Literature reviews are one of the most demanding parts of academic research. Whether you are completing an undergraduate dissertation, a master’s thesis, or a doctoral research project, your ability to identify, evaluate, and synthesise existing studies directly affects the quality of your work. In recent years, the use of PRISMA guidelines for literature reviews has become increasingly important across UK universities because of the growing emphasis on research transparency, reproducibility, and evidence-based academic writing.

If you have come across terms such as PRISMA 2020 checklist, PRISMA flow diagram, or systematic review PRISMA guidelines, you may already know that PRISMA is now considered a gold standard for reporting systematic reviews. However, many students still struggle to understand how to use PRISMA for literature review writing in practice. Some assume it is only suitable for medical research, while others feel overwhelmed by the technical terminology and reporting requirements.
The reality is that PRISMA can significantly improve the structure, clarity, and credibility of your literature review when used correctly. Universities across the UK increasingly encourage students to follow transparent review methods, particularly within health sciences, psychology, business, education, and social sciences. In fact, many departments now expect postgraduate students to include a PRISMA flow diagram and explain their search strategy in detail.
This guide explains the PRISMA framework for literature review writing step by step. You will learn what the PRISMA guidelines are used for, understand the four steps of PRISMA, explore the new PRISMA 2020 guidelines, and see practical examples of how students can apply the framework successfully in dissertations and research projects.
Understanding the PRISMA Framework for Literature Reviews
The PRISMA framework stands for Preferred Reporting Items for Systematic Reviews and Meta-Analyses. It was originally developed to improve the reporting quality of systematic reviews, ensuring that researchers clearly explain how studies were identified, selected, screened, and analysed.
At its core, PRISMA promotes transparency. Rather than simply presenting selected journal articles without explanation, PRISMA requires researchers to document the entire review process. This allows readers, supervisors, and examiners to understand exactly how evidence was collected and why certain studies were included or excluded.
The PRISMA framework for literature review writing is particularly valuable because it reduces researcher bias. Without a structured process, students may unintentionally select only studies that support their argument while ignoring contradictory evidence. PRISMA encourages a systematic and balanced approach.
Although PRISMA originated within healthcare and clinical research, it is now widely used across disciplines. Students in education, nursing, business management, public health, sociology, and psychology frequently apply PRISMA guidelines when conducting systematic or semi-systematic reviews.
For example, a master’s student investigating the impact of remote learning on student performance might use PRISMA to systematically search educational databases, screen relevant studies, and present a transparent review methodology. Similarly, a business student researching employee wellbeing in hybrid workplaces could use PRISMA to justify how sources were selected.
As discussed in our guide to literature review example writing techniques, one of the biggest weaknesses in student research is poor methodological transparency. PRISMA addresses this issue directly.
What Are the PRISMA Guidelines Used For?
Many students ask: What are the PRISMA guidelines used for? The answer is broader than most people realise.
PRISMA guidelines are primarily used to improve the reporting quality of systematic literature reviews and meta-analyses. They help researchers present their review methods in a structured and transparent way. Instead of vaguely describing database searches or article selection, researchers following PRISMA provide detailed information about search terms, databases, eligibility criteria, and screening procedures.
This has several advantages.
First, PRISMA improves research credibility. Supervisors and examiners can clearly evaluate whether the review process was rigorous and unbiased.
Second, PRISMA enhances reproducibility. Other researchers should theoretically be able to repeat your search strategy and obtain similar results.
Third, PRISMA improves readability. A structured review process makes complex research easier for readers to follow.
Finally, PRISMA helps researchers avoid common literature review mistakes such as selective sourcing, inconsistent screening, or unclear inclusion criteria.
Many UK universities now encourage or require PRISMA-based reporting for systematic reviews. Institutions such as the University of Oxford, King’s College London, and the University of Manchester frequently reference PRISMA in research methods guidance for postgraduate students.
The Quality Assurance Agency (QAA) also places strong emphasis on research integrity, critical evaluation, and methodological transparency within higher education standards. PRISMA aligns closely with these academic expectations.
The Four Steps of a PRISMA Review
One of the most common questions students ask is: What are the four steps of a PRISMA?
The PRISMA process is generally divided into four key stages:
Identification
During the identification stage, researchers search academic databases to locate potentially relevant studies. This involves selecting databases, creating search strings, and recording the number of results obtained.
For instance, a student researching social media addiction among university students may search databases such as Scopus, Web of Science, PubMed, and Google Scholar using keywords like “social media addiction”, “student wellbeing”, and “higher education”.
The goal is to gather a comprehensive pool of studies without prematurely excluding potentially useful evidence.
Screening
The screening stage involves removing duplicate studies and reviewing titles and abstracts to determine relevance.
At this point, irrelevant articles are excluded based on predefined criteria. For example, studies focused solely on school-aged children might be removed from a university-focused review.
A clear screening process is essential because examiners often assess whether exclusion decisions were justified and unbiased.
Eligibility
The eligibility stage requires full-text assessment of remaining articles.
Students carefully read each study to determine whether it meets inclusion criteria. Articles may be excluded because they lack empirical data, fall outside the publication period, use unsuitable methodologies, or fail to address the research question directly.
This stage often takes longer than expected because critical evaluation becomes more detailed.
Inclusion
The final stage includes the studies selected for the literature review or meta-analysis.
Researchers synthesise findings, identify themes, compare methodologies, and evaluate evidence quality.
This is where the literature review itself is written, supported by transparent documentation of how studies were chosen.
Understanding the PRISMA 2020 Guidelines
The updated PRISMA 2020 guidelines introduced several important improvements to reflect changes in modern research practices.
Earlier PRISMA versions focused heavily on traditional systematic reviews. However, research methods have evolved considerably, especially with the growth of digital databases, automation tools, and interdisciplinary research.
The PRISMA 2020 checklist expanded reporting requirements and encouraged greater detail regarding search strategies, data collection, and study selection.
Some major updates include:
- Improved guidance for reporting database searches
- Enhanced transparency regarding excluded studies
- Updated PRISMA flow diagram formats
- Greater emphasis on automation tools and screening software
- Better reporting standards for abstracts
The PRISMA 2020 abstract checklist is particularly important because many journals now require structured abstracts that summarise review methods clearly.
Students often overlook the abstract section when conducting literature reviews, but concise and transparent reporting significantly strengthens academic credibility.
How to Use PRISMA for Literature Review Writing
Understanding theory is one thing. Applying PRISMA effectively is another challenge altogether.
When learning how to use PRISMA for literature review writing, it helps to think of PRISMA as both a reporting framework and a research management system.
You should begin by developing a focused research question. Broad topics make systematic searching extremely difficult. For example, “technology in education” is too wide, while “the impact of AI-assisted learning tools on postgraduate student engagement in UK universities” is more manageable.
Next, identify suitable academic databases. Depending on your discipline, you may use Scopus, PubMed, JSTOR, PsycINFO, ERIC, or Web of Science.
Your search strategy must then be carefully documented. This includes recording keywords, Boolean operators, filters, and publication years.
For example:
“artificial intelligence” AND “higher education” AND “student engagement”
You should also define inclusion and exclusion criteria before screening studies. This is a critical PRISMA principle because it reduces selection bias.
Typical inclusion criteria may involve:
- Peer-reviewed journal articles
- English-language studies
- Research published between 2018–2026
- Empirical studies involving university students
Once studies are screened and selected, create your PRISMA flow diagram showing the number of records identified, screened, excluded, and included.
Finally, synthesise findings thematically or critically rather than merely summarising individual articles.
As explained in our guide to dissertation writing samples, strong literature reviews compare studies, identify gaps, evaluate methodologies, and build coherent academic arguments.
PRISMA Checklist Explained with Practical Examples
The PRISMA checklist is one of the most important tools within the framework. It ensures that researchers report all essential review components systematically.
The checklist covers areas such as:
- Title and abstract reporting
- Introduction and objectives
- Search strategy documentation
- Study selection methods
- Data extraction
- Risk of bias assessment
- Results synthesis
- Discussion and limitations
For example, imagine a PhD student investigating mental health interventions for university students in the UK.
Without PRISMA, the student might simply mention searching “several databases”. However, PRISMA requires far more detail:
- Which databases were searched
- Which keywords were used
- When searches were conducted
- How duplicates were removed
- Why certain studies were excluded
This level of detail strengthens academic trustworthiness significantly.
Many students also use downloadable PRISMA guidelines PDF documents and PRISMA 2020 guidelines PDF resources when structuring methodology chapters.
The Importance of the PRISMA Flow Diagram
The PRISMA flow diagram is one of the most recognisable features of systematic reviews.
It visually summarises the review process from identification to inclusion. Examiners appreciate flow diagrams because they simplify complex screening procedures and improve transparency.
A standard PRISMA flow diagram typically includes:
- Number of records identified
- Number of duplicates removed
- Records screened
- Full-text articles assessed
- Studies excluded with reasons
- Final included studies
For instance, a nursing student may identify 2,000 studies initially, remove 600 duplicates, screen 1,400 titles and abstracts, assess 120 full texts, and ultimately include 35 studies.
Presenting this information visually improves readability and demonstrates methodological rigour.
Common Challenges Students Face with PRISMA
Although PRISMA is highly valuable, students frequently encounter practical difficulties when applying it.
One major issue is overly broad research questions. Broad topics generate thousands of search results, making screening unmanageable.
Another challenge involves inconsistent inclusion criteria. Some students modify criteria midway through the review process, which weakens methodological integrity.
Time management is another common problem. Systematic reviews require substantial organisation and documentation. Students often underestimate how long screening and data extraction will take.
Many students also struggle with database searching techniques. Using ineffective keywords or poor Boolean logic can either produce too many irrelevant studies or miss important research entirely.
Finally, some students treat PRISMA as a simple checklist rather than a methodological framework. Merely adding a flow diagram without conducting systematic searching properly does not meet academic standards.
Practical Tips for Using PRISMA Successfully
To use PRISMA effectively, organisation is absolutely essential.
Create a spreadsheet to track database searches, inclusion decisions, excluded studies, and key article findings. Reference management software such as Zotero, EndNote, or Mendeley can also simplify duplicate removal and citation management.
You should pilot your search strategy early to ensure keywords produce relevant results. Small adjustments to search terms can dramatically improve evidence quality.
It is also wise to discuss your PRISMA methodology with your supervisor before beginning full screening. Early feedback can prevent major structural problems later.
Remember that PRISMA is designed to improve research quality rather than complicate your dissertation. Once students understand the framework properly, it often makes literature review writing more organised and manageable.
Why PRISMA Matters in UK Higher Education
The growing importance of evidence-based research across UK higher education means PRISMA is likely to become even more significant in future dissertations and research projects.
Research Excellence Framework (REF) expectations increasingly emphasise methodological quality, transparency, and impact. As universities continue prioritising research integrity, students who understand systematic review methods gain a valuable academic advantage.
PRISMA also supports transferable research skills. Students who learn systematic searching, evidence synthesis, and transparent reporting become stronger researchers overall.
These skills are particularly valuable for postgraduate study, journal publication, and academic careers.
Conclusion
Using PRISMA guidelines for literature reviews can transform the quality, structure, and credibility of your research. Rather than approaching literature reviews as loosely organised summaries, PRISMA encourages systematic thinking, transparent reporting, and rigorous evidence evaluation.
By understanding the four steps of PRISMA, applying the PRISMA 2020 checklist correctly, and using tools such as the PRISMA flow diagram, you can produce literature reviews that meet modern academic standards expected by UK universities.
Most importantly, PRISMA helps you become a more confident and methodical researcher. Whether you are writing a master’s dissertation, preparing a PhD thesis, or conducting a systematic review for publication, these skills will continue benefiting your academic journey long after graduation.
