基于PACS系统的CBL教学法在超声医学科住院医师规范化培训中的初步应用

Preliminary Application of CBL Teaching Method Based on PACS System in Standardized Training for Residents in Ultrasound Medicine

目的:在初步构建的基于图像存储和传输系统(PACS)的临床超声病例库的基础上,探讨应用案例教学法(CBL)在超声医学住院医师规范化培训教学中的应用价值。方法:将2020年于我院进行超声医学科住院医师规范化培训的40名学员分为对照组和试验组,分别应用传统的带教方法和基于PACS系统的CBL教学法进行教学。通过超声理论知识考核、临床思维与决策考核及问卷调查的形式,评价试验组和对照组学员的教学效果和带教老师的教学满意度。结果:试验组在超声理论知识成绩、超声临床思维与决策能力考试的成绩均显著高于对照组(P<0.05),试验组在超声理论学习和学员之间交流和自我语言表达能力等方面的评分均显著高于对照组(P<0.05)。结论:基于PACS系统的CBL教学法不仅可以有效提高学员的临床思维决策能力、语言表达能力,还可以提高老师的带教水平及学员的满意度。

Objective:Based on the preliminary construction of a clinical ultrasound case library based on the Picture Archiving and Communication System(PACS),this study aimed to explore the application value of Case-Based Learning(CBL)in standardized training for residents in ultrasound medicine.Methods:A total of 40 residents undergoing standardized training in the ultrasound medicine department of our hospital in 2020 were divided into experimental and control groups.The traditional mentoring method and the CBL teaching method based on the PACS system were applied for teaching.The teaching effectiveness of the two groups and the teaching satisfaction of the mentoring teachers were evaluated through assessments of ultrasound theoretical knowledge,clinical thinking and decision-making,and questionnaire surveys.Results:The experimental group showed significantly higher scores than the control group in ultrasound theoretical knowledge and ultrasound clinical thinking and decision-making exams(P<0.05).The experimental group also scored significantly higher in ultrasound theoretical learning,communication between students,and self-expression abilities compared to the control group(P<0.05).Conclusion:The CBL teaching method based on the PACS system can effectively improve the clinical thinking and decision-making abilities,as well as the language expression abilities of the residents.It can also enhance the mentoring level of teachers and the satisfaction of the residents.
