Project description:Racial-ethnic disparities in acute stroke care can contribute to inequality in stroke outcomes. We examined race-ethnic disparities in acute stroke performance metrics in a voluntary stroke registry among Florida and Puerto Rico Get With the Guidelines-Stroke hospitals.Seventy-five sites in the Florida Puerto Rico Stroke Registry (66 Florida and 9 Puerto Rico) recorded 58 864 ischemic stroke cases (2010-2014). Logistic regression models examined racial-ethnic differences in acute stroke performance measures and defect-free care (intravenous tissue plasminogen activator treatment, in-hospital antithrombotic therapy, deep vein thrombosis prophylaxis, discharge antithrombotic therapy, appropriate anticoagulation therapy, statin use, smoking cessation counseling) and temporal trends. Among ischemic stroke cases, 63% were non-Hispanic white (NHW), 18% were non-Hispanic black (NHB), 14% were Hispanic living in Florida, and 6% were Hispanic living in Puerto Rico. NHW patients were the oldest, followed by Hispanics, and NHBs. Defect-free care was greatest among NHBs (81%), followed by NHWs (79%) and Florida Hispanics (79%), then Puerto Rico Hispanics (57%) (P<0.0001). Puerto Rico Hispanics were less likely than Florida whites to meet any stroke care performance metric other than anticoagulation. Defect-free care improved for all groups during 2010-2014, but the disparity in Puerto Rico persisted (2010: NHWs=63%, NHBs=65%, Florida Hispanics=59%, Puerto Rico Hispanics=31%; 2014: NHWs=93%, NHBs=94%, Florida Hispanics=94%, Puerto Rico Hispanics=63%).Racial-ethnic/geographic disparities were observed for acute stroke care performance metrics. Adoption of a quality improvement program improved stroke care from 2010 to 2014 in Puerto Rico and all Florida racial-ethnic groups. However, stroke care quality delivered in Puerto Rico is lower than in Florida. Sustained support of evidence-based acute stroke quality improvement programs is required to improve stroke care and minimize racial-ethnic disparities, particularly in resource-strained Puerto Rico.

Project description:Despite advances in HIV prevention and care, African Americans and Latino Americans remain at much higher risk of acquiring HIV, are more likely to be unaware of their HIV-positive status, are less likely to be linked to and retained in care, and are less likely to have suppressed viral load than are Whites. The first National HIV/AIDS Strategy (NHAS) has reducing these disparities as one of its three goals by encouraging the implementation of combination high-impact HIV intervention strategies. Federal agencies have expanded their collaborations in order to decrease HIV-related disparities through better implementation of data-driven decision making; integration and consolidation of the continuum of HIV care; and the reorganization of relationships among public health agencies, researchers, community-based organizations, and HIV advocates. Combination prevention, the integration of evidence-based and impactful behavioral, biomedical, and structural intervention strategies to reduce HIV incidence, provides the tools to address the HIV epidemic. Unfortunately, health disparities exist at every step along the HIV testing-to-care continuum. This provides an opportunity and a challenge to everyone involved in HIV prevention and care to understand and address health disparities as an integral part of ending the HIV epidemic in the United States. To further reduce health disparities, successful implementation of NHAS and combination prevention strategies will require multidisciplinary teams, including psychologists with diverse cultural backgrounds and experiences, to successfully engage groups at highest risk for HIV and those already infected with HIV. In order to utilize the comprehensive care continuum, psychologists and behavioral scientists have a role to play in reconceptualizing the continuum of care, conducting research to address health disparities, and creating community mobilization strategies.

Project description:Acute stroke education has focused on stroke symptom recognition. Lack of education about stroke preparedness and appropriate actions may prevent people from seeking immediate care. Few interventions have rigorously evaluated preparedness strategies in multiethnic community settings.The Acute Stroke Program of Interventions Addressing Racial and Ethnic Disparities (ASPIRE) project is a multilevel program using a community-engaged approach to stroke preparedness targeted to underserved black communities in the District of Columbia. This intervention aimed to decrease acute stroke presentation times and increase intravenous tissue-type plasminogen activator utilization for acute ischemic stroke.Phase 1 included (1) enhancement of focus of emergency medical services on acute stroke; (2) hospital collaborations to implement and enrich acute stroke protocols and transition District of Columbia hospitals toward primary stroke center certification; and (3) preintervention acute stroke patient data collection in all 7 acute care District of Columbia hospitals. A community advisory committee, focus groups, and surveys identified perceptions of barriers to emergency stroke care. Phase 2 included a pilot intervention and subsequent citywide intervention rollout. A total of 531 community interventions were conducted, reaching >10,256 participants; 3289 intervention evaluations were performed, and 19,000 preparedness bracelets and 14,000 stroke warning magnets were distributed. Phase 3 included an evaluation of emergency medical services and hospital processes for acute stroke care and a year-long postintervention acute stroke data collection period to assess changes in intravenous tissue-type plasminogen utilization.We report the methods, feasibility, and preintervention data collection efforts of the ASPIRE intervention.http://www.clinicaltrials.gov.

Project description:We examined racial/ethnic disparities in attention-deficit/hyperactivity disorder (ADHD) diagnosis and medication use and determined whether medication disparities were more likely due to underdiagnosis or undertreatment of African-American and Latino children, or overdiagnosis or overtreatment of white children.We used a population-based, multisite sample of 4297 children and parents surveyed over 3 waves (fifth, seventh, and 10th grades). Multivariate logistic regression examined disparities in parent-reported ADHD diagnosis and medication use in the following analyses: (1) using the total sample; (2) limited to children with an ADHD diagnosis or symptoms; and (3) limited to children without a diagnosis or symptoms.Across all waves, African-American and Latino children, compared with white children, had lower odds of having an ADHD diagnosis and of taking ADHD medication, controlling for sociodemographics, ADHD symptoms, and other potential comorbid mental health symptoms. Among children with an ADHD diagnosis or symptoms, African-American children had lower odds of medication use at fifth, seventh, and 10th grades, and Latino children had lower odds at fifth and 10th grades. Among children who had neither ADHD symptoms nor ADHD diagnosis by fifth grade (and thus would not likely meet ADHD diagnostic criteria at any age), medication use did not vary by race/ethnicity in adjusted analysis.Racial/ethnic disparities in parent-reported medication use for ADHD are robust, persisting from fifth grade to 10th grade. These findings suggest that disparities may be more likely related to underdiagnosis and undertreatment of African-American and Latino children as opposed to overdiagnosis or overtreatment of white children.

Project description:Disparities are differences in health outcomes among groups that originate from sources including historically experienced social injustice and broadly defined environmental exposures. Large health disparities exist, defined by many factors including race/ethnicity, sex, age, geography, and socioeconomic status. Studying disparities relies on measures of disease burden. Traditional measures, such as mortality, may be less applicable to neurological disorders, which often lead to substantial morbidity and lower quality of life, without necessarily causing death. Measures such as disability-adjusted life-years or healthy life expectancy may be more appropriate for assessing neurological disease and permit comparisons across diseases and communities. There are many approaches that can be used to study disparities. Analyses of population-based observational studies, patient registries, and administrative data all contribute to the understanding of disparities in humans. Animal and other experimental designs, including clinical trials, may be used to identify mechanisms and strategies to reduce disparities. All of these approaches have strengths and weaknesses. Ultimately, understanding and mitigating disparities will require use of all of these methods. Crucially, a focus on not only improving outcomes among all individuals in society but minimizing or eliminating differences between those with better outcomes and those who have historically been disadvantaged should drive the ongoing investigations into disparities. This review is focused on epidemiological approaches to examining the depth and determinants of racial-ethnic disparities in the United States related to stroke, stroke care, and stroke outcomes.

Project description:BackgroundColorectal cancer is curable if diagnosed early and treated properly. Black and Hispanic patients with colorectal cancer are more likely to experience treatment delays and/or receive lower standards of care. Socioeconomic deprivation may contribute to these disparities, but this has not been extensively quantified. We studied the interrelationship between patient race/ethnicity and neighborhood socioeconomic status (nSES) on receipt of timely appropriate treatment among patients with colorectal cancer in California.MethodsWhite, Black, and Hispanic patients (26,870) diagnosed with stage I-III colorectal cancer (2009-2013) in the California Cancer Registry were included. Logistic regression models were used to examine the association of race/ethnicity and nSES with three outcomes: undertreatment, >60-day treatment delay, and >90-day treatment delay. Joint effect models and mediation analysis were used to explore the interrelationships between race/ethnicity and nSES.ResultsHispanics and Blacks were at increased risk for undertreatment [Black OR = 1.39; 95% confidence interval (CI) = 1.23-1.57; Hispanic OR = 1.17; 95% CI = 1.08-1.27] and treatment delay (Black/60-day OR = 1.78; 95% CI = 1.57-2.02; Hispanic/60-day OR = 1.50; 95% CI = 1.38-1.64) compared with Whites. Of the total effect (OR = 1.15; 95% CI = 1.07-1.24) of non-white race on undertreatment, 45.71% was explained by nSES.ConclusionsLower nSES patients of any race were at substantially higher risk for undertreatment and treatment delay, and racial/ethnic disparities are reduced or eliminated among non-white patients living in the highest SES neighborhoods. Racial and ethnic disparities persisted after accounting for neighborhood socioeconomic status, and between the two, race/ethnicity explained a larger portion of the total effects.ImpactThis research improves our understanding of how socioeconomic deprivation contributes to racial/ethnic disparities in colorectal cancer.

Project description:Introduction Endovascular therapy (EVT) use increased following clinical trials publication in 2015, but limited data suggest there may be persistent race and ethnicity differences. Methods and Results We included all patients with acute ischemic stroke arriving within 6 hours of last known well and with National Institute of Health Stroke Scale (NIHSS) score ≥6 between April 2012 and June 2019 in the Get With The Guidelines-Stroke database and evaluated the association between race and ethnicity and EVT use and outcomes, comparing the era before versus after 2015. Of 302 965 potentially eligible patients; 42 422 (14%) underwent EVT. Although EVT use increased over time in all racial and ethnic groups, Black patients had reduced odds of EVT use compared with non-Hispanic White (NHW) patients (adjusted odds ratio [aOR] before 2015, 0.68 [0.58‒0.78]; aOR after 2015, 0.83 [0.76‒0.90]). In-hospital mortality/discharge to hospice was less frequent in Black, Hispanic, and Asian patients compared with NHW. Conversely discharge home was more frequent in Hispanic (29.7%; aOR, 1.28 [1.16‒1.42]), Asian (28.2%; aOR, 1.23 [1.05‒1.44]), and Black (29.1%; aOR, 1.08 [1.00‒1.18]) patients compared with NHW (24%). However, at 3 months, functional independence (modified Rankin Scale, 0-2) occurred less frequently in Black (37.5%; aOR, 0.84 [0.75‒0.95]) and Asian (33%; aOR, 0.79 [0.65‒0.98]) patients compared with NHW patients (38.1%). Conclusions In a large cohort of patients treated with EVT, Black versus NHW patient disparities in EVT use have narrowed over time but still exist. Discharge related outcomes were slightly more favorable in racial and ethnic underrepresented groups; 3-month functional outcomes were worse but improved across all groups with time.

Project description:OBJECTIVE:To investigate disparities in mental health care episodes, aligning our analyses with decisions to start or drop treatment, and choices made during treatment. STUDY DESIGN:We analyzed whites, blacks, and Latinos with probable mental illness from Panels 9-13 of the Medical Expenditure Panel Survey, assessing disparities at the beginning, middle, and end of episodes of care (initiation, adequate care, having an episode with only psychotropic drug fills, intensity of care, the mixture of primary care provider (PCP) and specialist visits, use of acute psychiatric care, and termination). FINDINGS:Compared with whites, blacks and Latinos had less initiation and adequacy of care. Black and Latino episodes were shorter and had fewer psychotropic drug fills. Black episodes had a greater proportion of specialist visits and Latino episodes had a greater proportion of PCP visits. Blacks were more likely to have an episode with acute psychiatric care. CONCLUSIONS:Disparities in adequate care were driven by initiation disparities, reinforcing the need for policies that improve access. Many episodes were characterized only by psychotropic drug fills, suggesting inadequate medication guidance. Blacks' higher rate of specialist use contradicts previous studies and deserves future investigation. Blacks' greater acute mental health care use raises concerns over monitoring of their treatment.

Project description:ObjectiveTo evaluate the association of race-ethnicity and neighborhood socioeconomic status with adherence to National Comprehensive Cancer Network guidelines for endometrial carcinoma.MethodsData are from the SEER (Surveillance, Epidemiology, and End Results) cancer registry of women diagnosed with endometrial carcinoma for the years 2006-2015. The sample included 83,883 women after inclusion and exclusion criteria were applied. Descriptive statistics, bivariate analyses, univariate, and multivariate logistic regression models were performed to evaluate the association between race-ethnicity and neighborhood socioeconomic status with adherence to treatment guidelines.ResultsAfter controlling for demographic and clinical covariates, Black (odds ratio [OR] 0.89, P<.001), Latina (OR .92, P<.001), and American Indian or Alaska Native (OR 0.82, P=.034) women had lower odds of receiving adherent treatment and Asian (OR 1.14, P<.001) and Native Hawaiian or Pacific Islander (OR 1.19 P=.012) women had higher odds of receiving adherent treatment compared with White women. After controlling for covariates, there was a gradient by neighborhood socioeconomic status: women in the high-middle (OR 0.89, P<.001), middle (OR 0.84, P<.001), low-middle (OR 0.80, P<.001), and lowest (OR 0.73, P<.001) neighborhood socioeconomic status categories had lower odds of receiving adherent treatment than the those in the highest neighborhood socioeconomic status group.ConclusionsFindings from this study suggest there are racial-ethnic and neighborhood socioeconomic disparities in National Comprehensive Cancer Network treatment adherence for endometrial cancer. Standard treatment therapies should not differ based on sociodemographics. Interventions are needed to ensure that equitable cancer treatment practices are available for all individuals, regardless of racial-ethnic or socioeconomic background.

Project description:To evaluate disparities in substance abuse treatment completion between and within racial and ethnic groups in publicly funded treatment in Los Angeles County, California.The Los Angeles County Participant Reporting System with multicross-sectional annual data (2006-2009) for adult participants (n = 16,637) who received treatment from publicly funded programs (n = 276) for the first time.Retrospective analyses of county discharge and admission data. Hierarchical linear regressions models were used to test the hypotheses.Client data were collected during personal interviews at admission and discharge for most participants.African Americans and Latinos reported lower odds of completing treatment compared with Whites. Within-group analysis revealed significant heterogeneity within racial and ethnic groups, highlighting primary drug problem, days of drug use before admission, and homelessness as significant factors affecting treatment completion. Service factors, such as referral by the criminal justice system, enabled completion among Latinos and Whites only.These findings have implications for reducing health disparities among members of racial and ethnic minorities by identifying individual and service factors associated with treatment adherence, particularly for first-time clients.
