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.
