To elicit components of task complexity in emergency medical care, a study was conducted to contrast one medical procedure with two levels of task urgency in trauma patient resuscitation. Videotapes of actual resuscitation were reviewed to extract task characteristics of the procedure. Two levels of urgency were compared in the following areas: patient status, technical difficulty of tasks, the amount of available patient monitoring information, and the pace of work. Four components of task complexity in emergency medical care were identified: multiple and concurrent task, uncertainty, changing plans, and compressed work procedures and high workload. These components of task complexity pose challenges to team functions and can lead to problems in team coordination, such as conflicts in goals, tasks, and access to the patient. Training to increase explicit communications and improvements in the design of work procedures are necessary in order to meet the challenges of task complexity.
为了探究急诊医疗中任务复杂性的构成要素,开展了一项研究,对比了一种医疗程序在创伤患者复苏中的两种任务紧急程度。回顾了实际复苏的录像带,以提取该程序的任务特征。在以下方面对两种紧急程度进行了比较:患者状况、任务的技术难度、可获得的患者监测信息量以及工作节奏。确定了急诊医疗中任务复杂性的四个构成要素:多项并发任务、不确定性、计划变更以及紧凑的工作程序和高工作量。这些任务复杂性要素对团队功能构成挑战,并可能导致团队协调问题,如目标、任务及接近患者方面的冲突。为应对任务复杂性挑战,有必要进行培训以增强明确沟通,并改进工作程序的设计。
