How to Write a Nursing Literature Review

The full process from review question to databases, Boolean searches, inclusion criteria, citation management and a themed draft.

Updated October 2026 · 7 min read

A nursing literature review is rarely hard because of the writing. It is hard because of everything that should happen before you write.

Choosing databases, running searches that return a manageable set of results, deciding what is in scope and organizing what you find all come first. This guide covers that process end to end. To see what the finished write-up looks like, read the nursing literature review example.

The Literature Review Process in Brief

Start with a focused review question, often your PICOT. Search CINAHL and PubMed (plus Cochrane for existing reviews) with Boolean strings built from your key concepts, and write inclusion and exclusion criteria before you screen.

Save every source to a citation manager, extract key details into a table, then draft by theme rather than by source. Finish with a gap statement that links the evidence to your project.

Step 1: Define the Review Question First

It is tempting to start searching as soon as you have a topic such as "fall prevention". A search that broad returns thousands of results, most of them irrelevant.

Before opening a database, write one or two sentences stating what the review must establish. For a capstone this is usually your PICOT question or a close variant; for a standalone assignment, the prompt sets the scope.

A focused question does two jobs. It tells you what to search for, and later it tells you what to exclude, because an interesting source still does not belong if it does not answer your question.

Step 2: Choose Databases Deliberately

Searching only Google Scholar tends to miss nursing-specific literature and makes your search hard to report. Use two or three subject databases instead.

DatabaseBest forNotes
CINAHLNursing and allied health topicsUsually the primary database for nursing reviews
PubMed / MEDLINEMedical, pharmacological and clinical topicsFree to search; broader than CINAHL; uses MeSH headings
Cochrane LibrarySystematic reviews and trialsCheck first; an existing review can anchor your whole chapter
PsycINFOMental health and behavior changeUseful for patient or staff psychology topics
ERICNursing education and trainingRelevant to staff education interventions

CINAHL plus PubMed is a strong default for most nursing topics. Add a third database only when your topic clearly needs it.

Break your question into its main concepts, usually population, intervention and outcome. List synonyms for each, then combine them with Boolean operators.

Question: fall prevention in hospitalized older adults.

Search string: (fall* OR "fall prevention") AND (elderly OR "older adult*" OR geriatric) AND (hospital* OR inpatient)

Then add: the database's subject headings (CINAHL Headings or MeSH) for each concept, combined with OR alongside the keywords.

Applying Limits

Most databases let you filter by date, language, peer review and study type. Many programs expect sources from the last five to seven years for evidence-based practice work, and some insist on five.

Older landmark studies can still belong if they remain central to the topic. Check your program's rule before relying on them, and record every limit you apply.

Step 4: Set Inclusion and Exclusion Criteria

Write your criteria down before you screen a single result. Deciding case by case leads to inconsistent choices that are hard to defend.

CriterionTypical inclusionTypical exclusion
Publication typePeer-reviewed research and systematic reviewsEditorials and opinion pieces without data
DateWithin your program's windowOlder studies unless they are foundational
PopulationMatches your review population and settingPopulations that do not transfer, such as pediatric studies in an adult review
LanguageEnglish, or translations availableStudies you cannot read in full
FocusAddresses your question or a closely related oneTopically related but off-question

Screen titles first, then abstracts, then full texts. Keep a simple count at each stage; if your review is systematic, these counts feed a PRISMA 2020 flow diagram.

Step 5: Set up Citation Management Early

Retrofitting citations at the end is one of the most time-consuming parts of revision. Set up your system before you start screening.

Step 6: Extract Data into a Table

Read the full text of every included source and record the same details for each. This table becomes the backbone of your synthesis.

ColumnWhat to record
Author and yearFor in-text citation
Design and level of evidenceFor example RCT, cohort, qualitative; level from your program's hierarchy
Sample and settingSize, population and care setting
Key findingsThe results that bear on your question
LimitationsWhat weakens confidence in the findings
ThemeWhere the study fits in your review

Avoid citing from abstracts alone. Abstracts often leave out sample details and limitations, so use your library or interlibrary loan for full texts, or substitute another source.

Appraise as You Extract

Rate each study's level and quality while it is fresh. Many programs use the Johns Hopkins evidence appraisal tools or the Melnyk and Fineout-Overholt hierarchy, so check which one your rubric names and apply it to every source the same way.

Appraisal lets you weigh studies fairly in the draft. A well-run trial and a small pilot can both belong in a theme, but they should not carry equal weight in your conclusions.

Step 7: Organize and Draft by Theme

Read across your table for shared outcomes, agreements, contradictions and gaps. Each strong pattern becomes a theme and a subheading.

  1. Introduction: the problem, why it matters and the review question.
  2. Search methods: databases, terms, limits and criteria, briefly.
  3. Themes: one section per theme, comparing studies within it.
  4. Synthesis and gap: what the evidence shows overall and what remains unanswered.
  5. Conclusion: how the gap leads to your project or recommendation.

Discuss method differences where they might explain different results. That comparison is what lifts a themed review into a real synthesis.

Planning Your Time

Students often budget for writing and forget that searching and reading take longer. A rough split for a capstone-length review looks like this.

StageShare of total timeOutput
Question and search strategyAbout 10%Review question, concept table, search strings
Searching and screeningAbout 20%Included sources with counts at each stage
Full-text reading and extractionAbout 30%Completed extraction table
Theming and outliningAbout 10%Themes, subheadings and gap statement
Drafting and revisingAbout 30%Finished, formatted review

If your deadline is close, protect the reading and extraction stage. A review drafted from skimmed abstracts is the hardest kind to fix later.

Keep a Search Log

Record the date, database, exact string, limits and number of results for every search. It takes a minute per search and lets you write your methods paragraph accurately.

Common Mistakes and Fixes

MistakeFix
Searching before the question is focusedWrite the review question first, then build the string
Relying on one general search engineUse CINAHL plus PubMed, and check Cochrane
Deciding inclusion source by sourceWrite criteria before screening and apply them consistently
Citation manager set up at the endSave and tag sources from the first search
Writing one paragraph per sourceDraft by theme from your extraction table
Missing an existing systematic reviewSearch Cochrane and filter for reviews before anything else

Frequently Asked Questions

How many sources should a nursing literature review include?

It depends on the assignment. Capstone chapters often use around 15 to 25 sources and shorter course papers fewer, but coverage of your themes matters more than a precise count.

How recent do my sources need to be?

Many programs expect the last five to seven years, and some require five. Foundational studies can be included if they remain central, but check your program's rule first.

Do I need both qualitative and quantitative studies?

It depends on the question. Effectiveness questions rely mainly on quantitative studies, while questions about experiences or barriers need qualitative work, and many reviews use both.

What if I cannot find enough sources on my exact topic?

Broaden one element at a time, such as the population or setting, and discuss your specific group as a gap. Very thin literature may also mean the topic needs adjusting.

Can I cite a study from its abstract?

Avoid it. Abstracts omit details that matter for accurate synthesis, so get the full text or choose another source.

How is a literature review different from a background section?

A background section briefly explains why a topic matters. A literature review is a full, themed synthesis of the evidence and is far longer.

Is my literature review a systematic review?

Usually not. A systematic review follows a registered protocol, a reproducible search and formal appraisal, often reported with PRISMA 2020; most capstone reviews are narrative or integrative.

Which citation manager should I use?

Zotero and Mendeley are both free and work well. Choose one before you start searching, and check its APA 7th output by hand.
