Journal Club Format : Journal Club Format With the help of your preceptor, perform a literature search and choose a key article that addresses your question (Medical Librarians can also help with this step!) Use the User’s Guide to the Medical Literature and/ or Sackett’s EBM book to assess the validity, importance, and applicability of the results depending on the type of study you are appraising (this is the really important part!) On-line User’s Guide, Critical Appraisal Worksheets, and other toolkits will be available through links on the website Format for the Presentation : Format for the Presentation Present the clinical scenario and your clinical question Review the search strategy used Review the critical appraisal Address how the results may apply to your patient and/or to future patients What is EBM? : What is EBM? “Evidence based medicine is the integration of individual clinical expertise with the best available external evidence from systematic research” Sackett D.
