Cost-Effectiveness of Interventions to Improve HIV Pre-exposure Prophylaxis Initiation, Adherence, and Persistence Among Men Who Have Sex With Men.

To help achieve Ending the HIV Epidemic (EHE) goals of reducing new HIV incidence, pre-exposure prophylaxis (PrEP) use and engagement must increase despite multidimensional barriers to scale-up and limitations in funding. We investigated the cost-effectiveness of interventions spanning the PrEP continuum of care. Men who have sex with men in Atlanta, GA, a focal jurisdiction for the EHE plan. Using a network-based HIV transmission model, we simulated lifetime costs, quality-adjusted life years (QALYs), and infections averted for 8 intervention strategies using a health sector perspective. Strategies included a status quo (no interventions), 3 distinct interventions (targeting PrEP initiation, adherence, or persistence), and all possible intervention combinations. Cost-effectiveness was evaluated incrementally using a $100,000/QALY gained threshold. We performed sensitivity analyses on PrEP costs, intervention costs, and intervention coverage. Strategies averted 0.2%-4.2% new infections and gained 0.0045%-0.24% QALYs compared with the status quo. Initiation strategies achieved 20%-23% PrEP coverage (up from 15% with no interventions) and moderate clinical benefits at a high cost, while adherence strategies were relatively low cost and low benefit. Under our assumptions, the adherence and initiation combination strategy was cost-effective ($86,927/QALY gained). Sensitivity analyses showed no strategies were cost-effective when intervention costs increased by 60% and the strategy combining all 3 interventions was cost-effective when PrEP costs decreased to $1000/month. PrEP initiation interventions achieved moderate public health gains and could be cost-effective. However, substantial financial resources would be needed to improve the PrEP care continuum toward meeting EHE goals.

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

BackgroundHIV 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.ObjectiveThe 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.MethodsThis 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.ResultsThe 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.ConclusionsBased 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.International Registered Report Identifier (IRRID)DERR1-10.2196/31928

HIV Preexposure Prophylaxis Care Continuum Among Individuals Receiving Medication for Opioid Use Disorder, South Carolina, 2020-2021.

We implemented the HIV preexposure prophylaxis (PrEP) care continuum among individuals receiving medication for opioid use disorder (MOUD). We screened HIV-negative MOUD participants for PrEP eligibility by assessing injection drug use risk factors and sexual behaviors. Implementation of the PrEP care continuum was challenging; less than a third of MOUD participants were aware of PrEP, and very few initiated PrEP. Findings should promote the development of effective interventions to increase engagement in PrEP during MOUD treatment.

A Scoping Review Investigating Relationships between Depression, Anxiety, and the PrEP Care Continuum in the United States.

Men who have sex with men and transgender women in the United States are at increased risk for HIV and may benefit from pre-exposure prophylaxis (PrEP), a once-a-day pill to prevent HIV. Due to stigma and discrimination, sexual and gender minority (SGM) populations are also at risk for depression and anxiety. This scoping review sought to identify literature addressing relationships between the PrEP care continuum, depression, and anxiety among SGM individuals and others at high risk for HIV. We conducted a systematic review of four databases (i.e., PubMed, PsycInfo, Web of Science, Google Scholar) and identified 692 unique articles that were screened for inclusion criteria, with 51 articles meeting the final inclusion criteria. Data were extracted for key study criteria (e.g., geographic location, participant demographics, study design, main findings). Results suggest that while depression and anxiety are not associated with PrEP awareness or willingness to use, they can be barriers to seeking care and to PrEP adherence. However, empirical studies show that taking PrEP is associated with reductions in anxiety. Findings suggest the need to implement mental health screenings in PrEP clinical care. In addition, addressing systemic and structural issues that contribute to mental health disorders, as well as PrEP-related barriers, is critical.

Metrics of HIV Pre-exposure Prophylaxis (PrEP) Implementation Before and After a Multidisciplinary Task Force at an Academic Institution.

There is a paucity of guidance on HIV pre-exposure prophylaxis (PrEP) implementation in an academic medical center. The objectives of this study were to describe interventions by a multidisciplinary PrEP task force at an academic medical center and compare metrics of PrEP implementation pre- and post-creation of this entity. The interventions of the task force are described within the rubric of the PrEP care continuum. Participants were adults prescribed PrEP for greater than or equal to 30 days at 9 clinical sites across a university health system. Metrics of PrEP implementation were compared over 12-month intervals before and after the creation of the task force. An increased proportion of participants had HIV testing within 7 days of new PrEP prescriptions (92% vs 63%, P < .001) and were prescribed PrEP in increments of 90 days or shorter (74% vs 56%, P < .001) after the creation of the task force. There were higher rates of testing for bacterial sexually transmitted infections in men who had sex with men and transgender women in the post-intervention compared with pre-intervention period. A multidisciplinary team that focuses on optimizing PrEP delivery along each step of the care continuum may facilitate PrEP scale-up and best practices in an academic setting.

PrEP Care Continuum Engagement Among Persons Who Inject Drugs: Rural and Urban Differences in Stigma and Social Infrastructure

Pre-exposure prophylaxis (PrEP) is a medication that prevents HIV acquisition, yet PrEP uptake has been low among people who inject drugs. Stigma has been identified as a fundamental driver of population health and may be a significant barrier to PrEP care engagement among PWID. However, there has been limited research on how stigma operates in rural and urban settings in relation to PrEP. Using in-depth semi-structured qualitative interviews (n = 57) we explore PrEP continuum engagement among people actively injecting drugs in rural and urban settings. Urban participants had more awareness and knowledge. Willingness to use PrEP was similar in both settings. However, no participant was currently using PrEP. Stigmas against drug use, HIV, and sexualities were identified as barriers to PrEP uptake, particularly in the rural setting. Syringe service programs in the urban setting were highlighted as a welcoming space where PWID could socialize and therefore mitigate stigma and foster information sharing.

Predictors of Anticipated PrEP Stigma among Women with Self-Reported Problematic Substance Use: Implications for Engaging Women in the PrEP Care Continuum.

Pre-exposure prophylaxis (PrEP) is an effective HIV prevention method, but it has been underutilized by women. Anticipated stigma regarding use of PrEP is a contributing factor in the underutilization of this prevention strategy. The current study explored the relationships among PrEP stigma, sex risk (i.e., inconsistent condom use, condomless sex with persons of unknown serostatus, or sex in exchange for money or drugs), substance use, attitudes toward HIV testing, and medical mistrust. Participants were 106 primarily ethnic-minority women who reported recent substance use and agreed to participate in a study exploring HIV prevention attitudes. Within this sample, the majority of participants had one or more CDC-defined PrEP indications. Findings indicate that medical mistrust was associated with perceived PrEP stereotypes and HIV testing attitudes. These results provide some insight into reasons for low PrEP uptake among women at risk for HIV. Implications for HIV prevention with women are discussed.

Evaluation of an HIV Pre-Exposure Prophylaxis Referral System: From Sexual Health Center to Federally Qualified Health Center Pre-Exposure Prophylaxis Clinic.

Innovative delivery strategies are needed to facilitate access to HIV pre-exposure prophylaxis (PrEP). The objective of this study was to evaluate a navigator-facilitated PrEP referral process from a sexual health center (SHC) to a co-located PrEP clinic as an alternative delivery model. Electronic health record (EHR) data were used to calculate the number of clients seen at the SHC in 2019. Charts were manually reviewed to determine whether a PrEP clinic referral was made and document type of referral method: face-to-face appointment scheduling with the navigator (warm handoff), EHR messaging to navigator to schedule the appointment at a later time (EHR message), or provision of navigator's contact information to the client (card only). In 2019, 2481 unique potentially PrEP-eligible clients were seen at the SHC; 220 (9%) received a PrEP referral. Of referred clients, median age was 30 years (interquartile range, 24-34), 182 (83%) were male, 89 (40%) were non-Hispanic Black, and 24 (11%) were Latinx. In total, 94/220 (43%) referred clients attended an initial PrEP visit with a provider, and the proportion attending by referral method was 81%, 36%, and 27% for warm handoff, EHR message, and card only, respectively (p < 0.0001). Despite co-location of these two clinics, there were significant drop-offs along the PrEP care continuum for this referral system. Warm handoff was the most effective referral method, but further efforts are needed to understand barriers to referral. Implementation of same-day PrEP services at SHCs is one potential solution to engaging additional clients.

Perceived HIV Acquisition Risk and Low Uptake of PrEP Among a Cohort of Transgender Women With PrEP Indication in the Eastern and Southern United States.

Preexposure prophylaxis (PrEP) is effective in preventing HIV among adherent users. However, PrEP uptake among transgender women is low, and current prescribing guidelines from the Centers for Disease Control and Prevention (CDC) are not specific to transgender women. Self-perceived risk of HIV among those who are PrEP-indicated is not well understood. This cross-sectional analysis included 1293 transgender women screened at baseline from March 2018 to May 2020 for a multisite, prospective cohort study. We compared the prevalence of PrEP indication using current CDC prescribing criteria versus transgender women-specific criteria developed by study investigators with community input. We identified factors associated with study-specific PrEP indication and factors associated with self-perceived low to no HIV risk among those who were PrEP-indicated. We also calculated descriptive statistics to depict the PrEP care continuum. PrEP indication prevalence using transgender women-specific criteria was 47% (611), 155 more than who were identified using the CDC criteria. Eighty-three percent were aware of PrEP, among whom 38% had ever used PrEP. Among PrEP ever users, 63% were using PrEP at the time of the study. There were 66% of current PrEP users who reported 100% adherence within the previous 7 days. Among those who were PrEP-indicated, 13% were using and adherent to PrEP at the time of the study. More than half (55%) of PrEP-indicated participants had low or no self-perceived HIV risk. These findings suggest that further guidance is needed for health care providers in prescribing PrEP to transgender women. Greater uptake and adherence are also needed for optimal effectiveness.

Characterization of HIV Preexposure Prophylaxis Use Behaviors and HIV Incidence Among US Adults in an Integrated Health Care System

Long-term follow-up is needed to evaluate gaps in HIV preexposure prophylaxis (PrEP) care delivery and to identify individuals at risk for falling out of care. To characterize the PrEP continuum of care, including prescription, initiation, discontinuation, and reinitiation, and evaluate incident HIV infections. This retrospective cohort study used data from the electronic health records (EHR) at Kaiser Permanente Northern California to identify individuals aged 18 years and older who received PrEP care between July 2012 and March 2019. Individuals were followed up from date of linkage (defined as a PrEP referral or PrEP-coded encounter) until March 2019, HIV diagnosis, discontinuation of health plan membership, or death. Data were analyzed from December 2019 to January 2021. Sociodemographic factors included age, sex, race and ethnicity, and neighborhood deprivation index, and clinical characteristics were extracted from the EHR. The primary outcomes were attrition at each step of the PrEP continuum of care and incident HIV infections. Among 13 906 individuals linked to PrEP care, the median (interquartile range [IQR]) age was 33 (27-43) years, 6771 individuals (48.7%) were White, and 13 227 (95.1%) were men. Total follow-up was 26 210 person-years (median [IQR], 1.6 [0.7-2.8] years). Of individuals linked to PrEP care, 88.1% (95% CI, 86.1%-89.9%) were prescribed PrEP and of these, 98.2% (95% CI, 97.2%-98.8%) initiated PrEP. After PrEP initiation, 52.2% (95% CI, 48.9%-55.7%) discontinued PrEP at least once during the study period, and 60.2% (95% CI, 52.2%-68.3%) of these individuals subsequently reinitiated. Compared with individuals aged 18 to 25 years, older individuals were more likely to receive a PrEP prescription (eg, age >45 years: hazard ratio [HR], 1.21 [95% CI, 1.14-1.29]) and initiate PrEP (eg, age >45 years: HR, 1.09 [95% CI, 1.02-1.16]) and less likely to discontinue (eg, age >45 years: HR, 0.46 [95% CI, 0.42-0.52]). Compared with White patients, African American and Latinx individuals were less likely to receive a PrEP prescription (African American: HR, 0.74 [95% CI, 0.69-0.81]; Latinx: HR, 0.88 [95% CI, 0.84-0.93]) and initiate PrEP (African American: HR, 0.87 [95% CI, 0.80-0.95]; Latinx: HR, 0.90 [95% CI, 0.86-0.95]) and more likely to discontinue (African American: HR, 1.36 [95% CI, 1.17-1.57]; Latinx: 1.33 [95% CI, 1.22-1.46]). Similarly, women, individuals with lower neighborhood-level socioeconomic status (SES), and persons with a substance use disorder (SUD) were less likely to be prescribed (women: HR, 0.56 [95% CI, 0.50-0.62]; lowest SES: HR, 0.72 [95% CI, 0.68-0.76]; SUD: HR, 0.88 [95% CI, 0.82-0.94]) and initiate PrEP (women: HR, 0.71 [95% CI, 0.64-0.80]; lower SES: HR, 0.93 [95% CI, 0.87-.0.99]; SUD: HR, 0.88 [95% CI, 0.81-0.95]) and more likely to discontinue (women: HR, 1.99 [95% CI, 1.67-2.38]); lower SES: HR, 1.40 [95% CI, 1.26-1.57]; SUD: HR, 1.23 [95% CI, 1.09-1.39]). HIV incidence was highest among individuals who discontinued PrEP and did not reinitiate PrEP (1.28 [95% CI, 0.93-1.76] infections per 100 person-years). These findings suggest that gaps in the PrEP care continuum were concentrated in populations disproportionately impacted by HIV, including African American individuals, Latinx individuals, young adults (aged 18-25 years), and individuals with SUD. Comprehensive strategies to improve PrEP continuum outcomes are needed to maximize PrEP impact and equity.

Reaching Those Most at Risk for HIV Acquisition: Evaluating Racial/Ethnic Disparities in the Preexposure Prophylaxis Care Continuum in Baltimore City, Maryland.

Reducing HIV incidence requires addressing persistent racial/ethnic disparities in HIV burden. Our goal was to evaluate preexposure prophylaxis (PrEP) delivery, overall and relative to community need, among 7 clinical sites participating in a health department-led demonstration project to increase PrEP in Baltimore city, MD. PrEP care continuum stages (screened, indicated, referred, linked, evaluated, prescribed) were examined among HIV-negative individuals receiving services at participating sites between September 30, 2015 and September 29, 2019. Community need was defined using information on new HIV diagnoses (2016-2018). Differences in care continuum progression by demographics/priority population and comparison of demographic compositions between care continuum stages and new HIV diagnoses were examined using modified Poisson regression and χ2 tests, respectively. Among 25,886 PrEP-screened individuals, the majority were non-Hispanic (NH) black (81.1%, n = 20,998), cisgender male (61.1%, n = 15,825), and heterosexual (86.7%, n = 22,452). Overall, 31.1% (n = 8063) were PrEP-indicated; among whom, 56.8% (n = 4578), 15.6% (n = 1250), 10.8% (n = 868), and 9.0% (n = 722) were PrEP-referred, linked, evaluated, and prescribed, respectively. Among 2870 men who have sex with men (MSM), 18.7% (n = 538) were PrEP-prescribed. Across all groups, the highest attrition was between PrEP-referred and PrEP-linked. NH-black race (vs. NH-white) was independently associated with lower likelihood of PrEP prescription (aPR, 0.89; 95% confidence interval, 0.81 to 0.98 controlling for age/gender). Relative to the demographic composition of new HIV diagnoses, fewer NH-blacks (80.2% vs. 54.3%) and more NH-whites (10.7% vs. 30.3%) and MSM were PrEP prescribed (55.2% vs. 74.5%). This project showed promise delivering PrEP referrals and prescriptions overall and to MSM. Substantial improvement is needed to improve linkage overall and to decrease disparities in PrEP prescriptions among NH-blacks. Future work should focus on addressing service gaps that hinder PrEP utilization.

Education, Perceptions, and Delivery: Factors Shaping the Perceived Role in the Pre-Exposure Prophylaxis (PrEP) Care Continuum Among a Sample of Osteopathic Medical Students.

Pre-exposure prophylaxis (PrEP) uptake has been suboptimal despite its demonstrated efficacy in reducing the risk of HIV acquisition. Medical education is one distal determinant that shapes medical providers' perceived role in the PrEP care continuum. However, there is limited understanding of how osteopathic medical students and those wanting to practice in rural areas perceive their role in the PrEP care continuum in the domains of PrEP awareness, uptake, and adherence and retention. Twenty-one semistructured interviews were conducted (March 2019-April 2020) to assess what shapes osteopathic medical students' perceived role in the PrEP care continuum. Participants noted a lack of adequate sexual health training, personal perceptions concerning PrEP use, and ambiguity concerning which of the medical specialties should deliver PrEP. Osteopathic medical schools can incorporate more inclusive and holistic sexual health and PrEP curricula to address these barriers and better prepare osteopathic medical students for their future role in the PrEP care continuum.

Pre-Exposure Prophylaxis Care Continuum, Barriers, and Facilitators among Black Men Who Have Sex with Men in the United States: A Systematic Review and Meta-Analysis.

Pre-exposure prophylaxis (PrEP) represents a viable HIV prevention tool for black men who have sex with men (BMSM). However, aggregated evidence regarding the presentations and determinants of the PrEP continuum (e.g., awareness, willingness, intention, uptake and adherence) remains absent to empirically inform future intervention efforts. We meta-analytically summarized the prevalence and qualitatively synthesized key barriers/facilitators of the stages of the PrEP continuum among a pooled sample of 42,870 BMSM aggregated from 56 published studies. Our random-effect models indicated a pooled prevalence of PrEP awareness (50.8%, 95% CI: 43.6-58.0%, willingness/intention (58.2%, 95% CI: 52.0-68.1%) and uptake (15.5%, 95% CI: 12.8-18.2%). Qualitative summary revealed that perception of HIV risk, intersectional/PrEP-related stigma and medical mistrust were among the most quoted factors that influence PrEP use. BMSM remain underrepresented in key stages of the PrEP continuum. Futures interventions are continuously needed to target multilevel barriers/facilitators to enhance the PrEP continuum among BMSM.

973. PrEP Care Continuum among Transgender Women at a Patient-Centered PrEP Program in Atlanta, GA

BackgroundHIV disproportionally affects transgender women (TGW) of color, with a prevalence of 26% and 44% among Latinx and Black TGW, respectively. Low medication adherence likely contributed to suboptimal pre-exposure prophylaxis (PrEP) efficacy among TGW in clinical trials, but real-world PrEP outcome data for TGW is limited. In this study, we developed the PrEP care continuum for TGW referred to a PrEP program at a large, safety-net urban hospital in the Southeast.Figure 1. PrEP care continuum of TGW referred a PrEP program. Referrals include all TGW referred to PrEP clinic, eligibility includes all those referred who were deemed eligible for PrEP, linkage refers to those eligible who had ongoing care at the PrEP clinic, prescription refers to those who received their first prescription of PrEP, initiation includes those who started taking the PrEP they were prescribed, and persistence includes those who had a visit within 6 months of study end. MethodsWe analyzed data for those referred to the PrEP program from 3/2018 to 2/2020. We determined the proportion of TGW who were linked to the program, provided a PrEP prescription, started PrEP, and persisted in PrEP care, defined as having at least one follow-up visit within 6 months. Using a multivariate regression model, including age, race, ethnicity, mental health co-morbidities, and substance use, we determined factors associated with persistence in PrEP care. We calculated rates of sexually transmitted infections (STIs) and HIV incidence.ResultsOf the 321 total referrals for PrEP, 42 (13%) were TGW. 81% of TGW were referred from a co-located gender clinic. Median age was 28.5 years (IQR 23-34), 62% were Black, 21% had mental health co-morbidities, 45% used substances, and 35% engaged in transactional sex. Of all TGW who were referred, 37 (88%) were eligible for PrEP and linked to care, 36 (85.7%) were prescribed and initiated PrEP, and 22 (52.4%) persisted in care at the end of the study period. There were no factors associated with persistence in PrEP care. The most common STIs during the first visit were pharyngeal gonorrhea (22.7%) and syphilis (16.7%). STI incidence was highest for rectal chlamydia (12.5%) and pharyngeal gonorrhea (6.5%). There was one HIV seroconversion during the study period.ConclusionIn a public hospital-based PrEP clinic in Atlanta with a co-located gender clinic, TGW had high rates of linkage to care and PrEP prescription and initiation, despite high rates of mental health diagnoses and substance use. However, there was a significant drop-off in persistence. STI prevalence and incidence were high, but there was only one HIV seroconversion, highlighting the potential benefits of PrEP. Future studies are needed to assess interventions to optimize persistence in PrEP care among TGW.DisclosuresBradley L. Smith, PharMD, AAHIVP, Gilead Sciences, Inc (Advisor or Review Panel member)

104. Evaluation of a Prep Referral System: From Sexual Health Center to Federally Qualified Health Center Prep Clinic

BackgroundIn the United States, less than one-quarter of those who are eligible for pre-exposure prophylaxis (PrEP) have been prescribed the medication. Innovative strategies of PrEP delivery are needed to facilitate access and overcome barriers to care. The objective of this study was to evaluate the referral process from a sexual health center (SHC) to a co-located PrEP clinic as an alternative model of PrEP care.MethodsAn initial report was generated from the electronic health record (EHR) to determine the number of patients seen at the SHC in 2019. Charts were then manually reviewed to determine whether a PrEP clinic referral was made. For those referred, we determined the method of the referral: PrEP clinic navigator met the patient at the SHC (handoff), the navigator was messaged in the EHR to then schedule the appointment (EHR message), or the patient was provided a card with the navigator’s contact information (card). We also determined whether patients had subsequent visits at the PrEP clinic or SHC.ResultsFrom January to December 2019, there were 3570 unique patients seen at the SHC, and 240 (6.7%) were referred to the PrEP clinic. Of 240 referred patients, median age was 29 years; 95 (40%) were non-Hispanic Black and 25 (11%) were Latinx. The majority (n=198, 83%) were male, 32 (13%) were cisfemale, and 9 (4%) were transfemale. An STI was diagnosed on the day of the clinic visit for 116 (49%) patients. Of those who were MSM, 75 (51%) had been diagnosed with an STI in the previous 6 months. In total, 106 referred patients attended an initial PrEP visit and the proportion attending the visit by method of referral was 81%, 38%, and 22% for handoff, EHR message, and card, respectively (p< .0001). Of the 108 patients who attended an initial PrEP visit, 66 (61%) had a subsequent PrEP visit. Of those who did not attend a PrEP visit, 36 (27%) had a subsequent visit at the SHC.Figure 1. Method of Referral from SHC to PrEP Clinic ConclusionDespite co-location of these two clinics, there are significant drop-offs along the PrEP care continuum for this referral system. Navigator-facilitated handoff was the most effective method of referral from SHC to PrEP Clinic, but further efforts are needed to understand barriers to referral. Implementation of rapid PrEP provided at the SHC may be one possible solution to engaging additional patients in PrEP services.Disclosures Meredith E.

Addressing Unhealthy Alcohol Use and the HIV Pre-exposure Prophylaxis Care Continuum in Primary Care: A Scoping Review

Individuals with unhealthy alcohol use are at increased risk for HIV acquisition and may benefit from receiving HIV pre-exposure prophylaxis (PrEP) in primary care settings. To date, literature synthesizing what is known about the impact of unhealthy alcohol use on the PrEP care continuum with a focus on considerations for primary care is lacking. We searched OVID Medline and Web of Science from inception through March 19, 2020, to examine the extent, range, and nature of research on PrEP delivery among individuals with unhealthy alcohol use in primary care settings. We identified barriers and opportunities at each step along the PrEP care continuum, including for specific populations: adolescents, people who inject drugs, sex workers, and transgender persons. Future research should focus on identification of candidate patients, opportunities for patient engagement in novel settings, PrEP implementation strategies, and stigma reduction.

Online Navigation for Pre-Exposure Prophylaxis via PleasePrEPMe Chat for HIV Prevention: Protocol for a Development and Use Study.

BackgroundPre-exposure prophylaxis is an HIV medication taken by an individual who is HIV-negative to prevent infection before exposure to the virus. Numerous clinical studies in various communities have shown high rates of effectiveness when pre-exposure prophylaxis is taken as prescribed. Since FDA (US Food and Drug Administration) approval of the first product for pre-exposure prophylaxis in 2012, uptake has been lower than the estimated 1.1 million US adults who could benefit from its use, with an estimated 70,394 individuals on pre-exposure prophylaxis in 2017. Of these, only 11% were Black and 13% were Hispanic despite Black and Hispanic individuals comprising two-thirds of individuals who could benefit, highlighting racial and ethnic disparities in pre-exposure prophylaxis uptake. Patient navigators have been shown to be effective in improving the linkage and retention in care outcomes of people living with HIV across the HIV treatment cascade and can be used throughout the pre-exposure prophylaxis care continuum to assist decision making and connect potential users to pre-exposure prophylaxis services.ObjectivePleasePrEPMe Chat was designed as a novel online strategy aimed at improving engagement in pre-exposure prophylaxis care services with pre-exposure prophylaxis–eligible populations in California via free HIV-prevention information and health care navigation services.MethodsVisitors connected with navigators via online bilingual (English, Spanish) chat. During the chat, navigators helped locate pre-exposure prophylaxis services through the PleasePrEPMe provider directory, provided links to HIV-prevention resources, and supported uninsured, insured, and undocumented visitors with benefits navigation. Data such as date, time, type of encounter, visitor type, key demographics, discussion topics, insurance, and other relevant information were collected via a chat log and through the HealthEngage chat platform.ResultsFrom April 2017 to December 2019, PleasePrEPMe completed 2191 online chats. Mean interaction time was 16 minutes, with 68% of chats covering more than one topic. Conversation topics included health care navigation (1104/2191, 50.39%), provider identification (954/2191, 43.54%), pre-exposure prophylaxis information (773/2191, 35.28%), post-exposure prophylaxis information (318/2191, 14.91%), and the California Pre-Exposure Prophylaxis Assistance Program (232/2191, 10.59%). Referrals to pre-exposure prophylaxis– or non pre-exposure prophylaxis–related resources included directory updates, HIV testing and treatment, undetectable=untransmittable, reproductive health, sexually transmitted infections, and other prevention methods. A total of 368 chat visitors completed a voluntary satisfaction scale rating the quality and helpfulness of the service provided, producing a mean rating of 4.7 out of 5.ConclusionsOnline chat is a method for reaching people not already engaged in HIV-prevention services, supporting HIV-prevention decision making, and linking people seeking information online with in-person services. Additional research to evaluate online sexual health information services and understand how social determinants of health influence online engagement is needed to better understand how to reach priority populations not well served by current HIV-prevention services.International Registered Report Identifier (IRRID)RR1-10.2196/20187

“I’m doing this test so I can benefit from PrEP”: exploring HIV testing barriers/facilitators and implementation of pre-exposure prophylaxis among South African adolescents

In South Africa, adolescents are a key population in the HIV epidemic that can benefit from increased access to oral pre-exposure prophylaxis (PrEP). HIV testing is an integral component of the PrEP care continuum but adolescents in South Africa have generally low HIV testing rates; therefore, adolescents’ HIV testing attitudes and behaviours must be understood to develop strategies for effective PrEP implementation. Ten focus groups were conducted with adolescents living with HIV and HIV-uninfected adolescents (n = 55), and in-depth interviews were conducted with service providers (n = 25), adolescents living with HIV (n = 10) and HIV-uninfected adolescents (n = 25). Data were collected in the Western Cape province of South Africa from 2015–2016. Thematic framework analysis was used to understand dynamics by which South African adolescents’ attitudes toward HIV testing might influence intended uptake of PrEP and, reciprocally, to explore the implications of adolescents’ perceptions about PrEP availability for their willingness to engage in HIV testing. While South African adolescents’ current HIV testing attitudes and behaviours present barriers to intended PrEP implementation in this population, increased access to PrEP has the potential to improve their initial HIV testing rates and decrease stigma and fear around HIV testing. However, implementation of PrEP must consider specific HIV testing barriers for adolescent boys and girls, respectively. As PrEP becomes more widely available for adolescents, possible challenges noted by participants may include the potential for adolescents to reduce continued HIV testing behaviours while on PrEP and to share/use unprescribed PrEP medications among peers.
