Visibility of medical informatics regarding bibliometric indices and databases.

Spreckelsen C, Deserno TM, Spitzer K - BMC Med Inform Decis Mak (2011)

Bottom Line: This study examines the effects of the new indices on the visibility of Medical Informatics.The availability of index data (index coverage) and the aggregate scores of these corpora are compared for journal-related (Journal impact factor, Eigenfactor metrics, SCImago journal rank) and author-related indices (Hirsch-index, Egghes G-index).The visibility of smaller technology-oriented disciplines like Medical Informatics is changed by the new bibliometric indices and databases possibly leading to suitably changed publication strategies.

ABSTRACT

Background: The quantitative study of the publication output (bibliometrics) deeply influences how scientific work is perceived (bibliometric visibility). Recently, new bibliometric indices and databases have been established, which may change the visibility of disciplines, institutions and individuals. This study examines the effects of the new indices on the visibility of Medical Informatics.

Methods: By objective criteria, three sets of journals are chosen, two representing Medical Informatics and a third addressing Internal Medicine as a benchmark. The availability of index data (index coverage) and the aggregate scores of these corpora are compared for journal-related (Journal impact factor, Eigenfactor metrics, SCImago journal rank) and author-related indices (Hirsch-index, Egghes G-index). Correlation analysis compares the dependence of author-related indices.

Results: The bibliometric visibility depended on the research focus and the citation database: Scopus covers more journals relevant for Medical Informatics than ISI/Thomson Reuters. Journals focused on Medical Informatics' methodology were negatively affected by the Eigenfactor metrics, while the visibility profited from an interdisciplinary research focus. The correlation between Hirsch-indices computed on citation databases and the Internet was strong.

Conclusions: The visibility of smaller technology-oriented disciplines like Medical Informatics is changed by the new bibliometric indices and databases possibly leading to suitably changed publication strategies. Freely accessible author-related indices enable an easy and adequate individual assessment.

Mentions: The average score a as defined in (3) was calculated for JIF, ES, AIS, HI(SCI), and SJR. The comparison of the different indices was enabled by expressing the scores reached by MeSH-MI and Schuemie corpus as a percentage of the MeSH-Med-based benchmark (Figure 3). Irrespective of the bibliometric indices, all MI-related corpora scored below 56% of the medical corpus (MeSH-Med).
