Video feedback, particularly with a head-mounted camera, has previously been described as a useful debriefing tool in well-funded health systems but has never been performed in a low-resource environment. The purpose of this randomized, intervention-controlled study is to evaluate the feasibility of using video feedback with a head-mounted camera during intestinal anastomosis simulation training in a low-resource setting.
This study recruited 14 first-year surgery residents in Senegal, who were randomized into control and camera groups. Both groups received reading materials and video lectures before performing a manual end-to-end intestinal anastomosis using a synthetic model. The control group received oral feedback, while the camera group's first attempt was recorded, reviewed, and discussed before the second attempt. The primary outcomes were OSATS scores and completion time.
There were no significant demographic differences between the groups. Both groups showed significant improvement in OSATS scores from the first to the second attempt (control group: p = 0.002; camera group: p = 0.0021). The camera group demonstrated a significant reduction in completion time on the second attempt (p = 0.0038), unlike the control group (p = 0.17). Both groups reported increased confidence in performing the task (control group: p = 0.003; camera group: p = 0.0029) and had positive perceptions of the workshop's effectiveness.
This pilot study suggests that video feedback with a head-mounted camera is feasible and effective for debriefing during intestinal anastomosis simulation training in a low-resource setting, offering a low-cost, effective way to enhance technical skills. Further research with larger sample sizes is recommended to validate these findings and explore long-term impacts on surgical proficiency.
视频反馈，尤其是头戴式摄像头的反馈，此前在资金充足的医疗系统中被描述为一种有用的汇报工具，但从未在资源匮乏的环境中进行过。这项随机、干预对照研究的目的是评估在资源匮乏的环境中，在肠道吻合模拟训练期间使用头戴式摄像头进行视频反馈的可行性。
本研究招募了14名塞内加尔的一年级外科住院医师，他们被随机分为对照组和摄像头组。两组在使用合成模型进行手工端端肠道吻合之前都收到了阅读材料和视频讲座。对照组接受口头反馈，而摄像头组的第一次尝试被记录下来，在第二次尝试之前进行回顾和讨论。主要结果是OSATS评分和完成时间。
两组之间在人口统计学上没有显著差异。两组从第一次尝试到第二次尝试的OSATS评分均有显著提高（对照组：p = 0.002；摄像头组：p = 0.0021）。与对照组不同（p = 0.17），摄像头组在第二次尝试时完成时间显著缩短（p = 0.0038）。两组都报告在执行任务时信心增强（对照组：p = 0.003；摄像头组：p = 0.0029），并且对研讨会的有效性有积极的看法。
这项试点研究表明，在资源匮乏的环境中，头戴式摄像头的视频反馈在肠道吻合模拟训练期间进行汇报是可行且有效的，提供了一种低成本、有效的提高技术技能的方法。建议进行更大样本量的进一步研究以验证这些发现，并探索对手术熟练程度的长期影响。
