Importance: Low-income minority children living in urban neighborhoods are at high risk for mental health problems and underachievement. ParentCorps, a family-centered, school-based intervention in prekindergarten, improves parenting and school readiness (ie, self-regulation and preacademic skills) in 2 randomized clinical trials. The longer-term effect on child mental health and academic performance is not known. Objective: To examine whether ParentCorps delivered as an enhancement to prekindergarten programs in high-poverty urban schools leads to fewer mental health problems and increased academic performance in the early elementary school years. Design, Setting, and Participants: This is a 3-year follow-up study of a cluster randomized clinical trial of ParentCorps in public schools with prekindergarten programs in New York City. Ten elementary schools serving a primarily low-income, black student population were randomized in 2005, and 4 consecutive cohorts of prekindergarten students were enrolled from September 12, 2005, through December 31, 2008. We report follow-up for the 3 cohorts enrolled after the initial year of implementation. Data analysis was performed from September 1, 2014, to December 31, 2015. Interventions: ParentCorps included professional development for prekindergarten and kindergarten teachers and a program for parents and prekindergarten students (13 two-hour group sessions delivered after school by teachers and mental health professionals). Main Outcomes and Measures: Annual teacher ratings of mental health problems and academic performance and standardized tests of academic achievement in kindergarten and second grade by testers masked to the intervention or control group randomization. Results: A total of 1050 children (4 years old; 518 boys [49.3%] and 532 girls [50.7%]) in 99 prekindergarten classrooms participated in the trial (88.1% of the prekindergarten population), with 792 students enrolled from 2006 to 2008. Most families in the follow-up study (421 [69.6%]) were low income; 680 (85.9%) identified as non-Latino black, 78 (9.8%) as Latino, and 34 (4.3%) as other. Relative to their peers in prekindergarten programs, children in ParentCorps-enhanced prekindergarten programs had lower levels of mental health problems (Cohen d = 0.44; 95% CI, 0.08-0.81) and higher teacher-rated academic performance (Cohen d = 0.21; 95% CI, 0.02-0.39) in second grade. Conclusions and Relevance: Intervention in prekindergarten led to better mental health and academic performance 3 years later. Family-centered early intervention has the potential to prevent problems and reduce disparities for low-income minority children. Trial Registration: clinicaltrials.gov Identifier: NCT01670227.

BACKGROUND: HealthyHearts NYC (HHNYC) will evaluate the effectiveness of practice facilitation as a quality improvement strategy for implementing the Million Hearts' ABCS treatment guidelines for reducing cardiovascular disease (CVD) among high-risk patients who receive care in primary care practices in New York City. ABCS refers to (A) aspirin in high-risk individuals; (B) blood pressure control; (C) cholesterol management; and (S) smoking cessation. The long-term goal is to create a robust infrastructure for implementing and disseminating evidence-based practice guidelines (EBPG) in primary care practices. METHODS/DESIGN: We are using a stepped-wedge cluster randomized controlled trial design to evaluate the implementation process and the impact of practice facilitation (PF) versus usual care on ABCS outcomes in 250 small primary care practices. Randomization is at the practice site level, all of which begin as part of the control condition. The intervention consists of one year of PF that includes a combination of one-on-one onsite visits and shared learning across practice sites. PFs will focus on helping sites implement evidence-based components of patient-centered medical home (PCMH) and the chronic care model (CCM), which include decision support, provider feedback, self-management tools and resources, and linkages to community-based services. DISCUSSION: We hypothesize that practice facilitation will result in superior clinical outcomes compared to usual care; that the effects of practice facilitation will be mediated by greater adoption of system changes in accord with PCMH and CCM; and that there will be increased adaptive reserve and change capacity. TRIAL REGISTRATION: NCT02646488.

BACKGROUND: Extended-release naltrexone (XR-NTX) is an injectable monthly sustained-release mu opioid receptor antagonist, which blocks the typical effects of heroin and other opioid agonists. Use of XR-NTX among opioid dependent persons leaving jails and prisons is increasing despite scant high-quality evidence regarding XR-NTX's effectiveness at re-entry. METHODS: This 24-week, open-label randomized controlled trial examines the effectiveness of XR-NTX as opioid relapse prevention at release from jail (N=85) compared to enhanced treatment as usual (ETAU, N=85). A third, non-randomized, quasi-experimental naturalistic arm of participants who have newly initiated a jail-to-community methadone treatment program (MTP, N=85) allows for comparisons to a methadone standard-of-care. RESULTS: We describe the rationale, design, and primary and secondary outcomes of the study. The primary outcome is an opioid relapse event; the primary contrast is a time-to-relapse comparison of XR-NTX and ETAU over a 24-week treatment phase. Secondary outcomes are rates of: (a) post-release opioid treatment participation, (b) opioid, alcohol, and cocaine use, (c) injection drug use and HIV sexual risk behaviors, (d) overdose (fatal and non-fatal) and all-cause mortality, and, (e) re-incarceration. CONCLUSIONS: XR-NTX is a potentially important, effective treatment and relapse prevention option for a large US population of persons with opioid use disorders leaving jails. This study will estimate XR-NTX's effectiveness relative to existing standards of care, including counseling-only treatment-as-usual and methadone maintenance.

Moving from a descriptive focus to a comprehensive analysis grounded in causal inference can be particularly daunting for disparities researchers. However, even a simple model supported by the theoretical underpinnings of causality gives researchers a better chance to make correct inferences about possible interventions that can benefit our most vulnerable populations. This commentary provides a brief description of how race/ethnicity and context relate to questions of causality, and uses a hypothetical scenario to explore how different researchers might analyze the data to estimate causal effects of interest. Perhaps although not entirely removed of bias, these causal estimates will move us a step closer to understanding how to intervene. (PsycINFO Database Record

BACKGROUND: Hospital care on weekends has been associated with delays in care, reduced quality, and poor clinical outcomes. OBJECTIVE: The purpose of this study was to evaluate the impact of a weekend hospital intervention on processes of care and clinical outcomes. The multifaceted intervention included expanded weekend diagnostic services, improved weekend discharge processes, and increased physician and care management services on weekends. DESIGN AND PATIENTS: This was an interrupted time series observational study of adult non-obstetric patients hospitalized at a single academic medical center between January 2011 and January 2014. The study included 18 months prior to and 19 months following the implementation of the intervention. Data were analyzed using segmented regression analysis with adjustment for confounders. MAIN MEASURES: The primary outcome was average length of stay. Secondary outcomes included percent of patients discharged on weekends, 30-day readmission rate, and in-hospital mortality rate. KEY RESULTS: The study included 57,163 hospitalizations. Following implementation of the intervention, average length of stay decreased by 13 % (95 % CI 10-15 %) and continued to decrease by 1 % (95 % CI 1-2 %) per month as compared to the underlying time trend. The proportion of weekend discharges increased by 12 % (95 % CI 2-22 %) at the time of the intervention and continued to increase by 2 % (95 % CI 1-3 %) per month thereafter. The intervention had no impact on readmissions or mortality. During the post-implementation period, the hospital was evacuated and closed for 2 months due to damage from Hurricane Sandy, and a new hospital-wide electronic health record was introduced. The contributions of these events to our findings are not known. We observed a lower inpatient census and found differences in patient characteristics, including higher rates of Medicaid insurance and comorbidities, in the post-Hurricane Sandy period as compared to the pre-Sandy period. CONCLUSIONS: The intervention was associated with a reduction in length of stay and an increase in weekend discharges. Our longitudinal study also illuminated the challenges of evaluating the effectiveness of a large-scale intervention in a real-world hospital setting.

BACKGROUND: Angiotensin converting enzyme inhibitors (ACEi) are widely used in the treatment of patients with hypertension. However, their efficacy in hypertensive blacks when compared with other antihypertensive agents is not well established. METHODS: Cohort study of patients using data from a clinical data warehouse of 434,646 patients from New York City's Health and Hospitals Corporation (HHC) from January 2004 - December 2009. Patients were divided into the following comparison groups: ACEi vs. Calcium Channel Blocker (CCB); ACEi vs. thiazide diuretics and ACEi vs. beta-blockers. Primary outcome was a composite of death, myocardial infarction or stroke. Secondary outcomes include the individual components and heart failure. RESULTS: In the propensity score matched ACEi vs. CCB comparison cohort (4,506 blacks in each group), ACEi was associated with higher risk of primary outcome (HR=1.45; 95% CI 1.19, 1.77; P=0.0003), myocardial infarction (HR=3.40; 95% CI 1.25, 9.22; P=0.02), stroke (HR=1.82; 95% CI 1.29, 2.57; P=0.001) and heart failure (HR=1.77; 95% CI 1.30, 2.42; P=0.0003) when compared with CCB. For the ACEi vs. thiazide diuretics comparison (5,337 blacks in each group), ACEi was associated with higher risk of primary outcome (HR=1.65; 95% CI 1.33, 2.05; P<0.0001), death (HR=1.35; 95% CI 1.03, 1.76; P=0.03), myocardial infarction (HR=4.00; 95% CI 1.34, 11.96; P=0.01), stroke (HR=1.97; 95% CI 1.34, 2.92; P=0.001) and heart failure (HR=3.00; 95% CI 1.99, 4.54; P<0.0001). For the ACEi vs. beta-blocker comparison, the outcomes between the groups were not significantly different. CONCLUSIONS: In a real-world cohort of hypertensive blacks, ACEi was associated with higher risk of cardiovascular events when compared with CCB or thiazide diuretics.
