We sought to develop a standardized curriculum capable of assessing key competencies in Interventional Neuroradiology by the use of models and simulators in an objective, quantitative, and efficient way. In this evaluation we analyzed the associations between the practical experience, theoretical knowledge, and the skills lab performance of interventionalists.
We evaluated the endovascular skills of 26 participants of the Advanced Course in Endovascular Interventional Neuroradiology of the European Society of Neuroradiology with a set of three tasks (aneurysm coiling and thrombectomy in a virtual simulator and placement of an intra-aneurysmal flow disruptor in a flow model). Practical experience was assessed by a survey. Participants completed a written and oral examination to evaluate theoretical knowledge. Bivariate and multivariate analyses were performed.
In multivariate analysis knowledge of materials and techniques in Interventional Neuroradiology was moderately associated with skills in aneurysm coiling and thrombectomy. Experience in mechanical thrombectomy was moderately associated with thrombectomy skills, while age was negatively associated with thrombectomy skills. We found no significant association between age, sex, or work experience and skills in aneurysm coiling.
Our study gives an example of how an integrated curriculum for reasonable and cost-effective assessment of key competences of an interventional neuroradiologist could look. In addition to traditional assessment of theoretical knowledge practical skills are measured by the use of endovascular simulators yielding objective, quantitative, and constructive data for the evaluation of the current performance status of participants as well as the evolution of their technical competency over time.
我们试图开发一种标准化课程，能够通过使用模型和模拟器，以客观、定量和高效的方式评估介入神经放射学的关键能力。在本评估中，我们分析了介入医生的实践经验、理论知识与技能实验室表现之间的关联。
我们使用一组三项任务（在虚拟模拟器中进行动脉瘤栓塞和血栓切除术，以及在血流模型中放置动脉瘤内血流干扰装置）评估了26名参加欧洲神经放射学会血管内介入神经放射学高级课程的学员的血管内技能。通过一项调查评估实践经验。参与者完成了书面和口头考试以评估理论知识。进行了双变量和多变量分析。
在多变量分析中，介入神经放射学中材料和技术的知识与动脉瘤栓塞和血栓切除术技能中度相关。机械血栓切除术的经验与血栓切除术技能中度相关，而年龄与血栓切除术技能呈负相关。我们发现年龄、性别或工作经验与动脉瘤栓塞技能之间无显著关联。
我们的研究给出了一个示例，展示了一个用于合理且经济高效地评估介入神经放射学家关键能力的综合课程可能是什么样的。除了对理论知识进行传统评估外，还通过使用血管内模拟器来衡量实践技能，从而为评估参与者的当前表现状态以及他们技术能力随时间的演变产生客观、定量和有建设性的数据。
