EBP: What’s the point? & What is it anyway?*

The next few blogs will focus on how to improve your nursing practice by finding & using the best evidence.

  • 1st– What is the point or goal of evidence-based practice (EBP)? Best patient care.
  • 2nd– What is the definition of Evidence based Practice (EBP)?

Evidence-based Practice (EBP) =

Best evidence(research &/or nonresearch) +

Clinical Expertise +

Patient/family preferences & values

(See http://guides.mclibrary.duke.edu/c.php?g=158201&p=1036021 for more.)

  • 3rd– What should I do step-by-step to use the best evidence in order to give BEST patient care? At Dignity NHMC we use the Iowa model as a step-by-step guide (Titler et al, 2001). (Other readers should check to see if their hospital has adopted a model that they should follow.)   NHMC employees can find a copy of the Iowa model reprinted with permission and other information at S:\Everyone\everyone\EVIDENCE BASED PRACTICE-RN Scientist Role.  Additionally NHMC employees can contact the nursing EBP/research facilitator at martha.highfield@dignityhealth.org or extension 3339 for questions or one-to-one help.
  • What is the general process of EBP?Most models include the following elements:
  1. Identify clearly the clinical issue that needs solving.Maybe this is a problem that you’ve encountered in your practice, or maybe it is something you heard about from a colleague or journal. For example, what is the best way to manage injection pain in children?
  2. Find the best evidence. Research is typically regarded as best evidence.  When no research has been done on the topic we can still use expert opinions, case studies, and scientific principles.
  3. Critique the strength of the evidence. This is figuring out how much confidence you have that the research studies are coming to the right conclusions.  If you’re not sure, an NP or CNS could help or point you to another mentor.
  4. Combine (synthesize) all evidence.When research study outcomes contradict each other, then we have to look at which studies are most carefully done.  Again an APN can help.
  5. Write clinical recommendations for your settingbased on best evidence+clinical expertise+patient/family values & preferences.
  6. Try out (or pilot) the clinical recommendationsin your setting using clinical judgment and patient/family preferences and values.
  7. Evaluate the outcomes.
  8. PRN “tweak” your recommendations to improve outcomes& roll out the project to other units if appropriate.
  9. Reinforce the “new & improved” evidence-based practiceso that it is sustained.
  10. Monitor outcomes.

CRITICAL THINKING:  What is one patient-care issue that you think can be improved on your unit?  For example: Reducing post-op ileus? Cutting down on nighttime noise on the unit? Dealing with nurses’ potential alarm fatigue?  Other?   Write the problem out.  Writing it out makes you think it through more clearly so don’t just think it—write it.  Then, STAY TUNED next blog for more on clarifying the problem.
