Abstract

PURPOSE
The purpose of this study was to analyze recent citation trends in an attempt to improve the impact factor (IF) of the Journal of the Korean Society of Emergency Medicine (JKEM). Data from 2001~2012 in the Korean Medical Citation Index (KoMCI) was compared with the average citation data of other Korean emergency medicine-related journals.
METHODS
All citation data from all journals listed in the KoMCI and the Web of Science were obtained. The chronological changes in the annual number of published articles and reference citations, total citations and self-citations per paper, IF and impact factor excluding self-citations (ZIF) were described and compared for Korean EM-related journals and the JKEM.
RESULTS
The annual number of articles published in JKEM was significantly larger than other EM-related journals. The number of Korean journal references per article is 2.13 papers on JKEM. The mean IF of the KoMCI was 0.153 and the ZIF was 0.050 for 12 years. The annual IF (ZIF) of JKEM has gradually decreased from 0.245(0.102) in 2010 to 0.118(0.035) in 2012. However, other EM-related journals have shown increases in these factors since 2009. The IF calculated from the Web of Science was zero until 2010, but soared from 0.008 to 0.016 from 2011 to 2012, respectively.
CONCLUSION
The citation status of JKEM has steadily decreased over the past 2 years. To make JKEM as a highly-cited journal, an awareness of the academic status of JKEM and active advertising from journal members on the importance of the IF are needed to encourage the citation of its papers.
