Abstract

INTRODUCTION: Scholarly impact has been used to measure faculty productivity and academic contribution throughout academia. Traditionally, the number of articles authored has been the primary metric for scholarly impact regarding academic promotion and reputation. We hypothesize that over time, the nature of authorship has evolved to include more authors per research article throughout the history of orthopaedic literature. METHODS: Bibliometric data for all original research article abstracts were extracted from PubMED for the 10 highest rated H5-index orthopaedic clinical journals ("American Journal of Sports Medicine," "Journal of Bone and Joint Surgery American Volume," "Clinical Orthopaedics and Related Research "Spine," "Knee Surgery, Sports Traumatology, Arthroscopy," "Journal of Arthroplasty," "Arthroscopy," "The Spine Journal," "European Spine Journal," and "Journal of Bone and Joint Surgery British Volume/Bone & Joint Journal"). The number of authors per article was then analyzed over time using the Cochran-Armitage trend test. RESULTS: A total of 106,529 original articles were analyzed over a 70-year period. The number of authors increased significantly over time from a mean of 1.4 authors (SD: 0.62) in 1946 to 5.7 authors (SD: 3.1) in 2019, representing an average relative increase of 4.3% per year (P < 0.05). The three oldest journals had the lowest average authors (Journal of Bone and Joint Surgery Am Volume: 1946, mean 3.7 authors [SD: eight]; Journal of Bone and Joint Surgery Br Volume/Bone & Joint Journal: 1948, mean: 3.6 authors [SD: 7.5]; Clinical Orthopaedics and Related Research: 1963, mean 3.3 authors [SD: 2.9]). The three newest journals had the highest average authors (European Spine Journal: 1992, mean 5.3 authors [SD: 3.3]; Knee Surgery, Sports Traumatology, Arthroscopy: 1993, mean 5.5 authors [SD: 6.7 authors; The Spine Journal: 2003, mean 5.2 authors [SD: 3.6]). DISCUSSION: Original research articles published in orthopaedic academic journals have experienced an increase in authorship over time. Although our data cannot explain what has driven this change, increasing cooperation between collaborators may represent less contribution per author over time.

摘要

简介：学术影响力一直被用于衡量学术界教师的生产力和学术贡献。传统上，发表文章的数量一直是学术晋升和声誉的学术影响力的主要指标。我们假设，随着时间的推移，在骨科文献的历史中，作者的性质已经发展到包括每篇研究文章的更多作者。

方法：从 PubMED 中提取了 10 种评分最高的 H5 指数骨科临床期刊（“美国运动医学杂志”，“骨科与关节外科杂志美国卷”，“临床骨科与相关研究杂志”，“脊柱”，“膝关节外科、运动创伤学、关节镜”，“关节置换杂志”，“关节镜”，“脊柱杂志”，“欧洲脊柱杂志”和“骨科与关节外科杂志英国卷/骨与关节杂志”）的所有原始研究文章摘要的书目数据。然后使用 Cochran-Armitage 趋势检验分析随时间推移的文章作者数量。

结果：在 70 年的时间里，共分析了 106529 篇原始文章。作者数量随着时间的推移显著增加，从 1946 年的平均 1.4 位作者（标准差：0.62）增加到 2019 年的 5.7 位作者（标准差：3.1），平均每年增长 4.3%（P <0.05）。三个最古老的期刊的平均作者人数最低（骨科与关节外科杂志美国卷：1946 年，平均 3.7 位作者[标准差：8]；骨科与关节外科杂志英国卷/骨与关节杂志：1948 年，平均 3.6 位作者[标准差：7.5]；临床骨科与相关研究杂志：1963 年，平均 3.3 位作者[标准差：2.9]）。三个最新的期刊的平均作者人数最高（欧洲脊柱杂志：1992 年，平均 5.3 位作者[标准差：3.3]；膝关节外科、运动创伤学、关节镜杂志：1993 年，平均 5.5 位作者[标准差：6.7 位作者；脊柱杂志：2003 年，平均 5.2 位作者[标准差：3.6]）。

讨论：发表在骨科学术期刊上的原始研究文章的作者人数随着时间的推移而增加。尽管我们的数据无法解释是什么推动了这一变化，但随着时间的推移，合作者之间的合作增加可能意味着每个作者的贡献减少。
