目的 分析美国国家科学基金会中护理-信息-工程学相关科研项目资助情况，为促进我国护理-信息-工程学科发展提供参考。 方法 使用Python语言的网络爬虫和隐含狄利克雷分布（latent Dirichlet allocation,LDA）模型对美国国家科学基金会中护理-信息-工程学相关的项目数据进行采集、预处理和分析。 结果 本研究共纳入265个相关科研项目，时间跨度为1988年至2023年，立项数量和资助金额整体呈上升趋势。纳入项目共包含2153个词，基于LDA模型分为6个主题，分别为智能技术在患者安全管理中的研究、面向患者的护理大数据系统的研发、护士健康及辅助决策工具的研发、虚拟现实技术在护理教育中的应用、传感器和无线辅助设备的研发和机器人在医院工作流程中的应用。 结论 大数据和信息化时代让信息学和工程学融入到护理学科的建设当中，研究者可结合国情继续深入探索我国护理-信息-工程学的发展前景。

Objective To analyze the nursing-information-engineering-related scientific research programs funded by the National Science Foundation of the United States,and to provide a reference for the research in China. Methods The Python web crawler and machine learning technology were used to collect,pre-process,and analyze the data of the nursing-information-engineering-related programs funded by the National Science Foundation of the United States. Results A total of 265 related scientific research programs were included in the study,covering the period from 1988 to 2023.The overall number of projects and the funding amount showed an increasing trend.The total number of words included in the included project was 2 153,which was divided into 6 topics based on the LDA model,including research on intelligent technology in patient safety management,research and development of patient-oriented nursing big data system,research and development of nurse health and auxiliary decision-making tools,application of virtual reality technology in nursing education,research and development of sensors and wireless auxiliary devices,and application of robots in hospital workflow. Conclusions With the background of big data and informatization,informatics and engineering have been integrated into the construction of nursing sciences.The researchers can continue to explore the development prospect of nursing-information-engineering in China according to China’s national conditions.
