The debriefing process during simulation-based education has been poorly studied despite its educational importance. Videotape feedback is an adjunct that may enhance the impact of the debriefing and in turn maximize learning. The purpose of this study was to investigate the value of the debriefing process during simulation and to compare the educational efficacy of two types of feedback, oral feedback and videotape-assisted oral feedback, against control (no debriefing).
Forty-two anesthesia residents were enrolled in the study. After completing a pretest scenario, participants were randomly assigned to receive no debriefing, oral feedback, or videotape-assisted oral feedback. The debriefing focused on nontechnical skills performance guided by crisis resource management principles. Participants were then required to manage a posttest scenario. The videotapes of all performances were later reviewed by two blinded independent assessors who rated participants' nontechnical skills using a validated scoring system.
Participants' nontechnical skills did not improve in the control group, whereas the provision of oral feedback, either assisted or not assisted with videotape review, resulted in significant improvement (P < 0.005). There was no difference in improvement between oral and video-assisted oral feedback groups.
Exposure to a simulated crisis without constructive debriefing by instructors offers little benefit to trainees. The addition of video review did not offer any advantage over oral feedback alone. Valuable simulation training can therefore be achieved even when video technology is not available.
尽管基于模拟的教育中的总结过程具有重要的教育意义,但对其研究甚少。录像反馈是一种辅助手段,可能会增强总结的效果,进而使学习效果最大化。本研究的目的是探讨模拟过程中总结过程的价值,并比较两种反馈类型(口头反馈和录像辅助口头反馈)与对照组(无总结)的教育效果。
42名麻醉住院医师参与了本研究。在完成一个预测试场景后,参与者被随机分配接受无总结、口头反馈或录像辅助口头反馈。总结聚焦于在危机资源管理原则指导下的非技术技能表现。然后要求参与者处理一个后测试场景。所有表现的录像随后由两名 blinded 独立评估者进行审查,他们使用经过验证的评分系统对参与者的非技术技能进行评分。
对照组参与者的非技术技能没有提高,而提供口头反馈(无论是否有录像审查辅助)都导致了显著提高(P < 0.005)。口头反馈组和录像辅助口头反馈组在提高方面没有差异。
在没有教员进行建设性总结的情况下接触模拟危机对学员益处不大。添加录像审查与单独的口头反馈相比没有任何优势。因此,即使没有视频技术,也可以实现有价值的模拟培训。
