There is no standardized curriculum currently available at most institutions for establishing procedural competency in trainees performing cervicocerebral angiography. The purpose of this study was to evaluate a simple learning program to supplement the teaching of basic cervicocerebral angiography.
An 11-session interactive curriculum was implemented covering anatomic, clinical, and radiographic topics for the novice cervicocerebral angiographer. The target learner was the neuroradiology fellow. Data were gathered regarding fellow comfort level on topics relating to cervicocerebral angiography by using a 5-point Likert scale. Improvement in scores on knowledge-based questions after completion of the curriculum was calculated (McNemar test). Trainee-perceived utility of the program was also recorded by using a 5-point Likert scale. Focus sessions were held at the completion of the curriculum to gather feedback regarding the strengths and weaknesses of the program from participants.
Ten subjects were enrolled in this pilot study for 3 years. Topics where participants reported a poor initial comfort level (4 or higher) included selection of injection rates and volumes and reformation of reverse-curve catheters. Trainees demonstrated a statistically significant change in the distribution of scores of 29.3% (49.4%-78.7% correct response rate, P < .0001). The average perceived utility was 1.5 (1 = most useful, 5 = least useful).
This simple learning program was a useful adjunct to the training of fellows in diagnostic cervicocerebral angiography, resulting in quantitative improvements in knowledge.
目前大多数机构都没有标准化的课程来培养接受过培训的学员在进行颈内动脉造影时的操作能力。本研究的目的是评估一个简单的学习计划,以补充基础颈内动脉造影的教学。
实施了一个包含 11 个环节的互动课程,涵盖了初学者进行颈内动脉造影的解剖学、临床和放射学方面的内容。目标学习者是神经放射科住院医师。使用 5 分制 Likert 量表收集关于颈内动脉造影相关主题的住院医师舒适程度的数据。计算课程完成后知识基础问题的得分提高情况(McNemar 检验)。还使用 5 分制 Likert 量表记录了学员对该计划的实用性的看法。课程结束时举行了焦点会议,以从参与者那里收集有关该计划优缺点的反馈。
本研究在 3 年内招募了 10 名学员参加该试点研究。参与者报告初始舒适度水平较差(4 或更高)的主题包括注射率和注射量的选择以及反向曲线导管的再成型。学员的分数分布发生了统计学上显著的变化,从 29.3%(49.4%-78.7%正确回答率,P<.0001)。平均感知效用为 1.5(1=最有用,5=最没用)。
这个简单的学习计划是诊断性颈内动脉造影培训的有用辅助手段,可定量提高知识水平。
