背景:科学书目制作的评估是一个复杂的问题,主要基于期刊的影响因子(IF)和h指数,量化作者收到的文章数量。为了估计西班牙神经外科医生的书目制作和共同作者的影响,我们进行了PubMed搜索,目的是确定神经外科医生样本发表的所有论文.
方法:横断面观察性和区域性研究。我们确定了来自马德里和卡斯蒂利亚·莱昂自治区的183名神经外科医生的样本。文献计量信息于2022年3月通过PubMed免费访问网站收集。对于每个作者,我们注册了期刊的类型,文章总数,出现在作者列表中的顺序,总IF,作为第一作者或第二作者签署的文章的比例(个人作者商[PAQ])和归因于这些文章的IF的百分比(个人影响商[PIQ])。
结果:共有来自183位作者的3,592篇文章发表在412种不同的期刊上,其中只有9.9%是纯神经外科杂志。只有17名神经外科医生(9.3%)发表了至少一篇文章作为独特作者。每位神经外科医生的平均文章数量为20(中位数9),其中57.7%发表在神经外科杂志上,和22,2%在Neurocirugía(SENEC的官方出版物)。平均PAQ为0.367(中位数0.364),平均PIQ为0.317(中位数0.251)。随着出版物数量的增加,这两个比例都有下降的趋势。
结论:平均而言,西班牙神经外科医生一半的文章发表在神经外科杂志上,在三分之一的案件中以第一或第二作者的身份出现,并且归因于这些纸张的IF占总IF的25%。PAQ和PIQ提供了文献计量信息,可最大程度地减少对大量合著者课程的扩大影响,并允许在作者和不同科学领域之间进行比较。
BACKGROUND: Assessment of scientific bibliographic production is a complex issue, mainly based on the impact factor (IF) of the journals and the h index, that quantifies the number of cites an author receives. In order to estimate the bibliographic production and the influence of co-authorship among Spanish neurosurgeons, we performed a PubMed search aimed to identify all papers published by a sample of neurosurgeons.
METHODS: Cross-sectional observational and regional study. We identified a sample of 183 neurosurgeons from Madrid and Castilla y León Autonomous Communities. The bibliometric information was gathered in March 2022 via PubMed free access website. For each author we registered the type of journal, total number of articles, order of appearance in the authors\' list, total IF, the proportion of articles signed as first or second author (Personal Authorship Quotient [PAQ]) and the percentage of IF attributable to those articles (Personal Impact Quotient [PIQ]).
RESULTS: A total of 3,592 articles from 183 authors were published in 412 different journals, of which only 9.9% were pure neurosurgical journals. Only 17 neurosurgeons (9,3%) had published at least one article as unique author. The average number of articles per neurosurgeon was 20 (median 9) of which 57.7% were published in neurosurgical journals, and 22,2% in
Neurocirugía (official publication of the SENEC). The average PAQ was 0.367 (median 0.364) and the average PIQ was 0.317 (median 0.251). Both proportions tended to decrease as the number of publications increased.
CONCLUSIONS: On average, Spanish neurosurgeons publish half of their articles in neurosurgical journals, appear as first or second author in one third of the cases, and the IF attributable to these papers comprise 25% of the total IF. The PAQ and PIQ provide bibliometric information that minimizes the enlarging effect on curriculum of massive co-authorship and allow comparisons among authors and different scientific fields.
