The aim of this study was to evaluate the evolution of the citation of articles from the European Journal of Emergency Medicine (EJEM) from 1994 (EJEM foundation) to 2015 and identify highly cited articles and their principal characteristics and determine a possible correlation between the citations counted in different databases.
We obtained the articles published in EJEM from 1994 to 2015 in ISI-WoS (main source) and Scopus, Google Scholar, and Medline databases (accessory sources). The citations were quantified and their annual evolution and the bibliometric indices derived (impact factor and SCImago Journal Rank) were evaluated. We identified and analyzed the highly cited EJEM articles and evaluated the possible correlation between the citations counted for these articles in the databases.
Overall, 1705 EJEM articles were cited 9422 times in 8122 different articles. The evolution of the global citation, impact factor, and SCImago Journal Rank from 1994 to 2015 increased significantly. The h-index of EJEM was 30, and 31 articles were considered highly cited (≥30 citations), 16.1% of them being clinical trials. By subjects, 22.5% corresponded to cardiology, 19.3% to emergency department management, and 12.9% to pediatrics; by countries, 81% were from Europe, with Belgian authors publishing four (12.9%) highly cited articles, and French, Spanish, British, and Swedish authors having three (9.7%) each. Two studies in the EJEM achieved the definition of 'citation classics' (more than 100 citations). The number of citations in all the databases, except Medline, showed statistically significant correlations.
Citation of EJEM articles has progressively increased and EJEM bibliometric indicators have improved; most highly cited articles are mainly by European authors.
本研究旨在评估《欧洲急诊医学杂志》（EJEM）自 1994 年（EJEM 创刊）至 2015 年发表的文章的引用情况，并确定高被引文章及其主要特征，以及确定在不同数据库中计数的引文之间是否存在相关性。
我们从 ISI-WoS（主要来源）和 Scopus、Google Scholar、Medline 数据库（辅助来源）获取了 1994 年至 2015 年在 EJEM 上发表的文章。对引文进行了量化，并对其年度演变和衍生的计量学指标（影响因子和 SCImago 期刊排名）进行了评估。我们确定并分析了高被引的 EJEM 文章，并评估了这些文章在数据库中的引文计数之间可能存在的相关性。
总体而言，1705 篇 EJEM 文章在 8122 篇不同的文章中被引用了 9422 次。1994 年至 2015 年，全球引文、影响因子和 SCImago 期刊排名的演变显著增加。EJEM 的 h 指数为 30，有 31 篇文章被认为是高被引文章（≥30 次引用），其中 16.1%为临床试验。按主题划分，22.5%属于心脏病学，19.3%属于急诊科管理，12.9%属于儿科；按国家划分，81%来自欧洲，其中比利时作者发表了 4 篇（12.9%）高被引文章，法国、西班牙、英国和瑞典作者各有 3 篇（9.7%）。EJEM 中有两项研究达到了“引文经典”（超过 100 次引用）的定义。除 Medline 外，所有数据库中的引文数量均显示出具有统计学意义的相关性。
EJEM 文章的引用量逐渐增加，EJEM 计量指标得到了改善；大多数高被引文章主要来自欧洲作者。
