RESUMO

Over the past two decades, cases of sexually transmitted infections (STIs) due to syphilis, gonorrhea, and chlamydia have been rising in the United States, disproportionately among gay, bisexual, and other men who have sex with men (MSM), as well as racial and ethnic minorities of all genders. In this review, we address updates about the evidence on doxycycline post-exposure prophylaxis (doxy-PEP) for prevention of bacterial STIs, including efficacy, safety, antimicrobial resistance (AMR), acceptability, modeling population impact, and evolving guidelines for use. Equitable implementation of doxy-PEP will require evaluation of who is offered and initiates it, understanding patterns of use and longer-term STI incidence and AMR, provider training, and tailored community education.

RESUMO

BACKGROUND: Current guidelines recommend concurrent screening for HIV and syphilis with gonorrhea and chlamydia testing. Despite this, many patients are still not screened. This study describes trends in demographics and encounter locations associated with missed opportunities for HIV and syphilis screening among patients tested for gonorrhea or chlamydia. METHODS: This is a retrospective review of all encounters with gonorrhea or chlamydia testing in a large, urban hospital from November 1, 2018, to July 31, 2021. Demographic information and encounter location were extracted from the medical record. Encounters were categorized as including both HIV and syphilis (complete) screening, HIV screening only, or neither. Logistic regression was used to examine associations between demographics and encounter location and likelihood of complete screening. RESULTS: There were 42,791 patient encounters, of which 40.2% had complete screening, 6.2% had concurrent HIV screening only, and 53.6% had no concurrent screening. Increasing age, female sex (aOR 0.58, 95% CI 0.55-0.61, p < 0.01), non-Hispanic Black race (aOR 0.52, 95% CI 0.49-0.55, p < 0.01), and public insurance (aOR 0.72, 95% CI 0.69-0.75, p < 0.01) were associated with lower odds of complete screening. Emergency department (ED) encounters were most likely to include complete screening (aOR 3.11, 95% CI 2.96-3.26, p < 0.01). CONCLUSIONS: This study found a large proportion of patients tested for gonorrhea and chlamydia had missed opportunities for HIV and syphilis screening. Significant demographic disparities were found. The ED was most likely to screen for both HIV and syphilis. Decreasing disparities in screening could have profound effects on the HIV and syphilis epidemics.

RESUMO

Understanding the acceptability of long-acting injectable antiretroviral therapy (LAI-ART) among people with HIV (PWH), especially priority populations, is essential for effective implementation. We conducted semi-structured interviews with patients in three Ryan White-funded HIV clinics in San Francisco, Chicago, and Atlanta. We employed maximal variation sampling across age, gender, race, ethnicity, and time living with HIV and oversampled for individuals with suboptimal clinical engagement. An 8-step hybrid deductive and inductive thematic analysis approach guided data analysis. Between August 2020 and July 2021, we conducted 72 interviews. Median age was 46 years; 28% were ciswomen, 7% transwomen, 44% Black/African-American and 35% Latinx, 43% endorsed a psychiatric diagnosis, 35% were experiencing homelessness/unstable housing, and 10% had recent substance use. Approximately 24% were sub-optimally engaged in care. We observed a spectrum of LAI-ART acceptability, ranging from enthusiasm to hesitancy to rejection. We also characterized four emergent orientations towards LAI-ART: innovator, pragmatist, deliberator, and skeptic. Overall, the majority of participants expressed favorable initial reactions towards LAI-ART. Most approached LAI-ART pragmatically, but acceptability was not static, often increasing over the course of the interview. Participants considered their HIV providers as essential for affirming personal relevance. HIV stigma, privacy concerns, and medical mistrust had varied impacts, sometimes facilitating and other times hindering personal relevance. These findings held across priority populations, specifically young adults, cis/trans women, racial/ethnic minorities, and individuals with suboptimal clinical engagement. Further research is needed to explore the transition from hypothetical acceptance to uptake and to confirm the actual benefits and drawbacks of this treatment.


RESUMEN: La aceptabilidad de la terapia antirretroviral inyectable de acción prolongada (LAI-ART, por su sigla en inglés) entre personas con VIH es esencial para una implementación efectiva. Durante el periodo de agosto de 2020 a julio de 2021, realizamos 72 entrevistas semiestructuradas con personas con VIH en clínicas públicas ubicadas en San Francisco, Chicago y Atlanta. Un análisis temático, tanto deductivo como inductivo, guio nuestra investigación. Observamos un espectro de aceptabilidad de LAI-ART que va desde el entusiasmo hasta la indecisión y el rechazo. También caracterizamos cuatro orientaciones actitudinales emergentes hacia LAI-ART: innovadora, pragmática, deliberativa y escéptica. Los participantes también señalaron la importancia de sus proveedores de VIH para validar su relevancia personal. El estigma asociado al VIH, preocupaciones sobre la privacidad y desconfianza en el sistema médico tuvieron diversos impactos, a veces facilitando y otras veces obstaculizando la relevancia personal. Entre las poblaciones prioritarias del estudio, los resultados fueron consistentes.

RESUMO

Limited published data suggest rates of HIV may be high among trauma patients. This study compares rates of HIV screening and diagnosis among trauma and medical patients at a Level 1 trauma center emergency department (ED) with a universal HIV screening program. This is a retrospective cross-sectional study of all ED encounters from May 1, 2018, through May 1, 2021. Duplicate encounters, encounters with repeat testing within one year, and patients younger than 18 or older than 65 were excluded. Chi-squared analysis was used to compare demographics, rates of HIV testing, new and known HIV infections, and linkage to care between trauma and medical patients. After exclusion criteria were applied, 147,430 encounters from 91,468 unique patients were analyzed. Trauma comprised 7,497 (5.4%) encounters. Trauma patients were less likely to be screened for HIV than medical patients (18.1% vs 25.6%; OR 0.64; 95%CI, 0.61-0.68, p < .01). Trauma patients had higher rates of HIV (2.2% vs 1.3%; OR 1.78; 95% CI, 1.22-2.58, p < .01). Both trauma and medical patients would benefit from strategies to increase screening. Including trauma patients in routine ED HIV screening should be a priority to increase diagnosis rate and linkage to care in key populations.

RESUMO

Due to improved efficiency and reduced cost of viral sequencing, molecular cluster analysis can be feasibly utilized alongside existing human immunodeficiency virus (HIV) prevention strategies. The goal of this paper is to elucidate how HIV molecular cluster and social network analyses are being integrated to implement HIV response interventions. We searched PubMed, Scopus, PsycINFO, and Cochrane Library databases for studies incorporating both HIV molecular cluster and social network data. We identified 32 articles that combined analyses of HIV molecular sequences and social or sexual networks. All studies were descriptive. Six studies described network interventions informed by molecular and social data but did not fully evaluate their efficacy. There is no current standard for incorporating molecular and social network analyses to inform interventions or data demonstrating its utility. More research must be conducted to delineate benefits and best practices for leveraging molecular data for network-based interventions.


RESUMEN: Debido a mejor eficiencia y costo reducido de la secuenciación viral, el análisis de complejos moleculares se puede utilizar de manera factible junto con las estrategias de prevención del virus de inmunodeficiencia humana (VIH) existentes. El objetivo de este repaso es de aclarar como integrar los análisis de las redes sociales y de los complejos moleculares del VIH para implementar intervenciones para controlar el VIH. Buscamos en las bases de datos de PubMed, Scopus, PsycINFO y Cochrane Library por estudios que incorporaran datos de redes sociales y grupos moleculares del VIH. Identificamos 32 estudios que combinaban análisis de secuencias moleculares del VIH y datos de redes sociales. Todos los estudios fueron descriptivos. Seis estudios describieron intervenciones informadas por datos moleculares y sociales, pero no evaluaron completamente su eficacia. No existe un estándar actual para incorporar análisis moleculares y sociales para informar intervenciones o datos que demuestren su eficacia. Se deben realizar más investigaciones para delinear los beneficios y las mejores prácticas de aplicar los datos moleculares y sociales para crear intervenciones del VIH.

RESUMO

COVID-19 has disrupted routine medical care and increased psychosocial and economic stressors on a global scale, yet the full impact on people living with HIV (PLWH) and the HIV continuum of care remains unknown. As the pandemic continues to pose a significant threat to PLWH and their care, this research qualitatively aimed to elicit COVID-19-related challenges and perspectives of PLWH during the early phase of the pandemic and to identify lessons learned and impactful strategies for facilitating HIV care. We recruited 32 PLWH who receive care at a large academic medical center for semi-structured remote interviews to assess psychological/structural stressors experienced during the pandemic and to discern strategies for improving care. Most participants identified as Black (91%) and heterosexual (56%). Overall, PLWH reported exacerbated mental health stressors (e.g., anxiety, depression, substance use). Most participants cited no issues with antiretroviral therapy (ART) adherence or retention in care, yet five participants reported appointment cancellations or physician inaccessibility. Participants provided specific feedback for facilitating continued engagement in care during the pandemic, including telemedicine and education/patient empowerment. By seeking participant-provided solutions, this study centered on PLWH's experiences and emphasized proactive HIV care strategies for prioritizing patient empowerment and healthcare adaptability during a rapidly evolving pandemic.

RESUMO

BACKGROUND: The COVID-19 pandemic has affected the health and well-being of people worldwide, yet few studies have qualitatively examined its cumulative effects on ciswomen living with HIV (WLWH). We aimed to explore how the pandemic has impacted WLWH, including challenges related to HIV care, employment, finances, and childcare. We also investigated how HIV status and different psychosocial stressors affected their mental health. METHODS: We performed 25 semi-structured qualitative interviews with WLWH regarding the ways in which COVID-19 impacted their social determinants of health and physical well-being during the pandemic. 19 WLWH who received care at the University of Chicago Medicine (UCM) and 6 women who received care at Howard Brown Health, a federally qualified health center (FQHC) in Chicago, were interviewed remotely from June 2020 to April 2021. All interviews were audio recorded and transcribed. Interviews were thematically analyzed for commonalities regarding HIV-specific and general experiences of WLWH during the pandemic. RESULTS: The majority of participants reported COVID-19 impacted their HIV care, such as appointment cancellations and difficulties adhering to antiretroviral therapy. In addition to HIV care obstacles, almost all participants described perceived heightened vulnerability to or fear of COVID-19. The pandemic also affected the socioeconomic well-being of participants, with reported financial strains and employment disruptions. Some mothers took on additional childcare responsibilities, such as homeschooling. Increased mental health concerns and negative psychological effects from the social isolation associated with the pandemic were also experienced by most participants. CONCLUSIONS: We gained invaluable insight into how WLWH were challenged by and adapted to the COVID-19 pandemic, including its destabilizing effects on their HIV care and mental health. Women described how they undertook additional childcare responsibilities during the pandemic and how their HIV status compounded their concerns (e.g., perceived heightened vulnerability to COVID-19). Strategies to better support WLWH in maintaining their overall health throughout the pandemic include childcare assistance, access to affordable mental health services, support groups, and education from HIV care providers. These findings have significant implications for examining future health crises through the perspective of potential gender inequalities.

RESUMO

Shared decision making is a collaborative process intended to develop a treatment plan that considers both the patient's preferences and the health provider's medical recommendations. It is one approach to reducing healthcare disparities by improving patient-provider communication and subsequent health outcomes. This study examines shared decision making about HIV pre-exposure prophylaxis (PrEP) with Black transgender women in Chicago, Illinois, USA, given high prevalence of HIV and disparities in PrEP use. Black transgender women were recruited online and in-person to participate in semi-structured interviews (n = 24) and focus groups (2; n = 14 total), conducted between 2016 and 2017. Iterative thematic content analysis took place. Analysis revealed that internalised transphobia and racism, combined with stigma from service providers, prevented disclosure of gender and sexual identity to providers. Stigma about PrEP as it relates to Black transgender women results in stereotype threat, which undermines patient-provider trust and deters shared decision making for PrEP. Shared decision making promotes cultural competence and humility and builds trust within the patient-provider relationship, leading to better communication and less stigma. The involvement of peers may be one way to mitigate stigma for Black transgender women around PrEP, promote cultural competence within organisations, and empower engagement in shared decision making for HIV prevention.

RESUMO

Offering people living with HIV the opportunity to refer partners for HIV testing is an efficient way of identifying new HIV diagnoses. This report describes the outcomes of physician-led partner services at an urban academic center. Patients with HIV VL > 1000 copies/mL in both inpatient and outpatient settings were offered partner notification services (PNS). Of referred partners, 8.7% had a new diagnosis of HIV. New HIV+ partners were as likely to be referred by patients with existing HIV diagnoses as new diagnoses (p = 0.61), and as likely to be referred by patients interviewed while hospitalized as those in the clinic (p = 0.61).

RESUMO

BACKGROUND: The COVID-19 and HIV epidemics have exacerbated existing inequities among vulnerable groups and severely impacted communities of color. People living with HIV (PLWH), who may already face stigma or discrimination, are at risk of experiencing further stigma as a result of COVID-19, which can result in medical mistrust. METHODS: We performed qualitative interviews between June and August 2020 among 32 PLWH, including 10 individuals diagnosed with COVID-19. A majority of participants perceived themselves as having an increased risk of contracting COVID-19 due to their HIV status. RESULTS: Of those who tested positive for COVID-19, the majority regarded their HIV diagnosis as having a more profound impact on their lives but found similarities between COVID-19 stigma and HIV-related stigma. Many participants also expressed mistrust. CONCLUSIONS: These results can be used to better understand the perspectives of PLWH during the COVID-19 pandemic and have important implications for potential COVID-19 vaccine hesitancy and future health crises.

RESUMO

In 2019, the requisite biomedical and behavioral interventions to eliminate new HIV infections exist. "Ending the HIV Epidemic" now becomes primarily a challenge of will and implementation. This review maps the extent to which implementation research (IR) has been integrated into HIV research by reviewing the recent funding portfolio of the NIH. We searched NIH RePORTER for HIV and IR-related research projects funded from January 2013 to March 2018. The 4629 unique studies identified were screened using machine learning and manual methods. 216 abstracts met the eligibility criteria of HIV and IR. Key study characteristics were then abstracted. NIH currently funds HIV studies that are either formally IR (n = 109) or preparatory for IR (n = 107). Few (13%) projects mentioned a guiding implementation model, theory, or framework, and only 56% of all studies explicitly mentioned measuring an implementation outcome. Considering the study aims along an IR continuum, 18 (8%) studies examined barriers and facilitators, 43 (20%) developed implementation strategies, 46 (21%) piloted strategies, 73 (34%) tested a single strategy, and 35 (16%) compared strategies. A higher proportion of formal IR projects involved established interventions (e.g., integrated services) compared to newer interventions (e.g., pre-exposure prophylaxis). Prioritizing HIV-related IR in NIH and other federal funding opportunity announcements and expanded training in implementation science could have a substantial impact on ending the HIV pandemic. This review serves as a baseline by which to compare funding patterns and the sophistication of IR in HIV research over time.

RESUMO

BACKGROUND: Young people account for more than a quarter of new HIV infections in the US, with the majority of cases among young men who have sex with men; young transgender women are also vulnerable to infection. Substance use, particularly alcohol misuse, is a driver of sexual transmission and a potential barrier to engagement in the HIV prevention and care continuum, however vulnerable youth are difficult to reach for substance use services due, in part, to complex social and structural factors and limited access to health care. The Community Prevention Services Task Force recommends electronic screening and brief intervention as an evidence-based intervention for the prevention of excessive alcohol consumption; however, no prior studies have extended this model to community-based populations of youth that are susceptible to HIV infection. This paper describes the study protocol for an electronic screening and brief intervention to reduce alcohol misuse among adolescents and young adults vulnerable to HIV infection in community-based settings. METHODS: This study, Step Up, Test Up, is a randomized controlled trial of an electronic alcohol screening and brief intervention among youth, ages 16-25, who are vulnerable to HIV infection. Individuals who present for HIV testing at one of three community-based locations are recruited for study participation. Eligibility includes those aged 16-25 years, HIV-negative or unknown HIV status, male or trans female with a history of sex with men, and English-speaking. Participants who screen at moderate to high risk for alcohol misuse on the Alcohol Use Disorders Identification Test (AUDIT) are randomized (1:1) to either an electronic brief intervention to reduce alcohol misuse or a time-and attention-matched control. The primary outcome is change in the frequency/quantity of recent alcohol use at 1, 3, 6 and 12-month follow-up. DISCUSSION: Testing of evidence-based interventions to reduce alcohol misuse among youth vulnerable to HIV infection are needed. This study will provide evidence to determine feasibility and efficacy of a brief electronically-delivered intervention to reduce alcohol misuse for this population. TRIAL REGISTRATION: ClinicalTrials.gov number, NCT02703116, registered March 9, 2016.

RESUMO

Shared decision-making is a strategy to achieve health equity by strengthening patient-provider relationships and improve health outcomes. There is a paucity of research examining these factors among patients who identify as sexual or gender minorities and racial/ethnic minorities. Through intrapersonal, interpersonal and societal lenses, this project evaluates the relationship between intersectionality and shared decision-making around anal cancer screening in Black gay and bisexual men, given their disproportionate rates of anal cancer. Thirty semi-structured, one-on-one interviews and two focus groups were conducted during 2016-2017. Participants were asked open-ended questions regarding intersectionality, relationships with healthcare providers and making shared decisions about anal cancer screening. Forty-five individuals participated - 30 in individual interviews and 15 in focus groups. All participants identified as Black and male; 13 identified as bisexual and 32 as gay. Analysis revealed that the interaction of internalised racism, biphobia/homophobia, provider bias and medical apartheid led to reduced healthcare engagement and discomfort with discussing sexual practices, potentially hindering patients from engaging in shared decision-making. Non-judgemental healthcare settings and provider relationships in which patients communicate openly about each aspect of their identity will promote effective shared decision-making about anal cancer screening, and thus potentially impact downstream anal cancer rates.

RESUMO

BACKGROUND: USA300 methicillin-resistant Staphylococcus aureus (MRSA) is a community- and hospital-acquired pathogen that frequently causes infections but also can survive on the human body asymptomatically as a part of the normal microbiota. We devised a comparative genomic strategy to track colonizing USA300 at different body sites after an initial infection. We sampled ST8 S. aureus from subjects at the site of a first known MRSA infection. Within 60 days of this infection and again 12 months later, each subject was tested for asymptomatic colonization in the nose, throat and perirectal region. 93 S. aureus strains underwent whole genome shotgun sequencing. RESULTS: Among 28 subjects at the initial sampling time, we isolated S. aureus from the nose, throat and perirectal sites from 15, 11 and 15 of them, respectively. Twelve months later we isolated S. aureus from 9 subjects, with 6, 3 and 3 strains from the nose, throat and perirectal area, respectively. Genome sequencing revealed that 23 patients (ages 0-66 years) carried USA300 intra-subject lineages (ISLs), defined as having an index infection isolate and closely related colonizing strains. Pairwise distance between strains in different ISLs was 48 to 162 single nucleotide polymorphisms (SNPs) across the core regions of the chromosome, whereas within the same ISL it was 0 to 26 SNPs. Strains in ISLs from the same subject differed in plasmid and prophage content, and contained deletions that removed the mecA-containing SCCmec and ACME regions. Five strains contained frameshift mutations in agr toxin-regulating genes. Persistence of an ISL was not associated with clinical or demographic subject characteristics. We inferred that colonization with the ISL occurred about 18 weeks before the first assessment of asymptomatic colonization. CONCLUSIONS: Clonal lineages of USA300 may continue to colonize people at one or more anatomic sites up to a year after an initial infection and experience loss of the SCCmec, loss and gain of other mobile genetic elements, and mutations in the agr operon.

RESUMO

BACKGROUND: Enhancing patient-centered care and shared decision making (SDM) has become a national priority as a means of engaging patients in their care, improving treatment adherence, and enhancing health outcomes. Relatively little is known about the healthcare experiences or shared decision making among racial/ethnic minorities who also identify as being LGBT. The purpose of this paper is to understand how race, sexual orientation and gender identity can simultaneously influence SDM among African-American LGBT persons, and to propose a model of SDM between such patients and their healthcare providers. METHODS: We reviewed key constructs necessary for understanding SDM among African-American LGBT persons, which guided our systematic literature review. Eligible studies for the review included English-language studies of adults (≥ 19 y/o) in North America, with a focus on LGBT persons who were African-American/black (i.e., > 50 % of the study population) or included sub-analyses by sexual orientation/gender identity and race. We searched PubMed, CINAHL, ProQuest Dissertations & Theses, PsycINFO, and Scopus databases using MESH terms and keywords related to shared decision making, communication quality (e.g., trust, bias), African-Americans, and LGBT persons. Additional references were identified by manual reviews of peer-reviewed journals' tables of contents and key papers' references. RESULTS: We identified 2298 abstracts, three of which met the inclusion criteria. Of the included studies, one was cross-sectional and two were qualitative; one study involved transgender women (91 % minorities, 65 % of whom were African-Americans), and two involved African-American men who have sex with men (MSM). All of the studies focused on HIV infection. Sexual orientation and gender identity were patient-reported factors that negatively impacted patient/provider relationships and SDM. Engaging in SDM helped some patients overcome normative beliefs about clinical encounters. In this paper, we present a conceptual model for understanding SDM in African-American LGBT persons, wherein multiple systems of social stratification (e.g., race, gender, sexual orientation) influence patient and provider perceptions, behaviors, and shared decision making. DISCUSSION: Few studies exist that explore SDM among African-American LGBT persons, and no interventions were identified in our systematic review. Thus, we are unable to draw conclusions about the effect size of SDM among this population on health outcomes. Qualitative work suggests that race, sexual orientation and gender work collectively to enhance perceptions of discrimination and decrease SDM among African-American LGBT persons. More research is needed to obtain a comprehensive understanding of shared decision making and subsequent health outcomes among African-Americans along the entire spectrum of gender and sexual orientation.

RESUMO

BACKGROUND: Skin and soft tissue infections (SSTIs) are common in the era of community-associated methicillin resistant Staphylococcus aureus among HIV-infected patients. Recurrent infections are frequent. Risk factors for recurrence after an initial SSTI have not been well-studied. METHODS: Retrospective cohort study, single center, 2005-2009. Paper and electronic medical records were reviewed by one of several physicians. Subjects with initial SSTI were followed until the time of SSTI recurrence. Standard descriptive statistics were calculated to describe the characteristics of subjects who did and did not develop a recurrent SSTI. Kaplan-Meier methods were used to estimate the risk of recurrent SSTI. A Cox regression model was developed to identify predictors of SSTI recurrence. RESULTS: 133 SSTIs occurred in 87 individuals. 85 subjects were followed after their initial SSTI, of whom 30 (35.3 %) had a recurrent SSTI in 118.3 person-years of follow-up, for an incidence of second SSTI of 253.6 SSTIs/1000 person-years (95 % CI 166.8-385.7). The 1-year Kaplan-Meier estimated risk of a second SSTI was 29.2 % (95 % CI 20.3-41.0 %), while the 3-year risk was 47.0 % (95 % CI 34.4-61.6 %). Risk factors for recurrent SSTI in a multivariable Cox regression model were non-hepatitis liver disease (HR 3.44; 95 % CI 1.02-11.5; p = 0.05), the presence of an intravenous catheter (HR 6.50; 95 % CI 1.47-28.7; p = 0.01), and a history of intravenous drug use (IVDU) (HR 2.80; 95 % CI 1.02-7.65; p = 0.05); African-American race was associated with decreased risk of recurrent SSTI (HR 0.12; 95 % CI 0.04-0.41; p < 0.01). Some evidence was present for HIV viral load ≥ 1000 copies/mL as an independent risk factor for recurrent SSTI (HR 2.21; 95 % CI 0.99-4.94; p = 0.05). Hemodialysis, currently taking HAART, CD4+ count, trimethoprim-sulfamethoxazole or azithromycin use, initial SSTI type, diabetes mellitus, incision and drainage of the original SSTI, or self-report of being a man who has sex with men were not associated with recurrence. CONCLUSION: Of HIV-infected patients with an SSTI, nearly 1/3 had a recurrent SSTI within 1 year. Risk factors for recurrent SSTI were non-hepatitis liver disease, intravenous catheter presence, a history of IVDU, and non-African-American race. Low CD4+ count was not a significant risk factor for recurrence.

RESUMO

BACKGROUND: There is increasing interest in improving routine HIV screening in emergency departments and increasing HIV cotesting rates among patients tested for sexually transmitted infections (STIs), who are considered at elevated risk of acquiring HIV. METHODS: This is a retrospective review of all ED encounters at a large, urban emergency departments with an existing HIV screening program for seven months before (November 1, 2018, to May 30, 2019) and after (June 1 to December 31, 2019) the implementation of a best practice advisory prompting universal HIV and syphilis screening. RESULTS: The study included 14,767 unique encounters, with 3,982 pre-implementation encounters and 10,785 post-implementation. After implementation, HIV testing increased 242%, from 2,851 tests to 9,757, and syphilis testing increased 326%, from 2,191 tests to 9,330. The proportion of encounters for urogenital STI testing without HIV cotesting decreased by 10.3%, from 43.6% to 33.3%. DISCUSSION: An automated electronic medical record (EMR) prompt can have a huge impact on both HIV and syphilis testing rates, as well as the rate of missed opportunities for cotesting among patients undergoing STI testing. CONCLUSIONS: Hospitals should support screening with automated alerts to help meet quality metrics, improve screening rates, and reduce missed opportunities for screening in vulnerable patients.
