Evidence-based literature comes from many sources. The discipline of nursing has an
abundance of research data and resources to guide clinical decisions. Therefore, it is of
pivotal importance to understand the basic tenets of critical appraisal of such evidence for its
use in interprofessional healthcare practices.
In this task, you will identify a healthcare problem, develop an evidence-based practice (EBP)
question, and review selected research-based and non-research-based evidence to find
answers to that question.
Note that while you will be analyzing only one research-based and one non-research-based
article in this task, an actual evidence-based practice change would require the support of
many high-quality research studies.
B. Discuss the impact of a clinical practice problem on the patient or patients and the organization
it affects.
1. Identify each of the following PICO components of the clinical practice problem:
• P: patient, population, or problem
• I: intervention
• C: comparison
• O: outcome
2. Develop an evidence-based practice (EBP) question based on the clinical practice problem
discussed in part B and the PICO components identified in part B1.
Note: Refer to the “Appendix B: Question Development Tool” web link for information on the creation of an
EBP question.
C. Select a research-based article that answers your EBP question from part B2 to conduct an
evidence appraisal.
Note: The article you selectshould not be more than five years old.
1. Discuss the background or introduction (i.e., the purpose) of the research-based article.
2. Describe the research methodology used in the research-based article.
3. Identify the level of evidence for the research-based article using the Johns Hopkins Nursing
Evidence-Based Practice (JHNEBP) model.
Note: Refer to the “Appendix E: Research Evidence Appraisal Tool” web link for information on how to level
a research-based article.
4. Summarize how the researcher analyzed the data in the research-based article.
5. Summarize the ethical considerations of the research-based article. If none are present,
explain why.
6. Identify the quality rating of the research-based article according to the JHNEBP model.
Note: Refer to the “Appendix E: Research Evidence Appraisal Tool” web link for information on how to
establish the quality rating.
7. Analyze the results or conclusions of the research-based art
