Aims - To examine the volume and potential impact of gastroenterology
research outputs from 1985 to 1998 from 14 developed countries; the overlap
with research in cancer, infectious diseases, and genetics; and the funding
sources for this research. To determine if countries' research outputs
correlated with their burden of corresponding diseases and inputs to their

Methods - Selective retrieval of papers from the Science Citation Index and
manual look up of a sample to determine funding sources. Classification of
journals by four categories of research level (clinical/basic) and
potential impact (low/high).

Results - Gastroenterology represents about 8% of world biomedical research
but over 11% in Italy, Japan, and Spain. Its potential impact is highest
(but declining) for the USA. It has increased noticeably in most European
countries, particularly in Finland. Gastroenterology research has become
more clinical in Japan, Spain, Australia, and the Netherlands but more
basic in Canada, Germany, Finland, Israel, and South Africa. Funding comes
primarily from national governments, followed by national private non-
profit sources and industry but little industrial funding occurs in some
countries. There is a strong and positive correlation between reported
deaths from gastrointestinal neoplasms and countries' outputs of research
in gastrointestinal oncology.

Conclusions - Bibliometric analysis can reveal differences between
countries in their research in a subject when a common methodology is
applied to an international database. Variations in research methods in
different countries can plausibly explain some of the variation in the
potential impact of the work.
