Evidence Based Practice Models and Using the Guide

In 2015, OHSU Healthcare adopted the Johns Hopkins Evidence-Based Practice Model (JHEBP) to frame clinical inquiry initiatives.

EBP is a problem-solving approach to clinical decision-making within a health care organization. It integrates the best available scientific evidence with the best available experiential (patient and practitioner) evidence. EBP considers internal and external influences on practice and encourages critical thinking in the judicious application of such evidence to the care of individual patients, a patient population, or a system (Newhouse, Dearholt, Poe, Pugh, & White, 2007).

The JH Evidence-based Practice Model occurs in three phases: Practice Question, Evidence, and Translation.

Practice Question: The first phase includes forming a team and developing an EBP answerable question.  

Evidence: The second phase includes searching for, evaluating, and synthesizing the best available evidence.

Translation: In the third phase, team members identify setting-specific recommendations, create and implement an action plan, evaluate outcomes, and disseminate findings.


With the JHEBP in mind, use the sections in this guide to learn:

  • More about EBP and how it is implemented
  • How to ask a searchable EBP question
  • What types of evidence to look for
  • Where to search for the best evidence
  • How to appraise the evidence you find
  • How to get help and additional support
