Over the last decade, the United States has witnessed an increase in mass casualty incidents (MCIs). The outcome of an MCI depends upon hospital preparedness, yet many hospitals are unfamiliar with their facility MCI procedure. Educational training drills may be one method to improve staff knowledge of policy and procedure.
This study aimed to improve knowledge gained through educational MCI mini drills of institutional mass casualty policy and procedure in surgery department staff at a level II trauma center.
A pre-/posttest design was utilized. The hospital implemented MCI mini training drills as a quality improvement project using Plan-Do-Study-Act iterative cycles with prospective data collection. Knowledge scores were measured using a 12-item surgery department MCI policy and procedure questionnaire that was developed by the author and leadership.
A one-way analysis of covariance analysis in participants that mini drilled more than once indicated significant effect on mean cycle score differences among three cycles F(2,21) = 12.96, p = .00. Multiple comparison using Games-Howell indicated the mean score for Cycle 4 (M = 96.15, SD = 6.54) was significantly different from Cycle 3 (M = 59.71, SD = 25.15). Gender, shift, and credentials of participants influenced knowledge improvement.
Implementation of hospital MCI mini drills improved staff knowledge of institutional mass casualty policy and procedure in the surgery department and may be applied to surgery departments with similar policy, procedure, and participant characteristics. Hospital mass casualty response education and preparation is essential to saving lives.
在过去的十年中，美国见证了大规模伤亡事件（MCIs）的增加。MCI 的结果取决于医院的准备情况，但许多医院对其设施 MCI 程序不熟悉。教育培训演练可能是提高员工了解政策和程序的知识的一种方法。
本研究旨在通过对二级创伤中心外科部门工作人员进行机构大规模伤亡政策和程序的教育性 MCI 迷你演练，提高他们通过教育获得的知识。
采用预/后测试设计。医院使用计划-执行-研究-行动迭代循环作为质量改进项目，同时进行前瞻性数据收集，实施 MCI 迷你培训演练。知识得分通过作者和领导层开发的 12 项外科部门 MCI 政策和程序问卷进行测量。
对多次进行迷你演练的参与者进行单向方差分析协方差分析表明，三个周期之间的平均周期得分差异存在显著影响 F(2,21) = 12.96，p =.00。使用 Games-Howell 进行的多重比较表明，第 4 周期的平均得分（M = 96.15，SD = 6.54）与第 3 周期（M = 59.71，SD = 25.15）有显著差异。参与者的性别、班次和证书影响了知识的提高。
医院 MCI 迷你演练的实施提高了外科部门工作人员对机构大规模伤亡政策和程序的知识，并且可以应用于具有类似政策、程序和参与者特征的外科部门。医院大规模伤亡应急教育和准备对于拯救生命至关重要。
