基于中国生物医学文献数据库的坠积性肺炎研究热点的可视化分析

Visual analysis on research hotspots of hypostatic pneumonia based on the sinomed database

目的 通过剖析近10年坠积性肺炎有关文献的发展趋势和研究热点,为我国进一步坠积性肺炎的研究进展提供借鉴。方法 通过检索中国生物医学文献数据库收录的2012—2021年发表的坠积性肺炎相关文献,并利用BICOMS-2分析软件进行提取和整合主要信息,并形成共现矩阵,使用Ucinet 6.0软件NetDraw绘制社会网络图,采用Gcluto软件对主题词展开了聚类分析,并形成了可视化曲面图和可视化矩阵图。结果 共纳入530篇中文文献,来源于210种期刊,被北大中文核心期刊收录的文章占比不到5%;提取69个高频主题词,其中词频≥20次的有“护理”“脑卒中”“护理干预”“并发症”“长期卧床”和“老年患者”;根据实际的聚类分析结果显示目前坠积性肺炎有4大类研究热点主题,集中在预防及治疗措施、康复效果和生活质量、气管切开、脑血管疾病及骨折术后并发症。结论 近10年我国坠积性肺炎研究关注人群为老年患者,研究类型主要是干预性研究,研究重点是坠积性肺炎的预防、护理及治疗;但我国坠积性肺炎相关研究领域高质量研究文献较少,建议研究者今后应积极合作并开展高质量且大规模的相关研究,进一步加大对坠积性肺炎的持续关注。

Objective To provide reference for the future studies on hypostatic pneumonia in China by analyzing the research trends and hotspots related to the literature of hypostatic pneumonia in recent ten years.Methods The literature related to hypostatic pneumonia published from 2012 to2021 was searched in SinoMed database.The BICOMS-2 analysis software was used to extract and sort out the main information and generate co-occurrence matrix.NetDraw from Ucinet 6.0 software was used to draw the social network diagram.Gcluto software was used to perform cluster analysis on the subject terms,and generate visual surface graph and visual matrix graph.Results A total of530 Chinese articles were included,published in 210 kinds of journals,and less than 5% of the articles were included in Peking University Chinese core journals.Totally,69 high-frequency subject words were extracted,among which the words frequency ≥20 times were “nursing”,“stroke”,“nursing intervention”,“complications”,“long-term bed rest”,and“elderly patients”.According to the actual cluster analysis results,there were four categories of research hotspots of hypostatic pneumonia,focusing on prevention and treatment measures,rehabilitation effect and quality of life,tracheotomy,cerebrovascular diseases and postoperative complications of fracture.Conclusions In the past ten years,the research on hypostatic pneumonia in China mainly focused on elderly patients,and the research type was mainly interventional research,with the focus on the prevention,nursing and treatment of hypostatic pneumonia.However,there were few high-quality studies in the field of hypostatic pneumonia in China.It is suggested that researchers should cooperate actively and carry out high-quality and large-scale related studies in the future to further increase the continuous attention to hypostatic pneumonia.
