Strategies of Managing Repeated Measures: Using Synthetic Random Forest to Predict HIV Viral Suppression Status Among Hospitalized Persons with HIV.

The HIV/AIDS epidemic remains a major public health concern since the 1980s; untreated HIV infection has numerous consequences on quality of life. To optimize patients' health outcomes and to reduce HIV transmission, this study focused on vulnerable populations of people living with HIV (PLWH) and compared different predictive strategies for viral suppression using longitudinal or repeated measures. The four methods of predicting viral suppression are (1) including the repeated measures of each feature as predictors, (2) utilizing only the initial (baseline) value of the feature as predictor, (3) using the last observed value as the predictors and (4) using a growth curve estimated from the features to create individual-specific prediction of growth curves as features. This study suggested the individual-specific prediction of the growth curve performed the best in terms of lowest error rate on an independent set of test data.

Daily Microaggressions and Related Distress among Black Women Living with HIV during the Onset of the COVID-19 Pandemic and Black Lives Matter Protests.

Black women living with HIV (BWLWH) in the U.S. face microaggressions based on race, gender, HIV-status, and sexual orientation. We examined changes in daily microaggressions and related distress among 143 BWLWH in Miami, FL. Microaggression-related distress increased from 52% at baseline/October, peaked at 70% during the holidays (November/December), declined to 55% in March when COVID-19 social distancing began, and peaked to 83% in June/July 2020 during widespread Black Lives Matters protests. Baseline viral suppression was associated with lower microaggressions across the 9-months. Microaggression-related distress may change due to social context and research is needed on microaggressions and viral load overtime.

RESUMEN: Las mujeres de raza negra que viven con el VIH (MNVV) en los EE. UU. enfrentan microagresiones basadas en la raza, el género, el estado serológico del VIH y la orientación sexual. Examinamos los cambios en las microagresiones diarias y el estrés relacionado entre 143 MNVV en Miami, FL. El estrés relacionado con la microagresión aumentó del 52% en la línea de base/octubre, alcanzó un máximo del 70% durante las vacaciones (noviembre/diciembre), disminuyó al 55% en marzo cuando comenzó el distanciamiento social por el COVID-19 y alcanzó un máximo del 83% en junio/julio de 2020 durante las protestas generalizadas de Black Lives Matters. La supresión viral inicial se asoció con menores microagresiones durante los 9 meses. El estrés relacionada con la microagresión puede cambiar debido al contexto social y se necesitan investigaciones sobre las microagresiones y la carga viral con el tiempo.

Trauma exposure, PTSD, and suboptimal HIV medication adherence among marginalized individuals connected to public HIV care in Miami.

Individuals living with HIV report disproportionately high levels of trauma exposure and PTSD symptoms, both which have been associated with suboptimal ART adherence. Often conflated, the question arises as to which construct is driving subsequent HIV self-care behavior. Given the HIV disparities among Black and Hispanic/Latinx individuals, and that Miami is a geographic region with a high racial/ethnic minority make up and a unique socioeconomic environment, it is important to explore factors related to HIV outcomes in Miami to mitigate its uncontrolled epidemic. This study aimed to examine the association of trauma exposure, PTSD symptoms, and relevant additional key factors with adherence to ART among a sample of majority Black and Hispanic/Latinx individuals who are economically marginalized receiving public HIV care in Miami, FL (N = 1237) via a cross-sectional survey. Sequential linear regression was used to examine the study aim in four blocks: (1) trauma, (2) PTSD symptoms, and key covariates of ART adherence including (3) depression and substance use (potential psychological covariates), and (4) indicators of socioeconomic status (potential structural covariates). In the first block, trauma exposure was associated with worse adherence. However, in the second block, the association with trauma dropped and PTSD was significantly associated with worse adherence. Of note, for those experiencing high levels of trauma exposure, adherence was negatively impacted regardless of PTSD. When other key factors associated with adherence were entered in the third and fourth blocks, neither trauma exposure nor PTSD were uniquely significant. In this final model, depression, substance use, and unstable housing were uniquely associated with worse adherence. Trauma-informed models of HIV care that holistically address co-occurring factors are warranted to cater to communities with HIV health disparities and keep them from falling off the HIV care continuum.

Dental Care Utilization of Hospitalized Persons Living with HIV and Substance Use.

People living with HIV (PLWH) who use drugs experience worse health outcomes than their non-using counterparts. Little is known about how often they seek dental care and the factors that influence their utilization. PLWH with substance use disorders who were inpatients at 11 urban hospitals (n = 801) participated in a National Institute on Drug Abuse Clinical Trials Network study to improve engagement in HIV outcomes. Dental care utilization at each time point during the study period (baseline, 6 months and/or 12 months) was assessed (n = 657). Univariate analysis and logistic regression were used to examine factors associated with dental care utilization. Over half (59.4%) reported not having received any dental care at any timepoint. Participants with less than high school education had lower odds of reporting dental care utilization than those with more than education (aOR = 0.60 [95% CI 0.37-0.99], p = 0.0382). Participants without health insurance also had lower odds of reporting dental care utilization than those with insurance (aOR = 0.50 [95% CI 0.331-0.76], p = 0.0012). Higher food insecurity was associated with having recent dental care utilization (OR = 1.03 [95% CI 1.00, 1.05], p = 0.0359). Additionally, those from Southern states were less likely to report dental care utilization (aOR = 0.55 [95% CI 0.38, 0.79], p = 0.0013). Having health insurance and education are key factors associated with use of dental care for PLWH with substance use disorders. The association between food insecurity and dental care utilization among this population suggests the need for further exploration.

Rapid Identification and Investigation of an HIV Risk Network Among People Who Inject Drugs -Miami, FL, 2018.

Prevention of HIV outbreaks among people who inject drugs remains a challenge to ending the HIV epidemic in the United States. The first legal syringe services program (SSP) in Florida implemented routine screening in 2018 leading to the identification of ten anonymous HIV seroconversions. The SSP collaborated with the Department of Health to conduct an epidemiologic investigation. All seven acute HIV seroconversions were linked to care (86% within 30 days) and achieved viral suppression (mean 70 days). Six of the seven individuals are epidemiologically and/or socially linked to at least two other seroconversions. Analysis of the HIV genotypes revealed that two individuals are connected molecularly at 0.5% genetic distance. We identified a risk network with complex transmission dynamics that could not be explained by epidemiological methods or molecular analyses alone. Providing wrap-around services through the SSP, including routine screening, intensive linkage and patient navigation, could be an effective model for achieving viral suppression for people who inject drugs.

Implementation of an Immediate HIV Treatment Initiation Program in a Public/Academic Medical Center in the U.S. South: The Miami Test and Treat Rapid Response Program.

Test and Rapid Response Treatment (TRRT) linkage programs have demonstrated improved HIV suppression rates. This paper describes the design and implementation of the Miami TRRT initiative and its clinical impact. Assisted by a dedicated care navigator, patients receiving a reactive HIV rapid test at the Florida Department of Health STD Clinic were offered same-day HIV care at the University of Miami/Jackson Memorial Medical Center Adult HIV Outpatient Clinic. Patient retention and labs were tracked for 12 months. Of the 2337 individuals tested, 46 had a reactive HIV test; 41 (89%) consented to participate. For the 36 patients in continued care for a year, 33 (91.7%) achieved virological suppression (< 200 copies/mL) within 70 days of their reactive HIV rapid test; at 12 months, 35 (97.2%) remained suppressed, and mean CD4 T cell counts increased from 452 ± 266 to 597 ± 322 cells/mm3. The Miami TRRT initiative demonstrated that immediate linkage to care is feasible and improves retention and suppression in a public/academic medical center in the U.S. South.

High Levels of Syndemics and Their Association with Adherence, Viral Non-suppression, and Biobehavioral Transmission Risk in Miami, a U.S. City with an HIV/AIDS Epidemic.

Miami is a Southeastern United States (U.S.) city with high health, mental health, and economic disparities, high ethnic/racial diversity, low resources, and the highest HIV incidence and prevalence in the country. Syndemic theory proposes that multiple, psychosocial comorbidities synergistically fuel the HIV/AIDS epidemic. People living with HIV/AIDS in Miami may be particularly affected by this due to the unique socioeconomic context. From April 2017 to October 2018, 800 persons living with HIV/AIDS in a public HIV clinic in Miami completed an interviewer-administered behavioral and chart-review cross-sectional assessment to examine the prevalence and association of number of syndemics (unstable housing, low education, depression, anxiety, binge drinking, drug use, violence, HIV-related stigma) with poor ART adherence, unsuppressed HIV viral load (≥ 200 copies/mL), and biobehavioral transmission risk (condomless sex in the context of unsuppressed viral load). Overall, the sample had high prevalence of syndemics (M = 3.8), with almost everyone (99%) endorsing at least one. Each syndemic endorsed was associated with greater odds of: less than 80% ART adherence (aOR 1.64, 95% CI 1.38, 1.98); having unsuppressed viral load (aOR 1.16, 95% CI 1.01, 1.33); and engaging in condomless sex in the context of unsuppressed viral load (1.78, 95% CI 1.30, 2.46). The complex syndemic of HIV threatens to undermine the benefits of HIV care and are important to consider in comprehensive efforts to address the disproportionate burden of HIV/AIDS in the Southern U.S. Achieving the 90-90-90 UNAIDS and the recent U.S. "ending the epidemic" targets will require efforts addressing the structural, social, and other syndemic determinants of HIV treatment and prevention.

Characterising HIV transmission risk among US patients with HIV in care: a cross-sectional study of sexual risk behaviour among individuals with viral load above 1500 copies/mL.

OBJECTIVES: Viral load and sexual risk behaviour contribute to HIV transmission risk. High HIV viral loads present greater transmission risk than transient viral 'blips' above an undetectable level. This paper therefore characterises sexual risk behaviour among patients with HIV in care with viral loads>1500 copies/mL and associated demographic characteristics. METHODS: This cross-sectional study was conducted at six HIV outpatient clinics in USA. The study sample comprises 1315 patients with HIV with a recent viral load >1500 copies/mL. This study sample was drawn from a larger sample of individuals with a recent viral load >1000 copies/mL who completed a computer-assisted self-interview (CASI) regarding sexual risk practices in the last 2 months. The study sample was 32% heterosexual men, 38% men who have sex with men (MSM) and 30% women. RESULTS: Ninety per cent of the sample had their viral load assay within 60 days of the CASI. Thirty-seven per cent reported being sexually active (vaginal or anal intercourse) in the last 2 months. Most of the sexually active participants reported always using condoms (56.9%) or limiting condomless sex to seroconcordant partners (serosorting; 29.2% overall and 42.9% among MSM). Among sexually active participants who reported condomless anal or vaginal sex with an at-risk partner (14%), most had viral loads>10 000 copies/mL (62%). CONCLUSIONS: A relatively small number of patients with HIV in care with viral loads above 1500 copies/mL reported concurrent sexual transmission risk behaviours. Most of the individuals in this small group had markedly elevated viral loads, increasing the probability of transmission. Directing interventions to patients in care with high viral loads and concurrent risk behaviour could strengthen HIV prevention and reduce HIV infections.

Psychosocial Factors Associated with Problem Drinking Among Substance Users with Poorly Controlled HIV Infection.

AIMS: We aimed to identify psychosocial factors related to problem drinking among patients with poorly controlled human immunodeficiency virus (HIV) infection. SHORT SUMMARY: We aimed to identify psychosocial factors related to problem drinking among those with poorly controlled HIV infection. Increased levels of interpersonal conflict were associated with greater severity of alcohol problems. Poorer mental health, medical mistrust and less satisfaction with one's physician related to excessive drinking. METHODS: This secondary analysis used baseline data from a large multisite randomized controlled trial of substance users whose HIV infection was currently poorly controlled, from 11 urban hospitals across the USA. Participants were HIV-infected adult inpatients (n = 801; 67% male, 75% African American) with substance use histories. Participants self-reported on their drinking, perceived health, mental health, social relationships and patient-provider relationship. Structural equation models examined psychosocial factors associated with problem drinking, controlling for demographic covariates. RESULTS: Increased levels of interpersonal conflict were associated with greater severity of alcohol problems. Poorer mental health, medical mistrust and less satisfaction with one's physician were associated with excessive drinking. CONCLUSIONS: Several psychosocial factors, including interpersonal conflict, poor mental health (i.e. anxiety, depression and somatization), medical mistrust and less satisfaction with one's provider, were associated with problem drinking among HIV-infected substance users with poorly controlled HIV infection. The co-occurrence of these concerns highlights the need for comprehensive services (including attention to problem drinking, social services, mental health and quality medical care) in this at-risk group.

The structural and health policy environment for delivering integrated HIV and substance use disorder treatments in Puerto Rico.

BACKGROUND: HIV prevalence in Puerto Rico is nearly twice that of the mainland United States, a level that was substantially fueled by injection drug use. Puerto Rico has a longstanding history of health provision by the public sector that directly affects how HIV and substance use disorder (SUD) treatment services are provided and funded. As part of pre-implementation research for a randomized trial of a community-level intervention to enhance HIV care access for substance users in San Juan, Puerto Rico, we sought to understand the structural and health policy environment for providing HIV and SUD treatments. METHODS: We conducted semi-structured qualitative interviews (n = 8) with government and program administrators in English and Spanish. Data were analyzed to identify dominant and recurrent themes. RESULTS: Participants discussed how lack of integration among medical and mental health service providers, lack of public transportation, and turnover in appointed government officials were barriers to integrated HIV and SUD treatment. Federal funding for support services for HIV patients was a facilitator. The Affordable Care Act has limited impact in Puerto Rico because provisions related to health insurance reform do not apply to U.S. territories. DISCUSSION AND CONCLUSIONS: Implications for intervention design include the need to provide care coordination for services from multiple providers, who are often physically separated and working in different reimbursement systems, and the potential for mobile and patient transportation services to bridge these gaps. Continuous interaction with political leaders is needed to maintain current facilitators. These findings are relevant as the current economic crisis in Puerto Rico affects funding, and may be relevant for other settings with substance use-driven epidemics.

HIV Risk Perception, HIV Knowledge, and Sexual Risk Behaviors among Transgender Women in South Florida.

OBJECTIVES: Transgender women experience a variety of factors that may contribute to HIV risk. The purpose of this study was to explore links among HIV risk perception, knowledge, and sexual risk behaviors of transgender women. DESIGN AND SAMPLE: A descriptive, correlational study design was used. Fifty transgender women from the South Florida area were enrolled in the study. MEASURES: Transgender women completed a demographic questionnaire and standardized instruments measuring HIV risk perception, knowledge, and sexual risk behaviors. RESULTS: Transgender women reported low levels of HIV risk perception, and had knowledge deficits regarding HIV risk/transmission. Some participants engaged in high-risk sexual behaviors. Predictors of sexual risk behaviors among transgender women were identified. CONCLUSIONS: More research is needed with a larger sample size to continue studying factors that contribute to sexual risk behaviors in the understudied population of transgender women. Evidence-based guidelines are available to assist public health nurses in providing care for transgender women. Nurses must assess HIV perception risk and HIV knowledge and provide relevant education to transgender women on ways to minimize sexual risk.

Effect of Patient Navigation With or Without Financial Incentives on Viral Suppression Among Hospitalized Patients With HIV Infection and Substance Use: A Randomized Clinical Trial.

IMPORTANCE: Substance use is a major driver of the HIV epidemic and is associated with poor HIV care outcomes. Patient navigation (care coordination with case management) and the use of financial incentives for achieving predetermined outcomes are interventions increasingly promoted to engage patients in substance use disorders treatment and HIV care, but there is little evidence for their efficacy in improving HIV-1 viral suppression rates. OBJECTIVE: To assess the effect of a structured patient navigation intervention with or without financial incentives to improve HIV-1 viral suppression rates among patients with elevated HIV-1 viral loads and substance use recruited as hospital inpatients. DESIGN, SETTING, AND PARTICIPANTS: From July 2012 through January 2014, 801 patients with HIV infection and substance use from 11 hospitals across the United States were randomly assigned to receive patient navigation alone (n = 266), patient navigation plus financial incentives (n = 271), or treatment as usual (n = 264). HIV-1 plasma viral load was measured at baseline and at 6 and 12 months. INTERVENTIONS: Patient navigation included up to 11 sessions of care coordination with case management and motivational interviewing techniques over 6 months. Financial incentives (up to $1160) were provided for achieving targeted behaviors aimed at reducing substance use, increasing engagement in HIV care, and improving HIV outcomes. Treatment as usual was the standard practice at each hospital for linking hospitalized patients to outpatient HIV care and substance use disorders treatment. MAIN OUTCOMES AND MEASURES: The primary outcome was HIV viral suppression (≤200 copies/mL) relative to viral nonsuppression or death at the 12-month follow-up. RESULTS: Of 801 patients randomized, 261 (32.6%) were women (mean [SD] age, 44.6 years [10.0 years]). There were no differences in rates of HIV viral suppression versus nonsuppression or death among the 3 groups at 12 months. Eighty-five of 249 patients (34.1%) in the usual-treatment group experienced treatment success compared with 89 of 249 patients (35.7%) in the navigation-only group for a treatment difference of 1.6% (95% CI, -6.8% to 10.0%; P = .80) and compared with 98 of 254 patients (38.6%) in the navigation-plus-incentives group for a treatment difference of 4.5% (95% CI -4.0% to 12.8%; P = .68). The treatment difference between the navigation-only and the navigation-plus-incentives group was -2.8% (95% CI, -11.3% to 5.6%; P = .68). CONCLUSIONS AND RELEVANCE: Among hospitalized patients with HIV infection and substance use, patient navigation with or without financial incentives did not have a beneficial effect on HIV viral suppression relative to nonsuppression or death at 12 months vs treatment as usual. These findings do not support these interventions in this setting. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01612169.

The Contribution of Missed Clinic Visits to Disparities in HIV Viral Load Outcomes.

OBJECTIVES: We explored the contribution of missed primary HIV care visits ("no-show") to observed disparities in virological failure (VF) among Black persons and persons with injection drug use (IDU) history. METHODS: We used patient-level data from 6 academic clinics, before the Centers for Disease Control and Prevention and Health Resources and Services Administration Retention in Care intervention. We employed staged multivariable logistic regression and multivariable models stratified by no-show visit frequency to evaluate the association of sociodemographic factors with VF. We used multiple imputations to assign missing viral load values. RESULTS: Among 10 053 patients (mean age = 46 years; 35% female; 64% Black; 15% with IDU history), 31% experienced VF. Although Black patients and patients with IDU history were significantly more likely to experience VF in initial analyses, race and IDU parameter estimates were attenuated after sequential addition of no-show frequency. In stratified models, race and IDU were not statistically significantly associated with VF at any no-show level. CONCLUSIONS: Because missed clinic visits contributed to observed differences in viral load outcomes among Black and IDU patients, achieving an improved understanding of differential visit attendance is imperative to reducing disparities in HIV.

Enhanced personal contact with HIV patients improves retention in primary care: a randomized trial in 6 US HIV clinics.

BACKGROUND: The aim of the study was to determine whether enhanced personal contact with human immunodeficiency virus (HIV)-infected patients across time improves retention in care compared with existing standard of care (SOC) practices, and whether brief skills training improves retention beyond enhanced contact. METHODS: The study, conducted at 6 HIV clinics in the United States, included 1838 patients with a recent history of inconsistent clinic attendance, and new patients. Each clinic randomized participants to 1 of 3 arms and continued to provide SOC practices to all enrollees: enhanced contact with interventionist (EC) (brief face-to-face meeting upon returning for care visit, interim visit call, appointment reminder calls, missed visit call); EC + skills (organization, problem solving, and communication skills); or SOC only. The intervention was delivered by project staff for 12 months following randomization. The outcomes during that 12-month period were (1) percentage of participants attending at least 1 primary care visit in 3 consecutive 4-month intervals (visit constancy), and (2) proportion of kept/scheduled primary care visits (visit adherence). RESULTS: Log-binomial risk ratios comparing intervention arms against the SOC arm demonstrated better outcomes in both the EC and EC + skills arms (visit constancy: risk ratio [RR], 1.22 [95% confidence interval {CI}, 1.09-1.36] and 1.22 [95% CI, 1.09-1.36], respectively; visit adherence: RR, 1.08 [95% CI, 1.05-1.11] and 1.06 [95% CI, 1.02-1.09], respectively; all Ps < .01). Intervention effects were observed in numerous patient subgroups, although they were lower in patients reporting unmet needs or illicit drug use. CONCLUSIONS: Enhanced contact with patients improved retention in HIV primary care compared with existing SOC practices. A brief patient skill-building component did not improve retention further. Additional intervention elements may be needed for patients reporting illicit drug use or who have unmet needs. CLINICAL TRIALS REGISTRATION: CDCHRSA9272007.

Low Levels of HIV Stigma Among Transgender Women Receiving HIV Care.

Despite the prevalence of HIV among transgender women (TGW), gaps exist in understanding the impact of HIV-related stigma (HRS) on TGW with HIV. This is a small cross-sectional pilot study examining HRS in TGW (n=18) with HIV in Miami, FL, who completed a survey during an HIV clinical visit. In contrast with previous studies, results demonstrated low levels of HRS and suggest the potential of increasing acceptance of TGW with HIV as a contributing factor. Larger studies are needed to explore factors underlying HRS with the aim of further reducing stigma among TGW with HIV.

The Perils of Overly Sensitive Viral Load Testing for Persons With Human Immunodeficiency Virus.

The concept of "undetectable = untransmittable (U = U)" has been revolutionary in both the prevention and treatment of persons with human immunodeficiency virus (HIV). Most studies proving the concept of U = U used an HIV RNA (viral load [VL]) cutoff of 200 copies/mL to define being undetectable. Since then, increasingly sensitive commercial VL assays, sometimes down to a lower limit of detection (LLD) of 20 copies/mL, lead to confusion about the definition of "undetectable" and when someone is truly considered untransmittable. VLs between the LLD and 200 copies/mL have been associated with future virologic failure; however, no data exist to suggest that intervening in those patients leads to any meaningful benefits. In the absence of a demonstrable benefit of reporting such low VLs, we view this practice as harmful. We suggest recommendations for adjusting VL reporting and improving provider counseling, and call for research designs to mitigate the harms of overly sensitive VL testing.

Implementation of an integrated infectious disease and substance use disorder team for injection drug use-associated infections: a qualitative study.

BACKGROUND: Hospitalizations for severe injection drug use-related infections (SIRIs) are characterized by high costs, frequent patient-directed discharge, and high readmission rates. Beyond the health system impacts, these admissions can be traumatizing to people who inject drugs (PWID), who often receive inadequate treatment for their substance use disorders (SUD). The Jackson SIRI team was developed as an integrated infectious disease/SUD treatment intervention for patients hospitalized at a public safety-net hospital in Miami, Florida in 2020. We conducted a qualitative study to identify patient- and clinician-level perceived implementation barriers and facilitators to the SIRI team intervention. METHODS: Participants were patients with history of SIRIs (n = 7) and healthcare clinicians (n = 8) at one implementing hospital (Jackson Memorial Hospital). Semi-structured qualitative interviews were performed with a guide created using the Consolidated Framework for Implementation Research (CFIR). Interviews were transcribed, double coded, and categorized by study team members using CFIR constructs. RESULTS: Implementation barriers to the SIRI team intervention identified by participants included: (1) complexity of the SIRI team intervention; (2) lack of resources for PWID experiencing homelessness, financial insecurity, and uninsured status; (3) clinician-level stigma and lack of knowledge around addiction and medications for opioid use disorder (OUD); and (4) concerns about underinvestment in the intervention. Implementation facilitators of the intervention included: (1) a non-judgmental, harm reduction-oriented approach; (2) the team's advocacy for PWID as a means of institutional culture change; (3) provision of close post-hospital follow-up that is often inaccessible for PWID; (4) strong communication with patients and their hospital physicians; and (5) addressing diverse needs such as housing, insurance, and psychological wellbeing. CONCLUSION: Integration of infectious disease and SUD treatment is a promising approach to managing patients with SIRIs. Implementation success depends on institutional buy-in, holistic care beyond the medical domain, and an ethos rooted in harm reduction across multilevel (inner and outer) implementation contexts.

Lessons learned from U.S. rapid antiretroviral therapy initiation programs.

BACKGROUND: Rapid antiretroviral therapy initiation (R-ART) for treatment of HIV has been recommended since 2017, however it has not been adopted widely across the US. PURPOSE: The study purpose was to understand facilitators and barriers to R-ART implementation in the U.S. RESEARCH DESIGN: This was a qualitative design involving semi-structured interviews. STUDY SAMPLE: The study sample was comprised of the medical leadership of nine US HIV clinics that were early implementers of R-ART. DATA COLLECTION AND ANALYSIS: In-depth, semi-structured interviews were performed. The Consolidated Framework for Implementation Research (CFIR) was used to guide thematic analysis. RESULTS: We identified three main content areas: strong scientific rationale for R-ART, buy-in from multiple key stakeholders, and the condensed timeline of R-ART. The CFIR construct of Evidence Strength and Quality was cited as an important factor in R-ART implementation. Buy-in from key stakeholders and immediate access to medications ensured the success of R-ART implementation. Patient acceptance of the condensed timeline for ART initiation was facilitated when presented in a patient-centered manner, including empathetic communication and addressing other patient needs concurrently. The condensed timeline of R-ART presented logistical challenges and opportunities for the development of intense patient-provider relationships. CONCLUSIONS: Results from the analysis showed that R-ART implementation should address the following: 1) logistical planning to implement HIV treatment with a condensed timeline 2) patients' mixed reactions to a new HIV diagnosis and 3) the high cost of HIV medications.

Integrated Infectious Disease and Substance Use Disorder Care for the Treatment of Injection Drug Use-Associated Infections: A Prospective Cohort Study With Historical Control.

Background: To address the infectious disease (ID) and substance use disorder (SUD) syndemic, we developed an integrated ID/SUD clinical team rooted in harm reduction at a county hospital in Miami, Florida. The Severe Injection-Related Infection (SIRI) team treats people who inject drugs (PWID) and provides medical care, SUD treatment, and patient navigation during hospitalization and after hospital discharge. We assessed the impact of the SIRI team on ID and SUD treatment and healthcare utilization outcomes. Methods: We prospectively collected data on patients seen by the SIRI team. A diagnostic code algorithm confirmed by chart review was used to identify a historical control group of patients with SIRI hospitalizations in the year preceding implementation of the SIRI team. The primary outcome was death or readmission within 90 days post-hospital discharge. Secondary outcomes included initiation of medications for opioid use disorder (MOUD) and antibiotic course completion. Results: There were 129 patients included in the study: 59 in the SIRI team intervention and 70 in the pre-SIRI team control group. SIRI team patients had a 45% risk reduction (aRR, 0.55 [95% confidence interval CI, .32-.95]; 24% vs 44%) of being readmitted in 90 days or dying compared to pre-SIRI historical controls. SIRI team patients were more likely to initiate MOUD in the hospital (93% vs 33%, P < .01), complete antibiotic treatment (90% vs 60%, P < .01), and less likely to have patient-directed discharge (17% vs 37%, P = .02). Conclusions: An integrated ID/SUD team was associated with improvements in healthcare utilization, MOUD initiation, and antibiotic completion for PWID with infections.

HIV incidence and mortality in transgender women in the eastern and southern USA: a multisite cohort study.

BACKGROUND: Epidemiological monitoring of HIV among transgender women is minimal despite prioritisation of this group in the US National HIV/AIDS Strategy (2022-2025). We aimed to estimate HIV incidence in a multisite cohort of transgender women in the eastern and southern USA. Participant deaths were identified during follow-up; thus, we felt it was an ethical imperative to report mortality alongside HIV incidence. METHODS: In this study, we established a multisite cohort across two modes: a site-based, technology-enhanced mode in six cities (Atlanta, Baltimore, Boston, Miami, New York City, and Washington, DC) and an exclusively digital mode that spanned 72 eastern and southern US cities that matched the six site-based cities based on population size and demographics. Trans feminine adults (≥18 years) who were not living with HIV were eligible and followed up for at least 24 months. Participants completed surveys and oral fluid HIV testing with clinical confirmation. We ascertained deaths through community and clinical sources. We estimated HIV incidence and mortality using the number of HIV seroconversions and deaths, respectively, divided by person-years accumulated from enrolment. Logistic regression models were used to identify predictors of HIV seroconversion (primary outcome) or death. FINDINGS: Between March 22, 2018, and Aug 31, 2020, we enrolled 1312 participants with 734 (56%) in site-based and 578 (44%) in digital modes. At the 24-month assessment, 633 (59%) of 1076 eligible participants consented to extending participation. 1084 (83%) of 1312 participants were retained at this analysis based on the study definition of loss to follow-up. As of May 25, 2022, the cohort participants had contributed 2730 accumulated person-years to the analytical dataset. Overall HIV incidence was 5·5 (95% CI 2·7-8·3) per 1000 person-years and incidence was higher among Black participants and those living in the south. Nine participants died during the study. The overall mortality rate was 3·3 (95% CI 1·5-6·3) per 1000 person-years, and the rate was higher among Latinx participants. Identical predictors of HIV seroconversion and death included residence in southern cities, sexual partnerships with cisgender men, and use of stimulants. Participation in the digital cohort and seeking care for gender transition were inversely associated with both outcomes. INTERPRETATION: As HIV research and interventions are increasingly delivered online, differences by mode highlight the need for continued community and location-based efforts to reach the most marginalised transgender women. Our findings underscore community calls for interventions that address social and structural contexts that affect survival and other health concerns alongside HIV prevention.
