Abstract
As social and economic conditions are key determinants of HIV, the United States 'National HIV/AIDS Strategy (NHAS)', in addition to care and treatment, aims to address mental health, unemployment, food insecurity, and housing instability, as part of its strategic plan for the 'Ending the HIV Epidemic' initiative. Although mechanistic models of HIV play a key role in evaluating intervention strategies, social conditions are typically not part of the modeling framework. Challenges include the unavailability of coherent statistical data for social conditions and behaviors. We developed a method, combining undirected graphical modeling with copula methods, to integrate disparate data sources, to estimate joint probability distributions for social conditions and behaviors. We incorporated these in a national-level network model, Progression and Transmission of HIV (PATH 4.0), to simulate behaviors as functions of social conditions and HIV transmissions as a function of behaviors. As a demonstration for the potential applications of such a model, we conducted two hypothetical what-if intervention analyses to estimate the impact of an ideal 100% efficacious intervention strategy. The first analysis modeled care behavior (using viral suppression as proxy) as a function of depression, neighborhood, housing, poverty, education, insurance, and employment status. The second modeled sexual behaviors (number of partners and condom-use) as functions of employment, housing, poverty, and education status, among persons who exchange sex. HIV transmissions and disease progression were then simulated as functions of behaviors to estimate incidence reductions. Social determinants are key drivers of many infectious and non-infectious diseases. Our work enables the development of decision support tools to holistically evaluate the syndemics of health and social inequity.

Abstract
Disparities in HIV care by socioeconomic status, place of residence, and race/ethnicity prevent progress toward epidemic control. No study has comprehensively characterized the HIV care cascade among people with HIV enrolled in Medicaid - an insurance source for low-income individuals in the US. We analyzed data from 246,127 people with HIV enrolled in Medicaid 2001-2015, aged 18-64, living in 14 US states. We estimated the monthly prevalence of four steps of the care cascade: retained in care/adherent to ART; retained/not adherent; not retained/adherent; not retained/not adherent. Beneficiaries were retained in care if they had an outpatient care encounter every six months. Adherence was based on medication possession ratio. We estimated prevalence using a non-parametric multi-state approach, accounting for death as a competing event and for Medicaid disenrollment using inverse probability of censoring weights. Across 2001-2015, the proportion of beneficiaries with HIV who were retained/ART adherent increased, overall and in all subgroups. By 2015, approximately half of beneficiaries were retained in care, and 42% of beneficiaries were ART adherent. We saw meaningful differences by race/ethnicity and region. Our work highlights an important disparity in the HIV care cascade by insurance status during this time period.

Abstract
OBJECTIVE Assessing mobility among people with HIV is an important consideration when measuring HIV incidence, prevalence, and the care continuum in the United States. Our aims were to measure mobility among people with HIV compared with the general population and to examine factors associated with migration among people with HIV. METHODS We calculated state-to-state move-in and move-out migration rates for 2011 through 2019 using National HIV Surveillance System data for people with HIV and using US Census data for the general population. For people with HIV, we also assessed the association between migration and HIV care outcomes. RESULTS From 2011 through 2019, the US general population had stable migration, whereas migration rates among people with HIV fluctuated and were higher than among the general population. Among people with HIV, migration rates in 2019 were higher among people assigned male sex at birth versus female sex at birth, among people aged ≤24 years versus ≥25 years, among people with HIV infection attributed to male-to-male sexual contact versus other transmission categories, and among non-Hispanic Other people (ie, American Indian or Alaska Native, Asian, Native Hawaiian or Other Pacific Islander, or multiple races) versus Hispanic, non-Hispanic Black, and non-Hispanic White people. Receipt of HIV medical care (90.3% vs 75.5%) and achieving viral suppression (72.1% vs 65.3%) were higher among people with HIV who migrated versus those who did not. CONCLUSIONS People with HIV in the United States are more mobile than the general population. Determining the mobility of people with HIV can help with strategic allocation of HIV prevention and care resources.

Abstract
Adverse childhood experiences (ACEs) have been linked to numerous negative health outcomes in adulthood and have been recognized as a hurdle to participating in HIV care. However, few studies have examined the cumulative impact that different types of childhood trauma have on HIV care engagement and HIV outcomes. This study characterized the relationship between ACEs, viral suppression, and health-related quality of life (HRQOL) among persons living with HIV (PLWH). We used HIV surveillance data and self-reported information on ACEs and HRQOL from PLWH in Washington State from 2018-2020. Logistic regression was used to assess the relationship between the quantity and type of ACEs and viral suppression. We used Poisson regression to examine the relationship between ACEs and HRQOL as measured by unhealthy days. The majority of PLWH experienced ≥1 ACE (86.8%). ACEs were not significantly associated with the likelihood of viral suppression (OR ≥4 vs 0 ACEs: 0.49, 95% CI: 0.12-2.09), but ACEs were associated with more unhealthy days experienced in a 30-day period (RR ≥4 vs 0 ACEs: 3.19, 95% CI: 1.59-6.40). These findings provide support that trauma is common among PLWH, and efforts to address the impact of childhood trauma may work to improve quality of life.

Abstract
Housing plays a critical role in the care outcomes of individuals living with a HIV, yet few studies have examined the unique housing profiles of women living with HIV (WLH), especially among those belonging to low-income racial/ethnic minority groups. In this study, authors conducted a latent class analysis to generate latent profiles of women (N = 1,501) according to their housing status and household characteristics and assessed associations between classes and sociodemographic and behavioral characteristics and between classes and three HIV care outcomes: retention in care, viral suppression, and sustained viral suppression. A three-class model was selected using five dichotomized housing indicators: housing status, head of household status, living with minors, living with another adult, and disclosure of HIV status to adults with whom they live. While class 1 and class 2 had comparable HIV care outcomes, women in class 3-who were predominately unstably housed, living alone, and did not disclose their HIV status with those with whom they lived-had significantly lower crude odds of successful care outcomes. When accounting for sociodemographic and behavioral factors, significant differences in retention in care persisted. Findings underscore the need for tailored interventions for subgroups of low-income WLH and provide contextual details around the role of housing experiences.

Abstract
OBJECTIVES To reduce the number of new HIV infections and improve HIV health care outcomes, the social conditions in which people live and work should be assessed. The objective of this study was to describe linkage to HIV medical care by selected demographic characteristics and social determinants of health (SDH) among US adults with HIV at the county level. METHODS We used National HIV Surveillance System data from 42 US jurisdictions and data from the American Community Survey to describe differences in linkage to HIV medical care among adults aged ≥18 with HIV infection diagnosed in 2017. We categorized SDH variables into higher or lower levels of poverty (where <13% or ≥13% of the population lived below the federal poverty level), education (where <13% or ≥13% of the population had RESULTS Of 33 204 adults with HIV infection diagnosed in 2017, 78.4% were linked to HIV medical care ≤1 month after diagnosis. Overall, rates of linkage to care were significantly lower among men and women living in counties with higher versus lower poverty (PR = 0.96; 95% CI, 0.94-0.97), with lower versus higher health insurance coverage (PR = 0.93; 95% CI, 0.92-0.94), and with lower versus higher education levels (PR = 0.97; 95% CI, 0.96-0.98). CONCLUSIONS Increasing health insurance coverage and addressing economic and educational disparities would likely lead to better HIV care outcomes in these areas.

Abstract
BACKGROUND A wealth of scientific evidence supports the effectiveness of HIV prophylaxis and treatment. Homelessness is strongly associated with the health status and viral suppression among underserved populations and can undermine the national plan to eliminate HIV by 2030. This retrospective observational study examined the extent in which homelessness affects HIV treatment in an underserved urban area of Middle Tennessee in 2014-2019. RESULTS Among 692 HIV-seropositive patients, the proportion of homeless patients increased from 13.5% in 2014 to 27.7% in 2019, thrice the national average for HIV-seropositive people (8.4%) and twice that of HIV positive patients who are participating in Ryan White programs nationwide (12.9%). Our findings suggest that homeless patients were half as likely to achieve viral suppression as compared to those who had a permanent/stable home [OR 0.48 (0.32-0.72), p-value < 0.001]. CONCLUSION Our study indicates that homelessness may play an important role in viral suppression among persons living with HIV/AIDS in Middle Tennessee.

Abstract
Scale-up of pre-exposure prophylaxis (PrEP) in people who inject drugs (PWID) remains suboptimal. Patient-level factors are often complex and may contribute to scale-up. Using cross-sectional data from 234 opioid-dependent patients on methadone who met eligibility criteria for PrEP, we conducted logistic regression analyses to assess potential moderators associated with being on PrEP (n = 60). Mean provider trust was significantly higher among Blacks vs Whites (39.4 vs 34.9; p = 0.002) and non-homeless vs homeless participants (37.5 vs 34.8; p = 0.008). Though race/ethnicity was not a significant moderator on provider trust and PrEP use, increased provider trust was marginally associated with increased PrEP use among Blacks (p = 0.058). Additionally, homelessness significantly moderated provider trust and PrEP use (p = 0.024). Provider trust among non-homeless participants was positively correlated with PrEP use (p = 0.013) but not among homeless participants. Strategies that promote provider trust in Blacks and non-homeless PWID on methadone may improve PrEP scale-up.

Abstract
BACKGROUND Numerous factors impact HIV care, often requiring consideration of indices to prevent collinearity when using statistical modeling. Using the Behavioral Model for Vulnerable Populations, we developed vulnerable and enabling indices for people living with HIV (PLWH). METHODS We used Ryan White Program (RWP) data and principal component analysis to develop general and gender- and racial/ethnic-specific indices. We assessed internal reliability (Cronbach's alpha), convergent validity (correlation coefficient), and predictive utility (logistic regression) with non-viral suppression. RESULTS Three general factors accounting for 79.2% of indicators' variability surfaced: mental health, drug use, and socioeconomic status (Cronbach's alpha 0.68). Among the overall RWP population, indices showed convergent validity and predictive utility. Using gender- or racial/ethnic-specific indices did not improve psychometric performance. DISCUSSION General mental health, drug use, and socioeconomic indices using administrative data showed acceptable reliability, validity, and utility for non-viral suppression in an overall PLWH population and in gender- and racial/ethnic-stratified populations. These general indices may be used with similar validity and utility across gender and racial/ethnic diverse populations.

Abstract
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.

Abstract
BACKGROUND A better understanding of the baseline characteristics of elderly people living with HIV/AIDS (PLWHA) is relevant because the world's HIV population is ageing. OBJECTIVES This study aimed to evaluate the baseline characteristics of PLWHA aged ≥ 50years at recruitment to HIV/AIDS clinic compared against the viral load (VL) and CD4 count among patients attending Kisii Teaching and Referral Hospital (KTRH), Kenya. METHODS We retrospectively evaluated temporal inclinations of CD4 levels, viral load change and baseline demographic characteristics in the electronic records at the hospital using a mixed error-component model for 1329 PLWHA attending clinic between January 2008 and December 2019. RESULTS Findings showed a significant difference in the comparison between baseline VL and WHO AIDS staging (p=0.026). Overall VL levels decreased over the period significantly by WHO AIDS staging (p<0.0001). Significant difference was observed by gender (p<0.0001), across age groups (p<0.0001) and baseline CD4 counts (p=0.003). There were significant differences in WHO staging by CD4 count >200cell/mm3 (p=0.048) and residence (p=0.001). CONCLUSION Age, WHO AIDS staging, gender and residence are relevant parameters associated with viral load decline and CD4 count in elderly PLWHA. A noticeable VL suppression was attained confirming possible attainment of VL suppression among PLWHA under clinical care.

Abstract
Among 958 applicants to a supportive housing program for low-income persons living with HIV (PLWH) and mental illness or a substance use disorder, we assessed impacts of housing placement on housing stability, HIV care engagement, and viral suppression. Surveillance and administrative datasets provided medical and residence information, including stable (e.g., rental assistance, supportive housing) and unstable (e.g., emergency shelter) government-subsidized housing. Sequence analysis identified a "quick stable housing" pattern for 67% of persons placed by this program within 2 years, vs. 28% of unplaced. Compared with unplaced persons not achieving stable housing quickly, persons quickly achieving stable housing were more likely to engage in care, whether placed (per Poisson regression, ARR: 1.14;95% CI 1.09-1.20) or unplaced (1.19;1.13-1.25) by this program, and to be virally suppressed, whether placed (1.22;1.03-1.44) or unplaced (1.26, 1.03-1.56) by this program. Housing programs can help homeless PLWH secure stable housing quickly, manage their infection, and prevent transmission.

Protocol of a randomized controlled trial to test the effects of client-centered Representative Payee Services on antiretroviral therapy adherence among marginalized people living with HIV. BMC Public Health 2020; 20:1443. [PMID: 32967646 PMCID: PMC7509495 DOI: 10.1186/s12889-020-09500-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2020] [Accepted: 09/03/2020] [Indexed: 11/12/2022] Open
Abstract
BACKGROUND Client-Centered Representative Payee (CCRP) is an intervention modifying implementation of a current policy of the US Social Security Administration, which appoints organizations to serve as financial payees on behalf of vulnerable individuals receiving Social Security benefits. By ensuring beneficiaries' bills are paid while supporting their self-determination, this structural intervention may mitigate the effects of economic disadvantage to improve housing and financial stability, enabling self-efficacy for health outcomes and improved antiretroviral therapy adherence. This randomized controlled trial will test the impact of CCRP on marginalized people living with HIV (PLWH). We hypothesize that helping participants to pay their rent and other bills on time will improve housing stability and decrease financial stress. METHODS PLWH (n = 160) receiving services at community-based organizations will be randomly assigned to the CCRP intervention or the standard of care for 12 months. Fifty additional participants will be enrolled into a non-randomized ("choice") study allowing participant selection of the CCRP intervention or control. The primary outcome is HIV medication adherence, assessed via the CASE adherence index, viral load, and CD4 counts. Self-assessment data for ART adherence, housing instability, self-efficacy for health behaviors, financial stress, and retention in care will be collected at baseline, 3, 6, and 12 months. Viral load, CD4, and appointment adherence data will be collected at baseline, 6, 12, 18, and 24 months from medical records. Outcomes will be compared by treatment group in the randomized trial, in the non-randomized cohort, and in the combined cohort. Qualitative data will be collected from study participants, eligible non-participants, and providers to explore underlying mechanisms of adherence, subjective responses to the intervention, and implementation barriers and facilitators. DISCUSSION The aim of this study is to determine if CCRP improves health outcomes for vulnerable PLWH. Study outcomes may provide information about supports needed to help economically fragile PLWH improve health outcomes and ultimately improve HIV health disparities. In addition, findings may help to refine service delivery including the provision of representative payee to this often-marginalized population. This protocol was prospectively registered on May 22, 2018 with ClinicalTrials.gov (NCT03561103) .

Abstract
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.

Abstract
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.

Abstract
PURPOSE The Seek and Treat for Optimal Prevention of HIV/AIDS (STOP HIV/AIDS) Program Evaluation (SHAPE) study is a longitudinal cohort developed to monitor the progress of an HIV testing and treatment expansion programme across the province of British Columbia (BC). The study considers how sociostructural determinants such as gender, age, sexual identity, geography, income and ethnicity influence engagement in HIV care. PARTICIPANTS Between January 2016 and September 2018, 644 BC residents who were at least 19 years old and diagnosed with HIV were enrolled in the study and completed a baseline survey. Participants will complete two additional follow-up surveys (18 months apart) about their HIV care experiences, with clinical follow-up ongoing. FINDINGS TO DATE Analyses on baseline data have found high levels of HIV care engagement and treatment success among SHAPE participants, with 95% of participants receiving antiretroviral therapy and 90% having achieved viral suppression. However, persistent disparities in HIV treatment outcomes related to age, injection drug use and housing stability have been identified and require further attention when delivering services to marginalised groups. FUTURE PLANS Our research will examine how engagement in HIV care evolves over time, continuing to identify barriers and facilitators for promoting equitable access to treatment and care among people living with HIV. A qualitative research project, currently in the formative phase, will compliment quantitative analyses by taking a strengths-based approach to exploring experiences of engagement and re-engagement in HIV treatment among individuals who have experienced delayed treatment initiation or treatment interruptions.

Abstract
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.

Abstract
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.

Abstract
BACKGROUND Although treatment for HIV infection is widely available and well tolerated, less than 30% of adolescents and young adults living with HIV infection achieve stable viral suppression. Mobile technology affords increased opportunities for young people living with HIV to engage with information, health management tools, and social connections that can support adherence to treatment recommendations and medication. Although mobile apps are increasingly prevalent, few are informed by the target population. OBJECTIVE The objective of this study was to describe the "Positive Peers" app, a mobile app currently being evaluated in a public hospital in the Midwestern United States. Formative development, key development strategies, user recruitment, and lessons learned are discussed in this paper. METHODS "Positive Peers" was developed in collaboration with a community advisory board (CAB) comprising in-care young adults living with HIV and a multidisciplinary project team. Mobile app functions and features were developed over iterative collaborative sessions that were tailored to the CAB members. In turn, the CAB built rapport with the project team and revealed unique information that was used in app development. RESULTS The study was funded on September 1, 2015; approved by the MetroHealth Institutional Review Board on August 31, 2016; and implemented from October 11, 2016, to May 31, 2019. The "Positive Peers" mobile app study has enrolled 128 users who reflect priority disparity population subgroups. The app administrator had frequent contact with users across app administration and study-related activities. Key lessons learned from the study include changing privacy concerns, data tracking reliability, and user barriers. Intermediate and outcome variable evaluation is expected in October 2019. CONCLUSIONS Successful development of the "Positive Peers" mobile app was supported by multidisciplinary expertise, an enthusiastic CAB, and a multifaceted, proactive administrator.

Abstract
Consistent antiretroviral adherence is key to viral suppression, but many low-income people of color living with HIV are not optimally adherent due to a wide variety of interrelated social and structural factors. Previous studies have found that HIV medication beliefs are an important facet of adherence. In contrast to the AZT era , currently available antiretroviral therapies are significantly safer and more effective, but research suggests that negative beliefs may persist among racial and ethnic minority people. Twenty-seven semi-structured interviews were conducted with low-income Black and Latinx people living with HIV in New York City that were currently, or had been recently, disengaged from outpatient HIV medical care. This research suggests that socially and economically marginalized people living with HIV, many long-term survivors who lived through the AZT era, recognized that current treatments are very effective in making HIV a chronic, manageable illness and a significant improvement compared to the therapies early in the epidemic. Most importantly, the data suggests that people demonstrate great resilience despite their experiences of social and economic exclusion. Both clinical practice and public health interventions can benefit from these findings. HIV care providers should speak with patients about their beliefs related to HIV medication, and public health interventions should specifically address HIV medication-related beliefs in order to enhance adherence. In order to avoid reifying people's marginalization, public health should endeavor to recognize and support people's resilience.

Abstract
The lack of stable housing can impair access and continuity of care for patients living with human immunodeficiency virus (HIV). This study investigated the relationship between housing status assessed at multiple time points and several core HIV-related outcomes within the same group of HIV patients experiencing homelessness. Patients with consistently stable housing (CSH) during the year were compared to patients who lacked CSH (non-CSH group). The study outcomes included HIV viral load (VL), CD4 counts, and health care utilization. Multivariable and propensity weighted analyses were used to assess outcomes adjusting for potential group differences. Of 208 patients, 88 (42%) had CSH and 120 (58%) were non-CSH. Patients with CSH had significantly higher proportion of VL suppression and higher mean CD4 counts. The frequency of nurse visits in the CSH group was less than a half of that in the non-CSH group. Patients with CSH were less likely to be admitted to the medical respite facility, and if admitted, their length of stay was about a half of that for the non-CSH group. Our study findings show that patients with CSH had significantly better HIV virologic control and immune status as well as improved health care utilization.

Factors Associated With Gaps in Medicaid Enrollment Among People With HIV and the Effect of Gaps on Viral Suppression. J Acquir Immune Defic Syndr 2019; 78:413-420.

Abstract
INTRODUCTION Gaps in Medicaid enrollment may affect HIV outcomes. We evaluated factors associated with Medicaid enrollment gaps and their effect on viral suppression (VS) within the HIV Research Network. METHODS We used a combined data set with Medicaid enrollment files from 2006 to 2010 and HIV Research Network demographic and clinical data. A gap was defined as ≥1 month without Medicaid and gap length was determined. We used multivariable logistic regression to determine factors associated with a gap and multivariable logistic regression with generalized estimated equations to evaluate factors associated with VS after gap. RESULTS Of 5836 participants, the majority were male, of black race, and aged 25-50 years. More than half had a gap in Medicaid. Factors associated with a gap included male sex [adjusted odds ratio (aOR) 1.79, (1.53, 2.08)] and younger age (aORs ranging from 1.50 to 4.13 comparing younger age groups to age >50, P < 0.05 for all). About a quarter of gaps had VS information before and after gap. Of those, 53.7% had VS both before and after gap and 25.8% were unsuppressed both before and after gap. The strongest association with VS after gap was VS before gap [aOR 15.76 (10.48, 23.69)]. Transition into Ryan White HIV/AIDS Program coverage during Medicaid gaps was common (28% of all transitions). CONCLUSIONS Gaps in Medicaid enrollment were common and many individuals with pre-gap VS maintained VS after gap, possibly due to accessing other sources of antiretroviral therapy coverage. Implementing initiatives to maintain Medicaid enrollment and to expedite Medicaid reenrollment and having alternate resources available in gaps are important to ensure continuous antiretroviral therapy to optimize HIV outcomes.

Abstract
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.

Abstract
Individuals who are at high risk of contracting HIV should have equitable access to preventive measures, such as pre-exposure prophylaxis (PrEP). We conducted a retrospective data extract from the electronic medical records of federally-qualified health centers in New York City from 2016 to 2018. Descriptive statistics are presented, stratified by those who have been prescribed PrEP and those who have not. We created a variable called "ever-female" which includes individuals assigned female at birth or who have ever identified as female. A chi-square test was performed to determine the statistical significance between variables as p < .05. A total of 9659 patients met inclusion criteria for the study. Patients who were prescribed PrEP were significantly associated with being white and never-female, with 38.2% of those prescribed PrEP identifying as white and 83.8% of those prescribed PrEP categorized as never-female. Patients of trans experience were 9.6% of the PrEP cohort and 1.5% of the never PrEP cohort (p < .001). Patients identifying as Black/African American made up 19.8% of patients prescribed PrEP and 49.8% of those never prescribed PrEP (p < .001). Patients with the lowest reported income composed 48.4% of those prescribed PrEP compared to 69.3% of patients who were never prescribed PrEP (p < .001). These findings indicate that key demographic categories may not be accessing PrEP as much as would be expected for their level of risk. Barriers to access of PrEP for women and other at-risk, under-represented populations should be further studied.

Abstract
OBJECTIVE African-American women are more likely than other women in the United States to experience poor HIV-related health; HIV stigma may contribute to these outcomes. This study assessed the relationship between HIV stigma and viral load, over time, among a sample of African-American women receiving treatment for HIV, and explored social support and depressive symptoms as mediators. DESIGN Secondary analysis of longitudinal data. METHODS Data came from a randomized trial of an intervention to reduce HIV stigma among African-American women in HIV care in Chicago, Illinois and Birmingham, Alabama. Sociodemographic and psychosocial data were collected at up to six study visits over 14 months. Viral loads were extracted from medical records during the study period. Generalized linear mixed effects models were used to estimate associations among overall, internalized, and enacted HIV stigma and viral load over time. Mediation analyses were used to estimate indirect effects via social support and depressive symptoms. RESULTS Data from 234 women were analyzed. Overall HIV stigma was significantly associated with subsequent viral load (adjusted β = 0.24, P = 0.005). Both between-subject (adjusted β = 0.74, P < 0.001) and within-subject (adjusted β = 0.34, P = 0.005) differences in enacted stigma were associated with viral load. Neither social support nor depressive symptoms were statistically significant mediators. CONCLUSION Ongoing experiences of HIV stigmatization may contribute to increased viral load among African-American women in primary HIV care. Interventions should aim to alleviate the consequences of stigma experienced by patients and prevent future stigmatization.

Abstract
The Ryan White HIV/AIDS program (RWHAP) provides essential primary and supplementary health services to people living with HIV (PLWH). We examined the relationship between supplementary RWHAP services (Part B) and two outcomes: viral suppression (VS) and two separate measures of retention in care (RiC) based on kept- and missed-visits. We used purposive sampling to identify adult patients who received primary medical care at an academically-affiliated HIV/AIDS clinic in the southeastern United States (N = 1159) and who attended at least one scheduled HIV primary care appointment at the study site during 2015. Unadjusted and adjusted logistic regression models were fit, in which RWHAP supplementary services were the primary independent variables of interest. Age, race, gender, education level, and income were control variables. Among 1159 PLWH, 45.3% received RWHAP supplementary services in addition to public insurance, private insurance, or primary RWHAP. Among participants, 91.4% were virally suppressed, 87.4% were retained in care using the Institute of Medicine (IOM) kept-visits measure, and 60% were retained in care using the missed-visits measure. In multivariable models, patients with RWHAP supplementary services had significantly higher odds of (1) VS [adjusted odds ratio (AOR) = 1.91], (2) RiC using the IOM kept-visits measure (AOR = 2.56), and (3) RiC using the missed-visits measure (AOR = 1.58). Receipt of supplementary RWHAP services is associated with increased odds of VS and two measures of RiC when adjusting for key sociodemographic variables. Policymakers should consider the vital role of RWHAP as continued funding is uncertain.

Abstract
Retention in care (RiC) is crucial for maintaining HIV health. We examined the relationship between receipt of Ryan White HIV/AIDS Program (RWHAP) supplementary services and six different measures of RiC among 2,288 adults living with HIV who received HIV primary care services at a large, academically-affiliated HIV/AIDS clinic in the southeastern United States in 2016. The independent variable of interest was RWHAP supplementary services, which referred to whether patients received documented non-medical wraparound supplementary services. The outcome was six different measures of RiC: the Institute of Medicine (IOM) indicator, 6-month gap, 4-month constancy, missed visits dichotomous, missed visits count, and visit adherence. Separate multivariable models were fit for each RiC outcome. Receipt of supplementary RWHAP services was significantly (p < .05) and positively associated with RiC across all six measures (test statistic, 95% confidence interval): IOM (adjusted odds ratio (aOR) = 2.88, 2.16-3.83), 6-month gap (aOR = 1.76, 1.48-2.09), 4-month visit constancy (aOR = 2.03, 1.72-2.39), missed visits dichotomous (aOR = 1.40, 1.16-1.68), missed visit count (adjusted incidence rate ratio (aIRR) = 0.77, 0.67-0.88), and visit adherence (adjusted beta coefficient (adjβ) = 0.05, 0.02-0.06). Our findings suggest that receipt of RWHAP services is important for retention in care, regardless of the measure employed.

Abstract
This study sought to evaluate the risk of homelessness among HIV positive users of Veterans Health Administration (VHA) services. National VHA administrative data from Fiscal Year (FY) 2012 (N = 5.4 million) were used to: (1) evaluate the unadjusted risk of homelessness among veterans with HIV; (2) identify common multi-morbid correlates of both HIV diagnosis and homelessness; and (3) to assess the independent risk of homelessness among veterans with HIV after adjusting for risk factors common to both conditions. Veterans with HIV were at substantial risk of homelessness (OR = 4.23 (95% CI 4.07-4.39)). However, with adjustment for shared co-variates (especially black race, low income, substance use, and psychiatric disorders) this risk declined substantially to 1.41 (95% CI 1.35-1.48). The high risk of homelessness among HIV positive veterans is largely attributable to multi-morbid risk factors common to both HIV and homelessness rather than to an independent effect of HIV, and requires multi-dimensional preventive psychosocial interventions.

Abstract
Ancillary service needs likely influence time to diagnosis and presentation for HIV care. The effect of both met and unmet needs on late presentation to HIV care is not well understood. We used baseline data from 348 people with HIV (PWH) with no prior HIV care who enrolled in iENGAGE (a randomized controlled trial (RCT) of an intervention to support retention in care) at one of four HIV clinics in the US. A standardized baseline questionnaire collected information on ancillary service needs, and whether each need was presently unmet. We examined covariates known to be associated with disease stage at presentation to care and their association with needs. We subsequently assessed the relationship of needs with CD4 accounting for those other covariates by estimating prevalence ratios (PR) using inverse probability weights. Most patients enrolling in the RCT were male (79%) and the majority were Black (62%); median age was 34 years. Prevalence of any reported individual need was 69%. One-third of the sample had a baseline CD4 cell count <200, 42% between 200 and 499 and 27% ≥500. There was no statistically significant association between need or unmet need and baseline CD4. In general, psychiatric health and SU issues (depression, anxiety, and drug use) were consistently associated with higher prevalence of need (met and unmet). Additionally, the Black race was associated with higher basic resource needs (housing: PR 1.67, 95%CI 1.08-2.59; transportation: PR 1.65, 95% CI 1.12-2.45). Ancillary service needs (met and unmet) were common among patients new to HIV care and impacted vulnerable subgroups. However, we found no evidence that reporting a specific individual need, whether met or unmet, was associated with a timely presentation to HIV care. The impact of needs on subsequent steps of the HIV care continuum will be examined with longitudinal data.

Abstract
The NC-LINK Project initiated both clinic-based retention services and state public health bridge counselor-based (SBCs) re-engagement services to retain and re-engage people living with HIV infection (PLWH) in care. The goal of this project is to compare efforts between clinic-based retention and SBC re-engagement services to determine whether patients are more or less likely to remain in HIV care services. Clinic appointment data were used to identify patients who were last seen more than 6-9 months prior. Patients either received clinic-based retention services only or were subsequently referred to the SBC re-engagement intervention if the retention services were unsuccessful. The frequency of re-engagement in care (180 days) and HIV suppression (VLS, within 1 year) was examined for patients in these two groups. The SBC group was less likely to have VLS at the visit prior to referral (adjusted OR 2.04, 95% CI 1.53, 2.72). Patients who were referred to the SBC were less likely to re-engage in care within 180 days as compared to those who received clinic-based retention services only (adjusted OR 0.29, 95% CI 0.21, 0.41).

Abstract
Background:
The use of Antiretroviral Therapy (ART) in HIV-infected persons has proven to be effective in the reduction of risk of disease progression and prevention of HIV transmission.
Objective:
U.S. Antiretroviral Therapy (ART) guidelines specify recommended initial, alternative initial, and not-recommended regimens, but data on ART prescribing practices and real-world effectiveness are sparse.
Methods:
Nationally representative annual cross sectional survey of HIV-infected adults receiving medical care in the United States, 2009-2012 data cycles. Using data from 18,095 participants, we assessed percentages prescribed ART regimens based on medical record documentation and the associations between ART regimens and viral suppression (most recent viral load test <200 copies/ml in past year) and ART-related side effects.
Results:
Among HIV-infected adults receiving medical care in the United States, 91.8% were prescribed ART; median time since ART initiation to interview date was 9.8 years. The percentage prescribed ART was significantly higher in 2012 compared to 2009 (92.7% vs 88.7%; p < 0.001). Of those prescribed ART, 51.6% were prescribed recommended initial regimens, 6.1% alternative initial regimens, 29.0% not-recommended as initial regimens, and 13.4% other regimens. Overall, 79.5% achieved viral suppression and 15.7% reported side effects. Of those prescribed ART and initiated ART in the past year, 80.5% were prescribed recommended initial regimens.
Conclusion:
Among persons prescribed ART, the majority were prescribed recommended initial regimens. Monitoring of ART use should be continued to provide ongoing assessments of ART effectiveness and tolerability in the United States.

Abstract
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.

Prevalence of HIV Viral Load Suppression Among Psychiatric Inpatients with Comorbid Substance Use Disorders. Community Ment Health J 2018; 54:1146-1153. [PMID: 29752639 PMCID: PMC6230497 DOI: 10.1007/s10597-018-0284-2] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/07/2017] [Accepted: 05/05/2018] [Indexed: 02/05/2023]
Abstract
A consistently suppressed viral load enables HIV (+) patients to live longer, healthier lives and reduces the probability of transmitting the virus. Since the prevalence of HIV is four times higher among those with psychiatric disorders than in the general population, it is likely that this group would also have greater difficulty remaining in care and achieving viral suppression. A secondary data analysis utilizing screening data from the Preventing AIDS Through Health (PATH) for Triples (PFT) Study were examined to assess HIV load suppression among 254 psychiatric inpatients with comorbid substance use disorders in Philadelphia. Viral load results from the past 12 months were obtained from medical records for 63 inpatients identified as HIV (+). The sample was predominately African American (76%), male (56%), and the average age was 43 years. Psychiatric disorders included depression (64%), schizophrenia (21%), and bipolar disorder (13%) with patients reporting use of alcohol (73%), cocaine (64%), cannabis (29%) and opioids (16%) prior to admission. Among this high risk sample of HIV (+) patients, about one-half (52%) achieved viral suppression, with recent opioid users six times more likely to have a detectable viral load than non-opioid users (OR 6.0; CI 1.1-31.7, p = .035). The 52% viral load suppression rate among psychiatric inpatient was higher than expected, given that the CDC's national suppression rate among those diagnosed with HIV in the general population is 58%. However, individuals with mental illness and substance use disorders require constant surveillance, monitoring, and supportive services to achieve viral suppression. Many of those who were virally suppressed were engaged in Philadelphia's extensive treatment network, whereas those who were detectable and enrolled in the PFT intervention were often homeless with unstable psychiatric symptoms and current substance use disorders, particularly opioid abuse.

Abstract
Unstable housing, including homelessness, is a public policy concern for all populations, and more critically for people with a serious health condition such as HIV. We measure the effect of unstable housing on HIV treatment biomarkers: viral suppression (viral load < 200 HIV RNA copies per ml) and adequate CD4+ T-cell count (CD4>350 cells per μl). We use panel data (1995-2015) from 3082 participants of the Women's Interagency HIV Study (WIHS) sites in Bronx and Brooklyn (NY), Chicago (IL), Los Angeles and San Francisco (CA), and Washington (DC). The instrumental variable (IV) measures allocations for the Housing Opportunities for People with AIDS (HOPWA) per person newly infected with HIV, and it represents actual availability of housing assistance for HIV-positive persons at the metropolitan area level. Using an extended probit model with the IV, we find that unstable housing reduces the likelihood of viral suppression by 51 percentage points, and decreases the probability of having adequate CD4 cell count by 53 percentage points. The endogeneity-corrected results are larger than naïve probits, which show decreases of 8.1 and 7.8 percentage points, respectively. The hypothesized pathways for the effect are: decreased use of mental healthcare/counseling, any healthcare, and less continuity of care. Increasing efforts to improve housing assistance, including HOPWA, and other interventions to make housing more affordable for low-income populations, and HIV-positive populations in particular, may be warranted not only for the benefits of stable housing, but also to improve HIV-related biomarkers.

Abstract
This study applying the health services utilization model examined the importance of predisposing, enabling, and need variables to the social mechanisms explaining lifetime HIV testing across racial/ethnic groups. Data for the study were derived from the National Health Interview Survey (collected 2013–2014), our final sample numbering 18,574 adults. Four subsamples reflected race/ethnicity: 13,347 Whites, 2267 Blacks, 2074 Hispanics, and 886 Asians. Logistic regression established respondent odds of ever having received HIV testing. Further statistical testing evaluated race/ethnicity’s potential moderating role in HIV testing. The findings generally support a role for Aday’s predisposing, enabling, and need factors in explaining HIV testing. Across the four subsamples, female gender, older age, and sexual minority status consistently increased lifetime HIV testing. However, we found racial/ethnic differences in HIV testing’s associations with these factors and others. Our study made a beginning in the effort to specify mechanisms leading to HIV testing—and reliable diagnosis—among four racial/ethnic groups. Understanding these mechanisms might multiply opportunities to raise testing rates for all, in turn reducing racial/ethnic disparities in HIV treatment.

Abstract
Syndemic theory seeks to understand the interactions and clustering of disease and social conditions and explain racial disparities in HIV. Traditionally applied to HIV risk, this study characterizes the syndemic challenges of engagement in care among Black men living with HIV and provides insight into potential HIV treatment interventions to retain vulnerable individuals in care. Interviews were conducted with 23 HIV-positive men who were either out-of-care or nonadherent to antiretroviral therapy (ART). Interviews were audio recorded, transcribed verbatim, and coded using MAXQDA qualitative software. Researchers analyzed data using thematic content analysis to identify syndemic factors associated with disengagement in care or suboptimal ART adherence among Black men. Analyses revealed the syndemic nature of four themes: intersectional stigma, depression, substance use, and poverty. Findings from this study offer numerous opportunities for intervention including social and structural-level interventions to address syndemic processes and the influence of stigma and poverty on engagement in care.

Abstract
Poor engagement into HIV care limits the effectiveness of highly active antiretroviral therapies (HAART) to improve survival and reduce transmission. The design of effective interventions to enhance linkage to care is dependent on evidence about rates of entry into HIV care. This is a systematic review and meta-analysis on linkage measurement and its determinants in the late era of HAART (post-2003), in high-income countries. We searched the PubMed and Web of Science databases, restricting our sample to the late HAART era (post-2003) until February 2016, and to high-income countries. We retained only studies that produced quantified outcomes. We rejected the studies with a high risk of bias, and followed a standard meta-analytic approach. Because there was a high heterogeneity ( I 2 > 90%), the aggregated findings were based on a random-effects model. A total of 43 studies were identified, all of them following a cohort of patients newly diagnosed until referred to specialized care. For a one-month period, the meta-proportion was 71.1% (IC95%: 61.0%-81.2). For a three-month duration, the meta-proportion of linkage to care was 77.0% (IC95%: 75.0%-79.0). For a one-year period, the meta-proportion was 76.3% (IC95%: 54.2%-98.4%). The proportions were lower when lab tests were used as referral indicator, with a pooled meta-proportion of 76.7% (IC95%: 73.0%-80.4), in comparison to a value of 80.8% (IC95%: 68.7%-92.9) for consultations. Being black or male were the most commonly observed determinants of delayed entry into care. Young people, injecting drug users, people with low socioeconomic status, or at a less advanced stage of disease also experienced lower proportions of timely linkage. Timely engagement into care is below 80% and specific sub-groups are particularly at risk of late entry. These findings confirm earlier evidence that linkage to care remains low, and that efforts should focus on vulnerable populations.

Abstract
Lifelong ART is essential to reducing HIV mortality and ending the epidemic, however the interplay between socioeconomic position and long-term outcomes of HIV-infected persons receiving antiretroviral therapy (ART) in sub-Saharan Africa is unknown. Furthering the understanding of factors related to long-term ART outcomes in this important region will aid the successful scale-up of ART programs. We enrolled 559 HIV-infected Ugandan adults starting ART in 2004-2005 at the Infectious Diseases Institute in Kampala, Uganda and followed them for 10 years. We documented baseline employment status, regular household income, education level, housing description, physical ability, and CD4 count. Viral load was measured every six months. Proportional hazard regression tested for associations between baseline characteristics and 1) mortality, 2) virologic failure, and 3) mortality or virologic failure as a composite outcome. Over ten years 23% (n = 127) of participants died, 6% (n = 31) were lost-to-follow-up and 23% (107/472) experienced virologic treatment failure. In Kaplan-Meier analysis we observed an association between employment and mortality, with the highest cumulative probability of death occurring in unemployed individuals. In univariate analysis unemployment and disease severity were associated with mortality, but in multivariable analysis the only association with mortality was disease severity. We observed an association between higher household income and an increased incidence of both virologic failure and the combined outcome, and an association between self-employment and lower incidence of virologic failure and the combined outcome when compared to unemployment. Formal education level and housing status were unrelated to outcomes. It is feasible to achieve good ten-year survival, retention-in-care, and viral suppression in a socioeconomically diverse population in a resource-limited setting. Unemployment appears to be related to adverse 10-year ART outcomes. A low level of formal education does not appear to be a barrier to successful long-term ART.

Abstract
BACKGROUND To track the HIV epidemic and responses to it, the World Health Organization recommends 10 global indicators to collect information along the HIV care cascade. Patient diagnosis and medical record data, harnessed through case-based surveillance (CBS), can be used to measure 8 of these. While many high burden countries have well-established systems for monitoring patients on HIV treatment, few have formally adopted CBS. OBJECTIVE In response to the need for improved strategic HIV information and to facilitate the development of CBS in resource-limited countries, we aimed to conduct situational assessments of existing data collection systems in Tanzania, South Africa, and Kenya. METHODS We developed a standardized protocol and a modularized data collection tool to be adapted for the particular focus of the assessments within each country. The three countries were selected based on their stage of readiness for CBS. The assessment included three parts: a desk review of relevant materials on HIV surveillance and program monitoring, stakeholder meetings, and site visits. RESULTS In all three countries, routine HIV program monitoring is conducted, and information on new HIV diagnoses and persons accessing HIV care and treatment services is collected. Key findings from the assessments included substantial stakeholder support for the development of CBS, significant challenges in linking data within and between systems, data quality, the ability to obtain data from multiple sources, and information technology infrastructure. Viral load testing capacity varied by country, and vital registry data were not routinely linked to health systems to update medical records. CONCLUSIONS Our findings support the development of CBS systems to systematically capture routinely collected health data to measure and monitor HIV epidemics and guide responses. Although there were wide variations in the systems examined, some of the current program and patient monitoring systems can be adapted to function effectively for CBS, especially if supported by an improved patient registration system with shared unique health identifiers.

Abstract
BACKGROUND Among low-income women with and without HIV, it is a priority to reduce age-related comorbidities, including hypertension and its sequelae. Because consistent health insurance access has been identified as an important factor in controlling many chronic diseases, we estimated the effects of coverage interruption on loss of hypertension control in a cohort of women in the United States. METHODS We analyzed prospective, longitudinal data from the Women's Interagency HIV Study. HIV-infected and HIV-uninfected women were included between 2005 and 2014 when they reported health insurance at consecutive biannual visits and had controlled hypertension, and were followed for any insurance break and loss of hypertension control. We estimated hazard ratios (HRs) by Cox proportional hazards regression with inverse-probability-of-treatment-and censoring weights (marginal structural models), and plotted the cumulative incidence of hypertension control loss. RESULTS Among 890 HIV-infected women, the weighted HR for hypertension control loss comparing health insurance interruption to uninterrupted coverage was 1.37 (95% confidence interval [CI], 0.99-1.91). Inclusion of AIDS Drug Assistance Program (ADAP) participation with health insurance modestly increased the HR (1.47; 95% CI, 1.04-2.07). Analysis of 272 HIV-uninfected women yielded a similar HR (1.39; 95% CI, 0.88-2.21). Additionally, there were indications of uninterrupted coverage having a protective effect on hypertension when compared with the natural course in HIV-infected (HR, 0.82; 95% CI, 0.61-1.11) and HIV-uninfected (HR, 0.78; 95% CI, 0.52-1.19) women. CONCLUSIONS This study provides evidence that health insurance continuity promotes hypertension control in key populations. Interventions that ensure coverage stability and ADAP access should be a policy priority.

Abstract
BACKGROUND Implementation of the Affordable Care Act motivates assessment of health insurance and supplementary programs, such as the AIDS Drug Assistance Program (ADAP) on health outcomes of HIV-infected people in the United States. We assessed the effects of health insurance, ADAP, and income on HIV viral load suppression. METHODS We used existing cohort data from the HIV-infected participants of the Women's Interagency HIV Study. Cox proportional hazards models were used to estimate the time from 2006 to unsuppressed HIV viral load (>200 copies/mL) among those with Medicaid, private, Medicare, or other public insurance, and no insurance, stratified by the use of ADAP. RESULTS In 2006, 65% of women had Medicaid, 18% had private insurance, 3% had Medicare or other public insurance, and 14% reported no health insurance. ADAP coverage was reported by 284 women (20%); 56% of uninsured participants reported ADAP coverage. After accounting for study site, age, race, lowest observed CD4, and previous health insurance, the hazard ratio (HR) for unsuppressed viral load among those privately insured without ADAP, compared with those on Medicaid without ADAP (referent group), was 0.61 (95% CI: 0.48 to 0.77). Among the uninsured, those with ADAP had a lower relative hazard of unsuppressed viral load compared with the referent group (HR, 95% CI: 0.49, 0.28 to 0.85) than those without ADAP (HR, 95% CI: 1.00, 0.63 to 1.57). CONCLUSIONS Although women with private insurance are most likely to be virally suppressed, ADAP also contributes to viral load suppression. Continued support of this program may be especially critical for states that have not expanded Medicaid.

Abstract
In the early 1980s, men who have sex with men (MSM) in San Francisco were one of the first populations to be affected by the human immunodeficiency virus (HIV) epidemic, and they continue to bear a heavy HIV burden. Once a rapidly fatal disease, survival with HIV improved drastically following the introduction of combination antiretroviral therapy in 1996. As a result, the ability of HIV-positive persons to move into and out of San Francisco has increased due to lengthened survival. Although there is a high level of migration among the general US population and among HIV-positive persons in San Francisco, in- and out-migration patterns of MSM in San Francisco have, to our knowledge, never been described. Understanding migration patterns by HIV serostatus is crucial in determining how migration could influence both HIV transmission dynamics and estimates of the HIV prevalence and incidence. In this article, we describe methods, results, and implications of a novel approach for indirect estimation of in- and out-migration patterns, and consequently population size, of MSM by HIV serostatus and race in San Francisco. The results suggest that the overall MSM population and all the MSM subpopulations studied decreased in size from 2006 to 2014. Further, there were differences in migration patterns by race and by HIV serostatus. The modeling methods outlined can be applied by others to determine how migration patterns contribute to HIV-positive population size and output from these models can be used in a transmission model to better understand how migration can impact HIV transmission.

Abstract
People living with human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS) often are uninsured or underinsured, and they may benefit from the Patient Protection and Affordable Care Act (PL 111-148) and its improved access to medical care. Safety net programs, such as AIDS Drug Assistance Programs (ADAP) funded through the Ryan White HIV/AIDS Program, which serve low-income people living with HIV, are incorporating Patient Protection and Affordable Care Act Marketplace-qualified health plans (QHPs) and helping to fund patients' participation. This changing landscape differs from state to state, and one main element contributing to the differing situations is whether a state elected to expand Medicaid. This review examines QHP enrollment of ADAP clients in Virginia, a Medicaid nonexpansion state, and explores some issues that affect people living with HIV in other Medicaid nonexpansion states. Virginia is a leader in the shift of ADAP healthcare delivery from direct medication provision to purchasing QHPs. Virginia ADAP clients accounted for approximately 2% of ADAP clients nationally, but they represent 17% of ADAP clients enrolled in QHPs nationwide. Ensuring good HIV care of the ADAP population is important to each patient's personal longevity, the public health, and the efficient use of healthcare dollars. As healthcare delivery models shift, the effects on patients and health outcomes achieved should be monitored, particularly for chronic diseases such as HIV.

Abstract
BACKGROUND Long-term HIV care and treatment engagement is required for maximal clinical and prevention benefits, but longitudinal care patterns are poorly understood. We used the last 10 years' worth of HIV surveillance data from North Carolina to describe longitudinal HIV care trajectories from diagnosis. METHODS We conducted a retrospective, population-based cohort study of all persons newly diagnosed with HIV in North Carolina between March 31, 2006 and March 31, 2015 (N = 16,207). We defined HIV care attendance in each 3-month and 6-month interval after diagnosis as the presence of viral load and/or CD4 records (care visit proxies) in the interval. We used group-based trajectory modeling to identify common care trajectories and baseline predictors thereof. RESULTS A predicted 26% of newly HIV-diagnosed persons showed consistently high care attendance over time; ∼16% exhibited steadily declining attendance; ∼26% showed consistently low attendance; ∼17% had initially weak attendance with an increase starting ∼1.5 year later; and ∼15% showed initially weak attendance with an increase starting ∼3 years later. Older age at diagnosis was protective against all suboptimal trajectories (with the "consistently high" pattern as referent), and being a man who has sex with men was protective against 3 of the 4 suboptimal patterns. CONCLUSIONS As measured by surveillance-based laboratory proxies, most newly HIV-diagnosed persons exhibited suboptimal care trajectories, but there was wide variation in the particular pathways followed. The insights provided by this analytical approach can help to inform the design of epidemic models and tailored interventions, with the ultimate goal of improving HIV care engagement and transmission prevention.

Abstract
Background In the United States, an estimated two-thirds of persons with human immunodeficiency virus (HIV) infection do not achieve viral suppression, including those who have never engaged in HIV care and others who do not stay engaged in care. Persons with an unsuppressed HIV viral load might experience poor clinical outcomes and transmit HIV. Objective The goal of the Re-engaging Surveillance-identified Viremic Persons (RSVP) project in San Francisco, CA, was to use routine HIV surveillance databases to identify, contact, interview, and reengage in HIV care persons who appeared to be out of care because their last HIV viral load was unsuppressed. We aimed to interview participants about their HIV care and barriers to reengagement. Methods Using routinely collected HIV surveillance data, we identified persons with HIV who were out of care (no HIV viral load and CD4 laboratory reports during the previous 9-15 months) and with their last plasma HIV RNA viral load >200 copies/mL. We interviewed the located persons, at baseline and 3 months later, about whether and why they disengaged from HIV care and the barriers they faced to care reengagement. We offered them assistance with reengaging in HIV care from the San Francisco Department of Public Health linkage and navigation program (LINCS). Results Of 282 persons selected, we interviewed 75 (26.6%). Of these, 67 (89%) reported current health insurance coverage, 59 (79%) had ever been prescribed and 45 (60%) were currently taking HIV medications, 59 (79%) had seen an HIV provider in the past year, and 34 (45%) had missed an HIV appointment in the past year. Reasons for not seeing a provider included feeling healthy, using alcohol or drugs, not having enough money or health insurance, and not wanting to take HIV medicines. Services needed to get to an HIV medical care appointment included transportation assistance, stable living situation or housing, sound mental health, and organizational help and reminders about appointments. A total of 52 (69%) accepted a referral to LINCS. Additionally, 64 (85%) of the persons interviewed completed a follow-up interview 3 months later and, of these, 62 (97%) had health insurance coverage and 47 (73%) reported having had an HIV-related care appointment since the baseline interview. Conclusions Rather than being truly out of care, most participants reported intermittent HIV care, including recent HIV provider visits and health insurance coverage. Participants also frequently reported barriers to care and unmet needs. Health department assistance with HIV care reengagement was generally acceptable. Understanding why people previously in HIV care disengage from care and what might help them reengage is essential for optimizing HIV clinical and public health outcomes.

Abstract
Stable housing is key to improving health outcomes for people living with HIV/AIDS. Though many formerly homeless HIV positive individuals reside in supportive housing, little research has examined biometric HIV health outcomes for residents of these programs. Through a community-based research partnership, this study analyzed secondary data from a Shelter Plus Care supportive housing program in Cincinnati, Ohio to examine the likelihood of participants achieving a healthy CD4 count (>500 cells/mm3) and viral suppression (viral load <200 copies/mL) while in supportive housing and to identify participant characteristics associated with these outcomes. The study sample was 86 participants who entered the program between 2008 and 2016, including 50 current residents and 36 exited participants. Participants' average length of stay in Shelter Plus Care was 35.2 months (range 3.2-108.1 months) during the study period. Bivariate analysis indicated statistically significant improvements on both outcome variables, with 45% of participants achieving a healthy CD4 count and 79% achieving viral suppression by program exit or most recent time point. Participants who had health insurance at intake and who had never been incarcerated were more likely to achieve viral suppression, and longer length of stay in the program was also positively associated with viral suppression. These results add to the literature on the relationship between housing conditions and HIV health outcomes by demonstrating that residence in supportive housing is associated with improvements in CD4 count and viral load for a sample of formerly homeless persons living with HIV/AIDS, two-thirds of whom had co-occurring physical health, mental health, or substance abuse problems. Further research collaborations should expand on these findings to examine the service packages that are associated with optimal HIV health outcomes for supportive housing residents.
