Narrative Synthesis in Systematic Reviews

Learning Objectives

By the end of this chapter, you will be able to:

  • Understand the role of narrative synthesis in systematic reviews.
  • Apply methods for conducting a narrative synthesis effectively.
  • Integrate findings into a coherent narrative to support your research conclusions.

Introduction

Narrative synthesis is a vital component of systematic reviews, especially when quantitative synthesis (meta-analysis) is not feasible. It involves summarizing and explaining the findings of multiple studies in a systematic and transparent manner.

This chapter will guide you through the process of conducting a narrative synthesis, from organizing data to presenting a coherent narrative.

Steps to Conduct a Narrative Synthesis

Begin by organizing your studies into meaningful groups based on key characteristics:

  • By Intervention Type: Group studies with similar interventions.
  • By Population: Consider age, gender, or other demographic factors.
  • By Outcome: Focus on studies with similar outcomes.

Refer to your systematic review protocol for guidance on grouping criteria.

Create a framework to guide the synthesis process:

  • Identify Key Concepts: Determine the main themes and variables.
  • Establish Relationships: Explore how these concepts interrelate.
  • Define Contexts: Consider the settings and conditions of the studies.

Use visual aids like concept maps to illustrate your framework.

Combine findings from different studies to create a cohesive narrative:

  • Identify Patterns: Look for recurring themes and results across studies.
  • Explain Variations: Discuss differences and contradictions in findings.
  • Highlight Gaps: Note areas where evidence is lacking or inconsistent.

Ensure transparency by clearly describing your synthesis process.

Effectively present your narrative synthesis:

  • Structure the Narrative: Use headings and subheadings for clarity.
  • Use Visual Aids: Incorporate tables, graphs, and charts to illustrate key points.
  • Summarize Clearly: Provide concise summaries of each section.
  • Link to Evidence: Reference studies to support your narrative.

Consider the needs of your audience when crafting your narrative.

Best Practices

Ensure Clarity and Coherence
  • Consistency: Maintain a consistent style and format throughout the narrative.
  • Transparency: Clearly document all synthesis decisions and processes.
  • Logical Flow: Ensure the narrative follows a logical progression.
Enhance Credibility
  • Use Robust Methods: Employ systematic approaches to synthesis.
  • Involve Multiple Reviewers: Reduce bias through collaborative synthesis.
  • Peer Review: Seek feedback from colleagues to refine the narrative.
Engage Your Audience
  • Use Clear Language: Avoid jargon and explain complex concepts simply.
  • Visual Appeal: Use design elements to make the narrative engaging.
  • Interactive Elements: Consider digital tools for interactive presentations.

Conclusion

Narrative synthesis allows for a comprehensive understanding of complex data when a meta-analysis is not feasible. By systematically organizing and presenting findings, you can provide valuable insights that enhance the understanding of the research topic.
