Role of qSOFA and SOFA Scoring Systems for Predicting In-Hospital Risk of Deterioration in the Emergency Department.

The objective of this study was to analyze and compare the usefulness of quick sequential organ failure assessment score (qSOFA) and sequential organ failure assessment (SOFA) scores for the detection of early (two-day) mortality in patients transported by emergency medical services (EMSs) to the emergency department (ED) (infectious and non-infectious). We performed a multicentric, prospective and blinded end-point study in adults transported with high priority by ambulance from the scene to the ED with the participation of five hospitals. For each score, the area under the curve (AUC) of the receiver operating characteristic (ROC) curve was calculated. We included 870 patients in the final cohort. The median age was 70 years (IQR 54-81 years), and 338 (38.8%) of the participants were women. Two-day mortality was 8.3% (73 cases), and 20.9% of cases were of an infectious pathology. For two-day mortality, the qSOFA presented an AUC of 0.812 (95% CI: 0.75-0.87; p < 0.001) globally with a sensitivity of 84.9 (95% CI: 75.0-91.4) and a specificity of 69.4 (95% CI: 66.1-72.5), and a SOFA of 0.909 (95% CI: 0.86-0.95; p < 0.001) with sensitivity of 87.7 (95% CI: 78.2-93.4) and specificity of 80.7 (95% CI: 77.4-83.3). The qSOFA score can serve as a simple initial assessment to detect high-risk patients, and the SOFA score can be used as an advanced tool to confirm organ dysfunction.

Clinical Utility of Delta Lactate for Predicting Early In-Hospital Mortality in Adult Patients: A Prospective, Multicentric, Cohort Study.

One of the challenges in the emergency department (ED) is the early identification of patients with a higher risk of clinical deterioration. The objective is to evaluate the prognostic capacity of ΔLA (correlation between prehospital lactate (pLA) and hospital lactate (hLA)) with respect to in-hospital two day mortality. We conducted a pragmatic, multicentric, prospective and blinded-endpoint study in adults who consecutively attended and were transported in advanced life support with high priority from the scene to the ED. The corresponding area under the receiver operating characteristics curve (AUROC) was obtained for each of the outcomes. In total, 1341 cases met the inclusion criteria. The median age was 71 years (interquartile range: 54-83 years), with 38.9% (521 cases) females. The total 2 day mortality included 106 patients (7.9%). The prognostic precision for the 2 day mortality of pLA and hLA was good, with an AUROC of 0.800 (95% CI: 0.74-0.85; p < 0.001) and 0.819 (95% CI: 0.76-0.86; p < 0.001), respectively. Of all patients, 31.5% (422 cases) had an ΔLA with a decrease of <10%, of which a total of 66 patients (15.6%) died. A lactate clearance ≥ 10% is associated with a lower risk of death in the ED, and this value could potentially be used as a guide to determine if a severely injured patient is improving in response to the established treatment.

Valor predictivo del preNEWS2-L (Pre-hospital National Early Warning Score 2 Lactate) para la detección de la mortalidad precoz en el ámbito prehospitalario / Predictive value of the prehospital NEWS2-L -National Early Warning Score 2 Lactate- for detecting early death after an emergency

Objetivos: Evaluar la capacidad de la escala Pre-hospital National Early Warning Score 2 lactate (preNEWS2-L) para predecir la mortalidad precoz (antes de 48 h) desde el suceso índice. Además, como objetivo secundario, analizar el rendimiento de la nueva escala para la mortalidad a 7 y 30 días por cualquier causa. Método: Estudio observacional, prospectivo y longitudinal de pacientes que son atendidos por unidades móviles de emergencias y trasladados a los servicios de urgencias de su hospital de referencia. Se recogieron variables demográficas, fisiológicas, clínicas, analíticas y de diagnóstico principal. La variable de resultado principal fue la mortalidad por cualquier causa. Resultados: Se incluyeron 707 pacientes. La mortalidad precoz tras el suceso índice antes de las primeras 48 h fue de 37 pacientes (5,2%). La escala preNEWS2-L obtuvo un área bajo la curva (ABC) de la característica operativa del receptor (COR) de 0,91 (IC 95%: 0,83-0,96; p < 0,001), 0,86 (IC 95%: 0,79-0,92; p < 0,001) y 0,82 (IC 95%: 0,760,87; p < 0,0017) para la mortalidad a 2, 7 y 30 días, respectivamente. Su capacidad de valorar la mortalidad desciende prácticamente un 10% entre el ABC-ROC a los 2 días y el ABC a los 30 días. Conclusiones: La escala generada, denominada preNEWS2-L, puede ser considerada una herramienta pronóstico muy útil para ser usada en el medio prehospitalario, por facilidad de manejo, rápida obtención y capacidad de predicción

Objectives: To evaluate the ability of the prehospital National Early Warning Score 2 Lactate (preNEWS2-L) to predict early mortality, defined as death within 48 hours of the index event. We also explored the predictive capacity of the score for 7- and 30-day all-cause mortality. Methods: Prospective, observational longitudinal study in patients attended by ambulance responders and transferred to the emergency departments of reference hospitals. We collected demographic, physiologic, clinical, and analytical data and the main diagnosis. The main outcome measure was all-cause mortality. Results: A total of 707 patients were included. Thirty-seven patients (5.2%) died within 48 hours of the index event. The area under the receiver operating characteristic curve (AUC) for the preNEWS2-L score's prediction of early death was 0.91 (95% CI, 0.83-0.96). The AUCs for death within 7 and 30 days were 0.86 (95% CI, 0.79-0.92) and 0.82 (95% CI, 0.76-0.87), respectively, showing that the score's ability to predict death decreases by almost 10% between 48 hours and 30 days. Conclusion: The preNEWS2-L is a useful prognostic tool that can be assessed quickly and easily in prehospital settings
