The subspecialized, clinically complex nature of neurosurgery should not result in marginalization or under-representation of neurosurgical scientific output. This study aims to provide an overview of the trends of neurosurgical publications in high-impact medical journals during the past 3 decades.
An electronic database search was performed to identify all articles affiliated with neurosurgery departments published in 10 highly regarded medical journals. The trend of the proportion of neurosurgical publications to total publications in these journals was examined over time. Subgroup analyses on the basis of location, setting, domain, grant source, and topic of the articles were performed.
Overall, 2090 neurosurgical publications were identified in the selected journals, comprising 0.26% of those journals' publications. The proportion of neurosurgical publications to total publications in these journals increased over time, from 0.03% before 1991 to 0.35% after 2020. Most studies were single-center (82.7%), clinical (52.4%), and primary research (89%). The United States (40.1%), China (12.4%) and the United Kingdom (7.1%) had the greatest number of neurosurgical publications among those analyzed. The share of clinical neurosurgical articles increased over time compared with basic and translational articles (P = 0.01). Among neurosurgical subspecialties, neuro-oncology (60.1%), vascular (19.0%), and general (7.0%) had the greatest number of publications identified, with substantial increases in vascular publications over time. The mean number of citations per year received by neurosurgical articles has increased over time, from 1.65 (before 1991) to 4.12 (2010-2020).
Neurosurgery's proportion of high-impact journal publications has increased over time.
神经外科的专业、临床复杂性不应导致神经外科学术产出边缘化或代表性不足。本研究旨在概述过去 30 年来高影响力医学期刊中神经外科出版物的趋势。
通过电子数据库搜索，确定了发表在 10 种知名医学期刊上的所有与神经外科系相关的文章。考察了这些期刊上神经外科出版物占总出版物的比例随时间的变化趋势。还进行了基于位置、环境、领域、资助来源和文章主题的亚组分析。
在选定的期刊中，共发现 2090 篇神经外科出版物，占这些期刊出版物的 0.26%。这些期刊上神经外科出版物占总出版物的比例随时间的推移而增加，从 1991 年之前的 0.03%增加到 2020 年的 0.35%。大多数研究为单中心（82.7%）、临床（52.4%）和原始研究（89%）。在分析中，美国（40.1%）、中国（12.4%）和英国（7.1%）的神经外科出版物数量最多。与基础和转化文章相比，临床神经外科文章的比例随时间的推移而增加（P=0.01）。在神经外科亚专业中，神经肿瘤学（60.1%）、血管（19.0%）和一般（7.0%）的出版物数量最多，血管出版物的数量随时间的推移而显著增加。神经外科文章每年收到的平均引用次数随时间的推移而增加，从 1991 年前的 1.65 次增加到 2010-2020 年的 4.12 次。
