Respondto Your Colleague Providing Further Suggestions On How Their Da

Respond to your colleague providing further suggestions on how their database search might be improved. At least 2 references in each peer responses! My PICO(T) question is; In preschool-age children (P), how does receiving the flu vaccine (I) compare to not receiving the vaccine (C) impact the risk of severe illness or death related to flu (O) during the flu season (T)? The primary databases I used were Pubmed and CINAHL Plus with full text. The search terms I used were; Flu Vaccine; and Children; Effectiveness of Flu Vaccine and Children; Flu Vaccine and Children and School Age; Effectiveness of Flu Vaccine and Statistics and Children.

When I searched CINAHL, there were 1,798 results. I narrowed the search to peer-reviewed articles and changed the dates, so they ranged from 2015 to 2020 to show the most recent articles in evidence-based practice. After adding these Boolean operators, I had 176 peer-reviewed articles. Walden Library (2020), recommends using Boolean terms to create a more precise search with more relevant results. A recent study concluded that it is essential to search at least three different databases to retrieve approximately 90% of all the relevant literature on a subject (Ho, Liew, Ng, Shunmugam, & Glasziou, 2016).

A strategy to increase the rigor and effectiveness of a database search is to use alternative terms. I could try searching alternative words such as “Influenza,” “juvenile,” or “youth” to improve my results. On PubMed, I used the advanced search filters to narrow my search. I clicked to view articles that only studied humans and that were published within the past five years. Another strategy is to utilize a feature on PubMed called Clinical Inquiries. Clinical Inquiry is designed to improve search results by linking the type of question, therapy, diagnosis, or prognosis to a stored search strategy that retrieves the appropriate research methodology (Schardt, 2007). Utilizing all of these techniques will help improve my search results to find the most relevant peer-reviewed articles for my topic.

Your colleague has demonstrated a commendable approach to optimizing database searches for evidence-based research on the effectiveness of the flu vaccine in preschool children. However, there are several additional strategies that could be employed to further refine and enhance the search process, ensuring that the most relevant and high-quality literature is retrieved.

Firstly, expanding the scope of search terms through the use of controlled vocabulary such as Medical Subject Headings (MeSH) in PubMed can significantly improve the quality of results. MeSH terms act as standardized keywords that index articles, providing a thesaurus of biomedical terminology that helps locate articles even if different authors use different phrases (Lukes & Wieck, 2011). For instance, using MeSH terms such as “Influenza Vaccines,” “Pediatric Diseases,” and “Severe Illness” may uncover articles that do not explicitly include keywords like “flu vaccine” but are highly relevant to the research question.

Additionally, the implementation of "field tags" in PubMed and CINAHL searches can increase specificity. For example, limiting searches to the title or abstract fields (e.g., using [tiab] in PubMed) ensures that results are directly related to the specific concepts of interest, reducing extraneous data (Bramer et al., 2018). Combining MeSH terms with keyword searches using Boolean operators can further increase search precision, ensuring a comprehensive yet focused retrieval of pertinent literature. For example, a search could include: (“Influenza, Human”[MeSH]) AND (“Child, Preschool”[MeSH]) AND (“Vaccine Safety”[MeSH]) OR “Effectiveness” in the title or abstract.

Furthermore, the use of citation tracking or snowballing—reviewing references of key articles—can uncover additional relevant studies that may not be retrieved through database searches alone (Gøtzsche, 2011). This manual process can reveal seminal articles, systematic reviews, or meta-analyses that provide high levels of evidence for the effectiveness of the flu vaccine in young children.

Employing similar advanced search strategies across multiple databases is also crucial. For example, Embase, Scopus, and Web of Science could be used in addition to PubMed and CINAHL to ensure a broader scope of literature coverage. According to Bramer et al. (2018), combining databases that index different journals and disciplines reduces publication bias and enriches the evidence base.

In addition, refining inclusion and exclusion criteria based on study quality (such as prioritizing randomized controlled trials and systematic reviews) during the screening process can improve the overall quality of the evidence selected (Higgins et al., 2019). Utilizing tools like the PRISMA flow diagram ensures transparent documentation of search results, duplicates removal, screening, and reasons for exclusion, further strengthening the review process.

In conclusion, by incorporating MeSH heading searches, field tags, citation tracking, cross-database searching, and rigorous screening for methodological quality, researchers can greatly improve the accuracy and relevance of their literature search. These strategies not only maximize relevant evidence retrieval but also bolster the validity and reliability of the resulting research findings.
