Various bibliometric indices are now commonly used to assess academic productivity in medicine. Some evidence suggests that these measures are specific to subspecialty areas. The authors' goal was to measure the h index of academic pediatric neurosurgeons and compare it with previously reported results for academic neurosurgeons in general.
Programs with an Accreditation Council for Pediatric Neurosurgery Fellowships-approved fellowship were identified, and the h and g indices of each of their surgeons were calculated. These were correlated with academic rank and compared with published literature on academic neurosurgical departments.
Seventy-two pediatric neurosurgeons had a mean h index of 16.6 and a mean g index of 29.5. Both indices increased with progressive academic rank. The rank-specific mean index for academic pediatric neurosurgeons was similar to that of neurosurgeons from academic departments in general.
Overall, the authors conclude that the h index metric is a reasonable measure of academic productivity in the pediatric neurosurgery arena that provides a robust measure of an individual's contribution to the pediatric neurosurgery literature. Like its counterpart in neurosurgery in general, the h index for pediatric neurosurgeons correlates with institutional rank. The h index calculation also reveals the productivity of the pediatric neurosurgeons to be on par with the productivity of neurosurgeons in general.
各种文献计量指标目前常用于评估医学领域的学术产出。一些证据表明，这些指标因亚专业领域而异。作者的目标是衡量小儿神经外科医生的h指数，并将其与之前报道的普通神经外科医生的结果进行比较。
确定了获得小儿神经外科医师协会认可的奖学金项目，并计算了其每位外科医生的h指数和g指数。将这些指数与学术排名相关联，并与关于学术神经外科科室的已发表文献进行比较。
72名小儿神经外科医生的平均h指数为16.6，平均g指数为29.5。两个指数均随着学术排名的提升而增加。小儿神经外科医生按排名的平均指数与普通学术神经外科科室的医生相似。
总体而言，作者得出结论，h指数是衡量小儿神经外科领域学术产出的合理指标，能有力地衡量个人对小儿神经外科文献的贡献。与普通神经外科领域的对应指标一样，小儿神经外科医生的h指数与机构排名相关。h指数计算还表明，小儿神经外科医生的产出与普通神经外科医生相当。
