摘要
背景增强现实(AR)通过多种设备将计算机生成的内容叠加到真实世界的环境中,被广泛应用于多个培训领域。其在血管外科教育中的应用尚待正式研究。本研究旨在评估通过 HoloLens2 头戴式显示器技术形式的 AR 增强的血管吻合术技能远程教学与传统的面对面技能教学的可行性和有效性。远程培训师通过 HoloLens2 在学员视野中叠加视频、手势和图像来教授技能。方法28 名学员在人工血管上进行端到端血管吻合术前评估。他们被随机分配到AR组或面对面组,并接受了两节教学课程。他们被要求完成课后反馈表和评估(录像并匿名)。视频由两名盲人独立评估员使用技术技能客观结构化评估(OSATS)评分法进行评分。结果干预后,两组学员的 OSATS 评分均有整体提高,面授组提高了 7.083 分,AR 组提高了 8.275 分。进行了独立 t 检验,P 值为 0.422,表明当面教学与通过 AR 进行的技能教学相比,OSATS 分数的变化没有显著的统计学差异。在血管外科技能培训中使用 AR 还有很大的发展空间。
A comparison between augmented reality and traditional in-person teaching for vascular anastomotic surgical skills training
Background
Augmented reality (AR) superimposes computer-generated content to a real-world environment through multitudinous devices, and is used across multiple training fora. Its use in vascular surgery education is yet to be formally investigated. The aim is to assess feasibility and effectiveness of remote teaching of vascular anastomosis skills enhanced by AR in the form of the HoloLens2 Head-Mounted Display technology with traditional in-person skills teaching. A remote trainer used video, gestures and images superimposed over participants' field of vision via the HoloLens2 to teach the skills.
Methods
Twenty-eight participants underwent a preassessment performing an end-to-end vascular anastomosis on an artificial vessel. They were allocated randomly to an AR or in-person group, and underwent two teaching sessions. Individuals were asked to complete a postsession feedback form and assessment (video recorded and anonymized). The videos were marked by two blinded, independent assessors using the Objective Structured Assessment of Technical Skills (OSATS) scoring.
Results
There was an overall improvement in both cohorts in OSATS score after the intervention by +7.083 in the in-person group and +8.275 in the AR. Independent t test was performed and a P value of .422 was obtained, indicating no statistically significant difference in the change in OSATS scores when comparing the skills teaching received in-person with that through AR.
Conclusions
Remote teaching enhanced by AR is feasible and effective for the teaching of vascular surgical anastomosis skills and noninferior to in-person teaching. There is scope for development of the use of AR in vascular surgical skills training.
