Navigating evidence: a concise guide to types of literature review commonly used in healthcare research.

Abstract

Background: Literature reviews evaluate the evidence currently available concerning a particular phenomenon of interest. They are essential tools that offer healthcare professionals insights into existing knowledge, identify gaps and guide future studies. There are different types of literature review, each of which has unique purposes, methodologies, strengths and limitations, and researchers must select the type most appropriate to their needs.

Aim: To discuss the main features of common types of literature review, clarify their characteristics and guide healthcare professionals and researchers in making informed decisions.

Discussion: It can be challenging to choose a type of literature review as it must align with the focus of your research. The type you choose will influence the depth of your analysis and the applicability of your findings to clinical practice. It is therefore crucial to understand the different types and their applications, so you can select the type most appropriate to your research, ensure it effectively addresses your research questions and contributes insights.

Conclusion: Choosing the right type of literature review is crucial for effectively addressing research questions and advancing knowledge in healthcare. Understanding the distinct purposes and methodologies of different types of review will help you to make an informed choice that enhances the relevance and impact of your research, leading to stronger evidence and better outcomes.

Implications for practice: Healthcare professionals will be able to ensure their research is methodologically sound and relevant in practice. This will ultimately lead to better-informed decisions and improved outcomes for patients.
