Background and objective: To assess the publication rate of full papers presented as abstracts at the 1995 meeting of the European Society of Anaesthesiologists, and to assess factors that might predict subsequent full publication.

Methods: All abstracts presented at the meeting and published in the British Journal of Anaesthesia (Suppl 1, 1995) were included. To verify subsequent full publication, a MEDLINE search was performed and validated. We studied the average time from the meeting to publication, the first author's country, the subspeciality, the publishing journal of the full report, the type of presentation (oral or poster), the object of investigation, and the quality of research design and of statistical reporting in the abstract.

Results: Of 472 meeting abstracts, 199 (42.2%) were eventually published. The average (± SD) delay between meeting and publication was 16.8 (15.6) months (range 24–60 months). Most papers (79.4%) had been published within 3 yr of the meeting. Circulation, pharmacology and intensive care papers had the highest rates of publication. Sixty-three journals attracted papers, with the British Journal of Anaesthesia publishing most (n = 29). No difference in subsequent publication was found between oral and poster presentations. Randomized trials and animal research were more likely to be published. The number of authors or their positions differed between the abstract and the full publication in 145 cases (72.9%); the first author was changed in 43 cases.

Conclusions: Less than half of the abstracts accepted at the 1995 European Society of Anesthesiologists' meeting were subsequently published in journals indexed by MEDLINE in the 3 yr following the meeting. Many changes in authorship occurred between the abstract and the full publication. The study architecture and the object of investigation predicted full publication.
