With the aging population increasing dramatically and the high cost of long-term care (LTC), long-term care insurance (LTCI) has expanded rapidly across the world. This review aims to summarize the status quo, evolution trends, and new frontiers of global LTCI research between 1984 and 2021 through a comprehensive retrospective analysis. A total of 1568 articles retrieved from the Web of Science Core Collection database were systematically analyzed using CiteSpace visualization software (CiteSpace 5.8. R2, developed by Dr. Chaomei Chen at Drexel University (Philadelphia, PA, USA)). The overall characteristics analysis showed that LTCI is an emerging research field in a rapid development stage-nearly 50% of articles were published in the past five years. The most productive LTCI research institutions and authors are located primarily in Japan and the USA. A rigorous analysis based on a dual perspective of references and keywords was applied to reveal that common LTCI hot topics include disability in the elderly, LTC financing, demand for and supply of LTCI, and LTCI systems. In addition, LTCI research trends have shifted from the supply side to the demand side, and from basic studies to practical applications. The new research frontiers are frailty in the elderly, demand for LTCI, and LTCI systems. These findings can provide help and reference for public health practitioners and researchers, as well as help with the sustainable development of LTCI research.
随着人口老龄化的急剧增加和长期护理（LTC）成本的高昂，长期护理保险（LTCI）在全球范围内迅速扩张。本综述旨在通过全面的回顾性分析，总结 1984 年至 2021 年间全球 LTCI 研究的现状、演变趋势和新前沿。从 Web of Science Core Collection 数据库中检索到的 1568 篇文章通过 CiteSpace 可视化软件（CiteSpace 5.8. R2，由美国宾夕法尼亚州费城德雷克塞尔大学的 Chaomei Chen 博士开发）进行了系统分析。总体特征分析表明，LTCI 是一个处于快速发展阶段的新兴研究领域——近 50%的文章是在过去五年发表的。LTCI 最具生产力的研究机构和作者主要位于日本和美国。基于参考文献和关键词的双重视角进行了严格的分析，揭示了常见的 LTCI 热点话题包括老年人残疾、LTC 融资、LTCI 的需求和供应以及 LTCI 系统。此外，LTCI 研究趋势已经从供应方转向需求方，从基础研究转向实际应用。新的研究前沿是老年人的脆弱性、LTCI 的需求以及 LTCI 系统。这些发现可以为公共卫生从业者和研究人员提供帮助和参考，有助于 LTCI 研究的可持续发展。
