Retention in HIV Care and Viral Suppression: Individual- and Neighborhood-Level Predictors of Racial/Ethnic Differences, Florida, 2015

The Impact of HIV-Related Stigma on Racial/Ethnic Disparities in Retention in HIV Care Among Adults Living with HIV in Florida

BACKGROUND

Our study examines the effects of distinct HIV stigma subtypes on retention in care and racial-ethnic differences among persons with HIV (PWH).

METHODS

Using Florida Medical Monitoring Project 2015-2017 data, we analyzed patients' clinical and behavioral characteristics. We analyzed 89,889 PWH in Florida (50.0% non-Hispanic Blacks, 20.8% Hispanics, 29.2% non-Hispanic whites). HIV stigma subtypes, negative self-image, anticipated stigma, personalized stigma, and retention in care were examined with logistic regressions.

RESULTS

People with high negative self-image and anticipated stigma were less likely to be retained (CI: 0.84-0.92; 0.47-0.53). The association between HIV-related stigma subtypes and retention in care differed between Black, White, and Hispanic participants. Negative self-image was associated with higher retention rates among Hispanics (CI: 5.64-9.26) and Whites (CI: 1.04-1.27), while low retention rates among Blacks (0.617-0.686). The likelihood of staying in care was lower across all racial-ethnic groups when the anticipated stigma was high or moderate. In contrast, personalized stigma increased retention across all racial-ethnic groups.

CONCLUSION

Results showed that distinct types of HIV stigma differentially impact retention, and these associations differ by race and ethnicity. Future interventions should address the effect HIV stigma subtypes have on racially minoritized PWH retention.

Population Density and Health Outcomes in Women with HIV in the Southern United States: A Retrospective Longitudinal Analysis

Purpose: Published studies have revealed challenges for people with human immunodeficiency virus (HIV) living in rural areas compared to those in urban areas, such as poor access to HIV care, insufficient transportation, and isolation. The purpose of this study was to examine associations between population density and multiple psychosocial and clinical outcomes in the largest cohort of women with HIV (WWH) in the United States. Methods: Women's Interagency HIV Study (WIHS) participants from Southern sites (n = 561) in 2013-2018 were categorized and compared by population density quartiles. The most urban quartile was compared with the most rural quartile in several psychosocial and clinical variables, including HIV viral load suppression, HIV medication adherence, HIV care attendance, depression, internalized HIV stigma, and perceived discrimination in healthcare settings. Results: Although women in the lowest density quartile were unexpectedly more highly resourced, women in that quartile had greater odds of not attending an HIV care visit in the last six months (odds ratio [OR] = 0.64, 95% confidence interval [CI] [0.43-0.95]), yet higher odds for having fully suppressed HIV when compared to women in the highest density quartile (OR = 1.64, 95% CI [1.13-2.38]). Highly urban WWH had greater likelihood of unsuppressed HIV, even after controlling for income, employment, and health insurance, despite reporting greater HIV care adherence and similar medication adherence. Discussion: Further investigation into the reasons for these disparities by population density is needed, and particular clinical attention should be focused on individuals from high population density areas to help maximize their health outcomes.

Socio-Behavioural Barriers to Viral Suppression in the Older Adult Population in Rural South Africa

South Africa has the largest share of people living with HIV in the world and this population is ageing. The social context in which people seek HIV care is often ignored. Apart from clinical interventions, socio-behavioural factors impact successful HIV care outcomes for older adults living with HIV. We use cross-sectional data linked with demographic household surveillance data, consisting of HIV positive adults aged above 40, to identify socio-behavioural predictors of a detectable viral load. Older adults were more likely to have a detectable viral load if they did not disclose their HIV positive status to close family members (aOR 2.56, 95% CI 1.89-3.46), resided in the poorest households (aOR 1.98, 95% CI 1.23-3.18), or were not taking medications other than ART (aOR 1.83, 95% CI 1.02-1.99) likely to have a detectable. Clinical interventions in HIV care must be supported by understanding the socio-behavioural barriers that occur outside the health facility. The importance of community health care workers in bridging this gap may offer more optimum outcomes for older adults ageing with HIV.

St. Louis Enhancing Engagement and Retention in HIV/AIDS Care (STEER): a participatory intersectional needs assessment for intervention and implementation planning

Background Missouri is one of seven priority states identified by the Ending the HIV Epidemic Initiative, and St. Louis contains almost half of the people living with HIV (PLWH) in Missouri. As St. Louis has a marked history of structural racism and economic inequities, we utilized the Intersectionality Based Policy Analysis (IBPA) framework to guide a participatory needs assessment for planning and program development. Methods The planning team included researchers, the lead implementer from our community partner, and two community representatives, and had biweekly 60-90 minute meetings for 18 months. The planning team discussed and approved all research materials, reviewed and interpreted results, and made decisions about outreach, recruitment, conduct of the needs assessment and development of the planned intervention. The needs assessment integrated information from existing data, (1) interviews with (a) PLWH (n=12), (b) community leaders (n=5), (c) clinical leaders (n=4), and (d) community health workers (CHWs) (n=3) and (e) CHW supervisors (n=3) who participated in a Boston University-led demonstration project on CHWs in the context of HIV and (2) focus groups (2 FG, 12 participants) with front line health workers such as peer specialists, health coaches and outreach workers. A rapid qualitative analysis approach was used for all interviews and focus groups. Results The IBPA was used to guide team discussions of team values, definition and framing of the problem, questions and topics in the key informant interviews, and implementation strategies. Applying the IBPA framework contributed to a focus on intersectional drivers of inequities in HIV services. The effective management of HIV faces significant challenges from high provider turnover, insufficient integration of CHWs into care teams, and organizational limitations in tailoring treatment plans. Increasing use of CHWs for HIV treatment and prevention also faces challenges. People living with HIV (PLWH) encounter multiple barriers such as stigma, lack of social support, co-morbidities, medication side effects and difficulties in meeting basic needs. Conclusions Addressing intersectional drivers of health inequities may require multi-level, structural approaches. We see the IBPA as a valuable tool for participatory planning while integrating community engagement principles in program and implementation design for improving HIV outcomes.

Providing telemedicine services to persons living with HIV in an urban community: a demonstration project

Although HIV incidence and mortality rates have declined over the past 20 years, HIV health disparities continue to persist among patients living in urban communities. Barriers to proficient health outcomes for persons with HIV (PWH) in urban communities include lack of access to care, resulting from limited transportation or clinic availability. While healthcare systems in rural communities provide telemedicine (TM) services to PWH to eliminate transportation and accessibility barriers, few examples exist regarding TM use for PWH in urban communities. This project's goal was to increase the provision of healthcare services in an urban setting to PWH, using TM. As guided by "Integration of Healthcare Delivery Service" theories and key principles, we created an integration framework comprised of several simultaneous, overlapping activities to include: (1) capacity building (2) clinical standardization (3) community and patient engagement and (4) evaluation performance and measurements. This paper describes major activities involved with developing, implementing and evaluating a TM program for PWH. We discuss results, challenges, and lessons learned from integrating this program into our existing healthcare system.

Spatial and temporal analysis of HIV clinical outcomes in Florida reveals counties with persistent racial and ethnic disparities during 2012-2019

BACKGROUND

Racial/ethnic disparities in the HIV care continuum have been well documented in the US, with especially striking inequalities in viral suppression rates between White and Black persons with HIV (PWH). The South is considered an epicenter of the HIV epidemic in the US, with the largest population of PWH living in Florida. It is unclear whether any disparities in viral suppression or immune reconstitution-a clinical outcome highly correlated with overall prognosis-have changed over time or are homogenous geographically. In this analysis, we 1) investigate longitudinal trends in viral suppression and immune reconstitution among PWH in Florida, 2) examine the impact of socio-ecological factors on the association between race/ethnicity and clinical outcomes, 3) explore spatial and temporal variations in disparities in clinical outcomes.

METHODS

Data were obtained from the Florida Department of Health for 42,369 PWH enrolled in the Ryan White program during 2008-2020. We linked the data to county-level socio-ecological variables available from County Health Rankings. GEE models were fit to assess the effect of race/ethnicity on immune reconstitution and viral suppression longitudinally. Poisson Bayesian hierarchical models were fit to analyze geographic variations in racial/ethnic disparities while adjusting for socio-ecological factors.

RESULTS

Proportions of PWH who experienced viral suppression and immune reconstitution rose by 60% and 45%, respectively, from 2008-2020. Odds of immune reconstitution and viral suppression were significantly higher among White [odds ratio =2.34, 95% credible interval=2.14-2.56; 1.95 (1.85-2.05)], and Hispanic [1.70 (1.54-1.87); 2.18(2.07-2.31)] PWH, compared with Black PWH. These findings remained unchanged after accounting for socio-ecological factors. Rural and urban counties in north-central Florida saw the largest racial/ethnic disparities.

CONCLUSIONS

There is persistent, spatially heterogeneous, racial/ethnic disparity in HIV clinical outcomes in Florida. This disparity could not be explained by socio-ecological factors, suggesting that further research on modifiable factors that can improve HIV outcomes among Black and Hispanic PWH in Florida is needed.

Factors Associated With Antiretroviral Adherence Among Youth Living With HIV

BACKGROUND

Youth living with HIV (YLH) have an increased risk for psychosocial stressors that can affect their antiretroviral (ARV) adherence. We examined factors associated with self-reported ARV adherence among YLH ages 12-24 years old.

SETTING

YLH (N = 147) were recruited in Los Angeles, CA, and New Orleans, LA from 2017 to 2020.

METHODS

YLH whose self-reported recent (30 days) ARV adherence was "excellent" or "very good" were compared with nonadherent YLH on sociodemographic, clinical, and psychosocial factors using univariate and multivariate analyses.

RESULTS

Participants were predominantly male (88%), and 81% identified as gay, bisexual, transgender, queer, or other. The mean duration on ARV was 27 months (range 0-237 months). Most YLH (71.2%) self-reported being adherent, and 79% of those who self-reported adherence were also virally suppressed (<200 copies/mL). Multivariate analysis indicated being adherent was significantly associated with white race [aOR = 8.07, confidence intervals (CI): 1.45 to 74.0], Hispanic/Latinx ethnicity [aOR = 3.57, CI: 1.16 to 12.80], more social support [aOR = 1.11, CI: 1.05 to 1.18], and being on ARV for a shorter duration [aOR = 0.99, CI: 0.97 to 0.99]. Mental health symptoms, substance use, age, and history of homelessness or incarceration were unrelated to adherence.

CONCLUSIONS

Enhancing efforts to provide support for adherence to non-white youth, and those with limited social support and who have been on ARV treatment longer, may help increase viral suppression among YLH.

Neighborhood characteristics and HIV treatment outcomes: A scoping review

Recognizing challenges faced by people living with HIV is vital for improving their HIV treatment outcomes. While individual-level interventions play a crucial role, community factors can shape the impact of individual interventions on treatment outcomes. Understanding neighborhood characteristics' association with HIV treatment outcomes is crucial for optimizing effectiveness. This review aims to summarize the research scope on the association between neighborhood characteristics and HIV treatment outcomes. The databases PubMed, CINAHL (EBSCOhost), Embase (Elsevier), and PsychINFO (EBSCOhost) were searched from the start of each database to Nov 21, 2022. Screening was performed by three independent reviewers. Full-text publications of all study design meeting inclusion criteria were included in the review. There were no language or geographical limitations. Conference proceedings, abstract only, and opinion reports were excluded from the review. The search yielded 7,822 publications, 35 of which met the criteria for inclusion in the review. Studies assessed the relationship between neighborhood-level disadvantage (n = 24), composition and interaction (n = 17), social-economic status (n = 18), deprivation (n = 16), disorder (n = 8), and rural-urban status (n = 7) and HIV treatment outcomes. The relationship between all neighborhood characteristics and HIV treatment outcomes was not consistent across studies. Only 7 studies found deprivation had a negative association with HIV treatment outcomes; 6 found that areas with specific racial/ethnic densities were associated with poor HIV treatment outcomes, and 5 showed that disorder was associated with poor HIV treatment outcomes. Three studies showed that rural residence was associated with improved HIV treatment outcomes. There were inconsistent findings regarding the association between neighborhood characteristics and HIV treatment outcomes. While the impact of neighborhood characteristics on disease outcomes is highly recognized, there is a paucity of standardized definitions and metrics for community characteristics to support a robust assessment of this hypothesis. Comparative studies that define and assess how specific neighborhood indicators independently or jointly affect HIV treatment outcomes are highly needed.

Systematic Review of Neighborhood Factors Impacting HIV Care Continuum Participation in the United States

Social determinants have been increasingly implicated in accelerating HIV vulnerability, particularly for disenfranchised communities. Among these determinants, neighborhood factors play an important role in undermining HIV prevention. However, there has been little research comprehensively examining the impact of neighborhood factors on HIV care continuum participation in the US. To address this, we conducted a systematic review (PROSPERO registration number CRD42022359787) to determine neighborhood factors most frequently associated with diminished HIV care continuum participation. Peer-reviewed studies were included if published between 2013 - 2022, centralized in the US, and analyzed a neighborhood factor with at least one aspect of the HIV care continuum. The review was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. Study quality was guided by LEGEND (Let Evidence Guide Every New Decision) evaluation guidelines. Systematic review analysis was conducted using Covidence software. There were 3,192 studies identified for initial screening. Forty-four were included for review after eliminating duplicates, title/abstract screening, and eligibility assessment. Social and economic disenfranchisement of neighborhoods negatively impacts HIV care continuum participation among persons living with HIV. In particular, five key neighborhood factors (socioeconomic status, segregation, social disorder, stigma, and care access) were associated with challenged HIV care continuum participation. Race moderated relationships between neighborhood quality and HIV care continuum participation. Structural interventions addressing neighborhood social and economic challenges may have favorable downstream effects for improving HIV care continuum participation.

Estimation of place-based vulnerability scores for HIV viral non-suppression: an application leveraging data from a cohort of people with histories of using drugs

The relationships between place (e.g., neighborhood) and HIV are commonly investigated. As measurements of place are multivariate, most studies apply some dimension reduction, resulting in one variable (or a small number of variables), which is then used to characterize place. Typical dimension reduction methods seek to capture the most variance of the raw items, resulting in a type of summary variable we call "disadvantage score". We propose to add a different type of summary variable, the "vulnerability score," to the toolbox of the researchers doing place and HIV research. The vulnerability score measures how place, as known through the raw measurements, is predictive of an outcome. It captures variation in place characteristics that matters most for the particular outcome. We demonstrate the estimation and utility of place-based vulnerability scores for HIV viral non-suppression, using data with complicated clustering from a cohort of people with histories of injecting drugs.

Racial Disparities in Access to the Kidney Transplant Waitlist Among People with Human Immunodeficiency Virus

The epidemiology of human immunodeficiency virus (HIV) has shifted such that Black individuals disproportionately represent incident HIV diagnoses. While risk of end-stage kidney disease (ESKD) among people with HIV (PWH) has declined with effective antiretroviral therapies, a substantial racial disparity in ESKD burden exists with the greatest prevalence among Black PWH. Disparities in waitlisting for kidney transplantation, the optimal treatment for ESKD, exist for both PWH and Black individuals without HIV, but it is unknown whether these characteristics together exacerbate such disparities. Six hundred two thousand six ESKD patients were identified from the United States Renal Data System (January 1, 2007 to December 31, 2017), and HIV-status was determined through Medicare claims. Cox proportional hazards regression was used to determine waitlisting rates. Multiplicative interaction terms between HIV-status and race were examined. The 6250 PWH were significantly younger, more commonly Black, and less commonly female than those without HIV. HIV-status and race were independently associated with 50% and 12% lower likelihood of waitlisting, respectively [adjusted hazard ratio (aHR): 0.50, 95% confidence interval (CI): 0.36-0.69, p < 0.001; aHR: 0.88, 95% CI: 0.87-0.90, p < 0.001]. There was also a significant interaction present between HIV-status and Black race (aHR: 0.80, 95% CI: 0.66-0.98, p < 0.001) such that, while HIV-status and Black race were independently associated with decreased waitlisting, the interaction of Black race and HIV-status exacerbated those disparities. While limited by lack of HIV-specific data that may impact inferences with respect to race, additional studies are urgently needed to understand the interplay between HIV risk factors, HIV-stigma, and racism, and how intersectionality may exacerbate disparities in transplantation among PWH.

Relationships Between Patient Race and Residential Race Context With Missed Human Immunodeficiency Virus Care Visits in the United States, 2010-2015

BACKGROUND

Racial inequities exist in retention in human immunodeficiency virus (HIV) care and multilevel analyses are needed to contextualize and address these differences. Leveraging data from a multisite clinical cohort of people with HIV (PWH), we assessed the relationships between patient race and residential characteristics with missed HIV care visits.

METHODS

Medical record and patient-reported outcome (PRO; including mental health and substance-use measures) data were drawn from 7 participating Center for AIDS Research Network of Integrated Clinical Systems (CNICS) sites including N = 20 807 PWH from January 2010 through December 2015. Generalized estimating equations were used to account for nesting within individuals and within census tracts in multivariable models assessing the relationship between race and missed HIV care visits, controlling for individual demographic and health characteristics and census tract characteristics.

RESULTS

Black PWH resided in more disadvantaged census tracts, on average. Black PWH residing in census tracts with higher proportion of Black residents were more likely to miss an HIV care visit. Non-Black PWH were less likely to miss a visit regardless of where they lived. These relationships were attenuated when PRO data were included.

CONCLUSIONS

Residential racial segregation and disadvantage may create inequities between Black PWH and non-Black PWH in retention in HIV care. Multilevel approaches are needed to retain PWH in HIV care, accounting for community, healthcare setting, and individual needs and resources.

Predictive Modeling of Lapses in Care for People Living with HIV in Chicago: Algorithm Development and Interpretation

BACKGROUND

Reducing care lapses for people living with HIV is critical to ending the HIV epidemic and beneficial for their health. Predictive modeling can identify clinical factors associated with HIV care lapses. Previous studies have identified these factors within a single clinic or using a national network of clinics, but public health strategies to improve retention in care in the United States often occur within a regional jurisdiction (eg, a city or county).

OBJECTIVE

We sought to build predictive models of HIV care lapses using a large, multisite, noncurated database of electronic health records (EHRs) in Chicago, Illinois.

METHODS

We used 2011-2019 data from the Chicago Area Patient-Centered Outcomes Research Network (CAPriCORN), a database including multiple health systems, covering the majority of 23,580 people with an HIV diagnosis living in Chicago. CAPriCORN uses a hash-based data deduplication method to follow people across multiple Chicago health care systems with different EHRs, providing a unique citywide view of retention in HIV care. From the database, we used diagnosis codes, medications, laboratory tests, demographics, and encounter information to build predictive models. Our primary outcome was lapses in HIV care, defined as having more than 12 months between subsequent HIV care encounters. We built logistic regression, random forest, elastic net logistic regression, and XGBoost models using all variables and compared their performance to a baseline logistic regression model containing only demographics and retention history.

RESULTS

We included people living with HIV with at least 2 HIV care encounters in the database, yielding 16,930 people living with HIV with 191,492 encounters. All models outperformed the baseline logistic regression model, with the most improvement from the XGBoost model (area under the receiver operating characteristic curve 0.776, 95% CI 0.768-0.784 vs 0.674, 95% CI 0.664-0.683; P<.001). Top predictors included the history of care lapses, being seen by an infectious disease provider (vs a primary care provider), site of care, Hispanic ethnicity, and previous HIV laboratory testing. The random forest model (area under the receiver operating characteristic curve 0.751, 95% CI 0.742-0.759) revealed age, insurance type, and chronic comorbidities (eg, hypertension), as important variables in predicting a care lapse.

CONCLUSIONS

We used a real-world approach to leverage the full scope of data available in modern EHRs to predict HIV care lapses. Our findings reinforce previously known factors, such as the history of prior care lapses, while also showing the importance of laboratory testing, chronic comorbidities, sociodemographic characteristics, and clinic-specific factors for predicting care lapses for people living with HIV in Chicago. We provide a framework for others to use data from multiple different health care systems within a single city to examine lapses in care using EHR data, which will aid in jurisdictional efforts to improve retention in HIV care.

Virological failure and adherence to antiretroviral therapy in adolescents and young adults living with human immunodeficiency virus

OBJECTIVE

HIV (human immunodeficiency virus) infection remains a major public health challenge. Infected young people at any age are less likely to adhere to care in a timely manner and to maintain a suppressed VL. This review aims to identify factors associated with virologic failure and adherence to drug therapy in adolescents and young adults (10-24 years) living with HIV.

METHODS

Systematic review using the PubMed and Virtual Health Library databases and including articles published between 2009 and 2021. Data were analysed in six categories: individual factors, pharmacological/therapy-related aspects, factors related to HIV/acquired immunodeficiency syndrome (AIDS) infection, HIV/AIDS stigma, social support and health system/services. The study's protocol was registered on the PROSPERO platform (CRD42020167581).

RESULTS

A total of 19,819 articles were found in the initial search and 31 studies were included in this systematic review. Most studies were carried out on the African continent. Male sex, alcohol use, low education, adverse effects of medication, lack of social support, stigma related to HIV/AIDS, need for transportation to access the health service and forgetfulness were linked to poor adherence to therapy. Good adherence was achieved with sufficient nutrition, good social support, greater confidence in the use of therapy and fewer ART side effects. Low levels of CD4, alcohol use, substance abuse, low education, non-adherence to medication and forgetfulness were linked to virological failure.

CONCLUSION

Individual, social and structural factors constitute barriers to adherence to ART among adolescent and young adults. It is necessary to know the difficulties related to the use of therapy to work out specific strategies that create conditions to improve medication adherence and viral suppression, reducing the levels of virological failure in this population.

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.

Moderation effect of community health on the relationship between racial/ethnic residential segregation and HIV viral suppression in South Carolina: A county-level longitudinal study from 2013 to 2018

Background

Viral suppression is the ultimate goal of the HIV treatment cascade and a primary endpoint of antiretroviral therapy. Empirical evidence found racial/ethnic disparities in viral suppression among people living with HIV (PWH), but the evidence of the relationship between racial/ethnic residential segregation and place-based viral suppression is scarce. Further exploring potential structural moderators in this relationship has substantial implications for healthcare policymaking and resource allocation. The current study aimed to investigate the spatial-temporal disparities in the HIV viral suppression rate across 46 counties in South Carolina from 2013 to 2018. We also examined the impact of racial/ethnic residential segregation and the moderation effect of community health, one measurement of community engagement and volunteerism.

Methods

The proportion of PWH who achieved viral suppression for each county and calendar year was calculated using de-identified electronic medical records. The isolation index was calculated and used to measure racial/ethnic residential segregation. The community health index and other county-level factors were directly extracted from multiple publicly available datasets. We used geospatial mapping to explore the spatial-temporal variations of HIV viral suppression rates. Hierarchical quasi-binominal regression models were used to examine the impacts of racial/ethnic residential segregation on county-level viral suppression rate by the extent of community health.

Results

From 2013 to 2018, the average viral suppression rate across 46 counties in SC increased from 64.3% to 65.4%. Regression results revealed that counties with high racial/ethnic residential segregation were more likely to have a low viral suppression rate (β = -0.56, 95% CI: -0.75 to -0.37). In counties with high levels of community health, the impact of racial/ethnic residential segregation on viral suppression rate decreased as compared with those with low levels of community health (β = 5.50, 95% CI: 0.95-10.05).

Conclusions

Racial/ethnic residential segregation acts as a structural barrier to placed-based viral suppression rates and compromises the goal of the HIV treatment cascade. Concentrated and sustained county-level interventions aiming to improve community health can be practical approaches to promote health equity in HIV treatment and care.

Post-immigration factors affecting retention in HIV care and viral suppression in Latin American and Caribbean immigrant populations in the United States: a systematic review

OBJECTIVES

To reduce disparities in HIV care outcomes among Latin American and Caribbean (LAC) immigrants living with HIV in the U.S., it is necessary to identify factors influencing HIV care in this population. A systematic review that provides a comprehensive understanding of factors influencing retention in HIV care and viral suppression among LAC immigrants living with HIV in the U.S. is lacking. This systematic review used the Immigrant Health Services Utilization theoretical framework to provide an understanding of these factors.

DESIGN

We searched for peer-reviewed publications in MEDLINE, EMBASE, CINAHL, PsycINFO, and ASSIA, from January 1996 to June 2020.

RESULTS

A total of 17 qualitative (n = 10) and quantitative (n = 7) studies were included in the review. The most commonly reported general and immigrant-specific factors appearing in studies were undocumented immigration status, HIV stigma, homophobia, cultural norms, values and beliefs, family and social support, language barriers, structure, complexity and quality of the U.S. healthcare delivery system, and patient-provider relationship.

CONCLUSION

These findings highlight the importance of considering immigrant-specific factors along with general factors to improve the provision of HIV care services and HIV care outcomes among LAC immigrant populations.

Longitudinal trajectories of HIV care engagement since diagnosis among persons with HIV in the Florida Ryan White program

HIV care engagement is a dynamic process. We employed group-based trajectory modeling to examine longitudinal patterns in care engagement among people who were newly diagnosed with HIV and enrolled in the Ryan White program in Florida (n = 9,755) between 2010 and 2015. Five trajectories were identified (47.9% "in care" with 1-2 care visit(s) per 6 months, 18.0% "frequent care" with 3 or more care visits per 6 months, 11.0% "re-engage", 11.0% "gradual drop out", 12.6% "early dropout") based on the number of care attendances (including outpatient/case management visits, viral load or CD4 test) for each six-month during the first five years since diagnosis. Relative to "in care", people in the "frequent care" trajectory were more likely to be Hispanic/Latino and older at HIV diagnosis, whereas people in the three suboptimal care retention trajectories were more likely to be younger. Area deprivation index, rurality, and county health rankings were also strongly associated with care trajectories. Individual- and community-level factors associated to the three suboptimal care retention trajectories, if confirmed to be causative and actionable, could be prioritized to improve HIV care engagement.

Multicenter Development and Validation of a Model for Predicting Retention in Care Among People with HIV

Predictive analytics can be used to identify people with HIV currently retained in care who are at risk for future disengagement from care, allowing for prioritization of retention interventions. We utilized machine learning methods to develop predictive models of retention in care, defined as no more than a 12 month gap between HIV care appointments in the Center for AIDS Research Network of Integrated Clinical Systems (CNICS) cohort. Data were split longitudinally into derivation and validation cohorts. We created logistic regression (LR), random forest (RF), and gradient boosted machine (XGB) models within a discrete-time survival analysis framework and compared their performance to a baseline model that included only demographics, viral suppression, and retention history. 21,267 Patients with 507,687 visits from 2007 to 2018 were included. The LR model outperformed the baseline model (AUC 0.68 [0.67-0.70] vs. 0.60 [0.59-0.62], P < 0.001). RF and XGB models had similar performance to the LR model. Top features in the LR model included retention history, age, and viral suppression.

Social disorganization and new HIV diagnoses, 2013-2017, Florida: Rural-urban differences

PURPOSE

To compare the role of neighborhood social disorganization factors on human immunodeficiency virus (HIV) diagnosis rates in urban and rural areas in Florida, we conducted an ecologic study of HIV diagnosis rates during 2013-2017 and social disorganization components, including concentrated disadvantage, ethnic heterogeneity, and residential instability.

METHODS

Indices of social disorganization components were obtained from principal component analyses of American Community Survey variables for 910 postal codes. Rural/urban classification was based on the United States Department of Agriculture Rural Urban Commuting Area codes. Using multivariable linear regression, the relationship between social disorganization indices and HIV diagnosis rates was assessed.

FINDINGS

The only social disorganization index that was significantly higher in rural than urban areas was concentrated disadvantage. In rural areas, the concentrated disadvantage index was significantly associated with HIV diagnosis rates (P = .007) when controlling for the other social disorganization factors but was no longer significant after additionally controlling for prevalence of people with an HIV diagnosis who were not virally suppressed. In urban areas, even after controlling for prevalence of people with HIV who were not virally suppressed, lower male-to-female population ratios and higher scores of residential instability, concentrated disadvantage, and LatinX/immigrant density indices were associated with higher HIV diagnosis rates (all P < .01).

CONCLUSIONS

In addition to improving community levels of viral suppression, the community contextual environment, including the rurality of the environment, needs to be considered in strategies to end the HIV epidemic in the United States.

Baseline and Process Factors of Anti-Retroviral Therapy That Predict Loss to Follow-up Among People Living with HIV/AIDS in China: A Retrospective Cohort Study

We explored the predictors and predictive models of loss to follow-up (LTFU) during the first year of anti-retroviral therapy (ART). LTFU was defined as the failure to visit the clinic for antiretroviral drugs for ≥ 90 days after the last missed scheduled visit. Based on the electronic medical records of 5953 patients who were HIV positive and began ART between 2016 and 2019 in China, the LTFU rate was 7.24 (95% confidence interval 6.49-7.97) per 100 person-years during the first year of ART. ART baseline factors were associated with LTFU, but were non-optimal predictors. A model including ART process-related factors such as follow-up behaviors and physical health status had an area under the receiver operating characteristic curve of 73.4% for predicting LTFU. Therefore, the medical records of follow-up visits can be used to identify patients with a high risk of LTFU and allow interventions to be implemented proactively.

Multilevel Analysis of Individual and Neighborhood Characteristics Associated with Viral Suppression Among Adults with HIV in Rio de Janeiro, Brazil

Understanding the impact of neighborhood context on viral suppression outcomes may help explain health disparities and identify future interventions. We assessed the relationship between individual characteristics, neighborhood socioeconomic context, and viral suppression using multilevel logistic regression models. Adults with HIV initiating antiretroviral therapy (ART) between 2000 and 2017, who resided in Rio de Janeiro and had an HIV-1 RNA level (viral load) measured 90-270 days after ART initiation were included. Overall, 83.9% achieved viral suppression. Participants who were older, had a higher level of education, and identified as heterosexual cisgender men and cisgender men-who-have-sex-with-men had increased odds of viral suppression. Later calendar year of ART initiation carried the strongest association with viral suppression, reflecting the increased effectiveness and tolerability of ART over time. Neighborhood socioeconomic indicators did not predict viral suppression in unadjusted or adjusted analyses, which may result from the integrated care provided in our health care facility together with Brazil's universal treatment.

Substance Use Predicts Sustained Viral Suppression in a Community Cohort of Sexual and Gender Minority Youth Living with HIV

Retention in care and sustained viral suppression are integral outcomes in the care continuum for people living with HIV (PLWH) and HIV prevention; however, less is known about how substance use predicts sustained viral suppression over time. This study seeks to examine the predictive effects of substance use on sustained viral suppression in a sample of cisgender sexual minority men and gender minority PLWH (n = 163) drawn from a longitudinal sample in the Chicago area collected 2015-2019. Using data from 3 visits separated by 6 months, participants were coded persistently detectable, inconsistently virally suppressed, and consistently virally suppressed (< 40 copies/mL at all visits). Multinomial logistic regressions were utilized. About 40% of participants had sustained viral suppression. In multinomial logistic regressions, CUDIT-R predicted persistent detectable status and stimulant use was associated with inconsistent viral suppression. Substance use may create challenges in achieving sustained viral suppression, which has important implications for care and prevention.

Factors Associated with Viral Suppression Among Racial/Ethnic Minority Women in the Miami-Dade County Ryan White Program, 2017

The study's objective was to identify factors associated with differences in the rate of viral suppression among minority women with HIV/AIDS in care in the Miami-Dade County Ryan White Program (RWP). A retrospective cohort study was conducted using social characteristics and laboratory data of minority women enrolled in the Miami-Dade County RWP in 2017. Viral suppression was defined as <200 copies/mL using the last viral load test of 2017. Multilevel logistic regression models were used to estimate adjusted odds ratio (aOR) and 95% confidence intervals (CIs). Of the 1,550 racial/ethnic minority women in the study population, 43.1% were African American, 31.3% were Hispanic, and 25.6% were Haitian. The proportion of women virally suppressed was lower among African Americans (80.8%) than among Hispanics (86.4%) and Haitians (85.1%). Viral suppression rates were significantly lower among women aged 18-34 years (aOR: 0.41, CI: 0.27-0.64) and 35-49 years (0.63, 0.45-0.90) vs. ≥50 years, born in the United States (0.48, 0.30-0.78), having a household income of <100% the federal poverty level (0.54, 0.30-0.95), previously diagnosed with AIDS (0.60, 0.44-0.81), reporting problematic drug use (0.23, 0.08-0.69), and living in a residentially unstable neighborhood (0.77, 0.64-0.93). Race/ethnicity was not associated with viral suppression after adjusting for other factors. Factors associated with lack of viral suppression were similar among minority racial/ethnic groups. Interventions at the individual level focusing on young, U.S. born individuals, and those who report drug use, and at the neighborhood level for those living in residentially unstable neighborhoods are needed to improve viral suppression outcomes.

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.

Latent Class Analysis of Syndemic Factors Associated with Sustained Viral Suppression among Ryan White HIV/AIDS Program Clients in Miami, 2017

The study's objective was to identify the association between sustained viral suppression (all viral load tests < 200 copies/ml per year) and patterns of co-occurring risk factors including, mental health, substance use, sexual risk behavior, and adverse social conditions for people with HIV (PWH). Latent class analysis followed by multivariable logistic regression was conducted for 6554 PWH in the Miami-Dade County Ryan White Program during 2017, and a five-class model was selected. Compared to Class 1 (no risk factors), the odds of achieving sustained viral suppression was significantly lower for Class 2 (mental health) (aOR: 0.67; 95% CI 0.54-0.83), Class 3 (substance use and multiple sexual partners) (0.60; 0.47-0.76), Class 4 (substance use, multiple sexual partners, and domestic violence) (0.71; 0.55-0.93), and Class 5 (mental health, substance use, multiple sexual partners, domestic violence, and homelessness) (0.26; 0.19-0.35). Findings indicate the need for targeted interventions that address these syndemic factors.

Applying a machine learning modelling framework to predict delayed linkage to care in patients newly diagnosed with HIV in Mecklenburg County, North Carolina, USA

BACKGROUND

Machine learning has the potential to help researchers better understand and close the gap in HIV care delivery in large metropolitan regions such as Mecklenburg County, North Carolina, USA.

OBJECTIVES

We aim to identify important risk factors associated with delayed linkage to care for HIV patients with novel machine learning models and identify high-risk regions of the delay.

METHODS

Deidentified 2013-2017 Mecklenburg County surveillance data in eHARS format were requested. Both univariate analyses and machine learning random forest model (developed in R 3.5.0) were applied to quantify associations between delayed linkage to care (>30 days after diagnosis) and various risk factors for individual HIV patients. We also aggregated linkage to care by zip codes to identify high-risk communities within the county.

RESULTS

Types of HIV-diagnosing facility significantly influenced time to linkage; first diagnosis in hospital was associated with the shortest time to linkage. HIV patients with lower CD4+ cell counts (<200/ml) were twice as likely to link to care within 30 days than those with higher CD4+ cell count. Random forest model achieved high accuracy (>80% without CD4+ cell count data and >95% with CD4+ cell count data) to predict risk of delay in linkage to care. In addition, we also identified top high-risk zip codes of delayed linkage.

CONCLUSION

The findings helped public health teams identify high-risk communities of delayed HIV care continuum across Mecklenburg County. The methodology framework can be applied to other regions with HIV epidemic and challenge of delayed linkage to care.

Psychosocial Factors and the Care Cascade for Hepatitis C Treatment Colocated at a Syringe Service Program

BACKGROUND

Direct-acting antiviral (DAA) therapy for hepatitis C virus (HCV) is highly effective. However, people who inject drugs face significant barriers to DAA access.

METHODS

We describe a program that colocates HCV management within a syringe service program in New York City. We performed a retrospective chart review of all patients with confirmed HCV viremia.

RESULTS

From 2015 to 2018, 102 patients with viremia completed intake. Fifty-eight patients started DAAs. Nine patients discontinued treatment or were lost to follow-up before completion; 1 is continuing DAA treatment. Of 48 patients who completed therapy, sustained virologic response (SVR) was achieved in 43 (89.6%). Age and established mental health treatment at intake were associated with SVR. Regular cocaine use was negatively associated with SVR in univariate analysis, but this association was not significant after adjustment for age. Of 30 patients completing DAA therapy with active illicit opioid use at intake, 14 (46.4%) engaged in opioid use disorder (OUD) treatment during therapy, and 9 remained in OUD treatment after completion of DAA treatment.

CONCLUSIONS

Loss to follow-up is a challenge for people who inject drugs, but among those who completed treatment, SVR was achieved at a high rate. Mental health treatment may facilitate HCV cure. Conversely, HCV therapy may facilitate engagement in OUD treatment and other services.

Associations between population density and clinical and sociodemographic factors in women living with HIV in the Southern United States

To explore the associations of urbanicity with clinical/behavioral outcomes and sociodemographic factors among women living with HIV in the Southern United States, 523 participants of the Women's Interagency HIV Study were classified into population density quartiles. Rural-Urban Commuting Area codes revealed that 7% resided in areas where >30% commute to urban areas, 2% resided in small towns or rural areas, and 91% resided in varying densities of urban areas. Although women in lower density, mostly suburban areas reported higher socioeconomic indicators such as advanced education and greater annual household income, larger proportions of women in the lowest density quartile perceived discrimination in health care settings and agreed with several internalized HIV stigma scale items. Women in the lower quartiles had higher CD4 counts, while those in the lowest quartile were more likely to have a suppressed HIV viral load, report being employed, and not report a history of drug use or current heavy alcohol use. More research is needed to understand the interplay between population density and mechanisms contributing to HIV control as well as increased internalized stigma and perceived discrimination, along with how to target interventions to improve outcomes for individuals with HIV across urban, suburban, and rural areas.

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.

Enacted HIV-Related Stigma's Association with Anxiety & Depression Among People Living with HIV (PLWH) in Florida

Research has shown that HIV-related stigma contributes to people living with HIV having a higher risk of mental health disorders. Our study examines the association between enacted HIV-related stigma and symptoms of anxiety and depression among PLWH. We used baseline data from 932 PLWH collected from the Florida Cohort study between 2014 and 2018. The sample was majority 45 + years of age (63.5%), male (66.0%), and Black (58.1%). The majority had previously experienced enacted HIV-related stigma (53.1%). Additionally, 56.6% and 65.2% showed mild to moderate/severe levels of anxiety and depression, respectively. Those who experienced any levels of enacted HIV-related stigma (vs none) had significantly greater odds of mild and moderate/severe levels of anxiety (vs no/minimal) (AOR[CI] 1.54[1.13, 2.10], p = 0.006; AOR[CI] 3.36[2.14, 5.26], p < 0.001, respectively) and depression (AOR[CI] 1.61[1.19, 2.18], p = 0.002; AOR[CI]  3.66[2.32, 5.77], p < 0.001, respectively). Findings suggest a need to evaluate interventions for PLWH to reduce the deleterious effects of enacted HIV-related stigma on mental health.

A mobile health intervention in HIV primary care: supporting patients at risk for ART non-adherence

Mobile health (mHealth) interventions that are integrated in HIV clinical settings to facilitate ongoing patient-provider communication between primary care visits are garnering evidence for their potential in improving HIV outcomes. Rango is an mHealth intervention to support engagement in HIV care and treatment adherence. This study used a single-arm prospective design with baseline and 6-month assessments for pre-post comparisons, as well as a matched patient sample for between-group comparisons to test Rango's preliminary efficacy in increasing viral suppression. The Rango sample (n = 406) was predominantly 50 years of age or older (63%; M = 50.67; SD = 10.97, 23-82), Black/African-American (44%) or Hispanic/Latinx (38%), and male (59%). At baseline, 18% reported missing at least one dose of ART in the prior three days and chart reviews of recent VL showed that nearly 82% of participants were virally suppressed. Overall 95% of the patients enrolled in Rango returned for a medical follow-up visit. Of the 65 unsuppressed patients at baseline who returned for a medical visit, 38 (59%) achieved viral suppression and only 5% of the suppressed group at baseline had an increase in viral load at 6 months despite being at risk for ART non-adherence. While viral suppression was similar between Rango participants and patients receiving treatment as usual over the same time period, it is unknown whether those patients were similarly at risk for non-adherence. Our findings support efforts to formally test this innovative approach in addressing ART non-adherence and viral suppression particularly to reach HIV treatment goals.

Impact of Pharmacist-Driven Antiretroviral Stewardship and Transitions of Care Interventions on Persons With Human Immunodeficiency Virus

Background

Persons with human immunodeficiency virus (HIV) experience high rates of medication-related errors when admitted to the inpatient setting. Data are lacking on the impact of a combined antiretroviral (ARV) stewardship and transitions of care (TOC) program. We investigated the impact of a pharmacist-driven ARV stewardship and TOC program in persons with HIV.

Methods

This was a retrospective, quasi-experimental analysis evaluating the impact of an HIV-trained clinical pharmacist on hospitalized persons with HIV. Patients included in the study were adults following up, or planning to follow up, at the University of Illinois (UI) outpatient clinics for HIV care and admitted to the University of Illinois Hospital. Data were collected between July 1, 2017 and December 31, 2017 for the preimplementation phase and between July 1, 2018 and December 31, 2018 for the postimplementation phase. Primary and secondary endpoints included medication error rates related to antiretroviral therapy (ART) and opportunistic infection (OI) medications, all-cause readmission rates, medication access at time of hospital discharge, and linkage to care rates.

Results

A total of 128 patients were included in the study: 60 in the preimplementation phase and 68 in the postimplementation phase. After the implementation of this program, medication error rates associated with ART and OI medications decreased from 17% (10 of 60) to 6% (4 of 68) (P = .051), 30-day all-cause readmission rates decreased significantly from 27% (16 of 60) to 12% (8 of 68) (P = .03), and linkage to care rates increased significantly from 78% (46 of 59) to 92% (61 of 66) (P = .02).

Conclusions

A pharmacist-led ARV stewardship and TOC program improved overall care of persons with HIV through reduction in medication error rates, all-cause readmission rates, and an improvement in linkage to care rates.

Qualitative Evaluation of Social Media and Mobile Technology Interventions Designed to Improve HIV Health Outcomes for Youth and Young Adults Living With HIV: A HRSA SPNS Initiative

Youth and young adults living with HIV (YYALH) are less likely to be engaged in HIV care, adhere to their medications, and achieve viral suppression compared to older adult populations. In the United States, the majority of YYALH belong to racial/ethnic, sexual, and gender minority groups. HIV care interventions are needed that specifically target YYALH and that exploit the use of social media and mobile technology (SMMT) platforms, where youth and young adults have a ubiquitous presence. We conducted a qualitative evaluation of SMMT interventions included in a Health Resources and Services Administration Special Projects of National Significance initiative designed to improve medical care engagement, retention, and medication adherence to achieve viral suppression among YYALH. However, in this study, only young adults living with HIV (YALH) ages 18 to 34 years participated. A total of 48 YALH were interviewed. The data were analyzed using thematic analysis and revealed three main themes supporting the usefulness of the SMMT interventions, which included (1) acceptability of SMMT interventions in managing HIV care with subthemes of medical information accessibility, reminders, and self-efficacy; (2) feelings of support and personal connection afforded by SMMT interventions; and (3) SMMT interventions help to alleviate negative feelings about status and mitigate HIV-related stigma. A few participants identified problems with using their respective intervention, primarily related to the functionality of the technologies. Overall, findings from our qualitative evaluation suggest that SMMT-based interventions have the potential to increase engagement and retention in care, support YALH in adhering to medication, and help them adjust to their diagnosis.

Sociodemographic, Ecological, and Spatiotemporal Factors Associated with Human Immunodeficiency Virus Drug Resistance in Florida: A Retrospective Analysis

BACKGROUND

Persons living with human immunodeficiency virus (HIV) with resistance to antiretroviral therapy are vulnerable to adverse HIV-related health outcomes and can contribute to transmission of HIV drug resistance (HIVDR) when nonvirally suppressed. The degree to which HIVDR contributes to disease burden in Florida-the US state with the highest HIV incidence- is unknown.

METHODS

We explored sociodemographic, ecological, and spatiotemporal associations of HIVDR. HIV-1 sequences (n = 34 447) collected during 2012-2017 were obtained from the Florida Department of Health. HIVDR was categorized by resistance class, including resistance to nucleoside reverse-transcriptase , nonnucleoside reverse-transcriptase , protease , and integrase inhibitors. Multidrug resistance and transmitted drug resistance were also evaluated. Multivariable fixed-effects logistic regression models were fitted to associate individual- and county-level sociodemographic and ecological health indicators with HIVDR.

RESULTS

The HIVDR prevalence was 19.2% (nucleoside reverse-transcriptase inhibitor resistance), 29.7% (nonnucleoside reverse-transcriptase inhibitor resistance), 6.6% (protease inhibitor resistance), 23.5% (transmitted drug resistance), 13.2% (multidrug resistance), and 8.2% (integrase strand transfer inhibitor resistance), with significant variation by Florida county. Individuals who were older, black, or acquired HIV through mother-to-child transmission had significantly higher odds of HIVDR. HIVDR was linked to counties with lower socioeconomic status, higher rates of unemployment, and poor mental health.

CONCLUSIONS

Our findings indicate that HIVDR prevalence is higher in Florida than aggregate North American estimates with significant geographic and socioecological heterogeneity.

Health Care-Specific Enacted HIV-Related Stigma's Association with Antiretroviral Therapy Adherence and Viral Suppression Among People Living with HIV in Florida

Among people living with HIV (PLWH) in Florida, <2/3 are virally suppressed (viral load <200 copies/mL). Previous theoretical frameworks have pointed to HIV-related stigma as an important factor for viral suppression; an important outcome related to the HIV continuum of care. This study aims to analyze the association between enacted HIV-related stigma and antiretroviral therapy (ART) adherence and viral suppression among a sample of PLWH in Florida. The overall sample (n = 932) was male (66.0%), majority greater than 45 years of age (63.5%), black (58.1%), and non-Hispanic (79.7%). Adjusted odds ratios (AOR) and 95% confidence intervals (CI) were estimated using logistic regression models. The odds of nonadherence to ART was not significantly greater for those reporting low/moderate or high levels of general enacted HIV-related stigma (vs. no stigma) [AOR = 1.30, CI: (0.87-1.95), p = 0.198; AOR = 1.17, CI: (0.65-2.11), p = 0.600, respectively]. Moreover, the odds of nonviral suppression were not significantly greater for those reporting low/moderate or high levels of general enacted HIV-related stigma (vs. no stigma) [AOR = 0.92, CI: (0.60-1.42), p = 0.702; AOR = 1.16, CI: (0.64-2.13), p = 0.622, respectively]. However, ever experiencing health care-specific enacted HIV-related stigma was associated with both nonadherence [AOR = 2.29, CI: (1.25-4.20), p = 0.008] and nonsuppression [AOR = 2.16, CI: (1.19-3.92), p = 0.011]. Despite limitations, the results suggest that the perpetuation of stigma by health care workers may have a larger impact on continuum of care outcomes of PLWH than other sources of enacted stigma. Based on the results, there is a need to develop and evaluate interventions for health care workers intended to reduce experienced stigma among PLWH and improve health outcomes.

A Systematic Mixed Studies Review of the Intersections of Social-Ecological Factors and HIV Stigma in People Living With HIV in the U.S. South

The role of stigma on psychological wellness and treatment outcomes in people living with HIV (PLWH) has been well documented. However, within the context of the southern United States, the intersection between HIV-related stigma and social-ecological factors has been understudied. Thus, a results-based convergent, mixed synthesis design was used to examine the manifestations of HIV-related stigma in PLWH in the U.S. South. A literature search was conducted using PsycINFO, PubMed (includes MEDLINE), and CINAHL. The first level of screening by title and abstract was administered on 1,829 articles. A full-text screening of 169 studies was completed, and a total of 30 relevant articles were extracted. The mixed synthesis highlighted intervention strategies that can reduce HIV-related stigma while promoting positive health-behavior change. The findings of this review underscored the uniqueness of PLWH in the south and demonstrated the crucial role of intersectionality in investigating HIV-related stigma in treating and preventing HIV.

Identifying patterns of retention in care and viral suppression using latent class analysis among women living with HIV in Florida 2015-2017

The study objective was to classify women with newly diagnosed HIV into patterns of retention in care (≥2 HIV care visits ≥3 months apart) and viral suppression over time and identify factors associated with class membership. Florida HIV/AIDS surveillance data were used to conduct Latent Class Analysis to classify women into patterns, and multinomial regression was used to compare the prevalence of class membership by demographic and clinical factors. Four classes were selected based on model fit parameters: (Class 1) consistently retained and suppressed (>90% probability of being retained and suppressed), (Class 2) not consistently retained or suppressed (≤10% probability of being retained and suppressed), (Class 3) increasingly retained and suppressed, and (Class 4) decreasingly retained and suppressed. The proportion of women in each class was 48.6%, 24.9%, 14.3%, and 12.2%, respectively. Women aged 25-34 compared to 35-49 years old, injection drug use mode of exposure, US born, and not linked to care three months post-diagnosis had a lower prevalence of belonging to the consistently retained and suppressed class. Findings may be useful in tailoring and targeting interventions to increase the prevalence of women who are consistently retained in care and virally suppressed.

The Role of Neighborhood Poverty in the Association between Foreign-Born status and HIV Care Continuum Outcomes in Alameda County, California

Foreign-born persons living in the US have an increased risk of exposure to HIV and higher rates of HIV diagnosis (Patel-Larson et al. in Poster presented at the 2007 National HIV Prevention Conference, pp 2-5, 2007; Prosser et al. in JAMA 308:601-607, 2012). Foreign-born persons also tend to live in areas with high concentration of immigrants and more often neighborhoods of high poverty, for at least some time (Jargowsky in J Ethn Migr Stud 35:1129-1151, 2009). Using HIV surveillance data in Alameda County, California, we examined whether the association between immigrant status and the four outcomes on the HIV care cascade (late diagnosis, linkage to care within 30 days of diagnosis, retention in HIV care, and viral load status a year after diagnosis) differed by census tract poverty level. We used generalized estimating equations (GEE) adjusted for sex at birth, age, race, and transmission mode. Of 1235 individuals with HIV diagnosis reported between 2011 and 2016, 29% were foreign-born. Foreign-born status was significantly associated with late HIV diagnosis but not with linkage, retention in care, and achievement of undetectable viral load a year after diagnosis. Neighborhood poverty modified the association between immigrant status and retention in care, but not late diagnosis, linkage or viral load status. Our findings suggest that neighborhood resources may buffer against disparities in retention. Thus, immigrants in poorer neighborhoods may require more support to stay in care.

Development and Validation of a Risk Prediction Tool to Identify People with HIV Infection Likely Not to Achieve Viral Suppression

Identifying people with HIV infection (PHIV), who are at risk of not achieving viral suppression, is important for designing targeted intervention. The aim of this study was to develop and test a risk prediction tool for PHIV who are at risk of not achieving viral suppression after a year of being in care. We used retrospective data to develop an integer-based scoring method using backward stepwise logistic regression. We also developed risk score categories based on the quartiles of the total risk score. The risk prediction tool was internally validated by bootstrapping. We found that nonviral suppression after a year of being in care among PHIV can be predicted using seven variables, namely, age group, race, federal poverty level, current AIDS status, current homelessness status, problematic alcohol/drug use, and current viral suppression status. Those in the high-risk category had about a 23 increase in the odds of nonviral suppression compared with the low-risk group. The risk prediction tool has good discriminative performance and calibration. Our findings suggest that nonviral suppression after a year of being in care can be predicted using easily available variables. In settings with similar demographics, the risk prediction tool can assist health care providers in identifying high-risk individuals to target for intervention. Follow-up studies are required to externally validate this risk prediction tool.

Disparities in Retention in Care Among Adults Living with HIV/AIDS: A Systematic Review

As national HIV prevention goals aim to increase the proportion of persons living with HIV, determining existing disparities in retention in care will allow for targeted intervention. The purpose of this systematic review was to identify existing disparities in retention in care. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA-P) 2015 guided this systematic review. Electronic databases, including PubMed/MEDLINE, CINAHL, Sociological Collection, PsychInfo, and Cab Direct/Global Health, were systematically searched and twenty studies were included. This review identified disparities in retention in care that have been documented by race, gender, age, HIV exposure, incarceration history, place of birth, and U.S. geographic location. Research is necessary to further identify existing disparities in retention in care and to better understand determinants of health disparities. Additionally, interventions must be tailored to meet the needs of health disparate populations and should be assessed to determine their effectiveness in reducing health disparities.

Sustained HIV viral suppression among men who have sex with men in the Miami-Dade County Ryan White Program: the effect of demographic, psychosocial, provider and neighborhood factors

Background

HIV viral suppression is associated with health benefits for people living with HIV and a decreased risk of HIV transmission to others. The objective was to identify demographic, psychosocial, provider and neighborhood factors associated with sustained viral suppression among gay, bisexual, and other men who have sex with men.

Methods

Data from adult men who have sex with men (MSM) enrolled in the Miami-Dade County Ryan White Program (RWP) before 2017 were used. Sustained viral suppression was defined as having an HIV viral load < 200 copies/ml in all viral load tests in 2017. Three-level (individual, medical case management site, and neighborhood) cross-classified mixed-effect models were used to estimate adjusted odds ratios (aOR) and 95% confidence intervals (CI) for sustained viral suppression.

Results

Of 3386 MSM, 90.8% were racial/ethnic minorities, and 84.4% achieved sustained viral suppression. The odds of achieving sustained viral suppression was lower for 18–24 and 25–34 year-old MSM compared with 35–49 year-old MSM, and for non-Latino Black MSM compared with White MSM. Those not enrolled in the Affordable Care Act, and those with current AIDS symptoms and a history of AIDS had lower odds of achieving sustained viral suppression. Psychosocial factors significantly associated with lower odds of sustained viral suppression included drug/alcohol use, mental health symptoms, homelessness, and transportation to appointment needs. Individuals with an HIV physician who serves a larger volume of RWP clients had greater odds of sustained viral suppression. Neighborhood factors were not associated with sustained viral suppression.

Conclusion

Despite access to treatment, age and racial disparities in sustained viral suppression exist among MSM living with HIV. Addressing substance use, mental health, and social services’ needs may improve the ability of MSM to sustain viral suppression long-term. Furthermore, physician characteristics may be associated with HIV outcomes and should be explored further.

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.

Barriers and Facilitators for Antiretroviral Treatment Adherence Among HIV-Positive African American and Latino Men Who Have Sex With Men

Some Black/African American and Hispanic/Latino men who have sex with men (MSM) living with HIV do not take antiretroviral therapy (ART). We conducted semistructured interviews with 84 adult, Black/African American and Hispanic/Latino MSM with HIV to understand ART barriers and facilitators. We used chi-square statistics to identify factors associated with ART use (p ≤ .05), and selected illustrative quotes. Over half (51.2%) said they followed their doctor's instructions; however, only 27.4% reported consistently taking ART. Some men delayed ART until overcoming diagnosis denial or becoming very sick. ART use was facilitated by encouragement from others, treatment plans, side effect management, lab test improvements, pill-taking reminders, and convenient care facilities that provide "one-stop shop" services. Men were more likely to take ART when having providers who communicated effectively and were perceived to treat them with respect. Healthcare personnel can use our findings to strengthen services for MSM of color.

HIV outcomes among migrants from low-income and middle-income countries living in high-income countries: a review of recent evidence

PURPOSE OF REVIEW

Migrants living in high-income countries are disproportionately affected by HIV infection and frequently have characteristics associated with poor HIV clinical outcomes. HIV epidemiology among migrants is influenced by changes in migration patterns and variations in transmission risk behaviors. Here we review the recently published literature on known HIV outcomes among migrants from low-income and middle-income countries living in high-income countries.

RECENT FINDINGS

High proportions of migrants acquire HIV after migration, and this group frequently presents to care late. Once established in care, migrants are often more likely to experience worse HIV treatment outcomes compared with native populations. Multiple individual and structural factors influence HIV diagnosis and treatment outcomes among migrants, including disruption of social networks, increased sexual risk behaviors, communication barriers, limited access to care, and stigma. Few studies have examined interventions targeted at improving HIV outcomes among migrants.

SUMMARY

Stigma and limited access to care appear to be primary drivers of poor HIV outcomes among migrants in high-income countries. Addressing these disparities is limited by difficulties in identifying and monitoring this population as well as a lack of evidence regarding appropriate interventions for migrants living with HIV. Improving outcomes for this group requires interventions that are specifically targeted at this marginalized and growing population.

The association between symptoms of generalized anxiety disorder and appointment adherence, overnight hospitalization, and emergency department/urgent care visits among adults living with HIV enrolled in care

This study examined the association between generalized anxiety disorder (GAD) symptoms and healthcare utilization (HCU) among 801 people living with HIV (PLWH). Participants recruited from community health centers in Florida completed questionnaires assessing demographics, substance use, symptoms of GAD and depression, and HCU. Adjusted binary and multinomial logistic regressions assessed the association between moderate-severe GAD symptoms and past 6-month missed HIV-care appointments, overnight hospitalization, and emergency department (ED)/urgent care visits. Participants reporting moderate-severe GAD symptoms had a greater odds of missing an HIV-care appointment (AOR 2.03, 95% CI 1.28-3.24, p = 0.003), spending 2 (AOR 4.35, 95% CI 2.18-8.69, p < 0.001) or 3+ (AOR 2.79, 95% CI 1.20-6.45, p = 0.016) nights in the hospital, and visiting an ED/urgent care facility 2 (AOR 2.63, 95% CI 1.39-4.96, p = 0.003) or 3+ (AOR 2.59, 95% CI 1.27-5.26 p = 0.008) times compared to participants reporting none-mild anxiety. Depression was associated with fewer ED/urgent care visits and overnight hospitalizations, while no association was found with missed primary care appointments. The role of anxiety in illness management remains understudied among PLWH. Anxiety identification and the development of interventions for anxiety among PLWH may have important consequences for healthcare cost saving, patient retention in care, and HIV-disease management.

Do Symptoms of Depression Interact with Substance Use to Affect HIV Continuum of Care Outcomes?

Few studies examine how depression and substance use interact to affect HIV control. In 14,380 persons with HIV (PWH), we used logistic regression and generalized estimating equations to evaluate how symptoms of depression interact with alcohol, cocaine, opioid, and methamphetamine use to affect subsequent retention in care, maintaining an active prescription for ART, and consistent virologic suppression. Among PWH with no or mild depressive symptoms, heavy alcohol use had no association with virologic suppression (OR 1.00 [0.95-1.06]); among those with moderate or severe symptoms, it was associated with reduced viral suppression (OR 0.80 [0.74-0.87]). We found no interactions with heavy alcohol use on retention in care or maintaining ART prescription or with other substances for any outcome. These results highlight the importance of treating moderate or severe depression in PWH, especially with comorbid heavy alcohol use, and support multifaceted interventions targeting alcohol use and depression.

Multi-Site Evaluation of Community-Based Efforts to Improve Engagement in HIV Care Among Populations Disproportionately Affected by HIV in the United States

This study assesses effects of a community-based intervention across seven sites in the United States on HIV care utilization and study retention, among people living with HIV (PLWH). A two-armed study was conducted from 2013 to 2016 in each of seven community-based agencies across the United States. Each site conducted interventions involving community engagement approaches in the form of case management or patient navigation. Control conditions were standard of care involving referral to HIV clinical care. Participants (N = 583) were adults reporting erratic or no HIV care in the past 6 months. Longitudinal survey data on demographics, behavioral risks, and HIV care were collected from participants at baseline, before service delivery, and at 6-month follow-up. Unadjusted and adjusted generalized linear mixed models were used to assess the intervention effects on HIV care utilization and study retention. Participants were majority black (75.5%), cisgender male (55.1%), and heterosexual (55.4%). No significant intervention effect was observed on HIV care utilization, although both groups improved significantly over time [adjusted odds ratio (AOR): 2.09, 95% confidence interval (CI): 1.30-3.37]. Intervention participants were more likely to be retained in the study (AOR: 1.50, 95% CI: 1.03-2.20). Community intervention did not affect HIV care utilization more than standard of care, but intervention participants were more likely to be retained in the study, suggesting that such approaches support relationship building in ways that can facilitate follow-up of socially vulnerable PLWH. More research is needed to understand how such community efforts can support better HIV care utilization in these populations.

Gender Differences in HIV Testing, Diagnosis, and Linkage to Care in Healthcare Settings: Identifying African American Women with HIV in Chicago

Women account for 25% of all people living with HIV and 19% of new diagnoses in the United States. African American (AA) women are disproportionately affected. Yet, differences in the care continuum entry are not well understood between patient populations and healthcare sites. We aim to examine gender differences in diagnosis and linkage to care (LTC) in the Expanded HIV Testing and Linkage to Care (X-TLC) program within healthcare settings. Data were collected from 14 sites on the South and West sides of Chicago. Multivariate logistic regression analysis was used to determine the differences in HIV diagnoses and LTC by gender and HIV status. From 2011 to 2016, X-TLC performed 281,017 HIV tests; 63.7% of those tested were women. Overall HIV seroprevalence was 0.57%, and nearly one third (29.4%) of HIV-positive patients identified were cisgender women. Of newly diagnosed HIV-positive women, 89% were AA. 58.5% of new diagnoses in women were made at acute care hospitals, with the remainder at community health centers. Women who were newly diagnosed had a higher baseline CD4 count at diagnosis compared with men. Overall, women had lower odds of LTC compared with men (adjusted odds ratio = 0.58, 95% confidence interval 0.44-0.78) when controlling for patient demographics and newly versus previously diagnosed HIV status. Thus, interventions that focus on optimizing entry into the care continuum for AA women need to be explored.

Identifying Spatial Variation Along the HIV Care Continuum: The Role of Distance to Care on Retention and Viral Suppression

Distance to HIV care may be associated with retention in care (RIC) and viral suppression (VS). RIC (≥ 2 HIV visits or labs ≥ 90 days apart in 12 months), prescribed antiretroviral therapy (ART), VS (< 200 copies/mL at last visit) and distance to care were estimated among 3623 DC Cohort participants receiving HIV care in 13 outpatient clinics in Washington, DC in 2015. Logistic regression models and geospatial statistics were computed. RIC was 73%; 97% were on ART, among whom 77% had VS. ZIP code-level clusters of low RIC and high VS were found in Northwest DC, and low VS in Southeast DC. Those traveling ≥ 5 miles had 30% lower RIC (adjusted odds ratio (aOR) 0.71, 95% CI 0.58, 0.86) and lower VS (OR 0.70, 95% CI 0.52, 0.94). Geospatial clustering of RIC and VS was observed, and distance may be a barrier to optimal HIV care outcomes.
