目的开发和验证一种用于测量循证医学知识和技能的工具，并调查循证医学短期课程是否会导致知识和技能的有意义的增加。设计开发和验证评估工具以及研究前后。设置德国各种循证医学研究生短期课程。参与者该工具与循证医学专家进行了验证。医学、研究生医生和医学生。课程的效果由来自医学和外科背景的研究生医生评估。通过导师提供的为期3天的循证医学干预强化课程为小组提供了便利。主要成果指标知识和技能的提高。结果问卷可靠地区分了具有不同循证医学专业知识的群体。专家的平均得分是学生的三倍。没有上过课的研究生的表现比学生好，但比专家差得多。循证医学知识和技能在课程结束后提高了57%（课程前平均得分6.3（SD 2.9）vs9.9（SD 2.8），P < 0.001）。没有发现专家或学生之间的差异，在没有intervention.Conclusions可靠的工具评估知识和技能的循证医学。为期3天的强化循证医学课程导致知识和技能的显着增加。
Objective To develop and validate an instrument for measuring knowledge and skills in evidence based medicine and to investigate whether short courses in evidence based medicine lead to a meaningful increase in knowledge and skills.Design Development and validation of an assessment instrument and before and after study.Setting Various postgraduate short courses in evidence based medicine in Germany.Participants The instrument was validated with experts in evidence based medicine, postgraduate doctors, and medical students. The effect of courses was assessed by postgraduate doctors from medical and surgical backgrounds.Intervention Intensive 3 day courses in evidence based medicine delivered through tutor facilitated small groups.Main outcome measure Increase in knowledge and skills.Results The questionnaire distinguished reliably between groups with different expertise in evidence based medicine. Experts attained a threefold higher average score than students. Postgraduates who had not attended a course performed better than students but significantly worse than experts. Knowledge and skills in evidence based medicine increased after the course by 57% (mean score before course 6.3 (SD 2.9) v 9.9 (SD 2.8), P < 0.001). No difference was found among experts or students in absence of an intervention.Conclusions The instrument reliably assessed knowledge and skills in evidence based medicine. An intensive 3 day course in evidence based medicine led to a significant increase in knowledge and skills.
