Objective To use bibliometrics to identify research hotspots and emerging trends in the use of artificial intelligence (AI) in healthcare-associated infections (HAI), as well as to offer a resource for more relevant research. Methods The literature on AI and HAI from the Science Citation Index Expanded database of the Web of Science Core Collection was retrieved through computer searches, covering the period from January 1, 1994, to January 22, 2024. VOSviewer (v1.6.19) and CiteSpace (v6.1. R6) software were utilized for bibliometric analysis, creating knowledge maps that include research cooperation networks and keyword analysis. Results A total of 305 documents were included, and both the number of early publications and the frequency of citations were at a very low level for a long time before showing an annual increase trend after 2018. The United States had the most published documents among the 50 countries/regions from where they were sourced. Harvard University was the scientific research institution with the most publications, while Professor Evans HL of the Medical University of South Carolina was the scholar with the most publications. Research on AI in the field of HAI primarily focused on three aspects: AI algorithms and technologies, monitoring and prediction of HAI, and the accuracy of HAI diagnosis and prediction. These findings were based on keyword co-occurrence and clustering analysis. Conclusions A new phase of AI research in the subject of HAI has begun. More in-depth research can be done in the future for the hot direction, as there is still a gap between China’s academic accomplishments in this subject and the advanced level of the world.
ObjectiveTo systematically map the research landscape, hotspots, and evolutionary trends of Chinese-language literature on value-based healthcare (VBHC) in China, and to provide evidence for advancing localized VBHC research and practice. Methods VBHC-related publications published between January 1, 2006 and August 30, 2024 were retrieved from the China National Knowledge Infrastructure, Wanfang Data, and VIP database. CiteSpace was used for visualized bibliometric analyses, including co-authorship, institutional collaboration, keyword co-occurrence, clustering, burst detection, and timeline mapping. Results A total of 237 articles were included. Since 2017, VBHC-related publications in China have increased markedly. Collaboration networks among institutions and authors showed low density, indicating relatively weak and fragmented cooperation. High-frequency keywords included “value co-creation” “public hospitals” and “value orientation”. Burst analysis identified “healthcare costs” “value co-creation” and “medical insurance payment” as major recent research focuses. The timeline map suggested three stages in the evolution of VBHC research: initial exploration, emerging development, and rapid growth of research hotspots. ConclusionsInterest in VBHC research in China continues to grow, yet collaborative research and interdisciplinary integration remain limited. Future efforts should strengthen cross-institutional and cross-disciplinary collaboration, promote the development of shared data platforms, and build VBHC evaluation frameworks tailored to China’s institutional context.
