Results A total of 10,429 articles were included.The annual publication volume showed an overall upward trend, with the United States, Japan, and the United Kingdom ranking as the top three countries in total publications.A total of 30 high-frequency keywords were extracted, forming four clusters:research on the professional development of nursing assistants and the improvement of care quality; research on nursing assistants′ health interventions for key populations; research on nursing assistants in specific health domains; and research on the association between nursing assistants′ care quality and health outcomes. Conclusion Research related to nursing assistants abroad has formed hot spot clusters centered on the correlation between care quality and health outcomes, demonstrating a trend towards systematization and specialization.China can conduct in-depth empirical research tailored to its national conditions, considering demographic changes and the characteristics of its healthcare system, to promote the scienti-fic and sustainable development of the nursing assistant work force in China.
