Although publications have been increasing rapidly, the research quality has yet to improve in the field of critical care medicine (CCM) in China. This study aimed at investigating the current status of and the influential factors for impactful publications in CCM research by Chinese authors.
Publications by authors with the affiliation of critical care medicine department or intensive care unit (CCM/ICU) in Chinese as well as American hospitals from 2001 to 2020 were retrieved from the Web of Science Core Collection (WoSCC) database for this bibliometric analysis. Moreover, statistical analyses to test factors affecting impactful publications by Chinese authors were performed.
Of 13,487 articles retrieved by this search strategy, 6,622 were published by Chinese authors as first or corresponding authors. The annual publications by Chinese authors have been rapidly increasing from 2001 to 2020, and so did the citations to these articles. However, the proportion in the world of publications by Chinese authors was much less than that by American authors each year [ (IQR): 1.85 (9.592) vs. 27.77 (7.3), < 0.001]. In addition, impactful articles were significantly less published by Chinese than by American authors, including articles either in journals with a high impact factor ( < 0.001) or in the top 10 journals in the field of CCM (5.4 vs 13.4%, < 0.001), and articles with high citation frequency as well ( < 0.001). Moreover, the percentage of impactful publications by Chinese authors was likely associated with academic background and regions of the author's affiliations, funds support, public health events of COVID-19, and collaboration between authors.
Our results demonstrated that CCM research in China grew rapidly in the recent 20 years. However, the impactful publications remained limited, largely owing to the shortage of comprehensive research training, inactive collaboration, and underfunded CCM research.
尽管中国重症医学领域的文献数量增长迅速，但研究质量仍有待提高。本研究旨在调查中国作者在重症医学研究中高影响力出版物的现状及影响因素。
通过文献计量分析，从科学引文索引核心合集（WoSCC）数据库中检索2001年至2020年中国和美国医院重症医学科或重症监护病房（CCM/ICU）作者发表的文献。此外，还进行了统计分析，以检验影响中国作者高影响力出版物的因素。
通过该检索策略共检索到13487篇文章，其中6622篇由中国作者作为第一作者或通讯作者发表。2001年至2020年，中国作者的年发文量迅速增加，这些文章的被引次数也在增加。然而，中国作者每年在全球出版物中所占的比例远低于美国作者[四分位间距（IQR）：1.85（9.592）对27.77（7.3），P<0.001]。此外，中国作者发表的高影响力文章明显少于美国作者，包括发表在高影响因子期刊上的文章（P<0.001）、发表在重症医学领域前10名期刊上的文章（5.4%对13.4%，P<0.001）以及被引频次高的文章（P<0.001）。此外，中国作者高影响力出版物的比例可能与作者的学术背景、所属地区、资金支持、新冠疫情公共卫生事件以及作者之间的合作有关。
我们的研究结果表明，中国重症医学研究在近20年中发展迅速。然而，高影响力出版物仍然有限，这主要是由于缺乏全面的研究培训、合作不活跃以及重症医学研究资金不足。
