| 目的 系统评价以问题为基础的学习（problem-based learning，PBL）结合循证医学（evidence-based medicine，EBM）教学在住院医师规范化培训中应用的教学效果。方法 计算机检索中国知网、万方数据、维普、中国生物医学文献数据库、EMbase、PubMed和Web of SCI数据库，搜集有关EBM结合PBL教学在住院医师规范化培训中应用的随机对照试验（randomized controlled trial，RCT）。检索时限均从建库至2018年7月1日。由两名研究者独立进行筛选文献、提取资料并评价纳入研究的偏倚风险后，采用RevMan 5.3软件进行Meta分析。结果 最终共纳入4个研究。因研究结局指标不一及文献质量较低无法进行定量合成，故采用描述性方式进行分析总结。结果显示，与基于课堂的灌输式教学（lecture-based learning，LBL）教学相比，EBM结合PBL教学组在住院医师规范化培训中大部分指标均取得更优的成绩，尤其是病例分析得分、考试总分、提高临床思维能力、交流表达能力、组织协作能力等方面具有更多优势。结论 当前证据提示EBM结合PBL教学在住院医师规范化培训中的应用具有一定的教学效果，比起传统LBL教学来讲更能提升学生能力。但受纳入研究数量和质量的限制，上述结论尚待更多大样本高质量研究予以验证。 |

| Objective To systematically review the teaching effect of problem-based learning (PBL) combined with evidence-based medicine (EBM) teaching mode on the standardized residency training. Methods CNKI, Wanfang database, VIP database, SinoMed, Embase, PubMed and Web of SCI databases were searched, and the randomized controlled trial (RCT) studies of the application of EBM combined with PBL teaching in standardized residency training were collected. The retrieval time was from the establishment to 1st July, 2018. Two investigators independently extracted data and assessed the quality of the studies. After assessing the risk of bias of included studies, Meta-analysis was performed on RevMan 5.3. Results In total, 4 studies were included in the review. Narrative assessment was adopted, because outcome indicators of these study were varied and the quality of the literatures could not meet the requirement of Meta-analysis. Our study suggested that the residents who were in PBL combined with EBM teaching mode group got higher scores in the standardized residency training, compared with those in the lecture-based learning (LBL) teaching mode group, especially in case analysis score, total score of examination, improvement of clinical thinking ability, communication and expression ability, organization and cooperation ability, etc. Conclusion The current evidence suggests that the application of EBM combined with PBL teaching mode has a positive effect on the standardized residency training. Compared with the traditional LBL teaching, EBM can improve students' ability. However, limited by the quantity and quality of included studies, the above conclusions still need to be verified by more studies with larger samples and higher quality. |
