背景：h指数是一种常用的衡量研究人员发表绩效的指标。然而，在医学信息学等多学科领域，解释h指数是一个挑战，因为研究人员往往拥有不同的专业，从临床领域到计算机科学、基础科学和社会科学，每个领域都有不同的发表绩效概况。目的：构建医学信息学研究人员h指数的参考标准。方法：选取2006-2011年间在医学信息学2大顶级期刊（以影响因子确定）发表文章的作者为样本，利用Scopus数据库计算其h指数。通过计算百分位数，创建了一个6级基准（类似于美国国家科学基金会使用的方案）和一个10级基准。结果：这两个基准可以根据同行的表现将医学信息学研究人员置于有序的类别中。一项验证工作将基准水平映射到美国医学信息学学术教师的行列。这个由10个等级组成的基准更好地追踪了学术排名（没有联系），因此更适合实际应用。结论：我们的10级基准为利用h指数评价和比较医学信息学研究人员与同行的发表绩效提供了客观的依据。[J] .医学互联网研究，2012;14(5):e144) doi: 10.2196/jmir.2177
Background: The h-index is a commonly used metric for evaluating the publication performance of researchers. However, in a multidisciplinary field such as medical informatics, interpreting the h-index is a challenge because researchers tend to have diverse home disciplines, ranging from clinical areas to computer science, basic science, and the social sciences, each with different publication performance profiles.Objective: To construct a reference standard for interpreting the h-index of medical informatics researchers based on the performance of their peers.Methods: Using a sample of authors with articles published over the 5-year period 2006-2011 in the 2 top journals in medical informatics (as determined by impact factor), we computed their h-index using the Scopus database. Percentiles were computed to create a 6-level benchmark, similar in scheme to one used by the US National Science Foundation, and a 10-level benchmark.Results: The 2 benchmarks can be used to place medical informatics researchers in an ordered category based on the performance of their peers. A validation exercise mapped the benchmark levels to the ranks of medical informatics academic faculty in the United States. The 10-level benchmark tracked academic rank better (with no ties) and is therefore more suitable for practical use.Conclusions: Our 10-level benchmark provides an objective basis to evaluate and compare the publication performance of medical informatics researchers with that of their peers using the h-index.
