The application of bibliometric techniques to academic neurosurgery has been the focus of several recent publications. The authors provide here a detailed analysis of all active pediatric neurosurgeons in North America and their respective departments.
Using Scopus and Google Scholar, a bibliometric profile for every known active pediatric neurosurgeon in North America was created using the following citation metrics: h-, contemporary h-, g-, and e-indices and the m-quotient. Various subgroups were compared. Departmental productivity from 2008 through 2013 was measured, and departments were ranked on the basis of cumulative h- and e-indices and the total number of publications and citations. Lorenz curves were created, and Gini coefficients were calculated for all departments with 4 or more members.
Three hundred twelve pediatric neurosurgeons (260 male, 52 female) were included for analysis. For the entire group, the median h-index, m-quotient, contemporary h-, g-, and e-indices, and the corrected g- and e-indices were 10, 0.59, 7, 18, 17, 1.14, and 1.01, respectively; the range for each index varied widely. Academic pediatric neurosurgeons associated with fellowship programs (compared with unassociated neurosurgeons), academic practitioners (compared with private practitioners), and men (compared with women) had superior measurements. There was no significant difference between American and Canadian pediatric neurosurgeons. The mean Gini coefficient for publications was 0.45 (range 0.18-0.70) and for citations was 0.53 (range 0.25-0.80).
This study represents the most exhaustive evaluation of academic productivity for pediatric neurosurgeons in North America to date. These results should serve as benchmarks for future studies.
文献计量学技术在学术神经外科中的应用一直是近期几篇出版物的焦点。作者在此对北美所有活跃的儿科神经外科医生及其各自所在科室进行了详细分析。
利用Scopus和谷歌学术，通过以下引用指标为北美每一位已知的活跃儿科神经外科医生创建文献计量学概况：h指数、当代h指数、g指数、e指数和m商数。对各个亚组进行了比较。测量了2008年至2013年各科室的生产力，并根据累积h指数和e指数、出版物总数和引用次数对科室进行排名。绘制了洛伦兹曲线，并为所有有4名或更多成员的科室计算了基尼系数。
纳入分析的儿科神经外科医生有312名（男性260名，女性52名）。对于整个群体，h指数中位数、m商数、当代h指数、g指数、e指数以及校正后的g指数和e指数分别为10、0.59、7、18、17以及1.14和1.01；每个指数的范围差异很大。与 fellowship 项目相关的学术儿科神经外科医生（与无关联的神经外科医生相比）、学术从业者（与私人从业者相比）以及男性（与女性相比）的测量结果更优。美国和加拿大的儿科神经外科医生之间没有显著差异。出版物的平均基尼系数为0.45（范围0.18 - 0.70），引用的平均基尼系数为0.53（范围0.25 - 0.80）。
本研究是迄今为止对北美儿科神经外科医生学术生产力最详尽的评估。这些结果应作为未来研究的基准。
