Evidence-Based Practice

As stated by Melnyk et al.:

EBP is a problem-solving approach to the delivery of health care that integrates the best evidence from well-designed studies and patient care data, and combines it with patient preferences and values and nurse expertise (pg. 51).

Melnyk, B. M., Fineout-Overholt, E., Stillwell, S. B., & Williamson, K. M. (2009). Igniting a spirit of inquiry: An essential foundation for evidence-based practice; how nurses can build the knowlede and skills they need to implement EBP. The American Journal of Nursing, 109(11), 49. www.jstor.org/stable/25734232

 

Levels of Evidence

In evidence-based practice, nurses use levels of evidence to evaluate and assess a study's strengths and weakness. This can lead to evidence-based changes to clinical practice. 

 

Level 1     Systematic reviews or meta-analyses
Level 2     Randomized controlled trials
Level 3     a. Cohort studies (with control group)
                  b. Case-controlled 
                  c. Observational studies (without control group)
Level 4     Expert opinion, physiology bench research, or consensus
