This study aimed to identify the characteristics of patients injured by high-rotation cutting tools and the factors related to the severity of their injuries.
Adult patients (≥18 years), who presented to the emergency department (ED) after a high-rotation cutting tool injury and who were registered in the Korean Emergency Department-based Injury In-depth Surveillance (2011-2018) database, were included. Patients' demographic characteristics, injury-related factors, and Injury Severity Scores were collected. All included cases were categorized into two groups according to the tool that caused the injury: grinder versus nongrinder. The characteristics of the two groups were compared, and the factors associated with the severity of injuries were investigated.
Among 8,697 ED visits, 4,603 patients had been using a grinder and 4,094 had been using a nongrinder tool. The most frequently injured body part while using a grinder was the hand (46.4%), followed by the head (23.0%). While using a nongrinder tool, the most frequently injured body part was also the hand (64.0%), followed by the lower leg (11.4%). The odds of a severe injury were affected by patient age (odds ratio [OR], 1.024; 95% confidence interval [CI], 1.020-1.028) and using a grinder (OR, 2.073; 95% CI, 1.877-2.290). The odds of a severe injury using a grinder were higher in arm injuries (OR, 1.60; 95% CI, 1.40-1.83) and multiple-part injuries (OR, 1.998; 95% CI, 1.639-2.437). The odds of a severe injury using a grinder were lower for head injuries (OR, 0.481; 95% CI, 0.297-0.781).
Injuries from grinders were more likely to affect the head and neck than nongrinder injuries, despite the lower severity. The current lack of regulations on grinders in occupational safety and health standards warrants relevant legislation and the development of applicable safety equipment.
本研究旨在确定高转速切割工具致伤患者的特征以及与损伤严重程度相关的因素。
纳入成年患者（≥18岁），这些患者在高转速切割工具致伤后前往急诊科就诊，并被登记在韩国基于急诊科的损伤深度监测（2011 - 2018年）数据库中。收集患者的人口统计学特征、损伤相关因素和损伤严重程度评分。所有纳入病例根据致伤工具分为两组：磨床组与非磨床组。比较两组的特征，并调查与损伤严重程度相关的因素。
在8697次急诊科就诊病例中，4603例患者使用了磨床，4094例患者使用了非磨床工具。使用磨床时最常受伤的身体部位是手（46.4%），其次是头部（23.0%）。使用非磨床工具时，最常受伤的身体部位也是手（64.0%），其次是小腿（11.4%）。严重损伤的几率受患者年龄（比值比[OR]，1.024；95%置信区间[CI]，1.020 - 1.028）和使用磨床（OR，2.073；95% CI，1.877 - 2.290）影响。使用磨床导致严重损伤的几率在手臂损伤（OR，1.60；95% CI，1.40 - 1.83）和多部位损伤（OR，1.998；95% CI，1.639 - 2.437）中较高。使用磨床导致严重损伤的几率在头部损伤中较低（OR，0.481；95% CI，0.297 - 0.781）。
尽管磨床致伤的严重程度较低，但与非磨床致伤相比，磨床致伤更易影响头部和颈部。职业安全与健康标准中目前缺乏对磨床的相关规定，因此需要相关立法以及开发适用的安全设备。
