Bibliometrics are the methods used to quantitatively analyze scientific literature. In this study, bibliometrics were used to quantify the scientific output of neurosurgical departments throughout Great Britain and Ireland.
A list of neurosurgical departments was obtained from the Society of British Neurological Surgeons website. Individual departments were contacted for an up-to-date list of consultant (attending) neurosurgeons practicing in these departments. Scopus was used to determine the h-index and m-quotient for each neurosurgeon. Indices were measured by surgeon and by departmental mean and total. Additional information was collected about the surgeon's sex, title, listed superspecialties, higher research degrees, and year of medical qualification.
Data were analyzed for 315 neurosurgeons (25 female). The median h-index and m-quotient were 6.00 and 0.41, respectively. These were significantly higher for professors (h-index 21.50; m-quotient 0.71) and for those with an additional MD or PhD (11.0; 0.57). There was no significant difference in h-index, m-quotient, or higher research degrees between the sexes. However, none of the 16 British neurosurgery professors were female. Neurosurgeons who specialized in functional/epilepsy surgery ranked highest in terms of publication productivity. The 5 top-scoring departments were those in Addenbrooke's Hospital, Cambridge; St. George's Hospital, London; Great Ormond Street Hospital, London; National Hospital for Neurology and Neurosurgery, Queen Square, London; and John Radcliffe Hospital, Oxford.
The h-index is a useful bibliometric marker, particularly when comparing between studies and individuals. The m-quotient reduces bias toward established researchers. British academic neurosurgeons face considerable challenges, and women remain underrepresented in both clinical and academic neurosurgery in Britain and Ireland.
文献计量学是用于对科学文献进行定量分析的方法。在本研究中，文献计量学被用于量化英国和爱尔兰各地神经外科科室的科研产出。
从英国神经外科医师协会网站获取神经外科科室名单。与各个科室联系以获取在这些科室执业的顾问（主治）神经外科医生的最新名单。使用Scopus确定每位神经外科医生的h指数和m商数。指数按外科医生以及科室均值和总数进行测量。收集了关于外科医生的性别、职称、列出的亚专业、更高的研究学位以及医学资格年份的其他信息。
对315名神经外科医生（25名女性）的数据进行了分析。h指数和m商数的中位数分别为6.00和0.41。教授（h指数21.50；m商数0.71）以及拥有额外医学博士或哲学博士学位的人（11.0；0.57）的这些指数显著更高。性别之间在h指数、m商数或更高研究学位方面没有显著差异。然而，16名英国神经外科教授中没有女性。专门从事功能/癫痫手术的神经外科医生在发表产出方面排名最高。得分最高的5个科室是剑桥阿登布鲁克医院、伦敦圣乔治医院、伦敦大奥蒙德街医院、伦敦女王广场国立神经病学和神经外科医院以及牛津约翰·拉德克利夫医院。
h指数是一个有用的文献计量指标，特别是在不同研究和个体之间进行比较时。m商数减少了对知名研究人员的偏倚。英国学术神经外科医生面临相当大的挑战，并且在英国和爱尔兰的临床和学术神经外科领域，女性的代表性仍然不足。
