ABSTRACT: Introduction
At the population level, Black and Hispanic adults in the United States have increased risk of dying from COVID-19, yet whether race and ethnicity impact on risk of mortality among those hospitalized for COVID-19 is unclear.Methods
Retrospective cohort study using data on adults hospitalized with COVID-19 from the electronic health record from 52 health systems across the United States contributing data to Cerner Real World DataTM. In-hospital mortality was evaluated by race first in unadjusted analysis then sequentially adjusting for demographics and clinical characteristics using logistic regression.Results
Through August 2020, 19,584 patients with median age 52 years were hospitalized with COVID-19, including n = 4,215 (21.5%) Black and n = 5,761 (29.4%) Hispanic patients. Relative to white patients, crude mortality was slightly higher in Black adults [22.7% vs 20.8%, unadjusted OR 1.12 (95% CI 1.02-1.22)]. Mortality remained higher among Black adults after adjusting for demographic factors including age, sex, date, region, and insurance status (OR 1.13, 95% CI 1.01-1.27), but not after including comorbidities and body mass index (OR 1.07, 95% CI 0.93-1.23). Compared with non-Hispanic patients, Hispanic patients had lower mortality both in unadjusted and adjusted models [mortality 12.7 vs 25.0%, unadjusted OR 0.44(95% CI 0.40-0.48), fully adjusted OR 0.71 (95% CI 0.59-0.86)].Discussion
In this large, multicenter, EHR-based analysis, Black adults hospitalized with COVID-19 had higher observed mortality than white patients due to a higher burden of comorbidities in Black adults. In contrast, Hispanic ethnicity was associated with lower mortality, even in fully adjusted models.

Project description:BackgroundThe impact of race and socioeconomic status on clinical outcomes has not been quantified in patients hospitalized with coronavirus disease 2019 (COVID-19).ObjectiveTo evaluate the association between patient sociodemographics and neighborhood disadvantage with frequencies of death, invasive mechanical ventilation (IMV), and intensive care unit (ICU) admission in patients hospitalized with COVID-19.DesignRetrospective cohort study.SettingFour hospitals in an integrated health system serving southeast Michigan.ParticipantsAdult patients admitted to the hospital with a COVID-19 diagnosis confirmed by polymerase chain reaction.Main measuresPatient sociodemographics, comorbidities, and clinical outcomes were collected. Neighborhood socioeconomic variables were obtained at the census tract level from the 2018 American Community Survey. Relationships between neighborhood median income and clinical outcomes were evaluated using multivariate logistic regression models, controlling for patient age, sex, race, Charlson Comorbidity Index, obesity, smoking status, and living environment.Key resultsBlack patients lived in significantly poorer neighborhoods than White patients (median income: $34,758 (24,531-56,095) vs. $63,317 (49,850-85,776), p < 0.001) and were more likely to have Medicaid insurance (19.4% vs. 11.2%, p < 0.001). Patients from neighborhoods with lower median income were significantly more likely to require IMV (lowest quartile: 25.4%, highest quartile: 16.0%, p < 0.001) and ICU admission (35.2%, 19.9%, p < 0.001). After adjusting for age, sex, race, and comorbidities, higher neighborhood income ($10,000 increase) remained a significant negative predictor for IMV (OR: 0.95 (95% CI 0.91, 0.99), p = 0.02) and ICU admission (OR: 0.92 (95% CI 0.89, 0.96), p < 0.001).ConclusionsNeighborhood disadvantage, which is closely associated with race, is a predictor of poor clinical outcomes in COVID-19. Measures of neighborhood disadvantage should be used to inform policies that aim to reduce COVID-19 disparities in the Black community.

Project description:BackgroundOlder adults and people from certain racial and ethnic groups are disproportionately represented in coronavirus disease 2019 (COVID-19) hospitalizations and deaths.MethodsUsing data from the Premier Healthcare Database on 181 813 hospitalized adults diagnosed with COVID-19 during March-September 2020, we applied multivariable log-binomial regression to assess the associations between age and race/ethnicity and COVID-19 clinical severity (intensive care unit [ICU] admission, invasive mechanical ventilation [IMV], and death) and to determine whether the impact of age on clinical severity differs by race/ethnicity.ResultsOverall, 84 497 (47%) patients were admitted to the ICU, 29 078 (16%) received IMV, and 27 864 (15%) died in the hospital. Increased age was strongly associated with clinical severity when controlling for underlying medical conditions and other covariates; the strength of this association differed by race/ethnicity. Compared with non-Hispanic White patients, risk of death was lower among non-Hispanic Black patients (adjusted risk ratio, 0.96; 95% CI, 0.92-0.99) and higher among Hispanic/Latino patients (risk ratio [RR], 1.15; 95% CI, 1.09-1.20), non-Hispanic Asian patients (RR, 1.16; 95% CI, 1.09-1.23), and patients of other racial and ethnic groups (RR, 1.13; 95% CI, 1.06-1.21). Risk of ICU admission and risk of IMV were elevated among some racial and ethnic groups.ConclusionsThese results indicate that age is a driver of poor outcomes among hospitalized persons with COVID-19. Additionally, clinical severity may be elevated among patients of some racial and ethnic minority groups. Public health strategies to reduce severe acute respiratory syndrome coronavirus 2 infection rates among older adults and racial and ethnic minorities are essential to reduce poor outcomes.

Project description:BackgroundWhether HIV infection is associated with differences in clinical outcomes among people hospitalized with COVID-19 is uncertain.ObjectiveTo evaluate the impact of HIV infection on COVID-19 outcomes among hospitalized patients.MethodsUsing the American Heart Association's COVID-19 Cardiovascular Disease registry, we used hierarchical mixed effects models to assess the association of HIV with in-hospital mortality accounting for patient demographics and comorbidities and clustering by hospital. Secondary outcomes included major adverse cardiac events (MACE), severity of illness, and length of stay (LOS).ResultsThe registry included 21,528 hospitalization records of people with confirmed COVID-19 from 107 hospitals in 2020, including 220 people living with HIV (PLWH). PLWH were younger (56.0+/-13.0 versus 61.3+/-17.9 years old) and more likely to be male (72.3% vs 52.7%), Non-Hispanic Black (51.4% vs 25.4%), on Medicaid (44.5% vs 24.5), and active tobacco users (12.7% versus 6.5%).Of the study population, 36 PLWH (16.4%) had in-hospital mortality compared with 3,290 (15.4%) without HIV (Risk ratio 1.06, 95%CI 0.79-1.43; risk difference 0.9%, 95%CI -4.2 to 6.1%; p=0.71). After adjustment for age, sex, race, and insurance, HIV was not associated with in-hospital mortality (aOR 1.13; 95%CI 0.77-1.6; p 0.54) even after adding body mass index and comorbidities (aOR 1.15; 95%CI 0.78-1.70; p=0.48). HIV was not associated with MACE (aOR 0.99, 95%CI 0.69-1.44, p=0.91), severity of illness (aOR 0.96, 95%CI 0.62-1.50, p=0.86), or LOS (aOR 1.03; 95% CI 0.76-1.66, p=0.21).ConclusionHIV was not associated with adverse outcomes of COVID-19 including in-hospital mortality, MACE, or severity of illness.Condensed abstractWe studied 21,528 patients hospitalized with COVID-19 at 107 hospitals in AHA's COVID-19 registry to examine the association between HIV and COVID-19 outcomes. More patients with HIV were younger, male, non-Hispanic Black, on Medicaid and current smokers. HIV was not associated with worse COVID-19 in-hospital mortality (Risk ratio 1.06, 95%CI 0.79-1.43; p=0.71) even after adjustment (aOR 1.15; 95%CI 0.78-1.70; p=0.48). HIV was also not associated with MACE (aOR 0.99, 95%CI 0.69-1.44, p=0.91) or severity of illness (aOR 0.96, 95%CI 0.62-1.50, p=0.86. Our findings do not support that HIV is a major risk factor for adverse COVID-19 outcomes.

Project description:ObjectivesAlthough racial/ethnic disparities in healthcare have long been recognized, recent discourse around structural racism will hopefully lead to improved transparency surrounding these issues. Despite the disproportionate impact of COVID-19 on racial/ethnic minorities, the extent and reliability of race reporting in COVID research is unclear.MethodsCOVID-19 research published in three top medical journals during the first wave of the COVID-19 pandemic was reviewed and assessed for race reporting and proportional representation.ResultsOf the 95 manuscripts that were identified, 56 reporting on 252,262 patients met eligibility. Thirty-five (62.5%) did not report race distribution and 15 (26.7%) did not report ethnicity. There was no difference based on journal (P = 0.87), study sponsor (P = 0.41), whether the study was retrospective or prospective (P = 0.33), or observational vs interventional (P = 0.11). Studies with ≥250 patients were more likely to report on race (OR 4.01, 95% CI: 1.12-14.37, P = 0.027), and North American (USA and Canada) studies were more likely than European studies (OR 7.88, 95% CI: 1.73-37.68, P = 0.006) to report on race. COVID-19 research mirrored USA COVID-19 racial incidence; however, both showed higher distribution of COVID-19 infection among Blacks and a smaller proportion of Whites compared to the USA population. This suggests that research is broadly representing infection rates and that social determinants of health are impacting racial distribution of infection.ConclusionsDespite increasing awareness of racial disparities and inequity, COVID-19 research during the first wave of the pandemic lacked appropriate racial/ethnicity reporting. However, research mirrored COVID-19 incidence in the USA, with an increased burden of infection among Black individuals.

Project description:Research examining whether intentions to get a COVID-19 vaccine change over time is scarce. Moreover, the deep and pervasive history of medical racism in the U.S. has created a context in which some racial and ethnic groups exhibit greater levels of COVID-19 vaccine hesitancy; yet few researchers have attempted to determine whether these patterns persist with time. The purpose of this study was twofold: (a.) assess the role of time in COVID-19 vaccine intentions from April 2020 to January 2021, and (b.) examine whether race and ethnicity shape COVID-19 vaccine intention trajectories. Data were drawn from 9 waves of the Understanding America Study (n = 5023), a national probability panel study of U.S. adults. Multilevel logistic regression models were used to assess overall COVID-19 vaccine intention trajectories and trajectories by race and ethnicity. Results demonstrate intentions to get a COVID-19 vaccine significantly decreased from April 2020 to November 2020, but by January 2021, intentions to get a COVID-19 vaccine slightly increased. Findings also show trajectories significantly differed by racial and ethnic background. Asian/Pacific Islanders had the highest probability of likely getting a COVID-19 vaccine at baseline, followed by Whites and Latina/os. Black Americans exhibited the lowest probability of likely getting vaccinated, and, in most cases, the gap between Black Americans and other racial groups grew over time. Key findings from this study demonstrate that, among U.S. adults, time and race and ethnicity play significant roles in COVID-19 vaccine intentions. Understanding the role of time and race and racism in shaping COVID-19 vaccine intention trajectories can help government agencies and public health experts tasked with administrating vaccines better understand disparities in vaccine uptake.

Project description:ObjectivesWe investigated the predictors of functional outcome in young patients enrolled in a multiethnic study of intracerebral hemorrhage (ICH).MethodsThe Ethnic/Racial Variations in Intracerebral Hemorrhage (ERICH) study is a prospective multicenter study of ICH among adult (age ≥18 years) non-Hispanic white, non-Hispanic black, and Hispanic participants. The study recruited 1,000 participants per racial/ethnic group. The present study utilized the subset of ERICH participants aged <50 years with supratentorial ICH. Functional outcome was ascertained using the modified Rankin Scale (mRS) at 3 months. Logistic regression was used to identify factors associated with poor outcome (mRS 4-6), and analyses were compared by race/ethnicity to identify differences across these groups.ResultsOf the 3,000 patients with ICH enrolled in ERICH, 418 were studied (mean age 43 years, 69% male), of whom 48 (12%) were white, 173 (41%) were black, and 197 (47%) were Hispanic. For supratentorial ICH, black participants (odds ratio [OR], 0.42; p = 0.046) and Hispanic participants (OR, 0.34; p = 0.01) had better outcomes than white participants after adjustment for other factors associated with poor outcome: age, baseline disability, admission blood pressure, admission Glasgow Coma Scale score, ICH volume, deep ICH location, and intraventricular extension.ConclusionsIn young patients with supratentorial ICH, black and Hispanic race/ethnicity is associated with better functional outcomes, compared with white race. Additional studies are needed to identify the biological and social mediators of this association.

Project description:(1) Background: This work aims to analyze clinical outcomes according to ethnic groups in patients hospitalized for COVID-19 in Spain. (2) Methods: This nationwide, retrospective, multicenter, observational study analyzed hospitalized patients with confirmed COVID-19 in 150 Spanish hospitals (SEMI-COVID-19 Registry) from 1 March 2020 to 31 December 2021. Clinical outcomes were assessed according to ethnicity (Latin Americans, Sub-Saharan Africans, Asians, North Africans, Europeans). The outcomes were in-hospital mortality (IHM), intensive care unit (ICU) admission, and the use of invasive mechanical ventilation (IMV). Associations between ethnic groups and clinical outcomes adjusted for patient characteristics and baseline Charlson Comorbidity Index values and wave were evaluated using logistic regression. (3) Results: Of 23,953 patients (median age 69.5 years, 42.9% women), 7.0% were Latin American, 1.2% were North African, 0.5% were Asian, 0.5% were Sub-Saharan African, and 89.7% were European. Ethnic minority patients were significantly younger than European patients (median (IQR) age 49.1 (40.5-58.9) to 57.1 (44.1-67.1) vs. 71.5 (59.5-81.4) years, p < 0.001). The unadjusted IHM was higher in European (21.6%) versus North African (11.4%), Asian (10.9%), Latin American (7.1%), and Sub-Saharan African (3.2%) patients. After further adjustment, the IHM was lower in Sub-Saharan African (OR 0.28 (0.10-0.79), p = 0.017) versus European patients, while ICU admission rates were higher in Latin American and North African versus European patients (OR (95%CI) 1.37 (1.17-1.60), p < 0.001) and (OR (95%CI) 1.74 (1.26-2.41), p < 0.001). Moreover, Latin American patients were 39% more likely than European patients to use IMV (OR (95%CI) 1.43 (1.21-1.71), p < 0.001). (4) Conclusion: The adjusted IHM was similar in all groups except for Sub-Saharan Africans, who had lower IHM. Latin American patients were admitted to the ICU and required IMV more often.

Project description:BackgroundThe COVID-19 pandemic disrupted health care delivery, including cancer screening practices. This study sought to determine the impact of the COVID-19 pandemic lockdown on colorectal cancer (CRC) screening relative to social vulnerability.MethodsUsing the Medicare Standard Analytic File, individuals 65 years old or older who were eligible for guideline-concordant CRC screening between 2019 and 2021 were identified. These data were merged with the Center for Disease Control Social Vulnerability Index (SVI) dataset. Changes in county-level monthly screening volumes relative to the start of the COVID-19 pandemic (March 2020) and easing of restrictions (March 2021) were assessed relative to SVI.ResultsAmong 10,503,180 individuals continuously enrolled in Medicare with no prior diagnosis of CRC, 1,362,457 (12.97%) underwent CRC screening between 2019 and 2021. With the COVID-19 pandemic, CRC screening decreased markedly across the United States (median monthly screening: pre-pandemic [n = 76,444] vs pandemic era [n = 60,826]; median Δn = 15,618; p < 0.001). The 1-year post-pandemic overall CRC screening utilization generally rebounded to pre-COVID-19 levels (monthly median screening volumes: pandemic era [n = 60,826] vs post-pandemic [n = 74,170]; median Δn = 13,344; p < 0.001). Individuals residing in counties with the highest SVI experienced a larger decline in CRC screening odds than individuals residing in low-SVI counties (reference, low SVI: pre-pandemic high SVI [OR, 0.85] vs pandemic high SVI [OR, 0.81] vs post-pandemic high SVI [OR, 0.85]; all p < 0.001).ConclusionsThe COVID-19 pandemic was associated with a decrease in CRC screening volumes. Patients who resided in high social vulnerability areas experienced the greatest pandemic-related decline.

Project description:COVID-19 vaccines are an effective tool in preventing severe disease. Most states used an age-based prioritization for vaccine rollout. We examined the impact of a primarily age-based prioritization policy on reductions of severe disease in different racial and ethnic groups. We calculated age-specific rates of COVID-19 hospitalization and death by race/ethnicity in Denver, Colorado. To assess potentially averted hospitalizations and deaths by race/ethnicity, we then applied the first three phases of Colorado's primarily age-based vaccine rollout criteria to historical 2020 COVID-19 hospitalizations and deaths in Denver, Colorado. In the first 3 phases, 40% (1403/3473) of hospitalizations and 83% (503/604) of deaths occurred among those meeting age and long-term care facility criteria and could have been averted. Impacts varied by race/ethnicity with only 28% (440/1587) of hospitalizations and 74% (131/178) of deaths averted among Hispanic or Latino residents, compared to 57% (619/1094) of hospitalizations and 92% (252/274) of deaths among non-Hispanic White residents. We demonstrate using local data and policy that early age-based prioritization decisions disproportionately promoted reductions in severe disease among non-Hispanic White residents irrespective of COVID-19 risk in Denver, Colorado. These findings suggest that more equitable future vaccine prioritization policies, which lead with a goal of reducing health disparities through prioritizing susceptibility to adverse health outcomes rather than overall population-based cutoffs, are necessary. Our results have implications for future vaccination rollouts in limited vaccine resource conditions.

Project description:BackgroundThe COVID-19 pandemic has affected all people across the globe. Regional and community differences in timing and severity of surges throughout the pandemic can provide insight into risk factors for worse outcomes in those hospitalized with COVID-19.MethodsThe study cohort was derived from the Cerner Real World Data (CRWD) COVID-19 Database made up of hospitalized patients with proven infection from December 1, 2019 through November 30, 2020. Baseline demographic information, comorbidities, and hospital characteristics were obtained. We performed multivariate analysis to determine if age, race, comorbidity and regionality were predictors for mortality, ARDS, mechanical ventilation or sepsis hospitalized patients with COVID-19.ResultsOf 100,902 hospitalized COVID-19 patients included in the analysis (median age 52 years, IQR 36-67; 50.7% female), COVID-19 case fatality rate was 8.5% with majority of deaths in those ≥ 65 years (70.8%). In multivariate analysis, age ≥ 65 years, male gender and higher Charlson Comorbidity Index (CCI) were independent risk factors for mortality and ARDS. Those identifying as non-Black or non-White race have a marginally higher risk for mortality (OR 1.101, CI 1.032-1.174) and greater risk of ARDS (OR 1.44, CI 1.334-1.554) when compared to those who identify as White. The risk of mortality or ARDS was similar for Blacks as Whites. Multivariate analysis found higher mortality risk in the Northeast (OR 1.299, CI 1.22-1.29) and West (OR 1.26, CI 1.18-1.34). Larger hospitals also had an increased risk of mortality, greatest in hospitals with 500-999 beds (OR 1.67, CI 1.43-1.95).ConclusionAdvanced age, male sex and a higher CCI predicted worse outcomes in hospitalized COVID-19 patients. In multivariate analysis, worse outcomes were identified in small minority populations, however there was no difference in study outcomes between those who identify as Black or White.
