Debriefing is a critical component of effective simulation-based medical education. The optimal format in which to conduct debriefing is unknown. The use of video review has been promoted as a means of enhancing debriefing, and video-assisted debriefing is widely used in simulation training. Few empirical studies have evaluated the impact of video-assisted debriefing, and the results of those studies have been mixed. The objective of this study was to compare the effectiveness of video-assisted debriefing to oral debriefing alone at improving performance in neonatal resuscitation.
Thirty residents, divided into 15 teams of 2 members each, participated in the study. Each team completed a series of 3 neonatal resuscitation simulations. Each simulation was followed by a facilitated debriefing. Teams were randomly assigned to receive either oral debriefing alone or video-assisted debriefing after each simulation. Objective measures of performance and times to complete critical tasks in resuscitation were evaluated by blinded video review on the first (pretest) and the third (posttest) simulations using a previously validated tool.
Overall neonatal resuscitation performance scores improved in both groups [mean (SD), 83% (14%) for oral pretest vs. 91% (7%) for oral posttest (P = 0.005); 81% (16%) for video pretest vs. 93% (10%) for video posttest (P < 0.001)]. There was no difference in performance scores between the 2 groups on either the pretest or posttest [overall posttest scores, 91.3% for oral vs. 93.4% for video (P = 0.59)]. Times to complete the critical tasks of resuscitation also did not differ significantly between the 2 study groups. The educational effect of the video-assisted debriefing versus oral debriefing alone was small (d = 0.08).
Using this study design, we failed to show a significant educational benefit of video-assisted debriefing. Although our results suggest that the use of video-assisted debriefing may not offer significant advantage over oral debriefing alone, exactly why this is the case remains obscure. Further research is needed to define the optimal role of video review during simulation debriefing in neonatal resuscitation.
汇报是基于模拟的医学教育的重要组成部分。进行汇报的最佳形式尚不清楚。视频审查已被推广为增强汇报的一种手段,视频辅助汇报在模拟培训中被广泛使用。很少有实证研究评估视频辅助汇报的影响,这些研究的结果也不一致。本研究的目的是比较视频辅助汇报与单独口头汇报在改善新生儿复苏绩效方面的效果。
30 名住院医师分为 15 个 2 人小组参加了研究。每个小组完成了一系列 3 次新生儿复苏模拟。每次模拟后都进行了促进性汇报。团队被随机分配在每次模拟后接受单独的口头汇报或视频辅助汇报。使用以前验证过的工具,通过盲法视频回顾评估第一次(预测试)和第三次(后测试)模拟的客观表现测量和完成复苏关键任务的时间。
两组的新生儿复苏整体表现评分均有所提高[口头预测试 83%(14%),口头后测试 91%(7%)(P = 0.005);视频预测试 81%(16%),视频后测试 93%(10%)(P < 0.001)]。两组在前测或后测的表现评分之间没有差异[总体后测评分,口头 91.3%对视频 93.4%(P = 0.59)]。复苏关键任务的完成时间也没有明显差异两组之间。视频辅助汇报与单独口头汇报相比,其教育效果较小(d = 0.08)。
使用本研究设计,我们未能显示视频辅助汇报具有显著的教育益处。尽管我们的结果表明,使用视频辅助汇报可能没有明显优于单独口头汇报,但具体原因尚不清楚。需要进一步研究来确定视频审查在新生儿复苏模拟汇报中的最佳作用。
