Application Of Delphi Method To Explore The Common TCM Syndrome Types And Distribution Of Classification Indicators Of Diabetic Gastroparesi

Purpose : The Delphi method was used to conduct an expert investigation on the classification of diabetic gastroparesis and the indicators of each syndrome,and to preliminarly establish the common syndrome classification and indicators of diabetic gastroparesis,provide reference and basis for clinical differentiation and treatment,and to provide reference for future standardized research on the diagnosis of diabetic gastroparesis.Material and method:Through literature search and according to the inclusion criteria,the qualified literatures were screened out.After reading,a TCM syndrome questionnaire of diabetic gastroparesis was summarized and constructed.An expert group was established and Delphi method was used to conduct expert opinion survey of diabetic gastroparesis,statistical analysis and sensitivity test,and test stability and repeatability.The questionnaire of this study first investigated the TCM syndromes of diabetic gastroparesis,and experts made judgments on TCM syndrome differentiation of diabetic gastroparesis based on clinical experience,and gave personal modification and supplementary opinions.The expert questionnaire of the first round was collected,and the data were sorted and analyzed.The TCM syndrome differentiation and syndrome types of diabetic gastroparesis were evaluated,modified and improved by the final coefficient and expert opinions,and the expert questionnaire of the second round was formed,and corresponding data were obtained in accordance with the method of the first round.Finally,summarize and conclude the common TCM syndrome types and classification indexes of diabetic gastroparesis.Results:1.Through two rounds of Delphi expert consultation survey and evaluation based on relevant coefficients,experts have a concentrated understanding of TCM syndromes and syndrome types of diabetic gastroparesis and have a relatively consistent understanding.2.Through two rounds of investigation,experts had a concentrated and clear understanding of the TCM syndrome types of diabetic gastroparesis.In both rounds,more than 50% of experts believed that the 7 syndrome types of spleen and stomach weakness,phlegm dampness obstruction,liver depression and spleen deficiency,spleen deficiency dampness,dampness and heat accumulation,qi and Yin deficiency and liver qi invasion of stomach were common.In the second round,more than 60% of the experts believed that spleen and stomach weakness syndrome(60.7%)and phlegm-dampness obstruction syndrome(60.7%)were common.Therefore,spleen and stomach weakness syndrome and phlegm-dampness obstruction syndrome were the most common syndrome types in diabetic gastroparesis patients.In the importance score,these 7 syndromes also got the highest score,and were sorted according to the score: syndrome of spleen and stomach weakness,syndrome of dampness and phlegm,syndrome of liver depression and spleen deficiency,syndrome of dampness and dampness of spleen deficiency,syndrome of dampness and heat accumulation,syndrome of qi and Yin deficiency,and syndrome of liver qi invading stomach.3.From all the expert consultation surveys,we can see that the coefficient of variation of the certificate type items in each round is less than 0.3,and the mean value of the significance evaluation of the certificate type items in the two rounds is greater than 3,and the authority coefficient of the experts is greater than 0.7,so the experts have a certain grasp and authority for the judgment of the certificate type.It can be seen that experts have a highly unified understanding of the TCM syndrome types and items of diabetic gastroparesis,so only two rounds of questionnaires were used in this Delphi survey.Conclusion:According to two rounds of Delphi expert questionnaire,the common TCM syndromes of diabetic gastroparesis are: spleen and stomach weakness,phlegm and dampness obstruction,liver depression and spleen deficiency,spleen and dampness accumulation,dampness and heat accumulation,qi and Yin deficiency,liver and qi invading stomach.Weakness of spleen and stomach and obstruction of phlegm and dampness were the most common in diabetic gastroparesis.
