  • Crossing the Quality Chasm (IOM, 2001)
  • Studies in medicine and nursing indicated that interventions based on evidence have better outcomes.
evidence based practice1

Definition

    • Evidence Based Practice of nursing is the process by which nurses make clinical decisions using the best available research evidence, their clinical expertise and patient preferences.
      • Nurse, Clinical Expertise, Patient, Evidence
  • Reality
    • We use evidence everyday without thinking about it
    • Sources of evidence can be too few or too many
    • It’s easier to base practice on myths and the way we have always done things than attempt to understand the evidence and change practice
Evidence-Based Practice
ebp combines the art and science of nursing

Essentials of practice

    • Art
      • Our ability to connect to those around us
      • We just ‘know’ what to do to meet a patient’s emotional needs: when to hold a patient’s hand, stroke their brow, crack a joke or even just sit and listen
      • Calls you to the profession
    • Science
      • Body of knowledge
      • Uses scientific methods
      • Generate and test theory, discover meaning, and grow knowledge
      • A scholarly adventure
EBP combines the art and science of nursing
the process of ebp

Ask the burning clinical question (PICO).

Collect the best evidence.

Critically appraise the evidence.

Integrate the evidence, clinical expertise, and patient factors/preferences to implement a decision.

Evaluate the outcome.

The Process of EBP
the link between ebp and research
The Link Between EBP and Research
  • Research
    • Conducted a systematic & scientific manner
    • Follows a series of steps with a rigorous standard protocol
    • Purpose is to generate new knowledge
    • Evidence-based Practice
      • The process by which nurses make clinical decisions using the best available research evidence, their clinical expertise and patient preferences
  • Where are the similarities and differences?
    • Both use a process/specific approach
    • Both are trying to gain something – knowledge, a new way of doing something
    • Research more ‘rigorous’ with more steps
    • Research tries to gain new knowledge whereas EBP might try to confirm knowledge

    • Provides an organized approach
    • Prevents incomplete implementation
    • Maximizes nursing time and resources (Gawlinski & Rutledge, 2008)
john hopkins ebp model guidelines

Depicts 3 essential cornerstones that form the foundation for professional nursing

Nursing practice is the means by which a patient receives nursing care; education reflects the acquisition of the nursing knowledge and skills necessary to become a proficient clinician and to maintain competency; and research provides new knowledge to the profession and enables the development of practices based on scientific evidence.

knowledge transformation

-the conversion of research findings from primary research results, through a series of stages and forms, to impact on health outcomes by way of EB care

    • Knowledge transformation is necessary before research results are useable in clinical decision making.
    • Knowledge derives from a variety of sources. In healthcare, sources of knowledge include research evidence, experience, authority, trial and error, and theoretical principles.
    • The most stable and generalizable knowledge is discovered through systematic processes that control bias, namely, the research process.
    • Evidence can be classified into a hierarchy of strength of evidence. Relative strength of evidence is largely dependent on the rigor of the scientific design that produced the evidence. The value of rigor is that it strengthens cause-and-effect relationships.
Knowledge Transformation
knowledge transformation1

Knowledge exists in a variety of forms. As research evidence is converted through systematic steps, knowledge from other sources (expertise, patient preference) is added, creating yet another form of knowledge.

  • The form (\'package\') in which knowledge exists can be referenced to its use; in the case of EBP, the ultimate use is application in healthcare.
  • The form of knowledge determines its usability in clinical decision making. For example, research results from a primary investigation are less useful to decision making than an evidence-based clinical practice guideline.
  • Knowledge is transformed through the following processes:
    • summarization into a single statement about the state of the science
    • translation of the state of the science into clinical recommendations, with addition of clinical expertise, application of theoretical principles, and client preferences
    • integration of recommendations through organizational and individual actions
    • evaluation of impact of actions on targeted outcomes

ebp case story from asu college of nursing health innovation

A dog bit my mother-in-law three weeks ago. She has known the dog for many years, but the immunization status of the dog was unconfirmed. Her wound was small, so she did not seek treatment at that time. The biggest fear after a dog bite is contracting rabies. Rabies is a zoonotic disease (one transmitted to humans from animals) caused by a virus.

Last week she went to her primary care provider (PCP) for treatment, two weeks after the initial bite. Her PCP recommended rabies post-exposure immunization. My husband, a resident physician, and I were shocked as neither of us has ever recommended the rabies immunization for post-exposure treatment in a case like hers. We both quickly consulted our databases of choice for a quick look at what we thought were the recommendations for rabies treatment. I consulted www.emedicine.com and found “Human rabies immune globulin and vaccine are recommended for bites and exposures regardless of the period between exposure and treatment unless the individual is previously vaccinated and rabies antibodies can be detected.” (2007, 11).

EBP Case Story from ASU College of Nursing & Health Innovation
case continues

Of note, the average delay in the United States between exposure and treatment is 5 days, which does not appear to compromise successful prophylaxis. My husband consulted the Up to Date database and found “for persons who have never been vaccinated against rabies, post-exposure antirabies vaccination should always include administration of both passive antibody (HRIG) and vaccine (human diploid cell vaccine [HDCV] or purified chick embryo cell vaccine [PCECV])”. Finally we looked at the Centers for Disease Control (CDC) website and found their recommendation to be “for persons who have never been vaccinated against rabies previously, post-exposure anti-rabies vaccination should always include administration of both passive antibody and vaccine”. Post-exposure prophylaxis is a series of multiple injections around the already painful wound and follow-up is generally poor for patients (Moran, G.J. Talan, D.A. Mower, W. Newdow, M., Ong, S., Nakase, J., et al., 2000).

Case continues…
case continues1

We were frustrated and confused. It seemed that all three databases recommended that the post-exposure vaccine be given. Yet in all of the nine facilities that we have worked in across three different states, this has never been standard of care.

Since I have been learning the process of evidence-based practice (EBP) and how to search the literature for the best evidence, I thought that I would apply it to this situation. A PICO question was developed to drive the search of the literature. In (p) patients with animal bites does the (i) administration of post-exposure prophylaxis (PEP) compared to (c) observation or testing of the animal only (o) provide the most appropriate treatment?

Case continues…
case the end

I performed a quick search of the CINAHL, PubMed, and Google Scholar databases. After rapidly critically appraising the articles I found and synthesizing my findings, I know that I now have a validated response to my mother in law when I say that the post-exposure treatment of rabies is not warranted in her case. I can show her the evidence. There is even an easy algorithm to follow called the "Algorithm for Determining Appropriateness of Animal Exposure Treatments" (Moran, G.J. Talan, D.A. Mower, W. Newdow, M., Ong, S., Nakase, J., et al., 2000).

My “EBP Story” shows how I have taken what I have learned in the last five months and not only applied it to my practice, but also my personal life.

This week my mother-in-law’s dog drank antifreeze. Perhaps next week I will do a mini-synthesis of evidence for a recommendation on the treatment for that issue.
