The Assignment (Evidence-Based Project)

Part 3: Advanced Levels of Clinical Inquiry and Systematic Reviews

Create a 6- to 7-slide PowerPoint presentation in which you do the following:

Identify and briefly describe your chosen clinical issue of interest.
Describe how you developed a PICO(T) question focused on your chosen clinical issue of interest.
Identify the four research databases that you used to conduct your search for the peer-reviewed articles you selected.
Provide APA citations of the four peer-reviewed articles you selected.
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. Be specific and provide examples.

Below is my discussion posting that this powerpoint is based from. My PICOT question is: How does the use of high dose vaccine compare to the standard dose vaccine prevent the risk of influenza hospitalization in the 65 and older population?

At the start of the 2018 to 2019 Influenza season, primary care clinics begin administering influenza vaccines to their patients. There was a recent debate about where the standard vaccine was sufficient enough for the 65 and older population in preventing the risk of developing Influenza leading to hospitalization. This lead to the PICOT question development of: How does the use of high dose vaccine compare to the standard dose vaccine prevent the risk of influenza hospitalization in the 65 and older population? In the first search, the Science Direct database was chosen. Science Direct was accessed through the Walden University Library and includes 2,500 scholarly journals and 39,000 books of life and physical sciences, medicine, and humanity to search from (Elsevier, n.d.-b). The search terms that were used in this database included 65 and older population, high dose influenza versus standard vaccine effectiveness, and prevent hospitalization. There were 1,703 results from this search. To refine the search results more; peer-reviewed articles, and the years 2018 to 2019 were selected. This brought the search results down to 47.

The second database used was ProQuest Nursing & Allied Health Source. This database was accessed through the Walden Library. The Walden University Library defines this database to include abstracts and indexing that covers nursing, allied health, alternative and complementary medicine, and dissertations (n.d.-a). The same search terms were placed in the search engine and resulted in 570 articles. To refine my search more, full text, peer-reviewed, and the last five years were selected. The search results were narrowed down to 54 articles.

Boolean term can help “create more precise and powerful searches with a higher percentage of relevant results” (Walden University, n.d.-b). With both database searches, the addition of Boolean operators narrowed down the articles to more recent articles that can provide better resource information for evidence based practice research.

Some strategies that can be used to increase the rigor and effectiveness of a database search include picking appropriate databases to your subject. For example, ProQuest has different databases that include ProQuest Central, ProQuest Dissertations & Theses Global, ProQuest Health & Medical Collection, and ProQuest Nursing & Allied Health Source. The ProQuest Nursing & Allied Health Source was selected in this search due to the nursing subject. Another strategy to “increase that the best evidence is not missed is to use keyword searching, subject heading searching, and title searching” (Melnyk & Fineout-Overholt, 2018, p. 67). For example, the Science Direct database includes all three of these search categories with the addition of year, author, and the author affiliations (Elsevier, n.d.-a). Two other strategies that can be used is the thesaurus and truncation. The thesaurus will provide synonyms related to the keywords used for the search (Melnyk & Fineout-Overholt, 2018, p.69). For example, the synonyms to “effect” include reaction or development. Truncation will provide different versions of a certain word with an application of an asterisk. For example, nurs* will find nurse, nurses, or nursing.
