Abstract

Purpose: Coronary anastomosis is the most key factor to accomplish coronary artery bypass grafting, which is one of the largest areas in cardiovascular surgery. Although we have organized on-site simulator training courses of coronary anastomosis using BEAT YOUCAN, it became difficult to continue it because of COVID-19. Therefore, we established a real-time evaluation sheet instead of an Objective Structured Assessment of Technical Skills (OSATS) evaluation sheet. The purposes of this study was to develop the real-time assessment system and to prove the correlation between the score obtained by the OSATS and the score obtained by the real-time evaluation system.

Subjects and methods: A total of 22 videos from the qualifying round of real-time coronary anastomosis competition evaluated by both the modified OSATS and the real-time evaluation system were utilized in this study. The global rating score of OSATS was compared with the global rating score of real-time evaluation system.

Results: When examined the relationship between the OSATS total score and the real-time total score, there was a significant correlation (R = 0.752, p <0.001). The OSATS general definition score and the real-time total score also showed a strong correlation (R = 0.733, p <0.001).

Conclusions: We developed a real-time assessment sheet to evaluate coronary anastomosis. This assessment sheet had a good correlation with the OSATS evaluation sheet.

一种新的冠状动脉吻合技术实时评估方法。
目的:冠状动脉吻合是完成冠状动脉搭桥术的最关键因素,而冠状动脉搭桥是心血管外科最大的领域之一。尽管我们使用BEAT YOUCAN组织了冠状动脉吻合的现场模拟训练课程,但由于新冠肺炎,很难继续进行。因此,我们建立了一个实时评估表,而不是目标结构化技术技能评估(OSATS)评估表。本研究的目的是开发实时评估系统,并证明OSATS获得的分数与实时评估系统获得的分数之间的相关性。受试者和方法:本研究共使用了22段来自实时冠状动脉吻合比赛资格赛的视频,这些视频通过改进的OSATS和实时评估系统进行了评估。将OSATS的全球评分与实时评估系统的全球评分进行比较。结果:OSATS总分与实时总分之间存在显著相关性(R=0.752,p)。结论:我们开发了一个实时评估表来评估冠状动脉吻合,该评估表与OSATS评估表具有良好的相关性。
