The formation of expert consensus statement is an indispensable part in the process of developing clinical practice guidelines. The Guidelines International Network believes that experts make group decisions for different stages and issues,and the process of gathering expert opinions is the process of reaching the consensus. GRADE system also requires that recommendations should be formed based on expert consensus in consideration of the risk and bias,patients' preferences and values,resources and other factors. At present,the main method for reaching consensus is the formal consensus method. According to the published clinical guidelines,most of them failed to report the specific methods and process of reaching expert consensus. Therefore,it is impossible to obtain an objective evaluation. This phenomenon is more common in the field of clinical practice guidelines of traditional Chinese medicine( TCM). There are two main reasons for this phenomenon. For one thing,the developers of the guidelines neglect the importance of transparency and objectivity in the implementation of expert consensus. For another,they know little about the methods and technical specifications for the formation of expert consensus. To solve them,based on the internationally recognized consensus-building methods,as well as the specific stages in the process of developing clinical practice guidelines of traditional Chinese medicine,it is of great significance to put forward the technical norms for TCM researchers to develop the expert consensus. This guide will provide detailed guidance for forming the expert consensus for TCM clinical practice guideline. This guideline has been approved and published by the Chinese Association of Traditional Chinese Medicine( No. T/CACM 1049-2017).
