- Abstract: Objective To provide basis for the formation of acute exacerbation of chronic obstructive pulmonary disease(AECOPD-STES),the item weight of the syndrome therapeutic evaluation scale for AECOPD-STES was determined.Methods Based on the clinical survey data of 387 AECOPD patients,the random forest method was adopted,and the Spyder integrated development environment.Anaconda navigator software was used to call the"random forest Classifier"in the sklearn package to establish the initial random forest model and calculate the item weights.Factor analysis was used to extract common factors with cumulative variance contribution>80%,and the item weight was calculated according to the cumulative variance contribution and component score coefficient of common factors.The percentage weight method was used to calculate the item weight based on the importance score of each item by 29 experts.Finally,40%,30%and 30%of the above three methods were given respectively to determine the final weight of the items.Results The random forest method showed that the weights of wind cold syndrome,cold Yin syndrome,phlegm heat syndrome,phlegm dampness syndrome and blood stasis syndrome were 0.014-0.170,0.076-0.194,0.017-0.183,0.010-0.183 and 0.069-0.298,respectively.Factor analysis showed that the weights of wind cold syndrome,cold yin Syndrome,phlegm heat syndrome,phlegm dampness syndrome and blood stasis syndrome were 0.030-0.111,0.100-0.182,0.037-0.095,0.022-0.141 and 0.054-0.185,respectively.The percentage weight method shows that the weight ranges of wind cold syndrome,cold yin Syndrome,phlegm heat syndrome,phlegm dampness syndrome and blood stasis syndrome were 0.072-0.102,0.146-0.182,0.057-0.077,0.075-0.111 and 0.115-0.185,respectively.According to the three methods,the weights of wind cold syndrome,cold yin Syndrome,phlegm heat syndrome,phlegm dampness syndrome and blood stasis syndrome were 0.050-0.121,0.117-0.174,0.040-0.117,0.056-0.130 and 0.092-0.188,respectively.Conclusion This study determined the weight of each item of AECOPD-STES,providing a basis for the calculation of syndrome score.
