[Spanish doctoral dissertations on anesthesiology and the scientific publications of their authors].
OBJECTIVE
To determine whether obtaining a doctorate is a factor that promotes the research careers of the authors. To analyze the dissemination of Spanish doctoral theses in anesthesiology by looking at the publications they generate.


METHODS
The TESEO data base was searched for theses on anesthesiology written between 1976 and June 2001. The Medline database was then searched for publications related to each author's thesis. The search identified papers related to each thesis as well as those in which the thesis director was a coauthor.


RESULTS
Two hundred twenty-eight theses (9.12 theses/year) were found. Twenty-four authors were not anesthesiologists. The universities of Barcelona (28), Valencia (24), Navarra (23), Autónoma de Barcelona (21), Complutense de Madrid (18) and Cádiz (18) accounted for most of the theses read. The doctoral degree recipients also co-authored 1,833 publications, as the first authors of 649 articles, of which 216 (33.3%) were published before the corresponding thesis was read. Only 127 articles were related to theses. Ninety-seven authors (42.5%) published no article as first author and 22 (9.6%) accomplished no publication as co-author. The thesis director was listed in 154 of the 228 theses in the TESEO database. In this subgroup, 39 doctoral thesis authors published 58 related articles, with the director included among the co-authors in 41 of them.


CONCLUSIONS
Spain produces few doctoral theses on anesthesiology. Most writers of doctoral theses do not publish the results in journals with international readerships. These findings call into question the efficacy of the doctoral thesis as a factor that promotes research.
