Methods: An observational prospective cohort study of 2116 patients with CAP was performed. Construct validity was determined using Cronbach α. Discrimination was assessed using the area under the receiver operating characteristic curve (AUROC) and net reclassification improvement (NRI). Results: Overall in-hospital mortality was 6.43%. Mortality was 25.96% for patients with a qSOFA score of 2 or higher versus 3.05% for those with a qSOFA score less than 2 (odds ratio for mortality 6.57, P < 0.0001), and 13.85% for patients with at least 3 minor criteria versus 2.03% for those with 2 or fewer minor criteria (odds ratio for mortality 2.27, P < 0.0001). qSOFA had a higher correlation with mortality than minor criteria, as well as higher internal consistency (Cronbach alpha 0.43 versus 0.14) and diagnostic values of individual elements (larger AUROCs and higher Youden's indices). qSOFA ≥2 was less sensitive but more specific for predicting mortality than ≥3 minor criteria (qSOFA sensitivity 59.6%, specificity 88.3% and positive likelihood ratio 5.11 versus ≥3 minor criteria sensitivity 80.1%, specificity 65.8% and positive likelihood ratio 2.34). The predictive validity of qSOFA was good for mortality (AUROC = 0.868), was statistically greater than minor criteria, was equal to pneumonia severity index, and was inferior compared with CURB-65 (AUROC, 0.824, 0.902, 0.919; NRI, 0.088, ?0.068, ?0.103; respectively). Conclusions: The qSOFA predicted mortality in CAP better than IDSA/ATS minor criteria and worse than CURB-65 with robust elements and higher convergence. qSOFA as a bedside prompt might be positioned as a proxy for minor criteria and increase the recognition and thus merit more appropriate management of CAP patients likely to fare poorly, which might have implications for more accurate clinical triage decisions.

    查看更多>>摘要：? 2021 Elsevier Inc.Introduction: The incidence of alcohol and recreational drug use is increasing. The impact on penetrating trauma is unknown. This study was undertaken to identify the incidence of alcohol and recreational drug use prior to penetrating trauma, and to identify ISS and outcomes among patients with penetrating trauma. Methods: In this retrospective study, eligible subjects included trauma patients age 18 and older, with major trauma (admitted or evaluated by the Trauma Team) from 2017 to 2021. A chart review was conducted to identify data including mechanism of injury, ISS, alcohol level, toxicologic testing, length of stay, and final disposition. Results: Among 1270 adult subjects with penetrating trauma during 2017 through 2020, the majority were male (N = 1071; 84%), and African American (N = 679; 54.3%) or White (N = 537; 42.9%). Mechanisms of injury included gunshot wound (GSW) (N = 973; 76.6%) or stab wound (N = 297; 23.4%). Injury severity score (ISS) ranged from 1 to 75. Among 426 subjects (33.5%) tested for recreational drugs, 395 (93%) were positive for at least one substance. The most common recreational drugs identified included marijuana (N = 280; 65.7%), benzodiazepine ((N = 131;30.8%), alcohol ((N = 248; 25.3%), opiate ((N = 116; 27.2%), cocaine (N = 87; 20.4%), and amphetamine ((N = 84; 19.7%). Subjects with an ISS of 9 to 15 had higher odds of testing positive for opiates compared to subjects with an ISS of 1 to 3 (OR 2.3). Most patients were ultimately discharged home ((N = 912;71.8%) and a minority expired (N = 142; 11.2%). Conclusions: Positive screens for alcohol and recreational drugs were common among penetrating trauma patients in this setting. The most common identified recreational drugs included marijuana, benzodiazepine, opiates, alcohol, cocaine, and amphetamine.

    查看更多>>摘要：? 2021 The AuthorsIntroduction: Intrahospital transport of critically ill patients is often necessary for diagnostic procedures, therapeutic procedures, or admission to the intensive care unit. The aim of this study was to investigate and describe safety and adverse events during intrahospital transport of critically ill patients. Material and methods: A systematic search was performed of MEDLINE and the Cochrane Central Register of Controlled Trials for studies published up to June 3, 2020, and of the International Clinical Trials Platform Search Portal and ClinicalTrials.gov for ongoing trials. We selected prospective and retrospective cohort studies published in English on intrahospital transport of critically ill patients, and then performed a meta-analysis. The primary outcome was the incidence of all adverse events that occurred during intrahospital transport. The secondary outcomes were death due to intrahospital transport or life-threatening adverse events, minor events in vital signs, adverse events related to equipment, durations of ICU and hospital stay, and costs. Results: A total of 12,313 intrahospital transports and 1898 patients from 24 studies were included in the meta-analysis. Among 24 studies that evaluated the primary outcome, the pooled frequency of all adverse events was 26.2% (95% CI: 15.0–39.2) and the heterogeneity among these studies was high (I2 = 99.5%). The pooled frequency of death due to intrahospital transport and life-threatening adverse events was 0% and 1.47% each, but heterogeneity was also high. Conclusions: Our findings suggest that adverse events can occur during intrahospital transport of critically ill patients, and that the frequency of critical adverse events is relatively low. The results of this meta-analysis could assist in risk-benefit analysis of diagnostic or therapeutic procedures requiring intrahospital transport of critically ill patients. Trial registration: UMIN000040963.

    查看更多>>摘要：? 2021 Elsevier Inc.Background: Quick identification of patients with mild ischemic stroke complaining of dizziness from other patients with benign peripheral vestibular disorders who also experience dizziness in the emergency department (ED) may be difficult. Decision-making on intravenous thrombolysis therapy (IVT) in patients whose chief symptoms include acute dizziness or vertigo remains a severe challenge for ED physicians. This study evaluated the diagnosis, treatment processes and the short-term outcomes in patients with mild vestibular stroke in the ED. Methods: A total of 89 consecutive patients with mild ischemic stroke primarily presenting with vestibular symptoms, who arrived at ED within 4.5 after onset, and were admitted at the stroke center of Zhejiang Provincial People's Hospital between January 2015 and March 2021 were retrospectively enrolled. Patients treated with IVT (n = 47) were compared to patients without IVT (n = 42) in terms of demographics, onset-to-door time (ODT), baseline clinical characteristics, risk factors of stroke, imaging findings, and short-term outcomes. The correlation between these parameters and IVT decision-making was analyzed. Results: Patients in IVT group more frequently presented with shorter ODT, focal neurological deficits (dysarthria, facial palsy, hemiglossoplegia, hemiparesis, hemisensory loss), disabling deficits, higher baseline National Institute of Health Stroke Scale (NIHSS) scores, and underwent multi-mode imaging before a decision. A higher proportion of isolated vestibular symptoms, acute transient vestibular syndrome, and vestibulo-vagal symptoms were found in the no-IVT group. There were no differences in demographics between the two groups. ODT was negatively correlated with the decision-making on IVT, and baseline NIHSS scores were positively correlated with the decision-making on IVT. Conclusion: ODT and baseline NIHSS scores were correlated with the IVT decision in mild stroke patients primarily presenting with vestibular symptoms. Severe vestibular symptoms and disabling deficits were weakly associated with IVT decision, while the vestibulo-oculomotor signs and multi-mode imaging did not result as the influencing factors promoting the IVT decision-making for mild vestibular stroke.

    查看更多>>摘要：? 2021 Elsevier Inc.Background: Among acute heart failure (AHF) inpatients, right ventricular dysfunction (RVD) predicts clinical outcomes independent of left ventricular (LV) dysfunction. Prior studies have not accounted for congestion severity, show conflicting findings on echocardiography (echo) timing, and excluded emergency department (ED) patients. We describe for the first time the epidemiology, predictors, and outcomes of RVD in AHF starting with earliest ED treatment. Methods: Point-of-care echo and 10-point lung ultrasound (LUS) were obtained in 84 prospectively enrolled AHF patients at two EDs, ≤1 h after first intravenous diuresis, vasodilator, and/or positive pressure ventilation (PPV). Echo and LUS were repeated at 24, 72, and 168 h, unless discharged sooner (n = 197 exams). RVD was defined as <17 mm tricuspid annulus plane systolic excursion (TAPSE), our primary measure. To identify correlates of RVD, a multivariable linear mixed model (LMM) of TAPSE through time was fit. Possible predictors were specified a priori and/or with p ≤ 0.1 difference between patients with/without RVD. Data were standardized and centered to facilitate comparison of relative strength of association between predictors of TAPSE. Survival curves for a 30-day death or AHF readmission primary outcome were assessed for RVD, LUS severity, and LVEF. A multivariable generalized linear mixed model (GLMM) for the outcome was used to adjust RVD for LVEF and LUS. Results: 46% (n = 39) of patients at ED arrival showed RVD by TAPSE (median 18 mm, interquartile range 13–23). 18 variables with p ≤ 0.1 unadjusted difference with/without RVD, and 12 a priori predictors of RVD were included in the multivariable LMM model of TAPSE through time (R2 = 0.76). Missed antihypertensive medication (within 7 days), ED PPV, chronic obstructive pulmonary disease history, LVEF, LUS congestion severity, and right ventricular systolic pressure (RVSP) were the strongest multivariable predictors of RVD, respectively, and the only to reach statistical significance (p < 0.05). 30-day death or AHF readmission was associated with RVD at ED arrival (hazard ratio {HR} 3.31 {95%CI: 1.28–8.53}, p = 0.009), ED to discharge decrease in LUS (HR 0.11 {0.01–0.85}, p < 0.0001 for top quartile Δ), but not LVEF (quartile 2 vs. 1 HR 0.78 {0.22–2.68}, 3 vs. 1 HR 0.55 {0.16–1.92}, 4 vs. 1 HR 0.32 {0.09–1.22}, p = 0.30). The area under the receiver operating curve on GLMM for the primary outcome by TAPSE (p = 0.0012), ΔLUS (p = 0.0005), and LVEF (p = 0.8347) was 0.807. Conclusion: In this observational study, RVD was common in AHF, and predicted by congestion on LUS, LVEF, RVSP, and comorbidities from ED arrival through discharge. 30-day death or AHF-rehospitalization was associated with RVD at ED arrival and ΔLUS severity, but not LVEF.

    查看更多>>摘要：? 2021 Elsevier Inc.Background: Out-of-hospital cardiac arrests (OHCAs) are a leading cause of mortality in the United States. The ongoing COVID-19 pandemic has dramatically altered the landscape of response to OHCAs, particularly with regard to providing cardiopulmonary resuscitation (CPR). We aimed to describe, characterize, and address the attitudes and concerns of healthcare workers towards CPR of OHCA patients during the COVID-19 pandemic. Methods: We performed a cross-sectional study of healthcare workers and trainees in the United States and Saudi Arabia via an online survey available between October 2020, and May 2021. The primary outcome of interest was willingness to perform CPR for OHCA, with confidence to handle CPR for OHCA as our secondary outcome. Results: A total of 501 healthcare professionals, including 436 (87%) with background in emergency medicine, participated in our survey. 331 (66%) reported being willing to perform CPR for OHCA, while 170 (34%) were not willing. 311 (94%) willing participants stated that their medical oath and moral responsibility were the main motivators for willingness, while a fear of contracting COVID-19 was the primary demotivating factor for 126 (74%) unwilling participants. Time series analysis with simple exponential smoothing showed an increase in willingness to perform CPR from 30% to 50%, as well as an increase in mean confidence level to perform CPR from 60% to 70%, between October 2020 and May 2021. Conclusions: The ongoing COVID-19 pandemic significantly affected healthcare workers' attitudes towards performing CPR for OHCA. Confidence levels and willingness to perform CPR increased over time during the study period. Efforts should be directed towards the creation of standardized and evidence-based guidelines for CPR during COVID-19, as well as increasing knowledge regarding risks of infection and effective use of PPE during resuscitation.

    查看更多>>摘要：? 2021 Elsevier Inc.Background: There is limited evidence to support the efficacy and safety of push-dose vasopressor (PDP) use outside of the operating room (OR). Specifically, there are few head-to-head comparisons of different PDP in these settings. The purpose of this study was to compare the efficacy and safety of push-dose phenylephrine (PDP-PE) and epinephrine (PDP-E) in the Emergency Department (ED). Methods: This retrospective, single-center study evaluated adults given PDP-PE or PDP-E in the ED from May 2017 to November 2020. The primary outcome was a change in heart rate (HR). Secondary outcomes included changes in blood pressure, adverse effects, dosing errors, fluid and vasopressor requirements, ICU and hospital lengths of stay (LOS), and in-hospital mortality. Results: Ninety-six patients were included in the PDP-PE group and 39 patients in the PDP-E group. Median changes in HR were 0 [?7, 6] and ? 2 [?15, 5] beats per minute (BPM) for PDP-PE and PDP-E, respectively (p = 0.138). PDP-E patients had a greater median increase in systolic blood pressure (SBP) (33 [24, 53] vs. 26 [8, 51] mmHg; p = 0.049). Dosing errors occurred more frequently in patients that received PDP-E (5/39 [12.8%] vs. 2/96 [2.1%]; p = 0.021). PDP-E patients more frequently received continuous epinephrine infusions before and after receiving PDP-E. There were no differences in adverse effects, fluid requirements, LOS, or mortality. Conclusion: PDP-E provided a greater increase in SBP compared to PDP-PE. However, dosing errors occurred more frequently in those receiving PDP-E. Larger head-to-head studies are necessary to further evaluate the efficacy and safety of PDP-E and PDP-PE.

    查看更多>>摘要：? 2021 Elsevier Inc.Objectives: A comparative examination of the clinical, laboratory, ultrasound findings, and operative characteristics of rare site located ectopic pregnancies. Methods: Retrospective analysis of all department cases of rare site located ectopic pregnancies diagnosed and treated from December 2006 to December 2019. Results: Thirty rare ectopic pregnancies were identified. Of these, 11 were ovarian, 10 were interstitial and 9 were tubal stump. The patients treated for ovarian pregnancy had significantly lower human chorionic gonadotropin (hCG) levels than patients treated for interstitial or stump pregnancies (2025 ± 1105 mIU/ml, 18,424 ± 2579 mIU/ml and 11,204 ± 9221 mIU/ml, respectively, p = 0.003). The main presenting symptom in patients with an ovarian pregnancy was abdominal pain (90.9%, 60.0% and 44.4%, respectively, p = 0.031). Signs of abdominal peritoneal irritation (i.e., rebound tenderness and guarding) were more frequent upon physical examination in patients with an ovarian pregnancy (72.2%, 30.0% and 22.2%, respectively, p = 0.044) who also exhibited the highest rates of syncope and hypovolemic shock upon admission compared to patients with an interstitial or stump pregnancy (54.5%, 10.0% and 11.1%, respectively, p = 0.031). Ovarian pregnancies were associated with the lowest sonographic detection rates (9.1%, 80.0% and 100%, respectively, p = 0.0001) and with free fluid in the pouch of Douglas (72.7%, 20.0% and 22.2%, respectively, p = 0.02). Ovarian pregnancies experienced the highest rupture rate during surgery compared to interstitial or stump pregnancies (66.9%, 16.7% and 44.4%, respectively, p = 0.028), had a significantly higher estimated blood loss (1081 ± 647 ml, 760 ± 597 ml and 343 ± 318 ml, respectively, p = 0.003) and required blood transfusions in the perioperative period (63.6%, 20.0% and 11.1%, respectively, p = 0.025) significantly more often. Conclusions: Ovarian pregnancy remains the most challenging diagnosis compared to interstitial and tubal stump ectopic's. Health care providers should recognize these rare site ectopic pregnancies and to handle these gynecological emergencies promptly.

    查看更多>>摘要：? 2021 Elsevier Inc.Purpose: To verify the role of lactate dehydrogenase to albumin (LDH/ALB) ratio as an independent prognostic factor for mortality due to the lower respiratory tract infection (LRTI) in the emergency department (ED). Methods: We reviewed the electronic medical records of patients who were admitted to the ED for the management of LRTI between January 2018 and December 2020. Initial vital signs, laboratory data, and patient severity scores in the ED were collected. The LDH/ALB ratio was compared to other albumin-based ratios (blood urea nitrogen to albumin ratio, C-reactive protein to albumin ratio, and lactate to albumin ratio) and severity scales (pneumonia severity index, modified early warning score, CURB-65 scores), which are being used as prognostic factors for in-hospital mortality. Multivariable logistic regression was performed to identify independent risk factors. Results: The LDH/ALB ratio was higher in the non-survivor group than in the survivor group (median [interquartile range]: 217.6 [160.3;312.0] vs. 126.4 [100.3;165.1], p < 0.001). In the comparison of the area under the receiver operating characteristic curve (AUC) for predicting in-hospital mortality, the AUC of the LDH/ALB ratio (0.808, 95% confidence interval: 0.757–0.842, p < 0.001) was wider than other albumin-based ratios and severity scales, except the blood urea nitrogen to albumin ratio. In the multivariable logistic regression analysis, the LDH/ALB ratio independently affected in-hospital mortality. Conclusion: The LDH/ALB ratio may serve as an independent prognostic factor for in-hospital mortality in patients with LRTI.

    查看更多>>摘要：? 2021 Elsevier Inc.Introduction: Serologic testing can provide a safe and fast approach for assessing SARS-CoV-2 antibodies. These tests can be utilized as a complementary method in diagnosis and patients' follow-up, and can also be helpful in epidemiological studies. This study aimed to describe temporal changes in the incidence of COVID-19 IgM and IgG antibodies in emergency medical technicians (EMTs) within a specified time period. Methods: All EMTs working for Tehran Emergency Medical Service (EMS) center during May to September 2020 were eligible for this study. Those EMTs who were suspected/probable/confirmed cases of COVID-19, based on WHO defined criteria and were willing to participate, entered the study. The EMTs underwent serology testing four weeks after the occurrence of exposure (in suspected cases) or onset of their symptoms (in probable/confirmed cases). Cases were further confirmed by RT-PCR and/or lung CT, and antibody testing was performed for the second and third time with 12-week intervals. Finger-stick blood sampling was utilized for the specimen collection in three different phases. Samples were then analyzed by a commercial immunochromatography-based kit for qualitative measurement of serum IgM and IgG antibodies against the COVID-19 S-protein antigen. Results: Two hundred eighty-four participants met the inclusion criteria; their mean age was 35.9 (SD = 7.6) years and consisted of 244 (85.9%) males. COVID-19 was confirmed in 169 out of 284 participants. Subsequently, 142 and 122 participants were included in phases 2 and 3 of the study, respectively. The number of seronegative patients exceeded seropositive ones in all three phases. At baseline, 162 (57%) patients were seronegative, 27 (9.5%) were only positive for IgG, 3 (1.1%) were only positive for IgM, and 92 (32.4%) were positive for both antibodies; Seventy-eight (54.9%) were seronegative, and 31 (21.8%) were positive for both antibodies in the second phase; These values were 85 (69.6%) and 8 (6.6%) for the third phase, respectively. Among the people who were positive IgG in the first phase (80 people), 56.3% were still positive in the second phase and 27.5% in both subsequent phases. Conclusion: The results of our study show that there is a significant reduction in COVID-19 antibody seropositivity over time.
