Evidence Based Nursing

Why is EBP Important?

Evidence based practice (EBP) is the conscientious use of current best evidence in making decisions about patient care (Sackett, Straus, Richardson, Rosenberg, & Haynes, 2000).

You might be asking, "Why do I need to know how to develop EBP research skills?"
Here are a few reasons: 

  • Knowing how to find evidence (such as RCTs or Meta-Analyses) are likely to result in the desired patient outcome
  • Provides opportunities for nursing care to be more individualized
  • Allows nurses to stay up to date with latest developments

Youngblut, J. M., & Brooten, D. (2001). Evidence-based nursing practice: Why is it important? AACN Clinical Issues, 12(4), 468-476.

Why is PICO(T) Important?

Knowing how to form a PICO(T) question helps you get evidence to support best practices. In academia, you use the question to:

  • Focus the scope of your issue to get relevant results
  • Develop keywords that will help you search for evidence
  • Get more manageable results with a focused search strategy
  • Save time!

Creating a Question

PICO describes the process of defining a problem and creating a clinical question, e.g., a good clinical question will include all :

P Patient population of interest   

I Intervention/issue of interest  

C Comparison of interest 

O Outcome of interest                

Sometimes, a fifth element, Time, is added to the process          

Example: In acute care patients, how do repositioning initiatives, compared to no initiatives, affect hospital acquired pressure ulcers?

P Patient population of interest and/or problem  =    Acute Care Patients
I Intervention/issue of interest  =                            Repositioning Initiatives
C Comparison of interest =                                    No treatment
O Outcome of interest =                                        Decreased risk of pressure ulcer

Identify the topics and terms from your question to search the literature 

Search Tip: Begin with a broader search by using only a couple of elements, such as P (population) and I (intervention). Based on your results, you can add in keywords that fit the other PICO(T) elements.
