目的 利用文献计量学分析亚谵妄综合征(subsyndromal delirium，SSD)领域的研究现状、热点及前沿。方法 检索Web of Science核心合集数据库、知网、中国生物医学文献数据库中收录的SSD相关文献，检索时间为建库至2024年3月1日，采用Citespace软件对纳入文献进行分析。结果 共纳入英文文献213篇和中文文献68篇，国内外SSD发文量总体成平稳上升状态。SSD的发生率、危险因素、筛查与评估方法是目前的研究热点，SSD研究中护士占据主导地位，其中SSD的评估工具及危险因素预测是该领域研究的前沿。结论 SSD仍是当前研究热点，但针对各高危人群SSD防治措施的权威研究较少，今后可继续探索SSD的预见性护理措施，防止SSD进一步发展为谵妄。
Research Hotspots and Trends of Subsyndromal Delirium Based on CiteSpace:A Visual Analysis
Objective To analyze the current research status,hotspots and frontiers of research in the field of subsyndromal delirium(SSD)using bibliometric analysis.Methods The Web of Science Core Collec-tion,CNKI,and SinoMed databases were used as the sources to search for relevant literature on SSD from the establishment of the database to March 1,2024,and Citespace software was used to analyze the included literature.Results A total of 213 articles in English and 68 articles in Chinese were included,and the num-ber of domestic and international SSD publications showed a steady increase.Research on the incidence,risk factors,screening and assessment methods of SSD is a current research hotspot,and nurses dominate SSD research,with assessment tools and risk factor prediction of SSD being the forefront of research in this field.Conclusions SSD is still a current research hotspot,but there are fewer authoritative studies on pre-ventive and curative measures for SSD in various high-risk groups.In the future,we can continue to explore anticipatory nursing measures for SSD to prevent further development of SSD into delirium.
