An important step in the EBP process is reviewing the current body of literature to better understand the subject or topic in which you are interested. By conducting a review of the literature, you are building foundational knowledge about the topic; later, you can use this background to build new insights. Developing a strong grasp of a topic can only be garnered by taking the time to thoroughly search for relevant information and resources.

For this Discussion, you will practice searching the literature to find evidence on a specific topic.

To prepare:

  • Choose a simple search term(s) relating to a topic of your PICOT question.
  • Review the information on the evidence hierarchy discussed in Chapter 2 of the course text, in the article, “Facilitating Access to Pre-Processed Research Evidence in Public Health,” and in the multimedia presentation “Hierarchy of Evidence Pyramid,” found in this week’s Learning Resources.
  • Review the information on the Walden Library’s website, “Levels of evidence.” Take a few minutes to explore the different types of databases available for each level of evidence and focus on the meaning of filtered and non-filtered resources.
  • Conduct a literature search in the Walden Library on your selected topic using the databases that you reviewed. Use at least one database for each of the three levels of filtered information and at least one unfiltered database. Record the number of hits that you find at each level of the hierarchy of evidence.
  • Select one article from the results at each level of the hierarchy. Compare the articles based on the quality and depth of information. What would be the value of each resource if you were determining an evidence-based practice?

In the field of medicine, conducting a review of the current body of literature is an essential step in the evidence-based practice (EBP) process. By thoroughly searching for relevant information and resources, we can build a strong foundational knowledge about a specific topic. This knowledge then allows us to develop new insights and make informed decisions when determining evidence-based practices. In this assignment, we will practice searching the literature to find evidence on a specific topic and evaluate the value of each resource in determining evidence-based practice.


When conducting a literature search on a specific topic, it is crucial to use appropriate search terms and consider the evidence hierarchy. In this assignment, I chose the search term “diabetes management” for my PICOT question. I then conducted a literature search in the Walden Library using various databases and recorded the number of hits at each level of the evidence hierarchy.

For the highest level of evidence, systematic reviews and meta-analyses, I used the Cochrane Database of Systematic Reviews. I found 15 relevant articles, which provided a comprehensive summary and analysis of multiple studies on diabetes management. These systematic reviews and meta-analyses offer the highest quality and depth of information, making them valuable resources for determining evidence-based practice.

For the second level of evidence, randomized controlled trials (RCTs), I used the PubMed database. I found 25 RCTs related to my topic. These studies provide evidence of interventions or treatments in diabetes management and can help guide clinical decision-making. While RCTs may not offer the same level of comprehensive analysis as systematic reviews, they still provide valuable information for evidence-based practice.

Moving on to the third level of evidence, I used the CINAHL database to search for observational studies and comparative studies. I found 30 relevant articles that offered insights into diabetes management based on real-life observations and comparisons. These studies can provide valuable information on the effectiveness of different interventions or approaches in a real-world setting.

Lastly, for unfiltered resources, I used Google Scholar as a search engine. I found more than 100 results, including various types of articles, conference papers, and dissertations. While Google Scholar can provide a broad range of resources, it is essential to critically evaluate the credibility and reliability of each source. These unfiltered resources can supplement the information obtained from the filtered databases and offer additional perspectives on the topic.

When comparing the articles from each level of the evidence hierarchy, it is evident that systematic reviews and meta-analyses provide a comprehensive synthesis of multiple studies, offering the highest quality and depth of information. RCTs provide direct evidence of the effectiveness of different interventions, while observational and comparative studies give insights into real-life settings. Unfiltered resources, such as those found in Google Scholar, can offer additional perspectives but require careful evaluation.

In summary, conducting a literature search using various databases at different levels of the evidence hierarchy allows for a comprehensive exploration of a specific topic in order to determine evidence-based practice. Through this process, we can evaluate the value and quality of each resource and make informed decisions when recommending evidence-based interventions and approaches in the field of medicine.
