A 10-year bibliometric analysis of publications in emergency medicine

Objective: Emergency medicine (EM) research is growing at a rapid pace. It is important to understand the scope and trends over time in order to identify gaps and future areas for growth. This study aimed to describe trends in scientific publications within EM over the past decade.

Methods: We searched the Web of Science database's Emergency Medicine category for all scientific publications published between 2010 and 2019. Data were presented via descriptive statistics. Inferential bibliometric analyses included clustering of the selected parameters of keywords, Keyword Plus, titles, and abstracts; Bradford's law to evaluate core journals, and the Sankey diagrams to evaluate the flows between research themes over time.

Results: We identified 32,858 articles written by 85,693 authors. The mean citations per document were 11. The top five countries with the highest number of publications were the United States (n = 42,221), Turkey (n = 6595), Canada (n = 6545), Australia (n = 5867), and China (n = 5322). The journals with the highest number of publications: the American Journal of Emergency Medicine, Journal of Emergency Medicine, Resuscitation, and Pediatric Emergency Care. The most frequent topics were cardiovascular emergencies, resuscitation, mortality, patient outcomes, emergency imaging, triage, education, and management.

Conclusion: This bibliometric study is a quick snapshot of research in the EM field in the last decade and may provide insights into the scientific agendas of the EM professionals.
