[Scientific publications from the Spanish anesthesiology departments in 1989-1998. Authorship of the articles].
OBJECTIVE
To quantify the scientific publication of Spanish anesthesiologists and analyse article authorship.


METHODS
Bibliometric study. On MEDLINE we identified articles from Spanish anesthesiology departments published between 1989 and 1998. An entry for each article was created to record name, number and order of authors, journal source and length of article. The data base also noted where the article was published (Spain or abroad). Several bibliographic indices were calculated (authors per article, pages per article, articles per year, and more). The number of articles published by Spanish anesthesiologists was compared to the number published around the world.


RESULTS
We analyzed 604 articles from 12 Spanish journals and 176 from 40 foreign journals. The numbers of authors per article in Spanish publications during the first and last three-year periods were 4.86 and 5.28, respectively (p < 0.05). The numbers of authors per article published abroad for the same periods were 5.73 and 5.01, respectively. The number of pages published in international journals in the last three-year period was four-fold greater than in the first.


CONCLUSIONS
The bibliographic indices that reflect publication by Spanish anesthesiologists internationally is evolving positively. Data from Spanish journals allow us to deduce the existence of a certain degree of unjustified addition of authors. A quantitative-qualitative method for rating curriculum vitae is proposed in order to reduce that tendency.
