摘要目的 研究EBM-PBL在呼吸科临床教学中的应用效果.方法 将47名八年制临床医学专业学生分为两组,实验组采用EBM-PBL,共27名学生;对照组采用单纯PBL,共20名学生,应用客观指标和主观指标评价教学效果,用SPSS 13.0软件进行数据分析,组间比较用Fisher确切概率法.结果 实验组学生提供高级别证据(A级)的比例为51.3％,明显高于对照组的30.2％(P<0.05);实验组有约90％的学生认为EBM-PBL有助于提高信息获取与利用能力、分析解决问题能力和综合多学科文献资料能力,教学满意度明显高于对照组(P<0.05).结论 EBM-PBL在提高学生综合能力的同时,有助于培养学生的证据意识,从而有利于提高学生的临床决策水平,优于单纯PBL.

abstractsObjective To investigate the application of evidence-based medicine combined problem-based learning in clinical teaching of respiratory medicine. Methods 47 students were divided into two groups. EBM-PBL was applied in the experimental group including 27 students and PBL was applied in the control group including 20 students. Teaching effect was evaluated by objective and subjective indicators. Data were analyzed using SPSS 13.0 software and Fisher's exact probability test was also applied. Results The proportion of high level evidences (grade A) that provided by the students in experimental group (51.3％) was significantly higher than that in the control group (30.2％) (P<0.05). About 90％ students in the experi-mental group believed that EBM-PBL could improve their abilities of information acquisition and utiliza-tion, problem analysis and solving as well as multiple discipline literature synthesizing, which was signifi-cantly higher than that in the control group (P<0.05). Conclusion EBM-PBL could cultivate the students' awareness of evidence and the level of clinical decision-making so as to enhance their comprehensive abil-ities, which was superior to mere problem-based learning.
