Scoping reviews and evidence map methodologies are increasingly being used by researchers. The objective of this article is to examine how scoping reviews can reduce research waste.
This article summarizes the key issues facing the research community regarding research waste and how scoping reviews can make an important contribution to the reduction of research waste in both primary and secondary research.
The problem of research waste is an enduring challenge for global health, leading to a waste of human and financial resources and producing research outputs that do not provide answers to the most pressing research questions. Research waste occurs within primary research but also in secondary research such as evidence syntheses. The focus of scoping reviews on characterizing the nature of existing evidence on a topic and including all types of evidence, potentially reduces research waste in five ways: (1) identifying key research gaps on a topic, (2) determining appropriate outcome measures, (3) mapping existing methodological approaches, (4) developing a consistent understanding of terms and concepts used in existing evidence, and (5) ensuring scoping reviews do not exacerbate the issue of research waste.
To ensure that scoping reviews do not themselves end up contributing to research waste, it is important to register the scoping review and to ensure that international reporting standards and methodological guidance are followed.
研究人员越来越多地使用范围综述和证据图谱方法。本文的目的是探讨范围综述如何减少研究浪费。
本文总结了研究界在研究浪费方面面临的关键问题，以及范围综述如何能在初级和次级研究中为减少研究浪费做出重要贡献。
研究浪费问题是全球健康面临的持久挑战，导致人力和财力资源的浪费，并产生无法回答最紧迫研究问题的研究成果。研究浪费不仅发生在初级研究中，也发生在诸如证据综合等次级研究中。范围综述关注于描述某一主题现有证据的性质并纳入所有类型的证据，这可能从五个方面减少研究浪费：（1）识别某一主题的关键研究空白；（2）确定合适的结局指标；（3）梳理现有的方法学途径；（4）对现有证据中使用的术语和概念形成一致的理解；（5）确保范围综述不会加剧研究浪费问题。
为确保范围综述本身不会最终导致研究浪费，对范围综述进行注册并确保遵循国际报告标准和方法学指南非常重要。
