- Abstract: Objective:To construct "Expert consensus on diagnosis and treatment of chronic inducible urticaria in China (2023) " based on the Delphi method, and to provide a methodological basis for consensus construction.Methods:After systematic search and evaluation of the literature related to chronic inducible urticaria, the first draft of "Expert consensus on diagnosis and treatment of chronic inducible urticaria in China (2023) " was written, and a questionnaire was designed for expert consultation. A representative sample of 25 experts was selected to conduct two rounds of correspondence consultation via electronic questionnaire in strict accordance with the Delphi method, and the content of the consensus was revised and improved according to the consultation results.Results:The response rates in the two rounds of questionnaire consultation were both 100%, and the expert authority coefficient was 0.92 ± 0.09. In the first round of consultation, the coefficients of variation (CV values) of 9 items were greater than 20%, and the mean agreement degree of 3 items was less than 7 points; in the second round of consultation, the CV values of all items were less than 15%, the agreement degree of the above 3 items whose mean agreement degree was less than 7 points in the first round of consultation all rose to over 7 points, and the median agreement degree of all items was greater than or equal to 8 points. Reliability analysis of the two rounds of questionnaire results showed that the Cronbach α coefficient and standardized Cronbach α coefficient were both greater than 0.9; the P values in the agreement tests by using Kendall′s coefficient of concordance for the two rounds of questionnaire results were both less than 0.001, and the Kendall′s coefficients of concordance were 0.170 and 0.219 in the first and second rounds of questionnaire consultation, respectively. Conclusion:The Delphi method-based "Expert consensus on diagnosis and treatment of chronic inducible urticaria in China (2023) " is highly representative, authoritative and reliable; this study also provides a methodological reference for the formulation and research of consensus.
