A literature review is one of the most important and most challenging components of a nursing dissertation or research assignment. In UK nursing and healthcare programmes, the literature review serves not simply as a summary of existing research—it is a critical synthesis of the evidence base that positions your own research within the scholarly conversation of your field and demonstrates your ability to evaluate, compare, and draw conclusions from a body of clinical and scientific knowledge.
Types of Nursing Literature Review
UK nursing programmes distinguish between different types of literature review, and understanding which type your assignment requires is the first step to completing it successfully.
A narrative literature review provides a broad survey and synthesis of existing research on a topic. It is less systematic than a formal systematic review in its search and selection procedures, but still requires rigorous critical analysis of sources. Narrative reviews are most common in undergraduate dissertations and shorter academic assignments where a comprehensive systematic review would be impractical given word count constraints.
A systematic literature review follows a highly structured protocol: a defined research question (often formulated using the PICO framework—Population, Intervention, Comparison, Outcome), a reproducible search strategy across multiple databases, explicit inclusion and exclusion criteria, critical appraisal of each included study, and a structured synthesis of findings. Systematic reviews are the gold standard for evidence-based healthcare research and are commonly required in postgraduate nursing dissertations.
A scoping review maps the existing evidence on a broad topic without necessarily synthesising findings as quantitatively as a systematic review. It is particularly useful for identifying research gaps, clarifying key concepts, and examining the scope of a literature in a new or emerging field.
Conducting Your Search: Databases and Search Strategy
A robust database search is the foundation of an effective nursing literature review. The key databases for nursing and healthcare literature include CINAHL (Cumulative Index to Nursing and Allied Health Literature), Medline (via PubMed or Ovid), EMBASE, PsycINFO (for mental health and psychology), and the Cochrane Library (for systematic reviews and randomised controlled trials). Most UK university library services provide access to all of these databases through Athens or Shibboleth login.
Develop a systematic search strategy using Medical Subject Headings (MeSH terms) and free-text keywords related to your topic. Combine terms using Boolean operators: AND narrows your search (“falls prevention AND older adults AND hospital”), while OR broadens it (“falls prevention OR fall reduction”). Document your search terms and the number of results produced by each search—this documentation forms part of your methodology and is required for transparent reporting.
Apply inclusion and exclusion criteria consistently to the results of your searches. Common inclusion criteria in nursing literature reviews specify a publication date range (typically the last ten years, though some topics may justify a longer window), language (English-language sources only, in most UK dissertations), publication type (peer-reviewed journal articles, systematic reviews, clinical guidelines), and participant population (studies involving the specific patient group relevant to your research question).
Critically Appraising and Synthesising the Literature
Critical appraisal is the process by which you evaluate the methodological quality of the studies you have identified. In nursing, the CASP (Critical Appraisal Skills Programme) checklists are the most widely used appraisal tools and are available free from the CASP website. Different checklists are designed for different study types, including randomised controlled trials, cohort studies, qualitative research, systematic reviews, and diagnostic test studies.
After appraising each study, synthesise the findings thematically. Rather than summarising each paper in sequence (a common but weak approach), identify the themes, patterns, and debates that emerge across the literature and organise your review around these. Each theme becomes a section of your literature review, with individual studies used as evidence to support or complicate the points you are making about the theme.
Identify and acknowledge the limitations of the evidence base as well as its strengths. A literature review that only summarises positive findings presents a distorted picture; strong reviews engage honestly with methodological weaknesses, conflicting findings, and gaps in the research. Identifying these gaps is particularly important in a dissertation literature review, as the gap you identify should directly motivate your own research question.
If you need expert guidance on conducting and writing a nursing literature review that meets the standards of your programme, professional academic support from specialists with nursing research expertise can help you develop your search strategy, apply critical appraisal frameworks, and produce a synthesis that is both rigorous and clearly written.
