Describe the levels of evidence in each of the four peer-reviewed articles you selected, including an explanation of the strengths of using systematic reviews for clinical research.

Ebp | NURS 6052 – Essentials of Evidence-Based Practice | Walden University

Four peer-reviewed papers I chose had different levels of evidence ranging from systematic reviews to primary research. First, the first paper I selected was a qualitative investigation based upon interviews with nurses that provided insights into their experience regarding palliative treatment. This falls under primary research because it’s an original study which gathers data directly from sources. Comparatively, the second study was an observational retrospective research conducted through medical records. This can be classified secondary evidence because it uses existing data to analyze.

This type of literature allows practitioners to be more informed when making decisions about patients. The fourth article was a systematic study combining several studies on spiritual needs. The papers highlight how all kinds of evidence is necessary to achieve a complete understanding, and also the benefits that systematic reviews can bring in terms of best practices.
