The National Early Warning Score + Lactate (NEWS+L) Score has been previously shown to outperform NEWS alone in prediction of mortality and need for critical care in a small adult ED study. We ...validated the score in a large patient data set and constructed a model that allows early prediction of the probability of clinical outcomes based on the individual's NEWS+L Score.
In this retrospective study, we included all adult patients who visited the ED of a single urban academic tertiary-care university hospital in South Korea for five consecutive years (1 January 2015 to 31 December 2019). The initial (<1 hour) NEWS+L Score is routinely recorded electronically at our ED and was abstracted for each visit. The outcomes were hospital death or a composite of hospital death and intensive care unit admission at 24 hours, 48 hours and 72 hours. The data set was randomly split into train and test sets (1:1) for internal validation. The area under the receiver operating characteristic curve (AUROC) value and area under the precision and recall curve (AUPRC) value were evaluated and logistic regression models were used to develop an equation to calculate the predicted probabilities for each of these outcomes according to the NEWS+L Score.
After excluding 808 patients (0.5%) from 149 007 patients in total, the study cohort consisted of 148 199 patients. The mean NEWS+L Score was 3.3±3.8. The AUROC value was 0.789~0.813 for the NEWS+L Score with good calibration (calibration-in-the-large=-0.082~0.001, slope=0.964~0.987, Brier Score=0.011~0.065). The AUPRC values of the NEWS+L Score for outcomes were 0.331~0.415. The AUROC and AUPRC values of the NEWS+L Score were greater than those of NEWS alone (AUROC 0.744~0.806 and AUPRC 0.316~0.380 for NEWS). Using the equation, 48 hours hospital mortality rates for NEWS+L Score of 5, 10 and 15 were found to be 1.1%, 3.1% and 8.8%, and for the composite outcome 9.2%, 27.5% and 58.5%, respectively.
The NEWS+L Score has acceptable to excellent performance for risk estimation among undifferentiated adult ED patients, and outperforms NEWS alone.
The aim of this study was to evaluate the performance of the Sequential Organ Failure Assessment (SOFA) score and the newly introduced criteria, traumasis, defined as a SOFA score 2 or more among ...trauma patients.
Consecutive adult traffic collision patients who were admitted to the study hospital emergency department (ED) from January 2017 to December 2018 were enrolled retrospectively in the study. The primary outcome was in-hospital death. The SOFA score was calculated using relevant initial ED data. Traditional risk scores for trauma patients, such as the injury severity score (ISS), the revised trauma score (RTS), and the trauma injury severity score (TRISS), were also calculated.
A total of 927 patients were available for analysis, of whom 46 died (5.0%). The median SOFA score was 1.0 (interquartile range IQR, 0.0–3.0). A total of 417 patients (45.0%) were identified as having traumasis (SOFA score ≥ 2), of whom 44 died (10.6%). The area under the receiver operating characteristic (AUROC) curve of the SOFA score (0.91; 95% confidence interval CI 0.87–0.95) was comparable with that of the TRISS (0.88; 95% CI, 0.84–0.93) and better than that of the ISS(0.81; 95% CI 0.75–0.86) and the RTS (0.82; 95% CI 0.75–0.90). The sensitivity, specificity, positive predictive value and negative predictive value of the traumasis criteria for the primary outcome were 95.7%, 63.0%, 11.9%, and 99.6%, respectively. The net reclassification improvement for the comparison between the traumasis criteria and major trauma criteria (ISS ≥ 15) was 0.69 (95% CI, 0.55–0.82; p < 0.001). The multivariate Cox regression model showed that the SOFA score (adjusted hazard ratio aHR 1.52; 95% CI 1.37–1.67) and traumasis (aHR 11.40; 95% CI 2.70–48.13), respectively, was independently associated with higher in-hospital mortality.
The SOFA score can be used as a reliable tool for predicting in-hospital death among traffic collision patients. The newly introduced criteria, traumasis, may be used as a risk-stratification and quality-control criteria among patients with trauma, similar to the sepsis criteria among patients with infectious disease.
To determine the incidence of acute cerebral infarction or space occupying lesion (SOL) among patients with isolated vertigo or dizziness (IVD) and to evaluate the role of cerebellar function test ...(CFT) and D-dimer to discriminate ACI/SOL and non-ACI/SOL.
A retrospective study of consecutive emergency department (ED) patients with IVD during one year was conducted. ACI was based on the diffusion-weighted magnetic resonance imaging (DW-MRI), and SOL was based on the concurrent MRI sequences. A sensitivity analysis of CFT and D-dimer was also performed.
Among the 468 patients enrolled, 13 patients (2.8%) had ACI, 11 at cerebellum, 1 at occipital lobe, and 1 at centrum semiovale. Twenty-five patients (5.3%) had SOL. Aneurysm is most frequent (n = 7), followed by meningioma (n = 4) and venous anomaly (n = 4). In total, ACI/SOL was found in 8.1% (n = 38). Abnormal findings in finger-to-nose (FN), heel-to-shin (HTS), and rapid alternative movement (RAM) tests were significantly higher in ACI or ACI/SOL group, while gait disturbance, tandem gait abnormality, and Romberg's test were not. CFT sensitivities were low for ACI as well as for ACI/SOL, but specificities were high for ACI and ACI/SOL. D-dimer level showed a sensitivity of 100% at >0.18 mg/L for ACI and >0.15 mg/L for ACI/SOL. However, specificity was low at corresponding D-dimer level. Among the subgroup (n = 411) who did not show any abnormality in CFT, 9 patients (2.2%) had ACI, and 33 patients (8.0%) had ACI/SOL.
The present study reports a clinically significant incidence of ACI/SOL among ED patients with IVD. D-dimer showed high sensitive and low specificity, while CFT showed low sensitivity and high specificity.

The head-tilt/chin-lift (HT/CL) maneuver is simple and routinely used to open a closed upper airway.
It has yet to be determined whether increasing the HT/CL angle further would be beneficial.
We ...enrolled 60 (30 males) 20-year-old conscious participants. Pre-HT/CL, post-HT/CL #1, and post-HT/CL #2 positions were defined as positions in which the angle between the ear-eye line and the horizontal line was 80°, 65°, and 50°, respectively. Peak exploratory flow rates (PEFRs) pre-HT/CL, post-HT/CL #1, and post-HT/CL #2 positions were recorded continuously at 1-minute intervals (one set). Five sets of measurements were performed (total, 15 measurements for each participant).
We analysed 900 measurements (180 sets). The mean PEFRs pre-HT/CL, post-HT/CL #1, and post-HT/CL #2 positions were 348.4 ± 96.9, 366.4 ± 104.9, and 378.8 ± 111.2 L/min (percentage change compared to pre-HT/CL, 5.2% and 8.7%), respectively. Significant differences were observed among pre-HT/CL, post-HT/CL #1, and post-HT/CL #2 positions in all participants, as well as in subgroup classified according to sex, and medians of height, body weight, and body mass index.
Our findings suggest that a greater HT/CL angle would be beneficial, as the PEFR increased gradually. The decreasing manner in the PEFR increase with the HT/CL angle implies the existence of an angle threshold beyond which there were no further benefits in airflow, indicating a minimum in airway resistance. A HT/CL maneuver may be appropriate until locking the atlanto-occipital and cervical spine joints in extension occurs and the chest (sternal notch) begins to rise.

The predictive value of serum albumin in adult aspiration pneumonia patients remains unknown.
Using data collected during a 3-year retrospective cohort of hospitalized adult patients with aspiration ...pneumonia, we evaluated the predictive value of serum albumin level at ED presentation for in-hospital mortality.
248 Patients were enrolled; of these, 51 cases died (20.6%). The mean serum albumin level was 3.4±0.7g/dL and serum albumin levels were significantly lower in the non-survivor group than in the survivor group (3.0±0.6g/dL vs. 3.5±0.6g/dL). In the multivariable logistic regression model, albumin was associated with in-hospital mortality significantly (adjusted odds ratio 0.30, 95% confidential interval (CI) 0.16–0.57). The area under the receiver operating characteristics (AUROC) for in-hospital survival was 0.72 (95% CI 0.64–0.80). The Youden index was 3.2g/dL and corresponding sensitivity, specificity, positive predictive value, negative predictive value, positive and negative likelihood ratio were 68.6%, 66.5%, 34.7%, 89.1%, 2.05 and 0.47, respectively. High sensitivity (98.0%) was shown at albumin level of 4.0g/dL and high specificity (94.9%) was shown at level of 2.5g/dL.
Initial serum albumin levels were independently associated with in-hospital mortality among adult patients hospitalized with aspiration pneumonia and demonstrated fair discriminative performance in the prediction of in-hospital mortality.
Local applications of tranexamic acid (TXA) have been effective in treating various hemorrhagic conditions. In patients with gross hematuria, the main treatment in the emergency department (ED) is ...continuous bladder irrigation (CBI). However, CBI has no pharmacological effects except blood clot removal from dilution. The aim of this study was to evaluate the impact of the intravesical TXA injection before CBI.
This study was a before-and-after, retrospective, and single-center study. The target population was hematuria patients who received CBI via a 3-way Foley catheter. As the intervention procedure, 1000 mg of TXA was injected through the Foley catheter and after 15 min, the Foley catheter was declamped and CBI started. Since the intervention started in March 2022, the patients from March 2022 to August 2022 were assigned to the after group and the patients from March 2021 to August 2021 were assigned to the before group. The primary outcomes were the length of stay in the ED and duration of Foley catheter placement. The secondary outcomes were the admissions and the revisits for CBI within 48 h after discharge.
The numbers of patients in the before group and after group were 73 and 86, respectively. The median length of stay in the ED was shorter in the intervention group than in the group not treated with TXA (274 min vs. 411 mins, P < 0.001). The median duration of Foley catheter placement was also shorter in the intervention group than not treated with TXA (145 min vs. 308 mins, P < 0.001). The revisits after ED discharge were lower in the after group than in the before group (2.3% vs. 12.3%, P = 0.031). There was a trend for lower admissions in the TXA treatment group than before group (29.1% vs. 45.2%, P = 0.052).
After the TXA intervention, reduction in the length of stay in the ED, the duration of Foley catheter placement, and the revisits after ED discharge was observed.
Abstract Background Adverse effects of emergency department (ED) crowding among critically ill patients are not well known. Objectives We evaluated the association between ED crowding and inpatient ...mortality among critically ill patients admitted via the ED, and analyzed subsets of patients according to admission diagnosis. Methods We performed a post hoc analysis using data from a previous retrospective study. We enrolled admitted patients via the ED with an initial systolic blood pressure of 90 mm Hg or lower when presenting to the ED. The ED occupancy ratio was used as a measure of crowding. The primary outcome was inpatient mortality. Multivariable logistic regression models adjusted for potential confounding variables were constructed for the entire cohort and for subsets according to admission diagnosis (infection, cardiac and vascular disease, trauma, gastrointestinal bleeding, and other factors). Results A total of 1801 patients were enrolled, with a mortality rate of 14.6% (262 patients). The mortality rate by ED occupancy ratio quartile was 9.7% for the first quartile, 15.9% for the second quartile, 18.2% for the third quartile, and 14.4% for the fourth quartile. This resulted in adjusted odds ratios of 1.95, 2.51, and 1.93 and corresponding 95% confidence intervals of 1.23-3.12, 1.58-3.99, and 1.21-3.09 for the second, third, and fourth quartiles, respectively, compared with the first quartile. The effect of ED crowding was highest in the trauma subset, followed by the infection subset, whereas ED crowding did not appear to have any effect on the cardiac and vascular disease subsets. Conclusion Emergency department crowding was associated with increased inpatient mortality among critically ill patients admitted via the ED.
