A systematic literature review form: Your comprehensive guide
Understanding systematic literature reviews
A systematic literature review is a structured approach to synthesizing research evidence on a specific topic. Unlike traditional literature reviews, which can be subjective and selective in the choice of literature, systematic reviews follow a rigorous methodology that aims to minimize bias and enhance reliability.
The primary purpose of a systematic literature review is to provide comprehensive insights into existing research to inform clinical practice, policy-making, or further studies. By synthesizing diverse studies, these reviews help identify gaps in research and summarize what is known about a topic.
Systematic reviews offer a more objective and replicable methodology.
They are crucial for evidence-based practice, especially in fields like healthcare.
Systematic reviews can uncover patterns and trends not immediately obvious from individual studies.
Step-by-step guide to conducting a systematic literature review
The process of conducting a systematic literature review can be daunting without a clear plan. Here’s a detailed step-by-step guide to navigate this complex task.
Step 1: Define your research questions
Effective research questions serve as the foundation of your review. They should be clear, focused, and researchable, guiding your entire systematic review process.
Formulate questions based on gaps identified in current research.
Ensure questions are specific to control the scope of your review.
Use the PICO format (Population, Intervention, Comparison, Outcome) for clinical questions.
Step 2: Develop your protocol
Creating a detailed protocol is crucial for guiding your review process. This document outlines your methodology, including your research questions, search strategies, and inclusion/exclusion criteria.
Frameworks like PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and Cochrane provide templates and guidelines to enhance your protocol's comprehensiveness and transparency.
Include a rationale for the review and your predefined criteria.
Establish timelines and responsibilities for team members if applicable.
Document potential conflicts of interest.
Step 3: Select databases and sources
Choosing the right databases and sources is pivotal in gathering comprehensive literature for your review. Key databases like PubMed, Scopus, and Web of Science are essential for accessing peer-reviewed articles across various disciplines.
Additionally, consider including grey literature sources such as theses, government reports, and conference proceedings, which can provide valuable data often overlooked in traditional databases.
Identify core databases relevant to your field.
Consider interdisciplinary databases for broader research.
Compile a list of grey literature sources to enrich data diversity.
Step 4: Design your search strategy
A well-thought-out search strategy is critical to retrieving relevant literature. Begin by defining effective search terms related to your research questions.
Utilizing Boolean operators (AND, OR, NOT) and filters will help refine your search results and render them more manageable. For instance, using ‘AND’ can narrow searches, whereas ‘OR’ widens them.
Draft keywords and synonyms for comprehensive searches.
Adjust search terms based on preliminary results.
Document search strategies for transparency.
Step 5: Execute the literature search
With your strategy in place, execute the literature search across chosen databases. Record the date and query string used for each search to track your methods and ensure replicability.
Merging results from different databases may require special software or tools to avoid duplications and ensure a comprehensive overview.
Export results to reference management software for organization.
Remove duplicates systematically.
Keep a log of your search history for reproducibility.
Step 6: Apply inclusion and exclusion criteria
A vital component of systematic reviews is rigorously applying inclusion and exclusion criteria to the collected literature. These criteria help ensure that only the most relevant studies are included in your analysis.
Define criteria based on population, intervention, study design, and outcomes.
Include a rationale for each criterion to enhance clarity.
Be prepared to reassess and adjust criteria based on emerging findings.
Step 7: Conduct a quality assessment
Quality assessment of the studies included in your review is crucial to determine their reliability and applicability. Various tools, such as the Cochrane Risk of Bias tool, can help evaluate the quality of evidence.
It's essential to recognize the potential for bias within studies and its impact on your systematic review. Establish guidelines for how quality assessments will influence your synthesis.
Select appropriate quality assessment tools specific to your research area.
Create a checklist for evaluating each study’s quality.
Be transparent about the limitations identified during assessments.
Step 8: Data extraction and synthesis
Data extraction involves meticulously pulling together qualitative and quantitative information from studies deemed suitable for your review. Establish a standardized form for consistent data entry to streamline this process.
Synthesis can take various forms, from narrative synthesis, which summarizes findings descriptively, to quantitative synthesis or meta-analysis, depending on the nature of your data.
Utilize data extraction templates for systematic capturing of relevant data.
Document any challenges faced in extracting data.
Choose synthesis methods aligning with the study designs included.
Step 9: Write your review
When crafting your systematic literature review, maintain a logical flow and clarity across sections. Standard components of a systematic review include an introduction, methods, results, discussion, and conclusion.
Use clear and concise language to communicate your findings effectively. Ensure that your writing remains accessible, maintaining engagement without sacrificing precision.
Structure your review to enhance readability: clear headings, subheadings, and logical progression.
Cite sources appropriately especially for critical evaluations.
Proofread extensively to eliminate errors.
Step 10: Report your findings
Reporting your systematic review findings requires adherence to established standards like PRISMA to ensure transparency and completeness. This ultimately enables your review to contribute efficiently to the body of knowledge in your field.
Consider effective dissemination strategies to maximize the impact of your findings. This includes publishing in peer-reviewed journals, presenting at conferences, or sharing in professional networks.
Follow PRISMA guidelines for transparent reporting.
Engage with stakeholders who can benefit from your findings.
Utilize digital platforms for wider dissemination.

Understanding the role of grey literature
Grey literature encompasses information not publicly available through conventional channels, such as reports, theses, and conference abstracts. Including grey literature in systematic reviews enriches the body of evidence and can highlight findings not represented in peer-reviewed articles.
Effective strategies for identifying grey literature include targeted searches in government databases, contacting researchers directly, or utilizing resources such as OpenGrey or the Grey Literature Report.
Incorporate searches specifically targeting thesis and dissertation databases.
Connect with researchers to access unpublished data.
Examine industry reports for contemporary insights.
Common pitfalls and how to avoid them
Conducting a systematic literature review presents unique challenges. Common pitfalls include vague research questions, inadequate search strategies, and overlooking quality assessments.
To mitigate these risks, maintaining clarity during the entire process is key. Detailed documentation throughout your review will also support transparency and make it easier to build upon future research.
