Exploring the Rationale and Process of Scoping Reviews: A Comprehensive Guide

Introduction

Scoping reviews are an essential methodology in evidence synthesis that aims to explore a specific research area comprehensively. Unlike systematic reviews, scoping reviews are more exploratory in nature, and their purpose is not to cover all existing knowledge on the topic. Instead, they provide a broad overview of the available evidence and identify gaps for further research. In this article, we will delve into the rationale, process, and significance of conducting scoping reviews.

Rationale for Conducting Scoping Reviews

To understand the context and importance of scoping reviews, it is crucial to consider whether previous scoping reviews, systematic reviews, research syntheses, or primary research papers exist on the topic. Conducting a preliminary search for existing evidence helps to determine if there is a need for a scoping review. This preliminary search should include the date of the search(es), the journals and databases searched, and the search platforms utilized.

If existing scoping reviews or systematic reviews are available on the topic, it is essential to articulate how the proposed review will differ from those already conducted. This justification is crucial to ensure that the scoping review will contribute new knowledge or insights to the existing evidence syntheses. By identifying the gaps in current knowledge, scoping reviews pave the way for future research and inform evidence-based practice.

Elements of a Comprehensive Introduction

When writing the introduction for a scoping review, it is necessary to provide sufficient detail about the population, concept, and context under review. This information sets the stage for the reader and establishes the rationale for each element. By clearly defining the scope and objectives of the review, the introduction sets expectations and guides the subsequent sections of the scoping review.

The Process of Conducting a Scoping Review

Once the rationale and objectives are established, the process of conducting a scoping review can begin. This typically involves several stages, including identifying the research question, selecting appropriate inclusion and exclusion criteria, searching for relevant literature, extracting data from the selected studies, and synthesizing the findings.

During the search for relevant literature, it is important to cast a wide net and explore a variety of sources, including academic journals, databases, grey literature, and expert opinions. This comprehensive approach ensures that all relevant evidence is considered and minimizes the risk of bias. The inclusion and exclusion criteria should align with the overarching objectives of the review and help filter the literature to include only the most relevant studies.

Key Takeaways and Actionable Advice

1. Conduct a preliminary search: Before embarking on a scoping review, it is crucial to conduct a preliminary search to determine if there is a need for such a review. This search should include existing scoping reviews, systematic reviews, research syntheses, and primary research papers on the topic.

2. Articulate the uniqueness of the proposed review: If previous reviews exist, it is essential to justify how the proposed scoping review will differ from those already conducted. By identifying the gaps in the existing evidence, the scoping review can contribute new knowledge or insights to the field.

3. Cast a wide net during the literature search: To ensure the comprehensiveness of the scoping review, it is important to search for relevant literature across various sources. This includes academic journals, databases, grey literature, and expert opinions.

Conclusion

Scoping reviews play a vital role in evidence synthesis by providing a comprehensive exploration of a specific research area. By identifying existing evidence gaps and informing future research directions, scoping reviews contribute to the advancement of knowledge and evidence-based practice. By following a systematic process and incorporating the actionable advice provided, researchers can conduct rigorous and impactful scoping reviews that benefit the scientific community.
