Using the iPad application Explain Everything™, the authors created a "how to" video for stereotactic breast core biopsy to enhance their breast imaging curriculum. The objective was to show that video integration into residency training enhances resident learning.
A pretest was provided to all 40 radiology residents (postgraduate years 2-5) at the authors' institution. The test included 20 questions on the video content, 15 similarly framed control questions on material that was not included in the video, and four demographic questions. Questions were randomly ordered, and trainees were not informed that both types of questions were included. Residents were given one week to watch the 20-minute video before completing a posttest that included the same 35 content questions presented in a different order. Three logistical questions were also included. Results for the video and the control questions were analyzed separately and compared.
Thirty of 40 residents (75%) participated (6-9 residents each year). The average scores for the video and control pretest were 7.7 of 20 (38.5%) and 7.8 of 15 (52%) and for the posttest were 13.8 of 20 (69%) and 7.8 of 15 (52%), respectively. This corresponds to a 30.7% mean improvement on the video-content questions compared with a 0% improvement for the control test (P < .001). Similar improvement was seen across all four postgraduate years and on an individual level.
This instructional video added significantly to resident learning in the short term. Further study on the long-term role of educational videos in radiology residency training seems warranted.
作者使用iPad应用程序Explain Everything™制作了一段关于立体定向乳腺核心活检的“操作指南”视频，以完善他们的乳腺影像课程。目的是证明将视频融入住院医师培训可提高住院医师的学习效果。
对作者所在机构的所有40名放射科住院医师（研究生2至5年级）进行了一项预测试。测试包括20个关于视频内容的问题、15个关于视频未涵盖内容的类似框架的对照问题以及4个人口统计学问题。问题随机排序，且未告知受训者测试中包含两种类型的问题。住院医师有一周时间观看20分钟的视频，然后完成一项后测试，后测试包含以不同顺序呈现的相同35个内容问题。还包括3个后勤问题。分别分析并比较了视频问题和对照问题的结果。
40名住院医师中有30名（75%）参与（每年6至9名）。视频预测试和对照预测试的平均得分分别为20题中得7.7分（38.5%）和15题中得7.8分（52%），后测试的平均得分分别为20题中得13.8分（69%）和15题中得7.8分（52%）。这表明视频内容问题的平均提高率为30.7%，而对照测试的提高率为0%（P <.001）。在所有四个研究生年级以及个人层面都观察到了类似的提高。
这段教学视频在短期内显著提高了住院医师的学习效果。似乎有必要进一步研究教育视频在放射科住院医师培训中的长期作用。
