Evan JohnEvery clinical practice guideline, nursing protocol, and patient care improvement initiative rests on one critical process: the systematic review of existing evidence. Yet for many nursing students, the literature review is one of the most challenging and misunderstood components of academic and professional work.
If you have ever stared at a blank document unsure where to begin, searched databases and felt overwhelmed by thousands of results, or struggled to bring your findings together into a coherent argument, this guide is written for you.
Knowing how to write a nursing literature review is not simply an academic requirement. It is a clinical skill. It trains you to evaluate evidence critically, recognise gaps in current practice, and apply research findings meaningfully to patient care.
This comprehensive guide walks you through every stage of the process, from understanding what a literature review is, to structuring, writing, and refining a submission that meets the standards of nursing education and professional practice.
A nursing literature review is a structured, critical analysis of existing published research on a specific clinical or healthcare topic. It is not simply a summary of articles. A literature review synthesises evidence, identifies patterns and contradictions across studies, highlights gaps in the current body of knowledge, and builds a scholarly argument.
In nursing, literature reviews serve several purposes:
A nursing literature review differs from a systematic review in scope and methodology. Systematic reviews follow a rigorous, highly structured protocol with explicit inclusion criteria and statistical methods such as meta-analysis. A traditional or narrative literature review, more commonly assigned in nursing school, is broader and allows for interpretive synthesis of evidence.
Before you begin writing, you need to understand which type of literature review your assignment or purpose requires.
This is the most common type assigned in undergraduate and postgraduate nursing programmes. It provides a broad overview of research on a topic, organising findings thematically or chronologically. It allows for critical interpretation but is less rigorous in its search methodology than a systematic review.
This type follows a strict, reproducible protocol. It uses predefined inclusion and exclusion criteria, comprehensive database searches, and formal quality appraisal tools such as the CASP (Critical Appraisal Skills Programme) checklist. It is typically required for advanced nursing research, dissertations, and published academic work.
This approach combines both quantitative and qualitative research to produce a broader understanding of a clinical issue. It is particularly useful when exploring complex nursing phenomena that involve both measurable outcomes and patient or nurse experiences.
A scoping review maps the existing evidence on a topic to identify what types of research have been done, rather than synthesising findings to answer a specific clinical question. It is often used to identify gaps before undertaking a full systematic review.
A well-defined topic is the single most important starting point. Broad topics generate unmanageable volumes of literature. Narrow topics may yield insufficient sources.
Use the PICOT framework to structure your clinical question before beginning your search. Identify your population, intervention, comparison, outcome, and timeframe. This directly translates into the search terms you will use in academic databases.
For example, rather than writing a literature review on “pain management in nursing,” define your focus as: “Non-pharmacological pain management strategies in adult postoperative patients in surgical wards.”
Searching the literature effectively requires using the right databases and the right search strategy.
Recommended databases for nursing literature reviews include:
Use Boolean operators to refine your search:
Use MeSH (Medical Subject Headings) terms when searching PubMed for more precise results. Apply filters such as publication date, peer-reviewed sources, full-text availability, and language to manage your results.
Before reviewing your search results, define clear criteria for which studies you will include and which you will exclude. This ensures transparency and academic rigour.
Common inclusion criteria in nursing literature reviews:
Common exclusion criteria:
Document your inclusion and exclusion criteria clearly. This is a required section in most formal literature review assignments.
A nursing literature review is not a list of article summaries. Critical appraisal means evaluating the quality, validity, and relevance of each source before deciding how much weight to give it in your argument.
Use recognised appraisal tools appropriate to each study design:
When appraising each source, consider:
Once you have selected and appraised your sources, organise them into themes. Do not structure your review article by article. Instead, identify the main themes, patterns, or concepts that emerge across the literature and group your studies accordingly.
For example, a literature review on nurse burnout might be organised under themes such as: contributing factors, impact on patient safety, organisational interventions, and individual coping strategies.
Creating a synthesis matrix or concept map before writing can help you visualise the relationships between studies and plan your argument effectively.
A well-structured nursing literature review follows a clear format.
Begin with a brief overview of your topic and its clinical significance. State the purpose of your literature review and your guiding research question. Describe your search strategy, databases used, and inclusion criteria. End with a brief outline of how the review is structured.
Each thematic section should begin with a clear topic sentence introducing the theme. Then synthesise the evidence from multiple studies, comparing and contrasting findings. Discuss areas of agreement, contradiction, and uncertainty across the literature. Always critically evaluate rather than simply describe.
Use phrases that indicate synthesis and critical analysis, such as:
Cite every source using the referencing style required by your institution, typically APA 7th edition, Harvard, or Vancouver in nursing programmes.
After presenting your thematic sections, discuss the gaps you have identified in the existing literature. This demonstrates higher-order critical thinking and is often a criterion in marking rubrics.
Gaps may include:
Summarise the key themes and findings of your review. Restate the clinical significance of the topic. Recommend directions for future research. Avoid introducing new information in the conclusion.
Compile a complete, accurately formatted reference list using your required citation style. Use reference management tools such as Zotero, Mendeley, or EndNote to organise citations and generate your reference list automatically.
Being aware of the most frequent errors will help you produce higher quality work and avoid losing marks.

How many sources should a nursing literature review include? The number depends on the scope of your assignment and academic level. Undergraduate literature reviews typically include 10 to 20 sources. Postgraduate and doctoral reviews may include 30 to 60 or more. Always refer to your assignment brief for specific guidance. Prioritise quality and relevance over quantity.
How recent should my sources be for a nursing literature review? As a general rule, sources should be published within the last five to ten years to ensure clinical currency. However, seminal works, foundational nursing theories, and landmark studies may be included regardless of publication date, provided their inclusion is justified.
What is the difference between a literature review and an annotated bibliography? An annotated bibliography lists sources with a brief summary and evaluation of each one individually. A literature review synthesises multiple sources thematically to build an argument or answer a clinical question. The two are structurally and academically distinct.
Can I use websites as sources in a nursing literature review? In most cases, websites are not appropriate sources for academic nursing literature reviews. Stick to peer-reviewed journal articles. Exceptions may include authoritative organisational publications from bodies such as the World Health Organization, the National Institute for Health and Care Excellence, or the Centers for Disease Control and Prevention, provided they are cited appropriately.
How do I avoid plagiarism in a nursing literature review? Paraphrase all source material in your own words and cite every idea, finding, or argument that originates from another author. Use plagiarism detection software such as Turnitin before submission. Never copy and paste text from any source, including articles, clinical guidelines, or online resources.
Mastering how to write a nursing literature review is a skill that pays dividends throughout your entire nursing career. It sharpens your ability to evaluate clinical evidence, strengthens your academic writing, and equips you to make research-informed decisions at the bedside.
Approach each review as an opportunity to deepen your understanding of a clinical topic, contribute to the body of nursing knowledge, and develop the critical thinking that defines excellence in professional nursing practice.
Start with a focused clinical question, search the right databases, appraise your evidence carefully, and synthesise your findings with clarity and purpose.
