Project description:OBJECTIVE:To assess racial/ethnic differential impacts of the ACA's Medicaid expansion on low-income, nonelderly adults' access to primary care. DATA SOURCES:Behavioral Risk Factor Surveillance System, State Physicians Workforce Data Book, and Bureau of Labor Statistics, in 2013 and 2015. STUDY DESIGN:Quasi-experimental design with difference-in-differences analyses. Outcomes included health insurance coverage, having personal doctor(s), being unable to see doctors because of cost, and receiving a flu shot. We tested racial/ethnic differential impacts using the "Seemingly unrelated estimation" method. Multiple imputations and survey weights were used. DATA COLLECTION/EXTRACTION METHODS:Low-income, nonelderly adults were identified based on age, household income, and family size. PRINCIPAL FINDINGS:Among the low-income, nonelderly adults, Medicaid expansion was associated with statistically significant gains in health insurance coverage, having personal doctors, and affordability. Hispanics got the fewest benefits, which significantly widened racial/ethnic disparities for the Hispanic group. Racial/ethnic disparity in having personal doctors narrowed for non-Hispanic black and non-Hispanic others, although not statistically significant. CONCLUSION:Medicaid expansion improved access to primary care, but it had differential effects among racial/ethnic groups resulting in mixed effects on disparities. Further research is necessary to develop tailored policy tools for racial/ethnic groups.

Project description:BackgroundIntracerebral hemorrhage (ICH) is associated with an increased risk of ischemic stroke. Whether there are racial and ethnic disparities in the risk of ischemic stroke after ICH is poorly understood. We therefore aimed to test the hypothesis that non-Hispanic Black and Hispanic ICH patients have a higher risk of ischemic stroke compared with non-Hispanic White ICH patients.MethodsWe performed a retrospective cohort study using the Healthcare Cost and Utilization Project (HCUP) on all hospitalizations at all nonfederal hospitals in Florida from 2005 to 2018 and New York from 2006 to 2016. Race and ethnicity were coded as a single variable in HCUP. We included patients with an ICH, and without a prior or concomitant diagnosis of ischemic stroke, ascertained using validated International Classification of Diseases-Clinical Modification-9 and 10 diagnosis codes. Using Cox proportional hazard models, we studied the relationship between race and risk of ischemic stroke starting from the time of discharge from ICH hospitalization, after adjustment of demographics and vascular comorbidities.ResultsWe included 91 342 patients with ICH-62% non-Hispanic White, 18% non-Hispanic Black, and 12% Hispanic patients. Non-Hispanic Black and Hispanic patients were younger and had a higher prevalence of cardiovascular comorbidities; however, atrial fibrillation was more prevalent among non-Hispanic White patients. During a median follow-up period of 4.4 years (interquartile range, 1.5-8.1), an incident ischemic stroke occurred in 3377 (6%) non-Hispanic White, 1323 (8%) non-Hispanic Black, and 844 (8%) Hispanic patients. In adjusted Cox models, the risk of an ischemic stroke was significantly higher among non-Hispanic Black patients (hazard ratio, 1.6 [95% CI, 1.5-1.8]) and Hispanic patients (hazard ratio, 1.4 [95% CI, 1.3-1.5]), compared with non-Hispanic White patients. Similar results were obtained in sensitivity analyses when using death as a competing risk and after excluding patients with atrial fibrillation and valvular heart disease.ConclusionsIn a large heterogeneous cohort of patients with ICH, we found that non-Hispanic Black and Hispanic patients had a significantly higher risk of ischemic stroke compared with non-Hispanic White patients.

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:ObjectivesTo investigate the association between short-term changes in ambient pollution (particulate matter <2.5 μm in aerodynamic diameter (PM2.5) and ozone (O3)) and the risk of ischemic stroke among individuals living in a bi-ethnic community and whether this association is modified by ethnicity.MethodsWe identified incident ischemic stroke cases from the population-based Brain Attack Surveillance in Corpus Christi (BASIC) project between 2000 and 2012. Associations between PM2.5 (mean 24-h) and O3 (maximal 8-h) levels, measured on the same-day and lags of 1-3 days, and odds of ischemic stroke were assessed using a time-stratified case-crossover design and modeled using conditional logistic regression. We explored race/ethnicity (Mexican American versus non-Hispanic white) as a modifier by including interaction terms in the models.ResultsThere were 2948 ischemic strokes with median age 71 years (IQR: 59-80). We observed no overall associations between the air pollutants and odds of ischemic stroke at any lag. When stratified by ethnicity, higher O3 was consistently associated with greater odds of ischemic stroke for non-Hispanic whites, but not for Mexican Americans. Higher PM2.5 was generally associated with lower odds of ischemic stroke for non-Hispanic whites but modestly greater odds for Mexican Americans.ConclusionEthnic differences in the associations between ischemic stroke and short-term exposures to O3 and PM2.5 were suggested indicating that further study in diverse populations may be warranted.

Project description:ObjectivesWe estimated racial/ethnic differences in attention-deficit/hyperactivity disorder (ADHD) care quality and treatment continuity among Medicaid-enrolled children.MethodsUsing Medicaid data from 9 states (2008 to 2011), we identified 172 322 youth (age 6 to 12) initiating ADHD medication. Outcome measures included: (1) adequate follow-up care in the (a) initiation and (b) continuation and maintenance (C&M) treatment phases; (2) combined treatment with medication and psychotherapy (versus medication alone); (3) medication discontinuation; and (4) treatment disengagement (ie, discontinued medication and received no psychotherapy). Logistic regressions controlled for confounding measures.ResultsAmong those initiating medication, three-fifths received adequate follow-up care in the initiation and C&M phases, and under two-fifths received combined treatment. Compared with whites, African American youth were less likely to receive adequate follow-up in either phase (P < .05), whereas Hispanic youth were more likely to receive adequate follow-up in the C&M phase (P < .001). African American and Hispanic youth were more likely than whites to receive combined treatment (P < .05). Over three-fifths discontinued medication, and over four-tenths disengaged from treatment. Compared with whites, African American and Hispanic children were 22.4% and 16.7% points more likely to discontinue medication, and 13.1% and 9.4% points more likely to disengage from treatment, respectively (P < .001).ConclusionsCare quality for Medicaid-enrolled youth initiating ADHD medication is poor, and racial/ethnic differences in these measures are mixed. The most important disparities occur in the higher rates of medication discontinuation among minorities, which translate into higher rates of treatment disengagement because most youth discontinuing medication receive no psychotherapy.

Project description:BackgroundBlack patients are commonly believed to have higher stroke mortality. However, several recent studies have reported better survival in black patients with stroke.ObjectiveTo examine racial differences in stroke mortality and explore potential reasons for these differences.DesignObservational cohort study.Setting164 hospitals in New York.Participants5319 black and 18 340 white patients aged 18 years or older who were hospitalized with acute ischemic stroke between January 2005 and December 2006.MeasurementsInfluence of race on mortality, examined by using propensity score analysis. Secondary outcomes were selected aspects of end-of-life treatment, use of tissue plasminogen activator, hospital spending, and length of stay. Patients were followed for mortality for 1 year after admission.ResultsOverall in-hospital mortality was lower for black patients than for white patients (5.0% vs. 7.4%; P < 0.001), as was all-cause mortality at 30 days (6.1% vs. 11.4%; P < 0.001) and 1 year (16.5% vs. 24.4%; P < 0.001). After propensity score adjustment, black race was independently associated with lower in-hospital mortality (odds ratio [OR], 0.77 [95% CI, 0.61 to 0.98]) and all-cause mortality up to 1 year (OR, 0.86 [CI, 0.77 to 0.96]). The adjusted hazard ratio was 0.87 (CI, 0.79 to 0.96). After adjustment for the probability of dying in the hospital, black patients with stroke were more likely to receive life-sustaining interventions (OR, 1.22 [CI, 1.09 to 1.38]) but less likely to be discharged to hospice (OR, 0.25 [CI, 0.14 to 0.46]).LimitationsThe study used hospital administrative data that lacked a stroke severity measure. The study design precluded determination of causality.ConclusionAmong patients with acute ischemic stroke, black patients had lower mortality than white patients. This could be the result of differences in receipt of life-sustaining interventions and end-of-life care.

Project description:ObjectiveTo examine racial and ethnic disparities in the receipt of minimally adequate depression treatment in Medicaid-enrolled youth.MethodMedicaid claims data of 2008 through 2011 were used to derive a cohort of youth (5-17 years old) who were diagnosed with a new episode of major depression (N = 45,816) across 9 states. Dichotomous outcomes measured the receipt of minimally adequate psychotherapy (≥4 psychotherapy visits within 12 weeks of initiation); minimally adequate medication (filled antidepressants for 84 of 144 days); any minimally adequate treatment (psychotherapy or medication); and no psychotherapy or medication. Racial/ethnic disparities in the outcome measures were estimated using logistic regression models that controlled for predisposing, enabling, and need-related factors.ResultsLess than four-tenths (38.3%) of the cohort received minimally adequate psychotherapy, 19.2% received minimally adequate pharmacotherapy, and 49.9% received any minimally adequate treatment; conversely, 16.4% received no treatment. Adjusted percentages of black (42.3%; p < .001) and Hispanic (48.2%; p < .001) youth who received minimally adequate treatment were significantly smaller than for non-Hispanic whites (54.7%) because of lower likelihoods of receiving minimally adequate psychotherapy and/or minimally adequate pharmacotherapy. In addition, adjusted percentages of black (20.2%; p < .001) and Hispanic (15.0%; p < .01) youth who received no treatment were significantly larger than for non-Hispanic white youth (12.9%).ConclusionThe percentage of Medicaid-enrolled youth who receive minimally adequate treatment for depression is small overall and even smaller for racial/ethnic minorities than for whites. Future research is needed to identify strategies that improve the overall quality of depression treatment in Medicaid-enrolled youth and decrease disparities in care.

Project description:IntroductionAfter having an acute myocardial infarction (AMI), racial and ethnic minorities have less access to care, decreased rates of invasive treatments such as percutaneous coronary intervention (PCI), and worse outcomes compared with white patients. The objective of this study was to determine whether the Affordable Care Act's expansion of Medicaid eligibility was associated with changes in racial disparities in access, treatments, and outcomes after AMI.MethodsQuasi-experimental, difference-in-differences-in-differences analysis of non-Hispanic white and minority patients with acute myocardial infarction in California and Florida from 2010-2015, using linear regression models to estimate the difference-in-differences. This population-based sample included all Medicaid and uninsured patients ages 18-64 hospitalized with acute myocardial infarction in California, which expanded Medicaid through the Affordable Care Act beginning as early as July 2011 in certain counties, and Florida, which did not expand Medicaid. The main outcomes included rates of admission to hospitals capable of performing PCI, rates of transfer for patients who first presented to hospitals that did not perform PCI, rates of PCI during hospitalization and rates of early (within 48 hours of admission) PCI, rates of readmission to the hospital within 30 days, and rates of in-hospital mortality.ResultsA total of 55,991 hospital admissions met inclusion criteria, 32,540 of which were in California and 23,451 were in Florida. Among patients with AMI who initially presented to a non-PCI hospital, the likelihood of being transferred increased by 12 percentage points (95% CI 2 to 21) for minority patients relative to white patients after the Medicaid expansion. The likelihood of undergoing PCI increased by 3 percentage points (95% CI 0 to 5) for minority patients relative to white patients after the Medicaid expansion. We did not find an association between the Medicaid expansion and racial disparities in overall likelihood of admission to a PCI hospital, hospital readmissions, or in-hospital mortality.ConclusionsThe Medicaid expansion was associated with a decrease in racial disparities in transfers and rates of PCI after AMI. We did not find an association between the Medicaid expansion and admission to a PCI hospital, readmissions, and in-hospital mortality. Additional factors outside of insurance coverage likely continue to contribute to disparities in outcomes after AMI. These findings are crucial for policy makers seeking to reduce racial disparities in access, treatment and outcomes in AMI.

Project description:ImportanceHospice care enhances quality of life for people with terminal illness and is most beneficial with longer length of stay (LOS). Most hospice research focuses on the Medicare-insured population. Little is known about hospice use for the racially and ethnically diverse, low-income Medicaid population.ObjectiveTo compare hospice use and hospice LOS by race and ethnicity among Medicaid-only individuals and those with dual eligibility for Medicare and Medicaid (duals) in the Connecticut Medicaid program who died over a 4-year period.Design, setting, and participantsThis retrospective population-based cohort study used Medicaid and traditional Medicare enrollment and claims data for 2015 to 2020. The study included Connecticut Medicaid recipients with at least 1 of 5 most common hospice diagnoses who died from 2017 to 2020.ExposureRace and ethnicity.Main outcomes and measuresHospice use (yes/no) and hospice LOS (1-7 days vs ≥8 days.) Covariates included sex, age, and nursing facility stay within 60 days of death.ResultsOverall, 2407 and 23 857 duals were included. Medicaid-only decedents were younger (13.8% ≥85 vs 52.5%), more likely to be male (50.6% vs 36.4%), more racially and ethnically diverse (48.7% non-Hispanic White vs 79.9%), and less likely to have a nursing facility stay (34.9% vs 56.1%). Race and ethnicity were significantly associated with hospice use and LOS in both populations: non-Hispanic Black and Hispanic decedents had lower odds of using hospice than non-Hispanic White decedents, and Hispanic decedents had higher odds of a short LOS. In both populations, older age and female sex were also associated with more hospice use. For duals only, higher age was associated with lower odds of short LOS. For decedents with nursing facility stays, compared with those without, Medicaid-only decedents had higher odds of using hospice (odds ratio [OR], 1.49; 95% CI, 1.24-1.78); duals had lower odds (OR, 0.60; 95% CI, 0.57-0.63). Compared with decedents without nursing facility stays, duals with a nursing facility stay had higher odds of short LOS (OR, 2.63; 95% CI, 2.43-2.85).Conclusions and relevanceFindings raise concerns about equity and timing of access to hospice for Hispanic and non-Hispanic Black individuals in these understudied Medicaid populations. Knowledge about, access to, and acceptance of hospice may be lacking for these low-income individuals. Further research is needed to understand barriers to and facilitators of hospice use for people with nursing facility stays.

Project description:ObjectiveTo determine black-white differences in 1-year recurrent stroke and 30-day case fatality after a recurrent stroke in older US adults.MethodsWe conducted a retrospective cohort study using a 5% random sample of Medicare beneficiaries with fee-for-service health insurance coverage who were hospitalized for ischemic stroke between 1999 and 2013. Hazard ratios for recurrent ischemic stroke and risk ratios for 30-day case fatality comparing blacks to whites were calculated with adjustment for demographics, risk factors, and competing risk of death when appropriate.ResultsAmong 128,789 Medicare beneficiaries having an ischemic stroke (mean age 80 years [SD 8 years], 60.4% male), 11.1% were black. The incidence rate of recurrent ischemic stroke per 1,000 person-years for whites and blacks was 108 (95% confidence interval [CI], 106-111) and 154 (95% CI 147-162) , respectively. The multivariable-adjusted hazard ratio for recurrent stroke among blacks compared with whites was 1.36 (95% CI 1.29-1.44). The case fatality after recurrent stroke for blacks and whites was 21% (95% CI 21%-22%) and 16% (95% CI 15%-18%), respectively. The multivariable-adjusted relative risk for mortality within 30 days of a recurrent stroke among blacks compared with whites was 0.82 (95% CI 0.73-0.93).ConclusionThe risk of stroke recurrence among older Americans hospitalized for ischemic stroke is higher for blacks compared to whites, while 30-day case fatality after recurrent stroke remains lower for blacks.
