卒中相关性肺炎危险因素的文献计量学分析

目的：分析卒中相关性肺炎危险因素的研究现状和趋势，为相关研究提供借鉴和参考。方法：基于Web of Science核心合集，对卒中相关性肺炎危险因素的研究文献进行综合分析，运用VOSviewer软件对研究机构、核心期刊、核心作者等进行可视化分析。结果：共检索到142篇符合标准的文献，涉及31个国家，分布在61种期刊上。当前卒中相关性肺炎危险因素研究形成了以德国夏里特医院为中心的主要合作网络，我国的核心领军机构是北京天坛医院。提取危险因素进行词频分析后发现，NIHSS评分、年龄及吞咽障碍是卒中相关性肺炎的主要危险因素，而生物标记物是目前的研究热点。结论：我国在卒中相关性肺炎危险因素的研究方面比较深入，已基于我国人群构建了预测量表，但高质量的研究集中在单一机构，区域间跨机构合作仍待加强。

Bibliometric analysis of risk factors for stroke-associated pneumonia

Objective To analyze the risk factors for stroke-associated pneumonia and its trend in order to provide experiences and reference for research in relation with stroke-associated pneumonia. Methods The papers on risk factors for stroke-associated pneumonia were comprehensively analyzed on the basis of Web of Science Core Collection. The research institutions, core journals, and core authors that published the papers on risk factors for stroke-associated pneumonia were analyzed by visualization analysis with VOSviewer software. Results One hundred and forty-two papers on risk factors for stroke-associated pneumonia confirming to the inclusion criteria in this paper were retrieved from the Web of Science core database, which were published in 61 journals by 31 countries. The research on risk factors for stroke-associated pneumonia has formed a major collaboration network with the Charitè Hospital in Germany as its center. The domestic core leading research institution on risk factors for stroke-associated pneumonia is Beijing Tiantan Hospital. The word frequency analysis of risk factors for stroke-associated pneumonia showed that NIHSS score, age and dysphagia were the major risk factors for stroke-associated pneumonia while biomarkers were the current hot spot in research on risk factors for stroke-associated pneumonia. Conclusion The research on risk factors for stroke-associated pneumonia in our country is going in depth, and corresponding prediction models of stroke-associated pneumonia have been established. However, the high academic level research is centralized in single research institution and trans-regional and trans-institutional collaboration in research on stroke-associated pneumonia needs to be strengthened.
