accessing and utilizing HIV-related biomedical prevention services; (2) participants had limited understanding of what PrEP is and what it means to be on PrEP; (3) PrEP-user stigma and costs are the biggest barriers to initiating and remaining on PrEP; and (4) E-health, credible Internet-resources, and technology-based programming are needed to support current and potential PrEP users. This study, the first study of PrEP attitudes in a suburban environment, highlights the need for evidence-based health promotion and sexual health interventions designed for suburban gender and sexual minorities that are evidence-based and go beyond goal setting and improving self-efficacy.

Awareness and Willingness to Use Biomedical Prevention Strategies for HIV Among Sexual and Gender Minority Youth: Results From a National Survey

PurposeSexual and gender minority youth (SGM), an umbrella term encompassing gay, bisexual, and transgender youth, experience disproportionately high rates of new HIV infections, and recent advances in biomedical HIV prevention modalities hold promise in reducing new infections. However, the extent to which SGM youth are aware of and willing to use these modalities is unknown. MethodsUsing data from the Survey of Today's Adolescents Relationships and Transitions, we analyze awareness of and willingness to take HIV pre-exposure prophylaxis (PrEP), nonoccupational HIV post-exposure prophylaxis, and rectal microbicides among adolescent sexual minority males aged 13–18 years and transgender youth aged 13–24 years. ResultsOverall, we found a majority of our respondents were not aware of any of these prevention modalities. Across both subsamples, age and outness to a health care provider were associated with increased PrEP awareness, and any anal sex was associated with PrEP willingness. ConclusionsThese findings highlight the importance of provider education on how to discuss SGM issues with patients and educate them about HIV prevention options.
