Estimating the Proportion of People Living With HIV Who May Benefit From the Reverse Algorithm for the Diagnosis of Incident Syphilis.

ABSTRACT: Among 8455 people engaged in HIV care in 4 US cities, 4925 (58%) had treponemal testing at care entry. Of the 4925 tested, 3795 (77%) had a nonreactive result and might benefit from the reverse algorithm for a future incident syphilis diagnosis. Furthermore, low-barrier treponemal testing as a first step in the reverse algorithm may increase syphilis screening and decrease time to treatment.

Predictors of Viral Suppression Among People Living with HIV in Rural Oregon.

With recent outbreaks of HIV in rural areas of the United States, it has become increasingly important to understand the factors affecting health outcomes of people with HIV living in rural areas. We assessed predictors of durable HIV viral suppression among rural participants using a pooled 7-year dataset from the Medical Monitoring Project (MMP), a cross-sectional, representative sample of individuals receiving HIV medical care in Oregon. Only 77.3% of rural participants achieved durable HIV viral suppression, while 22.7% had at least one detectable HIV viral load measurement within the past 12 months. The primary predictors of viral suppression were ARV adherence, poverty, and reported heavy drinking in the past 30 days. These results highlight the influence of social factors on health outcomes for persons with HIV living in rural areas and inform areas for policy and program change.

RESUMEN: Con los brotes recientes de VIH en áreas rurales de los Estados Unidos, se ha vuelto cada vez más importante comprender los factores que afectan los resultados de salud de las personas con VIH que viven en áreas rurales. Evaluamos los predictores de la supresión viral del VIH duradera entre los participantes rurales utilizando un conjunto de datos combinados de siete años del Proyecto de Monitoreo Médico (MMP), una muestra transversal y representativa de personas que reciben atención médica para el VIH en Oregón. Solo el 77,3% de los participantes rurales logró una supresión viral del VIH duradera, mientras que el 22,7% tuvo al menos una medición detectable de la carga viral del VIH en los últimos 12 meses. Los predictores primarios de la supresión viral fueron la adherencia a los ARV, la pobreza y el consumo excesivo de alcohol informado en los últimos 30 días. Estos resultados destacan la influencia de los factores sociales en los resultados de salud de las personas con VIH que viven en áreas rurales e informan las áreas para el cambio de políticas y programas.

The Ongoing Impact of COVID-19 on Testing for and Diagnoses of HIV and Bacterial Sexually Transmitted Infections in Oregon.

BACKGROUND: The COVID-19 pandemic has disrupted HIV and sexually transmitted infection (STI) testing accessibility. We sought to assess the longer-term impacts of COVID-19 on HIV and STI testing and diagnosis in Oregon. METHODS: First, we examined HIV, Neisseria gonorrhoeae / Chlamydia trachomatis (CT), and syphilis tests conducted at the Oregon State Public Health Laboratory (public sector) and a large commercial laboratory (private sector) and HIV, N. gonorrhoeae , CT, and primary and secondary (P&S) syphilis diagnoses in Oregon from January 1, 2019, to December 31, 2021. We compared monthly testing and diagnosis rates in 5 prespecified periods: pre-COVID-19 (January 2019-February 2020), stay-at-home order (March 2020-May 2020), reopening (June 2020-December 2020), vaccine availability (January 2021-June 2021), and Delta/early Omicron spread (July 2021-December 2021). Second, we calculated the number of HIV and STI diagnoses per test in the public and private sectors. Finally, we used seasonal autoregressive integrated moving average models to predict expected HIV and STI diagnoses for comparison to those observed. RESULTS: Both public and private sector HIV and bacterial STI testing fell to nadirs in April 2020 with incomplete recovery to 2019 levels by the close of 2021. Compared with pre-COVID-19, public sector and private sector testing was significantly lower in all subsequent periods. Compared with pre-COVID-19, P&S syphilis cases were 52%, 75%, and 124% greater in the reopening, vaccine availability, and Delta/early Omicron periods, respectively. From March 2020 to December 2021, we observed an excess of P&S syphilis cases (+37.1%; 95% confidence interval, 22.2% to 52.1%) and a deficit in CT cases (-10.7%; 95% confidence interval, -15.4% to -6.0%). CONCLUSIONS: By December 2021, HIV/STI testing had not recovered to pre-COVID-19 levels, and HIV/STI continues to be underdiagnosed. Despite decreased testing, P&S syphilis cases have increased substantially.

Syphilis Testing and Diagnosis Among People With Human Immunodeficiency Virus (HIV) Engaged in Care at 4 US Clinical Sites, 2014-2018.

BACKGROUND: Despite rising rates of syphilis among people with human immunodeficiency virus (HIV; PWH) in the United States, there is no optimal syphilis screening frequency or prioritization. METHODS: We reviewed records of all PWH in care between 1 January 2014 and 16 November 2018 from 4 sites in the Centers for AIDS Research Network of Integrated Clinical Systems Cohort (CNICS; N = 8455). We calculated rates of syphilis testing and incident syphilis and used Cox proportional hazards models modified for recurrent events to examine demographic and clinical predictors of testing and diagnosis. RESULTS: Participants contributed 29 568 person-years of follow-up. The rate of syphilis testing was 118 tests per 100 person-years (95% confidence interval [CI]: 117-119). The rate of incident syphilis was 4.7 cases per 100 person-years (95% CI: 4.5-5.0). Syphilis diagnosis rates were highest among younger cisgender men who have sex with men and transgender women, Hispanic individuals, people who inject drugs, and those with detectable HIV RNA, rectal infections, and hepatitis C. CONCLUSIONS: We identified PWH who may benefit from more frequent syphilis testing and interventions for syphilis prevention.

Metrics of Sexual Behavior Stigma Among Cisgender Men Who Have Sex With Men in 9 Cities Across the United States.

Men who have sex with men (MSM) in the United States are stigmatized for their same-sex practices, which can lead to risky sexual behavior, potentiating risk for human immunodeficiency virus (HIV) infection. Improved measurement is necessary for accurately reporting and mitigating sexual behavior stigma. We added 13 sexual behavior stigma items to local surveys administered in 2017 at 9 sites in the Centers for Disease Control and Prevention's National HIV Behavioral Surveillance system, which uses venue-based, time-sampling procedures to survey cisgender MSM in US Census Metropolitan Statistical Areas. We performed exploratory factor analytical procedures on site-specific (Baltimore, Maryland; Denver, Colorado; Detroit, Michigan; Houston, Texas; Nassau-Suffolk, New York; Portland, Oregon; Los Angeles, California; San Diego, California; and Virginia Beach-Norfolk, Virginia) and pooled responses to the survey items. A 3-factor solution-"stigma from family" (α = 0.70), "anticipated health-care stigma" (α = 0.75), and "general social stigma" (α = 0.66)-best fitted the pooled data and was the best-fitting solution across sites. Findings demonstrate that MSM across the United States experience sexual behavior stigma similarly. The results reflect the programmatic utility of enhanced stigma measurement, including tracking trends in stigma over time, making regional comparisons of stigma burden, and supporting evaluation of stigma-mitigation interventions among MSM across the United States.

Differing Correlates of Incident Bacterial Sexually Transmitted Infections Among a Cohort of Black Cisgender Men Who Have Sex With Men and Transgender Women Recruited in 6 US Cities (HIV Prevention Trials Network 061).

ABSTRACT: Compared with Black cisgender men who have sex with men (MSM), Black transgender women had a higher incidence of bacterial sexually transmitted infections (25.9 [11.1-46.3] vs. 9.6 [8.10-11.3] per 100 person-years), higher rates of income and housing insecurity, and condomless receptive anal intercourse. Further investigation of unique risk pathways among transgender women is critical.

Associations between HIV testing and multilevel stigmas among gay men and other men who have sex with men in nine urban centers across the United States.

BACKGROUND: Complex manifestation of stigma across personal, community, and structural levels and their effect on HIV outcomes are less understood than effects in isolation. Yet, multilevel approaches that jointly assesses HIV criminalization and personal sexual behavior stigma in relation to HIV testing have not been widely employed or have only focused on specific subpopulations. The current study assesses the association of three types of MSM-related sexual behavior-related stigma (family, healthcare, general social stigma) measured at both individual and site levels and the presence/absence of laws criminalizing HIV transmission with HIV testing behaviors to inform HIV surveillance and prevention efforts among HIV-negative MSM in a holistic and integrated way. METHODS: We included nine National HIV Behavioral Surveillance (NHBS) 2017 sites: Baltimore, MD; Denver, CO; Detroit, MI; Houston, TX; Long Island/Nassau-Suffolk, NY; Los Angeles, CA; Portland, OR; San Diego, CA; and Virginia Beach and Norfolk, VA. Multivariable generalized hierarchical linear modeling was used to examine how sexual behavior stigmas (stigma from family, anticipated healthcare stigma, general social stigma) measured at the individual and site levels and state HIV criminalization legislation (no, HIV-specific, or sentence-enhancement laws) were associated with past-year HIV testing behaviors across sites (n = 3,278). RESULTS: The majority of MSM across sites were tested for HIV in the past two years (n = 2,909, 95.4%) with the average number of times tested ranging from 1.79 (SD = 3.11) in Portland, OR to 4.95 (SD = 4.35) in Los Angeles, CA. In unadjusted models, there was a significant positive relationship between stigma from family and being tested for HIV in the past two years. Site-level HIV-specific criminalization laws were associated with an approximate 5% reduction in the prevalence of receiving any HIV test in the past two years after individual level stigma and sociodemographic covariate adjustments (PR = 0.94, 95% CI, 0.90-0.99). CONCLUSIONS: Structural barriers faced by MSM persist and ending the HIV epidemic in the US requires a supportive legal environment to ensure effective engagement in HIV services among MSM. Home-based solutions, such as self-testing, used to deliver HIV testing may be particularly important in punitive settings while legal change is advocated for on the community and state levels.

The Impact of the SARS-CoV-2 Pandemic on Human Immunodeficiency Virus and Bacterial Sexually Transmitted Infection Testing and Diagnosis in Oregon.

ABSTRACT: Human immunodeficiency virus, Neisseria gonorrhoeae/Chlamydia trachomatis, and syphilis testing decreased with the implementation of mitigation measures for SARS-CoV-2 and did not return to 2019 levels by September 2020. However, primary and secondary syphilis diagnoses increased during mitigation measures. Sexual health services are essential during the SARS-CoV-2 pandemic.

Multifactorial Correlates of Incident Bacterial Sexually Transmitted Infections Among Black Men Who Have Sex With Men Recruited in 6 US Cities (HIV Prevention Trials Network 061).

BACKGROUND: Black men who have sex with men are at a disproportionate risk for sexually transmitted infections (STI). Understanding the drivers of those disparities can lead to culturally tailored interventions. We aimed to characterize the incidence and correlates of STI among Black individuals from HIV Prevention Trials Network 061, a multicity cohort study conducted from 2009 to 2011 in the United States. METHODS: We used Cox proportional hazards regression to estimate adjusted hazard ratios (aHRs) accounting for within-participant correlation over multiple follow-up visits (enrollment, 6 and 12 months). We examined correlates of incident rectal and urethral STI as well as incident syphilis. RESULTS: Among 1522 individuals, the incidences of urethral and rectal Neisseria gonorrhoeae infection were 1.0 (95% confidence interval, 0.6-1.8) and 4.6 (95% CI, 3.5-6.3) cases per 100 person-years, respectively. The incidences of urethral and rectal Chlamydia trachomatis infection were 2.5 (95% CI, 1.7-3.6) and 2.5 (95% CI, 1.7-3.7) cases per 100 person-years, respectively. The incidence of syphilis was 3.6 (95% CI, 2.7-4.9) cases per 100 person-years. Younger age was associated with increased odds of incident urethral (aHR, 5.1; 95% CI, 2.3-11.1) and rectal (aHR, 2.6; 95% CI, 1.6-4.3) STI. Diagnosis of a rectal STI at baseline (aHR, 2.3; 95% CI, 1.1-4.0) and use of saliva as lubricant (aHR, 1.7; 95% CI, 1.1-2.8) were associated with incident rectal STI. Diagnosis of syphilis at baseline was associated with incident syphilis during follow-up (aHR, 5.6; 95% CI, 2.5-12.2). CONCLUSIONS: Younger participants had the highest STI incidence. Use of saliva as lubricant may be a driver of rectal infection, which deserves further study.

Rapid Uptake of Home-Based HIV Self-testing During Social Distancing for SARS-CoV2 Infection in Oregon.

We implemented a pilot home HIV self-testing program one week after a stay-home order for SARS-CoV2 was enacted in Oregon. We advertised the program on a geospatial networking app and community partner websites targeting men who have sex with men; nine percent of web visits resulted in an order. Over 70% of the kits initially allotted to the program were ordered in the first 24 h of launch. One-third of participants had never tested for HIV. We found enthusiasm for discreet, free, home-based testing and uncovered an unmet need for HIV testing as clinical and outreach programs shuttered in Oregon.

Pre-exposure Prophylaxis Awareness and Use Among Cisgender Men Who Have Sex With Men and Use Methamphetamine in 3 Western US Cities.

BACKGROUND: In the United States, cisgender men who have sex with men (MSM) who use methamphetamine are at substantial risk for HIV and can benefit from pre-exposure prophylaxis (PrEP). METHODS: We used data from the National HIV Behavioral Surveillance 2017 survey from Seattle, WA; Portland, OR; and Denver, CO, to estimate PrEP awareness and use in the past 12 months among MSM who use methamphetamine. We then compared these estimates with participants who do not use methamphetamine but meet other criteria for PrEP use (i.e., condomless anal sex or a bacterial sexually transmitted infection). We explored reasons for not using PrEP and challenges using PrEP. RESULTS: Of the 1602 MSM who participated in the 2017 National HIV Behavioral Surveillance survey in Seattle, WA; Portland, OR; and Denver, CO, 881 met the inclusion criteria for this study, of whom 88 (10%) reported methamphetamine use in the past 12 months. Most (95%) participants had heard of PrEP, and 35% had used it in the past 12 months. Pre-exposure prophylaxis awareness was lower among MSM who used methamphetamine (P = 0.01), but use was not different (P = 0.26). Among those who had not used PrEP, the most common reason for not using it was not thinking one's HIV risk was high enough (51%). Men who have sex with men who used methamphetamine were more likely to report that they were not sure PrEP would prevent them from getting HIV (38% vs. 19%, P = 0.002). CONCLUSIONS: These results highlight the need for continued efforts to educate and promote PrEP uptake among MSM, particularly those who use methamphetamine.

Prevalence and correlates of transactional sex among women of low socioeconomic status in Portland, OR.

BACKGROUND: Women who report transactional sex are at increased risk for HIV and other sexually transmitted infections (STIs). However, in the United States, social, behavioral, and trauma-related vulnerabilities associated with transactional sex are understudied and data on access to biomedical HIV prevention among women who report transactional sex are limited. METHODS: In 2016, we conducted a population-based, cross-sectional survey of women of low socioeconomic status recruited via respondent-driven sampling in Portland, Oregon. We calculated the prevalence and, assessed the correlates of, transactional sex using generalized linear models accounting for sampling design. We also compared health outcomes, HIV screening, and knowledge and uptake of HIV pre-exposure prophylaxis (PrEP) between women who did and did not report transactional sex. RESULTS: Of 334 women, 13.6% reported transactional sex (95% confidence interval [CI]: 6.8, 20.5%). Women who reported transactional sex were older, more likely to identify as black, to identify as lesbian or bisexual, to experience childhood trauma and recent sexual violence, and to have been homeless. Six percent (95% CI: 1.8, 10.5%) of women with no adverse childhood experiences (ACEs) reported transactional sex compared to 23.8% (95% CI: 13.0, 34.6%) of women who reported eleven ACEs (P <  0.001). Transactional sex was strongly associated with combination methamphetamine and opiate use as well as condomless sex. Women who reported transactional sex were more likely to report being diagnosed with a bacterial STI and hepatitis C; however, HIV screening and pre-exposure prophylaxis knowledge and use were low. CONCLUSIONS: In a sample of women of low socioeconomic status in Portland, Oregon, transactional sex was characterized by marginalized identities, homelessness, childhood trauma, sexual violence, substance use, and sexual vulnerability to HIV/STI. Multi-level interventions that address these social, behavioral, and trauma-related factors and increase access to biomedical HIV prevention are critical to the sexual health of women who engage in transactional sex.

Increasing Syphilis Detection Among Patients Assigned Male at Birth Screened at a Boston Community Health Center Specializing in Sexual and Gender Minority Health, 2005-2015.

BACKGROUND: United States syphilis rates have increased to levels last seen in the 1990s. We examined syphilis epidemiology of patients attending a Boston community health center specializing in sexual and gender minority health. METHODS: We performed a retrospective cohort study of all patients assigned male at birth screened with rapid plasma reagin from 2005 through 2015. We developed an algorithm to identify new infections and used repeat cross-sectional analysis to assess temporal trends in syphilis diagnoses. We also performed longitudinal analysis to calculate syphilis incidence using a Cox proportional hazards model that accounts for multiple infections over time. RESULTS: Eighteen thousand two hundred eighty-two patients had a total of 57,080 rapid plasma reagins, 1170 (2.0%) tests met criteria for syphilis. Adjusted syphilis diagnoses increased from 1.2% to 1.9%, recurrent syphilis diagnoses increased from 0.04% to 0.3% during the study period. Black and Hispanic/Latinx patients, patients aged 35 to 44 years, gay/bisexual patients, cisgender men, and human immunodeficiency virus (HIV)-infected patients and those who became HIV-infected during the study period were more likely to test positive for syphilitic infection in repeat cross-sectional analysis. Among 6199 patients screened more than 1 time over 21,745 person-years, there were 661 new syphilis cases (3.0% annual incidence; 95% confidence interval [CI], 2.8% to 3.2%). Compared with those aged 14 to 24 years, patients 45 years or older were less likely to experience syphilis. New HIV infection was associated with increased risk of incident syphilis (adjusted hazard ratio, 2.87; 95% CI, 1.61-5.13). Virally suppressed HIV-infected patients were less likely to experience incident syphilis (adjusted hazard ratio, 0.69; 95% CI, 0.55-0.87). CONCLUSIONS: The high incidence of syphilis among patients assigned male at birth disproportionately affected young patients, black and Hispanic/Latinx patients, gay/bisexual patients, cisgender men, and those with new or chronic HIV infection. Syphilitic reinfection rates increased over time.

Factors Associated With Increased Syphilis Screening Among People Living With Human Immunodeficiency Virus.

BACKGROUND: Antiretroviral therapy effectively reduces the risk of human immunodeficiency virus transmission, but in the context of undetectable equals untransmittable and decreased condom use, rates of syphilis are increasing. In Oregon, syphilis has risen over 20-fold in the past decade, from less than 30 to approximately 600 cases annually during 2016 and 2017. Although many cases are among people living with human immunodeficiency virus infection (PLWH), screening for syphilis among PLWH is often lacking. The objective of this study was to estimate the prevalence of past-year syphilis testing among PLWH in Oregon to identify facility-level and individual-level factors associated with testing. METHODS: We examined 2015 to 2016 Medical Monitoring Project interview and medical records data in Oregon and conducted supplemental interviews with participants' medical providers. We used generalized mixed effects models to identify factors associated with syphilis screening. RESULTS: Sixty-nine percent of Medical Monitoring Project participants had past-year syphilis screening. Patients receiving care from facilities with written sexually transmitted infection screening policies were far more likely to be screened than those receiving care from facilities without written policies (94% vs. 43%, P < 0.001). Participants who identified as male were more likely to have been tested, even after adjusting for facility-level characteristics. Clustering within facility accounted for about 15% of the unexplained variability in the adjusted mixed effects models. CONCLUSIONS: Written sexually transmitted infection screening policies at medical facilities appear to be an important tool for ensuring syphilis screening occurs as recommended to prevent the continued rise in syphilis.

Structural-Level Racial-, Sexual Orientation-, and HIV-Related Discrimination and Subsequent Criminal Justice Involvement Among Young, Black, Men Who Have Sex With Men in North Carolina.

Multiple aspects of Black young men who have sex with men's (YMSM) identities cause them to be differentially targeted for arrest and incarceration. However, limited research has explored structural drivers of Black YMSM' criminal justice involvement, particularly co-occurring forms of discrimination. This article examines the temporal relationship between perceived racial discrimination, perceived sexual orientation discrimination, and community-level HIV discrimination and criminal justice involvement among Black YMSM in North Carolina. The study followed 465 Black YMSM from November 2013 to October 2016 who were recruited for a randomized controlled trial to test an internet-based intervention for Black YMSM living with, and at risk for HIV; participants completed online surveys at baseline, 3, 6, and 12 months. Logistic regression was used to explore the relationship between the three predictors at baseline (i.e., perceived racism and sexual orientation discrimination and community-level HIV discrimination) and criminal justice involvement at follow-up. All three predictor variables were significantly associated with subsequent criminal justice involvement in separate regression models that adjusted for other covariates: HIV discrimination (aOR = 1.06 [1.01-1.11]), perceived sexual orientation discrimination (aOR = 1.12 [1.00-1.27]), and perceived racism (aOR = 1.26 [1.12-1.42]). Perceived racism remained significant in the model with all three predictors (aOR = 1.29 [1.07-1.55]). Racism did not modify the relationship between HIV discrimination and perceived sexual orientation discrimination and criminal justice involvement. This study expands existing research by exploring racism as a structural driver of criminal justice involvement; we subsequently examined whether racism modified the effect of the two other predictors. It also contributes to research on co-occurring discrimination by examining their impact on an underrepresented population.

Anatomic Site-Specific Gonorrhea and Chlamydia Testing and Incidence Among People With HIV Engaged in Care at 4 US Clinical Centers, 2014-2018.

Background: The incidence of Neisseria gonorrhoeae (GC) and Chlamydia trachomatis (CT) is increasing in the United States; however, there are limited data on anatomic site-specific GC/CT among people with HIV (PWH). Methods: We reviewed records of all PWH in care between January 1, 2014, and November 16, 2018, at 4 sites in the CFAR Network of Integrated Clinical Systems Cohort (CNICS; n = 8455). We calculated anatomic site-specific GC/CT testing and incidence rates and used Cox proportional hazards models modified for recurrent events to examine sociodemographic and clinical predictors of GC/CT testing and incidence at urogenital, rectal, and pharyngeal sites. We also calculated site-specific number needed to test (NNT) to detect a positive GC/CT test. Results: Of 8455 PWH, 2460 (29.1%) had at least yearly GC/CT testing at any anatomic site. The rates of urogenital, rectal, and pharyngeal GC were 1.7 (95% CI, 1.6-1.9), 3.2 (95% CI, 3.0-3.5), and 2.7 (95% CI, 2.5-2.9) infections per 100 person-years, respectively. The rates of urogenital, rectal, and pharyngeal CT were 1.9 (95% CI, 1.7-2.1), 4.3 (95% CI, 4.0-4.5), and 0.9 (95% CI, 0.8-1.0) infections per 100 person-years, respectively. PWH 16-39 years old experienced greater GC/CT rates at all anatomic sites, while men who have sex with men experienced greater rates of extragenital infections. NNTs for urogenital, rectal, and pharyngeal GC/CT were 20 (95% CI, 19-21), 5 (95% CI, 5-5), and 9 (95% CI, 8-9), respectively. Conclusions: Many PWH are not tested annually for GC/CT, and rates of GC/CT infection, particularly rates of extragenital infections, are high. We identified groups of PWH who may benefit from increased site-specific GC/CT testing.

Direct and Indirect Effects of a Project ECHO Longitudinal Clinical Tele-Mentoring Program on Viral Suppression for Persons With HIV: A Population-Based Analysis.

BACKGROUND: Project Extension for Community Health Outcomes (ECHO) aims to connect community providers to academic specialists, deliver longitudinal clinical mentorship and case consultations, plus encourage dissemination of knowledge and resources. The impact on outcomes for persons with HIV (PWH) is uncertain. SETTING: PWH in Washington and Oregon outside of the Seattle and Portland metro areas, January 2011 to March 2018. METHODS: Using viral load (VL) surveillance data, we assessed difference in the percentage of PWH who were virally suppressed among PWH whose providers participated versus did not participate in Project ECHO. Analyses included multiple mixed-effects regression models, adjusting for time and for patient, provider, and clinic characteristics. RESULTS: Based on 65,623 VL results, Project ECHO participation was associated with an increase in the percentage of patients with VL suppression (13.7 percentage points greater; P < 0.0001), although the effect varied by estimated provider PWH patient volume. The difference was 14.7 percentage points ( P < 0.0001) among patients of providers who order <20 VL's/quarter and 2.3 and -0.6 percentage points among patients of providers who order 20-40 or >40 VL's/quarter, respectively ( P > 0.5). The magnitude of difference in VL suppression was associated with the number of sessions attended. Among patients of lower-volume providers who did not participate, VL suppression was 6.2 percentage points higher if providers worked in a clinic where another provider did participate ( P < 0.0001). CONCLUSION: Project ECHO is associated with improvement in VL suppression for PWH whose providers participate or work in the same clinic system as a provider who participates, primarily because of benefits for patients of lower-volume providers.

Stable sexual risk behavior in a rapidly changing risk environment: findings from population-based surveys of men who have sex with men in Seattle, Washington, 2003-2006.

We assessed trends in behavioral risk for HIV infection among men who have sex with men (MSM). Seattle MSM participated in random digit dial telephone surveys in 2003 (n = 400) and 2006 (n = 400). Fourteen percent in 2003 and 9% in 2006 reported unprotected anal intercourse with a partner of different or unknown HIV status (non-concordant UAI; odds ratio [OR] = 0.7; 95% confidence interval [CI]: 0.5, 1.2). Compared to participants in 2003, participants in 2006 met a greater proportion of their anal sex partners through the Internet (OR = 2.0; 95% CI: 1.2, 3.1). Although the proportion of anal sex partnerships formed online increased between 2003 and 2006, Internet partnerships were not more risky than those initiated elsewhere. While the emergence of the Internet as a venue through which men meet partners demonstrates that sexual risk among MSM remains highly dynamic, our findings suggest that sexual risk behavior among MSM is currently stable.

Social Determinants of Health and Care Outcomes Among People With HIV in the United States.

BACKGROUND: Fewer than 70% of people with HIV (PWH) in the United States have achieved durable viral suppression. To end the HIV epidemic in the United States, clinicians, researchers, and public health practitioners must devise ways to remove barriers to effective HIV treatment. To identify PWH who experience challenges to accessing health care, we created a simple assessment of social determinants of health (SDOH) among PWH and examined the impact of cumulative social and economic disadvantage on key HIV care outcomes. METHODS: We used data from the 2015-2019 Medical Monitoring Project, a yearly cross-sectional survey of PWH in the United States (n = 15 964). We created a 10-item index of SDOH and assessed differences in HIV care outcomes of missed medical appointments, medication adherence, and durable viral suppression by SDOH using this index using prevalence ratios with predicted marginal means. RESULTS: Eighty-three percent of PWH reported at least 1 SDOH indicator. Compared with PWH who experienced none of the SDOH indicators, people who experienced 1, 2, 3, and 4 or more SDOH indicators were 1.6, 2.1, 2.6, and 3.6 as likely to miss a medical appointment in the prior year; 11%, 17%, 20%, and 31% less likely to report excellent adherence in the prior 30 days; and 2%, 4%, 10%, and 20% less likely to achieve durable viral suppression in the prior year, respectively. CONCLUSIONS: Among PWH, cumulative exposure to social and economic disadvantage impacts care outcomes in a dose-dependent fashion. A simple index may identify PWH experiencing barriers to HIV care, adherence, and durable viral suppression in need of critical supportive services.
