A guide for finding nursing resources and information

Research Resources

This 3:17 min. video produced by OVIDWoltersKluwer introduces students to evidence-based practice within the context of nursing.

What is Evidence-based Practice?

PICO = Patient, Intervention, Comparison, Outcome

Echevarria, I., & Walker, S. (2014). To make your case, start with a PICOT question. Nursing, 44(2), 18-19.

P -- Patient/Problem/Population

I -- Intervention

C -- Comparison

O -- Outcome

T -- Treatment

Example: I am looking to explore the effectiveness of restraints in reducing the occurrence of falls in patients aged 65+.

NOTE: The O and T is what you will find in the literature (clinical trials, systematic reviews, meta analysis).

This tutorial is designed to provide the student with a greater understanding of the various types of research used in evidence-based practice (EBP). The tutorial begins at the base and progresses to the point.  The student may move to the various levels as needed.  There are questions to test yourself about each study type, some helpful formulas related to the study types, a video demonstrating how to find each type of study, and a glossary of relevant terms.

The student may also click on the pyramid below to access the tutorial.

  • Mental Measurements Yearbook (commercially available instruments)
