Objective measures of research productivity depend on how frequently a publication is cited. Metrics such as the Hirsch index (h-index; total number of publications h that have at least h citations) allow for an objective measurement of the scientific impact of an author's publications.
The purpose of this study was to assess and compare the h-index among aesthetic plastic surgery fellowship directors to that of fellowship directors in craniofacial surgery and microsurgery.
We conducted a cross-sectional study of all fellowship directors in aesthetic surgery, craniofacial surgery, and microsurgery in the United States and Canada. The gathered data were categorized as bibliometric (h-index, i10-index, total number of publications, total number of citations, maximum citations for a single work, and number of self-citations) and demographic (gender, training background). Descriptive statistics were computed.
The sample was composed of 30 aesthetic surgeons (93% male), 33 craniofacial surgeons (97% male), and 32 microsurgeons (94% male). The mean h-index was 13.7 for aesthetics, 16.9 for craniofacial, and 12.4 for microsurgery. There were no significant differences for any of the bibliometric measures between the three subspecialties, despite the fact that academic rank and years in practice were significantly different.
As measured by the h-index, there is a high level of academic productivity among fellowship directors, regardless of subspecialty area. Unlike other plastic surgery subspecialties however, the h-index of aesthetic plastic surgeons is not correlated to academic rank, revealing a discrepancy between perceptions of aesthetic plastic surgery and its actual academic impact.
研究产出的客观衡量标准取决于出版物被引用的频率。诸如赫希指数(h指数;被引用次数至少为h次的h篇出版物的总数)等指标能够客观衡量作者出版物的科学影响力。
本研究旨在评估并比较美容整形外科 fellowship 主任与颅面外科和显微外科 fellowship 主任之间的h指数。
我们对美国和加拿大所有美容外科、颅面外科和显微外科的 fellowship 主任进行了一项横断面研究。收集的数据分为文献计量学数据(h指数、i10指数、出版物总数、被引用总数、单篇作品的最高被引用次数以及自引次数)和人口统计学数据(性别、培训背景)。计算描述性统计量。
样本包括30名美容外科医生(93%为男性)、33名颅面外科医生(97%为男性)和32名显微外科医生(94%为男性)。美容外科的平均h指数为13.7,颅面外科为16.9,显微外科为12.4。尽管学术职称和从业年限存在显著差异,但这三个亚专业在任何文献计量学指标上均无显著差异。
以h指数衡量,无论亚专业领域如何,fellowship 主任的学术产出水平都很高。然而,与其他整形外科亚专业不同的是,美容整形外科医生的h指数与学术职称无关,这揭示了对美容整形外科的认知与其实际学术影响力之间的差异。
