RESUMEN
Background: Although palliative medicine (PM) is more commonly being integrated into the intensive care unit (ICU), research on racial disparities in this area is lacking. Our objectives were to (a) identify racial disparities in utilization of PM consultation for patients who received ICU care and (b) determine if there were differences in the use of code status or PM consultation over time based on race. Materials and Methods: Retrospective analysis of 571 patients, 18 years and above, at a tertiary care institution who received ICU care and died during their hospital stay. We analyzed two timeframes, 2008-2009 and 2018-2019. Univariate analysis was utilized to evaluate baseline characteristics. A multivariate logistic regression model and interaction P values were employed to assess for differential use of PM consultation, do not resuscitate (DNR) orders, and comfort care (CC) orders between races in aggregate and for changes over time. Results: There was a notable increase in Black/African-American (AA) (54% to 61%) and Hispanic/Latino (2% to 3%) patients over time in our population. Compared to White patients, we found no differences between PM consultation and CC orders. There was a lower probability of DNR orders for Black/AA (adjusted odds ratio [aOR] 0.569; P = .049; confidence interval [CI]: 0.324-0.997) and other/unknown/multiracial patients (aOR: 0.389; P = .273; CI: 0.169-0.900). Comparing our earlier time period to the later time period, we found an increased usage of PM for all patients. Interaction P values suggest there were no differences between races regarding PM, DNR, and CC orders. Conclusions: PM use has increased over time at our institution. Contrary to the previous literature, there were no differences in the frequency of utilization of PM consultation between races. Further analysis to evaluate the usage of PM in the ICU setting in varying populations and geographic locations is warranted.

BACKGROUND: During cardiopulmonary resuscitation, intravenous thrombolytics are commonly used for patients whose underlying etiology of cardiac arrest is presumed to be related to pulmonary embolism (PE). METHODS: We performed a systematic review and meta-analysis of the existing literature that focused on the use of thrombolytics for cardiac arrest due to presumed or confirmed PE. Outcomes of interest were return of spontaneous circulation (ROSC), survival to hospital discharge, neurologically-intact survival, and bleeding complications. RESULTS: Thirteen studies with a total of 803 patients were included in this review. Most studies included were single-armed and retrospective. Thrombolytic agent and dose were heterogeneous between studies. Among those with control groups, intravenous thrombolysis was associated with higher rates of ROSC (OR 2.55, 95% CI = 1.50-4.34), but without a significant difference in survival to hospital discharge (OR 1.41, 95% CI = 0.79-2.41) or bleeding complications (OR 2.21, 0.95-5.17). CONCLUSIONS: Use of intravenous thrombolytics in cardiac arrest due to confirmed or presumed PE is associated with increased ROSC but not survival to hospital discharge or change in bleeding complications. Larger randomized studies are needed. Currently, we recommend continuing to follow existing consensus guidelines which support use of thrombolytics for this indication.

BACKGROUND: Central venous oxygen saturation (ScvO2) obtained from a central venous catheter (CVC) is often used to approximate oxygen delivery in critically ill patients. Despite their importance in administering medications and monitoring oxygen delivery, the use of CVCs can be associated with significant complications. Midline catheters are inserted via a peripheral vein above the antecubital fossa and provide a safe alternative to CVCs. This study aimed to determine the equivalence of ScvO2 and midline catheter oxygen saturation (SmO2) in critically ill patients. METHODS: This was a single-center observational study of critically ill adult patients who had concurrently placed CVCs (internal jugular and subclavian) and midline catheters as part of standard ICU care. Venous oxygen saturation and lactate levels were measured from both catheters using the Abbott point-of-care i-STAT analyzer. Demographic and ICU admission data were collected. Continuous variables were compared using the paired t-test. Pearson's correlation was used to evaluate the linear correlation between ScvO2 and SmO2. The systematic error (bias) was calculated using Bland-Altman analysis. Receiver operating characteristic curves were constructed to evaluate the sensitivities and specificities for different values of SmO2 to predict ScvO2. RESULTS: Forty-eight patients (n = 48) were enrolled in the study. The mean ScvO2 and SmO2 were 65.5% +/- 11.2% and 62.7% +/- 17.6% respectively (p = 0.1197). In the Bland-Altman analysis, the mean bias between ScvO2 and SmO2 was 2.8% +/- 12.3% with 95% limits of agreement of -21.3% to 26.9%. More than 60% of the ScvO2 and SmO2 values diverged by ≥ 5%. CONCLUSIONS: The difference between the mean SmO2 and ScvO2 was not statistically significant and the mean bias between SmO2 and ScvO2 is low. Despite this, the substantially large standard deviation and limits of agreement preclude the use of SmO2 as a direct surrogate of ScvO2.
RESUMEN
Purpose: Secondary opportunistic coinfections are a significant contributor to morbidity and mortality in intensive care unit (ICU) patients, but can be difficult to identify. Presently, new blood RNA biomarkers were tested in ICU patients to diagnose viral, bacterial, and biofilm coinfections. Methods: COVID-19 ICU patients had whole blood drawn in RNA preservative and stored at -80°C. Controls and subclinical infections were also studied. Droplet digital polymerase chain reaction (ddPCR) quantified 6 RNA biomarkers of host neutrophil activation to bacterial (DEFA1), biofilm (alkaline phosphatase [ALPL], IL8RB/CXCR2), and viral infections (IFI27, RSAD2). Viral titer in blood was measured by ddPCR for SARS-CoV2 (SCV2). Results: RNA biomarkers were elevated in ICU patients relative to controls. DEFA1 and ALPL RNA were significantly higher in severe versus incidental/moderate cases. SOFA score was correlated with white blood cell count (0.42), platelet count (-0.41), creatinine (0.38), and lactate dehydrogenase (0.31). ALPL RNA (0.59) showed the best correlation with SOFA score. IFI27 (0.52) and RSAD2 (0.38) were positively correlated with SCV2 viral titer. Overall, 57.8% of COVID-19 patients had a positive RNA biomarker for bacterial or biofilm infection. Conclusions: RNA biomarkers of host neutrophil activation indicate the presence of bacterial and biofilm coinfections in most COVID-19 patients. Recognizing coinfections may help to guide the treatment of ICU patients.
RESUMEN
OBJECTIVE: Endotoxin is a component of Gram-negative bacteria and can be measured in blood using the endotoxin activity assay (EAA). Endotoxin exposure initiates an inflammatory cascade that may contribute to organ dysfunction. Endotoxemia has been reported in previous viral pandemics and we investigated the extent of endotoxemia and its relationship to outcomes in critically ill patients with COVID-19. MATERIALS AND METHODS: We conducted a Prospective Cohort Study of 96 critically-ill COVID-19 patients admitted to the George Washington University Hospital ICU from 25 Mar-6 Jun 2020. EAA and inflammatory markers (ferritin, d dimer, IL-6, CRP) were measured on ICU admission and at the discretion of the clinical team. Clinical outcomes (mortality, LOS, need for renal replacement therapy (RRT), intubation) were measured. Statistical analysis was conducted using descriptive statistics and effect estimates with 95% confidence intervals. Comparisons were made using chi-square tests for categorical variables, and T-tests for continuous variables. RESULTS: A majority of patients (68.8%) had high EAA [≥ 0.60], levels seen in septic shock. Only 3 patients had positive bacterial cultures. EAA levels did not correlate with mortality, higher levels were associated with greater organ failure (cardiovascular, renal) and longer ICU LOS. Among 14 patients receiving RRT for severe AKI, one had EAA < 0.6 (p = 0.043). EAA levels did not directly correlate with other inflammatory markers. CONCLUSIONS: High levels of endotoxin activity were found in a majority of critically-ill COVID-19 patients admitted to the ICU and were associated with greater risk for cardiovascular and renal failure. Further investigation is needed to determine if endotoxin reducing strategies are useful in treating severe COVID-19 infection.

BACKGROUND: Thromboelastography (TEG) can guide transfusion therapy in trauma and has been associated with decreased transfusion requirements. This population differs from the medical population where the most common bleeding source is gastrointestinal hemorrhage (GIB). The utility of TEG in patients with acute GIB is not well described. We sought to assess whether the use of TEG impacts blood product utilization in patients with medical GIB. METHODS: A retrospective study looking at all adult patients admitted with a primary diagnosis of GIB to the George Washington University Intensive Care Unit (ICU) between 01/01/2017 to 12/31/2019. The primary intervention was the use of TEG to guide blood product resuscitation in addition to standard of care (TEG arm) versus standard of care alone (non-TEG arm). RESULTS: The primary outcome was the total number of blood products utilized. Patients in the TEG arm used more blood products compared to the non-TEG arm (9.10 vs 3.60, p < 0.001). There was no difference in secondary endpoints except for an increased requirement for mechanical ventilation within the TEG arm (26.2% vs 13.4%, p = 0.018). CONCLUSIONS: The use of TEG to guide resuscitation in patients with acute GIB may be associated with increased blood product utilization without any clinical benefit to patient-centered outcomes.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is associated with a prothrombotic state; leading to multiple sequelae. We sought to detect whether thromboelastography (TEG) parameters would be able to detect thromboembolic events in patients hospitalized with COVID-19. METHODS: We performed a retrospective multicenter case-control study of the Collaborative Research to Understand the Sequelae of Harm in COVID (CRUSH COVID) registry of 8 tertiary care level hospitals in the United States (US). This registry contains adult patients with COVID-19 hospitalized between March 2020 and September 2020. RESULTS: A total of 277 hospitalized COVID-19 patients were analyzed to determine whether conventional coagulation TEG parameters were associated with venous thromboembolic (VTE) and thrombotic events during hospitalization. A clotting index (CI) >3 was present in 45.8% of the population, consistent with a hypercoagulable state. Eighty-three percent of the patients had clot lysis at 30 min (LY30) = 0, consistent with fibrinolysis shutdown, with a median of 0.1%. We did not find TEG parameters (LY30 area under the receiver operating characteristic [ROC] curve [AUC] = 0.55, 95% CI: 0.44-0.65, P value = .32; alpha angle [α] AUC = 0.58, 95% CI: 0.47-0.69, P value = .17; K time AUC = 0.58, 95% CI: 0.46-0.69, P value = .67; maximum amplitude (MA) AUC = 0.54, 95% CI: 0.44-0.64, P value = .47; reaction time [R time] AUC = 0.53, 95% CI: 0.42-0.65, P value = .70) to be a good discriminator for VTE. We also did not find TEG parameters (LY30 AUC = 0.51, 95% CI: 0.42-0.60, P value = .84; R time AUC = 0.57, 95%CI: 0.48-0.67, P value .07; α AUC = 0.59, 95%CI: 0.51-0.68, P value = .02; K time AUC = 0.62, 95% CI: 0.53-0.70, P value = .07; MA AUC = 0.65, 95% CI: 0.57-0.74, P value < .01) to be a good discriminator for thrombotic events. CONCLUSIONS: In this retrospective multicenter cohort study, TEG in COVID-19 hospitalized patients may indicate a hypercoagulable state, however, its use in detecting VTE or thrombotic events is limited in this population.

BACKGROUND: Providers performing endotracheal intubation are at high risk of contracting SARS-CoV-2. The objective was to assess various demographic, exposure and institutional preparedness factors affecting intubators' comfort and fear level during COVID-19 intubations. METHODS: We conducted a cross-sectional, survey-based study during the COVID-19 pandemic from September 2020 to January 2021 at a single academic medical centre in Washington, DC, USA. Inclusion criteria were healthcare providers who had an experience in intubating patients confirmed with or suspected of COVID-19. The survey assessed various factors related to the providers' comfort with intubation and fear during COVID-19 intubations. RESULTS: A total of 329 surveys from 55 hospitals were analysed. Of the respondents, 173 (52.6%) were from emergency medicine providers. Factors that were associated with a higher comfort level of intubating patients with COVID-19 included attending physician position (adjusted OR (aOR)=2.6, 95% CI 1.4 to 4.8; p=0.003), performing more than 20 COVID-19 intubations (aOR=3.3, 95% CI 1.5 to 6.6; p=0.002), participation in an intubation team (aOR=1.6, 95% CI 1.1 to 2.7; p=0.031) and adequate levels of personal protective equipment (PPE) (aOR=4.3, 95% CI 2.0 to 8.8; p<0.0005). Compared with emergency physicians, anaesthesiology providers had higher fear levels of contracting SARS-CoV-2 during both first and subsequent SARS-CoV-2 intubations (first: OR=1.7, 95% CI 1.1 to 2.6, p=0.006; subsequent: OR=2.0, 95% CI 1.4 to3.2, p<0.0005). CONCLUSION: A higher degree of comfort in intubating patients suspected of or confirmed with COVID-19 was demonstrated in more senior physicians, members of intubation teams, providers who performed a higher number of intubations and providers who reported adequate PPE. These findings highlight potential targets for improving the experience of providers in this setting.

INTRODUCTION: Hypertonic saline is often used to treat patients with traumatic brain injury. It carries the undesired side effect of hyperchloremia, which has been linked to acute kidney injury (AKI). We sought to evaluate the relationship of hyperchloremia and AKI in this population and whether the absolute exposure to hyperchloremia, including maximal hyperchloremia and duration of hyperchloremia were associated with AKI. METHODS: A retrospective study of severe traumatic brain injury patients who received hypertonic saline at a single academic institution. Demographics, head abbreviated injury scale, development of hyperchloremia (Cl ≥ 115), duration of hyperchloremia, highest chloride level, duration of hypertonic saline use, admission GFR, and administration of nephrotoxic medications were abstracted. The outcome of interest was the association between renal function and hyperchloremia. RESULTS: A total of 123 patients were included in the study. Multivariable logistic regression analysis demonstrated that only duration of hyperchloremia (p = 0.014) and GFR on admission (p = 0.004) were independently associated with development of AKI. The number of days of hypertonic saline infusion (p = 0.79) without the persistence of hyperchloremia and highest serum chloride levels (p = 0.23) were not predictive of AKI development. DISCUSSION: In patients with traumatic brain injury, admission GFR and prolonged hyperchloremia rather than the highest chloride level or the duration of hypertonic saline infusion were associated with the development of AKI.

PURPOSE: Instructional videos of medical procedures can be a useful guide for learners, demonstrating proper and safe technique. Open publishing sites such as YouTube are readily accessible, however the content is not peer reviewed and quality of videos vary greatly. Our aim was to evaluate a learner's ability to interpret the quality of openly published content by comparing their rating of the most popular central line insertion videos on YouTube to expert evaluations. METHOD: YouTube search results for "central line placement" sorted by views or relevance compiled a list of the four most common videos. A fifth gold standard video, published by the New England Journal, was included, however was not found in the top results. Eleven expert practitioners from varying medical specialties (Critical Care, Surgery, Anesthesia, & Emergency Medicine) evaluated the 5 videos, utilizing a 22-item Likert scaled questionnaire emphasizing: preparation, sterility, anatomy, technique, & complications. Videos were compared as a composite average of the individual items on the survey. The highest, lowest, and 3rd ranked videos were evaluated by 45 residents ("learners") in varying specialties (Internal Medicine, Emergency Medicine, Surgery, Anesthesia) and post graduate year (PGY). Learners assessed the videos using the same scale. A Welch T-test assessed statistical significance between the two groups. Subgroup analysis compared experts against different PGY and specialty cohorts. RESULTS: The lowest scored video among the experts and learners was the most popular on YouTube, with 858,933 views at the time of inclusion. Though lowest in rank, this video was judged higher by learners than the experts (2.63/5 vs 2.18/5, P = 0.0029). The 3rd ranked video by experts with 249,746 views on YouTube, was also rated higher by learners (3.77/5 vs 3.45/5, P = 0.0084). The gold standard video by NEJM had 320,580 views and was rated highest by both the experts and learners (4.37/5 vs 4.28/5, P = 0.518). Subgroup analysis showed similar results with learners rating the videos overall better than experts, this was particularly true in the PGY-1 subgroup. CONCLUSION: The most popular central line insertion video was the worst rated by both experts and learners. Learners rated all the videos better than the expert. YouTube videos demonstrating medical procedures including central line insertion should come from peer reviewed sources if they are to be incorporated into educational curriculum.

OBJECTIVE: Dying in the intensive care unit (ICU) has changed over the last twenty years due to increased utilization of palliative care. We sought to examine how palliative medicine (PM) integration into critical care medicine has changed outcomes in end of life including the utilization of do not resuscitate (no cardiopulmonary resuscitation but continue treatment) and comfort care orders (No resuscitation, only comfort medication). Design: Retrospective observational review of critical care patients who died during admission between two decades, 2008 to 09 and 2018 to 19. Setting: Single urban tertiary care academic medical center in Washington, D.C. Patients: Adult patients who were treated in any ICU during the admission which they died. INTERVENTIONS AND MEASUREMENTS: We sought to measure PM involvement across the two decades and its association with end of life care including do not resuscitate (DNR) and comfort care (CC) orders. Main Results: 571 cases were analyzed. Mean age was 65 ± 15, 46% were female. In univariate analysis significantly more patients received PM in 2018 to 19 (40% vs. 27%, p = .002). DNR status increased significantly over time (74% to 84%, p = .002) and was significantly more common in patients who were receiving PM (96% vs. 72%, p < 0.001). CC also increased over time (56% to 70%, p = <0.001), and was more common in PM patients (87% vs. 53%, p < 0.001). Death in the ICU decreased significantly over time (94% to 86%, p = .002) and was significantly lower in PM patients (76% vs. 96%, p < 0.001). The adjusted odds of getting CC for those receiving versus those not receiving PM were 14.51 (5.49-38.36, p < 0.001) in 2008 to 09 versus 3.89 (2.27-6.68, p < 0.001) in 2018 to 19. Conclusion: PM involvement increased significantly across a decade in our ICU and was significantly associated with incidence of DNR and CC orders as well as the decreased incidence of dying in the ICU. The increase in DNR and CC orders independent of PM over the past decade reflect intensivists delivering PM services.

BACKGROUND: Coronavirus disease-2019 (COVID-19) is associated with hypercoagulability and increased thrombotic risk in critically ill patients. To our knowledge, no studies have evaluated whether aspirin use is associated with reduced risk of mechanical ventilation, intensive care unit (ICU) admission, and in-hospital mortality. METHODS: A retrospective, observational cohort study of adult patients admitted with COVID-19 to multiple hospitals in the United States between March 2020 and July 2020 was performed. The primary outcome was the need for mechanical ventilation. Secondary outcomes were ICU admission and in-hospital mortality. Adjusted hazard ratios (HRs) for study outcomes were calculated using Cox-proportional hazards models after adjustment for the effects of demographics and comorbid conditions. RESULTS: Four hundred twelve patients were included in the study. Three hundred fourteen patients (76.3%) did not receive aspirin, while 98 patients (23.7%) received aspirin within 24 hours of admission or 7 days before admission. Aspirin use had a crude association with less mechanical ventilation (35.7% aspirin versus 48.4% nonaspirin, P = .03) and ICU admission (38.8% aspirin versus 51.0% nonaspirin, P = .04), but no crude association with in-hospital mortality (26.5% aspirin versus 23.2% nonaspirin, P = .51). After adjusting for 8 confounding variables, aspirin use was independently associated with decreased risk of mechanical ventilation (adjusted HR, 0.56, 95% confidence interval [CI], 0.37-0.85, P = .007), ICU admission (adjusted HR, 0.57, 95% CI, 0.38-0.85, P = .005), and in-hospital mortality (adjusted HR, 0.53, 95% CI, 0.31-0.90, P = .02). There were no differences in major bleeding (P = .69) or overt thrombosis (P = .82) between aspirin users and nonaspirin users. CONCLUSIONS: Aspirin use may be associated with improved outcomes in hospitalized COVID-19 patients. However, a sufficiently powered randomized controlled trial is needed to assess whether a causal relationship exists between aspirin use and reduced lung injury and mortality in COVID-19 patients.

BACKGROUND: Out-of-hospital cardiac arrests are a leading global cause of mortality. The American Heart Association (AHA) promotes several important strategies associated with improved cardiac arrest (CA) outcomes, including decreasing pulse check time and maintaining a chest compression fraction (CCF) > 0.80. Video review is a potential tool to improve skills and analyse deficiencies in various situations; however, its use in improving medical resuscitation remains poorly studied in the emergency department (ED). We implemented a quality improvement initiative, which utilised video review of CA resuscitations in an effort to improve compliance with such AHA quality metrics. METHODS: A cardiopulmonary resuscitation video review team of emergency medicine residents were assembled to analyse CA resuscitations in our urban academic ED. Videos were reviewed by two residents, one of whom was a senior resident (Postgraduate Year 3 or 4), and analysed using Spearman's rank correlation coefficient for numerous quality improvement metrics, including pulse check time, CCF, time to intravenous access and time to patient attached to monitor. RESULTS: We collected data on 94 CA resuscitations between July 2017 and June 2020. Average pulse check time was 13.09 (SD ± 5.97) seconds, and 38% of pulse checks were <10 seconds. After the implementation of the video review process, there was a significant decrease in average pulse check time (P = .01) and a significant increase in CCF (P = .01) throughout the study period. CONCLUSIONS: Our study suggests that the video review and feedback process was significantly associated with improvements in AHA quality metrics for resuscitation in CA amongst patients presented to the ED.

PURPOSE: Prior research has suggested an association of hepatic venous gas with mortality in cardiac arrest. As point of care ultrasound (POCUS) is frequently used in the context of resuscitation, we sought to evaluate if the presence of hepatic gas on POCUS had a similar mortality association. METHODS: A retrospective review was conducted of patients who experienced nontraumatic cardiac arrest. Archived ultrasound images were independently reviewed to determine the presence of gas in the hepatic parenchyma and vasculature. Electronic medical records were then reviewed to collect remaining clinical data. RESULTS: From 1 January 2017 through 16 June 2019, 87 patients met inclusion criteria. Among them, 68 (78.2%) patients died. Among those who died, 40 (58.8%) had hepatic gas, while 28 (41.2%) had none. Only a single survivor demonstrated hepatic venous gas (11%). While the difference in mortality with respect to presence of undifferentiated hepatic gas was not significant (P = .37), there was a significant difference with respect to the presence of venous gas (P = .004). CONCLUSION: Our study demonstrated that the incidence of postarrest hepatic gas on POCUS was common, and that the presence of hepatic venous gas during cardiac resuscitation was associated with increased mortality, while hepatic parenchymal gas alone was not.

BACKGROUND: Several clinical trials and literature reviews have been conducted to evaluate the impact of corticosteroids on the physiological markers and clinical outcomes of patients in septic shock. While the findings have been somewhat contradictory, there is evidence of moderate benefit from the administration of low-dose corticosteroids to patients in septic shock. In this review, we discuss recent studies evaluating the impact of corticosteroids on morbidity and mortality in septic shock and explore future directions to fully elucidate when and how the administration of corticosteroid therapies can be beneficial. METHODS: A literature review was performed using the Mesh database of PubMed with the term "septic shock" and subheadings "therapeutic use", "drug therapy", "pharmacology", and "therapy" followed by the addition of "steroid". Filters were added to restrict the search to 18+ age, English and human studies, and articles published within the last 10â¯years. One hundred sixty-five articles were examined and twenty-five were deemed relevant to this review. RESULTS: The twenty-five articles reviewed here provide conflicting evidence as to the usefulness of corticosteroid treatments during septic shock. Several showed improved physiological outcomes, including rates of organ failure, need for life supporting interventions, adverse effects, inflammatory markers, and perfusion during the course of septic shock, as well as decreased mortality for a statistically significant number of patients. CONCLUSIONS: There remains a need for improved therapy for patients in septic shock. Corticosteroids have shown some potential in improving mortality rates and clinical markers. Additional studies are needed to determine the optimal role of corticosteroids in septic shock.

BACKGROUND: Fever is common among intensive care unit (ICU) patients. Clinicians may use microbiological cultures to differentiate infectious and aseptic fever. However, their utility depends on the prevalence of infection; and false-positive results might adversely affect patient care. We sought to quantify the cost and utility of microbiological cultures in a cohort of ICU patients with spontaneous intracerebral hemorrhage (ICH). METHODS: We performed a secondary analysis of a cohort with spontaneous ICH requiring mechanical ventilation. We collected baseline data, measures of systemic inflammation, microbiological culture results for the first 48 h, and daily antibiotic usage. Two physicians adjudicated true-positive and false-positive culture results using standard criteria. We calculated the cost per true-positive result and used logistic regression to test the association between false-positive results with subsequent antibiotic exposure. RESULTS: Overall, 697 subjects were included. A total of 233 subjects had 432 blood cultures obtained, with one true-positive (diagnostic yield 0.1 %, $22,200 per true-positive) and 11 false-positives. True-positive urine cultures (5 %) and sputum cultures (13 %) were more common but so were false-positives (6 and 17 %, respectively). In adjusted analysis, false-positive blood and sputum results were associated with increased antibiotic exposure. CONCLUSIONS: The yield of blood cultures early after spontaneous ICH was very low. False-positive results significantly increased the odds of antibiotic exposure. Our results support limiting the use of blood cultures in the first two days after ICU admission for spontaneous ICH.

Background: Bandemia, defined as a band count >10%, is indicative of underlying infection and is increasingly being used for early detection of sepsis. While an absolute band level has been linked to worse outcomes, its trend has not been extensively studied as a prognostic marker. In this study, we assessed patients admitted to the ICU with sepsis or septic shock and evaluated the correlation between bandemia trends and clinical trajectory among these patients. Methods: This study was a retrospective chart review. Band counts, serum lactate levels, and SOFA scores at 0 and 72 h after admission to the ICU were collected. Patients were risk stratified into groups depending on their SOFA trends, and corresponding band trends and serum lactate levels were compared. Results: 134 patients were included for analysis. There was a statistically significant decrease in bandemia trends for patients with a reduction in SOFA scores [median (IQR)-4.5 (-11, 0); p < 0.0001], and a statistically significant increase in bandemia trends for patients with worsening SOFA scores [median (IQR) 4 (0, 8); p = 0.0007]. Conclusion: Early trends of serum band levels in patients with sepsis or septic shock may help to predict a clinical trajectory and overall prognosis. More investigation is warranted as to whether incorporating bandemia trends, when used in conjunction with other known markers such as lactate levels, may help to guide bedside clinical decisions such as risk stratification, tailored therapies, and ultimately improve outcomes.
RESUMEN
BACKGROUND: The COVID-19 pandemic has significantly impacted health care workers (HCW). Most research focused on the adverse mental health effects during the initial surge of cases; and yet little is known about approximately how workers are faring 1 year into the pandemic. The objective of this study is to examine stress, burnout, and risk perception in an academic medical system, 1 year after the start of the pandemic. METHODS: HCW across care specialties participated in online surveys in Spring 2020 and Spring 2021. The surveys included questions related to workplace stress and risk perception related to COVID-19. Correlates of stress and burnout were explored using multivariable linear regression models. Professional Quality of Life Scale (PROQOL) questions were added to the second survey. RESULTS: While HCW reported significantly fewer concerns about the risk of COVID-19 transmission to themselves and their families during the 2021 survey (compared with 2020), the percentage of workers who reported feeling excess stress at work or considered resigning stayed the same. One year into the pandemic, 57% of study participants met criteria for moderate or high levels of traumatic stress and 75% met criteria for moderate or high levels of burnout. As compared with participants who cared for no COVID-19 deaths, participants who cared for COVID-19 patients who died had significantly higher traumatic stress (1 to 10: Coef. = 2.7, P = .007; >10: Coef. = 6.7, P < .001) and burnout scores (1 to 10: Coef. = 2.7, P = .004; >10: Coef. = 2.6, P = .036). CONCLUSION: While Although perceptions of risk declined over the course of the year, levels of stress still remained high despite high vaccination rates. Those who witnessed more COVID-19 deaths were more likely to report increased burnout and post-traumatic stress. As our nation continues to grapple with the COVID-19 pandemic and new variants emerge it is imperative to focus on recovery strategies for high burnout groups to ensure the wellbeing of our health care workforce.

Background: Tracheal intubation is a hazardous aerosolizing procedure with a potential risk of spreading SAR-CoV-2 between patients and physicians. Aim: The purpose of this study was to explore the impact of COVID-19 specific simulation training in improving provider level of comfort during the intubation of COVID-19 patients. Methods: In this cross-sectional national study, an electronic survey was disseminated using a snowball sample approach to intubators from 55 hospitals across the United States. The survey assessed providers' comfort of intubating and fear of contracting the virus during COVID-19 intubations. Results: A total of 329 surveys from 55 hospitals were analyzed. Of 329 providers, 111 providers (33.7%) reported participating in simulation training. Of those, 86 (77.5%) reported that the simulation training helped reduce their fear of intubating COVID-19 patients. Providers in the simulation training group also reported a higher level of comfort level with intubating both general patients (median [range] no-simulation training group 9 [3-10], simulation training group 9 [6-10]; p = 0.015) and COVID-19 patients (no-ST 8 [1-10], ST group 9 [4-10]; p < 0.0005) than providers in the no-simulation training group. Conclusions: Our study suggests that COVID-19 specific intubation simulation training promotes provider comfort. Simulation training may be implemented as part of airway management training during the current and novel pandemic situations.
RESUMEN
Infection with the SARS-CoV2 virus can vary from asymptomatic, or flu-like with moderate disease, up to critically severe. Severe disease, termed COVID-19, involves acute respiratory deterioration that is frequently fatal. To understand the highly variable presentation, and identify biomarkers for disease severity, blood RNA from COVID-19 patient in an intensive care unit was analyzed by whole transcriptome RNA sequencing. Both SARS-CoV2 infection and the severity of COVID-19 syndrome were associated with up to 25-fold increased expression of neutrophil-related transcripts, such as neutrophil defensin 1 (DEFA1), and 3-5-fold reductions in T cell related transcripts such as the T cell receptor (TCR). The DEFA1 RNA level detected SARS-CoV2 viremia with 95.5% sensitivity, when viremia was measured by ddPCR of whole blood RNA. Purified CD15+ neutrophils from COVID-19 patients were increased in abundance and showed striking increases in nuclear DNA staining by DAPI. Concurrently, they showed >10-fold higher elastase activity than normal controls, and correcting for their increased abundance, still showed 5-fold higher elastase activity per cell. Despite higher CD15+ neutrophil elastase activity, elastase activity was extremely low in plasma from the same patients. Collectively, the data supports the model that increased neutrophil and decreased T cell activity is associated with increased COVID-19 severity, and suggests that blood DEFA1 RNA levels and neutrophil elastase activity, both involved in neutrophil extracellular traps (NETs), may be informative biomarkers of host immune activity after viral infection.
