目的 探讨医疗3D打印数字云平台引入脊柱外科案例导向教学法(Case Based Learning,CBL)中的应用效果.方法 选取2022年9月—2023年1月中南大学湘雅医院脊柱外科学习的2019级68名本科生和2021级60名硕士生作为研究对象,按随机数表法将其分为本科生3D+CBL组(n=34)和CBL组(n=34),硕士生3D+CBL组(n=30)和CBL组(n=30).3D+CBL组将3D打印数字云平台引入CBL教学,CBL组仅采用CBL教学.比较两组的教学效果.结果 在本科生中,3D+CBL组笔试成绩优于CBL组,差异有统计学意义(P<0.05),但两组技能考核成绩比较,差异无统计学意义(P>0.05).在硕士生中,3D+CBL组笔试成绩和技能考核成绩均优于CBL组,差异有统计学意义(P均<0.05).本科及硕士3D+CBL组教学和满意评分均高于CBL组,差异有统计学意义(P均<0.05).结论 医疗3D打印数字云平台能够显著提升脊柱外科CBL教学的效果.
Application of Medical 3D Printing Digital Cloud Platform into Spine Sur-gery CBL Teaching
Objective To explore the application effect of case based learning(CBL)in spine surgery by introducing medical 3D printing digital cloud platform.Methods Sixty-eight undergraduates of grade 2019 and 60 master stu-dents of grade 2021 studying spinal surgery in Xiangya Hospital of Central South University from September 2022 to January 2023 were selected as the research objects,and were divided into undergraduate 3D+CBL group(n=34)and CBL group(n=34),master 3D+CBL group(n=30)and CBL group(n=30)according to random number table method.The 3D+CBL group introduced 3D printing digital cloud platform into CBL teaching,while the CBL group only ad-opted CBL teaching.The teaching effect of the two groups was compared.Results Among undergraduates,the written test score of the 3D+CBL group was better than that of the CBL group,the difference was statistically significant(P<0.05),but the skill test score of the two groups was not statistically significant(P>0.05).Among masters,the written test scores and skill test scores of the 3D+CBL group were better than those of the CBL group,and the differences were statistically significant(both P<0.05).The teaching and satisfaction scores of the undergraduate and master's 3D+CBL groups were higher than those of the CBL group,and the differences were statistically significant(both P<0.05).Conclusion The medical 3D printing digital cloud platform can significantly improve the effect of spine surgery CBL teaching.
