国内外医疗器械相关性压力性损伤的文献计量学分析

Bibliometric analysis of medical device related pressure injuries at home and abroad

目的应用文献计量学方法,分析国内外医疗器械相关压力性损伤文献的研究热点。方法检索CNKI数据库和PubMed数据库相关文献,检索时限为建库至2019年7月,使用书目共现分析系统软件对检索获得的文献进行文献计量学分析,应用CiteSpace软件和gCLUTO软件对高频主题词进行可视化聚类分析。结果共纳入论文116篇,其中中文文献75篇(64.7%),英文文献41篇(35.3%)。国内外在该领域的研究均处于起步阶段,文献数量整体呈递增趋势,但国外的相关研究起步较早。提取75篇中文文献的主题词176个,最高频次为23次;提取41篇英文文献的主题词共63个,最高频次26次。中文文献聚类分为3组热点:医疗器械相关性压力性损伤的预防干预措施、发生原因及相关风险因素评估方法;英文文献聚类分为4组热点:医疗器械相关性压力性损伤具体发生部位、发生原因、医疗器械种类和预防方法。结论中英文文献在该领域研究的共同热点是其发生的原因和预防干预方法;中英文献主要是实验性研究和类实验研究,关注具体策略的实证应用;而中文文献主要是相关性研究和分析性研究,缺乏验证。因此,国内相关研究需进一步深入拓展。

Objective To analyze the research hotspots of medical device related pressure injuries at home and abroad with the method of bibliometric analysis.Methods Literatures were retrieved in the Chinese National Knowledge Infrastructure(CNKI)and PubMed from building database to July 2019.Bibliographic Items Co-occurrence Matrix Builder was used to carry out bibliometric analysis,and the CiteSpace and gCLUTO was used to visual clustering analysis on high-frequency keywords.Results A total of 116 literatures were included,75(64.7%)of them in Chinese and 41(35.3%)of them in English.Researches in this field at home and abroad were all in the early stage and number of literatures gradually increased,but researches abroad started early.Among 75 Chinese literatures,a total of 176 keywords were extracted with 23 for the highest frequency;among 41 English literatures,a total of 63 keywords were extracted with 26 for the highest frequency.Chinese literatures clusters included three hotspots,preventive intervention,causes and risk factors assessment methods of medical device related pressure injuries;English literatures clusters included four hotspots,occurrence site,causes of medical device related pressure injuries,types of medical equipment and preventive methods.Conclusions Researches in this field at home and abroad have hotspots of causes and preventive intervention in common.English literature focus on experimental study and quasi-experimental study,and pay attention to the empirical application of concrete strategy;Chinese literatures are mainly correlational study and analytic research,but lack of proving.Therefore,researches at home need to be expanded further.
