摘要:
目的 深入了解目前国内系统评价/Meta分析的研究概况,客观反映我国在该领域的科学能力和影响力。 方法 以ISI Web of Knowledge的Web of Science的核心合集为对象检索循证医学相关文献。采用文献计量的方法,分析循证医学相关文献的国家/地区分布,重点对来自中国的文献进行相关分析。以中国知网数据库为检索对象,检索循证医学相关的中文文献并进行简要分析。 结果 Web of Science数据库中检索得到71 476条结果: 发文量逐年递增,中国的发文量世界排名第三,国内发表杂志的影响因子偏低,四川大学、上海交通大学和南京医科大学等高校的发文量最大。中国循证医学杂志等收录了较多的中文的循证评价相关文章,四川大学华西医院等单位的发文量较大。 结论 循证医学目前仍是研究热点;北美和西欧地区在该领域具有领先优势;中国的发文量虽大,但影响力仍与国际前沿研究间存在一定差距。
Abstract:
Objective To better understand the current research of systematic review/meta analysis from China and to reflect scientific advances and influence on the world’s scientific community in the field. Methods The literatures were searched from Web of Science citation database (1986-2014), using the title of “meta analysis” or “systematic review”. The researching results were analyzed using bibliometric method concerning the article numbers, countries/districts, institutes, journal distribution, etc. The articles published by Chinese scientists were analyzed further. In addition, related literatures in China National Knowledge Infrastructure were also studied by bibliometric method. Results 71 476 literatures were recorded in Web of Science. The total number of publications and citations increased quickly during 1992-2014. China takes the third place in the world. Comparing with the publications of international peers, Chinese researchers articles have lower impact. Sichuan University, Shanghai Jiaotong University and Nanjing Medical University were the top three institutions that have the highest number of publications with highest quality in China. For Chinese papers, Chinese Journal of Evidence-based Medicine was the most important and popular. Condusion Evidence-based medicine attracted more and more attention and North America and Western Europe play a leading role in this field. The research in China has progressed rapidly, but still lagged behind its international peers.
