BACKGROUND: The Hirsch index (h-index) is recognized as an effective way to summarize an individual's scientific research output. However, a benchmark for evaluating surgeon scientists in the field of hepatic surgery is still not available. METHODS: A total of 3,251 authors who published between 1949 and 2011 were identified using the Scopus identification number. The h-index, the total number of cited document, the total number of citations, and the scientific age were calculated for each author using both Scopus and Google Scholar. RESULTS:The median h-index was 6 and the median scientific age, assessed with Google Scholar, was 19 years. The numbers of cited documents, numbers of citations, and h-indexes obtained from Scopus and Google Scholar showed good correlation with one another; however, the results from the 2 databases were modified in different ways by scientific age. By plotting scientific age against h-index percentiles an h-index growth chart for both Scopus database and Google Scholar was provided. CONCLUSIONS: This analysis provides a first benchmark to assess surgeon scientists' productivity in the field of liver surgery.

Abstract
BACKGROUND: The Hirsch index (h-index) is recognized as an effective way to summarize an individual's scientific research output. However, a benchmark for evaluating surgeon scientists in the field of hepatic surgery is still not available. METHODS: A total of 3,251 authors who published between 1949 and 2011 were identified using the Scopus identification number. The h-index, the total number of cited document, the total number of citations, and the scientific age were calculated for each author using both Scopus and Google Scholar. RESULTS:The median h-index was 6 and the median scientific age, assessed with Google Scholar, was 19 years. The numbers of cited documents, numbers of citations, and h-indexes obtained from Scopus and Google Scholar showed good correlation with one another; however, the results from the 2 databases were modified in different ways by scientific age. By plotting scientific age against h-index percentiles an h-index growth chart for both Scopus database and Google Scholar was provided. CONCLUSIONS: This analysis provides a first benchmark to assess surgeon scientists' productivity in the field of liver surgery.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
