BackgroundFor decades, trauma has been recognized globally as a major cause of death. Reducing the mortality of patients with trauma is an extremely pressing issue, particularly for those with severe trauma. An early and accurate assessment of the risk of mortality among patients with severe trauma is important for improving patient outcomes.MethodsWe performed a retrospective medical record review of 582 patients with severe trauma admitted to the emergency department between July 2011 and June 2016. We analyzed the associations of in-hospital mortality with the baseline characteristics and initial biochemical markers of patients with severe trauma on admission.ResultsThe overall in-hospital mortality rate was 14.9%. Multivariate logistic regression analysis showed that the patient's Rapid Emergency Medicine Score (REMS; odds ratio [OR], 1.186; 95% confidence interval [CI], 1.018-1.383; p=0.029), Emergency Trauma Score (EMTRAS; OR, 2.168; 95% CI, 1.570-2.994; p<0.001), serum lactate levels (SLL; OR, 1.298; 95% CI, 1.118-1.507; p<0.001), and Injury Severity Score (ISS; OR, 1.038; 95% CI, 1.010-1.130; p=0.021) were significantly associated with in-hospital mortality.ConclusionThe REMS, EMTRAS, and SLL can easily and rapidly be used as alternatives to the injury severity score to predict in-hospital mortality for patients who present to the emergency department with severe trauma.Copyright © 2019 by The Korean Society for Thoracic and Cardiovascular Surgery.
