The effectiveness of e-learning for reporting of x-ray-findings in a prospective, randomized trial was tested.
Twenty advanced medical students were randomized into two groups. The test group practiced 4-6 hours with the newly developed software, the control group used conventional learning material. Afterwards, a test was carried out including 30 pathologic x-ray films that were randomly spread through 200 non-pathologic images. The required time, the number of correctly appraised images and the frequency of falsely suspected pathologies were recorded. In addition, we asked for an assessment of the own capabilities in evaluating x-ray films and of passing the radiology training.
The test group showed a markedly improved efficiency in comparison to the control group in all parameters. The required time was 57.4% shorter than in the control group (p < 0.05), 18.3% more cases were evaluated correctly (p < 0.05). The frequency of falsely suspected pathologies decreased by 61% (p < 0.05). There was no significant correlation of the objective abilities of a student with his/her self-assessment or of passing the radiology course.
This study shows that an effective standardized training of practical skills by means of e-learning is feasible and reasonable.
在一项前瞻性随机试验中,对电子学习用于报告X线检查结果的有效性进行了测试。
20名高年级医学生被随机分为两组。试验组使用新开发的软件练习4 - 6小时,对照组使用传统学习材料。之后,进行了一项测试,包括30张病理X线片,这些片子随机分布在200张非病理图像中。记录所需时间、正确评估的图像数量以及错误怀疑病变的频率。此外,我们还要求对学生自己评估X线片的能力以及通过放射学培训的情况进行评价。
试验组在所有参数方面与对照组相比效率明显提高。所需时间比对照组短57.4%(p < 0.05),正确评估的病例多18.3%(p < 0.05)。错误怀疑病变的频率降低了61%(p < 0.05)。学生的客观能力与其自我评估或通过放射学课程之间没有显著相关性。
本研究表明,通过电子学习进行有效的标准化实践技能培训是可行且合理的。
