The study aimed to develop an objectified Korean Triage and Acuity Scale (OTAS) that can objectively and quickly classify severity, as well as a simple age-adjusted OTAS (S-OTAS) that reflects age and evaluate its usefulness.
A retrospective analysis was performed of all adult patients who had visited the emergency department at three teaching hospitals. Sex, systolic blood pressure, diastolic blood pressure, pulse rate, respiratory rate, body temperature, O saturation, and consciousness level were collected from medical records. The OTAS was developed with objective criterion and minimal OTAS level, and S-OTAS was developed by adding the age variable. For usefulness evaluation, the 30-day mortality, the rates of computed tomography scan and emergency procedures were compared between Korean Triage and Acuity Scale (KTAS) and OTAS.
A total of 44402 patients were analyzed. For 30-day mortality, S-OTAS showed a higher area under the curve (AUC) compared to KTAS (0.751 vs. 0.812 for KTAS and S-OTAS, respectively, <0.001). Regarding the rates of emergency procedures, AUC was significantly higher in S-OTAS, compared to KTAS (0.807 vs. 0.830, for KTAS and S-OTAS, respectively, =0.013).
S-OTAS showed comparative usefulness for adult patients visiting the emergency department as a triage tool compared to KTAS.
本研究旨在开发一种客观的韩国分诊和 acuity 量表（OTAS），以客观、快速地对严重程度进行分类，以及一种简单的年龄调整 OTAS（S-OTAS），以反映年龄并评估其有用性。
对三家教学医院急诊科就诊的所有成年患者进行回顾性分析。从病历中收集性别、收缩压、舒张压、脉搏率、呼吸率、体温、O 饱和度和意识水平。OTAS 是根据客观标准和最小 OTAS 水平开发的，S-OTAS 是通过添加年龄变量开发的。为了评估有用性，比较了韩国分诊和 acuity 量表（KTAS）和 OTAS 之间的 30 天死亡率、计算机断层扫描和急诊程序的发生率。
共分析了 44402 例患者。对于 30 天死亡率，S-OTAS 的曲线下面积（AUC）高于 KTAS（S-OTAS 和 KTAS 分别为 0.751 和 0.812，<0.001）。关于急诊程序的发生率，S-OTAS 的 AUC 明显高于 KTAS（S-OTAS 和 KTAS 分别为 0.807 和 0.830，=0.013）。
与 KTAS 相比，S-OTAS 作为一种分诊工具，对急诊科就诊的成年患者具有相当的有用性。
