h指数,一种较SCI数量更合理的评估医学工作者学术影响力工具

摘要

The physicians and surgeons working in modern hospital should get achievement in the clinic,research,teaching,and prevention.In the past,scientific impact was assessed by the citation number of published papers in domestic and foreign journals,which obviously has many limitations.Hirsch JE,a physics professor from the United States proposed the h-index for the evaluation of the scientific impact of individual scientists in 2005.The h-index has been now been introduced in China.The applicability,limitations,and usage of h-index are discussed in this article.%现代医学工作者需要在临床医疗、科研、教育、预防等方面全面发展,学术影响力是评定全面发展医师学术水准的重要内容.过去常采用SCI期刊收录的论文数量和SCI期刊的影响因子作为主要的定量指标,此外SCI期刊收录的论文被引用次数和篇平均被引用次数也被使用.2005年美国Hirsch提出h指数这一指标,用于评估科学家本人的学术成就,其不仅可以弥补重论文数、不重视被引次数的不足,而且可以兼顾科学家的产出能力和研究质量.现在h指数已被应用于医学领域的学术影响力的评价.本文对h指数的计算方法、适用性、局限性进行述评.
