9±2, p<0.001) and MELD scores (29±6 vs. 22±8, p<0.001), higher serum international normalized ratio (1.7 vs.1.4, p=0.03), bilirubin (6.0 vs. 3.3mg/dL, p=0.02), lactate (5.4 vs. 2.7mmol/L, p<0.01), creatinine (2.2 vs. 1.6mg/dL, p=0.04), higher neutrophil-to-lymphocyte ratio (13.0 vs. 10.3, p=0.02), and lower LMR (1.1 vs. 2.3, p<0.01). The LMR (adjusted hazard ratio [aHR]=1.54, p=0.01) and lactate (aHR=1.03, p<0.01) were identified as independent predictive factors for mortality in the multivariate regression model. Furthermore, LMR (area under curve [AUC] 0.87) revealed a superior discrimination ability in mortality prediction compared with the Child-Pugh (AUC 0.72) and MELD (AUC 0.76) scores.

The LMR can be used to predict mortality risk in cirrhotic patients with septic shock.

Quality management of Acute Kidney Injury (AKI) is dependent on early detection, which is currently deemed to be suboptimal. The aim of this study was to identify combinations of variables associated with AKI and to derive a prediction tool for detecting patients attending the emergency department (ED) or hospital with AKI (ED-AKI).

This retrospective observational study was conducted in the ED of a tertiary university hospital in Wales. Between April and August 2016 20,421 adult patients attended the ED of a University Hospital in Wales and had a serum creatinine measurement. Using an electronic AKI reporting system, 548 incident adult ED-AKI patients were identified and compared to a randomly selected cohort of adult non-AKI ED patients (n=571). A prediction model for AKI was derived and subsequently internally validated using bootstrapping. The primary outcome measure was the number of patients with ED-AKI.

In 1119 subjects, 27 variables were evaluated. Four ED-AKI models were generated with C-statistics ranging from 0.800 to 0.765. The simplest and most practical multivariate model (model 3) included eight variables that could all be assessed at ED arrival. A 31-point score was derived where 0 is minimal risk of ED-AKI. The model discrimination was adequate (C-statistic 0.793) and calibration was good (Hosmer & Lomeshow test 27.4). ED-AKI could be ruled out with a score of <2.5 (sensitivity 95%). Internal validation using bootstrapping yielded an optimal Youden index of 0.49 with sensitivity of 80% and specificity of 68%.

A risk-stratification model for ED-AKI has been derived and internally validated. The discrimination of this model is objective and adequate. It requires refinement and external validation in more generalisable settings.

We sought to determine if emergency physician providers working in the triage area (PIT) of the ED could accurately predict the likelihood of admission for patients at the time of triage. Such predictions, if accurate, could decrease the time spent in the ED for patients who are admitted to the hospital by hastening downstream workflow.

This is a prospective cohort study of PIT providers at a large urban hospital. Physicians were asked to predict the likelihood of admission and confidence of prediction for patients after evaluating them in triage. Measures of predictive accuracy were calculated, including sensitivity, specificity, and area under the receiver operator characteristic (AUROC).

36 physicians (20 attendings, 16 residents) evaluated 340 patients and made predictions. The average patient age was 48 (range 18-94) and 52% were female. Seventy-three patients (21%) were admitted (5% observation, 85% general care/telemetry, 7% progressive care, 3% ICU). The sensitivity of determining admission for the entire cohort was 74%, the specificity was 84%, and the AUROC was 0.81. When physicians were at least 80% confident in their predictions, the predictions improved to sensitivity of 93%, specificity of 96%, and AUROC 0.95 (Graph 1).

The accuracy of physician providers-in-triage of predicting hospital admission was very good when those predictions were made with higher degrees of confidence. These results indicate that while general predictions of admission are likely inadequate to guide downstream workflow, predictions in which the physician is confident could provide utility.

This study seeks to determine the utility of D-dimer levels as a biomarker in determining disease severity and prognosis in COVID-19.

Clinical, imaging and laboratory data of 120 patients whose COVID-19 diagnosis based on RT-PCR were evaluated retrospectively. Clinically, the severity of COVID-19 was classified as noncomplicated or mild or severe pneumonia. selleck products Radiologically, the area of affected lungs compatible with viral pneumonia in each patient's computed tomography was classified as either 0-30% or≥31% of the total lung area. The D-dimer values and laboratory data of patients with COVID-19 were compared with inpatient status, duration of hospitalization, and lung involvement during treatment and follow-up. To assess the predictive value of D-dimer, receiver operating characteristic (ROC) analysis was conducted.

D-dimer elevation (> 243ng/ml) was detected in 63.3% (76/120) of the patients. The mean D-dimer value was calculated as 3144.50±1709.4ng/ml (1643-8548) for inpatients with severe pneumonia in the intensive care unit. D-Dimer values showed positive correlations with age, duration of stay, lung involvement, fibrinogen, neutrophil count, neutrophil lymphocyte ratio (NLR) and platelet lymphocyte ratio (PLR). When the threshold D-dimer value was 370ng/ml in the ROC analysis, this value was calculated to have 77% specificity and 74% sensitivity for lung involvement in patients with COVID-19.

D-Dimer levels in patients with COVID-19 correlate with outcome, but further studies are needed to see how useful they are in determining prognosis.
