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.
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]).
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.
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.
评估科学文献的产出是一个复杂的问题，主要基于期刊的影响因子（IF）和 h 指数，后者量化了作者收到的引用数量。为了评估西班牙神经外科医生的文献产出和合著的影响力，我们进行了一项 PubMed 搜索，旨在确定对西班牙神经外科医生样本发表的所有论文。
横断面观察性和区域性研究。我们从马德里和卡斯蒂利亚-莱昂自治区确定了 183 名神经外科医生的样本。通过 PubMed 免费访问网站于 2022 年 3 月收集文献计量信息。对于每位作者，我们记录了期刊类型、文章总数、作者列表中的出现顺序、总 IF、以第一或第二作者签名的文章比例（个人作者比例 [PAQ]）以及归因于这些文章的 IF 百分比（个人影响比例 [PIQ]）。
来自 183 位作者的 3592 篇文章发表在 412 种不同的期刊上，其中只有 9.9%是纯神经外科期刊。只有 17 名神经外科医生（9.3%）以唯一作者身份发表过至少一篇文章。每位神经外科医生的平均文章数量为 20 篇（中位数为 9 篇），其中 57.7%发表在神经外科期刊上，22.2%发表在 Neurocirugía（SENEC 的官方出版物）上。平均 PAQ 为 0.367（中位数 0.364），平均 PIQ 为 0.317（中位数 0.251）。这两个比例随着出版物数量的增加而呈下降趋势。
平均而言，西班牙神经外科医生将其一半的文章发表在神经外科期刊上，三分之一的情况下作为第一或第二作者出现，这些论文的 IF 归因于这些论文占总 IF 的 25%。PAQ 和 PIQ 提供了文献计量信息，最大限度地减少了大规模合著对课程的扩大影响，并允许作者之间和不同科学领域之间进行比较。
