Abstract: Objective To investigate the training effect of evidence-based medicine courses on the critical thinking ability of medical postgraduates. Methods Questionnaire survey was used. From September to November 2020, medical postgraduates of Wuhan University who participated in the courses of Evidence-based Medicine and Evidence-based Clinical Practice (evidence-based medicine courses) in 2020 were taken as the survey objects. The Chinese version of critical thinking disposition inventory was used to measure the critical thinking abilities of students before and after the courses. Wilcoxon signed rank tests, Wilcoxon rank sum tests, Kruskal-Wallis tests were used for data analysis. Results A total of 331 valid questionnaires were collected. The total score of critical thinking of medical postgraduates after the evidence-based medicine courses 297.0(45.0) was higher than that before the courses291.0(40.0), P=0.001. The score of truth seeking , systematic ability and self-confidence of critical thinking after the courses were significantly higher than those before the courses [40.0(9.0) vs. 38.0(7.0), 41.0(9.0) vs. 40.0(8.0), 39.0(6.0) vs. 39.0(6.0)], all P<0.05. The change in critical thinking ability scores before and after evidence-based medicine courses of students who participated in research projects before the courses was higher than that of those who did not participate in research projects(6.0 points vs. 1.5 points), P=0.032. Conclusions Evidence-based medicine courses can improve the critical thinking abilities of medical postgraduates, and participating in research projects before the courses will further enhance the training effect of evidence-based medicine courses on critical thinking abilities.
