Let's begin with a brief review.

What is CINAHL?

CINAHL is the largest and most in-depth nursing research database. This licensed online source for high quality nursing and allied health article citations includes some full text articles links.

The abbreviation stands for the Cumulative Index to Nursing & Allied Health Literature.

CINAHL Plus with Full Text provides:

  • full text for 734 journals
  • indexing for 5,000 journals in the fields of nursing and allied health
  • 4,300,000 records
  • 1930's-present
  • 55% of the citations are not in PubMed/MEDLINE.

Why use CINAHL?

This tool provides citations for:

  • nursing dissertations
  • full text CEUs
  • selected conference proceedings
  • standards of practice
  • educational software
  • audiovisuals, books
  • book chapters

CINAHL provides full text for:

  • evidence-based care sheets
  • quick lessons
  • clinical innovations
  • critical paths
  • drug records
  • research instruments
  • clinical trials. 

It also includes reviews and protocols from the Cochrane Database of Systematic Reviews and publications from the National League for Nursing and the American Nurses' Association.

Library online article tools provide greater flexibility in refining search results.  The tool is already focused on the topic of nursing, so fewer unrelated articles will appear in the results of a search.

How Do I Access CINAHL

From the Library homepage:

1. Choose Databases, then enter CINAHL  

Overview of the Searching Process

The following slides will move you through the searching process. You will:

1. Determine the research question.

2. Enter one subject/topic/concept at a time.

3. Explode the subject if this option exists.

4. Add relevant subheadings.

5. Search for the next subject headings; repeat steps 1-3 until all subjects have been entered.

6. Combine subjects using OR, AND.

7. Focus using the Edit search feature to limit to peer review, age groups, etc.

8. View the results.

9. Try different combinations or additional subject terms if not satisfied with the results.

Chapter: Determine the Research Question

Step 1: What is the research question?

  • Often the hardest step is determining the research question. 
  • Write the question down as one simple sentence.
  • For example: Do air beds help prevent pressure ulcers?

 

Subject Searching

1 of 4

Subject headings are standardized terms that describe a concept. They help you find articles about topics that can be expressed in many ways.

For Example: Cancer can be described in various ways, including malignancy, carcinoma, melanoma, breast cancer, etc.

With all these possible terms to choose from, how do you know which to search on?

In CINAHL, the subject heading for cancer is Neoplasms. By searching on Neoplasms, you'll find articles about this topic regardless of how an author may have referred to it.

Tip: Read the Scope note to learn how this subject is used in CINAHL. Scope notes are found in the third column to the right of each subject heading.

Subject Searching

2 of 4

To begin searching for articles on a topic, make sure that the Suggest Subject Terms box is checked. This allows the computer to help you choose a more exact subject heading.

Subject Searching

3 of 4Step 2: Enter each concept one at a time and use the subject heading suggested by the computer.

Enter decubitus ulcers in CINAHL. 

Instead of decubitus ulcers, CINAHL tells us to use?

Subject Searching

4 of 4

Click on the underlined CINAHL Heading, Pressure Ulcer.

You are now in the Tree View for this term.

The Tree View shows broader and narrower terms for Pressure Ulcer.

Heel Ulcer, which is indented under Pressure Ulcer, is a narrower term of this subject heading.

Exploding

1 of 2Step 3: Explode subject heading(s) for a more comprehensive search.

CINAHL Subject Headings are arranged in a hierarchy.
The Explode feature lets you select the term, plus any terms indented underneath it.

If a term has a "+" next to it, then it also has a set of "children" term indented under the "parent" or broader term.  These will also be included in the results of an exploded search.

Check the Explode box for pressure ulcer - it is the first column to the right of the subjects.  This will search for all indented/narrower subjects:


 explode

Rule of Thumb: ALWAYS EXPLODE!!

Can pressure ulcer be exploded?

Exploding

2 of 2

If pressure ulcer is exploded, two narrower terms will also be searched: heel ulcer AND deep tissue injury.

 

Subheadings

Step 4. Add relevant subheadings.

Subheadings are qualifiers used in conjunction with subject headings. There are 68 topical subheadings that can be linked to CINAHL subject headings. Examples of subheadings are: adverse effects, diagnosis, or prevention and control. 

Click the yellow "call out" image to see a definition of how this term is used.

Subheadings

Not all subheadings can be used with all subject headings; for example, the subheading /etiology is meaningless linked to the subject heading NURSING PROTOCOLS.

Our question implies we are looking for ways to prevent pressure ulcers. 

What subheading would you attach to pressure ulcers?

Choose the correct subheading and link it to pressure ulcers.  Click on Search Database.

Explanation of Major Concept

Chapter: Continue to Add Subject Headings, One at a Time

Step 5: Add the next subject headings; repeat until all subjects have been found.

Enter air bed.  Resulting list gives two possible subject headings.  If you are uncertain as to the most relevant subject, consider searching both using OR.

Combining Results

Step 6. Combine subjects using AND, OR.

After all the subjects have been searched, the next step is to combine the results using AND, OR.

Boolean Operators Explained

Let's say that we ran a search for pressure ulcer OR decubitus ulcer and got 2,140 results.  What would happen if we changed this search to pressure ulcer AND decubitus ulcer?

Combine your two concepts: pressure ulcer; air bed.  To combine subjects, use the boxes to the left of each result.  Then click Search with AND.

How many articles did you find?

Step 8: Do you like the results?

Each record will include the citation information for the individual source and a link to full text if it is available

The citation includes information about the:

  • title
  • author
  • name of the journal or publication
  • date.

Click on the title of the result to see more information, such as an author provided abstract, and a list of Major and Minor Subjects for this article.

Tip: If you click on one of these subjects, a new search will be conducted just for that topic.

You may want to start a list of these subjects so you can keep track of the words you are using for searching.

Tip: Use the Delete Searches button to remove searches from your search history.

Question 3: Combining Subjects to Describe a Concept

Your patient is an adolescent just diagnosed with type 2 diabetes.  He needs to learn more about dietary changes, the role of exercise and how to give himself injections.  As always, peer reviewed articles are preferred.

NB:  Subjects that are qualified by [Iowa NOC] or [Saba CCC ] are not articles on the subject, but rather articles about this particular nursing classification scheme.  Avoid these red herrings!

Use or to combine the subjects for diet, exercise, and injections.
