Understanding Scoping Reviews: A Comprehensive Overview

Understanding Scoping Reviews: A Comprehensive Overview

The evolution of scoping reviews is a fascinating journey in the realm of evidence synthesis. Originally termed "mapping reviews" or "scoping studies," the framework for conducting these reviews was introduced by Arksey and O’Malley in 2005. Over the years, the methodology has been refined and expanded upon by various scholars, including Levac and colleagues in 2010, as well as working groups associated with the Joanna Briggs Institute (JBI) and the JBI Collaboration (JBIC). The term "systematic scoping review," initially used by Peters and others in 2015 and 2017, has since been simplified to "scoping reviews," acknowledging that systematic approaches are essential in all forms of knowledge synthesis. This evolution culminated in the development of the PRISMA-ScR statement, an extension of the PRISMA guidelines specifically tailored for scoping reviews.

The Purpose and Advantages of Scoping Reviews

The primary aim of a scoping review is to map the key concepts underpinning a particular field of research. This involves clarifying definitions and conceptual boundaries, summarizing existing literature, and identifying gaps in knowledge. Scoping reviews serve several critical purposes:

1. Mapping the Evidence: They provide a comprehensive overview of the breadth and extent of literature on a specific topic, helping researchers and practitioners understand the landscape of available evidence.

2. Identifying Knowledge Gaps: By analyzing existing research, scoping reviews highlight areas that lack sufficient evidence, which can inform future studies and initiatives.

3. Clarifying Concepts: Scoping reviews delve into the definitions and characteristics of key concepts within the literature, which is crucial when the research question is not sharply defined.

4. Informing Future Research: The insights gained from scoping reviews guide researchers in formulating more precise questions and hypotheses for subsequent systematic reviews.

5. Examining Research Conduct: They provide an overview of how research is conducted within a particular field, offering insights into methodologies and practices employed by researchers.

The flexibility of scoping reviews makes them particularly valuable when researchers are interested in broader concepts rather than specific clinical questions. They enable authors to explore various characteristics and concepts within the evidence without being confined to a strict methodological appraisal of quality.

Actionable Advice for Conducting Scoping Reviews

For researchers looking to undertake scoping reviews, here are three actionable pieces of advice:

1. Clearly Define Your Aim: Before embarking on a scoping review, ensure that you have a well-defined aim. Consider what you want to achieve, whether it is mapping evidence, identifying knowledge gaps, or clarifying concepts. A clear aim will guide your review process and help you articulate your rationale.

2. Develop a Comprehensive Protocol: Documenting your methodology in a detailed protocol is essential. This protocol should outline your search strategy, inclusion/exclusion criteria, and methods for data extraction and synthesis. A well-structured protocol not only enhances transparency but also facilitates consistency throughout the review process.

3. Engage Stakeholders Early: Involving stakeholders, such as practitioners, policymakers, and other researchers, early in the scoping review process can provide valuable insights and ensure that the review addresses relevant questions. Their input can also enhance the practical implications of your findings.

Conclusion

Scoping reviews play an integral role in the landscape of evidence synthesis by providing a broad overview of existing literature and identifying gaps in knowledge. As the number of scoping reviews continues to rise, understanding their methodology and purpose becomes increasingly important. By clearly defining aims, creating comprehensive protocols, and engaging stakeholders, researchers can effectively leverage scoping reviews to inform future research and practice. This systematic approach not only enriches the field of inquiry but also contributes to the advancement of knowledge and evidence-based practice in various disciplines.
