Description
Summary:To determine author and journal self-citation rates in a sample of original emergency medicine (EM) research articles. We undertook a retrospective observational study of original research articles published in 2019 in the top six English language general EM journals. Data comprised the total numbers of articles, citations, authors and self-citations for each author (author self-citations) as well as the number of articles in the reference list that had been previously published in the same journal (journal self-citations). 3213 individual authors and 581 articles were examined. Most authors did not self-cite at all although 62 self-cited five or more times in a single article. The mean (SD) and median (IQR) numbers of individual author self-citations/article/year were 0.6 (1.3) and 0 (0–1), respectively. Overall, author self-citations accounted for 2.4% of all cited articles. There was a weak positive but significant correlation between the number of individual author self-citations/article/year and the number of articles published by the author (r = 0.38, p
