Acute exacerbations of chronic obstructive pulmonary disease COPD (AECOPD) can cause a significant decrease in patient lung function, and are the main reason for hospitalization and death of patients with COPD. This study aims to use bibliometric methods to analyze the characteristics of AECOPD related research in the past 10 years [2010-2020] and provide references for future research.
This study used subject terms to search AECOPD-related documents published in 2010-2020 in the Science Citation Index Expanded (SCI-E) database. The search terms were "AECOPD" or "acute exacerbation of chronic obstructive pulmonary disease." We use the CiteSpace software to analyze the target literature records. The analysis includes: the annual distribution of literature publications, the distribution of published literature sources (including countries, institutions, journals, and authors), and using keywords.
A total of 3,785 articles on AECOPD were published between 2010 and 2020, with 62,162 citations. Both the number of published documents and the number of citations has increased with time. The literature mainly comes from several developed countries, including European and North American countries, and the cooperation between institutions and authors in these countries is relatively close. The main journals are the top journals of respiratory specialty and the top comprehensive journals. The results of the keyword analysis show that the current research is on risk factors, biomarkers, and AECOPD management.
AECOPD research tends to focus on a precise diagnosis and treatment, and prevention of AECOPD in patients with COPD should be paid more attention.
慢性阻塞性肺疾病（COPD）急性加重（AECOPD）可导致患者肺功能显著下降，是 COPD 患者住院和死亡的主要原因。本研究旨在采用文献计量学方法分析过去 10 年（2010-2020 年）AECOPD 相关研究的特点，为今后的研究提供参考。
本研究采用主题词在科学引文索引扩展版（SCI-E）数据库中检索 2010-2020 年发表的 AECOPD 相关文献。检索词为“AECOPD”或“慢性阻塞性肺疾病急性加重”。使用 CiteSpace 软件对目标文献记录进行分析。分析包括：文献发表的年度分布、发表文献来源（包括国家、机构、期刊和作者）的分布，以及使用关键词。
2010-2020 年共发表了 3785 篇关于 AECOPD 的文章，引用次数为 62162 次。发表文献数量和引用次数均随时间增加而增加。文献主要来自几个发达国家，包括欧洲和北美国家，这些国家的机构和作者之间的合作较为紧密。主要期刊是呼吸专业的顶级期刊和综合期刊的顶级期刊。关键词分析的结果表明，目前的研究集中在风险因素、生物标志物和 AECOPD 的管理。
AECOPD 的研究倾向于注重精确诊断和治疗，应更加关注 COPD 患者 AECOPD 的预防。
