基于PACS系统的CBL教学在医学影像诊断见习带教中的应用

Application of case based learning teaching method based on picture archiving and communication system in medical imaging internship

目的探讨基于影像存储与传输系统(PACS)的案例教学法(CBL)在医学影像诊断见习中的应用效果。方法选取2017年5～6月北京大学第三医院2013级临床方向八年制学生52名,按照随机数字表法分成实验组和对照组,每组26名。实验组采用基于PACS系统的CBL教学法,对照组采用传统教学法,两组均进行10学时的骨关节系统影像见习课。课后采用问卷调查两组学生对当前实施教学模式的评价,比较两组学生骨关节系统读片的考试成绩。结果实验组调查问卷中对教学模式的满意度,以及认为该模式有助于促进对理论知识的理解、提高自学及独立思考能力、培养交流及表达能力、提高临床思维能力、读片能力的评分均显著高于对照组(P<0.01),实验组的平均考试成绩高于对照组,差异均有统计学意义(P<0.05)。结论基于PACS系统的CBL教学法,是一种科学有效的教学模式,可以提高影像诊断见习课的教学效果。

Objective To evaluate the application effect of case based learning(CBL) teaching method based on picture archiving and communication system(PACS) in teaching medical imaging internship. Methods A total of 52 eight-year program clinical medicine direction students of class 2013 in Peking University Third Hospital from May to June 2017 were selected. They were randomly divided into experimental group and control group according to the random number table method, with 26 students in each group. The experimental group adopted the PACS-based CBL, while the control group adopted traditional teaching method. Ten hours’ teaching of bone and joint system imaging internship were performed in the two groups. After classe, questionnaire survey was used to investigate the students in the two groups evaluation on the present teaching mode. The results of bone and joint system reading examination were compared between the two groups. Results The quantitative scores of the satisfaction to the teaching mode, and the quantitative scores of the agreement that the mode contributed to promote the understanding of theoretical knowledge, improved the self-study and independent thinking ability, developed the communication and presentation skills, improved the clinical thinking ability, as well as the scores of the image reading ability, were significantly higher in the experimental group than the control group(P < 0.01). The average results of the experimental group was also higher than the control group,the differences were all statistically significant(P < 0.05). Conclusion The CBL teaching based on PACS is a scientific and effective teaching mode, which can improve the teaching effect of imaging internship.
