Bibliometric Analysis of Global Medical Insurance Research Trends
关于全球医疗保险研究态势的可视化分析

摘要

目的 本研究旨在通过对全球医疗保险相关文献进行可视化分析，了解其研究发展状况及研究热点，为未来相关研究提供参考。方法 我们使用计算机检索PubMed数据库，并运用带有Bibliometrix包的R代码（R版本4.2.3），对2010年至2024年间全球医疗保险研究的相关文献进行了数据分析。研究内容涵盖年度发文趋势、期刊分布、作者分布、词云分析、趋势主题、共现网络、主题地图、因子分析和合作网络等多个方面。结果 共筛选纳入与主题相关的文献905篇。全球“医疗保险”研究呈现出三个阶段：初始阶段（2010年）、巩固发展阶段（2011-2017年）和快速增长阶段（2018-2024年）。自2019年起，中国医疗保险研究迅速增加，中位数年份为2021年，至2023年研究依然活跃。截至2024年5月，中国已累计发表695篇文献，数量居首。在2020至2024年间，WU QUNHONG、TIAN GUOMEI和 SHAN LINGHAN是发文量最高的作者。此外，中国与美国、澳大利亚、加拿大等多个国家保持广泛合作关系。结论 全球医疗保险研究态势不断发展，未来将更加重视可持续性、健康公平与国际合作，以期构建更有效的全球医疗保障体系。深入研究将为政策制定者提供借鉴，优化我国医疗保险制度，最终提升全民健康水平。

Abstract

Objective This study aims to conduct a visual analysis of global medical insurance literature to understand the development status and research hotspots, providing a reference for future related research.
Methods We utilized computer searches in the PubMed database and employed R code with the Bibliometrix package (R version 4.2.3) to analyze literature related to global medical insurance research from 2010 to 2024. The analysis covered various aspects, including annual publication trends, most relevant sources, most relevant authors, word cloud , trend topics, co-occurrence network, thematic map, factorial Analysis, and collaboration network.
Results A total of 905 relevant articles were included in the analysis. Research on global "medical insurance" has exhibited three distinct phases: an initial phase (2010), a consolidation phase (2011-2017), and a rapid growth phase (2018-2024). Research on Chinese health insurance saw a significant increase starting in 2019, with a median publication year of 2021, and remains active through 2023. From 2020 to 2024, WU QUNHONG, TIAN GUOMEI, and SHAN LINGHAN emerged as the most prolific authors. Additionally, China maintains extensive collaborations with several countries, including the United States, Australia, and Canada.
Conclusion   The research landscape of global medical insurance is continuously evolving. Future research is expected to focus more on the sustainability of medical insurance, health equity, and international collaboration, providing more effective solutions for global health security.
