NR 265: Evidence Based Professional Nursing Practice: Databases

Nursing databases: click each tab for a link to the database and more search tips.

Start with one or two keywords, then combine concepts one at a time.  Do not add limiters (date, article type, etc.) until you're sure your keywords are productive.

  • Databases use Boolean logic, which means you can combine terms using the words AND and OR to explore the literature more strategically. 
  • Use truncation to include variant endings: therap* = therapy OR therapies OR therapeutic
  • Use quotation marks to bind keywords into a phrase like "fetal alcohol syndrome"
  • Use search history or advanced search to review previous searches and combine them to build new ones

Use controlled vocabulary to refine and focus results.  Many articles have standardized descriptive terms assigned to them so you can easily find related articles.

  • MeSH tutorial (Medical Subject Headings 3-minute video)
    • Most health sciences databases offer MeSH search options
    • CINAHL uses Subject Terms instead of MeSH terms

  Did you find one really good article, but you're having trouble finding a second one?

  Locate the article description in CINAHL, then click Find Similar Results (it's on the left).

  • Recommended limiters (click "show more" under the date range limiter bar to the left of your results list):
    • Published date: adjust range to limit to past 5 years
    • English language (checkbox)
    • Research article (checkbox)
      • This limiter does not necessarily limit to research study articles, but it does eliminate content that is not research at all (newsletters, book reviews, etc.)
    • Journal subset: Core Nursing
      • Select this limiter for results published only in scholarly (peer reviewed) nursing journals
      • Ursuline Library has online full-text access to almost all of the journals in CINAHL's Core Nursing collection
  • Do not overuse limiters! Sometimes they don't do what you think they will do. For example, the "Evidence-Based Practice" limiter in CINAHL eliminates most primary research articles and limits results to a small collection of highly specialized journals.
  • Two ways to select Subject Terms (content-focused controlled vocabulary):
    1. check the box above the search bar and enter keywords, or
    2. find an article by keyword and then click on highlighted Subject Terms in the article's full description
  • Use search history to review and combine searches
  • Recommended limiters (click "show more" under the date range limiter bar to the left of your results list):
    • Published date: adjust range to limit to past 5 years
    • English language (checkbox)
  • Do not overuse limiters!
  • Two ways to select MeSH Terms (content-focused controlled vocabulary):
    1. check the box above the search bar to Suggest Subject Terms and enter keywords, or
    2. find an article by keyword and then click on highlighted MeSH Terms in the article's full description
  • Use search history to review and combine searches
  • everything in Medline is also in PubMed, but PubMed also includes books and other resources from the National Library of Medicine
  • even though there is significant overlap between PubMed and Medline, search results will differ because the databases work differently

Other PubMed tips:

  • Click Advanced under the PubMed search bar to view your search history and combine searches using the search builder
  • PubMed uses automatic term mapping, which means your keywords will be matched to relevant MeSH terms
    • see "Search details" on the right side of your result list to see how PubMed executed your search
  • apply filters on the left side of your result list to narrow results to the past 5 years
    • to limit by language, click "show additional filters," select the checkbox for Languages, and click "Show"
    • then apply the English limiter to your result list by clicking on it
