Trends in Racial and Ethnic Disparities in Antiretroviral Therapy Prescription and Viral Suppression in the United States, 2009-2013

Explaining inequity in knowledge, attitude, and services related to HIV/AIDS: a systematic review

BACKGROUND

Equitable service provision and coverage are important responses to end the threat of the HIV/AIDS pandemic. Understanding inequity supports policies and programmes to deliver tailored interventions. There is continuous evidence generation on inequity in HIV/AIDS services. However, there was a lack of evidence on the global picture of inequity in behavioural and biomedical services related to HIV/AIDS. This systematic review assessed inequities in knowledge, attitude, HIV testing, and ART coverage across individual-level social groups and multiple (dis)advantage categories.

METHODS

This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline, with a PROSPERO registration number CRD42024521247. The risk of bias was assessed by using Hoy et al's and Joanna Brigg's quality appraisal checklists for cross-sectional quantitative and qualitative studies, respectively. The search date was from inception to the final database search date (May 29, 2023). The included articles were either quantitative or qualitative studies. We used mixed-methods approach to analyse the data from the review articles. Quantitative descriptive analysis was conducted to estimate frequency of articles published from different countries around the world. Qualitative content analysis of the findings from the original studies was conducted using the PROGRESS plus framework which stands for: place of residence, occupation or employment status, gender, religion, education status, socioeconomic status, and social capital.

RESULTS

Out of 6,029 articles that were accessed and screened, only 72 articles met the inclusion criteria. More articles on HIV-related equity in knowledge, attitude, testing, and ART were published in developed countries than in developing countries. Individuals from higher-income households had better knowledge about HIV/AIDS. Unfavourable attitudes towards people living with HIV and HIV/AIDS-associated stigma were common among women. HIV/AIDS service coverage (HIV testing or ART coverage) was higher among richer and urban residents. HIV/AIDS-associated stigma and lower levels of knowledge about HIV/AIDS were observed among multiple disadvantageous groups due to the intersection of two or more identities.

CONCLUSIONS

The current review revealed that there have been disparities in HIV/AIDS services between social classes. Ending service disparity towards the global threat of HIV/AIDS demands tailored interventions based on socially disadvantaged groups (e.g., poor, rural dwellers, and women) and intersectional determinants. There is a need to understand the deep-rooted causes of inequity and the challenges that an equity-oriented system faces over time. More studies on inequity are needed, including intersectional inequity, which has been rarely studied in developing countries.

Acceptability of Long-Acting Injectable Antiretroviral Therapy Among People with HIV Receiving Care at Three Ryan White Funded Clinics in the United States

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.

Antiretroviral Therapy Use and Disparities Among Medicare Beneficiaries with HIV

BACKGROUND

Antiretroviral therapy (ART) is recommended for all people with HIV. Understanding ART use among Medicare beneficiaries with HIV is therefore critically important for improving quality and equity of care among the growing population of older adults with HIV. However, a comprehensive national evaluation of filled ART prescriptions among Medicare beneficiaries is lacking.

OBJECTIVE

To examine trends in ART use among Medicare beneficiaries with HIV from 2013 to 2019 and to evaluate whether racial and ethnic disparities in ART use are narrowing over time.

DESIGN

Retrospective observational study.

SUBJECTS

Traditional Medicare beneficiaries with Part D living with HIV in 2013-2019.

MAIN MEASURES

Months of filled ART prescriptions each year.

KEY RESULTS

Compared with beneficiaries not on ART, beneficiaries on ART were younger, less likely to be Black (41.6% vs. 47.0%), and more likely to be Hispanic (13.1% vs. 9.7%). While the share of beneficiaries who filled ART prescriptions for 10 + months/year improved (+ 0.48 percentage points/year [p.p.y.], 95% CI 0.34-0.63, p < 0.001), 25.8% of beneficiaries did not fill ART for 10 + months in 2019. Between 2013 and 2019, the proportion of beneficiaries who filled ART for 10 + months improved for Black beneficiaries (65.8 to 70.3%, + 0.66 p.p.y., 95% CI 0.43-0.89, p < 0.001) and White beneficiaries (74.8 to 77.4%, + 0.38 p.p.y.; 95% CI 0.19-0.58, p < 0.001), while remaining stable for Hispanic beneficiaries (74.5 to 75.0%, + 0.12 p.p.y., 95% CI - 0.24-0.49, p = 0.51). Although Black-White disparities in ART use narrowed over time, the share of beneficiaries who filled ART prescriptions for 10 + months/year was significantly lower among Black beneficiaries relative to White beneficiaries each year.

CONCLUSIONS

ART use improved from 2013 to 2019 among Medicare beneficiaries with HIV. However, about 25% of beneficiaries did not consistently fill ART prescriptions within a given year. Despite declining differences between Black and White beneficiaries, concerning disparities in ART use persist.

Explaining racial and ethnic disparities in antiretroviral therapy adherence and viral suppression among U.S. men who have sex with men

OBJECTIVE

To identify factors - including social determinants of health (SDOH) - that explain racial/ethnic disparities in antiretroviral therapy (ART) adherence and sustained viral suppression (SVS) among U.S. men who have sex with men (MSM) with HIV.

DESIGN

We used weighted data from 2017-2021 cycles of the Medical Monitoring Project.

METHODS

Among MSM taking ART, we calculated prevalence differences (PDs) with 95% confidence intervals (CIs) of ART adherence (100% ART adherence, past 30 days) and SVS (all viral loads in past 12 months <200 copies/ml or undetectable) for Black MSM (BMSM) and Hispanic/Latino MSM (HMSM) compared with White MSM (WMSM). Using forward stepwise selection, we calculated adjusted PDs with 95% CIs to examine if controlling for selected variables reduced PDs.

RESULTS

After adjusting for age, any unmet service need, federal poverty level (FPL), food insecurity, homelessness, time since HIV diagnosis, gap in health coverage, and education, the BMSM/WMSM PD for ART adherence reduced from -16.9 to -8.2 (51.5%). For SVS, the BMSM/WMSM PD reduced from -8.3 to -3.6 (56.6%) after adjusting for ART adherence, age, homelessness, food insecurity, gap in health coverage, FPL, any unmet service need, time since diagnosis, and ER visit(s). The HMSM/WMSM PD for ART adherence reduced from -9.3 to -2.9 (68.8%) after adjusting for age and FPL. The unadjusted HMSM/WMSM PD for SVS was not statistically significant.

CONCLUSIONS

Adjusting for SDOH and other factors greatly reduced racial/ethnic disparities in ART adherence and SVS. Addressing these factors - particularly among BMSM - could substantially improve health equity among MSM with HIV.

Patient Education and Decision Support for Long-Acting Injectable HIV Antiretroviral Therapy: Protocol for Tool Development and Pilot Testing with Ryan White HIV/AIDS Program Medical Case Management Programs in New York

BACKGROUND

Long-acting injectable (LAI) HIV antiretroviral therapy (ART) presents a major opportunity to facilitate and sustain HIV viral suppression, thus improving health and survival among people living with HIV and reducing the risk of onward transmission. However, realizing the public health potential of LAI ART requires reaching patients who face barriers to daily oral ART adherence and thus can clinically benefit from alternative treatment modalities. Ryan White HIV/AIDS Program Part A medical case management (MCM) programs provide an array of services to address barriers to HIV care and treatment among economically and socially marginalized people living with HIV. These programs have demonstrated effectiveness in improving engagement along the continuum of care, but findings of limited program impact on durable viral suppression highlight the need to further innovate and hone strategies to support long-term ART adherence.

OBJECTIVE

This study aims to adapt and expand Ryan White MCM service strategies to integrate LAI ART regimen options, with the larger goal of improving health outcomes in the populations that could most benefit from alternatives to daily oral ART regimens.

METHODS

In 3 phases of work involving patient and provider participants, this study uses role-specific focus groups to elicit perceptions of LAI versus daily oral ART; discrete choice experiment (DCE) surveys to quantify preferences for different ART delivery options and related supports; and a nonrandomized trial to assess the implementation and utility of newly developed tools at 6 partnering Ryan White HIV/AIDS Program Part A MCM programs based in urban, suburban, and semirural areas of New York. Findings from the focus groups and DCEs, as well as feedback from advisory board meetings, informed the design and selection of the tools: a patient-facing, 2-page fact sheet, including frequently asked questions and a side-by-side comparison of LAI with daily oral ART; a patient-facing informational video available on YouTube (Google Inc); and a patient-provider decision aid. Implementation outcomes, measured through provider interviews, surveys, and service reporting, will guide further specification of strategies to integrate LAI ART options into MCM program workflows.

RESULTS

The study was funded in late April 2021 and received approval from the institutional review board in May 2021 under protocol 20-096. Focus groups were conducted in late 2021 (n=21), DCEs ran from June 2022 to January 2023 (n=378), and tools for piloting were developed by May 2023. The trial (May 2023 through January 2024) has enrolled >200 patients.

CONCLUSIONS

This study is designed to provide evidence regarding the acceptability, feasibility, appropriateness, and utility of a package of patient-oriented tools for comparing and deciding between LAI ART and daily oral ART options. Study strengths include formative work to guide tool development, a mixed methods approach, and the testing of tools in real-world safety-net service settings.

Ongoing Healthcare Disparities in neuroHIV: Addressing Gaps in the Care Continuum

PURPOSE OF REVIEW

We aim to review the neurological complications of HIV and the social, cultural, and economic inequalities that contribute to disparities in neuroHIV care.

RECENT FINDINGS

Disparities in diagnostics and care of patients with neurological infections and non-infectious conditions associated with HIV in both high-income and low-to-middle-income countries (LMIC) are common. The COVID-19 pandemic has exacerbated these disparities. Factors, such as HIV-related stigma, may deter people from accessing HIV treatment. First-line recommended treatments for neurological infections are not available in many LMICs, leading to inadequate treatment and exposure to agents with more harmful side effect profiles. Access-related factors, such as lack of transportation, lack of health insurance, and inadequate telehealth access, may increase the risk of HIV-related neurological complications. Further research is needed to increase awareness of neurological complications among providers and PWH, and regional guidelines should be considered to better address these complications.

Extracutaneous Kaposi sarcoma risk remains higher in people with HIV in the post-ART era

OBJECTIVE

To assess Kaposi sarcoma (KS) by HIV-status in Sweden 1983-2017, with particular focus on extracutaneous KS.

DESIGN

Population-based study linking the Total Population Registry, the Swedish HIV Registry InfCareHIV, and the Swedish Cancer Registry.

METHODS

We included all Swedish residents, born in or outside Sweden between 1940 and 2000 ( n  = 8 587 829), assessing the annual incidence of KS, adjusted hazard ratios (adjHR), and odds ratios (adjOR) in the pre and postcombination antiretroviral therapy (ART) eras.

RESULTS

KS was found in 324 individuals of whom 202 (62%) were people with HIV (PWH). While the incidence of KS decreased in PWH, it remained higher compared to HIV-negative at end of follow-up (28 vs. 0.09 per 100 000 person-years, P  < 0.001). In the post-ART era, PWH still had an increased risk of both cutaneous [adjHR 616, 95% confidence interval (CI) 410-926] and extracutaneous KS (adjHR 2068, 95% CI 757-5654), compared to HIV-negative individuals, although there were no cases of extracutaneous disease among virally suppressed PWH. In the post-ART era, the relative risk for KS remained higher in men, particularly men who have sex with men, and viral suppression was associated with lower odds of KS (adjOR 0.05, 95% CI 0.03-0.09).

CONCLUSIONS

KS remained increased in PWH in the post-ART era, with a particularly high risk for extracutaneous disease compared to HIV-negative individuals. Notably, there were no cases of extracutaneous disease among virally suppressed PWH, suggesting a less aggressive disease in this population. Further studies on KS in virally suppressed PWH are warranted.

Race, Healthcare, and Health Disparities: A Critical Review and Recommendations for Advancing Health Equity

An overwhelming body of evidence points to an inextricable link between race and health disparities in the United States. Although race is best understood as a social construct, its role in health outcomes has historically been attributed to increasingly debunked theories of underlying biological and genetic differences across races. Recently, growing calls for health equity and social justice have raised awareness of the impact of implicit bias and structural racism on social determinants of health, healthcare quality, and ultimately, health outcomes. This more nuanced recognition of the role of race in health disparities has, in turn, facilitated introspective racial disparities research, root cause analyses, and changes in practice within the medical community. Examining the complex interplay between race, social determinants of health, and health outcomes allows systems of health to create mechanisms for checks and balances that mitigate unfair and avoidable health inequalities. As one of the specialties most intertwined with social medicine, emergency medicine (EM) is ideally positioned to address racism in medicine, develop health equity metrics, monitor disparities in clinical performance data, identify research gaps, implement processes and policies to eliminate racial health inequities, and promote anti-racist ideals as advocates for structural change. In this critical review our aim was to (a) provide a synopsis of racial disparities across a broad scope of clinical pathology interests addressed in emergency departments-communicable diseases, non-communicable conditions, and injuries-and (b) through a race-conscious analysis, develop EM practice recommendations for advancing a culture of equity with the potential for measurable impact on healthcare quality and health outcomes.

Trends and Economic Implications of Disparities in Postoperative Pneumonia

BACKGROUND

Postoperative pneumonia is the third most common surgical complication and can seriously impair surgical rehabilitation and lead to related morbidity and mortality. We evaluated the temporal trends in racial and ethnic disparities in postoperative pneumonia and quantified the economic burden resulting from these inequalities in the United States.

METHODS

This population-based study includes 195 028 children (weighted to 964 679) admitted for elective surgery across 5340 US hospitals reporting to the Nationwide Inpatient Sample between 2010 and 2018. We estimated the risk-adjusted incidence of postoperative pneumonia, comparing racial and ethnic groups. We also quantified the inflation-adjusted hospital costs attributable to racial and ethnic disparities in postoperative pneumonia.

RESULTS

The risk-adjusted rates of pneumonia declined across all racial and ethnic categories, with Black children having the lowest annual rate of decline (Black: 0.03 percentage points, Hispanic: 0.05 percentage points, white: 0.05 percentage points). The risk-adjusted rates of pneumonia trended consistently higher for Black and Hispanic children, relative to white children, throughout the study period (Black versus white: relative risk, 1.31 (95% confidence interval, 1.14-1.51), P < .01; Hispanic versus white: relative risk, 1.16 (95% confidence interval, 1.02-1.32), P = .02). These disparities did not narrow significantly over time. During the study period, the excess hospitalization cost attributable to racial and ethnic disparities in postoperative pneumonia was $24 533 458 for Black children and $26 200 783 for Hispanic children (total, $50 734 241).

CONCLUSIONS

Against the backdrop of decreasing postoperative pneumonia, Black and Hispanic children continue to experience higher rates compared with white children. These persistent disparities in postoperative pneumonia were associated with considerable excess cost of surgical care.

First Demonstration Project of Long-Acting Injectable Antiretroviral Therapy for Persons With and Without Detectable Human Immunodeficiency Virus (HIV) Viremia in an Urban HIV Clinic

BACKGROUND

Long-acting injectable antiretroviral therapy (LAI-ART) is approved for treatment-naive or experienced people with human immunodeficiency virus (HIV; PWH) based on trials that only included participants with viral suppression. We performed the first LAI-ART demonstration project to include PWH unable to achieve or maintain viral suppression due to challenges adhering to oral ART.

METHODS

Ward 86 is a large HIV clinic in San Francisco that serves publicly insured and underinsured patients. We started patients on LAI-ART via a structured process of provider referral, multidisciplinary review (MD, RN, pharmacist), and monitoring for on-time injections. Inclusion criteria were willingness to receive monthly injections and a reliable contact method.

RESULTS

Between June 2021 and April 2022, 51 patients initiated LAI-ART, with 39 receiving at least 2 follow-up injections by database closure (median age, 46 years; 90% cisgender men, 61% non-White, 41% marginally housed, 54% currently using stimulants). Of 24 patients who initiated injections with viral suppression (median CD4 cell count, 706 cells/mm3), 100% (95% confidence interval [CI], 86%-100%) maintained viral suppression. Of 15 patients who initiated injections with detectable viremia (median CD4 cell count, 99 cells/mm3; mean log10 viral load, 4.67; standard deviation, 1.16), 12 (80%; 95% CI, 55%-93%) achieved viral suppression, and the other 3 had a 2-log viral load decline by a median of 22 days.

CONCLUSIONS

This small demonstration project of LAI-ART in a diverse group of patients with high levels of substance use and marginal housing demonstrated promising early treatment outcomes, including in those with detectable viremia due to adherence challenges. More data on LAI-ART in hard-to-reach populations are needed.

Factors Associated with Geographic Patterns of Poor Sustained Viral Suppression in Miami-Dade County Florida, 2017

BACKGROUND

Identifying geographic locations most affected by the HIV epidemic is essential to addressing disparities that impact people living with HIV. This study sought to identify individual and neighborhood-level factors that are associated with residing in geographic hotspots of poor sustained HIV viral suppression.

METHODS

Using data from the Miami-Dade County Ryan White HIV/AIDS program, spatial autocorrelation of poor sustained viral suppression (at least 1 laboratory test ≥ 200 copies/ml in 2017) was investigated using Global Moran's I followed by Local Moran's I and Getis Ord Gi* statistics by ZIP code tabulation areas (ZCTAs). Subsequently, multivariable logistic regression analysis was conducted to identify factors associated with residing in geographic hotspots of poor sustained viral suppression.

RESULTS

Several ZCTAs in the northern part of the county, accounting for 1/3 of the Ryan White program clients, had significantly higher clustering of poor sustained viral suppression. Client-level sociodemographic characteristics such as race/ethnicity, age, and poverty, and neighborhood-level characteristics (socioeconomic disadvantage index, residential instability index, and racial/language homogeneity index) were significantly associated with living in a hotspot of poor sustained viral suppression.

CONCLUSION

These findings highlight that spatial variation in sustained viral suppression exists within the county. Targeted strategies that address structural factors and the needs of people with HIV living in specified geographic areas may improve their HIV health outcomes and contribute towards local, regional, and national goals of ending the HIV epidemic.

Association of Race and Ethnicity With Initial Prescription of Antiretroviral Therapy Among People With HIV in the US

Importance

Integrase strand transfer inhibitor (INSTI)-containing antiretroviral therapy (ART) is currently the guideline-recommended first-line treatment for HIV. Delayed prescription of INSTI-containing ART may amplify differences and inequities in health outcomes.

Objectives

To estimate racial and ethnic differences in the prescription of INSTI-containing ART among adults newly entering HIV care in the US and to examine variation in these differences over time in relation to changes in treatment guidelines.

Design, Setting, and Participants

Retrospective observational study of 42 841 adults entering HIV care from October 12, 2007, when the first INSTI was approved by the US Food and Drug Administration, to April 30, 2019, at more than 200 clinical sites contributing to the North American AIDS Cohort Collaboration on Research and Design.

Exposures

Combined race and ethnicity as reported in patient medical records.

Main Outcomes and Measures

Probability of initial prescription of ART within 1 month of care entry and probability of being prescribed INSTI-containing ART. Differences among non-Hispanic Black and Hispanic patients compared with non-Hispanic White patients were estimated by calendar year and time period in relation to changes in national guidelines on the timing of treatment initiation and recommended initial treatment regimens.

Results

Of 41 263 patients with information on race and ethnicity, 19 378 (47%) as non-Hispanic Black, 6798 (16%) identified as Hispanic, and 13 539 (33%) as non-Hispanic White; 36 394 patients (85%) were male, and the median age was 42 years (IQR, 30 to 51). From 2007-2015, when guidelines recommended treatment initiation based on CD4+ cell count, the probability of ART initiation within 1 month of care entry was 45% among White patients, 45% among Black patients (difference, 0% [95% CI, -1% to 1%]), and 51% among Hispanic patients (difference, 5% [95% CI, 4% to 7%]). From 2016-2019, when guidelines strongly recommended treating all patients regardless of CD4+ cell count, this probability increased to 66% among White patients, 68% among Black patients (difference, 2% [95% CI, -1% to 5%]), and 71% among Hispanic patients (difference, 5% [95% CI, 1% to 9%]). INSTIs were prescribed to 22% of White patients and only 17% of Black patients (difference, -5% [95% CI, -7% to -4%]) and 17% of Hispanic patients (difference, -5% [95% CI, -7% to -3%]) from 2009-2014, when INSTIs were approved as initial therapy but were not yet guideline recommended. Significant differences persisted for Black patients (difference, -6% [95% CI, -8% to -4%]) but not for Hispanic patients (difference, -1% [95% CI, -4% to 2%]) compared with White patients from 2014-2017, when INSTI-containing ART was a guideline-recommended option for initial therapy; differences by race and ethnicity were not statistically significant from 2017-2019, when INSTI-containing ART was the single recommended initial therapy for most people with HIV.

Conclusions and Relevance

Among adults entering HIV care within a large US research consortium from 2007-2019, the 1-month probability of ART prescription was not significantly different across most races and ethnicities, although Black and Hispanic patients were significantly less likely than White patients to receive INSTI-containing ART in earlier time periods but not after INSTIs became guideline-recommended initial therapy for most people with HIV. Additional research is needed to understand the underlying racial and ethnic differences and whether the differences in prescribing were associated with clinical outcomes.

Universal Health Coverage for Antiretroviral Treatment: A Review

Universal health coverage is essential for the progress to end threats of the acquired immunodeficiency syndrome epidemic. The current review assesses the publication rate, strategies and barriers for antiretroviral therapy (ART) coverage, equity, quality of care, and financial protection. We searched Web of Science, PubMed, and Google Scholar. Of the available articles, 43.13% were on ART coverage, 40.28% were on financial protection, 10.43% were on quality of care, and 6.16% were on equity. A lack of ART, fear of unwanted disclosure, lack of transportation, unaffordable health care costs, long waiting time to receive care, and poverty were barriers to ART coverage. Catastrophic health care costs were higher among individuals who were living in rural settings, walked greater distances to reach health care institutions, had a lower socioeconomic status, and were immunocompromised. There were challenges to the provision of quality of care, including health care providers' inadequate salary, high workload and inadequate health workforce, inappropriate infrastructure, lack of training opportunities, unclear division of responsibility, and the presence of strict auditing. In conclusion, ART coverage was below the global average, and key populations were disproportionally less covered with ART in most countries. Huge catastrophic health expenditures were observed. UHC contexts of ART will be improved by reaching people with poor socioeconomic status, delivering appropriate services, establishing a proper health workforce and service stewardship.

Trends in Use of Combination Antiretroviral Therapy and Treatment Response from 2000 to 2016 in the Canadian Observational Cohort (CANOC): A Longitudinal Cohort Study

Background

Advances in treatment have turned HIV from a terminal illness to a more manageable condition. Over the past 20 years, there have been considerable changes to HIV treatment guidelines, including changes in preferred antiretrovirals and timing of initiation of combination antiretroviral therapy (cART).

Objective

To examine real-world trends in cART utilization, viral control, and immune reconstitution among people living with HIV in Canada.

Methods

Data were obtained from the Canadian Observational Cohort (CANOC). CANOC participants were eligible if they were antiretroviral therapy-naive at entry and initiated 3 or more antiretrovirals on or after January 1, 2000; if they were at least 18 years of age at treatment initiation; if they were residing in Canada; and if they had at least 1 viral load determination and CD4 count within 1 year of CANOC entry. Baseline and annual mean CD4 counts were categorized as less than 200, 200-350, 351-500, and more than 500 cells/mm³. Annual mean viral loads were reported as suppressed (< 50 copies/mL), low (50-199 copies/mL), or high detectable (≥ 200 copies/mL). The cART regimens were reported yearly.

Results

All CANOC participants were included (n = 13 040). Over the study period, the proportion of individuals with an annual mean CD4 count above 500 cells/mm³ increased from 16.3% to 65.8%, while the proportion of individuals with an undetectable mean viral load increased from 10.6% to 83.2%. As of 2007, the most commonly prescribed 2-agent nucleoside reverse transcriptase inhibitor backbone was tenofovir disoproxil fumarate and emtricitabine. In terms of third agents, non-nucleoside reverse transcriptase inhibitors were the most common class in the periods 2000-2003 and 2014-2015, protease inhibitors were most common in the period 2004-2013, and integrase inhibitors were most common in 2016.

Conclusions

Concordance with treatment guidelines was demonstrated over time with respect to cART prescribing and immunologic and virologic response.

Racial disparity in ART adherence is closed in states with high social trust: Results from the Medical Monitoring Project (MMP), 2015

Racial/ethnic disparities persist in antiretroviral therapy (ART) adherence and viral suppression. We examined associations between state-level social trust and individual-level ART adherence and viral suppression and assessed whether these relationships varied by race/ethnicity. The Medical Monitoring Project (MMP) annually reports nationally representative estimates of the behavioral and clinical characteristics of HIV-positive adults in primary care. A total of 3298 adults diagnosed with HIV between 2015 and 2016 from 16 US states were included. We used weighted logistic regression to model the association between state-level social trust, race/ethnicity (Non-Hispanic Black, White, and Hispanic/Latino), and cross-product interactions with ART adherence (a binary measure derived from three self-reported questions), and viral suppression (a binary measure corresponding to plasma HIV RNA < 200 copies/ml). Social trust was the percentage of people in each state who agreed that most people in their neighborhood could be trusted. A high level of social trust was associated with a higher likelihood of ART adherence (PR [prevalence ratio] = 1.17; 95% confidence interval [CI]: 1.05-1.30). In covariate-adjusted analyses, the association between state-level social trust and individual-level ART adherence significantly varied by race/ethnicity (Wald χ2  F = 9.8 [df = 4], p = 0.044). Social trust was positively associated with ART, but the effect was smaller for Blacks than for Whites (PR = 0.66; 95% CI: 0.57-0.82) in states with the lowest social trust. Black-White differences were closed and no longer significant above mean social trust (PP [predicted probability] = 0.50 vs. 0.53, at two standard deviations). Racial/ethnic disparities in ART adherence were closed among individuals living in states with high social trust. Understanding the mechanisms that promote social trust among neighbors may have downstream impacts on reducing disparities in ART adherence among people with HIV (PWH).

Toward Ending the HIV Epidemic: Temporal Trends and Disparities in Early ART Initiation and Early Viral Suppression Among People Newly Entering HIV Care in the United States, 2012-2018

Background

In 2012, the US Department of Health and Human Services updated their HIV treatment guidelines to recommend antiretroviral therapy (ART) for all people with HIV (PWH) regardless of CD4 count. We investigated recent trends and disparities in early receipt of ART prescription and subsequent viral suppression (VS).

Methods

We examined data from ART-naïve PWH newly presenting to HIV care at 13 North American AIDS Cohort Collaboration on Research and Design clinical cohorts in the United States during 2012-2018. We calculated the cumulative incidence of early ART (within 30 days of entry into care) and early VS (within 6 months of ART initiation) using the Kaplan-Meier survival function. Discrete time-to-event models were fit to estimate unadjusted and adjusted associations of early ART and VS with sociodemographic and clinical factors.

Results

Among 11 853 eligible ART-naïve PWH, the cumulative incidence of early ART increased from 42% in 2012 to 82% in 2018. The cumulative incidence of early VS among the 8613 PWH who initiated ART increased from 83% in 2012 to 93% in 2018. In multivariable models, factors independently associated with delayed ART and VS included non-Hispanic/Latino Black race, residence in the South census region, being a male with injection drug use acquisition risk, and history of substance use disorder (SUD; all P ≤ .05).

Conclusions

Early ART initiation and VS have substantially improved in the United States since the release of universal treatment guidelines. Disparities by factors related to social determinants of health and SUD demand focused attention on and services for some subpopulations.

Suboptimal HIV suppression is associated with progression of coronary artery stenosis: The Multicenter AIDS Cohort Study (MACS) longitudinal coronary CT angiography study

BACKGROUND AND AIMS

People living with HIV (HIV+) are surviving longer due to effective antiretroviral therapy. Cardiovascular disease is a leading cause of non-AIDS related clinical events. We determined HIV-related factors associated with coronary artery stenosis progression.

METHODS

We performed serial coronary CT angiography among HIV+ and HIV-uninfected (HIV-) men in the Multicenter AIDS Cohort Study. The median inter-scan interval was 4.5 years. Stenosis was graded as 0, 1-29, 30-49, 50-69 or ≥70%. Progression was defined as an increase ≥2 categories. Suppressed HIV infection was consistent viral loads <50 copies/mL allowing 1 "blip" <500 copies/mL, otherwise considered viremic. Multivariable Poisson regression analysis assessed adjusted associations between HIV serostatus and viremia with coronary stenosis progression.

RESULTS

The sample included 310 HIV+ (31% viremic) and 234 HIV- men. The median age was 53 years, 30% Black and 23% current smokers. Viremic men were 2.3 times more likely to develop coronary stenosis progression than HIV- men (adjusted RR 2.30; 95% CI, 1.32-4.00, p = 0.003), with no difference in progression between HIV+ suppressed and HIV- men (RR 1.10; 95% CI, 0.70-1.74, p = 0.67). There was a progressive increase in adjusted relative risk with greater viremia (p = 0.03). Men with >1 viral load >500 copies/ml demonstrated greatest stenosis progression (RR 3.01; 95% CI, 1.53-4.92, p = 0.001 compared with HIV- men). Suppressed HIV+ men with suboptimal antiretroviral adherence had greater stenosis progression (RR 1.91; 95% CI 1.12-3.24, p = 0.02) than HIV + suppressed men with optimal adherence.

CONCLUSIONS

Coronary artery stenosis progression was associated with suboptimal HIV RNA suppression and antiretroviral therapy adherence. Effective ongoing HIV virologic suppression and antiretroviral therapy adherence may mitigate risk for coronary disease events among people living with HIV.

The Association Of HIV With Health Care Spending And Use Among Medicare Beneficiaries

An increasingly older population of people with HIV raises concerns about how HIV may influence care for Medicare patients. We therefore sought to determine the extent to which HIV influences additional spending on and use of mental health and medical care among Medicare beneficiaries and, importantly, whether treatment with antiretroviral therapy may reduce this additional spending. Using 2016 Medicare claims, we compared risk-adjusted spending and utilization for Medicare beneficiaries with and without HIV, as well as subgroups of people receiving antiretroviral therapy (ART). Compared to beneficiaries without HIV, those with HIV receiving ART incurred 220.6 percent more spending, mostly driven by ART spending, whereas those with HIV not receiving ART incurred 95.4 percent more spending. Among beneficiaries with HIV, those receiving more months of ART had lower spending on treatment for other chronic conditions relative to those receiving fewer months of ART in a dose-response manner. Beneficiaries with HIV not receiving ART incurred the highest spending related to infections, mental health disorders, and other medical conditions compared to beneficiaries in other HIV subgroups receiving ART for various numbers of months. Our findings suggest that ART may be associated with Medicare Parts A and B savings, but ART adherence and the high prices of HIV drugs in Part D need to be addressed.

Prevalence and Correlates of SARS CoV-2 Among a Community-Based Sample Recruited Using Randomized Venue-Based Sampling. Essex County, NJ, 2020

Disparities in morbidity and mortality related to COVID-19 based on race and ethnicity have been documented in the USA. However, it is unclear if these disparities also exist at the exposure stage. To determine this, studies are needed to document the underlying burden of disease, potential disparities through serologic surveillance. Additionally, such studies can help identify where along the disease spectrum (e.g., exposure, infection, diagnosis, treatment, death) and with regard to the structural factors that necessitate public health and/or clinical interventions. Our objectives in this study were to estimate the true burden of SARS CoV-2 in the community of Essex County, NJ, an early and hard hit area, to determine the correlates of SARS CoV-2 prevalence and to determine if COVID-19 disparities seen by race/ethnicity were also reflected in SARS CoV-2 burden. We utilized venue-based-sampling (VBS) to sample members of the community in Essex County. Participants completed a short electronic survey and provided finger stick blood samples for testing. We sampled 924 residents of Essex County, New Jersey. Testing conducted in this study identified 83 (9.0%) participants as positive for SARS-CoV-2 antibodies. Importantly, our findings suggest that the true burden of SARS-Cov-2 and the pool of persons potentially spreading the virus are slightly more than six times than that suggested by PCR testing Notably, there were no significant differences in odds of testing positive for SARS CoV-2 antibodies in terms of race/ethnicity where we compared Black and Latinx participants to other race participants. Our study suggests that disparities in COVID-19 outcomes stem from potential upstream issues such as underlying conditions, access to testing, and access to care rather than disparities in exposure to the virus.

HIV Treatment Adherence Strategies Among Virally Suppressed Black Sexual Minority Men in Baltimore, Maryland, and Los Angeles, California: A Theory-Based Qualitative Study

ABSTRACT

The goals and strategies of Black sexual minority men living with HIV (BSMMLWH) who achieve viral suppression require further investigation. This study explored treatment adherence strategies among BSMMLWH with sustained viral suppression. We conducted 27 in-depth qualitative interviews with BSMMLWH in Baltimore, Maryland, and Los Angeles, California, between December 2018 and May 2019. Interviews included questions guided by Positive Deviance and Life Course theoretical frameworks regarding multilevel factors and explicit strategies for antiretroviral therapy adherence. Themes regarding intentional, age group-specific strategies such as using technology (among younger men) and taking HIV medications with other daily pills (among older men) were identified. Participants also reported symbiotic goals and values that encouraged adherence, such as having a desire to live, strong familial relationships with clinicians, and support networks. Identifying personal goals and having supportive clinical and social relationships could be key to improving treatment adherence and viral suppression among BSMMLWH.

HIV Treatment Cascade and PrEP Care Continuum Among Serodiscordant Male Couples in the United States

A large proportion of HIV infections among men who have sex with men occur within primary partnerships, however, there is a lack of research focused on serodiscordant male couples. We used baseline data collected as part of Project Stronger Together-a randomized controlled trial to improve treatment outcomes among 155 serodiscordant male couples. We described engagement in HIV care/prevention using the HIV treatment cascade and PrEP care continuum. Among partners living with HIV, 86.5% were linked to care, 77.4% retained in care, 81.3% prescribed ART, 60.7% adherent, and 67.7%virally suppressed. Among HIV-negative partners, 62.6% were willing to take PrEP, 48.4% had ever taken PrEP, and 26.5% were adherent to PrEP. Black partners living with HIV had lower odds of being virally suppressed compared to White partners. Our findings provide evidence to suggest designing programs to address the racial disparities in viral suppression, addressing barriers to HIV prevention/treatment, and improving PrEP education.

Attributing health benefits to preventing HIV infections versus improving health outcomes among people living with HIV: an analysis in six US cities

OBJECTIVE

Combination strategies generate health benefits through improved health outcomes among people living with HIV (PLHIV) and prevention of new infections. We aimed to determine health benefits attributable to improved health among PLHIV versus HIV prevention for a set of combination strategies in six US cities.

DESIGN

A dynamic HIV transmission model.

METHODS

Using a model calibrated for Atlanta, Baltimore, Los Angeles, Miami, New York City (NYC) and Seattle, we assessed the health benefits of city-specific optimal combinations of evidence-based interventions implemented at publicly documented levels and at ideal (90% coverage) scale-up (2020-2030 implementation, 20-year study period). We calculated the proportion of health benefit gains (measured as quality-adjusted life-years) resulting from averted and delayed HIV infections; improved health outcomes among PLHIV; and improved health outcomes due to medication for opioid use disorder (MOUD).

RESULTS

The HIV-specific proportion of total benefits ranged from 68.3% (95% credible interval: 55.3-80.0) in Seattle to 98.5% (97.5-99.3) in Miami, with the rest attributable to MOUD. The majority of HIV-specific health benefits in five of six cities were attributable HIV prevention, and ranged from 33.1% (26.1-41.1) in NYC to 83.1% (79.6-86.6) in Atlanta. Scaling up to ideal service levels resulted in three to seven-fold increases in additional health benefits, mostly from MOUD, with HIV-specific health gains primarily driven by HIV prevention.

CONCLUSION

Optimal combination strategies generated a larger proportion of health benefits attributable to HIV prevention in five of six cities, underlining the substantial benefits of antiretroviral therapy engagement for the prevention of HIV transmission through viral suppression. Understanding to whom benefits accrue may be important in assessing the equity and impact of HIV investments.

Neighborhood Factors Associated with Racial/Ethnic Disparities in Achieving Sustained HIV Viral Suppression Among Miami-Dade County Ryan White Program Clients

Racial/ethnic minorities are disproportionately affected by poor HIV care outcomes. Studies have also examined the effects of neighborhood-level factor on an individual's health outcomes. Thus, the objective of this study was to assess the effects of neighborhood factors on the association between race/ethnicity and sustained viral suppression (all viral load tests <200 copies/mL per year). Data for 6491 people with HIV in the 2017 Miami-Dade County Ryan White Program and neighborhood-level data by ZIP code tabulated areas from the American Community Survey were utilized. Multi-level logistic regression models were used to assess the role of neighborhood factors on the association between race/ethnicity and sustained viral suppression. Results show that non-Hispanic Blacks had lower odds of sustained viral suppression in low socioeconomic disadvantage [adjusted odds ratio (aOR): 0.39; 95% confidence interval (CI): 0.20-0.74], moderate residential instability (aOR: 0.31; 95% CI: 0.15-0.65), and low and high racial/language homogeneity neighborhoods (aOR: 0.38; 95% CI: 0.16-0.88) and (aOR: 0.38; 95% CI: 0.19-0.75), respectively, when compared to non-Hispanic Whites (NHWs). Haitians also exhibited poor outcomes in neighborhoods characterized by moderate residential instability (aOR: 0.42; 95% CI: 0.18-0.97) and high racial/language homogeneity (aOR: 0.49; 95% CI: 0.26-0.93), when compared to NHWs. In conclusion, disparities in rates of sustained viral suppression were observed for racial/ethnic minorities within various neighborhood-level factors. These findings indicate the importance of addressing neighborhood characteristics to achieve optimal care for minorities.

Economic Trends of Racial Disparities in Pediatric Postappendectomy Complications

BACKGROUND

Despite unparalleled advances in perioperative medicine, surgical outcomes remain poor for racial minority patients relative to their white counterparts. Little is known about the excess costs to the health care system related to these disparities.

METHODS

We performed a retrospective analysis of data from the Nationwide Inpatient Sample between 2001 and 2018. We included children younger than 18 years admitted with appendicitis who underwent an appendectomy during their hospital stay. We examined the inflation-adjusted hospital costs attributable to the racial disparities in surgical complications and perforation status, focusing on differences between non-Hispanic white patients and non-Hispanic Black patients.

RESULTS

We included 100 639 children who underwent appendectomy, of whom 89.9% were non-Hispanic white and 10.1% were non-Hispanic Black. Irrespective of perforation status at presentation, surgical complications were consistently higher for Black compared with white children, with no evidence of narrowing of the racial disparity gap over time. Black children consistently incurred higher hospital costs (median difference: $629 [95% confidence interval: $500-$758; P < .01). The total inflation-adjusted hospital costs for Black children were $518 658 984, and $59 372 044 (11.41%) represented the excess because of the racial disparities in perforation rates.

CONCLUSIONS

Although all patients had a progressive decline in post appendectomy complications, Black children consistently had higher rates of complications and perforation, imposing a significant economic burden. We provide an empirical economic argument for sustained efforts to reduce racial disparities in pediatric surgical outcomes, notwithstanding that eliminating these disparities is simply the right thing to do.

Improving health equity and ending the HIV epidemic in the USA: a distributional cost-effectiveness analysis in six cities

BACKGROUND

In the USA, Black and Hispanic or Latinx individuals continue to be disproportionately affected by HIV. Applying a distributional cost-effectiveness framework, we estimated the cost-effectiveness and epidemiological impact of two combination implementation approaches to identify the approach that best meets the dual objectives of improving population health and reducing racial or ethnic health disparities.

METHODS

We adapted a dynamic, compartmental HIV transmission model to characterise HIV micro-epidemics in six US cities: Atlanta, Baltimore, Los Angeles, Miami, New York, and Seattle. We considered combinations of 16 evidence-based interventions to diagnose, treat, and prevent HIV transmission according to previously documented levels of scale-up. We then identified optimal combination strategies for each city, with the distribution of each intervention implemented according to existing service levels (proportional services approach) and the racial or ethnic distribution of new diagnoses (between Black, Hispanic or Latinx, and White or other ethnicity individuals; equity approach). We estimated total costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios of strategies implemented from 2020 to 2030 (health-care perspective; 20-year time horizon; 3% annual discount rate). We estimated three measures of health inequality (between-group variance, index of disparity, Theil index), incidence rate ratios, and rate differences for the selected strategies under each approach.

FINDINGS

In all cities, optimal combination strategies under the equity approach generated more QALYs than those with proportional services, ranging from a 3·1% increase (95% credible interval [CrI] 1·4-5·3) in New York to more than double (101·9% [75·4-134·6]) in Atlanta. Compared with proportional services, the equity approach delivered lower costs over 20 years in all cities except Los Angeles; cost reductions ranged from $22·9 million (95% CrI 5·3-55·7 million) in Seattle to $579·8 million (255·4-940·5 million) in Atlanta. The equity approach also reduced incidence disparities and health inequality measures in all cities except Los Angeles.

INTERPRETATION

Equity-focused HIV combination implementation strategies that reduce disparities for Black and Hispanic or Latinx individuals can significantly improve population health, reduce costs, and drive progress towards Ending the HIV Epidemic goals in the USA.

Differences in HIV clinical outcomes amongst heterosexuals in the United Kingdom by ethnicity

OBJECTIVE

We investigated differences in clinical outcomes in heterosexual participants, by ethnicity in the UK Collaborative HIV Cohort Study from 2000 to 2017.

DESIGN

Cohort analysis.

METHODS

Logistic/proportional hazard regression assessed ethnic group differences in CD4+ cell count at presentation, engagement-in-care, combination antiretroviral therapy (cART) initiation, viral suppression and rebound.

RESULTS

Of 12 302 participants [median age: 37 (interquartile range: 31-44) years, 52.5% women, total follow-up: 85 846 person-years], 64.4% were black African, 19.1% white, 6.3% black Caribbean, 3.6% black other, 3.3% South Asian/other Asian and 3.4% other/mixed. CD4+ cell count at presentation amongst participants from non-white groups were lower than the white group. Participants were engaged-in-care for 79.6% of follow-up time; however, black and other/mixed groups were less likely to be engaged-in-care than the white group (adjusted odds ratios vs. white: black African: 0.70 (95% confidence interval (CI) 0.63-0.79], black Caribbean: 0.74 (0.63-0.88), other/mixed: 0.78 (0.62-0.98), black other: 0.81 (0.64-1.02)). Of 8867 who started cART, 79.1% achieved viral suppression, with no differences by ethnicity in cART initiation or viral suppression. Viral rebound (22.2%) was more common in the black other [1.95 (1.37-2.77)], black African [1.85 (1.52-2.24)], black Caribbean [1.73 (1.28-2.33)], South Asian/other Asian [1.35 (0.90-2.03)] and other/mixed [1.09 (0.69-1.71)] groups than in white participants.

CONCLUSION

Heterosexual people from black, Asian and minority ethnic (BAME) groups presented with lower CD4+ cell counts, spent less time engaged-in-care and were more likely to experience viral rebound than white people. Work to understand and address these differences is needed.

Mortality Among Persons Entering HIV Care Compared With the General U.S. Population : An Observational Study

BACKGROUND

Understanding advances in the care and treatment of adults with HIV as well as remaining gaps requires comparing differences in mortality between persons entering care for HIV and the general population.

OBJECTIVE

To assess the extent to which mortality among persons entering HIV care in the United States is elevated over mortality among matched persons in the general U.S. population and trends in this difference over time.

DESIGN

Observational cohort study.

SETTING

Thirteen sites from the U.S. North American AIDS Cohort Collaboration on Research and Design.

PARTICIPANTS

82 766 adults entering HIV clinical care between 1999 and 2017 and a subset of the U.S. population matched on calendar time, age, sex, race/ethnicity, and county using U.S. mortality and population data compiled by the National Center for Health Statistics.

MEASUREMENTS

Five-year all-cause mortality, estimated using the Kaplan-Meier estimator of the survival function.

RESULTS

Overall 5-year mortality among persons entering HIV care was 10.6%, and mortality among the matched U.S. population was 2.9%, for a difference of 7.7 (95% CI, 7.4 to 7.9) percentage points. This difference decreased over time, from 11.1 percentage points among those entering care between 1999 and 2004 to 2.7 percentage points among those entering care between 2011 and 2017.

LIMITATION

Matching on available covariates may have failed to account for differences in mortality that were due to sociodemographic factors rather than consequences of HIV infection and other modifiable factors.

CONCLUSION

Mortality among persons entering HIV care decreased dramatically between 1999 and 2017, although those entering care remained at modestly higher risk for death in the years after starting care than comparable persons in the general U.S. population.

Understanding Technology Fit Among People with HIV Based on Intersections of Race, Sex, and Sexual Behavior: An Equitable Approach to Analyzing Differences Across Multiple Social Identities

HIV disproportionately impacts individuals based on intersecting categories (e.g. gender, race/ethnicity, behavior), with groups most at-risk deemed priority populations. Using weighted effects coding to account for differential group sizes, this study used multilevel mixed logistic models to investigate differences in eHealth use and willingness to use eHealth for HIV-related information among priority populations. Compared to the sample average, Black men who had sex with women were less likely to use all technologies except cellphones with text-messaging and less likely to be willing to use computers and tablets. White and Hispanic men who had sex with men were more likely to use all technologies. No significant differences existed for use or willingness to use cellphones with text-messaging. Future research should consider approaches used here to account for equity and multiple intersecting social identities; practitioners may use these findings or similar local data to ensure fit between eHealth programs and priority populations.

A Rapid Review of Disparities in HIV Prevention and Care Outcomes Among Hispanic/Latino Men Who Have Sex With Men in the United States

In the United States, Hispanic/Latino men who have sex with men (HLMSM) are disproportionally affected by HIV. We conducted a rapid review of national surveillance data to examine disparities in HIV prevention and care outcomes among HLMSM. Thirteen reports provided relevant data from 2011 to 2018. Compared to White MSM, a higher percentage of HIV-negative HLMSM reported not taking PrEP and engaging in condomless sex; a lower percentage of HIV-negative HLMSM at risk for HIV reported PrEP awareness and use; and a lower percentage of HIV-positive HLMSM were aware of their status, linked to HIV care, and virally suppressed. Viral suppression rates in HLMSM were better among Ryan White clients than the national rates, suggesting that access to comprehensive care/services reduces disparities. Findings also call for identifying individual, social, and structural factors contributing to condomless sex without PrEP use and HIV status unawareness and identifying best approaches for scaling up comprehensive care/services.

HIV mortality across the 30 largest U.S. cities: assessing overall trends and racial inequities

BACKGROUND

Despite decreases in overall HIV mortality in the U.S., large racial inequities persist. Most previous analyses of HIV mortality and mortality inequities have utilized national- or state-level data.

METHODS

Using vital statistics mortality data and American Community Survey population estimates, we calculated HIV mortality rates and Black:White HIV mortality rate ratios (RR) for the 30 most populous U.S. cities at two time points, 2010-2014 (T1) and 2015-2019 (T2).

RESULTS

Almost all cities (28) had HIV mortality rates higher than the national rate at both time points. At T2, HIV mortality rates ranged from 0.8 per 100,000 (San Jose, CA) to 15.2 per 100,000 (Baltimore, MD). Across cities, Black people were approximately 2-8 times more likely to die from HIV compared to White people at both time points. Over the decade, these racial disparities decreased at the national level (T1: RR = 11.0, T2: RR = 9.8), and in one city (Charlotte, NC).

DISCUSSION

We identified large geographic and racial inequities in HIV mortality in U.S. urban areas. These city-specific data may motivate change in cities and can help guide city leaders and other health advocates as they implement, test, and support policies and programming to decrease HIV mortality.

A Concept Mapping Study to Understand Multilevel Resilience Resources Among African American/Black Adults Living with HIV in the Southern United States

Resilience may help people living with HIV (PLWH) overcome adversities to disease management. This study identifies multilevel resilience resources among African American/Black (AA/B) PLWH and examines whether resilience resources differ by demographics and neighborhood risk environments. We recruited participants and conducted concept mapping at two clinics in the southeastern United States. Concept Mapping incorporates qualitative and quantitative methods to represent participant-generated concepts via two-dimensional maps. Eligible participants had to attend ≥ 75% of their scheduled clinic appointments and did not have ≥ 2 consecutive detectable HIV-1 viral load measurements in the past 2 years. Of the 85 AA/B PLWH who were invited, forty-eight participated. Twelve resilience resource clusters emerged-five individual, two interpersonal, two organizational/policy and three neighborhood level clusters. There were strong correlations in cluster ratings for demographic and neighborhood risk environment comparison groups (r ≥ 0.89). These findings could inform development of theories, measures and interventions for AA/B PLWH.

Research Synthesis, HIV Prevention Response, and Public Health: CDC's HIV/AIDS Prevention Research Synthesis Project

OBJECTIVE

Research synthesis, through qualitative or quantitative systematic reviews, allows for integrating results of primary research to improve public health. We examined more than 2 decades of work in HIV prevention by the Centers for Disease Control and Prevention's (CDC's) HIV/AIDS Prevention Research Synthesis (PRS) Project. We describe the context and contributions of research synthesis, including systematic reviews and meta-analyses, through the experience of the PRS Project.

METHODS

We reviewed PRS Project publications and products and summarized PRS contributions from 1996 to July 2020 in 4 areas: synthesis of interventions and epidemiologic studies, synthesis methods, prevention programs, and prevention policy.

RESULTS

PRS Project publications summarized risk behaviors and effects of prevention interventions (eg, changing one's perception of risk, teaching condom negotiation skills) across populations at risk for HIV infection and intervention approaches (eg, one-on-one or group meetings) as the HIV/AIDS epidemic and science evolved. We used the PRS Project cumulative database and intervention efficacy reviews to contribute to prevention programs and policies through identification of evidence-based interventions and development of program guidance. Subject matter experts and scientific evidence informed PRS Project products and contributions, which were implemented through strategic programmatic partnerships.

CONCLUSIONS

The contributions of the PRS Project to HIV prevention and public health efforts in the United States can be credited to CDC's long-standing support of the project and its context within a federal prevention agency, where HIV programs and policies were developed and implemented. The effect of the PRS Project was likely facilitated by opportunities to directly influence program and policy because of connections with other research translation activities and program and policy decision making within CDC.

Disparities in Care Outcomes in Atlanta Between Black and White Men Who Have Sex With Men Living With HIV: Protocol for a Prospective Cohort Study (Engage[men]t)

BACKGROUND

The US HIV epidemic is driven by infections in men who have sex with men and characterized by profound disparities in HIV prevalence and outcomes for Black Americans. Black men who have sex with men living with HIV are reported to have worse care outcomes than other men who have sex with men, but the reasons for these health inequities are not clear. We planned a prospective observational cohort study to help understand the reasons for worse HIV care outcomes for Black versus White men who have sex with men in Atlanta.

OBJECTIVE

The aim of this study is to identify individual, dyadic, network, neighborhood, and structural factors that explain disparities in HIV viral suppression between Black and White men who have sex with men living with HIV in Atlanta.

METHODS

Black and White men who have sex with men living with HIV were enrolled in a prospective cohort study with in-person visits and viral suppression assessments at baseline, 12 months, and 24 months; additional surveys of care and risk behaviors at 3, 6, and 18 months; analysis of care received outside the study through public health reporting; and qualitative interviews for participants who experienced sentinel health events (eg, loss of viral suppression) during the study. The study is based on the Bronfenbrenner socioecological theoretical model.

RESULTS

Men who have sex with men (n=400) were enrolled between June 2016 and June 2017 in Atlanta. Follow-up was completed in June 2019; final study retention was 80% at 24 months.

CONCLUSIONS

Health disparities for Black men who have sex with men are hypothesized to be driven by structural racism and barriers to care. Observational studies are important to document and quantify the specific factors within the socioecological framework that account for disparities in viral suppression. In the meantime, it is also critical to push for steps to improve access to care, including Medicaid expansion in Southern states, such as Georgia, which have not yet moved to expand Medicaid.

Viral Rebound Among Persons With Diagnosed HIV Who Achieved Viral Suppression, United States

BACKGROUND

Some persons who achieve viral suppression may later experience viral rebound, potentially putting them at risk for transmitting HIV. We estimate the prevalence of, and describe factors associated with, viral rebound among adults with diagnosed HIV in the United States who had ≥2 viral load tests in a 12-month period.

SETTING

The Medical Monitoring Project is an annual cross-sectional survey about the experiences and needs of adults with diagnosed HIV sampled from the National HIV Surveillance System.

METHODS

We analyzed interview and medical record data from 3 Medical Monitoring Project cycles spanning June 2015-May 2018. We analyzed viral load results from the 12-month period before the interview among persons with ≥2 viral load tests who achieved viral suppression. Data were weighted based on known probabilities of selection, adjusted for patient nonresponse, and poststratified to known population totals from the National HIV Surveillance System.

RESULTS

Among those with ≥2 viral load tests who achieved viral suppression, 7.5% demonstrated viral rebound. In multivariable analyses, viral rebound was higher among non-Hispanic blacks, persons ages 18-39, persons with public insurance, persons recently experiencing homelessness, persons with higher numbers of viral load tests, persons who missed HIV care appointments, and persons with suboptimal adherence to antiretroviral therapy.

CONCLUSIONS

Viral rebound varied by sociodemographic and clinical characteristics. HIV providers can monitor persons at greatest risk for viral rebound and link patients with ancillary services or evidence-based interventions to help them remain virally suppressed. Our findings can inform strategies and interventions implemented under the Ending the HIV Epidemic initiative.

Added Benefits of Pre-Exposure Prophylaxis Use on HIV Incidence with Minimal Changes in Efficiency in the Context of High Treatment Engagement Among Men Who Have Sex with Men

Although there is ongoing debate over the need for substantial increases in pre-exposure prophylaxis (PrEP) use when antiretroviral treatment confers the dual benefits of reducing HIV-related morbidity and mortality and the risk of HIV transmission, no studies to date have quantified the potential added benefits of PrEP use and changes in its efficiency in the context of high treatment engagement across multiple US subpopulations. We used a previously published agent-based model to simulate HIV transmission in a dynamic network of Black/African American and White men who have sex with men (MSM) in Atlanta, Georgia (2015-2024) to understand how reductions in HIV incidence attributable to varying levels of PrEP use change when United Nations Joint Programme on HIV/AIDS (UNAIDS) "90-90-90" goals for HIV treatment are achieved and maintained. Even at achievement of "90-90-90" goals, 75% PrEP coverage further reduced incidence by 67.9% and 74.2% to 1.53 [simulation interval (SI): 1.39-1.70] and 0.355 (SI: 0.316-0.391) per 100 person-years for Black/African American and White MSM, respectively, compared with the same scenario with no PrEP use. Increasing PrEP coverage from 15% to 75% under "90-90-90" goals only increased the number of person-years of PrEP use per infection averted by 8.1% and 10.5% to 26.7 (SI: 25.6-28.0) and 73.3 (SI: 70.6-75.7) among Black/African American MSM and White MSM, respectively. Even with high treatment engagement, substantial expansion of PrEP use contributes to meaningful decreases in HIV incidence among MSM with minimal changes in efficiency.

ART Adherence Among Men Who Have Sex with Men Living with HIV: Key Challenges and Opportunities

PURPOSE OF REVIEW

In the USA, gay, bisexual, and other men who have sex with men (MSM) are disproportionately affected by HIV. High levels of adherence to antiretroviral therapy (ART) can dramatically improve outcomes for persons living with HIV and reduce the risk of HIV transmission to others. Yet, there are numerous individual, social, and structural barriers to optimal ART adherence. Many of these factors disproportionately impact Black MSM and may contribute to their poorer rates of ART adherence. This review synthesizes the key challenges and intervention opportunities to improve ART adherence among MSM in the USA.

RECENT FINDINGS

Key challenges to ART adherence include stigma, violence, depression, and substance use. Black MSM are significantly disadvantaged by several of these factors. There are several promising interventions to improve ART adherence among MSM, and there remains an opportunity to culturally tailor these to the needs of Black MSM populations to enhance adherence. Despite high rates of HIV among MSM, there continues to be a paucity of research on the various contributors to poor ART adherence among this population. Similarly, few interventions have been tested that lead to increased and sustained ART adherence among Black MSM.

Modeling an integrated HIV prevention and care continuum to achieve the Ending the HIV Epidemic goals

OBJECTIVE

We sought to evaluate, which combinations of HIV prevention and care activities would have the greatest impact towards reaching the US Ending the HIV Epidemic (EHE) plan goals of HIV incidence reduction.

DESIGN

A stochastic network-based HIV transmission model for men who have sex with men (MSM), calibrated to surveillance estimates in the Atlanta area, a focal EHE jurisdiction.

METHODS

Model scenarios varied HIV screening rates under different assumptions of how HIV-negative MSM would be linked to PrEP initiation, and rates of HIV care linkage and retention for those screening positive.

RESULTS

A ten-fold relative increase in HIV screening rates (to approximately biannual screening for black and Hispanic MSM and quarterly for white MSM) would lead to 43% of infections averted if integrated with PrEP initiation. Improvements focused only on black MSM would achieve nearly the same outcome (37% of infections averted). Improvements to HIV care retention would avert 41% of infections if retention rates were improved ten-fold. If both screening and retention were jointly improved ten-fold, up to 74% of cumulative infections would be averted. Under this scenario, it would take 4 years to meet the 75% EHE goal and 12 years to meet the 90% goal for Atlanta MSM.

CONCLUSION

Reaching the EHE 75% incidence reduction goals by their target dates will require immediate and substantial improvements in HIV screening, PrEP, and ART care retention. Meeting these EHE goals in target jurisdictions like Atlanta will be possible only by addressing the HIV service needs of black MSM.

Socio-Structural and Neighborhood Predictors of Incident Criminal Justice Involvement in a Population-Based Cohort of Young Black MSM and Transgender Women

Black men who have sex with men (MSM) and transgender women are disproportionately affected by criminal justice involvement (CJI) and HIV. This study recruited 618 young Black MSM and transgender women in Chicago, IL, using respondent-driven sampling between 2013 and 2014. Random effects logistic regression evaluated predictors of incident CJI over 18 months of follow-up. Controlling for respondent age, gender and sexual identity, spirituality (aOR 0.56, 95% CI 0.33-0.96), and presence of a mother figure (aOR 0.41, 95% CI 0.19-0.89) were protective against CJI. Economic hardship (financial or residential instability vs. neither aOR 2.23, 95% CI 1.10-4.51), two or more past episodes of CJI vs. none (aOR 2.66, 95% CI 1.40-5.66), and substance use (marijuana use vs. none aOR 2.79, 95% CI 1.23-6.34; other drug use vs. none aOR 4.49, 95% CI 1.66-12.16) were associated with CJI during follow-up. Research to identify and leverage resilience factors that can buffer the effects of socioeconomic marginalization may increase the effectiveness of interventions to address the socio-structural factors that increase the risk for CJI among Black MSM and transgender women. Given the intersection of incarceration, HIV and other STIs, and socio-structural stressors, criminal justice settings are important venues for interventions to reduce health inequities in these populations.

Brief Report: Racial and Ethnic Disparities in Sustained Viral Suppression and Transmission Risk Potential Among Persons Aged 13-29 Years Living With Diagnosed HIV Infection, United States, 2016

BACKGROUND

In 2016, persons aged 13-29 years represented 23.1% of the US population, yet accounted for 41.7% of HIV diagnoses. Racial/ethnic minorities are disproportionally affected by HIV. Sustaining viral suppression helps persons living with diagnosed HIV infection (PLWDH) stay healthy and reduces the risk of transmitting HIV. We examined racial/ethnic disparities in sustained viral suppression and transmission risk potential among PLWDH aged 13-29 years.

METHODS

We analyzed data from the National HIV Surveillance System reported through December 2018 from 42 jurisdictions with complete laboratory reporting. We included persons aged 13-29 years who received an HIV diagnosis by December 31, 2015, most recently resided in one of the 42 jurisdictions, and were alive at the end of 2016. Sustained viral suppression was defined as viral load <200 copies/mL for all tests in 2016. Transmission risk potential was estimated using the number of days with viral loads >1500 copies/mL.

RESULTS

Of the 90,812 PLWDH aged 13-29 years included in the analysis, 41.5% had sustained viral suppression in 2016. Across age, sex, and most transmission categories, blacks had the lowest prevalence of sustained viral suppression. Among the 28,154 who were in care but without sustained viral suppression, the average number of days with viral load >1500 copies/mL was 206 days (56.4% of the 12-month period).

CONCLUSIONS

Sustained viral suppression was suboptimal and transmission risk potential was high for PLWDH aged 13-29 years. Racial/ethnic disparities were apparent, calling for strengthening tailored interventions to improve care outcomes.

Egocentric sexual networks of men who have sex with men in the United States: Results from the ARTnet study

In this paper, we present an overview and descriptive results from one of the first egocentric network studies of men who have sex with men (MSM) from across the United States: the ARTnet study. ARTnet was designed to support prevention research for human immunodeficiency virus (HIV) and other sexually transmitted infections (STIs) that are transmitted across partnership networks. ARTnet implemented a population-based egocentric network study design that sampled egos from the target population and asked them to report on the number, attributes, and timing of their sexual partnerships. Such data provide the foundation needed for parameterizing stochastic network models that are used for disease projection and intervention planning. ARTnet collected data online from 2017 to 2019, with a final sample of 4904 participants who reported on 16198 sexual partnerships. The aims of this paper were to characterize the joint distribution of three network parameters needed for modeling: degree distributions, assortative mixing, and partnership age, with heterogeneity by partnership type (main, casual and one-time), demography, and geography. Participants had an average of 1.19 currently active partnerships ("mean degree"), which was higher for casual partnerships (0.74) than main partnerships (0.45). The mean rate of one-time partnership acquisition was 0.16 per week (8.5 partners per year). Main partnerships lasted 272.5 weeks on average, while casual partnerships lasted 133.0 weeks. There was strong but heterogenous assortative mixing by race/ethnicity for all groups. The mean absolute age difference for all partnership types was 9.5 years, with main partners differing by 6.3 years compared to 10.8 years for casual partners. Our analysis suggests that MSM may be at sustained risk for HIV/STI acquisition and transmission through high network degree of sexual partnerships. The ARTnet network study provides a robust and reproducible foundation for understanding the dynamics of HIV/STI epidemiology among U.S. MSM and supporting the implementation science that seeks to address persistent challenges in HIV/STI prevention.

Brief Report: Clinical Outcomes of Young Black Men Receiving HIV Medical Care in the United States, 2009-2014

BACKGROUND

More than one-quarter of 2016 HIV diagnoses among blacks in the United States occurred among persons aged 15-24 years, and three-quarters were among men. Although the prevalence of viral suppression in all tests in the past 12 months (durable viral suppression) among persons receiving HIV care increased from 58% to 68% during 2009-2013, we do not know whether this same improvement was observed among young black men receiving care.

METHODS

We analyzed the 2009-2014 Medical Monitoring Project data collected from 336 black men aged 18-24 years. We estimated the proportion of young black men receiving HIV care who were prescribed antiretroviral therapy (ART), adherent to ART, and durably virally suppressed. We assessed changes in clinical outcomes over time and their association with patient characteristics, health behaviors, and depression.

RESULTS

During 2009-2014, 80% of young black men receiving HIV care were prescribed ART, 73% were adherent to ART, and 36% had durable viral suppression. There was no significant change in viral suppression over this period. ART prescription and durable viral suppression were significantly higher among those receiving the Ryan White HIV/AIDS Program assistance compared with those who did not. Durable viral suppression was significantly lower among those who used drugs compared with those who did not.

CONCLUSIONS

Viral suppression among young black men during 2009-2014 was lower than that among the overall population receiving HIV care in 2013 (36% vs. 68%). Increasing viral suppression is essential to improve health and reduce HIV transmissions in this key population.

Effects of Reaching National Goals on HIV Incidence, by Race and Ethnicity, in the United States

CONTEXT

Human immunodeficiency virus (HIV) incidence and prevalence in the United States are characterized by significant disparities by race/ethnicity. National HIV care goals, such as boosting to 90% the proportion of persons whose HIV is diagnosed and increasing to 80% the proportion of persons living with diagnosed HIV who are virally suppressed, will likely reduce HIV incidence, but their effects on HIV-related disparities are uncertain.

OBJECTIVE

We sought to understand by race/ethnicity how current HIV care varies, the level of effort required to achieve national HIV care goals, and the effects of reaching those goals on HIV incidence and disparities.

DESIGN

Using a dynamic model of HIV transmission, we identified 2016 progress along the HIV care continuum among blacks, Hispanics, and whites/others compared with national 2020 goals. We examined disparities over time.

SETTING

United States.

PARTICIPANTS

Beginning in 2006, our dynamic compartmental model simulated the sexually active US population 13 to 64 years of age, which was stratified into 195 subpopulations by transmission group, sex, race/ethnicity, age, male circumcision status, and HIV risk level.

MAIN OUTCOME MEASURE

We compared HIV cumulative incidence from 2016 to 2020 when goals were reached compared with base case assumptions about progression along the HIV care continuum.

RESULTS

The 2016 proportion of persons with diagnosed HIV who were on treatment and virally suppressed was 50% among blacks, 56% among Hispanics, and 61% among whites/others, compared with a national goal of 80%. When diagnosis, linkage, and viral suppression goals were reached in 2020, cumulative HIV incidence fell by 32% (uncertainty range: 18%-37%) for blacks, 25% (22%-31%) for Hispanics, and 25% (21%-28%) for whites/others. Disparity measures changed little.

CONCLUSIONS

Achieving national HIV care goals will require different levels of effort by race/ethnicity but likely will result in substantial declines in cumulative HIV incidence. HIV-related disparities in incidence and prevalence may be difficult to resolve.

Emotional Communication in HIV Care: An Observational Study of Patients' Expressed Emotions and Clinician Response

Emotional support is essential to good communication, yet clinicians often miss opportunities to provide empathy to patients. Our study explores the nature of emotional expressions found among patients new to HIV care, how HIV clinicians respond to these expressions, and predictors of clinician responses. Patient-provider encounters were audio-recorded, transcribed, and coded using the VR-CoDES. We categorized patient emotional expressions by intensity (subtle 'cues' vs. more explicit 'concerns'), timing (initial vs. subsequent), and content (medical vs. non-medical). Emotional communication was present in 65 of 91 encounters. Clinicians were more likely to focus specifically on patient emotion for concerns versus cues (OR 4.55; 95% CI 1.36, 15.20). Clinicians were less likely to provide space when emotional expressions were repeated (OR 0.32; 95% CI 0.14, 0.77), medically-related (OR 0.36; 95% CI 0.17, 0.77), and from African American patients (OR 0.42; 95% CI 0.21, 0.84). Potential areas for quality improvement include raising clinician awareness of subtle emotional expressions, the emotional content of medically-related issues, and racial differences in clinician response.

Racial and Ethnic Differences in Viral Suppression Among HIV-Positive Women in Care

BACKGROUND

Women with HIV diagnoses are less likely to be virally suppressed than men. Women of different racial/ethnic groups may be differentially affected by sociodemographic factors. We examined differences in viral suppression among women by race/ethnicity and associated variables to inform prevention interventions.

METHODS

We used data from the 2010-2014 cycles of the Medical Monitoring Project, a cross-sectional survey of HIV-positive adults in care. We limited analyses to black, Hispanic, and white women. We calculated weighted prevalences of recent viral suppression (undetectable or <200 copies/mL) and sustained viral suppression (consistent viral suppression during the past 12 months) among women by race/ethnicity. We computed adjusted prevalence differences (aPDs) and 95% confidence intervals (CIs) for viral suppression by racial/ethnic group, controlling for selected variables, including available social determinants of health variables.

RESULTS

Among women, 62.9% were black, 19.8% Hispanic, and 17.3% white. Overall, 74.3% had recent viral suppression, and 62.3% had sustained viral suppression. Compared with white women (79.7%, CI: 77.2 to 82.2), black (72.5%, CI: 70.3 to 74.7; PD: 7.2) and Hispanic (75.4%, CI: 72.6 to 78.3; PD: 4.3) women were less likely to have recent viral suppression. In multivariable analyses, after adjusting for antiretroviral therapy adherence, HIV disease stage, age, homelessness, and education, black-white aPDs remained significant for recent (aPD: 4.8, CI: 1.6 to 8.1) and sustained (aPD: 5.0, CI: 1.1 to 9.0) viral suppression.

CONCLUSION

Viral suppression was suboptimal for all women, but more for black and Hispanic women. Differences between black, Hispanic, and white women may be partially due to antiretroviral therapy adherence, HIV disease stage, and social determinants of health factors.

HIV Coinfection Among Persons Diagnosed As Having Sexually Transmitted Diseases, San Francisco, 2007 to 2014

BACKGROUND

Early syphilis, gonorrhea, and chlamydia but not HIV infections have increased in San Francisco, primarily among men.

METHODS

We linked records of persons reported with early syphilis, gonorrhea, and chlamydia to records of persons reported with HIV to measure the proportion and characteristics of San Francisco residents with HIV-sexually transmitted disease (STD) coinfection between 2007 and 2014. We measured trends in HIV coinfection separately for men and women for each STD.

RESULTS

From 2007 to 2014, of the 5745 early syphilis, 18,037 gonorrhea, and 37,224 chlamydia diagnoses that were reported, 66%, 28%, and 15%, respectively, were among persons coinfected with HIV. Men accounted for most persons with early syphilis, gonorrhea, and chlamydia HIV coinfection. For early syphilis and HIV coinfection, among men who have sex with men (MSM), Latinos were more likely and Asian/Pacific Islanders were less likely to have HIV coinfection compared with whites. Older age at diagnosis and history of an STD were both also significantly associated with early syphilis and HIV coinfection. Transgender persons, older ages, Latino MSM compared with white MSM, and those with a history of STD were more likely to have HIV coinfection, whereas Asian/Pacific Islander MSM were less likely to have HIV coinfection for both gonorrhea and chlamydia, CONCLUSIONS: Our findings highlight the high burden of HIV-STD coinfection in San Francisco. To maintain the current declines in HIV incidence and turn the curve in rising STD incidence, there is an urgent need for collaborative HIV and STD prevention and control efforts.

Longitudinal virological outcomes and factors associated with virological failure in behaviorally HIV-infected young adults on combination antiretroviral treatment in the Netherlands, 2000 to 2015

Achieving and maintaining viral suppression in young adults (18-24 years) living with HIV is challenging. Overall HIV viral suppression rates are lower in young as compared to older adults. Longitudinal data provide valuable insight on dynamics of viral suppression and variables of potential influence on HIV virological failure (VF), but is scarce in young adults living with HIV on combination antiretroviral therapy (cART). We evaluated longitudinal virological outcomes of behaviorally young adults (18-24 years) living with HIV in the Netherlands over a period of 15 years.We analyzed data from the Dutch national HIV database of 816 young adults living with HIV on cART in the Netherlands from 2000 to 2015. VF was defined as 2 consecutive detectable plasma HIV-1 viral load (VL) measurements > 200 copies/ml. Generalized linear mixed model analyses were used to assess HIV VF over time and identify risk factors associated with VF.VF during the study follow-up occurred at least once in 26% of cases. The probability of experiencing VF decreased over the study period per calendar year (OR 0.78, 95% confidence interval [CI];0.72; 0.85). Factors significantly associated with VF were being infected through heterosexual contact (OR 5.20, CI 1.39;19.38) and originating from Latin America or the Caribbean (OR 6.59, CI 2.08;20.92). Smaller, yet significant risk factors for VF were being infected through a blood transfusion or a needle accident (OR9.93, CI 1.34;73.84, and having started with cART with a nadir CD4 count >500 cells/μl (OR 11.36, CI 2.03;63.48).In our large cohort of young adults, the risk of VF has diminished over 15 years. Specific subgroups were identified to be at risk for suboptimal treatment.

HIV-Related Stigma and Viral Suppression Among African-American Women: Exploring the Mediating Roles of Depression and ART Nonadherence

We used baseline data from a sample of African-American women living with HIV who were recruited to participate in a stigma-reduction intervention in Chicago and Birmingham (2013-2015) to (1) evaluate the relationship between HIV-related stigma and viral suppression, and (2) assess the role of depression and nonadherence to antiretroviral therapy (ART) as mediators. Data from women were included in this secondary analysis if they were on ART, had viral load data collected within 8-weeks of study entry and had complete covariate data. We used logistic regression to estimate the total effect of HIV-related stigma (14-item Stigma Scale for Chronic Illness) on viral suppression (< 200 copies/mL), and serial mediation analysis to estimate indirect effects mediated by depressive symptoms (8-item Patient Health Questionnaire) and ART nonadherence (number of days with missed doses). Among 100 women who met study inclusion criteria, 95% reported some level of HIV-related stigma. In adjusted models, higher levels of HIV-related stigma were associated with lower odds of being virally suppressed (AOR = 0.93, 95% CI = 0.89-0.98). In mediation analysis, indirect effects through depression and ART nonadherence were not significant. Findings suggest that HIV-related stigma is common among African-American women living with HIV, and those who experience higher levels of stigma are less likely to be virally suppressed. However, the mechanisms remain unclear.

Healthcare facility characteristics associated with achievement and maintenance of HIV viral suppression among persons newly diagnosed with HIV in New York City

Health care facility characteristics have been shown to influence intermediary health outcomes among persons with HIV, but few longitudinal studies of suppression have included these characteristics. We studied the association of these characteristics with the achievement and maintenance of HIV viral suppression among New York City (NYC) residents aged 13 years and older newly diagnosed with HIV between 2006 and 2012. The NYC HIV surveillance registry provided individual and facility data (N = 12,547 persons). Multivariable proportional hazards models estimated the likelihood of individual achievement and maintenance of suppression by type of facility, patient volume, and distance from residence, accounting for facility clustering and for individual-level confounders. Viral suppression was achieved within 12 months by 44% and at a later point by another 29%. Viral suppression occurred at a lower rate in facilities with low HIV patient volume (e.g., 10-24 diagnoses per year vs. ≥75, adjusted hazard ratio [AHR] = 0.87, 95% confidence interval [CI] 0.79-0.95) and in screening/diagnosis sites (vs. hospitals, AHR = 0.86, 95% CI 0.80-0.92). Among persons achieving viral suppression, 18% experienced virologic failure within 12 months and 24% later. Those receiving care at large outpatient facilities or large private practices had a lower rate of virologic failure (e.g., large outpatient facilities vs. large hospitals, AHR = 0.63, 95% CI 0.53-0.75). Achievement and maintenance of viral suppression were associated with facilities with higher HIV-positive caseloads. Some facilities with small caseloads and screening/diagnosis sites may need stronger care or referral systems to help persons with HIV achieve and maintain viral suppression.
