PACS结合PBL在医学影像学五年制本科生超声科临床教学中的作用探讨

Application of PACS combined with PBL in clinical teaching of ultrasound in 5-year medical imaging undergraduate

目的探讨图像存档和传输系统(PACS)结合以问题为导向的教学法(PBL)在影像专业五年制本科生超声科临床带教中的应用价值。方法选取2017年3~12月在我科实习的50名影像专业五年制本科生,将其随机分为对照组和研究组,每组各25名。研究组采取PACS结合PBL进行临床带教;对照组采取传统教学方法进行临床带教,比较两组出科考试的临床技能、理论知识结果及问卷调查结果。结果研究组临床技能及理论知识考核成绩均高于对照组,差异均有统计学意义(均P<0.05);两组问卷调查显示,研究组自主学习能力、培养临床思维能力、查阅文献及资料能力等均明显优于对照组,差异均有统计学意义(均P<0.05)。结论PACS结合PBL教学模式有助于提高影像专业学生的临床技能及理论知识,且教学效果好。

Objective To explore the application value of picture archiving and communication system(PACS)combined with problem-based learning(PBL)in clinical teaching of ultrasound for 5-year undergraduates majoring in imaging.Methods Fifty 5-year undergraduates who were practicing in the department of ultrasound from March to December 2017 were randomly divided into control group and observation group with 25 students in each group.In the observation group,PACS and PBL were used for clinical teaching,while in the control group,the traditional teaching method was used,and the results of clinical skills,theoretical knowledge and questionnaire survey were compared between the two groups.Results The examination scores of clinical skills and theoretical knowledge in the observation group were higher than those in the control group,and the difference was statistically significant(both P<0.05).Questionnaire survey of the two groups showed that students in the observation group were better than those in the control group in autonomous learning ability,clinical thinking ability,literature and data access ability,etc.(all P<0.05).Conclusion The combination of PACS and PBL teaching mode is helpful to improve the clinical skills and theoretical knowledge in medical imaging undergraduate,and the teaching effect is good.
