[Dutch authors in international medical journals are also authors of publications in the Nederlands Tijdschrift voor Geneeskunde (Dutch Journal of Medicine)].
OBJECTIVE
To determine whether Dutch medical scientists who frequently publish in international journals with high impact factors also publish in Dutch in the Nederlands Tijdschrit voor Geneeskunde (NTvG).


METHODS
Bibliometric study.


METHODS
By means of a search in Medline, the Dutch authors were selected who had published the largest number of articles in 20 medical journals with high impact factors from 5 different specialties: general medicine, surgery, dermatology, psychiatry and ophthalmology. Subsequently, it was determined how often these authors had published in the NTvG in the same period. Moreover, a countwas made of the number of articles the first authors of original articles in the NTvG in 1991 and 2000 had published in international journals in 1993-1997 and 1998-2002, respectively.


RESULTS
A large proportion of the Dutch investigators with many publications in international journals also published in the NTvG: in 1988-1992, 46 authors wrote 219 international publications and 35 of these published 151 articles in the NTvG; in 1998-2002, 55 authors wrote 326 international publications and 41 of these published 145 articles in the NTvG. The proportion of original articles published by these authors in the NTvG was lower than in the international journals: 83% for the international journals in 1998-2002 versus 39% for the NTvG in 2000. In 2001, 93 original articles by 87 different first authors appeared in the NTvG. Of these 87 authors, 67 (77%) published at least one article and 18 (21%) published more than 10 articles in an international journal in the period 1998 to 2002, as either the first author or a co-author.


CONCLUSIONS
Authors that publish many articles in frequently cited international journals also write articles for the NTvG and, vice versa, the authors of articles in the NTvG also publish in international journals.
