LIBRARY GUIDE TO Crittenton Nurses - EBP Research

PICO Method & EBP
Asking a good question is fundamental to the evidence-based decision-making process. A "well-built" question should include four parts, PICO stands for (P) patient, problem or population, (I) intervention, (C) comparison and (O) outcome(s).

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