Literature Searches
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.
Practice searching the literature to find evidence on a specific topic.
- 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?
Write a summary of your search. Describe what topic you selected, the search term(s) that you used, and the number of results found at each level of the hierarchy. Compare the types of information found in the articles from different levels and the value of the information from each level. Highlight a useful tip that you could share with your colleagues about conducting an effective literature search.

NURS 5052/NURS 6052: Essentials of Evidence-Based PracticeCourse Project OverviewEvidence-based practice involves a great deal more than simply reading nursing periodicals on a regularbasis. Nurses can take a more proactive approach to evidence-based practice by identifying authenticproblems and concerns, and then using that to guide their inquiries into current research. In this way,nurses can connect the results of relevant research studies to their nursing practice.For the Course Project, you identify and apply relevant research to a specific nursing topic or problem.You begin by formulating an answerable question that is relevant to nursing and evidence-based practice.In later weeks of this course, you continue the course project by conducting a literature review and thendetermining how the evidence from the literature can be applied to nursing practice.Before you begin, review this document, which contains information about all three parts of the CourseProject.Note:This Course Project will serve as thePortfolio Assignmentfor the course. In addition tosubmitting portions of this Project in Weeks 2 and 5, you will turn in all three deliverables inWeek 10.Course Project: Part 1–Identifying a Researchable ProblemOne of the most challenging aspects of EBP is to actually identify the answerable question.—Karen Sue DaviesFormulating a question that targets the goal of your research is a challenging but essential task. Thequestion plays a crucial role in all other aspects of the research, including the determination of theresearch design and theoretical perspective to be applied, which data will be collected, and which toolswill be used for analysis. It is therefore essential to take the time to ensure that the research questionaddresses what you actually want to study. Doing so will increase the likelihood of obtaining meaningfulresults.In this first component of the course project, you formulate questions to address a particular nursing issueor problem. You use the PICOT model—patient/population, intervention/issue, comparison, and outcome—outlined in the weekly Learning Resources to design your questions.To prepare:Review the article, “Formulating the Evidence Based Practice Question: A Review of theFrameworks,” found in the Learning Resources for Week 2. Focus on the PICOT model forguiding the development of research questions.Review the section beginning on page of the course text, 75 titled, “Developing and RefiningResearch Problems” in the course text, which focuses on analyzing the feasibility of a researchproblem.Reflect on an issue or problem that you have noticed in your nursing practice. Consider thesignificance of this issue or problem.Generate at least 5 questions that relate to the issue that you have identified. Use the criteria inyour course text to select one question that would be most appropriate in terms of significance,feasibility, and interest. Be prepared to explain your rationale.Formulate a preliminary PICOT question—one that is answerable—based on your analysis.

this question?Note:Not all of these variables may be appropriate to every question. Be sure toanalyze which are and are not relevant to your specific question.Using the PICOT variables that you determined for your question, develop a list of at least 10keywords that could be used when conducting a literature search to investigate current researchpertaining to the question.To complete:Write a 3- to 4-page paper that includes the following:A summary of your area of interest, an identification of the problem that you have selected, andan explanation of the significance of this problem for nursing practiceThe 5 questions that you have generated, and a description of how you analyzed them forfeasibilityYour preliminary PICOT question and a description of each PICOT variable relevant to yourquestionAt least 10 possible keywords that could be used when conducting a literature search for yourPICOT question and a rationale for your selectionsPart 1 of the Course Project is due byDay 7ofWeek 2. It will also be a component of yourPortfolioAssignmentfor this course, which is due byDay 7ofWeek 10.Reference:Davies, K. S. (2011).

Retrieved fromhttps://ejournals.library.ualberta.ca/index.php/EBLIP/article/viewFile/9741/8144Course Project: Part 2—Literature ReviewThe literature review is a critical piece in the research process because it helps a researcher determinewhat is currently known about a topic and identify gaps or further questions. Conducting a thoroughliterature review can be a time-consuming process, but the effort helps establish the foundation foreverything that will follow. For this part of your Course Project, you will conduct a brief literature review tofind information on the question that you developed in Week 2. This will provide you with experience insearching databases and identifying applicable resources.To prepare:Review the information in Chapter 5 of the course text,focusing on the steps for conducting aliterature review and for compiling your findings.Using the question that you selected in your Week 2 Project (Part 1 of the Course Project), locate5 or more full-text research articles that are relevant to your PICOT question. Include at least 1systematic review and 1 integrative review if possible. Use the search tools and techniquesmentioned in your readings this week to enhance the comprehensiveness and objectivity of yourreview. You may gather these articles from any appropriate source, but make sure at least 3 ofthese articles are available as full-text versions through Walden Library’s databases.Read through the articles carefully. Eliminate studies that are not appropriate and add others toyour list as needed. Although you may include more, you are expected to include a minimum offive articles. Complete a literature review summary table using theLiterature Review SummaryTable Templatelocated in this week’s Learning Resources.© 2016 Laureate Education Inc.2
