PURPOSE/OBJECTIVE:To improve testing coverage, it is imperative to determine adolescent girls and young women (AGYW) preferences about HIV testing modality and where they prefer receiving services. METHODS:Participants were enrolled between May 2017 and April 2018 from three sites in Homa Bay County, Nyanza region, western Kenya. We explored two recruitment approaches (home-based vs. mobile-event based) and three HIV testing options (oral self-test, staff-administered, or referral to health facility). Exact logistic regression compared yield of newly diagnosed HIV and high-risk HIV-negatives from the recruitment and testing option strategies. RESULTS:A total of 1,198 participants were enrolled, 1,046 (87.3%) at home and 152 (12.7%) at mobile events. Most participants (928, 77.5%) chose staff-aided testing either at home or at a mobile event; 268 (22.4%) chose self-testing; and only 2 (.2%) chose facility referral. Prevalence of newly diagnosed HIV-positives was 2.7% (32/1,198) and 36.8% (429/1,166) of HIV-negative AGYW were identified as high risk. We identified more newly diagnosed HIV infection among AGYW recruited at mobile events than at home (OR = 3.11; 95% CI: 1.33-6.74; p = .02). High-risk status was related to neither recruitment strategy nor testing modality. Older age was associated with increased odds of selecting an oral self-test (OR = 1.85; 95% CI: 1.06-3.22). CONCLUSIONS:More than one-third of AGYW were at elevated risk of HIV infection, and those unaware of their HIV infection were more likely to be identified at a mobile outreach. Though self-testing was not the dominant preferred strategy, self-tests were performed accurately and with high confidence. These findings can help inform efficient identification of undiagnosed HIV infection and high risk for seroconversion among AGYW in similar settings.

Black men who have sex with men (BMSM) have disproportionate HIV/STI acquisition risk. Incarceration may increase exposure to violence and exacerbate psychosocial vulnerabilities, including internalized homophobia, which are associated with HIV/STI acquisition risk. Using data from HIV Prevention Trials Network 061 (N = 1553), we estimated adjusted prevalence ratios (APR) and 95% confidence intervals (CIs) for associations between lifetime burden of incarceration and HIV/STI risk outcomes. We measured associations between incarceration and HIV/STI risk outcomes with hypothesized mediators of recent violence victimization and internalized homophobia. Compared to those never incarcerated, those with 3-9 or ≥ 10 incarcerations had approximately 10% higher prevalence of multiple partnerships. Incarceration burden was associated with selling sex (1-2 incarcerations: APR: 1.52, 95% CI 1.14-2.03; 3-9: APR: 1.77, 95% CI 1.35-2.33; ≥ 10: APR: 1.85, 95% CI 1.37-2.51) and buying sex (≥ 10 incarcerations APR: 1.80, 95% CI 1.18-2.75). Compared to never incarcerated, 1-2 incarcerations appeared to be associated with current chlamydia (APR: 1.47, 95% CI 0.98-2.20) and 3-9 incarcerations appeared to be associated with current syphilis (APR: 1.46, 95% CI 0.92-2.30). Incarceration was independently associated with violence, which in turn was a correlate of transactional sex. Longitudinal research is warranted to clarify the role of incarceration in violence and HIV/STI risk in this population.

Research Objective: Studies have found that race/ethnicity concordance between patients and providers improves medication adherence among patients with hypertension and single CVD outcomes (eg, blood pressure control). Our objective was to examine the association of patient-physician race/ethnicity concordance on adherence to the Million Hearts "ABCS" CVD guidelines: (A) aspirin when indicated, (B) blood pressure control, (C) cholesterol management, and (S) smoking screening and cessation. To the best of our knowledge, this is the first study to examine the impact of race/ ethnicity concordance on guideline adherence to multiple CVD outcome measures.
Study Design: This study was part of HealthyHearts NYC, a stepped-wedge cluster randomized controlled trial funded through AHRQ's EvidenceNOW initiative to test the effectiveness of practice facilitation on helping primary care practices adhere to CVD guidelines. The main outcomes were the Million Hearts' ABCS measures. Two additional measures were created: (a) proportion of patients who use tobacco who received a cessation intervention (smokers counseled) and (b) a composite measure that assessed the proportion of patients meeting treatment targets for A, B, and C (ABC composite). Practice-level outcome data were extracted for thirteen quarters from practices' electronic health record (EHR) systems, encompassing the control, intervention, and follow-up periods of the intervention. Patient-physician race/ethnicity concordance was calculated using patient race/ethnicity data extracted from the practices' EHR and physician race/ethnicity data collected via a Provider Survey. The concordance measure was calculated as the proportion of patients with the same race/ethnicity as the physician, for example, if practice is led by an Asian physician, and patients are 33% non-Hispanic white, 5% non-Hispanic black, 5% Hispanic, and 57% Asian, the concordance is 0.57. Population Studied: 211 small primary care practices in NYC. Principal Findings: 57.7% of Hispanic, 53.6% of black, 73.6% of Asian, 74.2% of non-Hispanic white, and 24.1% of Hawaiian/Pacific Islander patients had the same race/ethnicity as their physicians. 44.7% of physicians had the same race/ethnicity as at least 70% of their patients. Patient-physician race/ethnicity concordance was associated with adherence to four of our six outcome measures: aspirin (IRR = 1.08, 95% CI: 1.03-1.14, P < .001); blood pressure (IRR = 1.09, 95% CI: 1.07-1.12, P < .001); smoking screening and cessation (IRR = 1.06, 95% CI: 1.04-1.08, P < .001); and ABC composite (IRR = 1.42, 95% CI: 1.33-1.52, P < 0.001). We did not find an association for race/ethnicity concordance with Cholesterol and Smokers Counseled.
Conclusion(s): Increasing opportunities for patient-physician race/ ethnicity concordance may improve adherence to CVD guidelines. The largest improvement was observed in the ABC Composite measure, suggesting that patient-physician race/ethnicity concordance is particularly important for managing medically complex patients who have multiple chronic diseases. Implications for Policy or Practice: Health policy should fund programs that support the recruitment and retention of a wide diversity of students and faculty to increase the level of concordance in patient-clinician encounters. Policy makers may also want to consider legislation to help support or protect small practices that predominantly serve communities of color, where a large proportion of the physicians may be racially/ ethnically concordant with the patient population. Medical education programs should incorporate patient-physician communication training to minimize gaps potentially created by race/ethnicity discordance

BACKGROUND AND AIMS/OBJECTIVE:While substance use can lead to incarceration, the disruptive effects of incarceration may lead to, or increase psychosocial vulnerability and substance use. Using causal inference methods, we measured longitudinal associations between incarceration and post-release substance use among Black men who have sex with men (BMSM), populations facing disproportionate risk of incarceration and substance use. METHODS:Using data from the HIV Prevention Trials Network (HPTN 061) study (N = 1553) we estimated associations between past 6-month incarceration and binge drinking, marijuana use, and stimulant use post release (at 12-month follow-up visit). Adjusted models used inverse probability weighting (IPW) to control for baseline (pre-incarceration) substance use and additional risk factors. RESULTS:There were 1133 participants present at the twelve-month follow-up visit. Participants were predominately non-Hispanic Blacks and unemployed. At baseline, 60.1 % reported a lifetime history of incarceration, 22.9 % were HIV positive and 13.7 % had a history of an STI infection. A total of 43 % reported a history of depression. In adjusted analyses with IPW, recent incarceration was associated with crack-cocaine (adjusted odds ratio (AOR): 1.53, 95 % confidence interval (CI): 1.03, 2.23) and methamphetamine use (AOR: 1.52, 95 % CI: 0.94-2.45). Controlling for pre-incarceration binge drinking, incarceration was associated with post-release binge drinking (AOR: 1.47, 95 % CI: 1.05, 2.04); in fully adjusted models the AOR was 1.14 (95 % CI: 0.81, 1.62). Incarceration was not associated with marijuana use. CONCLUSION/CONCLUSIONS:Findings underscore the need to provide substance use treatment in custody and post-release, and to consider alternatives to incarceration for substance using populations.

Background/UNASSIGNED:Ecstasy (3,4-methylenedioxymethamphetamine [MDMA]), commonly referred to as Molly in the US, is commonly adulterated with drugs potentially more dangerous than MDMA. Synthetic cathinones ("bath salts") are common adulterants, and use of these compounds tends to be stigmatized. We investigated whether presenting information on the extent of ecstasy being adulterated with "bath salts" affects intentions to use. Methods/UNASSIGNED:A total of 1,025 adults entering electronic dance music parties were surveyed in 2018. Using an experimental posttest-only design with random assignment, half were randomly assigned to view a published Vice headline about ecstasy/Molly commonly being adulterated with "bath salts." Results/UNASSIGNED:= .030) of past-year ecstasy users' intention to test their ecstasy for adulterants. Conclusions/UNASSIGNED:Knowledge that ecstasy is commonly adulterated may help reduce the risk for future use among non-recent users and increase the willingness of users to test their ecstasy. This information can be used to target those at risk for ecstasy/Molly use.

BACKGROUND:Hepatitis C virus (HCV) remains endemic among people who use drugs (PWUD). Measures of HCV community viral load (CVL) and HCV care continuum outcomes may be valuable for ascertaining unmet treatment need and for HCV surveillance and control. METHODS:Data from patients in an opioid treatment program during 2013-2016 were used to (1) identify proportions of antibody and viral load (VL) tested, linked-to-care, and treated, in 2013-2014 and 2015-2016, and pre- and postimplementation of qualitative reflex VL testing; (2) calculate engaged-in-care HCV CVL and "documented" and "estimated" unmet treatment need; and (3) examine factors associated with linkage-to-HCV-care. RESULTS:Among 11 267 patients, proportions of HCV antibody tested (52.5% in 2013-2014 vs 73.3% in 2015-2016), linked-to-HCV-care (15.7% vs 51.8%), and treated (12.0% vs 44.7%) all increased significantly. Hispanic ethnicity was associated with less linkage-to-care, and Manhattan residence was associated with improved linkage-to-care. The overall engaged-in-care HCV CVL was 4 351 079 copies/mL (standard deviation = 7 149 888); local HCV CVLs varied by subgroup and geography. Documented and estimated unmet treatment need decreased but remained high. CONCLUSIONS:After qualitative reflex VL testing was implemented, care continuum outcomes improved, but gaps remained. High rates of unmet treatment need suggest that control of the HCV epidemic among PWUD will require expansion of HCV treatment coverage.

BACKGROUND:Hepatitis C virus (HCV) incidence has increased in the worsening opioid epidemic. We examined the HCV preventive efficacy of medication-assisted treatment (MAT), and geographic variation in HCV community viral load (CVL) and its association with HCV incidence. METHODS:HCV incidence was directly measured in an open cohort of patients in a MAT program in New York City between 1 January 2013 and 31 December 2016. Area-level HCV CVL was calculated. Associations of individual-level factors, and of HCV CVL, with HCV incidence were examined in separate analyses. RESULTS:Among 8352 patients, HCV prevalence was 48.7%. Among 2535 patients seronegative at first antibody test, HCV incidence was 2.25/100 person-years of observation (PYO). Incidence was 6.70/100 PYO among those reporting main drug use by injection. Female gender, drug injection, and lower MAT retention were significantly associated with higher incidence rate ratios. Female gender, drug injection, and methadone doses <60 mg were independently associated with shorter time to HCV seroconversion. HCV CVLs varied significantly by geographic area. CONCLUSIONS:HCV incidence was higher among those with lower MAT retention and was lower among those receiving higher methadone doses, suggesting the need to ensure high MAT retention, adequate doses, and increased HCV prevention and treatment engagement. HCV CVLs vary geographically and merit further study as predictors of HCV incidence.
