BackgroundEmergency medicine (EM) is a rapidly developing specialty worldwide. The scientific publications trend is one of the parameters to evaluate national EM developmental milestones. This study was performed to analyze the publication trends from emergency departments (EDs) of International Federation for Emergency Medicine (IFEM) full member countries from 2009 to 2018.MethodsAll data were retrieved from the SciVerse Scopus database. IFEM full member countries where EM was recognized as a specialty before 2009 and annual publication numbers exceeded 12 in 2018 were included. The EM journals list was adopted from the 2017 Journal Citation Reports. Publications with the first author affiliated with EDs were divided into EM or non-EM journal groups according to the publishing journal. The slope (β) of the linear regression was used to assess the trends of publication numbers. The correlation between the 2009 publication number and the trend of publication between 2009 and 2018 was measured by Pearson's correlation coefficient (r). The correlation between funding numbers and publication numbers was analyzed by Spearman's rank correlation coefficient (rs).ResultsWe identified 30,130 publications with first authors from EDs in 19 countries. The numbers of publications in both EM and non-EM journals showed an increasing trend in 12 countries. Fifteen of the 19 countries had a greater increasing trend in non-EM journals than in EM journals. The 2009 publication numbers were positively correlated with the publication increasing trend between 2009 and 2018 in both EM and non-EM journals (r = 0.854 and 0.947, respectively, both p < 0.001). The funded publication number was positively correlated with the total national publication amount (rs = 0.748, p < 0.001).ConclusionsThe research capacity of EDs has been increasingly recognized by other medical specialties. The national publication numbers from EDs may predict the academic publication increasing trends in the subsequent 10 years.Copyright © 2021 Elsevier Inc. All rights reserved.
