The aims of this study were to investigate authorship trends among publications in high-impact, peer-reviewed specialty journals published within the last decade and to assess how publication practices differ among medical specialties.
The National Institutes of Health's Portfolio Analysis platform, iCite, was queried for PubMed-indexed case reports, review articles, and original research articles published between 2005 and 2017 in 69 high-impact, clinical journals encompassing 23 medical specialties. Overall, 121,397 peer-reviewed publications were evaluated-of which, 45.1% were original research, 28.7% were review articles, and 26.3% were case reports. Multivariable regression was used to evaluate the magnitude of association of publication year on the number of authors per article by specialty and article type.
Original research articles have the greatest increase in authorship (0.23 more authors per article per year), as compared with review articles (0.18 authors per article per year) and case reports (0.01 authors per article per year). Twenty-two of the 23 specialties evaluated had increase in authorship in high-impact specialty journals. Specialty growth rates ranged from 0.42 authors/year (Neurology), Psychiatry (0.35 authors/year), General Surgery (0.29 authors/year), Urology (0.27 authors/year), and Pathology (0.27 authors/year). Specialties with a greater percentage of graduates entering academics had more authors per article; surgical specialties and length of residency were not found to be predictive factors.
There has been substantial growth in the authorship bylines of contemporary medical literature, much of which cannot be explained by increased complexity or collaboration alone.
本研究旨在调查过去十年内发表的高影响力、同行评审专业期刊上的论文署名趋势，并评估医学各专业的发表模式有何不同。
通过美国国立卫生研究院的投资组合分析平台iCite，查询2005年至2017年间发表在69种涵盖23个医学专业的高影响力临床期刊上、被PubMed收录的病例报告、综述文章和原创研究文章。总体而言，共评估了121397篇经同行评审的出版物，其中45.1%为原创研究，28.7%为综述文章，26.3%为病例报告。采用多变量回归分析按专业和文章类型评估发表年份与每篇文章作者数量之间的关联程度。
与综述文章（每年每篇文章增加0.18名作者）和病例报告（每年每篇文章增加0.01名作者）相比，原创研究文章的作者数量增加最多（每年每篇文章增加0.23名作者）。在评估的23个专业中，有22个专业在高影响力专业期刊上的作者数量有所增加。专业增长率从每年0.42名作者（神经病学）、精神病学（每年0.35名作者）、普通外科（每年0.29名作者）、泌尿外科（每年0.27名作者）和病理学（每年0.27名作者）不等。进入学术界的毕业生比例较高的专业，每篇文章的作者更多；未发现外科专业和住院医师培训时长是预测因素。
当代医学文献的作者署名数量大幅增加，其中许多无法仅用复杂性增加或合作增多来解释。
