基于外文医学信息资源检索系统的经外周穿刺中心静脉导管研究现状文献计量学分析

Research status of peripherally inserted central catheter:a bibliometric analysis based on Foreign Medical Retrieval System

目的分析经外周穿刺中心静脉导管(peripherally inserted central catheter,PICC)研究发展趋势及研究热点,为我国血管通路领域临床护理和护理科研提供参考。方法检索外文医学信息资源检索系统内所有PICC相关文献,对文献数量、年份、语种、国家、高刊文期刊及影响因子、高产量作者以及高频主题词等,使用频数、构成比以及累计构成比进行描述性分析。检索时限为1806年—2018年11月22日。结果全球有586本期刊刊发PICC相关文献,共计刊文1550篇,其中393本期刊被美国《科学引文索引》收录;文献以英语为主,刊文数量最多的是美国;刊文量排名前16的作者共计刊文199篇,其中刊文量最多的前3位作者均有数量不等的合作论文;出现频率最高的前3个主题词是"导管,留置""导管插入术,中心静脉""中心静脉导管"。结论PICC已成为临床研究热点,尤其是2000年以后刊文量迅速增多,中国学者应提升英文水平,开展多中心合作研究,以提高中国PICC相关文献的刊发质量。

Objective To explore the trend and hotspots of research in the field of peripherally inserted central catheter(PICC),so as to provide a reference for clinical nursing and nursing research in the field of vascular access in China.Methods All PICC-related articles from 1806 to November 22 nd,2018 were searched in the Foreign Medical Retrieval System.The publication amount,year of publication,language,country,journals and impact factor,high-yield authors and high-frequent medical subject headings(MeSH)of the PICC-related articles were analyzed by using frequency,cumulative frequency,and constituent ratio.Results A total of 1550 articles were included.They were published in 586 journals,of which 393 were included in Science Citation Index.English was the dominant publication language,and the top high-yield country was the United States.The top 16 high-yield authors published 199 articles,the top 3 of whom all had published co-operative papers,ranging from 1 article to 19 articles.The top 3 high-frequent MeSHs were“Catheters,Indwelling”“Catheterization,Central Venous”“Central Venous Catheter”.Conclusions PICC has become a hotspot in clinical research,and the publication amount of relative literature has increased rapidly since2000.Chinese scholars should improve their English and carry out multi-center cooperative research to improve the quality of PICC-related literature.
