Introduction: Evidence-based medicine (EBM) integrates published clinical evidence with patient values and clinical expertise, the output of which is informed medical decision making. Key skills for evidence-based practice include acquisition and appraisal of clinical information. Faculty clinicians often lack expertise in these skills and are therefore unable to exemplify this process for students and residents.
Methods: We conducted a yearlong case-based EBM workshop for 28 clinician educators, with precourse and postcourse evaluations of EBM resource use and literature appraisal skills.
Results: Of the original 28 participants, 26 completed the course. Self-assessed EBM resource use improved significantly. Self-reported EBM knowledge correlated with measured skill (r = 0.45), and both improved with the intervention (both p < .0005). Higher EBM skills scores correlated with time logged on the course's EBM Web sites (r = 0.56; p < .05), workshop attendance rates (r = 0.55; p = .003), and fewer years since medical school graduation (r = -0.56; p < .005).
Discussion: An interactive, longitudinal, EBM course derived from a needs assessment can improve 2 skills important for evidence-based practice: online literature retrieval and critical appraisal skills.
Lessons for Practice
- Practicing clinicians and clinician educators often lack information-searching and critical appraisal skills to practice evidence based medicine (EBM).
- A greater number of years since medical school graduation may predict lower literature appraisal skills.
- Time spent using online EBM resources can increase understanding of EBM principles.
- Education to increase EBM skills should promote the use of online EBM resources.
- Case-based, longitudinal EBM workshops can promote increased EBM resource use and improved literature appraisal skills.
