How to Search the CINAHL Database: Step-by-Step Guide for Nursing and Allied Health Research

The Cumulative Index to Nursing and Allied Health Literature (CINAHL) is one of the most important research databases for nursing, public health, and allied health professionals. It provides access to peer-reviewed journals, evidence-based care sheets, clinical guidelines, and dissertations.

Learning how to search the CINAHL database correctly saves time and improves the quality of your research. This guide explains every step, from logging in to refining your search, so you can find relevant and reliable studies for assignments, literature reviews, or clinical practice.

1. Understanding What CINAHL Is

Before you begin searching, understand what CINAHL covers. The database is managed by EBSCO Information Services, and it indexes thousands of journals, books, and conference papers related to nursing and allied health.

CINAHL provides full-text access to journals and citations for other publications. It includes materials in subjects such as:

• Nursing and midwifery

• Physiotherapy

• Occupational therapy

• Nutrition and dietetics

• Public health

• Speech and language therapy

• Health information management

The main version is CINAHL Complete, available through EBSCOhost. Some institutions also provide access to CINAHL Plus with Full Text or CINAHL Ultimate, which include expanded journal coverage.

2. Accessing the CINAHL Database

You usually access CINAHL through your institution’s library website. Universities, hospitals, and professional associations often provide login links.

Steps to Access:

1. Go to your library’s Databases or Electronic Resources page.

2. Search for CINAHL.

3. Click the link that says CINAHL Complete, CINAHL Plus, or CINAHL Ultimate.

4. Log in using your institutional username and password.

5. You will be redirected to the EBSCOhost interface.

If you do not have institutional access, you can explore CINAHL through EBSCO’s public search interface (cinahl.com) for limited features. However, full-text content usually requires subscription access.

3. The CINAHL Search Interface

When you open CINAHL, the Basic Search screen appears by default. You will see a search box, a menu bar, and a series of limiters (filters).

The interface is divided into sections:

• Search Box: Where you enter your keywords or phrases.

• Limiters: Options such as Full Text, Peer-Reviewed, Date Range, and Age Groups.

• Navigation Toolbar: Access to advanced search, publications, and search history.

• Result List: Displays article titles, authors, sources, and access links.

You can toggle between Basic Search and Advanced Search. Basic Search is good for quick lookups. Advanced Search gives you more control with field searching, Boolean operators, and subject headings.

4. Planning Your Search

A successful search starts with a clear research question. You need to identify the main concepts and related keywords before you start typing.

For example, if your topic is “the effect of hand hygiene education on infection control among nurses”, identify the main terms:

1. Hand hygiene

2. Education

3. Infection control

4. Nurses

Then think about synonyms and related terms:

• Hand hygiene: handwashing, hand sanitation

• Education: training, teaching, instruction

• Infection control: infection prevention

• Nurses: nursing staff, registered nurses

Writing these out helps you use the database effectively.

5. Using Basic Search

If you are new to CINAHL, start with the Basic Search.

Steps:

1. Enter your main keywords, for example, hand hygiene education infection control nurses.

2. Use quotation marks for exact phrases, like “hand hygiene” or “infection control”.

3. Click Search.

4. Review your results list.

Each result shows the article title, authors, journal name, publication date, and subject headings. You can click the title to open the detailed record.

Example:

If you search “hand hygiene education infection control nurses,” CINAHL might return 500 results. You can then refine them using filters.

6. Using Advanced Search

The Advanced Search option allows for precise searching with Boolean operators, field codes, and CINAHL Subject Headings.

Boolean Operators:

• AND narrows your search by combining terms (hand hygiene AND nurses).

• OR broadens your search (hand hygiene OR handwashing).

• NOT excludes terms (infection control NOT hospital-acquired infections).

Steps for Advanced Search:

1. Click Advanced Search under the search box.

2. You will see multiple rows to enter your keywords.

3. Combine your terms logically:

   • First box: “hand hygiene”

   • Second box: education OR training

   • Third box: nurses OR “nursing staff”

4. Select AND between the rows.

5. Scroll down to apply filters (Full Text, Publication Year, Peer Reviewed).

6. Click Search.

This produces focused and relevant results.

7. Using CINAHL Headings

CINAHL uses controlled vocabulary, known as CINAHL Headings, to index articles consistently. These work like MeSH terms in PubMed.

For example, an article about hand hygiene might be indexed under the CINAHL Heading “Handwashing”.

Using CINAHL Headings helps you find all articles on a topic, even if authors used different words.

How to Use CINAHL Headings:

1. Click CINAHL Headings on the top toolbar.

2. Type your keyword in the search bar (for example, “hand hygiene”).

3. Select the relevant subject heading, such as Handwashing.

4. Check the box Explode to include narrower terms.

5. Check Major Concept if you want to focus on articles where this is the main topic.

6. Click Search Database.

You can then combine these headings with other keywords.

Example:

Search for Handwashing as a CINAHL Heading and combine it with Education using AND. This finds studies on handwashing education programs.

8. Applying Limiters and Filters

CINAHL includes several limiters that help you narrow results to the most relevant materials.

Common Filters:

• Full Text: Shows only articles available in full.

• Peer Reviewed: Restricts to scholarly journals.

• Publication Date: Set a specific date range, such as 2018–2025.

• Publication Type: Choose research articles, evidence-based care sheets, systematic reviews, or dissertations.

• Age Groups: Select Adult, Adolescent, or Child.

• Gender: Male or Female.

• Language: Limit to English or other languages.

Example:

If you want only recent, peer-reviewed studies on hand hygiene education among nurses, apply:

• Peer Reviewed

• Published after 2018

• English language

Then click Update Results.

12. Accessing Full Text Articles

Some CINAHL results provide Full Text directly through EBSCOhost. If the full text is not available, you may see a link like Find It@YourLibrary or Check Access.

If your institution has access to that journal, you can read or download the article. If not, you can:

• Use Interlibrary Loan (ILL) to request the article.

• Search the journal title in your library catalog.

• Look for the article on PubMed Central (PMC) or ResearchGate for open access versions.

Always download the PDF version if available. PDFs retain page numbers and formatting for citation accuracy.

13. Using Evidence-Based Tools

CINAHL provides additional resources that support evidence-based practice.

Key Tools:

1. Evidence-Based Care Sheets: Summaries of best practices on specific clinical topics.

2. Quick Lessons: Short summaries on diseases, procedures, or treatments.

3. Clinical Queries: Predefined filters for specific study types such as therapy, diagnosis, prognosis, or qualitative research.

Example:

If you search “pressure ulcers,” open the Evidence-Based Care Sheet to review best practices in prevention and management.

These tools save time for nurses and students who need reliable, practice-oriented summaries.

14. Searching by Publication

If you need to find articles from a particular journal, use the Publications tab.

Steps:

1. Click Publications on the top menu.

2. Browse or search for the journal title, such as Journal of Nursing Education.

3. Select the journal.

4. Use the search box within the journal page to search its contents.

This is helpful when your instructor asks you to use sources from specific nursing journals.

15. Searching by Author or Title

If you already know part of the article title or the author’s name:

Steps:

1. Use the Advanced Search.

2. Enter the author’s name in the Author (AU) field. Example: Smith J.

3. Enter keywords from the title in the Title (TI) field.

4. Click Search.

This targeted search quickly retrieves specific papers.

16. Using Truncation and Wildcards

Truncation and wildcard symbols help capture variations of a word.

• Truncation: Use an asterisk () to find all forms of a word.
  Example: educat finds education, educator, educating, educational.

• Wildcard: Use a question mark (?) to replace a single character.
  Example: wom?n finds woman and women.

These tools broaden your search and reduce missed results.

17. Refining Your Search Strategy

If you get too many results, narrow them down.
If you get too few, broaden your keywords.

To Narrow:

• Use AND to combine terms.

• Apply Major Subject Heading.

• Limit by date or publication type.

• Select Research Article or Systematic Review.

To Broaden:

• Use OR to include synonyms.

• Remove some limiters.

• Use truncation to capture variations.

Effective searching often involves repeating and adjusting queries until the results are balanced.

18. Managing Search Alerts

CINAHL allows you to create Search Alerts that notify you when new articles match your topic.

Steps:

1. Perform your search.

2. Click Share above your results.

3. Select Create Alert.

4. Log in to your EBSCOhost account.

5. Choose the frequency (daily, weekly, monthly).

This is useful for long-term projects or ongoing professional interests, such as infection control or nursing education.

19. Evaluating the Articles You Find

Not every article is suitable for academic or clinical use. Evaluate each source using criteria such as:

1. Authority: Who is the author? Are they affiliated with a university or hospital?

2. Currency: When was the article published?

3. Evidence Level: Is it a randomized controlled trial, systematic review, or expert opinion?

4. Relevance: Does the study address your question directly?

5. Accuracy: Are the findings supported by data?

High-quality evidence comes from peer-reviewed, recent, and well-designed studies.

20. Comparing CINAHL with MEDLINE

Many researchers use both CINAHL and MEDLINE (via PubMed). They overlap in content but serve different audiences.

Feature	CINAHL	MEDLINE
Focus	Nursing and Allied Health	General Medicine
Platform	EBSCOhost	PubMed / Ovid
Controlled Vocabulary	CINAHL Headings	MeSH Terms
Journals Indexed	5,000+	6,000+
Evidence-Based Tools	Yes	Limited

If you are studying nursing or allied health, start with CINAHL. If your topic includes broader medical subjects, use both databases for a comprehensive review.

21. Common Search Mistakes to Avoid

Many users waste time due to poor search habits. Avoid these common errors:

1. Typing full sentences: Use keywords instead.

2. Ignoring subject headings: These improve accuracy.

3. Not using Boolean operators: They control your search logic.

4. Skipping filters: Filters remove irrelevant material.

5. Failing to save searches: You lose your work after logging out.

6. Relying only on one search: Repeat with new combinations.

Refining your technique improves both speed and precision.

22. Example of a Complete Search
