Since its founding in 1989, the Society for Academic Emergency Medicine (SAEM) has accepted thousands of abstracts for presentation at its annual meeting. We reviewed abstracts to characterize temporal changes in study design, abstract topics, quality scores, and proportion of abstracts published as manuscripts.
In this serial cross-sectional study, we compiled accepted SAEM abstracts at 5-year intervals (1990, 1995, 2000, 2005, 2010, 2015, 2020) and then randomly selected 100 abstracts from each year for review by two investigators. We documented each abstract's study design, sample size, and whether it was a single-center or multicenter study. We assigned each abstract to the most appropriate topic category. Applying SAEM's abstract scoring system from 2020, we calculated the mean overall quality score per year. Finally, we searched PubMed to determine if abstracts from 1990-2015 meetings were published as manuscripts.
The number of accepted abstracts increased from 180 in 1990 to 879 in 2020 (+388%). The most common study design changed from laboratory study in 1990 (22%) to cohort study in 2020 (44%; p < 0.001). The median study sample size increased over time, from 105 (interquartile range [IQR] 25-389) in 1990 to 544 (IQR 102-2067) in 2020 (p < 0.001). Multicenter studies have become more common (19% in 1990 vs. 40% in 2020; p = 0.001). The most common topic categories also changed from cardiology/pulmonary/airway (40%) and orthopedic/trauma/burn (17%) in 1990 to health services research/health policy/operations (25%) and cardiology/pulmonary/airway (22%) in 2020. There was a 20% increase in overall quality scores (p < 0.001). Between 37% and 49% of the abstracts reviewed from each year were later published as manuscripts, with no significant change over time (p = 0.33).
Over the past 30 years, there have been significant changes to the study designs, topics, and quality scores of SAEM meeting abstracts. However, conversion of abstracts to published manuscripts remains a challenge.
自 1989 年成立以来，学术急救医学学会（SAEM）已接受了数千份论文摘要，以供其年会展示。我们对这些摘要进行了审查，以描述研究设计、摘要主题、质量评分以及摘要发表为论文的比例随时间的变化。
在这项连续的横断面研究中，我们每隔 5 年汇编一次接受的 SAEM 摘要（1990 年、1995 年、2000 年、2005 年、2010 年、2015 年、2020 年），然后从每年随机选择 100 篇摘要供两名研究人员审查。我们记录了每篇摘要的研究设计、样本量以及是否为单中心或多中心研究。我们将每篇摘要分配到最合适的主题类别。应用 2020 年 SAEM 的摘要评分系统，我们计算了每年的平均整体质量评分。最后，我们在 PubMed 上搜索 1990-2015 年会议的摘要是否发表为论文。
接受的摘要数量从 1990 年的 180 篇增加到 2020 年的 879 篇（增加了 388%）。最常见的研究设计从 1990 年的实验室研究（22%）变为 2020 年的队列研究（44%；p<0.001）。研究样本量中位数随时间增加，从 1990 年的 105（四分位距 [IQR] 25-389）增加到 2020 年的 544（IQR 102-2067）（p<0.001）。多中心研究变得更加普遍（19%在 1990 年与 40%在 2020 年；p=0.001）。最常见的主题类别也从 1990 年的心脏病学/肺病/气道（40%）和骨科/创伤/烧伤（17%）变为 2020 年的卫生服务研究/卫生政策/运营（25%）和心脏病学/肺病/气道（22%）。整体质量评分提高了 20%（p<0.001）。每年审查的摘要中有 37%至 49%后来发表为论文，但随时间变化没有显著变化（p=0.33）。
在过去的 30 年中，SAEM 会议摘要的研究设计、主题和质量评分都发生了重大变化。然而，将摘要转化为已发表的论文仍然是一个挑战。
