The Hirsch index is a novel index that combines the number of publications and citations in measuring the research output of researchers. We hypothesized that the h-index can be used to measure the academic success of an institution in a subject area (surgery) and compared this measure to previously published measures of ranking institutions.
We identified the top 10 research medical schools as designated by the United States News and World Report 2010. The h-index for an institution was obtained in 3-year periods for articles published in surgery. Independent rankings from the NIH and other web sites were then used to compare with our newly generated rankings.
The median h-index for institutions was 52.5 (46-54) for 2000-2002, 50 (44-52) for 2003-2005, 35.5 (33-40) for 2006-2008, and 15.5 (13-16) for 2009-2011. The percentage of self citations was the highest in publications from Harvard University (22.2%) and the lowest from Columbia University (10%) in the years 2009-11. Our ranking closely mirrored the United States News and World Report, and Harvard Medical School remains the top ranking in the field of surgery, although NIH funding-based ranking may suggest otherwise.
The institutional h-index appears to be a viable indicator for the measure of academic success of institutions in a subject area. Despite limitations, it yields objective data regarding the citations and number of articles published by an institution in a subject area and could be used to measure performance.
Hirsch 指数是一种新的指数，它将出版物数量和引文数量结合起来衡量研究人员的研究产出。我们假设 h 指数可用于衡量一个机构在某个学科领域（外科）的学术成功，并将这一衡量标准与之前发表的机构排名衡量标准进行比较。
我们确定了美国新闻与世界报道 2010 年指定的前 10 名研究医学院校。以机构在外科领域发表的文章为单位，以 3 年为周期获取机构的 h 指数。然后，使用来自 NIH 和其他网站的独立排名来与我们新生成的排名进行比较。
机构的中位数 h 指数为 2000-2002 年的 52.5（46-54），2003-2005 年的 50（44-52），2006-2008 年的 35.5（33-40），2009-2011 年的 15.5（13-16）。在 2009-11 年期间，哈佛大学出版物的自引率最高（22.2%），哥伦比亚大学最低（10%）。我们的排名与美国新闻与世界报道非常相似，哈佛大学医学院仍然是外科领域的顶级排名，尽管 NIH 基于资助的排名可能有所不同。
机构 h 指数似乎是衡量一个机构在某个学科领域学术成功的可行指标。尽管存在局限性，但它提供了有关机构在某个学科领域发表的引文和文章数量的客观数据，可用于衡量绩效。
