Our objective was to measure the impact of a basic microsurgery training course on trainees' confidence and workload in performing microsurgery.
A prospective study of participants in an accredited 5-day microsurgery course over a 3-month period. The confidence and workload of the participants were assessed after the first and final day. The workload was assessed using the validated NASA Task Load Index composed of 6 subscales scored on a 20-point visual analog scale (VAS). Confidence was assessed over 5 dimensions on a 5-point VAS for anastomosis performance, vessels preparation, knot tying, training effectiveness, and future practice of microsurgery.
A total of 31 participants completed the study with 55% reporting some previous microsurgery experience. All confidence dimensions improved significantly after completing the course, regardless of prior experience (p<0.01). Those with prior experience started and finished the course at higher confidence levels in anastomosis performance and vessel preparation than the non-experienced group (p<0.05). Overall workload showed a downward trend (improvement) at the end of the course, but no significant changes in the experienced and non-experienced groups (p>0.05). Most participants scored above the 50% "sustainability threshold" for mental demand, both before (71%) and after the course (73%), however, perceived physical demand significantly reduced, p = 0.01.
The microsurgery course teaches fundamental skills and principles; therefore, it has merit in those who will utilize these skills in their future practice. Although there is increased confidence in skill acquisition, the impact on perceived workload during a short 5-day basic microsurgery course did not significantly change.
我们的目的是衡量基础显微外科培训课程对学员进行显微手术的信心和工作量的影响。
在 3 个月的时间内，对参加为期 5 天的认证显微外科课程的参与者进行前瞻性研究。在第 1 天和最后一天评估参与者的信心和工作量。使用经过验证的 NASA 任务负荷指数（由 6 个分量表组成，在 20 分制的视觉模拟量表（VAS）上评分）评估工作量。信心通过 5 点 VAS 评估吻合性能、血管准备、打结、培训效果和未来进行显微手术的 5 个维度进行评估。
共有 31 名参与者完成了这项研究，其中 55%的人报告有过一些显微外科经验。无论是否有先前的经验，所有信心维度在完成课程后都显著提高（p<0.01）。有先前经验的人在吻合性能和血管准备方面开始和结束课程的信心水平高于无经验组（p<0.05）。总体工作量在课程结束时呈下降趋势（有所改善），但在有经验和无经验组中没有显著变化（p>0.05）。大多数参与者在心理需求方面的得分均高于 50%的“可持续性阈值”，无论是在课程之前（71%）还是之后（73%），但感知到的体力需求明显降低，p=0.01。
该显微外科课程教授基本技能和原则；因此，对于那些将在未来实践中利用这些技能的人来说，该课程是有价值的。虽然在技能获得方面信心增强，但在为期 5 天的基础显微外科课程中，对感知工作量的影响没有显著改变。
