OBJECTIVE: To probe into the epidemiological characteristics of adverse drug reactions（ ADR）induced by traditional Chinese medicine injections in Wuzhou

Guangxi Zhuang Autonomous Region（ Hereinafter referred to as "Wuzhou"）. METHODS: ADR reports induced by traditional Chinese medicine injections in Wuzhou from 2011 to 2019 were collected. Microsoft ACCESS software was used to establish the database

and SPSS Modeler14. 1 data mining platform was used to carry out data mining research based on CART

CHAID decision tree algorithm and Bayesian network methods. RESULTS: A total of 1 370 detailed cases of ADR induced by traditional Chinese medicine injections were collected

of which 1 239 cases were general（ 90. 44%） and 131 cases were severe（ 9. 56%）. The results of Bayesian network analysis showed that the clinical manifestations of ADR induced by traditional Chinese medicine injection were related to the age of patients. In the age group of > 60 years old

the proportion of skin damage gradually decreased

and the proportion of other system damage gradually increased. The results of cart algorithm showed that the main clinical manifestation of ADR was skin damage

and skin damage was the main manifestation of ADR in all age groups. The results of decision tree CHAID algorithm show that the main clinical manifestation of ADR was skin damage

the general ADR was mainly skin damage

and the serious ADR were mainly systemic damage and respiratory damage.. CONCLUSIONS: The epidemiological characteristics of ADR induced by traditional Chinese medicine injections in Wuzhou may be related to the age of patients

occurrence time of ADR and types of ADR

which need to be analyzed and verified by data analysis of a larger sample size.
