LIBRARY GUIDE TO NRS 3012 - Research for Evidence-based Practice

Steps of a Literature Review
  • 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
PICO example
Asking is fundamental to the evidence-based decision-making process.
A "well-built" question should include four parts, referred to as PICO that identify the patient problem or population (P), intervention (I), comparison (C) and outcome(s) (O).

Example: How do alternative breast cancer treatments improve the quality of life for young adult females?
P= young adult females with breast cancer 
I =  alternative therapies 
C= patients who don't use alternative therapies 
O= quality of life improvement

Evidence-Based Practice Steps (EBP)
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
