Abstract:
Objective:To analyze the knowledge graph of the papers published in the core journals of emergency medicine from 2015 to 2019, to present the overall situation of the research in the field of emergency medicine, to highlight the important contents in the research progress, and to unearth the research hotspots reported in the journals of emergency medicine.Methods:The relevant literatures of 7 core journals of emergency medicine were retrieved and exported from CNKI and Wanfang databases published in 2015-2019. A total of 7753 valid literatures were included. The visualization software CiteSpace was used to analyze the information of authors, institutions and keywords in the exported literatures to generate visual graphs.Results:By analyzing the knowledge graph from 2015 to 2019, it is found that Yu Xuezhong, Zhu Huadong, Zhang Jinsong, Zhang Mao, Liu Xinwei, Liu Yin, Xu Jun, and Nie Sinnan were the backbone of the author group in the field of emergency medicine. Emergency Department of Peking Union Medical College Hospital, Beijing Chaoyang Hospital Affiliated to Capital Medical University, Emergency Department of PLA General Hospital, Emergency Medicine Department of Eastern Theater General Hospital, Emergency Department of Xijing Hospital, and Emergency Medicine Department of Shenyang Military Region General Hospital were the institutions with the most publications. In recent 5 years, the core journals of emergency medicine focused on the topics on mortality, acute lung injury, cardiac arrest, prognosis, mechanical ventilation, acute myocardial infarction and hemoperfusion.Conclusions:The visual graphs generated by CiteSpace helps to intuitively understand the critical path, development trend and frontier hot spots of the evolution of the research field of emergency medicine, and provides more basis for future related research.
