To investigate the evolving trends and hot points in the research of geriatric emergency medicine (GEM) over the past decade.

Conduct a field search in the core collection database of Web of Science using "geriatric emergency medicine" as the subject. The literature was analyzed visually using Citespace software, and Excel was utilized to create an annual trend chart for the number of published documents and a trend prediction chart for high-frequency words. Additionally, an online geographic visualized heat map of country publication volume was generated using datawrapper software.

A total of 2 562 literatures were included for visual analysis. The number of articles from 2012 to 2021 showed a increasing trend, and a more substantial increase was observed after 2015, with the number of publications in 2021 being approximately 2.5 times that of 2012. The top three countries in terms of publication volume are the United States (827 articles), China (661 articles, including 452 articles from Taiwan Province), and Canada (183 articles). The top three intermediary centrality rankings are the United States (0.24), Ukraine (0.13), and the United Kingdom (0.12). The high-frequency keyword detection results show that the frequency of "risk factor" is 538 times, ranking first; The frequency of "predictor" is 370, ranking fifth. The trend forecast chart indicates that these two areas represent the current research frontier, with an increasing trend over the years. Cluster analysis resulted in the identification of 8 distinct topics, with a Q value of 0.7548 and an S value of 0.9032.

The international research in the field of geriatric emergency medicine is gaining increasing popularity, and the future GEM research in China will reach a threshold peak. Among them, the focus and emphasis of GEM research lies in the study of risk factors and predictive factors. The research direction of GEM treatment in hospitals can concentrate on emergency room treatment, emergency general surgery treatment, palliative care, and prognosis assessment.
