Scientometric studies are one of the most important and useful tools to assess the research performance and knowledge impact of researchers. The aim of this study was to map out the scientific performance of the Iranian medical academics with respect to a detailed range of scientometric indicators.
Using scientometric approach, individual and scientific performance data of medical academic staff were extracted from the Iranian Scientometric Information Database (ISID). Total number of publications, total number of citations, citation per paper, h-index, international collaboration, self-citation, SJR decile, i10-Index, Quartile distribution were the studied scientometric variables. Out of the registered 19,023 academic staff, 746 were included in the study through simple random sampling method using random sample extraction function in STATA. Data were analyzed using STATA 14 statistical software package.
Most of the included academicians were men (60%). A total of 13,682 articles were published by them until 2018, being cited 114,928 times with a mean of 5.77 citation per paper. H-index median was three and about 90% of the staff had an H-index below 10. Number of published papers, cite per paper and H-index metrics were significantly different with respect to gender, academic position/degree, and general field of study (p < 0.05). About 2.5% of published articles were contributed through international collaboration. The scientometric performance of academic staff was highly diverse with respect to the employing institution and its national classification group (type 1, 2, 3).
Nevertheless to the great scientific production of medical academics, individual and institutional characteristics were identified as effective variables in academics research performance and should be considered in their assessment. Academicians affiliated with type 2 and 3 universities (based on national ranking of medical universities) had weaker research performance compared to those affiliated with type 1 universities. However, low rate of international research collaborations was a common challenge in medical universities.
科学计量学研究是评估研究人员研究绩效和知识影响力的最重要和最有用的工具之一。本研究的目的是利用一系列详细的科学计量指标来绘制伊朗医学学术人员的科学表现图谱。
采用科学计量学方法，从伊朗科学计量信息数据库（ISID）中提取医学学术人员的个人和科学绩效数据。研究的科学计量变量包括总发文量、总被引频次、篇均被引、h 指数、国际合作、自引、SJR 百分位、i10 指数、四分位分布。在注册的 19023 名学术人员中，通过 STATA 中的随机样本提取功能，采用简单随机抽样方法抽取 746 名学术人员进行研究。使用 STATA 14 统计软件包对数据进行分析。
纳入的学术人员中，男性（60%）居多。截至 2018 年，他们共发表了 13682 篇文章，被引 114928 次，篇均被引 5.77 次。h 指数中位数为 3，约 90%的人员 h 指数低于 10。发文量、篇均被引和 h 指数指标在性别、学术地位/学位和一般学科领域方面存在显著差异（p<0.05）。通过国际合作发表的文章约占 2.5%。学术人员的科学计量表现因所属机构及其国家分类组（1 型、2 型、3 型）而异，呈现出高度的多样性。
尽管医学学术人员的科研产出巨大，但个体和机构特征被确定为影响学术人员研究绩效的有效变量，在评估中应予以考虑。与 1 型大学相比，隶属于 2 型和 3 型大学（基于医学大学的国家排名）的学术人员的研究绩效较弱。然而，国际合作研究的低比例是医学大学面临的一个共同挑战。
