A Nationwide Comparison of Outcomes and Resource Use in Staged vs Simultaneous Cervical and Lumbar Fusions: A Retrospective Database Study

Background: Although the coexistence of cervical and lumbar spinal conditions is fairly common, surgical treatments are usually staged, even though simultaneous fusion of the cervical and lumbar spine may be a viable option for appropriate candidates. Purpose: We sought to investigate the outcomes of staged vs simultaneous cervical and lumbar fusions in terms of differences in postoperative complications and resource use. Methods: We performed a retrospective cohort study using claims data from the 2006 to 2020 all-payer Premier Health Database. Data were extracted for patients who underwent both a cervical and a lumbar fusion procedure either simultaneously (same hospitalization) or staged (within 1 year). Multivariable regression models measured the association between simultaneous or staged procedures and combined complications (including venous thromboembolism, infection, acute renal failure, or vascular/pulmonary/gastrointestinal complications), intensive care unit (ICU) admission, and prolonged length of stay. We report odds ratios (ORs) and 95% confidence intervals (CI). Results: Overall, 560 (5.2%) and 10 187 (94.8%) of total 10 747 cervical and lumbar fusion procedures were performed simultaneously and staged, respectively. When comparing outcomes after simultaneous procedures to those after staged procedures (for which outcomes from the cervical and lumbar procedures were pooled), simultaneous procedures were associated with higher rates of ICU admission and longer hospital stays, but there were no differences in rates of combined complications. Conclusion: Our retrospective, nationwide database study found that simultaneous cervical and lumbar fusion is relatively rare and its rates of complications do not differ meaningfully from those of staged procedures. However, we found an association between simultaneous cervical and lumbar fusion and higher rates of ICU admission and prolonged length of stay. Further study is warranted.

Cardiovascular Complications in Patients with Heart Failure and COVID-19: CARDIO COVID 19-20 Registry.

Since early 2020, different studies have shown an increased prevalence of COVID-19 and poorer prognosis in older adults with cardiovascular comorbidities. This study aimed to assess the impact of heart failure (HF) on cardiovascular complications, intensive care unit (ICU) admissions, and in-hospital mortality in patients hospitalized with COVID-19. The CARDIO COVID 19-20 registry includes 3260 hospitalized patients with a COVID-19 serological diagnosis between May 2020 and June 2021 from Latin American countries. A history of HF was identified in 182 patients (5.6%). In patients with and without previous HF, the incidence of supraventricular arrhythmia was 16.5% vs. 6.3%, respectively (p = 0.001), and that of acute coronary syndrome was 7.1% vs. 2.7%, respectively (p = 0.001). Patients with a history of HF had higher rates of ICU admission (61.5% vs. 53.1%, respectively; p = 0.031) and in-hospital mortality (41.8% vs. 24.5%, respectively; p = 0.001) than patients without HF. Cardiovascular mortality at discharge (42.1% vs. 18.5%, respectively; p < 0.001) and at 30 days post-discharge (66.7% vs. 18.0%, respectively) was higher for patients with a history of HF than for patients without HF. In patients hospitalized with COVID-19, previous history of HF was associated with a more severe cardiovascular profile, with increased risk of cardiovascular complications, and poor in-hospital and 30-day outcomes.

Drowning in Children and Predictive Parameters: A 15-Year Multicenter Retrospective Analysis.

Drowning is a serious and underestimated public health problem, with the highest morbidity and mortality reported among children. Data regarding pediatric outcomes of drowning are often inadequate, and data collection is poorly standardized among centers. This study aims to provide an overview of a drowning pediatric population in pediatric emergency department, focusing on its main characteristics and management and evaluating prognostic factors. This is a retrospective multicenter study involving eight Italian Pediatric Emergency Departments. Data about patients between 0 to 16 years of age who drowned between 2006 and 2021 were collected and analyzed according to the Utstein-style guidelines for drowning. One hundred thirty-five patients (60.9% males, median age at the event 5; interquartile range, 3-10) were recruited and only those with known outcome were retained for the analysis (133). Nearly 10% had a preexisting medical conditions with epilepsy being the most common comorbidity. One third were hospitalized in the intensive care unit (ICU) and younger males had a higher rate of ICU admission than female peers. Thirty-five patients (26.3%) were hospitalized in a medical ward while 19 (14.3%) were discharged from the emergency department and 11 (8.3%) were discharged after a brief medical observation less than 24 hours. Six patients died (4.5%). Medium stay in the ED was approximately 40 hours. No difference in terms of ICU admission was found between cardiopulmonary resuscitation performed by bystanders or trained medical personnel (P = 0.388 vs 0.390). This study offers several perspectives on ED victims who drowned. One of the major finding is that no difference in outcomes was seen in patients who received cardiopulmonary resuscitation performed by bystanders or medical services, highlighting the importance of a prompt intervention.

The course of infection with the Delta variant of COVID-19 in pregnancy: Analysis of clinical, laboratory, and neonatal outcomes.

This study aims to examine the effects of infection with the Delta variant of COVID-19 on the clinical course, laboratory parameters, and neonatal outcomes in pregnant women. A total of 96 pregnant women who tested positive for the Delta variant of COVID-19 were retrospectively examined. The pregnant women were divided into three groups as follows: asymptomatic, non-severe, and severe. Age, obstetric history, symptoms and findings, blood tests, medication and vaccination history, clinical course, and perinatal outcomes of pregnant women were analyzed. Pregnant women who tested positive for the Delta variant of COVID-19 had an ICU admission rate of 9.4% and a mortality rate of 5.2%. Pregnant women in the severe disease group had significantly higher rates of preterm birth and cesarean section compared with the non-severe and asymptomatic group. Pregnant women in the severe group had high c-reactive protein (CRP) levels at the time of admission. White blood cell (WBC) and procalcitonin levels increased in clinical follow-up in pregnant women in the severe group. The Delta variant of COVID-19 was found to increase mortality rates in pregnant women compared to pre-Delta variants of COVID-19. In pregnant women infected with the Delta variant of COVID-19, advanced gestational age at diagnosis, high CRP, WBC, and procalcitonin levels were significantly correlated with poor prognosis. Pregnant women infected with the Delta variant of COVID-19 had an increased risk for preterm delivery and cesarean section in the presence of severe disease. Although newborns of women with severe disease were found to have significantly higher rates of ICU admission, there was no significant difference in neonatal mortality rates. We recommend close monitoring of CRP, WBC, and procalcitonin levels in addition to symptoms in pregnant women infected with the Delta variant of COVID-19 in the third trimester.

Risks of organ failures and deaths associated with young-onset dementia after hospitalizations for motor vehicle crash injuries: a nationwide population-based retrospective cohort study

Patients with dementia are at increased risks of adverse consequences associated with motor vehicle crash injury (MVCI). However, studies of the association for patients with young-onset dementia (YOD) are limited. Therefore, we aim to investigate whether YOD was associated with adverse outcomes after hospitalization for MVCI. In this retrospective cohort study, we identified 2052 MVCI patients with YOD (aged 40–64 years) between 2006 and 2015 and included 10 260 matched MVCI patients without YOD (matching ratio: 1:5) from Taiwan’s National Health Insurance Research Database and the Taiwan Police-Reported Traffic Accident Registry. We evaluated the intensive care unit (ICU) admission, organ failure, in-hospital and 30-day mortalities, length of hospital stay, and hospital costs. Compared with participants without dementia, patients with YOD had higher rates of ICU admission (34.31% vs. 20.89%) and respiratory failure (6.04% vs. 2.94%), with a covariate-adjusted odds ratio of 1.50 (95% CI 1.33–1.70) and 1.63 (95% CI 1.24–2.13), respectively. The patients also exhibited higher in-hospital mortality (4.73% vs. 3.12%) and 30-day mortality (5.12% vs. 3.34%) than their non-YOD counterparts, but the risk ratio was not significant after adjusting for transport mode. Moreover, the log means of hospital stay and cost were higher among patients with YOD (0.09 days; 95% CI 0.04–0.14 and NT$0.17; 95% CI 0.11–0.23, respectively). This cohort study determined that YOD may be adversely associated with hospital outcomes among MVCI patients. However, the association between YOD and mortality risk may depend on transport mode.

Validation of the Rome proposal for severity of acute exacerbation of chronic obstructive pulmonary disease.

The Rome proposal provides an objective assessment tool for severity of acute exacerbation of chronic obstructive pulmonary disease (AE-COPD) but requires validation. We aimed to evaluate the predictive performance of the Rome proposal in patients with AE-COPD. This observational study assessed the patients who visited the emergency room (ER) or were hospitalized due to AE-COPD between January 2010 and December 2020. We compared the performance of the Rome Proposal with that of the DECAF score or GesEPOC 2021 criteria in predicting intensive care unit (ICU) admission, need for non-invasive ventilation (NIV) or invasive mechanical ventilation (IMV), and in-hospital mortality. A total of 740 events of ER visit or hospitalization due to AE-COPD were reviewed and classified into mild (30.9%), moderate (58.6%), or severe (10.4%) group according to the Rome proposal. The severe group had a higher rate of ICU admission, required more NIV or IMV, and had a higher in-hospital mortality than the mild and moderate groups. The predictive performance of the Rome proposal was significantly better for ICU admission [area under the receiver operating characteristic curve (AU-ROC) = 0.850 versus 0.736, p = 0.004] and need for NIV or IMV (AU-ROC = 0.870 versus 0.770, p = 0.004) than that of the GesEPOC 2021 criteria but better than that of the DECAF score only in female patients. There was no significant difference in predicting the in-hospital mortality between the Rome proposal and DECAF score or GesEPOC 2021 criteria. External validation of the Rome Proposal in Korean patients demonstrated excellent performance for ICU admission and need for NIV or IMV and an acceptable performance for in-hospital mortality.

Association between body-mass index, patient characteristics, and obesity-related comorbidities among COVID-19 patients: A prospective cohort study

ObjectiveObesity is a major risk factor for adverse outcomes after COVID-19 infection. However, it is unknown if the worse outcomes are due to the confounding effect of demographic and obesity-related comorbidities. The study objective is to analyze associations between body mass index, patient characteristics, obesity-related comorbidity, and clinical outcomes in COVID-19 patients. MethodsIn this prospective cohort study, we chose patient records between March 1st, 2020, and December 1st, 2022, in a large tertiary care center in southeast Wisconsin in the United States. Patients over the age of 18 who tested positive were included in the study. Clinical outcomes included hospitalization, intensive care unit (ICU) admission, mechanical ventilation, and mortality rates. We examined the characteristics of patients who had positive clinical outcomes. We created unadjusted logistic regression models, sequentially adjusting for demographic and comorbidity variables, to assess the independent associations between BMI, patient characteristics, obesity-related comorbidities, and clinical outcomes. ResultsFrom a record of 1.67 million inpatients and outpatients at Froedtert Health Center, 55,299 (BMI: 30.5 ± 7.4 kg/m2, 62.5 % female) tested COVID-19 positive during the study period. 17,580 (31.8 %) patients were admitted to hospitals, and of hospitalized patients required ICU admission. 1038 (36.3 %) required mechanical ventilation, and 462 (44.5 %) died after a positive test for COVID-19. We found female patients show a higher hospitalization rate, while male patients have a higher rate of ICU admission, mechanical ventilation, and mortality. Obesity-related comorbidities are associated with worse outcomes compared to simple obesity without comorbidities. In logistic regression models, we found four similar V-shaped associations between BMI and four clinical outcomes. Patients with a BMI of 25 kg/m2 are at the lowest risk for clinical outcomes. Patients with a BMI lower than 18 kg/m2 or higher than 30 kg/m2 are associated with a higher risk of hospitalization, ICU, mechanical ventilation, and death. After adjusting the model for demographic factors and hypertension and diabetes as two common comorbidities, we found that demographic factors do not significantly increase the risk. Obesity alone does not significantly increase the risk of severe clinical outcomes. Obesity-related comorbidities, on the other hand, resulted in a significantly higher risk of outcomes. ConclusionObesity alone does not increase the risk of worse clinical outcomes after COVID-19 infection. It may suggest that the worse clinical outcomes of patients with obesity are mediated via hypertension and type 2 diabetes. Patients with obesity and comorbidities have a higher risk of poor outcomes. Obesity-related comorbidities, including hypertension and diabetes, are independently associated with poorer clinical outcomes among COVID-19 patients. At a BMI of more than 30 kg/m2 or less than 18 kg/m2, we found an increase in the risk of severe COVID-19 outcomes leading to hospitalization, ICU, mechanical ventilation, and death. The increased risk of severe outcomes is not attributed to patient characteristics but can be attributed to hypertension and diabetes.

Epidemiological Features, Risk Factors, and Disease Burden of Respiratory Viruses among Hospitalized Children with Acute Respiratory Tract Infections in Xiamen, China.

Well-established surveillance and monitoring systems for respiratory viruses need to be improved, and epidemiological data on respiratory viruses in China are scarce. This study aimed to investigate the epidemiological characteristics of respiratory viruses among hospitalized children aged ≤2 years with acute respiratory tract infections (ARTIs) in Xiamen, China, from October 2014 to September 2017. The clinical records of 7,248 children hospitalized for ARTIs were retrospectively analyzed. Respiratory syncytial virus (RSV) (22.3%) was the most common virus among hospitalized children aged ≤2 years, followed by parainfluenza (5.0%), adenovirus (3.5%), and influenza (1.7%). RSV-infected children had a higher disease burden, including a higher intensive care unit (ICU) admission rate (12.7%) and higher hospital charges ($635.36). Particularly, infants aged <6 months had the highest risk of RSV infection (odds ratio = 2.4; 95% CI, 1.9-2.9) and a higher ICU admission rate (12.1% vs. 4.5%, 4.6%) and hospital cost ($923.3 vs. $785.5, $811.7) than the other age groups. Therefore, infants aged 0-6 months, particularly premature infants and children with congenital diseases, should receive more attention. There is an urgent need to develop effective immunization strategies to protect these infants during the first 6 months of life and in the RSV season.

Racial and Socioeconomic Differences in Heart Failure Hospitalizations and Telemedicine Follow-up During the COVID-19 Pandemic: Retrospective Cohort Study.

Low rates of heart failure (HF) hospitalizations were observed during the 2020 peak of the COVID-19 pandemic. Additionally, posthospitalization follow-up transitioned to a predominantly telemedicine model. It is unknown whether the shift to telemedicine impacted disparities in posthospitalization follow-up or HF readmissions. The aim of this paper is to determine whether the shift to telemedicine impacted racial and ethnic as well as socioeconomic disparities in acute decompensated heart failure (ADHF) follow-up and HF readmissions. We additionally sought to investigate the impact of the COVID-19 pandemic on the severity of ADHF hospitalizations. This was a retrospective cohort study of HF admissions across 8 participating hospitals during the initial peak of the COVID-19 pandemic (March 15 to June 1, 2020), compared to the same time frame in 2019. Patients were stratified by race, ethnicity, and median neighborhood income. Hospital and intensive care unit (ICU) admission rates, inpatient mortality, 7-day follow-up, and 30-day readmissions were assessed. From March 15, 2019, to June 1, 2020, there were 1162 hospitalizations for ADHF included in the study. There were significantly fewer admissions for ADHF in 2020, compared with 2019 (442 vs 720; P<.001). Patients in 2020 had higher rates of ICU admission, compared with 2019 (15.8% vs 11.1%; P=.02). This trend was seen across all subgroups and was significant for patients from the highest income quartile (17.89% vs 10.99%; P=.02). While there was a trend toward higher inpatient mortality in 2020 versus 2019 (4.3% vs 2.8%; P=.17), no difference was seen among different racial and socioeconomic groups. Telemedicine comprised 81.6% of 7-day follow-up in 2020, with improvement in 7-day follow-up rates (40.5% vs 29.6%; P<.001). Inequities in 7-day follow-up for patients from non-Hispanic Black racial backgrounds compared to those from non-Hispanic White backgrounds decreased during the pandemic. Additionally, those with telemedicine follow-up were less likely to be readmitted in 30 days when compared to no follow-up (13.8% vs 22.4%; P=.03). There were no major differences in HF ICU admissions or inpatient mortality for different racial and socioeconomic groups during the COVID-19 pandemic. Inequalities in 7-day follow-up were reduced with the advent of telemedicine and decreased 30-day readmission rates for those who had telemedicine follow-up.

Lost in Translation: Evaluation of Subcutaneous Interferon-β Treatment for SARS-CoV-2 Infection in Real Life.

Despite in vitro activity of interferon-β (IFN-β) against SARS-CoV-2 infection, its clinical efficacy remains controversial. We evaluated the impact of IFN-β treatment in a cohort of 3590 patients hospitalized with COVID-19 during March−April 2020. The primary endpoint was a composed variable of admission to intensive care unit (ICU)/death. Overall, 153 patients (4%) received IFN-β. They were significantly more severely ill, with a worse clinical and analytical situation, explaining a higher ICU admission (30% vs. 17%; p < 0.01), and a shorter time to the composed variable. In a Cox regression analysis, older age, lymphopenia, renal failure, or increased neutrophil-to-lymphocyte ratio were associated with a greater hazard ratio (HR) of admission at ICU/death. Notably, the HR of IFN-β for the outcome variable was no longer significant after adjustment (HR, 1.03; 95% CI, 0.82−1.30), and different sensitivity analysis (early IFN use, ICU admission) showed no changes in the estimates. A propensity score matching analysis showed no association of IFN-β therapy and outcome. In conclusion, in this large cohort of hospitalized COVID-19 patients, IFN-β was used mainly in patients with advanced disease, reflecting an important bias of selection. After adjusting by severity, IFN-β was not associated with a higher rate of ICU admission or mortality.

Measures of Structural Racism Predict ICU Admission Following Intensive Chemotherapy for AML

INTRODUCTION: Recent observational studies have revealed that real-world complications of intensive chemotherapy for frontline treatment of acute myeloid leukemia (AML) far exceed those reported in clinical trials. A 2017 analysis of over 40,000 AML patients found that 26% of patients who received induction chemotherapy were admitted to the intensive care unit (ICU), with increased mortality for non-white patients (Halpern, JAMA Oncology 2016). In a newly created Chicago AML registry (Abraham, Blood 2022), higher ICU admission rate was noted following induction chemotherapy for non-white patients. The current study aims to i) describe treatment complications based on race/ethnicity and ii) examine structural racism (SR) measures as risk factors for ICU admission following intensive chemotherapy in a diverse real-world patient population. METHODS: Using the Chicago AML registry, we compared ethnoracial differences in treatment complications including infections, thrombosis, renal or liver dysfunction (defined as peak creatinine >1.5 g/dL or peak bilirubin >1.2 mg/dL), respiratory failure requiring ventilatory support and hemodynamic instability needing pressor support. We then examined associations of race/ethnicity and previously published measures of census tract disadvantage, affluence, and segregation (referred to as SR measures) with ICU admission. These structural barriers were examined alongside known predictors of treatment mortality including disease characteristics and comorbidities. Additional outcomes included duration of ICU stay and mortality. RESULTS: In this cohort of 573 patients who underwent intensive induction chemotherapy for AML, 30-day complications differed based on race/ethnicity. Renal dysfunction was highest in non-Hispanic black (NHB) patients with an incidence of 27.8% with 6% initiating dialysis compared to 17.6% of non-Hispanic white (NHW) and 11.3% of Hispanic patients with 2% needing dialysis. Hepatotoxicity was highest in Hispanic patients (64%) vs. NHB (51%) and NHW (47%). Infectious complications were highest in NHB with microbiologically documented infections in 50.6% compared to 39.7% in NHW and 32.6% in Hispanic. Venous thrombosis occurred in 14.5% of NHB patients, compared to 14.7% of NHW and 13.3% Hispanic patients. In total, 141 (24.6%) patients required ICU admission during intensive induction with rates differing significantly by race and ethnicity (p = 0.014). Average length of stay in the ICU was 7.8 days for NHB patients, 6.7 days for NHW and 6.0 days for Hispanics. Due to low 30-day mortality, we were unable to detect differences between ethnoracial groups. Mechanical ventilation was utilized in 32% of NHB compared to 26% of NHW and 20% of Hispanic patients admitted to the ICU. Vasopressor were required in 31% of NHB patients vs. 27% of NHW patients. Predictors of ICU admission in our dataset included non-white race, unmarried status, living in a neighborhood with lower % of NHW residents, and WBC > 50,000/µL at diagnosis. Additional census tract variables including higher disadvantage and lower affluence conferred nonsignificant risk. Interestingly, comorbidities, ELN Score and baseline creatinine > 1.5 g/dL were not predictors of ICU admission. CONCLUSIONS: In a real-world population of AML patients, we show variation in the spectrum of treatment complications based on race/ethnicity. Moreover, with detailed individual and neighborhood socioeconomic position (SEP) data, measures of SR predicted ICU admission following induction chemotherapy. Other significant predictors include marital status - an individual measure of SEP, and hyperleukocytosis, which may indicate delay in medical presentation. High comorbidity index did not predict increased rate of ICU admission similar to prior studies (Tawfik, J Geriatr Oncol, 2016), while renal dysfunction was a non-significant predictor. Collectively our results suggest that there is a need to incorporate individual and neighborhood SR measures to identify patients at risk of clinical decline when stressed with intensive therapies. An algorithmic approach to identify 'high risk’ patients based on clinical/molecular and structural factors could prompt more detailed assessment of fitness prior to initiation of chemotherapy and directly influence leukemia outcome disparities.

Timing of endoscopic retrograde cholangiopancreatography in the treatment of acute cholangitis of different severity.

BACKGROUNDThe optimal timing of endoscopic retrograde cholangiopancreatography (ERCP) in acute cholangitis (AC) is uncertain, especially in patients with AC of varying severity.AIMTo report whether the timing of ERCP is associated with outcomes in AC patients with different severities.METHODSAccording to the 2018 Tokyo guidelines, 683 patients who met the definite diagnostic criteria for AC were retrospectively identified. The results were first compared between patients receiving ERCP ≤ 24 h and > 24 h and then between patients receiving ERCP ≤ 48 h and > 48 h. Subgroup analyses were performed in patients with grade I, II or III AC. The primary outcome was 30-d mortality. Secondary outcomes were intensive care unit (ICU) admission rate, length of hospital stay (LOHS) and 30-d readmission rate.RESULTSTaking 24 h as the critical value, compared with ERCP > 24 h, malignant biliary obstruction as a cause of AC was significantly less common in the ERCP ≤ 24 h group (5.2% vs 11.5%). The proportion of cardiovascular dysfunction (11.2% vs 2.6%), respiratory dysfunction (14.2% vs 5.3%), and ICU admission (11.2% vs 4%) in the ERCP ≤ 24 h group was significantly higher, while the LOHS was significantly shorter (median, 6 d vs 7 d). Stratified by the severity of AC, higher ICU admission was only observed in grade III AC and shorter LOHS was only observed in grade I and II AC. There were no significant differences in 30-d mortality between groups, either in the overall population or in patients with grade I, II or III AC. With 48 h as the critical value, compared with ERCP > 48 h, the proportion of choledocholithiasis as the cause of AC was significantly higher in the ERCP ≤ 48 h group (81.5% vs 68.3%). The ERCP ≤ 48 h group had significantly lower 30-d mortality (0 vs 1.9%) and shorter LOHS (6 d vs 8 d). Stratified by AC severity, lower 30-d mortality (0 vs 6.1%) and higher ICU admission rates (22.2% vs 10.2%) were only observed in grade III AC, and shorter LOHS was only observed in grade I and II AC. In the multivariate analysis, cardiovascular dysfunction and time to ERCP were two independent factors associated with 30-d mortality.CONCLUSIONERCP ≤ 48 h conferred a survival benefit in patients with grade III AC. Early ERCP shortened the LOHS in patients with grade I and II AC.

Patterns of Head and Neck Injuries in Urban India: A Multicenter Study.

ObjectiveThe pattern of head and neck injuries has been well studied in high-income countries, but the data are limited in low- and middle-income countries, which are disproportionately affected by trauma. We examined a prospective multicenter database to describe patterns and outcomes of head and neck injuries in urban India.Study DesignRetrospective review of trauma registry.SettingFour tertiary public hospitals in Mumbai, Delhi, Kolkata.MethodsWe identified patients with isolated head and neck injuries using International Classification of Diseases, 10th Revision (ICD-10) codes and excluded those with traumatic brain and/or ophthalmic injuries and injuries in other body regions.ResultsOur cohort included 171 patients. Most were males (80.7%) and adults aged 18 to 55 years (60.2%). Falls (36.8%) and road traffic accidents (36.3%) were the 2 predominant mechanisms of injury. Overall, 35.7% required intensive care unit (ICU) admission, and 11.7% died. More than 20% of patients were diagnosed with “unspecified injury of neck.” Those with the diagnosis had a higher ICU admission rate (51.4% vs 31.3%, P = .025) and mortality rate (27.0% vs 7.5%, P = .001) than those without the diagnosis.ConclusionIsolated head and neck injuries are not highly prevalent among Indian trauma patients admitted to urban tertiary hospitals but are associated with high mortality. Over a fifth of patients were diagnosed with “unspecified injury of neck,” which is associated with more severe clinical outcomes. Exactly what this diagnosis entails and encompasses remains unclear.

Racial and Ethnic Disparities in Hospitalization and Clinical Outcomes Among Patients with COVID-19

IntroductionThe recent spread of coronavirus disease 2019 (COVID-19) has disproportionately impacted racial and ethnic minority groups; however, the impact of healthcare utilization on outcome disparities remains unexplored. Our study examines racial and ethnic disparities in hospitalization, medication usage, intensive care unit (ICU) admission and in-hospital mortality for COVID-19 patients.MethodsIn this retrospective cohort study, we analyzed data for adult patients within an integrated healthcare system in New York City between February 28–August 28, 2020, who had a lab-confirmed COVID-19 diagnosis. Primary outcome was likelihood of inpatient admission. Secondary outcomes were differences in medication administration, ICU admission, and in-hospital mortality.ResultsOf 4717 adult patients evaluated in the emergency department (ED), 3219 (68.2%) were admitted to an inpatient setting. Black patients were the largest group (29.1%), followed by Hispanic/Latinx (29.0%), White (22.9%), Asian (3.86%), and patients who reported “other” race-ethnicity (19.0%). After adjusting for demographic, clinical factors, time, and hospital site, Hispanic/Latinx patients had a significantly lower adjusted rate of admission compared to White patients (odds ratio [OR] 0.51; 95% confidence interval [CI] 0.34–0.76). Black (OR 0.60; 95% CI 0.43–0.84) and Asian patients (OR 0.47; 95% CI 0.25 – 0.89) were less likely to be admitted to the ICU. We observed higher rates of ICU admission (OR 2.96; 95% CI 1.43–6.15, and OR 1.83; 95% CI 1.26–2.65) and in-hospital mortality (OR 4.38; 95% CI 2.66–7.24; and OR 2.96; 95% CI 2.12–4.14) at two community-based academic affiliate sites relative to the primary academic site.ConclusionNon-White patients accounted for a disproportionate share of COVID-19 patients seeking care in the ED but were less likely to be admitted. Hospitals serving the highest proportion of minority patients experienced the worst outcomes, even within an integrated health system with shared resources. Limited capacity during the COVID-19 pandemic likely exacerbated pre-existing health disparities across racial and ethnic minority groups.

Comparing Outcomes between Major Trauma Patients Transferred from a Different Hospital and Patients Transported Directly to Trauma Centers: A Retrospective Analysis with Propensity Score Matching Analysis.

This study aimed to explore differences in outcomes between these major trauma patients who were transferred and those directly transported to trauma centers. The medical information and outcome of 5,341 major trauma patients with an injury severity score (ISS) ≥ 16 who were hospitalized for treatment between January 1, 2009, and December 31, 2019, were collected from the Trauma Registry System of the hospital. There were 2,386 patients who were transferred (transfer group) and 2,955 patients transported directly to trauma centers first (direct group). Regarding the outcomes, there was no significant difference in the mortality rate between patients in the transfer group and the direct group (11.1% vs. 10.5%, respectively, p=0.527). However, the patients in the transfer group had a longer hospital stay (16.8 days vs. 14.3 days, respectively, p < 0.001) and higher incidence of intensive care unit (ICU) admission (74.9% vs. 70.5%, respectively, p < 0.001) than those patients in the direct group. Similar results were observed in the selected 2,139 pairs of propensity score-matched patient populations, who did not present with significant differences in sex, age, comorbidities, trauma mechanisms, and ISS. This study revealed no significant difference in the mortality rate between the two groups of major trauma patients. However, the transferred patients had significantly longer hospital stays and higher rates of ICU admission than patients directly transported to trauma centers.

Obesity Impact on SARS-CoV-2 Infection: Pros and Cons "Obesity Paradox"-A Systematic Review.

Background: During the last years, the COVID-19 pandemic meets the pandemic generated by obesity, raising many questions regarding the outcomes of those with severe forms of infection. Methods: The present systematic review summarises and analyses the data providing evidence for or against the “obesity-paradox” in COVID-19 patients. After applying the inclusion and exclusion criteria, 23 studies were included. We also analysed the presumably underlying basic mechanisms. Results: The patients with a body mass index (BMI) of 30–40 kg/m2 presented severe symptoms that led to intensive care unit (ICU) admission but not increased death rate. Those with a higher degree of obesity, with a BMI higher than 40 kg/m2, led to a rise in the death rate, particularly in young patients. Obesity was associated with a higher rate of ICU admission but was not determined as an independent predictor of increased mortality. In contrast, some studies suggest a strong association between obesity or morbid obesity and the risk of death. Conclusions: The existence of “obesity-paradox” cannot be stated; our study presents obesity as a critical risk factor in the evolution of COVID-19.

Association Between Intensive Care Unit Admission Practices and Outcomes in Patients with Isolated Traumatic Subarachnoid Hemorrhage: A Nationwide Inpatient Database Analysis in Japan.

Patients with traumatic brain injury associated with intracranial hemorrhage are commonly admitted to the intensive care unit (ICU); however, the need for ICU care for patients with isolated traumatic subarachnoid hemorrhage (tSAH) remains unclear. We aimed to investigate the association between the ICU admission practices and outcomes in patients with isolated tSAH. This observational study used a nationwide administrative database in Japan. We identified patients with isolated tSAH from the Japanese Diagnostic Procedure Combination inpatient database from July 1, 2010, to March 31, 2020. The primary outcome was in-hospital mortality, whereas the secondary outcomes were neurosurgical interventions, activities of daily living at discharge, and total hospitalization cost. We performed a risk-adjusted mixed-effect regression analysis to evaluate the association between hospital-level ICU admission rates and study outcomes. The ICU admission rates were categorized into quartiles: lowest, middle-low, middle-high, and highest. Moreover, we assessed the robustness of the results with a patient-level instrumental variable analysis. Of the 61,883 patients with isolated tSAH treated at 962 hospitals, 16,898 (27.3%) patients were admitted to the ICU on the day of admission. Overall, 2465 (4.0%) patients died in the hospital, and 783 (1.3%) patients underwent neurosurgical interventions. There was no significant difference between the lowest and highest ICU admission quartile in terms of in-hospital mortality (3.7% vs. 4.3%; adjusted odds ratio 0.93; 95% confidence interval [CI] 0.78-1.10), neurosurgical interventions, and activities of daily living at discharge. However, the total hospitalization cost in the lowest ICU admission quartile was significantly lower than that in the highest quartile (US $3032 vs. $4095; adjusted difference US $560; 95% CI 33-1087). The patient-level instrumental variable analysis did not reveal a significant difference in in-hospital mortality between the patients who were admitted to the ICU and those who were not (risk difference 0.2%; 95% CI - 0.1 to 0.5). There was no significant association between the ICU admission practices and outcomes in patients with isolated tSAH, whereas higher ICU admission rates were associated with significantly higher hospitalization costs. Our results provide an opportunity for improved health care allocation in the management of patients with isolated tSAH.

Age, Sex, and Race/Ethnicity in Clinical Outcomes Among Patients Hospitalized With COVID-19, 2020.

The COVID-19 pandemic revealed the disproportionate risk of poor clinical outcomes among population subgroups. The study investigates length of stay (LOS), intensive care unit (ICU) admission, and in-hospital death across age, sex, and race among patients hospitalized with COVID-19. A pooled cross-sectional study analyzed hospital discharge data of state-licensed hospitals in Texas from April to December 2020. Of 98,879 patients, males accounted for 52.3%. The age distribution was 31.9% for the 65–79 age group, 29.6% for those aged 50–64, and 16.3% for those older than 79. Whites constituted the largest proportion (42.6%), followed by Hispanics (36.2%) and Blacks (13.1%). Higher in-hospital death rates were found among patients aged 80 and over (Adjusted Risk Ratio (aRR) 1.12, 95%CI 1.11–1.13) and patients aged 65–79 (aRR 1.08, 95%CI 1.07–1.09) compared to patients aged 19 and below. Hispanics (aRR 1.03, 95%CI 1.02–1.03) and other minorities (aRR 1.02, 95%CI 1.02–1.03) exhibited higher in-hospital death rates than whites, and these patients also had longer LOS and higher ICU admission rates. Patients aged 65–79, 50–64, and 80 and over all had longer hospital stays and higher ICU admission rates. Males experienced poor health outcomes in all assessed outcomes. Findings showed that disparities in clinical outcomes among population subgroups existed and remained throughout 2020. While the nation has to continue practicing public health measures to minimize the harm caused by the novel virus, serious consideration must be given to improving the health of marginalized populations during and beyond the pandemic.

Use of an extended KDIGO definition to diagnose acute kidney injury in patients with COVID-19: A multinational study using the ISARIC-WHO clinical characterisation protocol.

Acute kidney injury (AKI) is one of the most common and significant problems in patients with Coronavirus Disease 2019 (COVID-19). However, little is known about the incidence and impact of AKI occurring in the community or early in the hospital admission. The traditional Kidney Disease Improving Global Outcomes (KDIGO) definition can fail to identify patients for whom hospitalisation coincides with recovery of AKI as manifested by a decrease in serum creatinine (sCr). We hypothesised that an extended KDIGO (eKDIGO) definition, adapted from the International Society of Nephrology (ISN) 0by25 studies, would identify more cases of AKI in patients with COVID-19 and that these may correspond to community-acquired AKI (CA-AKI) with similarly poor outcomes as previously reported in this population. All individuals recruited using the International Severe Acute Respiratory and Emerging Infection Consortium (ISARIC)-World Health Organization (WHO) Clinical Characterisation Protocol (CCP) and admitted to 1,609 hospitals in 54 countries with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection from February 15, 2020 to February 1, 2021 were included in the study. Data were collected and analysed for the duration of a patient's admission. Incidence, staging, and timing of AKI were evaluated using a traditional and eKDIGO definition, which incorporated a commensurate decrease in sCr. Patients within eKDIGO diagnosed with AKI by a decrease in sCr were labelled as deKDIGO. Clinical characteristics and outcomes-intensive care unit (ICU) admission, invasive mechanical ventilation, and in-hospital death-were compared for all 3 groups of patients. The relationship between eKDIGO AKI and in-hospital death was assessed using survival curves and logistic regression, adjusting for disease severity and AKI susceptibility. A total of 75,670 patients were included in the final analysis cohort. Median length of admission was 12 days (interquartile range [IQR] 7, 20). There were twice as many patients with AKI identified by eKDIGO than KDIGO (31.7% versus 16.8%). Those in the eKDIGO group had a greater proportion of stage 1 AKI (58% versus 36% in KDIGO patients). Peak AKI occurred early in the admission more frequently among eKDIGO than KDIGO patients. Compared to those without AKI, patients in the eKDIGO group had worse renal function on admission, more in-hospital complications, higher rates of ICU admission (54% versus 23%) invasive ventilation (45% versus 15%), and increased mortality (38% versus 19%). Patients in the eKDIGO group had a higher risk of in-hospital death than those without AKI (adjusted odds ratio: 1.78, 95% confidence interval: 1.71 to 1.80, p-value < 0.001). Mortality and rate of ICU admission were lower among deKDIGO than KDIGO patients (25% versus 50% death and 35% versus 70% ICU admission) but significantly higher when compared to patients with no AKI (25% versus 19% death and 35% versus 23% ICU admission) (all p-values <5 × 10-5). Limitations include ad hoc sCr sampling, exclusion of patients with less than two sCr measurements, and limited availability of sCr measurements prior to initiation of acute dialysis. An extended KDIGO definition of AKI resulted in a significantly higher detection rate in this population. These additional cases of AKI occurred early in the hospital admission and were associated with worse outcomes compared to patients without AKI.

The Effects of COVID-19 on Patients with Acute Ischemic and Hemorrhagic Stroke

ObjectiveThe objective of this study was to evaluate how COVID-19 affects patients with acute ischemic or hemorrhagic stroke outcome. Materials and methodsThis retrospective study was performed on adult patients (> 18 years old) with stroke (ischemic or hemorrhagic) who were admitted to hospital with or without COVID-19. The primary outcome was stroke-related disability, which was measured by mRS at baseline and discharge. Hospital duration, intensive care unit (ICU) admission, and mortality were considered the secondary outcomes. ResultsFrom February 2019 until August 2020, we recruited and analyzed 151 patients, 42 of whom had COVID-19 based on RT-PCR tests or lung CT scan findings. COVID-19 positive patients had higher baseline and final mRS scores than the control group (4.46 ± 0.67 vs 4.79 ± 0.61, P: 0.001, 3.83 ± 1.22 vs 4.46 ± 0.67, P: 0.001). Moreover, stroke patients with COVID-19 experienced a more severe disease and required a higher rate of ICU admission (17 vs 0, P:0.001) and longer hospitalization compared to those without COVID-19 (8.50 ± 7.86 vs 7.5 ± 11.20, P: 0.021). Also, mortality was higher in the COVID-19 group (19 vs 13, P:0.001). There was not any significant differences between the two groups in terms of the involvement of cerebral arteries and type of stroke. Male sex, COVID-19, and ICU admission were the main independent risk factors for death. ConclusionThe results of the study showed stroke patients (ischemic or hemorrhagic) with COVID-19 can have more disabilities and incur more hospital complications and mortality than non-COVID-19 patients.
