Evidence-based practice is a process to which clinical professionals adhere when making decisions concerning the assessment or treatment of a given condition. Within the field of speech-language pathology, it is increasingly advocated as best practice. As our profession seeks to transform itself from one that is primarily craft-based to one that relies on evidence-based processes, it must develop and implement a series of structures that will foster this transformation. This article describes three specific structures that are increasingly available within the field of speech-language pathology in the United States to guide transformation of the profession: systematic reviews and meta-analyses, treatment studies, and clearinghouses. Without these structural supports, it is unlikely that evidence-based practice can be scaled up in a way that has positive impacts on practice.
循证实践是临床专业人员在针对特定病症的评估或治疗做出决策时所遵循的过程。在言语病理学领域，它越来越被倡导为最佳实践。随着我们这个行业力求从主要基于技艺的行业转变为依赖循证过程的行业，它必须开发并实施一系列有助于促成这种转变的架构。本文介绍了美国言语病理学领域越来越多可用于指导该行业转型的三种具体架构：系统评价和荟萃分析、治疗研究及信息交换中心。没有这些结构性支持，循证实践就不太可能以对实践产生积极影响的方式得到推广。
