The DC Cohort is a longitudinal HIV cohort study of people with HIV receiving care at 14 clinical sites in Washington, DC, led by George Washington University. Data are routinely linked to the DC Department of Health (DC Health) HIV surveillance databases to increase data completeness and accuracy and to help identify people with HIV enrolled at multiple sites. The ATra Black Box (Black Box henceforth) is a novel privacy technology developed by Georgetown University, which is currently deployed in 40 public health jurisdictions. The Black Box provides a secure mechanism to link private health information across data systems. The Black Box was modified for the purposes of linking data from the DC Cohort to DC Health surveillance data and increasing the ease, feasibility, accuracy, and timeliness of future linkages. These modifications included providing deidentified data to George Washington University and developing analytic code to compare data between the DC Cohort and DC Health to report on data discrepancies. This paper reports on the results of the initial linkage using the Black Box. DC Cohort data on all consented participants from January 2011 through September 2022 were submitted to the Black Box. Simultaneously, all DC Health HIV surveillance data were also submitted to the Black Box. The data were matched using a predetermined algorithm, match-level scores were assigned, and matches were manually verified. The new Black Box graphical user interface allows users to check files for errors and easily track the Black Box processes and provides analytic plugins for running SAS code. A total of 9744 records of DC Cohort participants were submitted for matching to DC Health. Of these, 9060 participants (93.0%) matched to surveillance data and were validated through manual review. Match-level scores ranged from 20 to 100, and the validation found that scores of 61 and above were true matches. The SAS output files provided information on missing or conflicting data, including lab records, date of HIV diagnosis, and other key demographics. The linkage resulted in the addition of 48,970 CD4 T-lymphocyte counts, 33,413 viral load lab records, and 767 previously unrecognized deaths. Among the DC Cohort participants, 470 were enrolled at more than one site and 17 at more than two sites. The implementation of the Black Box for sharing DC Cohort and DC Health data resulted in better capture of HIV lab records, improved vital status information, and enhanced characterization of care patterns for people with HIV enrolled in the DC Cohort. Future linkages will include DC Health data on diagnoses of sexually transmitted infections, hepatitis, and tuberculosis.

People with HIV (PWH) are disproportionally affected by mpox and at risk of severe complications. We assessed mpox knowledge, adoption of preventive behaviors, and vaccination attitudes among PWH enrolled in a longitudinal HIV cohort in Washington, DC, the DC Cohort. We conducted uni- and multivariable analyses comparing participants by vaccination status and HIV risk group, and multinomial regression to identify factors associated with vaccine acceptance. Among 430 PWH, 378 (87.9%) were aware of mpox. Among 373 participants with vaccination status data, 101 (27.1%) were vaccinated, 129 (34.6%) planned to vaccinate, and 143 (38.3%) did not plan to vaccinate. The three vaccination groups differed significantly by age, race, education, HIV risk group, recent STI status, and level of mpox worry (all p < 0.05). A higher proportion of men who have sex with men (MSM) reported limiting their number of sexual partners compared to non-MSM (p < 0.0001). Multinomial regression models comparing vaccinated to unvaccinated PWH found age, education, mode of HIV transmission/gender, and survey period were significantly associated with vaccination status (all p < 0.05). High levels of mpox awareness were observed among this cohort of PWH with more MSM employing risk reduction behaviors and being vaccinated. Ensuring that PWH, regardless of gender, sexual orientation, or age, understand the risks of mpox may improve vaccination uptake.

Background: Transmasculine people are at risk for HIV; yet few HIV prevention interventions have been developed for this population. We adapted an existing HIV prevention smartphone app for cisgender men who have sex with men to meet the sexual health needs of transmasculine people. Objective: This study aims to assess the acceptability of the adapted app, Transpire, among transmasculine people living in Atlanta, Georgia, and Washington, DC, via in-depth interviews of participants in a pilot feasibility trial. Methods: Participants used the Transpire app for 3 months as part of a pilot study of the app. Eligible participants were aged 18-34 years. There were no eligibility criteria with respect to race and ethnicity, and most participants were non-Hispanic White. At the end of the follow-up, participants were invited to participate in web-based in-depth interviews to discuss their experiences using the app and feedback on design and content. Interviews were transcribed and coded using a constant comparative approach. Three main themes were identified: sexual behavior, app experiences and feedback, and pre-exposure prophylaxis. Results: Overall, participants found the app acceptable and thought that it would be a useful tool for themselves and their peers. Participants reported appreciating having a comprehensive information source available to them on their phones and reported learning more about HIV, sexually transmitted infections, and pre-exposure prophylaxis via the app. They also reported appreciating the inclusive language that was used throughout the app. Although the app included some resources on mental health and substance use, participants reported that they would have appreciated more resources and information in these areas as well as more comprehensive information about other health concerns, including hormone therapy. Representative quotes are presented for each of the identified themes. Conclusions: There is a desire to have greater access to reliable sexual health information among transmasculine people. Mobile apps like Transpire are an acceptable intervention to increase access to this information and other resources. More evidence is needed, however, from more racially and ethnically diverse samples of transmasculine people.

BACKGROUND Pre-exposure prophylaxis (PrEP) is an effective biomedical intervention with the potential to reduce HIV incidence. Despite this, PrEP uptake has been slow, especially among the groups at highest risk for acquiring HIV. Novel strategies are needed to improve PrEP awareness, access, uptake and adherence. The Emergency Department (ED) is a unique clinical setting that serves a substantial proportion of people at high-risk of HIV acquisition. Previous work suggests there may be an opportunity for the ED to increase PrEP uptake and improve linkage to HIV preventive care. In this study, we aim to determine the feasibility and acceptability of PrEP delivery in the ED in an urban setting. OBJECTIVE This project seeks to demonstrate the feasibility and acceptability of PrEP delivery in an ED in Washington, DC, an urban area with a high HIV prevalence rate. We will implement and assess the impact of our intervention with the goal of using this information to determine if the ED setting is an appropriate clinical setting to offer PrEP to patients at high risk of HIV acquisition. METHODS We will conduct a Hybrid Type I effectiveness-implementation study to simultaneously assess the effectiveness of PrEP screening and initiation in the ED as well as collect information to identify the barriers and facilitators of real-world implementation of this strategy for increasing PrEP uptake. We will screen and enroll ED patients with chief complaints or diagnostic tests ordered in the ED indicative of HIV risk. We will offer PrEP education, a 10-day starter pack of either TDF+FTC (Truvada) or TAF+ FTC (Descovy) and arrange a follow-up appointment with a community PrEP provider (CPP) to those who are determined to be PrEP eligible per CDC guidelines following the completion of a self-administered survey and applicable laboratory tests. For PrEP-eligible patients who decline to start PrEP in the ED, we will offer to arrange a referral visit to a CPP. Additionally, we will conduct surveys with study participants and in-depth interviews with participants, ED providers, CPPs, and research staff to identify factors that characterize best practices in implementation of ED PrEP and identify multi-level influencers to adoption of PrEP uptake. RESULTS The study was funded in March 2020, however; we did not initiate preparing for implementation until July 2021 due to the COVID-19 pandemic. The protocol was reviewed and approved by the George Washington University Institutional Review Board (NCR213868) on March 18, 2022. Enrollment began on December 1, 2022, and 35 study participants were enrolled when the study was terminated on May 10, 2023. CONCLUSIONS This study will offer some of the first data on ED-initiated PrEP uptake and adherence and provide insights into barriers and facilitators to PrEP uptake among patients seeking care in an ED in a high prevalence urban epidemic area. These data will guide our understanding of how best to implement PrEP delivery in ED settings.

Background: COVID-19 has not only taken a staggering toll in terms of cases and lives lost, but also in its psychosocial effects. We assessed the psychosocial impacts of the COVID-19 pandemic in a large cohort of people with HIV (PWH) in Washington DC and evaluated the association of various demographic and clinical characteristics with psychosocial impacts.Methods: From October 2020 to December 2021, DC Cohort participants were invited to complete a survey capturing psychosocial outcomes influenced by the COVID-19 pandemic. Some demographic variables were also collected in the survey, and survey results were matched to additional demographic data and laboratory data from the DC Cohort database. Data analyses included descriptive statistics and multivariable logistic regression models to evaluate the association between demographic and clinical characteristics and psychosocial impacts, assessed individually and in overarching categories (financial/employment, mental health, decreased social connection, and substance use).Results: Of 891 participants, the median age was 46 years old, 65% were male, and 76% were of non-Hispanic Black race/ethnicity. The most commonly reported psychosocial impact categories were mental health (78% of sample) and financial/employment (56% of sample). In our sample, older age was protective against all adverse psychosocial impacts. Additionally, those who were more educated reported fewer financial impacts but more mental health impacts, decreased social connection, and increased substance use. Males reported increased substance use compared with females.Conclusions: The COVID-19 pandemic has had substantial psychosocial impacts on PWH, and resiliency may have helped shield older adults from some of these effects. As the pandemic continues, measures to aid groups vulnerable to these psychosocial impacts are critical to help ensure continued success towards healthy living with HIV.

Pre-exposure prophylaxis (PrEP) for HIV is highly effective, yet uptake has been limited. We measured PrEP knowledge, eligibility, and referral willingness among patients receiving emergency or acute care in Washington, DC. We surveyed HIV-negative patients with STI-related complaints on HIV risk behaviors, PrEP knowledge, eligibility, and willingness for PrEP referral. Among 174 participants, 70% were PrEP unaware and 33% were PrEP eligible. Most participants (81%) supported learning more, 64% would consider taking PrEP, and 28% agreed to immediate referral. Willingness to learn more about PrEP suggests referral from non-traditional settings may increase uptake. Further evaluation of this approach is warranted.

Pre-exposure prophylaxis (PrEP) is an effective method to prevent HIV acquisition in high-risk individuals. This cross-sectional survey study estimated the proportion of patients who were PrEP eligible among a targeted sample of emergency department (ED) patients with chief complaints indicative of HIV risk. Research assistants screened a convenience sample of adult patients who presented to two hospital EDs in Washington, DC, during a 6-month period with genitourinary, substance use, or intentional injury-related complaints. Patients with these complaints who reported being sexually active within the past 6 months and HIV negative completed a computer-assisted survey that included questions on sexual practices and partners, substance use, and attitudes and knowledge about PrEP. We used the Centers for Disease Control and Prevention (CDC) clinical guidelines to determine whether PrEP use was indicated. We report differences in PrEP eligibility by demographic characteristics, knowledge, and attitudes. Of the 410 participants, the majority were black (85%), and heterosexual females (72%). PrEP use was indicated in 20% (N = 84), most commonly because of condomless sex with a person of unknown HIV status (82%) and/or a sexually transmitted infection (STI) diagnosis (41%). One-third (34%) of participants had heard of PrEP. Overall, 36% of the sample (N = 148) wanted to learn more about PrEP while in the ED. The percentage who wanted to learn more about PrEP was higher among PrEP-eligible patients (52%) compared with PrEP-ineligible patients (32%). Using CDC criteria, targeted screening identified that a substantial proportion of ED patients are PrEP eligible based on their self-reported behaviors.
