Early detection of intensive care needs and mortality risk by use of five early warning scores in patients with traumatic injuries: An observational study

Abstract

ObjectiveThe purpose of this research was to evaluate the predictive capacity of five Early Warning Scores in relation to the clinical evolution of adult patients with different types of trauma. Research MethodologyWe conducted a longitudinal, prospective, observational study, calculating the Early Warning Scores [Modified Early Warning Score (MEWS), National Early Warning Score 2 (NEWS-2), VitalPAC Early Warning Score (ViEWS), Modified Rapid Emergency Medicine Score (MREMS), and Rapid Acute Physiology Score (RAPS)] upon arrival of patients to the emergency department. SettingIn total, 445 cases of traumatic injuries were included in the study. Main Outcome MeasuresThe predictive capacity was verified with the data on admission to intensive care units (ICU) and mortality at two, seven and 30 days. Results201 patients were hospitalized and 244 were discharged after being attended in the emergency department. 91 cases (20.4%) required ICU care and 4.7% of patients died (21 patients) within two days, 6.5% (29 patients) within seven days and 9.7% (43 patients) within 30 days. The highest area under the curve for predicting the need for ICU care was obtained by the National Early Warning Score 2 and the VitalPAC Early Warning Score. For predicting mortality, the Modified Rapid Emergency Medicine Score obtained the best scores for two-day mortality, seven-day mortality and 30-day mortality. ConclusionsEvery Early Warning Score analyzed in this study obtained good results in predicting adverse effects in adult patients with traumatic injuries, creating an opportunity for new clinical applications in the emergency department.
