In recent years, China is increasingly playing an active role in various fields of biomedical research. Many bibliometric studies have provided valuable insights to different fields of clinical studies. However, similar evaluation on spine surgery-related clinical research is still limited. We herein aimed to examine the scientific publications by orthopedic spine surgeons from mainland China within a 14-year period.
Articles were identified in PubMed using predetermined query terms. Descriptive statistics were calculated, and T tests, Chi-squared tests, and regression analysis were conducted on the number of publications, impact factors (IFs), citations, region of the study, and associated medical subject headings (MeSHs).
A total of 1498 articles were identified and the annual number of publications, citations, and IFs all increased exponentially. The average IF was significantly higher in 2007 to 2013 than 2000 to 2006. Most publications were from Shanghai and Beijing and the 5 most productive administrative regions generated 70% of all publications. Analysis of associated MeSHs suggested research topics became more heterogeneous over the study period.
This was the first comprehensive evaluation on the clinical research output by orthopedic spine surgeons from mainland China. The annual number of publications and citations both increased significantly; however, research was highly concentrated in a handful of administrative regions.
近年来，中国在生物医学研究的各个领域发挥着越来越积极的作用。许多文献计量学研究为临床研究的不同领域提供了有价值的见解。然而，对脊柱外科相关临床研究的类似评估仍然有限。我们在此旨在研究中国大陆骨科脊柱外科医生在14年期间的科学出版物。
使用预定的检索词在PubMed中识别文章。计算描述性统计量，并对出版物数量、影响因子（IFs）、引用次数、研究地区和相关医学主题词（MeSHs）进行t检验、卡方检验和回归分析。
共识别出1498篇文章，出版物数量、引用次数和IFs均呈指数增长。2007年至2013年的平均IF显著高于2000年至2006年。大多数出版物来自上海和北京，5个产出最多的行政区产生了所有出版物的70%。对相关MeSHs的分析表明，在研究期间研究主题变得更加多样化。
这是对中国大陆骨科脊柱外科医生临床研究产出的首次综合评估。出版物数量和引用次数均显著增加；然而，研究高度集中在少数几个行政区。
