摘要：Objectives: The purpose of this study was to assess the efficacy of a concise, evidence based medicine curriculum in improving the knowledge of pediatric residents at two institutions. Methods: Sixty first and second year pediatric residents at MassGeneral Hospital for Children and MedStar Georgetown University Hospital participated in a crossover study. The evidence based medicine curriculum, consisting of 4 ninety minute sessions grounded in adult learning theory principles, was developed using the methodology described in the book ‘Studying a Study’. A validated 20 question evidence based medicine multiple choice test was administered on three separate occasions to measure baseline knowledge, efficacy of the curriculum in improving knowledge, and long term retention of that knowledge. Results: Post curriculum, the fall group’s scores improved 23% from baseline (M=10.3, SD=2.4) to (M=12.7, SD=3.0) students (t(26)=-3.29, p=0.0018) while the spring group improved by 41% (M=10.0, SD=2.8) to (M=14.1, SD=2.2) students (t(32)=-6.46, p<0.0001). When re-tested 4-6 months later, the fall group’s scores did not significantly decline from their immediate post curriculum scores (M=12.7, SD=3.0) to (M=11.7, SD=3.0) students (t(32) =1.33, p=0.190). There was an association between number of sessions attended and increase in post curriculum score (χ2(3, N=60) =11.75, p=0.0083). Conclusions: Findings demonstrate our curriculum was effective in teaching evidence based medicine to pediatric residents, and fostered long term retention of knowledge. Based on these results, we believe this curriculum could be implemented at any institution.
