ObjectivesThe 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.
MethodsSixty 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).
ConclusionsFindings
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.
