CINAHL: An Overview

What is CINAHL?

CINAHL stands for the Cumulative Index of Nursing and Allied Health Literature. It is a database (a collection of articles, books and other electronic information), through which you can locate literature on nursing, biomedicine, health sciences librarianship, alternative/complementary medicine, consumer health and 17 allied health disciplines.

How do I access CINAHL?

You can access CINAHL via the Library's homepage, as shown in the image below.

Steps to a Successful Search

The CINAHL Search Screen

The search screen below is the starting point for all CINAHL database searches. The entire screen is divided into three sections. The top section (1) has the search boxes where search terms can be entered. The middle section (2) allows the searcher to select different options to apply to a search. The bottom section (3) displays all the limiters the searcher can apply to a search strategy.

Note:  The search defaults to Suggest Subject Terms (immediately above the search box).  If you want to search by keywords (natural language, as in a Google search) just uncheck that box.  You will need to uncheck it every time you do a search.


Searching with CINAHL

To begin searching, type a subject term into the first search box on the screen. Click Search.

The next screen displays a list of CINAHL subject headings for the term you entered. This list allows you to select the most relevant term for your search. In most instances, the most relevant term will be at the top of the list.

The Explode and Major Concept columns give options for broadening and/or narrowing the search. The Explode box, when available, will include search terms that are more narrow for the term pain in the set of results it retrieves. Major Concept retrieves articles in which a significant portion of the article is devoted to that term. Once you have determined whether or not to check the Explode or Major Concept column, select the box in front of the term pain, and click Search Database at the right side of the screen.

The results from the your first search are displayed on the screen. To add a second subject to the search, click the clear button. Then type your other keyword in the box and click Search.


Combining Searches

Select any relevant terms and click "Search database." Once viewing your results, click Search History located below the trio of search boxes.

Both searches are displayed as lines S1(first search term) and S2 (second search term). To find the articles that discuss both subjects, first clear the search box near the top of the screen. Then combine S1 with S2 by checking the box in front of each set and clicking the Search with AND button.                                             


(S1 and S2) will appear in the search box, and the results of that search will appear in your Search History.

Scroll down the page to view your search results.

Limiting Results

Users can limit the amount of results generated by a search by setting Limits. Limits can be found on the search results screen, once a search has been completed.

On the left side of the screen, users can limit by Publication Type, Subject Heading, Publication Year, Age, Gender, etc. The limits shown at left can be expanded and contracted by using the arrow icons at the top of each section.

Moving Citations to RefWorks

That's it!  You now have citations that match your search criteria.  At this point, you probably want to add your citations to RefWorks, or another citation management system.  Simply follow the steps below:

1. Perform your search using the Ebsco CINAHL database. Place items to send to RefWorks in the Ebsco folder by clicking the blue folder icon next to each article.

2. Click the Folder icon to display the results in the folder.

3. Select individual references to export or check the Select/Deselect All box at the top to choose all references.

4. Click Export in the right-hand column.

5. Select Direct Export to RefWorks in the Save Citations to a File Formatted for Section.

6. Click the Save button.

7. In RefWorks, click the View Last Imported Folder button.
