The objective of this study was to determine if modification of the Simple Triage and Rapid Treatment (START) system by the addition of an Orange category, intermediate between the most critically injured (Red) and the non-critical, non-ambulatory injured (Yellow), would reduce over- and under-triage rates in a simulated mass-casualty incident (MCI) exercise.
A computer-simulation exercise of identical presentations of an MCI scenario involving a 2-train collision, with 28 case scenarios, was provided for triaging to two groups: the Fire Department of the City of New York (FDNY; n=1,347) using modified START, and the Emergency Medical Services (EMS) providers from the Eagles 2012 EMS conference (Lafayette, Louisiana USA; n=110) using unmodified START. Percent correct by triage category was calculated for each group. Performance was then compared between the two EMS groups on the five cases where Orange was the correct answer under the modified START system.
Overall, FDNY-EMS providers correctly triaged 91.2% of cases using FDNY-START whereas non-FDNY-Eagles providers correctly triaged 87.1% of cases using unmodified START. In analysis of the five Orange cases (chest pain or dyspnea without obvious trauma), FDNY-EMS performed significantly better using FDNY-START, correctly triaging 86.3% of cases (over-triage 1.5%; under-triage 12.2%), whereas the non-FDNY-Eagles group using unmodified START correctly triaged 81.5% of cases (over-triage 17.3%; under-triage 1.3%), a difference of 4.9% (95% CI, 1.5-8.2).
The FDNY-START system may allow providers to prioritize casualties using an intermediate category (Orange) more properly aligned to meet patient needs, and as such, may reduce the rates of over-triage compared with START. The FDNY-START system decreases the variability in patient sorting while maintaining high field utility without needing computer assistance or extensive retraining. Comparison of triage algorithms at actual MCIs is needed; however, initial feedback is promising, suggesting that FDNY-START can improve triage with minimal additional training and cost.
本研究的目的是确定在简单分类与快速治疗(START)系统中增加一个橙色类别(介于伤势最重的红色类别和伤势不严重、无法行走的黄色类别之间)是否会降低模拟大规模伤亡事件(MCI)演练中的过度分类和分类不足率。
提供了一个计算机模拟演练,内容为涉及两列火车相撞的相同MCI场景呈现,有28个病例场景,供两组进行分类:使用改良START的纽约市消防局(FDNY;n = 1347),以及来自2012年老鹰急救医疗服务会议(美国路易斯安那州拉斐特;n = 110)的使用未改良START的急救医疗服务(EMS)提供者。计算每组按分类类别划分的正确百分比。然后在改良START系统下橙色为正确答案的五个病例上比较两个EMS组的表现。
总体而言,FDNY的EMS提供者使用FDNY-START正确分类了91.2%的病例,而来自老鹰急救医疗服务会议的非FDNY提供者使用未改良START正确分类了87.1%的病例。在对五个橙色病例(无明显创伤的胸痛或呼吸困难)的分析中,FDNY的EMS使用FDNY-START表现明显更好,正确分类了86.3%的病例(过度分类1.5%;分类不足12.2%),而使用未改良START的非FDNY-老鹰组正确分类了81.5%的病例(过度分类17.3%;分类不足1.3%),差异为4.9%(95% CI,1.5 - 8.2)。
FDNY-START系统可能使提供者能够使用一个更符合患者需求的中间类别(橙色)更恰当地对伤亡人员进行优先排序,因此与START相比,可能会降低过度分类率。FDNY-START系统在不需要计算机辅助或大量再培训的情况下,减少了患者分类的变异性,同时保持了较高的现场实用性。需要在实际的MCI中对分类算法进行比较;然而,初步反馈很有前景,表明FDNY-START只需最少的额外培训和成本就能改善分类。
