Abstract:
Aim: To evaluate number and quality of publications in gastroenterology,
hepatology and digestive endoscopy from Western Europe (Belgium, Denmark,
France, Germany, Great Britain, Italy, the Netherlands, Spain, Sweden,
Switzerland), Japan and USA over a recent 5-year period. Methods: We
screened by computer for full liver/ gastrointestinal-related articles and
reviews the top 40% of journals (according to the annual rating of the SCI
Journal Citation Reports; institute for Scientific Information database)
in most clinical and basic science disciplines in the years 1992-1996. To
be credited with an article, a given country had to be the site of the
first institution where the work was conducted. Papers were rated
according to the impact factor of the Institute for Scientific Information
and to the ratio impact factor/mean European impact factor. Data were also
normalized for nondefense research and development expenditure.

Results and Conclusions: As randomly tested, the computer search had an
error of +/-5-10%. In Europe, Great Britain achieved the highest total
impact factor and the highest number of papers. Most of the British impact
factor came from publications in British journals. The total USA
impact factor exceeded that of Europe by 20%. The average impact factor
for a single paper was highest for the USA and, in Europe, for Germany.
The temporal trend of total impact factor showed Spain improving
by 9% per year, with Germany and Italy also displaying a
substantial growth. Expressed per funds allocated in nondefense research
and development, Great Britain and the USA had the highest
cumulative impact factor. Copyright (C) 2000 S. Karger AG, Basel.
