Meetings are an important way of exchanging scientific information, but full diffusion of new information can only be achieved when results are published in scientific journals.
(1) To determine the publication frequency of accepted abstracts for the yearly international conferences on pharmacoepidemiology (ICPE) and to examine predicting variables; (2) if published, to determine impact differences between 'oral' and 'poster' abstracts and to determine type and nature of publishing journals.
Abstracts accepted for ICPE 1995-1999, published in the official conference supplement of Pharmacoepidemiology and Drug Safety, were included. Publication status for the information contained in each abstract was evaluated through MEDLINE and IPA searches. Impact factors of publishing journals were retrieved and journals were included in one of five groups.
Overall, one out of three abstracts resulted in a publication in the peer-reviewed journals studied. Abstracts from North America were more often presented orally than abstracts from Europe, but had lower publication chances. 'Oral' abstracts were more likely to be published than 'poster' abstracts; abstracts with a strong methodological content had a lower publication frequency. Most of the published abstracts were found in pharmacology and pharmacy journals (33%) and journals on specific clinical topics (30%).
Only one out of three papers presented at ICPE ends up in established peer-reviewed journals. Although the publication characteristics for ICPE are not very different from other conferences, there are certain questions that warrant further investigation.
会议是交流科学信息的重要方式，但只有当研究结果在科学期刊上发表时，新信息才能得到充分传播。
（1）确定每年国际药物流行病学会议（ICPE）录用摘要的发表频率，并研究预测变量；（2）若已发表，确定“口头”摘要和“海报”摘要的影响力差异，并确定发表期刊的类型和性质。
纳入1995 - 1999年ICPE录用并发表于《药物流行病学与药物安全》官方会议增刊的摘要。通过检索MEDLINE和IPA评估各摘要所含信息的发表状态。检索发表期刊的影响因子，并将期刊分为五组之一。
总体而言，在所研究的同行评审期刊中，每三篇摘要中有一篇得以发表。来自北美的摘要比来自欧洲的摘要更多地以口头形式展示，但发表机会较低。“口头”摘要比“海报”摘要更有可能发表；方法学内容较强的摘要发表频率较低。大多数已发表的摘要发表在药理学和药学期刊（33%）以及特定临床主题的期刊（30%）上。
在ICPE上展示的论文中，只有三分之一最终发表在知名的同行评审期刊上。尽管ICPE的发表特征与其他会议没有太大差异，但仍有一些问题值得进一步研究。
