Abstract

Effective triage tools are indispensable for doctors to make a prompt decision for the treatment of multiple trauma patients in emergency departments (EDs). The Modified Early Warning Score (MEWS), National Early Warning Score (NEWS), standardized early warning score (SEWS), Modified Rapid Emergency Medicine Score (mREMS), and Revised Trauma Score (RTS) are five common triage tools proposed for trauma management. However, few studies have compared these tools in a multiple trauma cohort and investigated the influence of nighttime admission on the performance of these tools. This retrospective study was aimed at evaluating and comparing the performance of MEWS, NEWS, SEWS, mREMS, and RTS for identifying the mortality risk and trauma severity of patients with multiple trauma admitted to the ED during the daytime and nighttime. Retrospective data were collected from the medical records of patients with multiple trauma admitted in the daytime or nighttime to calculate scores for each triage tool. Logistic regression analysis was conducted on each triage tool for identifying in-hospital mortality and severe trauma (injury severity score > 15) in the daytime and nighttime. The performance of the tools was evaluated and compared by calculating area under the receiver operating characteristic curve (AUROC) of the retrospective logistic model of each tool. We collected data for 1,818 admissions, including 1,070 daytime and 748 nighttime admissions. A comparison of performance for identifying in-hospital mortality between daytime and nighttime yielded the following results (AUROC): MEWS (0.95 vs. 0.93, p = 0.384), NEWS (0.95 vs. 0.94, p = 0.708), SEWS (0.95 vs. 0.94, p = 0.683), mREMS (0.94 vs. 0.92, p = 0.286), and RTS (0.93 vs. 0.93, p = 0.87). Similarly, a comparison of performance for identifying trauma severity between daytime and nighttime yielded the following results (AUROC): MEWS (0.78 vs. 0.78, p = 0.95), NEWS (0.8 vs. 0.8, p = 0.885), SEWS (0.78 vs. 0.78, p = 0.818), mREMS (0.75 vs. 0.69, p = 0.019), and RTS (0.75 vs. 0.74, p = 0.619). All five scores are excellent triage tools (AUROC ≥ 0.9) for identifying in-hospital mortality for both daytime and nighttime admissions. However, they have only moderate effectiveness (AUROC < 0.9) at identifying severe trauma. The NEWS is the best triage tool for identifying severe trauma for both daytime and nighttime admissions. The MEWS, NEWS, SEWS, and RTS exhibited no significant differences in performance for identifying in-hospital mortality or severe trauma during the daytime or nighttime. However, the mREMS was better at identifying severe trauma during the daytime.

Highlights

Multiple trauma is fatal due to sequelae such as traumatic shock, respiratory failure, or multiple organ dysfunction syndrome, leading to a high risk of mortality among patients
For identifying in-hospital mortality, our findings indicated that the Modified Early Warning Score (MEWS), National Early Warning Score (NEWS), standardized early warning score (SEWS), REM, and Revised Trauma Score (RTS) are all excellent triage tools (AUROC ≥ 0:9) for both daytime and nighttime admissions
Our results showed that the Modified Rapid Emergency Medicine Score (mREMS) performed better for daytime admissions than for nighttime admissions, while no significant differences were observed for the MEWS, NEWS, SEWS, or RTS (Table 5)

Summary

Introduction

Multiple trauma is fatal due to sequelae such as traumatic shock, respiratory failure, or multiple organ dysfunction syndrome, leading to a high risk of mortality among patients. The five scoring systems include fewer variables than anatomical systems, and the included variables can be measured and calculated rapidly without specialized medical equipment These five scoring systems include only 4-6 variables, in contrast to more complicated systems such as the Acute Physiology, Age, and Chronic Health Evaluation (APACHE) III score [10], which includes 17 variables. These five common triage tools have been widely used for risk-stratification measurement [11, 12], mortality risk prediction [5, 13–16], need of intensive care unit (ICU) admission [17–19], and trauma severity assessment [20, 21]
