传统的循证医学概念在很大程度上依赖于随机对照试验。虽然扩大证据定义的倡议已经提出，但它们一般没有将证据标准正式和定量地与决定采取或拒绝干预措施所涉及的利益和成本联系起来。决策分析提供了一个框架，用于结合信息，以这种方式为采用决策提供信息。信息价值分析是一种相关的方法，有助于确定是否值得收集更多的信息以及最有帮助的研究类型。
Traditional conceptualizations of evidence-based medicine rely heavily on randomized controlled trials. Although initiatives to broaden definitions of evidence have been advanced, they generally have not tied evidentiary criteria formally and quantitatively to the benefits and costs involved in a decision to adopt or reject an intervention. Decision analysis provides a framework for combining information to inform the adoption decision in this manner. Value-of-information analysis, a related methodology, helps to determine whether it is worthwhile to collect additional information as well as the type of research that would be most helpful.
