A scholar's h-index is defined as the number of h papers published, each of which has been cited at least h times. We hypothesized that the h-index strongly correlates with the academic rank of surgical oncologists.
We utilized the National Cancer Institute (NCI) website to identify NCI-designated Comprehensive Cancer Centers (CCC) and Doximity to identify the 50 highest-ranked general surgery residency programs with surgical oncology divisions. Demographic data of respective academic surgical oncologists were collected from departmental websites and Grantome. Bibliometric data were obtained from Web of Science.
We identified 544 surgical oncologists from 64 programs. Increased h-index was associated with academic rank (p < 0.001), male gender (p < 0.001), number of National Institutes of Health (NIH) grants (p < 0.001), and affiliation with an NCI CCC (p = 0.018) but not number of additional degrees (p = 0.661) or Doximity ranking (p = 0.102). H-index was a stronger predictor of academic rank (r = 0.648) than total publications (r = 0.585) or citations (r = 0.450).
This is the first report to assess the h-index within academic surgical oncology. H-index is a bibliometric predictor of academic rank that correlates with NIH grant funding and NCI CCC affiliation. We also highlight a previously unexpected and unappreciated gender disparity in the academic productivity of US surgical oncologists. When academic rank was accounted for, female surgical oncologists had lower h-indices compared with their male colleagues. Evaluation of the etiologies of this gender disparity is needed to address barriers to academic productivity faced by female surgical oncologists as they progress through their careers.
学者的 h 指数定义为已发表的 h 篇论文数量，每篇论文的引用次数至少为 h 次。我们假设 h 指数与外科肿瘤学家的学术排名密切相关。
我们利用美国国家癌症研究所 (NCI) 网站确定了 NCI 指定的综合癌症中心 (CCC)，并利用 Doximity 确定了 50 个排名最高的拥有外科肿瘤学部门的普通外科住院医师培训项目。从系网站和 Grantome 收集了各自学术外科肿瘤学家的人口统计学数据。从 Web of Science 获得了文献计量数据。
我们从 64 个项目中确定了 544 名外科肿瘤学家。h 指数的增加与学术排名相关（p<0.001）、男性性别（p<0.001）、美国国立卫生研究院 (NIH) 拨款数量（p<0.001）和 NCI CCC 的隶属关系（p=0.018）相关，但与额外学位数量（p=0.661）或 Doximity 排名（p=0.102）无关。h 指数是学术排名的一个更强的预测指标（r=0.648），而不是总出版物（r=0.585）或引用次数（r=0.450）。
这是第一篇评估学术外科肿瘤学中 h 指数的报告。h 指数是学术排名的文献计量预测指标，与 NIH 拨款资助和 NCI CCC 隶属关系相关。我们还强调了美国外科肿瘤学家学术生产力中以前未被注意到的性别差异。当考虑到学术排名时，与男性同事相比，女性外科肿瘤学家的 h 指数较低。需要评估这种性别差异的原因，以解决女性外科肿瘤学家在职业生涯中面临的学术生产力障碍。
