Mixed Methods Analysis of Telehealth Experience, Satisfaction, and Quality of Care During the COVID Pandemic Among Persons with HIV in Washington, DC.

The purpose of this study is to describe telehealth experiences and quality of HIV care provided to an urban population of people with HIV (PWH) in Washington, DC. We used self-reported survey data from a cohort of PWH in the DC Cohort longitudinal study linked to medical records (October 26, 2020-December 31, 2021). Analyses followed a mixed-methods approach, including prevalence estimates and multivariable logistic regression of telehealth use by demographic and HIV characteristics. We measured primary motivation, modes of engagement, and telehealth satisfaction. Qualitative responses to open-ended questions were coded using collaborative coding. A framework developed by the National Quality Forum (NQF) was applied to the results. Among 978 participants, 69% reported using telehealth for HIV care during the pandemic. High school graduates were less likely to use telehealth compared to those with college education (aOR 0.69, 95% CI 0.48, 0.98). PWH with > 1 co-morbid condition were more likely to use telehealth compared to those without (aOR 1.42, 95% CI 1.02, 1.95). The majority reported satisfaction with telehealth (81%). Qualitative analysis of telehealth satisfaction found that most responses were related to access to care and technology, effectiveness, and patient experience. PWH using telehealth during the pandemic were satisfied with their experience though use differed demographically. Telehealth was used effectively to overcome barriers to care engagement, including transportation, costs, and time. As we transition away from the emergency pandemic responses, it will be important to determine how this technology can be used in the future in an equitable manner to further strengthen HIV care engagement.

HIV care continuum outcomes among recently diagnosed people with HIV (PWH) in Washington, DC.

The Ending the HIV Epidemic initiative aims to decrease new HIV infections and promote test-and-treat strategies. Our aims were to establish a baseline of HIV outcomes among newly diagnosed PWH in Washington, DC (DC), a 'hotspot' for the HIV epidemic. We also examined sociodemographic and clinical factors associated with retention in care (RIC), antiretroviral therapy (ART) initiation and viral suppression (VS) among newly diagnosed PWH in the DC Cohort from 2011-2016. Among 455 newly diagnosed participants, 92% were RIC at 12 months, ART was initiated in 65% at 3 months and 91% at 12 months, VS in at least 17% at 3 months and 82% at 12 months and 55% of those with VS at 12 months had sustained VS for an additional 12 months. AIDS diagnosis was associated with RIC (aOR 2.99; 1.13-2.28), ART initiation by 3 months (aOR 2.58; 1.61-4.12) and VS by 12 months (aOR4.87; 1.69-14.03). This analysis contributes to our understanding of the HIV treatment dynamics of persons with recently diagnosed HIV infection in a city with a severe HIV epidemic.

Psychosocial impacts of the COVID-19 pandemic from a cross-sectional Survey of people living with HIV in Washington, DC.

BACKGROUND: COVID-19 has not only taken a staggering toll in terms of cases and lives lost, but also in its psychosocial effects. We assessed the psychosocial impacts of the COVID-19 pandemic in a large cohort of people with HIV (PWH) in Washington DC and evaluated the association of various demographic and clinical characteristics with psychosocial impacts. METHODS: From October 2020 to December 2021, DC Cohort participants were invited to complete a survey capturing psychosocial outcomes influenced by the COVID-19 pandemic. Some demographic variables were also collected in the survey, and survey results were matched to additional demographic data and laboratory data from the DC Cohort database. Data analyses included descriptive statistics and multivariable logistic regression models to evaluate the association between demographic and clinical characteristics and psychosocial impacts, assessed individually and in overarching categories (financial/employment, mental health, decreased social connection, and substance use). RESULTS: Of 891 participants, the median age was 46 years old, 65% were male, and 76% were of non-Hispanic Black race/ethnicity. The most commonly reported psychosocial impact categories were mental health (78% of sample) and financial/employment (56% of sample). In our sample, older age was protective against all adverse psychosocial impacts. Additionally, those who were more educated reported fewer financial impacts but more mental health impacts, decreased social connection, and increased substance use. Males reported increased substance use compared with females. CONCLUSIONS: The COVID-19 pandemic has had substantial psychosocial impacts on PWH, and resiliency may have helped shield older adults from some of these effects. As the pandemic continues, measures to aid groups vulnerable to these psychosocial impacts are critical to help ensure continued success towards healthy living with HIV.

Site assessment survey to assess the impact of the COVID-19 pandemic on HIV clinic site services and strategies for mitigation in Washington, DC.

INTRODUCTION: The COVID-19 pandemic has created substantial interruptions in healthcare presenting challenges for people with chronic illnesses to access care and treatment services. We aimed to assess the impact of the pandemic on HIV care delivery by characterizing the pandemic-related impact on HIV clinic-level services and the mitigation strategies that were developed to address them. METHODS: The data comes from a site assessment survey conducted in the DC Cohort, an observational clinical cohort of PWH receiving care at 14 HIV outpatient clinics in Washington, D.C. Frequency counts and prevalence estimates of clinic-level survey responses about the impact of care delivery, COVID-19 testing, and vaccinations and mitigation strategies are presented. RESULTS: Clinics reported an increase in temporary clinic closures (n = 2), reduction in clinic hours (n = 5), telehealth utilization (n = 10), adoption of multi-month dispensation of antiretroviral (ARV) medication (n = 11) and alternative drug delivery via postal/courier service, home/community delivery or pick-up (n = 11). Clinics utilized strategies for PWH who were lost to follow-up during the pandemic including offering care to persons with any income level and insurance status (n = 9), utilizing e-prescribing for auto refills even if the patient missed visits (n = 8), and utilization of the regional health information exchange to check for hospitalizations of PWH lost to follow-up (n = 8). Most social services offered before the pandemic remained available during the pandemic; however, some support services were modified. CONCLUSIONS: Our findings demonstrate the extent of pandemic-era disruptions and the use of clinic-level mitigation strategies among urban HIV clinics. These results may help prepare for future pandemic or public health emergencies that disrupt healthcare delivery and access.

Risk of Severe COVID-19 Disease and the Pandemic's Impact on Service Utilization Among a Longitudinal Cohort of Persons with HIV-Washington, DC.

People with HIV (PWH) have a high burden of medical comorbidities, potentially putting them at increased risk for severe COVID-19. Additionally, during the COVID-19 pandemic, HIV care delivery has been restructured and the impact on HIV outcomes is unknown. The objectives of this study were first, to examine the risk of severe COVID-19 among PWH, using a definition incorporating clinical risk factors, and second, to examine the pandemic's impact on HIV care. We used data from the DC Cohort, a large cohort of people receiving HIV care in Washington, DC. We found that a high proportion of participants across all age groups qualified as increased (58%) or high risk (34%) for severe COVID-19. Between 2019 and 2020, encounters increased (17.7%, increasing to 23.5% of active DC Cohort participants had an encounter) while laboratory utilization decreased (14.4%, decreasing to 11.4% of active DC Cohort participants had an HIV RNA test performed). Implications of our work include the importance of protecting vulnerable people with HIV from acquiring COVID-19 and potentially manifesting severe complications through strategies including vaccination. Additionally, acknowledging that HIV service delivery will likely be changed long-term by the pandemic, adaptation is required to ensure continued progress towards 90-90-90 goals.

Disrupting the Systems: Opportunities to Enhance Methodological Approaches to Address Socio-Structural Determinants of HIV and End the Epidemic Through Effective Community Engagement.

A world without HIV is only possible by addressing the socio-structural determinants of health. Our understanding of socio-structural determinants is constantly changing, and parallel changes must occur with the methodologies used to explain the drivers of the HIV epidemic. We argue for the need to engage communities in the planning, implementation, and dissemination of research on the socio-structural determinants of HIV. Community engagement should cross-cut various types of research including rigorous measurement development of socio-structural determinants and novel analytic techniques to model their role in the trajectory of the epidemic and the impact of interventions. Considering the role of place, we recommend collaboration between scientists and communities in the interpretation of results from studies that map HIV-related behaviors and movement. As we collectively delve into historically oppressive systems with colonial antecedents, we must be ready to challenge these systems and replace them with collaborative models. The success of research-driven HIV policy and programming will best be evaluated with methodologies derived from the insights of the very individuals that these policies and programs aim to serve.

RESUMEN: Un mundo sin VIH es posible sólo si atendemos los determinantes socio-estructurales de la salud. Nuestra comprensión sobre determinantes socio-estructurales cambia constantemente y cambios similares deben ocurrir en las metodologías utilizadas para explicar los factores que rigen la epidemia del VIH. Argumentamos sobre la necesidad de involucrar las comunidades en la planificación, implementación y diseminación de investigaciones sobre los determinantes socio-estructurales del VIH. La participación comunitaria debe ser transversal en varios tipos de investigaciones, incluyendo el desarrollo riguroso de métricas sobre los determinantes socio-estructurales y técnicas noveles para la modelación de su rol en las trayectorias de la epidemia y el impacto de intervenciones. Considerando el rol que tiene el lugar físico, recomendamos la colaboración de científicos y comunidades en la interpretación de resultados de estudios que crean mapas de las conductas relacionadas al VIH y la movilidad de las personas. En la medida en que examinamos sistemas históricamente opresivos con antecedentes coloniales, debemos estar listos para retar estos sistemas y remplazarlos con modelos colaborativos. El logro de políticas y programas de VIH informados por la investigación sería evaluado mejor si se utilizan metodologías guiadas por el conocimiento de las personas a las cuales estas políticas y programas persiguen servir.

Diabetes mellitus control in a large cohort of people with HIV in care-Washington, D.C.

With more effective antiretroviral therapy (ART), people with HIV (PWH) are living longer and have more chronic diseases, including diabetes mellitus (DM). The prevalence of DM has been estimated in PWH previously, however there is less research regarding DM control. Our objectives were to determine the prevalence of DM and DM control and determine factors associated with DM control in a large urban cohort of PWH in care. We examined DC Cohort participants aged ≥18 years old to determine DM prevalence and to assess DM control (HbA1c measurement <7.0%). Demographic, clinical, and HIV-related factors associated with DM control were identified using multivariate logistic regression. The cohort of 5876 participants was predominantly male (71.3%), Non-Hispanic Black (78.1%) and had a median age of 52.0 years. DM prevalence was 17.4% (1023/5876). Among participants with recent HbA1c data available (39.9%) the proportion with DM control was 60.0% (245/408). In multivariate analysis, higher BMI (aOR: 0.47; 95% CI 0.28, 0.79) and use of non-insulin DM medication (aOR 0.43, 95% CI 0.25, 0.73) or insulin (aOR 0.010, 95% CI 0.04,0.24) compared to no medication use. Our findings suggest that individuals on medication for their DM likely need enhanced support to reach their treatment goals.

Clinic-Level Factors Associated With Time to Antiretroviral Initiation and Viral Suppression in a Large, Urban Cohort.

BACKGROUND: Using the results of a site assessment survey performed at clinics throughout Washington, DC, we studied the impact of clinic-level factors on antiretroviral therapy (ART) initiation and viral suppression (VS) among people living with human immunodeficiency virus (HIV; PLWH). METHODS: This was a retrospective analysis from the District of Columbia (DC) Cohort, an observational, clinical cohort of PLWH from 2011-2018. We included data from PLWH not on ART and not virally suppressed at enrollment. Outcomes were ART initiation and VS (HIV RNA < 200 copies/mL). A clinic survey captured information on care delivery (eg, clinical services, adherence services, patient monitoring services) and clinic characteristics (eg, types of providers, availability of evenings/weekends sessions). Multivariate marginal Cox regression models were generated to identify those factors associated with the time to ART initiation and VS. RESULTS: Multiple clinic-level factors were associated with ART initiation, including retention in care monitoring and medication dispensing reviews (adjusted hazard ratios [aHRs], 1.34 to 1.40; P values < .05 for both). Furthermore, multiple factors were associated with VS, including retention in HIV care monitoring, medication dispensing reviews, and the presence of a peer interventionist (aHRs, 1.35 to 1.72; P values < .05 for all). In multivariable models evaluating different combinations of clinic-level factors, enhanced adherence services (aHR, 1.37; 95% confidence interval [CI], 1.18-1.58), medication dispensing reviews (aHR, 1.22; 95% CI, 1.10-1.36), and the availability of opioid treatment (aHR, 1.26; 95% CI, 1.01-1.57) were all associated with the time to VS. CONCLUSIONS: The observed association between clinic-level factors and ART initiation/VS suggests that the presence of specific clinic services may facilitate the achievement of HIV treatment goals.

Influence of support-layer deformation on the intrinsic resistance of thin film composite membranes.

It is commonly believed that the overall permeation resistance of thin film composite (TFC) membranes is dictated by the crosslinked, ultrathin polyamide barrier layer, while the porous support merely serves as the mechanical support. Although this assumption might be the case under low transmembrane pressure, it becomes questionable under high transmembrane pressure. A highly porous support normally yields under a pressure of a few MPa, which can result in a significant level of compressive strain that may significantly increase the resistance to permeation. However, quantifying the influence of porous support deformation on the overall resistance of the TFC membrane is challenging. In particular, it is difficult to determine the deformation/strain of the membrane during active separation. In this study, we use nanoimprint lithography (NIL) to achieve precise compressive deformation in commercial TFC membranes. By adjusting the NIL conditions, membranes were compressed to strain levels up to 60%. SEM and AFM measurements showed that the compression had minimal impact on the barrier-layer surface morphology and total surface area with most of the deformation occurring in the support layer. DI water permeation measurements revealed that the water flux reduction decreases with an increase of strain level. Most significantly, the intrinsic membrane resistance showed negligible changes at strain levels lower than 30%-40%, but increased exponentially at higher strain levels, reaching 250%-500% of pristine (unstrained) membrane values. Using a resistance-in-series model, the strain dependency of the TFC membrane resistance can be described.

Hospitalized burden and outcomes of coccidioidomycosis: A nationwide analysis, 2005-2012.

The incidence of coccidioidomycosis (CM) infection has increased over the last 20 years. We investigated recent trends of CM-associated hospitalization in the United States. patients with CM-associated hospitalization were identified from the Nationwide Inpatient Sample, 2005-2012. The outcomes of interest were the trend of annual hospitalization, in-hospital mortality, and independent risk factors for mortality. A total of 30,870 hospitalizations with CM (29,584 of adults; 1,286 of children) were identified. Over the 8-year study period, the number of hospitalizations for CM fluctuated but increased overall with successively higher peaks in 2009 and 2011. The annual median length of stay (LOS) shortened from 6 to 7 days in 2005-2010 to 4 days in 2011 and 5 days in 2012. The inflation-adjusted hospital charges were highest in 2006 then trended down by 21% in 2012. The in-hospital mortality declined from the highest level in 2005 (5.2%) to a low in 2010 (1.1%), then increased modestly in 2011 (1.9%) and 2012 (1.5%). Hospitalizations were identified in 46 states, with nearly half in Arizona (49.1%), followed by California (36.8%), Texas (3.3%), and Nevada (1.6%). Logistic regression analysis in adults revealed that in-hospital mortality was associated with age groups 61-70 years and >70 years (OR = 3.3 and 3.5, respectively. Ref: 18-30 years) and Charlson Index ≥1 (OR = 2.0-8.3). In children, males had lower risk for mortality than females (OR = 0.2). This study shows that CM-associated hospitalizations occur widely throughout the United States with an increasing admission trend; however, patient outcomes have improved and the cost of hospitalization has decreased.

Disparities in achieving and sustaining viral suppression among a large cohort of HIV-infected persons in care - Washington, DC.

One goal of the HIV care continuum is achieving viral suppression (VS), yet disparities in suppression exist among subpopulations of HIV-infected persons. We sought to identify disparities in both the ability to achieve and sustain VS among an urban cohort of HIV-infected persons in care. Data from HIV-infected persons enrolled at the 13 DC Cohort study clinical sites between January 2011 and June 2014 were analyzed. Univariate and multivariate logistic regression were conducted to identify factors associated with achieving VS (viral load < 200 copies/ml) at least once, and Kaplan-Meier (KM) curves and Cox proportional hazards models were used to identify factors associated with sustaining VS and time to virologic failure (VL ≥ 200 copies/ml after achievement of VS). Among the 4311 participants, 95.4% were either virally suppressed at study enrollment or able to achieve VS during the follow-up period. In multivariate analyses, achieving VS was significantly associated with age (aOR: 1.04; 95%CI: 1.03-1.06 per five-year increase) and having a higher CD4 (aOR: 1.05, 95% CI 1.04-1.06 per 100 cells/mm(3)). Patients infected through perinatal transmission were less likely to achieve VS compared to MSM patients (aOR: 0.63, 95% CI 0.51-0.79). Once achieved, most participants (74.4%) sustained VS during follow-up. Blacks and perinatally infected persons were less likely to have sustained VS in KM survival analysis (log rank chi-square p ≤ .001 for both) compared to other races and risk groups. Earlier time to failure was observed among females, Blacks, publically insured, perinatally infected, those with longer standing HIV infection, and those with diagnoses of mental health issues or depression. Among this HIV-infected cohort, most people achieved and maintained VS; however, disparities exist with regard to patient age, race, HIV transmission risk, and co-morbid conditions. Identifying populations with disparate outcomes allows for appropriate targeting of resources to improve outcomes along the care continuum.

Increasing Volume but Decreasing Mortality of Hospitalized Hepatitis C Patients in the United States, 2005 to 2011.

BACKGROUND: Patients with hepatitis C virus infection often require hospitalization for progressive liver disease and complications, incurring high cost and risk of death. GOALS: The aim of our study was to investigate recent trends in the economic burden and outcomes of patients hospitalized for hepatitis C in the United States. STUDY: Patients with hepatitis C-associated hospitalization were identified from the Nationwide Inpatient Sample 2005 to 2011. We analyzed the in-hospital mortality, hospital service utilization, demographic, and clinical features of patients. A prognostic model to predict in-hospital survival and death with independent risk factors for mortality was developed. RESULTS: A total of 607,279 cases of hepatitis C-associated hospitalization were identified. Over 7 years, the annual hospitalized volume increased by 28.8%. In-hospital mortality declined from 8.2% to 6.4%. Median length of stay (4 d) was unchanged but the inflation-adjusted hospital charges increased by 33.3%. Acute respiratory failure was the greatest independent risk factor for mortality [odds ratio (OR)=7.3; 95% confidence interval (CI), 7.0-7.5], followed by septicemia (OR=4.1; 95% CI, 4.0-4.3), renal failure (OR=3.4; 95% CI, 3.3-3.5), and acute liver failure (OR=2.9; 95% CI, 2.7-3.0). On the basis of the major risk factors for mortality, a risk-adjusted model was developed that could predict the in-hospital outcome of hepatitis C patients with an accurate rate of 89.2%. CONCLUSIONS: Despite decreasing in-hospital mortality, both hospital volume and charges related to hepatitis C increased from 2005 to 2011. Use of a risk-adjusted model could help predict mortality and improve outcomes of hepatitis C inpatients.

Use of geosocial networking (GSN) mobile phone applications to find men for sex by men who have sex with men (MSM) in Washington, DC.

Current advances have added geosocial networking (GSN) mobile phone applications as an option for men who have sex with men (MSM) to meet other men. This is the first study to assess GSN application use and sex-seeking behaviors of MSM recruited using venue-based sampling. Among the 379 MSM in this study, 63.6 % reported using GSN applications to find men in the past year. Nearly one-quarter of MSM had sex with a man met using a GSN application in the prior year; these men were more likely to be under 35 years old and have had sex with a man met on the Internet; they were also less likely to be HIV-positive and have <5 male sex partners in the last year. GSN applications are a viable option for use in sampling and delivering interventions to young MSM who are often missed through other methods.

Correlates of group sex among a community-based sample of men who have sex with men (MSM) in Washington, DC.

Participation of MSM in group sex events (GSEs) is an understudied phenomenon. Studies on GSEs identified significant proportions of MSM engaging in unprotected anal intercourse (UAI). We sought to identify the prevalence of group sex participation among MSM in Washington, DC and to characterize these experiences. Data were collected for NHBS-MSM-3 in 2011. More than one-quarter of MSM (27.2 %) reported engaging in group sex in the prior year, with one-third reporting no condom use with their sex partners (33.0 %). In multivariable logistic regression, men who participated in a GSE in the prior year were significantly younger, more likely to be white, and to have used crystal meth, poppers, and downers in the past year. The high prevalence of UAI during GSEs, especially in view of the fact that HIV-positive MSM were significantly less likely to report condom use, offers an opportunity to develop risk reduction interventions specific to GSE attendees.

HIV among women in the District of Columbia: an evolving epidemic?

The epidemiology of HIV in urban centers of the United States such as the District of Columbia (DC) is dynamic with rates of new HIV and AIDS diagnoses as well as risk factors elevated. Correlates of HIV among heterosexual women extend beyond traditional, individual risk factors to structural factors. The purpose of this study was to compare proportions of HIV and correlates of HIV among women participating in National HIV behavioral surveillance (NHBS) system in 2006-7 (NHBS Cycle 1) and 2010 (NHBS Cycle 2). Analysis of 677 female participants at elevated risk for HIV revealed high prevalence of individual-level HIV-associated risk factors (e.g., sexual behavior) and socio-structural associated risk factors (e.g., homelessness, incarceration, lack of health insurance). While a greater proportion of women were HIV-infected in Cycle 2, after controlling for the distribution of demographic characteristics to adjust for a change in eligibility criteria, the pooled sample did not reveal a significantly increased proportion of HIV-infected women in Cycle 2. Homelessness and condom use were associated with greater relative odds of HIV after adjustment for confounders, and non-injection drug use was associated with reduced odds. Findings inform our understanding of the continuing HIV epidemic in DC and support development of effective interventions to slow the epidemic among women in DC and similar urban centers.

HIV testing among heterosexuals at elevated risk for HIV in the District of Columbia: has anything changed over time?

The District of Columbia launched a routine HIV testing initiative in 2006. We examined HIV testing behaviors among heterosexuals at risk for HIV over time using CDC National HIV Behavioral Surveillance data from Washington, DC for the heterosexual cycles from 2006 to 2007 (Cycle 1) and 2010 (Cycle 2). Past year and past 2-year HIV testing across study cycles were compared using Chi square tests. Weighted multivariable logistic regression identified correlates of past year testing. The majority of participants across both cycles were black and female. Cycle 1 participants were significantly more likely to have ≥4 partners in the past year, casual sex partners, and have anal sex at last sexual encounter (p < 0.05). Lifetime testing was high, and individuals from Cycle 2 versus Cycle 1 were more likely to have been tested in the past 2 years. There were no significant differences in past year testing or being offered the HIV test at last health care visit by cycle. Independent correlates of past year testing were seeing a health care provider in the past year and using condoms at last vaginal sex. In conclusion, although past year testing did not differ between the two data collection years, the proportion of heterosexuals testing in the past 2 years was higher in Cycle 2 versus Cycle 1, suggesting successful expansion of HIV testing between the two time periods.

Temporal association between expanded HIV testing and improvements in population-based HIV/AIDS clinical outcomes, District of Columbia.

In 2006, the District of Columbia Department of Health (DC DOH) launched initiatives promoting routine HIV testing and improved linkage to care in support of revised the Centers for Disease Control and Prevention (CDC) HIV-testing guidelines. An ecological analysis was conducted using population-based surveillance data to determine whether these efforts were temporally associated with increased and earlier identification of HIV/AIDS cases and improved linkages to care. Publically funded HIV-testing data and HIV/AIDS surveillance data from 2005 to 2009 were used to measure the number of persons tested, new diagnoses, timing of entry into care, CD4 at diagnosis and rates of progression to AIDS. Tests for trend were used to determine whether statistically significant changes in these indicators were observed over the five-year period. Results indicated that from 2005 to 2009, publically funded testing increased 4.5-fold; the number of newly diagnosed HIV/AIDS cases remained relatively constant. Statistically significant increases in the proportion of cases entering care within three months of diagnosis were observed (p < 0.0001). Median CD4 counts at diagnosis increased over the five-year time period from 346 to 379 cells/µL. The proportion of cases progressing from HIV to AIDS and diagnosed with AIDS initially, decreased significantly (both p < 0.0001). Routine HIV testing and linkage to care efforts in the District of Columbia were temporally associated with earlier diagnoses of cases, more timely entry into HIV-specialized care, and a slowing of HIV disease progression. The continued use of surveillance data to measure the community-level impact of other programmatic initiatives including test and treat strategies will be critical in monitoring the response to the District's HIV epidemic.

Childhood sexual abuse and HIV-related risks among men who have sex with men in Washington, DC.

Childhood sexual abuse (CSA) has been reported to be disproportionately higher among men who have sex with men (MSM) than among heterosexual men; it has also been found to be significantly positively associated with HIV status and HIV risk factors, including unprotected anal intercourse. The purpose of this study was to assess the correlates of CSA in a sample of community-recruited MSM, investigate race as a potential effect modifier, and describe the independent association between CSA and HIV infection in Washington, DC. A total of 500 MSM were recruited by venue-based sampling in 2008 as part of the National HIV Behavioral Surveillance. More than one-half of MSM identified as White, while one-third identified as Black. CSA was reported by 17.5 % of the 451 MSM, with the first instance of abuse occurring at a median age of 8.3 (interquartile range = 5.0, 11.0). In multivariable analysis, HIV-positive men were significantly more likely to report a history of CSA compared to HIV-negative men after adjusting for intimate partner violence in the last 12 months, having been arrested in the last 12 months, and depressive symptoms. HIV-positive MSM had more than four times the odds of reporting CSA after controlling for other correlates (aOR = 4.19; 95 % CI 2.26, 7.75). Despite hypothesizing that race modified the effect of CSA on HIV infection we found this was not the case in this sample. More research is needed to investigate the potential pathway between a history of CSA and HIV infection, and how this contributes to driving the HIV epidemic among MSM in Washington, DC.

Mpox Awareness, Risk Reduction, and Vaccine Acceptance among People with HIV in Washington, DC.

People with HIV (PWH) are disproportionally affected by mpox and at risk of severe complications. We assessed mpox knowledge, adoption of preventive behaviors, and vaccination attitudes among PWH enrolled in a longitudinal HIV cohort in Washington, DC, the DC Cohort. We conducted uni- and multivariable analyses comparing participants by vaccination status and HIV risk group, and multinomial regression to identify factors associated with vaccine acceptance. Among 430 PWH, 378 (87.9%) were aware of mpox. Among 373 participants with vaccination status data, 101 (27.1%) were vaccinated, 129 (34.6%) planned to vaccinate, and 143 (38.3%) did not plan to vaccinate. The three vaccination groups differed significantly by age, race, education, HIV risk group, recent STI status, and level of mpox worry (all p < 0.05). A higher proportion of men who have sex with men (MSM) reported limiting their number of sexual partners compared to non-MSM (p < 0.0001). Multinomial regression models comparing vaccinated to unvaccinated PWH found age, education, mode of HIV transmission/gender, and survey period were significantly associated with vaccination status (all p < 0.05). High levels of mpox awareness were observed among this cohort of PWH with more MSM employing risk reduction behaviors and being vaccinated. Ensuring that PWH, regardless of gender, sexual orientation, or age, understand the risks of mpox may improve vaccination uptake.

Factors associated with time to initial antiretroviral regimen discontinuation in the DC Cohort.

BACKGROUND: When an initial antiretroviral (ART) regimen is effective and well-tolerated, it can be maintained for years as long as the patient adheres. Prior research has revealed that shorter initial ART duration is associated with regimen type, female sex, injection drug use (IDU) as the HIV transmission risk factor, and lower baseline CD4 count. We examined initial ART duration in ART-naïve individuals newly enrolling in HIV care in the DC Cohort. METHODS: We included ART naïve-individuals with detectable HIV RNA enrolled in the DC Cohort after January 2011 with >6 months of follow-up. The outcome of interest was the discontinuation of the initial regimen. Kaplan Meier analysis and Multivariable Cox PH modeling were performed. RESULTS: There were 479 individuals included in the analysis. The median age of participants was 33.9 years (IQR 26-43.9). The sample was predominantly male (79.1%) and of Black race (70.8%). Over half of the study participants (56.4%) attended community-based clinic sites. The median time to the discontinuation of initial ART was 2.7 years (95% CI: 2.3, 3.4). Females had a shorter time to ART discontinuation (aHR 1.55, 95% CI: 1.14, 2.11) as did individuals who started on a PI-based regimen vs INSTI (aHR 1.87, 95% CI: 1.34, 2.61), and those receiving HIV care at a community-based site (aHR 1.46, 95% CI: 1.11,1.93). CONCLUSIONS: Although limited by lack of reason for discontinuation, we demonstrated that ART-naïve women, community clinic attendees, and patients starting on PIs had shorter duration of initial ART. More anticipatory guidance may be needed to help patients stay on their initial therapy and manage the side effects or to be flexible in trying different regimens.
