PBL结合询证医学模式在普通外科临床教学中的应用

目的:基于问题的学习(PBL)结合询证医学(EMB)模式在普通外科临床教学中的应用。方法:选择2015年9月到2016年1月在我院学习的普通外科专业学生74例纳入本次研究,根据简单数字随机表法将其划分为观察组(PBL结合EBM教学模式)以及对照组(传统教学模式)各37例,对比两组考试成绩,课程相关指标,以及评优情况。结果:观察组的基础知识得分、主观题考试得分、个案分析得分以及总分均分别明显高于对照组,差异均有统计学意义(均P0.05)。观察组的课前准备时间、课堂发言次数及授课满意度均明显大于对照组,差异均有统计学意义(均P0.05)。观察组药物选择合理、患者状态评估准确以及符合临床实际上的评优率均明显高于对照组,差异有统计学意义(P0.05)。结论:PBL结合EBM模式应用在普通外科的临床教学过程中,效果明显,能较好地激发学生学习兴趣并提高其学习成绩,还可提升学生的评优率,值得给予推广。

Clinical Application of PBL Combined with Evidence-based Medicine in Clinical Teaching of General Surgery

ABSTRACT Objective: To study clinical application of problem based learning(PBL)combined with evidence-based medicine model(EBM)in general surgery clinical teaching. Methods: 74 cases of general surgery students were enrolled in this study in our hospital from September 2015 to January 2016, they were divided into observation group(PBL combined with EBM teaching mode)and control group(traditional teaching mode), with 37 students in each groups according to the random number table method, test scores, curriculum related indicators and superior evaluation situation were compared in two groups. Results: The basic knowledge score, subjective test score, the case analysis score and the total score in the observation group were significantly higher than control group, the differences were statisti- cally significant(P<0.05). Class preparation time,class speech times and teaching satisfaction in observation group were significantly greater than the control group, the differences were statistically significant(both P<0.05). The superior evaluation rates rational drug se- lection, patient status assessment accurate and conforming to clinical practice in observation group were significantly higher than control group, the differences were statistically significant(P<0.05). Conclusion: Using PBL combined with EBM model in general surgery clini- cal teaching process, the effect is obvious, which can stimulate the interest of students in learning and improve their learning perfor- mance, as well as enhance the superior evaluation rate, it is worthy of promotion.
