The Neurology and Neurosurgery Interest Group (NANSIG) neurosurgical skills workshop is novel in teaching neurosurgical skills solely to medical students and foundation trainees in the UK. The aim is to offer an affordable option for a high-fidelity simulation course enabling students to learn and practise specific neurosurgical skills in a safe, supervised environment.
A 10-delegate cohort was quantitatively assessed at the NANSIG neurosurgical skills workshop. Two assessors used a novel modified Objective Structured Assessment of Technical Skills (mOSATS) assessment tool, comprising 5 domains ranked according to a 5-point scale to rate delegates' ability to create a burr hole. Qualitative data from previous workshops were collected, consisting of open-ended, closed-ended and 5-point Likert scale responses to pre- and post-workshop questionnaires. Data were analysed using SPSS® software.
Delegates scored a mean total of 62.1% (21.75/35) and 85.1% (29.8/35) in pre- and post-workshop assessments respectively revealing a statistically significant improvement. Regarding percentage of improvement, no significant difference was shown amongst candidates when comparing the number of neurosurgical cases observed and/or assisted in the past. There was no significant difference in the overall rating between the last two workshops (4.89 and 4.8 out of 5, respectively). One hundred percent of the attendees reported feeling more confident in assisting in theatre after the last two workshops.
We show that a simulation workshop cannot only objectively quantify the improvement of surgical skill acquisition but can also be beneficial regardless of the extent of prior experience.
神经外科学兴趣小组（NANSIG）神经外科技能工作坊是专门为英国的医学生和基础培训师教授神经外科技能的创新模式。其目的是提供一种经济实惠的高保真模拟课程选择，使学生能够在安全、受监督的环境中学习和练习特定的神经外科技能。
NANSIG 神经外科技能工作坊对 10 名代表学员进行了定量评估。两名评估员使用一种新颖的改良客观结构化评估技术（mOSATS）评估工具，该工具包含 5 个领域，根据 5 分制进行评分，以评估代表学员创建颅骨钻孔的能力。从前几轮工作坊收集了定性数据，包括预 workshop 和 post-workshop 问卷的开放性、封闭性和 5 分李克特量表回答。使用 SPSS®软件分析数据。
代表学员在 workshop 前和 workshop 后的评估中分别平均获得了 62.1%（21.75/35）和 85.1%（29.8/35）的分数，显示出统计学上的显著提高。关于百分比的提高，在比较过去观察和/或协助的神经外科手术数量方面，候选者之间没有显示出显著差异。最后两轮 workshop 的总体评分没有显著差异（分别为 4.89 和 4.8 分）。100%的与会者报告说，在最后两轮 workshop 后，他们在协助手术方面更有信心。
我们表明，模拟 workshop 不仅可以客观地量化手术技能获取的提高，而且无论之前的经验程度如何，都可以从中受益。
