The Importance of Background Information in Evidence Synthesis

The Importance of Background Information in Evidence Synthesis

Introduction:
When conducting evidence synthesis, it is crucial to have a strong understanding of the background information related to the topic under review. This article will explore the significance of background information in evidence synthesis, how it can be modified or extended following a scoping review, and the benefits of conducting preliminary searches for previous reviews. Additionally, we will discuss the use of dataset builders and filters to analyze the evolution of available documents over time.

Importance of Background Information in Evidence Synthesis:
Background information is essential in evidence synthesis as it provides context and a foundation for understanding the topic. It helps reviewers identify knowledge gaps, determine the scope of the review, and establish the rationale and objectives of the study. Without a comprehensive understanding of the background information, reviewers may overlook important aspects or fail to address relevant research questions.

Modifying and Extending Background Information:
While the "Introduction" section of a protocol usually covers the background information, it is common for reviewers to find the need for modification or extension after conducting a scoping review. The scoping review introduces the results of the review project and may reveal gaps in the existing background information. Reviewers should ensure that the modified or extended background information aligns with the concept of the topic under review and includes any new insights gained from the scoping review.

Preliminary Searches for Previous Reviews:
Conducting preliminary searches for previous scoping reviews and systematic reviews on the same topic is crucial. This step helps reviewers identify existing evidence and prevents duplication of efforts. By assessing previous reviews, reviewers can build upon the existing knowledge and identify areas that require further investigation. It also allows them to evaluate the methodology and outcomes of previous studies, which can inform the design and objectives of their own review.

Utilizing Dataset Builders and Filters:
In the process of evidence synthesis, dataset builders and filters play a vital role in organizing and analyzing the available information. Dataset builders, such as Constellate dell'editore Ithaka, allow researchers to extract relevant content from their search and visualize it chronologically. This enables them to track the evolution of documents available in databases and repositories based on the adopted filters. By using filters, reviewers can refine their search results and focus on specific aspects, such as publication date, document type, or author, to gain a better understanding of the available evidence.

Actionable Advice:

1. Invest time in thoroughly understanding the background information related to your topic before embarking on evidence synthesis. This will provide a solid foundation for your review and help identify knowledge gaps.

2. After conducting a scoping review, critically evaluate and modify the background information provided in your protocol. Ensure that it aligns with the concept of your review and incorporates any new insights gained.

3. Conduct preliminary searches for previous scoping reviews and systematic reviews on the same topic. This will help you build upon existing knowledge, avoid duplication, and inform the design and objectives of your own review.

Conclusion:
Background information plays a crucial role in evidence synthesis, providing context and guiding the review process. Reviewers should be prepared to modify and extend the background information following a scoping review to ensure its relevance and comprehensiveness. Preliminary searches for previous reviews are essential to avoid duplication and leverage existing evidence. Utilizing dataset builders and filters can enhance the organization and analysis of available information. By following these practices, reviewers can conduct evidence synthesis effectively and contribute to the advancement of knowledge in their respective fields.
