[Visualization analysis of literature on sudden poisoning incidents in China from 2013 to 2022 based on CiteSpace and VOSviewer].

<b>Objective:</b> To use CiteSpace and VOSviewer software to perform visualization analysis on research literature on sudden poisoning incidents in China from 2013 to 2022, in order to grasp the research hotspots and priorities, current research development status and trend of sudden poisoning incidents, and provide reference and ideas for subsequent research. <b>Methods:</b> In October 2023, literature related to sudden poisoning incidents was searched using the China National Knowledge Infrastructure and Wanfang databases. The bibliometric analysis software CiteSpace 6.1.R2 and VOSviewer 1.6.19 were used to visually analyze factors such as authors, institutions, journals, regions, and keywords in the relevant literature. <b>Results:</b> A total of 2578 valid literatures were included, and the overall number of published literatures showed a discontinuous downward trend in recent 10 years. The relevant literature was distributed in 310 journals. Among the top 10 institutions with the highest number of publications, 8 were centers for disease control and prevention at all levels, and the institution with the highest number of publications was the Chinese Center for Disease Control and Prevention (208 articles), but the cooperation between institutions was not obvious. The 2578 articles involved a total of 6549 authors (a total of 8572 appearances, with an average of 1.31 times per person), with a collaboration rate of 2.54 (6549/2578) and 2153 co-authored articles (with 2 or more authors in the literature), with a co-authorship rate of 83.51%. 643 articles (24.94%) received funding support. The region with the highest number of publications was Guangdong Province, with a total of 380 articles (14.74%). Keyword highlighting analysis showed that the research heat of pesticide poisoning, toxic mushrooms, disease characteristics, outbreak events, traceability analysis, outbreaks, and occupational diseases continued to 2022. <b>Conclusion:</b> There are many literatures on sudden poisoning incidents in China, so it is necessary to strengthen the cooperation and communication between institutions and authors. In practical work, the ability of prevention, control, and detection of poisons should be continuously improved to reduce the incidence and degree of harm caused by sudden poisoning incidents.
