Introduction

• Evidence-Based Medicine: What it is and what it isn't
• Evidence-based Medicine: A New Approach to Teaching the Practice of Medicine

Evidence-Based Practice is a five-step process:

1. Construct a relevant, answerable question from a clinical case.
2. Plan and carry out a search of the literature for the best external evidence.
3. Critically appraise the literature for validity and applicability.
4. Apply the evidence to your clinical practice.
5. Evaluate your performance.

Constructing a relevant, answerable question

• Flemming K. EBN notebook. Asking answerable questions. Evidence-Based Nursing 1998;1:36-37.
• Formulating Answerable Clinical Questions (Centre for Evidence-Based Medicine, Mount Sinai Hospital) Including: Educational prescription
• The Well-Built Clinical Question (Duke University Medical Center Library and Health Sciences Library, UNC-Chapel Hill
• Formulating Patient Centered Questions (University Library, University of Illinois at Chicago)
• Asking Focused Questions (Centre for Evidence-Based Medicine, Oxford)

Hierarchy of pre-processed evidence

[ [Adapted from DiCenso, Bayley and Haynes (2009). ACP Journal Club. Editorial: Accessing pre-appraised evidence: Fine-tuning the 5S model into a 6S model. Annals of Internal Medicine, 151(6):JC3-2, JC3-3.]

Systems

“An evidence-based clinical information system integrates and concisely summarizes all relevant and important research evidence about a clinical problem, is updated as new research evidence becomes available, and automatically links (through an electronic medical record) a specific patient’s circumstances to the relevant information."

Summaries

"These include clinical pathways or textbook summaries that
integrate evidence-based information about specific clinical
problems and provide regular updating."

Syntheses: Systematic Reviews

"A synthesis or systematic review is a comprehensive summary of all the research evidence related to a focused clinical question."

Synopses

“...a synopsis that summarizes the findings of a high-quality systematic review can often provide sufficient information to support clinical action... the synopsis of a single study provides a brief, but often sufficiently detailed, summary of a high-quality study that can inform clinical practice."
