In-Hospital Mortality Disparities Among American Indian and Alaska Native, Black, and White Patients With COVID-19.

Importance: American Indian and Alaska Native populations have some of the highest COVID-19 hospitalization and mortality rates in the US, with those in Mississippi being disparately affected. Higher COVID-19 mortality rates among Indigenous populations are often attributed to a higher comorbidity burden, although examinations of these associations are scarce, and none were believed to have included individuals hospitalized in Mississippi. Objective: To evaluate whether racial mortality differences among adults hospitalized with COVID-19 are associated with differential comorbidity experiences. Design, Setting, and Participants: The described cross-sectional study used retrospective hospital discharge data from the Mississippi Inpatient Outpatient Data System. All adult (aged ≥18 years) Mississippians of a known racial identity and who had been hospitalized with COVID-19 from March 1 to December 31, 2020, in any of the state's 103 nonfederal hospitals were included. Data were abstracted on June 17, 2021. Exposure: Racial identity. Main Outcomes and Measures: In-hospital mortality as indicated by discharge status. Results: A total of 18 731 adults hospitalized with a COVID-19 diagnosis and known racial identity were included (median age, 66 [IQR, 53-76] years; 10 109 [54.0%] female; 225 [1.2%] American Indian and Alaska Native; 9191 [49.1%] Black; and 9121 [48.7%] White). Pooling across comorbidity risk groups, odds of in-hospital mortality among Black patients were 75% lower than among American Indian and Alaska Native patients (odds ratio [OR], 0.25 [95% CI, 0.18-0.34]); odds of in-hospital death among White patients were 77% lower (OR, 0.23 [95% CI, 0.16-0.31]). Within comorbidity risk group analyses, Indigenous patients with the lowest risk (Elixhauser Comorbidity Index score ≤0) had an adjusted probability of in-hospital death of 0.10 compared with 0.03 for Black patients (OR, 0.29 [95% CI, 0.10-0.82]) and 0.04 for White patients (OR, 0.37 [95% CI, 0.13-1.07]). Probability of in-hospital death at the highest comorbidity risk levels (Elixhauser Comorbidity Index score ≥16) was 0.69 for American Indian and Alaska Native patients compared with 0.28 for Black patients (OR, 0.16 [95% CI, 0.08-0.32]) and 0.25 for White patients (OR, 0.14 [95% CI, 0.07-0.27]). Conclusions and Relevance: This cross-sectional study of US adults hospitalized with COVID-19 found that American Indian and Alaska Native patients had lower comorbidity risk scores than those observed among Black or White patients. Despite empirical associations between reduced comorbidity risk scores and reduced odds of inpatient mortality, American Indian and Alaska Native patients were significantly more likely to die in the hospital of COVID-19 than Black or White patients at every level of comorbidity risk. Alternative factors that may contribute to high mortality rates among Indigenous populations must be investigated.

COVID-19 Inpatient Mortality Disparities Among American Indian Adults in Mississippi's Safety Net Hospital.

BACKGROUND: Long-standing health disparities experienced by American Indians (AIs) are associated with increased all-cause mortality rates and shortened life expectancies when compared to other races and ethnicities. Nationally, these disparities have persisted with the COVID-19 pandemic as AIs are more likely than all other races to be infected, hospitalized, or die from SARS-CoV-2. The Mississippi Band of Choctaw Indians, the only federally recognized American Indian tribe in the state, has been one of the hardest hit in the nation. METHODS: Using de-identified data from the University of Mississippi Medical Center's COVID-19 Research Registry, a retrospective cohort study was conducted to assess COVID-19 inpatient mortality outcomes among adults (≥ age 18) admitted at the state's safety net hospital in 2020. RESULTS: Exactly 41% (n = 25) of American Indian adults admitted with a deemed diagnosis of COVID-19 died while in hospital, in comparison to 19% (n = 153) of blacks and 23% (n = 65) of whites. Racial disparities persisted even when controlling for those risk factors the CDC reported put adults at greatest risk of severe outcomes from the disease. The adjusted probability of inpatient mortality among American Indians was 46% (p < 0.00) in comparison to 19% among blacks and 20% among whites. CONCLUSION: Although comorbidities were commonly observed among COVID-19 + American Indian inpatients, only one was associated with inpatient mortality. This challenges commonly cited theories attributing disparate COVID-19 mortality experiences among indigenous populations to disparate comorbidity experiences. Expanded studies are needed to further investigate these associations.

Strengthening the clinical research workforce through a competency-based orientation program: Process outcomes and lessons learned across three academic health institutions.

Clinical research coordinators are increasingly tasked with a multitude of complex study activities critical to scientific rigor and participant safety, though more than half report not receiving appropriate training. To determine the reproducibility of an established clinical research workforce orientation program, collaborative partners across Clinical and Translational Science Award institutions seeded core principles and structure from Mayo Clinic's Clinical Research Orientation program within Penn State University and the University of Mississippi Medical Center from 2019 to 2021. Training concepts were established and tied to those domains deemed critical by the Joint Task Force for Clinical Trial Competency for the conduct of clinical research at the highest levels of safety and quality possible. Significant knowledge and confidence gains and high overall program satisfaction were reported across participants and partner sites, despite programs being required to pivot from traditional, in-person formats to entirely virtual platforms as a result of the COVID-19 pandemic. The successful standardization and translation of foundational clinical research training has important efficiency and efficacy implications for research enterprises across the USA.

Associations between sleep and academic performance in US adolescents: a systematic review and meta-analysis.

This systematic review and meta-analysis aim to investigate the relationship between sleep and academic performance in students enrolled in secondary education programs in the United States. The study team conducted a literature search of 4 databases-PubMed, Embase, CINAHL, and ERIC-on September 19 and repeated December 17, 2020. Studies were included if they were observational, published in a peer-reviewed, non-predatory journal, available in full-text, written in English, included adolescents enrolled in an organized academic program, took place in the US, and evaluated the effect of sleep duration and/or sleep quality on academic performance. After excluding reviews, editorials, interventions, and those targeting diagnostic groups, 14 studies met inclusion criteria. Risk of bias was assessed using the NIH Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies; 12 studies were found to be good or high quality, 2 were adequate/fair or poor quality. A meta-analysis of 11 of the included studies revealed that sleep duration (r = 0.03; 95%CI -0.027, 0.087; p = 0.087) and sleep quality (r = 0.089; 95%CI 0.027, 0.151; p = 0.005) had negligible correlations with academic performance (non-significant and significant, respectively). Inconsistencies in definitions, methods, and measures utilized to assess sleep duration, sleep quality, and academic performance constructs may offer insight into seemingly conflicting findings. Given the pivotal role sleep plays in development, future investigations utilizing validated and objective sleep and academic performance measures are needed in adolescents.
