医学研究生应用循证医学现状调查

目的了解目前医学研究生应用循证医学的现状和在循证临床实践中的困难与障碍,为进一步开展循证临床实践和循证医学教学提供参考。方法对2005年春、秋季四川大学选修《循证医学》的365名1、2年级医学研究生进行问卷调查,并对结果进行比较分析。结果365份调查问卷全部收回。调查结果显示:入学前约半数学生通常每月阅读专业文献1~5篇;56.0%的学生能在自己的临床决策中应用文献结果;57.3%的学生使用电子文献数据库;61.4%的学生不能较容易的获得相关的临床指南;68.5%学生没有在临床决策中使用相关指南。循证临床实践的主要困难依次为:文献检索策略难掌握;对循证医学了解不够;无法获得免费全文资源;受经验影响,执行上级医师的决策;证据质量不确定;花费时间较多。结论循证临床实践和循证医学教学已开始从宣传普及向技能获取阶段转化。

A Survey of the Application of Evidence-based Medicine in Medical Postgraduates

Objective To investigate the use of evidence-based medicine (EBM) and barriers to applying EBM in clinical practice in medical postgraduates. Methods Three hundred and sixty-five first and second-year medical postgraduates selecting the EBM courses were included. All the students were surveyed by questionnaires. Result The response rate to the survey was 100%. About half of the students read 1~5 professional articles per month before postgraduate study. Fifty-six percent of the students used professional literature and research findings when making clinical decisions. Fifty-seven point three percent used electronic databases to search for practice-relevant literature before postgraduate study. Sixty- one point four percent found it difficult to obtain relevant clinical guidelines and 68.5% never applied relevant clinical guidelines in clinical decision-making. The barriers to using EBM in clinical practice included difficulties in searching and accessing full text of potentially relevant articles, lack of EBM knowledge, influences from clinical experience and authorities, uncertainties about the quality of evidence and time-consuming. Conclusion EBM clinical practice and EBM medical education has transformed from dissemination and popularization stage to skill acquisition stage.
