RESUMEN

Hepatitis C virus (HCV) elimination is an important global public health goal. However, the United States (US) is not on track to meet the World Health Organization's 2030 targets for HCV elimination. Recently, the White House proposed an HCV elimination plan that includes point-of-care (POC) HCV RNA testing, which is currently in use in many countries, but is not approved in the US. POC HCV RNA testing is crucial for implementing community-based testing, and for enabling test-and-treat programs, assessing cure, and monitoring for reinfection.. In this commentary, we review the status of POC HCV RNA testing in the US, discuss factors that are needed for successful implementation, and issue specific public health and policy recommendations that would allow for the use of POC HCV RNA testing to support HCV elimination.

RESUMEN

BACKGROUND: US overdose deaths have reached a record high. Syringe services programs (SSPs) play a critical role in addressing this crisis by providing multiple services to people who use drugs (PWUD) that help prevent overdose death. This study examined the perspectives of leadership and staff from a geographically diverse sample of US SSPs on factors contributing to the overdose surge, their organization's response, and ongoing barriers to preventing overdose death. METHODS: From 2/11/2021 to 4/23/2021, we conducted semi-structured interviews with leadership and staff from 27 SSPs sampled from the North American Syringe Exchange Network directory. Interviews were transcribed and qualitatively analyzed using a Rapid Assessment Process. RESULTS: Respondents reported that increased intentional and unintentional fentanyl use (both alone and combined with other substances) was a major driver of the overdose surge. They also described how the COVID-19 pandemic increased solitary drug use and led to abrupt increases in use due to life disruptions and worsened mental health among PWUD. In response to this surge, SSPs have increased naloxone distribution, including providing more doses per person and expanding distribution to people using non-opioid drugs. They are also adapting overdose prevention education to increase awareness of fentanyl risks, including for people using non-opioid drugs. Some are distributing fentanyl test strips, though a few respondents expressed doubts about strips' effectiveness in reducing overdose harms. Some SSPs are expanding education and naloxone training/distribution in the broader community, beyond PWUD and their friends/family. Respondents described several ongoing barriers to preventing overdose death, including not reaching certain groups at risk of overdose (PWUD who do not inject, PWUD experiencing homelessness, and PWUD of color), an inconsistent naloxone supply and lack of access to intranasal naloxone in particular, inadequate funding, underestimates of overdoses, legal/policy barriers, and community stigma. CONCLUSIONS: SSPs remain essential in preventing overdose deaths amid record numbers likely driven by increased fentanyl use and COVID-19-related impacts. These findings can inform efforts to support SSPs in this work. In the face of ongoing barriers, support for SSPs-including increased resources, political support, and community partnership-is urgently needed to address the worsening overdose crisis.

RESUMEN

Background Medications for Opioid Use Disorder (MOUD) are associated with important public health benefits. Program changes implemented in response to COVID-19 hold promise as ongoing strategies to improve MOUD treatment. Methods: MOUD patients on buprenorphine or methadone, providers, government regulators, and persons who use drugs not in MOUD were recruited in the Northeast region of the United States between June and October of 2020 via advertisements, fliers, and word of mouth. Semi-structured qualitative interviews were conducted. Interviews were professionally transcribed and thematically coded by two independent coders. Results: We conducted interviews with 13 people currently on buprenorphine, 11 currently on methadone, 3 previously on buprenorphine, 4 previously on methadone, and 6 who used drugs but had never been on MOUD. In addition, we interviewed MOUD providers, clinic staff, and government officials at agencies that regulate MOUD. Most participants found increased take-home doses, home medication delivery, and telehealth implemented during COVID-19 to be favorable, reporting that these program changes reduced travel time to clinics, facilitated retention in care, and reduced stigma associated with clinic attendance. However, some participants reported negative consequences of COVID-19, most notably, decreased access to basic resources, such as food, clothing, and harm reduction materials that had previously been distributed at some MOUD clinics. Conclusion: Access to and retention in MOUD can be lifesaving for persons using drugs. COVID-19-impelled program changes, including increased take-home doses, home medication delivery, and telehealth generally improved participants' experiences with MOUD. Making these permanent could improve retention in care.

RESUMEN

Evidence regarding the important role of adolescents and young adults (AYA) in accelerating and sustaining coronavirus disease 2019 (COVID-19) outbreaks is growing. Furthermore, data suggest that 2 known factors that contribute to high severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmissibility-presymptomatic transmission and asymptomatic case presentations-may be amplified in AYA. However, AYA have not been prioritized as a key population in the public health response to the COVID-19 pandemic. Policy decisions that limit public health attention to AYA and are driven by the assumption of insignificant forward transmission from AYA pose a risk of inadvertent reinvigoration of local transmission dynamics. In this viewpoint, we highlight evidence regarding the increased potential of AYA to transmit SARS-CoV-2 that, to date, has received little attention, discuss adolescent and young adult-specific considerations for future COVID-19 control measures, and provide applied programmatic suggestions.

RESUMEN

BACKGROUND: Methadone Maintenance Treatment (MMT) is widely recognized as one of the most effective ways of reducing risk of overdose, arrest, and transmission of blood-borne viruses like HIV and HCV among people that use opioids. Yet, MMT's use of restrictive take-home dose policies that force most patients to attend their clinic on a daily, or near-daily, basis may be unpopular with many patients and lead to low rates of treatment uptake and retention. In response, this article examines how clinics' take-home dosing policies have affected patients' experiences of treatment and lives in general. METHODS: This article is based on semi-structured, qualitative interviews with a variety of stakeholders in MMT. Interviews explored: reasons for engaging with, or not engaging with MMT; how MMT is conceptualized by patients and treatment providers (e.g., as harm reduction or route to abstinence and/or recovery); experiences with MMT; perception of barriers to MMT (e.g., organizational/regulatory, social) and how MMT might be improved to support peoples' substance use treatment needs and goals. RESULTS: Nearly all of the patients with past or present MMT use were highly critical of the limited access to take-home doses and consequent need for daily or near daily clinic attendance. Participants described how the use of restrictive take-home dose policies negatively impacted their ability to meet day-to-day responsibilities and also cited the need for daily attendance as a reason for quitting or avoiding OAT. Responses also demonstrate how such policies contribute to an environment of cruelty and stigma within many clinics that exposes this already-stigmatized population to additional trauma. CONCLUSIONS: Take-home dose policies in MMT are not working for a substantial number of patients and are reasonably seen by participants as degrading and dehumanizing. Revision of MMT regulations and policies regarding take home doses are essential to improve patient satisfaction and the quality and effectiveness of MMT as a key evidence-based treatment and harm reduction strategy.

RESUMEN

Introduction/Objectives: The incidence of hepatitis C (HCV) infection is rising among people who inject drugs (PWID). Even in the context of known HCV prevention and treatment strategies, some PWID remain unengaged in HCV care. This study aimed to identify and characterize experiences and perceptions of PWID regarding the acceptability and effectiveness of HCV testing and treatment at a local syringe service program (SSP). Methods: A total of 36 PWID participated in semi-structured interviews at an SSP in New York City. Interviews were audio-recorded, transcribed, and coded by three coders, following a constructivist grounded theory approach. Relevant themes were identified as they emerged from the data. Results: Interviews with PWID revealed three themes related to the impact of SSPs on HCV care: (1) non-stigmatizing SSP environments, (2) the role of SSPs in improving HCV knowledge, and (3) acceptability of SSPs as sites for HCV care among PWID. Discussion: This paper contributes to the ongoing understanding that SSPs provide a well-accepted source of HCV services for PWID. Participants believed that SSPs are accessible and effective sites for HCV care, and suggested that stigma among PWID continues to affect receipt of HCV care in traditional settings. Conclusions: Understanding attitudes and beliefs of PWID regarding the effectiveness of SSPs as sites for HCV care is crucial for the development of focused strategies to reduce HCV transmission, and to ultimately achieve HCV elimination. Given this, further research is warranted investigating how best to improve HCV care at harm reduction sites such as SSPs.

RESUMEN

BACKGROUND: Hepatitis C virus (HCV) remains endemic among people who use drugs (PWUD). Measures of HCV community viral load (CVL) and HCV care continuum outcomes may be valuable for ascertaining unmet treatment need and for HCV surveillance and control. METHODS: Data from patients in an opioid treatment program during 2013-2016 were used to (1) identify proportions of antibody and viral load (VL) tested, linked-to-care, and treated, in 2013-2014 and 2015-2016, and pre- and postimplementation of qualitative reflex VL testing; (2) calculate engaged-in-care HCV CVL and "documented" and "estimated" unmet treatment need; and (3) examine factors associated with linkage-to-HCV-care. RESULTS: Among 11 267 patients, proportions of HCV antibody tested (52.5% in 2013-2014 vs 73.3% in 2015-2016), linked-to-HCV-care (15.7% vs 51.8%), and treated (12.0% vs 44.7%) all increased significantly. Hispanic ethnicity was associated with less linkage-to-care, and Manhattan residence was associated with improved linkage-to-care. The overall engaged-in-care HCV CVL was 4 351 079 copies/mL (standard deviation = 7 149 888); local HCV CVLs varied by subgroup and geography. Documented and estimated unmet treatment need decreased but remained high. CONCLUSIONS: After qualitative reflex VL testing was implemented, care continuum outcomes improved, but gaps remained. High rates of unmet treatment need suggest that control of the HCV epidemic among PWUD will require expansion of HCV treatment coverage.

RESUMEN

BACKGROUND: Hepatitis C virus (HCV) incidence has increased in the worsening opioid epidemic. We examined the HCV preventive efficacy of medication-assisted treatment (MAT), and geographic variation in HCV community viral load (CVL) and its association with HCV incidence. METHODS: HCV incidence was directly measured in an open cohort of patients in a MAT program in New York City between 1 January 2013 and 31 December 2016. Area-level HCV CVL was calculated. Associations of individual-level factors, and of HCV CVL, with HCV incidence were examined in separate analyses. RESULTS: Among 8352 patients, HCV prevalence was 48.7%. Among 2535 patients seronegative at first antibody test, HCV incidence was 2.25/100 person-years of observation (PYO). Incidence was 6.70/100 PYO among those reporting main drug use by injection. Female gender, drug injection, and lower MAT retention were significantly associated with higher incidence rate ratios. Female gender, drug injection, and methadone doses <60 mg were independently associated with shorter time to HCV seroconversion. HCV CVLs varied significantly by geographic area. CONCLUSIONS: HCV incidence was higher among those with lower MAT retention and was lower among those receiving higher methadone doses, suggesting the need to ensure high MAT retention, adequate doses, and increased HCV prevention and treatment engagement. HCV CVLs vary geographically and merit further study as predictors of HCV incidence.

RESUMEN

BACKGROUND: The overlapping human immunodeficiency virus (HIV) and hepatitis C virus (HCV) epidemics disproportionately affect people with substance use disorders. However, many people who use substances remain unaware of their infection(s). OBJECTIVE: The objective of this study was to examine the efficacy of an on-site bundled rapid HIV and HCV testing strategy in increasing receipt of both HIV and HCV test results. RESEARCH DESIGN: Two-armed randomized controlled trial in substance use disorder treatment programs (SUDTP) in New York City. Participants in the treatment arm were offered bundled rapid HIV and HCV tests with immediate results on-site. Participants in the control arm were offered the standard of care, that is, referrals to on-site or off-site laboratory-based HIV and HCV testing with delayed results. PARTICIPANTS: A total of 162 clients with unknown or negative HIV and HCV status. MEASURES: The primary outcome was the percentage of participants with self-reported receipt of HIV and HCV test results at 1-month postrandomization. RESULTS: Over half of participants were Hispanic (51.2%), with 25.3% being non-Hispanic black and 17.9% non-Hispanic white. Two thirds were male, and 54.9% reported injection as method of drug use. One hundred thirty-four participants (82.7%) completed the 1-month assessment. Participants in the treatment arm were more likely to report having received both test results than those in the control arm (69% vs. 19%, P<0.001). Seven participants in the treatment arm received a preliminary new HCV diagnosis, versus 1 in the control arm (P=0.029). CONCLUSION: Offering bundled rapid HIV and HCV testing with immediate results on-site in SUDTPs may increase awareness of HIV and HCV infection among people with substance use disorders.

RESUMEN

BACKGROUND: Critically ill patients with coronavirus disease-2019 (COVID-19) are at the theoretical risk of invasive pulmonary aspergillosis (IPA) due to known risk factors. PATIENTS/METHODS: We aimed to describe the clinical features of COVID-19-associated pulmonary aspergillosis at a single centre in New York City. We performed a retrospective chart review of all patients with COVID-19 with Aspergillus isolated from respiratory cultures. RESULTS: A total of seven patients with COVID-19 who had one or more positive respiratory cultures for Aspergillus fumigatus were identified, all of whom were mechanically ventilated in the ICU. Four patients were classified as putative IPA. The median age was 79 years, and all patients were male. The patients had been mechanically ventilated for a mean of 6.8 days (range: 1-14 days) before Aspergillus isolation. Serum galactomannan level was positive for only one patient. The majority of our cases received much higher doses of glucocorticoids than the dosage with a proven mortality benefit. All four patients died. CONCLUSIONS: Vigilance for secondary fungal infections will be needed to reduce adverse outcomes in critically ill patients with COVID-19.

RESUMEN

PURPOSE OF REVIEW: This article reviews the case for recognizing (1) the epidemics of opioid misuse, overdose, hepatitis C virus, and HIV as a syndemic and (2) the importance of examining and addressing structural factors in responses to this syndemic. We focus on the current syndemic in the US, but also consider data from other locations to highlight the issues existing and arising in various contexts. RECENT FINDINGS: Advances in multi-level theory and statistical methods allow sound ecologic and multi-level analyses of the impact of structural factors on the syndemic. Studies of opioid misuse, overdoses, hepatitis C virus, and HIV demonstrate that area-level access to healthcare, medication-assisted treatment of opioid use disorders, sterile injection equipment, and overdose prevention with naloxone, as well as factors such as opioid marketing, income inequality, intensity of policing activities, and health care policies, are related to the prevalence of substance misuse, overdoses, infection risk, and morbidity. Structural variables can predict area-level vulnerability to the syndemic. The implementation of combined prevention and treatment interventions can control and reverse components of the syndemic. Recognizing and monitoring potent structural factors can facilitate the identification of areas at risk of vulnerability to the syndemic. Further, many structural factors are modifiable through intervention and policy to reduce structural vulnerability and create health-enabling environments. Evidence supports the immediate implementation of broader HCV and HIV testing and substance use screening, medication-assisted treatment, needle/syringe exchange programs, naloxone programs, increased population-level implementation of HCV treatment, and further attention to structural-level factors predicting, and contributing to, area-level vulnerability, such as degrees of opioid marketing, distribution, and prescribing.

RESUMEN

BACKGROUND: Herpes simplex virus type 2 (HSV-2) infection increases both susceptibility to and transmissibility of human immunodeficiency virus (HIV), and HSV-2 and HIV are often strongly associated in HIV epidemics. We assessed trends in HSV-2 prevalence among non-injecting drug users (NIDUs) when HIV prevalence declined from 16% to 8% among NIDUs in New York City. METHODS: Subjects were current non-injecting users of heroin and/or cocaine and who had never injected illicit drugs. Three thousand one hundred fifty-seven NIDU subjects were recruited between 2005 and 2014 among persons entering Mount Sinai Beth Israel substance use treatment programs. Structured interviews, HIV, and HSV-2 testing were administered. Change over time was assessed by comparing 2005 to 2010 with 2011 to 2014 periods. Herpes simplex virus type 2 incidence was estimated among persons who participated in multiple years. RESULTS: Herpes simplex virus type 2 prevalence was strongly associated with HIV prevalence (odds ratio, 3.9; 95% confidence interval, 2.9-5.1) from 2005 to 2014. Herpes simplex virus type 2 prevalence declined from 60% to 56% (P = 0.01). The percentage of NIDUs with neither HSV-2 nor HIV infection increased from 37% to 43%, (P < 0.001); the percentage with HSV-2/HIV coinfection declined from 13% to 6% (P < 0.001). Estimated HSV-2 incidence was 1 to 2/100 person-years at risk. CONCLUSIONS: There were parallel declines in HIV and HSV-2 among NIDUs in New York City from 2005 to 2014. The increase in the percentage of NIDUs with neither HSV-2 nor HIV infection, the decrease in the percentage with HSV-2/HIV coinfection, and the low to moderate HSV-2 incidence suggest some population-level protection against resurgence of HIV. Prevention efforts should be strengthened to end the combined HIV/HSV-2 epidemic among NIDUs in New York City.

RESUMEN

BACKGROUND: More than half of persons living with HIV (PLWH) in the United States are insufficiently engaged in HIV primary care and not taking antiretroviral therapy (ART), mainly African Americans/Blacks and Hispanics. In the proposed project, a potent and innovative research methodology, the multiphase optimization strategy (MOST), will be employed to develop a highly efficacious, efficient, scalable, and cost-effective intervention to increase engagement along the HIV care continuum. Whereas randomized controlled trials are valuable for evaluating the efficacy of multi-component interventions as a package, they are not designed to evaluate which specific components contribute to efficacy. MOST, a pioneering, engineering-inspired framework, addresses this problem through highly efficient randomized experimentation to assess the performance of individual intervention components and their interactions. We propose to use MOST to engineer an intervention to increase engagement along the HIV care continuum for African American/Black and Hispanic PLWH not well engaged in care and not taking ART. Further, the intervention will be optimized for cost-effectiveness. A similar set of multi-level factors impede both HIV care and ART initiation for African American/Black and Hispanic PLWH, primary among them individual- (e.g., substance use, distrust, fear), social- (e.g., stigma), and structural-level barriers (e.g., difficulties accessing ancillary services). Guided by a multi-level social cognitive theory, and using the motivational interviewing approach, the study will evaluate five distinct culturally based intervention components (i.e., counseling sessions, pre-adherence preparation, support groups, peer mentorship, and patient navigation), each designed to address a specific barrier to HIV care and ART initiation. These components are well-grounded in the empirical literature and were found acceptable, feasible, and promising with respect to efficacy in a preliminary study. METHODS/DESIGN: Study aims are: 1) using a highly efficient fractional factorial experimental design, identify which of five intervention components contribute meaningfully to improvement in HIV viral suppression, and secondary outcomes of ART adherence and engagement in HIV primary care; 2) identify mediators and moderators of intervention component efficacy; and 3) using a mathematical modeling approach, build the most cost-effective and efficient intervention package from the efficacious components. A heterogeneous sample of African American/Black and Hispanic PLWH (with respect to age, substance use, and sexual minority status) will be recruited with a proven hybrid sampling method using targeted sampling in community settings and peer recruitment (N = 512). DISCUSSION: This is the first study to apply the MOST framework in the field of HIV prevention and treatment. This innovative study will produce a culturally based HIV care continuum intervention for the nation's most vulnerable PLWH, optimized for cost-effectiveness, and with exceptional levels of efficacy, efficiency, and scalability.

RESUMEN

BACKGROUND: Hepatitis C virus (HCV) infection is hyperendemic among people who inject drugs; nonsterile drug injection is the principle risk for HCV acquisition. Due to gaps in the HCV care continuum, there have been recommendations in the United States emphasizing age-rather than risk-based testing strategies. The central research focus of this project is to explore the meanings and implications of the shift in emphasis from risk-based to age-based HCV testing with regard to people who use drugs. METHODS: Content analysis and critical discourse analysis, informed by eco-social theory, were used to examine relevant documents. RESULTS: Fifteen documents were assessed for eligibility; 6 documents comprised the final set reviewed. In content analysis, age-based testing was both mentioned more frequently and was supported more strongly than risk-based testing. Risk-based testing was frequently mentioned in terms minimizing its use and drug use was often mentioned only euphemistically. The reframed emphasis largely removed discussion of injection drug use from discussion of HCV risks. CONCLUSION: Shifting the emphasis of HCV testing from testing based on specific routes of transmission and risk to testing based on age removes injection drug use from HCV discourse. This has the potential to either facilitate HCV care for drug users or to further stigmatize and marginalize drug use and people who use drugs. The potential implications of this shift in testing emphasis for public health merit further investigation.

RESUMEN

People who use drugs (PWUDs) are at increased risk for several medical conditions, yet they delay seeking medical care and utilize emergency departments (EDs) as their primary source of care. Limited research regarding perceived discrimination and PWUDs' use of health care services exists. This study explores the association between interpersonal and institutional racial/ethnic and drug use discrimination in health care settings and health care utilization among respondents (N = 192) recruited from methadone maintenance treatment programs (36%), HIV primary care clinics (35%), and syringe exchange programs (29%) in New York City (n = 88) and San Francisco (n = 104). The Kaiser Family Foundation Survey of Race, Ethnicity, and Medical Care questionnaire was utilized to assess perceived institutional racial/ethnic and drug use discrimination. Perceived institutional discrimination was examined across race/ethnicity and by regular use of ERs, having a regular doctor, and consistent health insurance. Perceived interpersonal discrimination was examined by race/ethnicity. Perceived interpersonal drug use discrimination was the most common type of discrimination experienced in health care settings. Perceptions of institutional discrimination related to race/ethnicity and drug use among non-Hispanic Whites did not significantly differ from those among non-Hispanic Blacks or Hispanics. A perception of less frequent institutional racial/ethnic and drug use discrimination in health care settings was associated with increased odds of having a regular doctor. Awareness of perceived interpersonal and institutional discrimination in certain populations and the effect on health care service utilization should inform future intervention development to help reduce discrimination and improve health care utilization among PWUDs.

RESUMEN

New York City has experienced the largest HIV epidemic among persons who use psychoactive drugs. We examined progress in placing HIV seropositive persons who inject drugs (PWID) and HIV seropositive non-injecting drug users (NIDU) onto antiretroviral treatment (ART) in New York City over the last 15 years. We recruited 3511 PWID and 3543 NIDU from persons voluntarily entering drug detoxification and methadone maintenance treatment programs in New York City from 2001 to 2014. HIV prevalence declined significantly among both PWID and NIDU. The percentage who reported receiving ART increased significantly, from approximately 50 % (2001-2005) to approximately 75 % (2012-2014). There were no racial/ethnic disparities in the percentages of HIV seropositive persons who were on ART. Continued improvement in ART uptake and TasP and maintenance of other prevention and care services should lead to an "End of the AIDS Epidemic" for persons who use heroin and cocaine in New York City.

RESUMEN

Young people face greatly increased human immunodeficiency virus (HIV) risk and high rates of undiagnosed HIV, yet are unlikely to test. Many also have limited or inconsistent access to health care, including HIV testing and prevention education, and prior research has documented that youth lack knowledge necessary to understand the HIV test process and to interpret test results. Computer-based interventions have been used to increase HIV test rates and knowledge among emergency department (ED) patients, including those who decline tests offered at triage. However, patients aged 18-24 years have been less likely to test, even after completing an intervention, compared to older patients in the same ED setting. The current pilot study sought to examine the feasibility and acceptability of a new tablet-based video intervention designed to address established barriers to testing among ED patients aged 18-24 years. In particular, we examined whether young ED patients would: agree to receive the intervention; complete it quickly enough to avoid disrupting clinical workflows; accept HIV tests offered by the intervention; demonstrate increased postintervention knowledge; and report they found the intervention acceptable. Over 4 weeks, we recruited 100 patients aged 18-24 in a high-volume urban ED; all of them declined HIV tests offered at triage. Almost all (98%) completed the intervention (mean time <9 mins), 30% accepted HIV tests offered by the tablets. Knowledge was significantly higher after than before the intervention (t = -6.67, p < .001) and patients reported generally high acceptability. Additional research appears warranted to increase postintervention HIV testing.

RESUMEN

BACKGROUND: An estimated 14 % of the 1.2 million individuals living with HIV in the U.S. are unaware of their status. Yet this modest proportion of individuals with undiagnosed HIV is linked to 44-66 % of all new infections. Thus innovative intervention approaches are needed to seek out and test those with undiagnosed HIV, and link them to HIV treatment with high retention, an approach referred to as "Seek, Test, Treat, and Retain" (STTR). The present protocol describes a creative "hybrid" STTR approach that uses anonymous HIV testing followed by confidential care linkage, focused on heterosexuals at high risk (HHR) for HIV, who do not test as frequently as, and are diagnosed later, than other risk groups. METHODS/DESIGN: This is a single-arm exploratory intervention efficacy trial. The study has two phases: one to seek out and test HHR, and another to link those found infected to HIV treatment in a timely fashion, with high retention. We will recruit African American/Black and Latino adult HHR who reside in urban locations with high poverty and HIV prevalence. Participants will be recruited with respondent-driven sampling, a peer recruitment method. The "Seek and Test" phase is comprised of a brief, convenient, single-session, anonymous HIV counseling and testing session. The "Treat and Retain" component will engage those newly diagnosed with HIV into a confidential research phase and use a set of procedures called care navigation to link them to HIV primary care. Participants will be followed for 6 months with objective assessment of outcomes (using medical records and biomarkers). DISCUSSION: Undiagnosed HIV infection is a major public health problem. While anonymous HIV testing is an important part of the HIV testing portfolio, it does not typically include linkage to care. The present study has potential to produce an innovative, brief, cost-effective, and replicable STTR intervention, and thereby reduce racial/ethnic disparities in HIV/AIDS.
