Consensus research methods are used in health services research to generate evidence through systematic means of measuring collective agreement and developing consensus from experts of a subject matter. Delphi technique is the most commonly reported consensus research method and is a structured, multistage interaction method to determine consensus using repetitive administration of anonymous questionnaires across two or three rounds. The Delphi technique is increasingly being used in pharmacy practice research. Despite its wide use in the development of statements of policies, guidelines, and performance indicators, there is lack of standardized guidelines and criteria to support the Delphi technique study design, conduct, and reporting, leading to inconsistent approaches and methodological difficulties among researchers. In this themed article, we provide the reader with a collation of best practices and highlight key methodological issues and areas of uncertainty of the Delphi method, especially as it pertains to pharmacy practice research.

共识研究方法用于卫生服务研究，通过衡量集体协议的系统方法和与主题专家达成共识来生成证据。Delphi 技术是最常报道的共识研究方法，是一种结构化、多阶段的交互方法，通过重复管理两轮或三轮匿名问卷来确定共识。Delphi 技术越来越多地用于药学实践研究。尽管它广泛用于制定政策、指南和绩效指标的声明，但缺乏支持德尔菲技术研究设计、实施和报告的标准化指南和标准，导致研究人员之间的方法不一致和方法论困难。在这篇主题文章中，
