There is considerable actual and potential waste in research. The aim of this article is to describe how using an evidence-based research approach before conducting a study helps to ensure that the new study truly adds value.
Evidence-based research is the use of prior research in a systematic and transparent way to inform a new study so that it is answering questions that matter in a valid, efficient, and accessible manner. In this second article of the evidence-based research series, we describe how to apply an evidence-based research approach before starting a new study.
Before a new study is performed, researchers need to provide a solid justification for it using the available scientific knowledge as well as the perspectives of end users. The key method for both is to conduct a systematic review of earlier relevant studies.
Describing the ideal process illuminates the challenges and opportunities offered through the suggested evidence-based research approach. A systematic and transparent approach is needed to provide justification for and to optimally design a relevant and necessary new study.
研究中存在大量实际和潜在的浪费。本文的目的是描述在进行研究之前如何使用基于证据的研究方法，以确保新的研究真正具有价值。
基于证据的研究是指系统透明地利用先前的研究来为新的研究提供信息，以使其以有效、高效和可及的方式回答重要的问题。在证据基础研究系列的第二篇文章中，我们描述了在进行新研究之前如何应用基于证据的研究方法。
在进行新的研究之前，研究人员需要使用现有科学知识以及最终用户的观点，为研究提供合理的依据。关键方法是对以前相关研究进行系统综述。
描述理想的过程可以阐明通过建议的基于证据的研究方法提供的挑战和机遇。需要系统透明的方法来为相关和必要的新研究提供依据，并进行最佳设计。
