Medical distrust is a potent barrier to participation in HIV care and medication use among African American/Black and Latino (AABL) persons living with HIV (PLWH). However, little is known about sociodemographic and risk factors associated with distrust. We recruited adult AABL PLWH from low socio-economic status backgrounds with insufficient engagement in HIV care (N = 512). Participants completed structured assessments on three types of distrust (of health care providers, health care systems, and counter-narratives), HIV history, and mental health. We used a type of machine learning called random forest to explore predictors of trust. On average, participants were 47 years old (SD = 11 years), diagnosed with HIV 18 years prior (SD = 9 years), and mainly male (64%) and African American/Black (69%). Depression and age were the most important predictors of trust. Among those with elevated depressive symptoms, younger participants had less trust than older, while among those without depression, trust was greater across all ages. The present study adds nuance to the literature on medical distrust among AABL PLWH and identifies junctures where interventions to build trust are needed most.

OBJECTIVE:Guided by a resilience framework, this study examines the accumulation of risk and protective factors, as well as the potential buffering effects of protective factors on mental distress among female military spouses. BACKGROUND:Most research with this population has focused on individual risk factors affecting military spouses. Less frequently have the effects of cumulative risk, risk factors not specifically associated with military service, or protective factors been examined, though there is evidence for their importance. METHOD/METHODS:This study used secondary survey data from 334 female Army spouses collected in 2012 as part of the Land Combat Study 2. Cumulative risk and protective factor scores as well as scores within risk (intrapersonal, family, and military-specific) and protective (individual and environmental) factor domains were calculated. Four structural equation models were run to examine main and interaction effects on mental distress, a latent variable representing depression, anxiety, and trauma symptoms. RESULTS:In cumulative risk and protective factor models, cumulative risk was directly, positively associated with mental distress. This relationship was moderated by cumulative protection. In domain-specific models, only family risk was directly associated with mental distress. This relationship was moderated by environmental protective factors. CONCLUSION/CONCLUSIONS:Findings indicate mental distress among military spouses is associated with exposure to cumulative risk and attenuated by the presence of certain domains of protective factors. Family risk factors including marital distress and work-family conflict may be particularly pernicious stressors, but informal and structural supports may be important targets for prevention and intervention efforts.

Few studies have assessed the fidelity of practice facilitation (PF) as an implementation strategy, and none have used an a priori definition or conceptual framework of fidelity to guide fidelity assessment. The authors adapted the Conceptual Framework for Implementation Fidelity to guide fidelity assessment in HealthyHearts NYC, an intervention that used PF to improve adoption of cardiovascular disease evidence-based guidelines in primary care practices. Data from a web-based tracking system of 257 practices measured fidelity using 4 categories: frequency, duration, content, and coverage. Almost all (94.2%) practices received at least the required 13 PF visits. Facilitators spent on average 26.3 hours at each site. Most practices (95.7%) completed all Task List items, and 71.2% were educated on all Chronic Care Model strategies. The majority (65.8%) received full coverage. This study provides a model that practice managers and implementers can use to evaluate fidelity of PF, and potentially other implementation strategies.

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.

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.

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:Maintaining adherence to antiretroviral therapy is a significant challenge for HIV-infected racial and ethnic minority adolescents and young adults (youth). Given the consequences of suboptimal antiretroviral therapy adherence, there is a pressing need for an expanded understanding of adherence behavior in this cohort. OBJECTIVES/OBJECTIVE:As part of an exploratory sequential, mixed-methods study, we used qualitative inquiry to explore adherence information, motivation, and behavioral skills among HIV-infected racial and ethnic minority youth. Our secondary aim was to gain an understanding of the contextual factors surrounding adherence behavior. METHODS:The information-motivation-behavioral skills model was applied to identify the conceptual determinants of adherence behavior in our target population, along with attention to emergent themes. In-depth, individual, semistructured interviews including open-ended questions with probes were conducted with a convenience sample of HIV-infected racial and ethnic minority youth receiving antiretroviral therapy and with evidence of virologic failure (i.e., detectable HIV viral load). New participants were interviewed until information redundancy was reached. Qualitative interviews were digitally recorded, transcribed verbatim, and with directed content analysis to generate categories and broad themes. Coding was initially conceptually driven and shifted to a data-driven approach, allowing for the discovery of key contextual factors that influence adherence behavior in this population. Methodological rigor was ensured by member checks, an audit trail, thick descriptive data, and triangulation of data sources. RESULTS:Twenty racial and ethnic minority participants completed interviews. We found adherence information was understood in relation to HIV biomarkers; adherence motivation and behavioral skills were influenced by stigma and social context. We identified five primary themes regarding antiretroviral therapy self-management: (1) emerging adulthood with a chronic illness; (2) stigma and disclosure concerns; (3) support systems and support deficits; (4) mental and behavioral health risks and challenges; and (5) mode of HIV transmission and perceptions of power and control. DISCUSSION/CONCLUSIONS:Key constructs of the information-motivation- behavioral model were applicable to participating HIV-infected youth, yet did not fully explain the essence of adherence behavior. As such, we recommend expansion of current adherence models and frameworks to include known contextual factors associated with antiretroviral therapy self-management among HIV-infected racial and ethnic minority youth.

OBJECTIVES/OBJECTIVE:In this study, we evaluate the efficacy of Families Talking Together (FTT), a triadic intervention to reduce adolescent sexual risk behavior. METHODS:Adolescents aged 11 to 14 and their female caregivers were recruited from a pediatric clinic; 900 families were enrolled; 84 declined. Families were randomly assigned to FTT or 1 of 2 control conditions. The FTT triadic intervention consisted of a 45-minute face-to-face session for mothers, health care provider endorsement of intervention content, printed materials for families, and a booster call for mothers. The primary outcomes were ever having had vaginal intercourse, sexual debut within the past 12 months, and condom use at last sexual intercourse. Assessments occurred at baseline, 3 months post baseline, and 12 months post baseline. RESULTS:< .05). CONCLUSIONS:This research suggests that the FTT triadic intervention is efficacious in delaying sexual debut and reducing sexual risk behavior among adolescents.

INTRODUCTION/BACKGROUND:Practice facilitation is a promising practice transformation strategy, but further examination of its effectiveness in improving adoption of guidelines for multiple cardiovascular disease risk factors is needed. The objective of the study is to determine whether practice facilitation is effective in increasing the proportion of patients meeting the Million Hearts ABCS outcomes: (A) aspirin when indicated, (B) blood pressure control, (C) cholesterol management, and (S) smoking screening and cessation intervention. DESIGN/METHODS:The study used a stepped-wedge cluster RCT design with 4 intervention waves. Data were extracted for 13 quarters between January 1, 2015 and March 31, 2018, which encompassed the control, intervention, and follow-up periods for all waves, and analyzed in 2019. SETTING/PARTICIPANTS/METHODS:A total of 257 small independent primary care practices in New York City were randomized into 1 of 4 waves. INTERVENTION/METHODS:The intervention consisted of practice facilitators conducting at least 13 practice visits over 1 year, focused on capacity building and implementing system and workflow changes to meet cardiovascular disease care guidelines. MAIN OUTCOME MEASURES/METHODS:The main outcomes were the Million Hearts' ABCS measures. Two additional measures were created: (1) proportion of tobacco users who received a cessation intervention (smokers counseled) and (2) a composite measure that assessed the proportion of patients meeting treatment targets for A, B, and C (ABC composite). RESULTS:The S measure improved when comparing follow-up with the control period (incidence rate ratio=1.152, 95% CI=1.072, 1.238, p<0.001) and when comparing follow-up with intervention (incidence rate ratio=1.060, 95% CI=1.013, 1.109, p=0.007). Smokers counseled improved when comparing the intervention period with control (incidence rate ratio=1.121, 95% CI=1.037, 1.211, p=0.002). CONCLUSIONS:Increasing the impact of practice facilitation programs that target multiple risk factors may require a longer, more intense intervention and greater attention to external policy and practice context.
