The quality of abstracts presented at medical conferences reflects the scientific activity in the organisations involved. The aims of this study were to evaluate the publication rate of studies presented at the annual congress of the German Society of Orthopaedics and Trauma Surgery and to investigate predictive factors for publication. The results were to be compared with other international meetings.
All 1,100 abstracts presented at the Congress of the German Society of Orthopaedics and Trauma Surgery in 2003 were assessed. The publication rate for the corresponding articles in peer-reviewed journals within 5 years was examined using a PubMed search. The consistency of the congress abstracts with the publications was studied. Factors influencing publication rates were investigated, including level of evidence (LoE) and type of study.
The publication rate was 36%, with a mean of 15 months between conference and publication (mean impact factor 1.50). No significant differences were observed between publication rates for oral presentations and posters. Experimental studies and those with LoE I and II had higher publication rates (47.1%; 55.2%; 39.8%) than clinical studies and those with LoE III and IV (30.8%; 29.2%; 28.0%). Abstracts of randomised studies and prospective studies showed publication rates of 43.2 and 35.6% and were published more often than abstracts of non-randomised studies and retrospective studies, with publication rates of 35.3 and 27.1%.
The publication rate was in the lower range of rates available for comparable conferences--e.g., the American Academy of Orthopaedic Surgeons, with rates between 34 and 55%--but lower than those of the Orthopaedic Trauma Association, at 52-67%. However, 64% of the abstracts remained unpublished, calling into question the acceptability of citing conference abstracts in the scientific literature and implementing them in clinical practice.
医学会议上展示的摘要质量反映了相关机构的科学活动水平。本研究旨在评估德国骨科创伤外科学会年会报告研究的发表率，并探讨其预测因素。研究结果将与其他国际会议进行比较。
评估了 2003 年德国骨科创伤外科学会年会报告的 1100 份摘要。使用 PubMed 搜索，调查了在 5 年内发表于同行评议期刊上的相应文章的发表率。研究了会议摘要与出版物的一致性。研究了影响发表率的因素，包括证据水平（LoE）和研究类型。
发表率为 36%，会议与发表之间的平均时间为 15 个月（平均影响因子为 1.50）。口头报告和海报的发表率无显著差异。实验研究和 LoE I 和 II 的研究发表率较高（47.1%；55.2%；39.8%），而临床研究和 LoE III 和 IV 的研究发表率较低（30.8%；29.2%；28.0%）。随机研究和前瞻性研究的摘要发表率分别为 43.2%和 35.6%，高于非随机研究和回顾性研究的摘要发表率，分别为 35.3%和 27.1%。
发表率处于可比较会议（如美国骨科医师学会，发表率在 34%至 55%之间）的较低范围，但低于骨科创伤协会的 52%-67%。然而，64%的摘要仍未发表，这对在科学文献中引用会议摘要和将其应用于临床实践的可接受性提出了质疑。
