The SARS-CoV-2 pandemic has led to profound limitations in patient care and student teaching at the University Hospitals of Otorhinolaryngology (ORL). In contrast, the impact on research has been variable. To classify the pandemic-related effect on research, the development of the number of scientific publications of the German ORL university hospitals before and during the pandemic was analyzed.
The publication performance between 2015 and 2020 of the 39 current chairmen was surveyed using a literature search (Pubmed). All entries relating to the chairmen of the university hospital as first, last or co-author were included. The absolute and relative development of each author's publication performance was determined and evaluated using nonparametric statistical methods.
A total of 2420 publications could be documented. From 2015 to 2019, an average of 368 publications were published per year. In 2020, this number increased by 57.9 % to 581 publications. While the number of monthly publications remained constant between 2015 and 2019, a significant increase was seen from May 2020 up to a maximum of 74 publications in September 2020. In 2020, 34 articles (5.9 %) had a thematic relation to the SARS-CoV-2 pandemic, with 7 of these papers (20.6 %) resulting from cross-site publications.
In 2020, the number of scientific publications was raised to more than 1.5 times the usual annual publications. This increase was clearly related in time to the reduction of elective patient care during the SARS-CoV-2 pandemic starting in mid-March 2020. Probably, free time capacities enabled this increased publication output. Our results confirm the great scientific potential of the ORL university hospitals, which has been successfully implemented despite the pandemic.
严重急性呼吸综合征冠状病毒2（SARS-CoV-2）大流行给耳鼻咽喉科大学医院的患者护理和学生教学带来了极大限制。相比之下，对研究的影响则各不相同。为了分类大流行对研究的相关影响，分析了德国耳鼻咽喉科大学医院在大流行之前和期间科学出版物数量的变化情况。
通过文献检索（PubMed）调查了39位现任主任在2015年至2020年期间的发表情况。纳入所有将大学医院主任列为第一作者、最后作者或共同作者的条目。使用非参数统计方法确定并评估每位作者发表情况的绝对和相对变化。
总共记录了2420篇出版物。2015年至2019年，每年平均发表368篇出版物。2020年，这一数字增长了57.9%，达到581篇出版物。虽然2015年至2019年每月的出版物数量保持不变，但从2020年5月开始显著增加，到2020年9月最多达到74篇。2020年，34篇文章（5.9%）与SARS-CoV-2大流行有主题关联，其中7篇论文（20.6%）来自跨机构合作发表。
2020年，科学出版物数量增加到通常年出版物数量的1.5倍以上。这一增长在时间上与2020年3月中旬开始的SARS-CoV-2大流行期间择期患者护理的减少明显相关。可能是空闲时间使得出版物产量增加。我们的结果证实了耳鼻咽喉科大学医院巨大的科研潜力，尽管有大流行，这种潜力仍得到了成功发挥。
