Search & Browse FAQs

How can I find guidelines on a specific topic?

You can type your search term in the search box accessible in the masthead of all NGC Web pages to quickly search the database. You can also browse the NGC database by Clinical Specialty, MeSH Topic (Disease/Condition, Treatment/Intervention, Health Services Administration) or Organization.

The About Search & Browse page contains useful tips on how to search the NGC database for guidelines of interest. You can also use facets (e.g., Clinical Specialty, Intended Users, Guideline Category) from the search results page to perform refined searches of the NGC database.

How can I limit my search results to those guidelines that include an evidence table and/or evaluation of the level of evidence for each recommendation?

The search results page allows users to limit their search of the NGC database by the following guideline methodology components:

  • Methods Used to Analyze the Evidence
  • Methods Used to Assess the Quality and Strength of the Evidence
  • Methods Used to Formulate the Recommendations

Is NGC searching the complete, full-text guideline for my search terms?

No. The main search engine searches the contents of the guideline summary as well as its metadata (i.e., UMLS concepts). Once on a search results page, a user can further narrow their result set by using the facet options. For more information on searching guidelines, see About Search & Browse.

Is the NGC search engine case sensitive?

No. NGC searches do not recognize the difference between uppercase and lowercase letters. For more information on searching, see About Search & Browse.

My search returned a results page stating "no results were found." Why doesn't NGC have any guidelines on my topic?

Your search may not yield content matching the criteria you specified. This can happen for several reasons:

  • You may have misspelled a word.
  • Your search may be too specific. If you are using the search box, try using more general terms.
  • NGC may not yet have the guideline you are seeking. Content is constantly changing, with new guidelines added frequently. Bookmark this site and make sure to check back often. To be notified by e-mail on a weekly basis when new and updated content is added to the site, see the Subscribe to Weekly E-mail page.
