This 18:55 min. video produced by OVIDWoltersKluwer introduces students to evidence-based practice within the context of nursing.

What is Evidence-based Practice?

Johns Hopkins Evidence-based Practice Model

Evidence-based Nursing -- British Journal of Medicine (BJM)

The archive provides full text access to issues from 1995 (volume 1, issue #1 to 2005 (volume 8, issue #4). Use the Publication Finder to discover what access to full text content might be available through the NNU Riley Library's databases. 

If the article you seek is not available full text through a library database, please use the interlibrary loan service to request the article from another library. It typically takes 3 to 5 business days to get the article, and it will be delivered to you electronically via your NNU email. 

What is a PICO statement?

A PICO is developed in clinical practice to guide the care and research for care of the patient. An example is included below:

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).

Evidence-based Practice Tutorial [self-guided]

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.

Locating instruments for research can sometimes be a daunting task. Here are few pointers to locate interview questions, questionnaires, surveys, pre-/posttests, etc.:

  • Dissertations (can be found by searching EBSCO and the ProQuest Dissertations & Theses databases). If you search EBSCO, you will need to copy and paste the dissertation title into the ProQuest database to obtain the full text of the dissertation.
  • Research articles (sometimes you may need to contact the researcher to obtain a hard copy of the instrument)
  • Mental Measurements Yearbook (commercially available instruments)

Northwest Nazarene University requires that all research requiring the use of human subjects to be approved by the Human Research Review Committee. The policies and documents are listed below. Please contact your advisor or research coordinator for additional information.
