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

The four peer-reviewed articles I selected had varying levels of evidence, ranging from primary research to systematic reviews. The first paper was a qualitative study based on interviews with nurses which provided insight into their experiences regarding palliative care; this falls under the category of primary research as it is an original investigation that collects data from firsthand sources. In comparison, the second paper was a retrospective observational study conducted by examining medical records which can be classified as secondary evidence since it relies on existing data for analysis.

The third article used quantitative methods to explore patient perceptions towards end-of-life care thus providing another example of primary research whereas the fourth was a systematic review combining multiple studies related to spiritual needs at end of life; this type of literature provides information about how different interventions have impacted outcomes across various contexts thus allowing practitioners to make more informed decisions when treating patients. Overall, these papers demonstrate how all types of evidence are necessary in order to gain comprehensive understanding while also highlighting the value that systematic reviews bring when considering best practices in healthcare today.
