The Hirsch index (h-index) is a measure that evaluates both research volume and quality-taking into consideration both publications and citations of a single author. No prior work has evaluated academic productivity and contributions to the literature of adult total joint replacement surgeons. This study uses h-index to benchmark the academic impact and identify characteristics associated with productivity of faculty members at joint replacement fellowships.
Adult reconstruction fellowship programs were obtained via the American Association of Hip and Knee Surgeons website. Via the San Francisco match and program-specific websites, program characteristics (Accreditation Council for Graduate Medical Education approval, academic affiliation, region, number of fellows, fellow research requirement), associated faculty members, and faculty-specific characteristics (gender, academic title, formal fellowship training, years in practice) were obtained. H-index and total faculty publications served as primary outcome measures. Multivariable linear regression determined statistical significance.
Sixty-six adult total joint reconstruction fellowship programs were identified: 30% were Accreditation Council for Graduate Medical Education approved and 73% had an academic affiliation. At these institutions, 375 adult reconstruction surgeons were identified; 98.1% were men and 85.3% had formal arthroplasty fellowship training. Average number of publications per faculty member was 50.1 (standard deviation 76.8; range 0-588); mean h-index was 12.8 (standard deviation 13.8; range 0-67). Number of fellows, faculty academic title, years in practice, and formal fellowship training had a significant ( < .05) positive correlation with both h-index and total publications.
The statistical overview presented in this work can help total joint surgeons quantitatively benchmark their academic performance against that of their peers.
赫希指数（h指数）是一种考量单一作者的出版物和引用情况，对研究数量和质量进行评估的指标。此前尚无研究评估成人全关节置换外科医生的学术生产力及其对文献的贡献。本研究使用h指数来衡量学术影响力，并确定与关节置换 fellowship 项目中教员生产力相关的特征。
通过美国髋膝关节外科医生协会网站获取成人重建 fellowship 项目。通过旧金山匹配系统和特定项目网站，获取项目特征（毕业后医学教育认证委员会批准情况、学术隶属关系、地区、研究员数量、研究员研究要求）、相关教员以及教员特定特征（性别、学术头衔、正规 fellowship 培训、执业年限）。h指数和教员总出版物数量作为主要结局指标。多变量线性回归确定统计学意义。
共识别出66个成人全关节重建 fellowship 项目：30% 获得毕业后医学教育认证委员会批准，73% 有学术隶属关系。在这些机构中，共识别出375名成人重建外科医生；98.1% 为男性，85.3% 接受过正规关节置换 fellowship 培训。每位教员的平均出版物数量为50.1（标准差76.8；范围0 - 588）；平均h指数为12.8（标准差13.8；范围0 - 67）。研究员数量、教员学术头衔、执业年限和正规 fellowship 培训与h指数和总出版物数量均呈显著（P < .05）正相关。
本研究呈现的统计概述可帮助全关节外科医生将其学术表现与同行进行定量比较。
