In the formulation of the clinical question of traditional Chinese medicine clinical practice guidelines, even if the intervention elements (intervention or control) have an appropriate scope, guideline developers are still faced with a variety of interventions. By analyzing the difficulty and necessity of priority selection of intervention interventions, we propose the approach of extending expert evidence to the process of priority selection of intervention interventions, and further provide the methodology of expert evidence data collection table design, application, data presentation and expert decision-making method to provide references and guidance for guideline developers.
Clinical practice guidelines will be incorporated in different evidence sources and evidence types, the research and exploration of multiple sources of evidence at China and foreign, this paper advocates the construction of both characteristics of multi-source evidence of traditional Chinese medicine, by combing 70 guide manuals, analyze the necessity and advantages of multi-source evidence construction, and further from the multi-source evidence source and evidence logic theory interpretation and application, in order to provide methodological references for the formulation of evidence-based clinical practice guidelines of traditional Chinese medicine.
In the process of formulation, traditional Chinese medicine clinical practice guidelines are often faced with the dilemma of lack of evidence. Guidelines development groups tend to make final decisions based on expert experience or expert opinion, but the limitations of cognitive bias reduce the credibility and transparency of the guidelines. By clarifying the difference between the expert experience and expert opinion and expert evidence, the expert evidence of traditional Chinese medicine discipline advantages and necessity, providing the recommendation form link using expert evidence methodology design and implementation details, retaining the empirical characteristics of traditional Chinese medicine and improving the lack of evidence, has certain practical application value.
