基于词频分析透视近十年国内PICC研究(1)
摘要：目的 关注我国PICC治疗研究现状和热点，为护理人员了解该领域发展态势，确定研究方向提供科学参考依据。方法 将“PICC”作为关键词，在万方数据库内进行检索，利用书目共现分析系统软件生成词篇矩阵和共现矩阵，通过SPSS21.0软件和Ucient6软件进行聚类分析和网络图绘制。结果 ①近十年PICC研究论文产出量大致可分为2个阶段。第一阶段为2008～2011年低水平期，第二阶段2012～2018年为后上升期;②共提取7218个关键词，词频不小于79次的关键词30个;③国内PICC研究主要关注点置管方法及并发症处理、临床护理实践效果、护理质量控制及风险及影响因素分析等几个方面。结论 國内静脉治疗研究趋于成熟，所涉及的方面较广泛，PICC院外护理管理专业化、专科护士规培训范化研究及带管患者回归家庭的相关研究较少见，日后研究可趋向这些内容。

Abstract：Objective To pay attention to the status quo and hotspots of PICC treatment research in China， and provide scientific reference for nursing staff to understand the development trend of this field and determine the research direction.Methods "PICC" was used as the key word to search in Wanfang database. The bibliographic analysis system software was used to generate the lexical matrix and co-occurrence matrix. The cluster analysis and network diagram were drawn by SPSS21.0 software and Ucient6 software.Results ①The output of PICC research papers in the past decade can be roughly divided into two stages. The first stage is the low level period from 2008 to 2011， and the second stage is the post-up period from 2012 to 2018;②A total of 7218 keywords were extracted， and 30 keywords with a word frequency of at least 79 times; ③domestic PICC studies focused on the method of placement and management of complications， clinical nursing practice effects， nursing quality control， risk and influencing factors analysis， etc. aspect.Conclusion Domestic venous treatment research is becoming more mature， and the aspects involved are more extensive. The specialization of PICC out-of-hospital nursing management， the research on the training of specialist nurses and the research on the return of families with patients are rare. Later research can tend to these contents.

经外周静脉置入心静脉导管(Peripherally Inserted Central Catheter，PICC)指由外周静脉(贵要静脉、肘正中静脉、头静脉)穿刺插管，使导管尖端位于上腔静脉的方法[1]。作为临床常用治疗手段，PICC已经从单一操作发展为涉及多学科、多层面的知识与技能临床意义及运用范围的临床技能。国内该项研究主要围绕临床实践、相关并发症处理及专科护士培养等展开。然而国内学者对于PICC现状多采用的文献综述方法[2，3]，并未有对PICC研究现状进行词频透视分析。词频分析法能够用于揭示某一学科的发展动态和研究进展，已经于多项学科领域中[4]。为系统地阐明静脉治疗研究热点及其联系，本项研究采用书目共现分析系统(bibliographic item co-occuren cematrix bulders，bicomb)提取PICC研究关键词后进行词频分析，具体研究内容及过程报道如下。, 百拇医药(曾频 雷佳芳 刘晓姝 晏萍兰)
