Evidence-Based Practice (EBP) Steps

  1. Problem Identification: Converting information needs into an answerable question
  2. Finding the Evidence: Finding, with maximum efficiency, the best evidence with which to answer the question
  3. Critique: Determining the merit, feasibility and utility of evidence
  4. Summarize the Evidence: Combining findings from all evidence to make a practice recommendation
  5. Application to Practice: Incorporating the recommendation into a clinical setting or organization
  6. Evaluation – Determining the effective of the practice over time

Steps in Reviewing the Literature

  • Problem formulation - which topic or field is being examined and what are the component issues?
  • Literature search - finding materials relevant to the subject explored
  • Data evaluation - determining which literature makes a significant contribution to the understanding of the topic
  • Analysis and interpretations - discussing the findings and conclusions of pertinent literature
