This study adopted a bibliometric analysis to review the literature on Artificial Intelligence (AI) in nursing in the Web of Science (WOS) database from 1993 to 2020 by country/region, mainly journals, highly cited papers, authors, and keywords. The results show that the United States, the United Kingdom, and China are the top three countries/ regions. Computers Informatics Nursing and the Journal of the American Medical Informatics Association were the top two journals in terms of number of publications. The most cited journals are Journal of the American Medical Informatics Association, Nurse Education Today, and Journal of Biomedical Informatics. The top four most productive authors are all from nursing specialties. From the results of the keyword analysis, two research clusters were discovered, namely, the functionalities and roles of AI in nursing, and the technologies and research foci of AI in nursing. From 1993 to 2000, AI in nursing research focused on the development and application of expert systems; from 2001 to 2010, the research foci were the development of machine learning technologies, diagnostic systems and decision-making systems; and from 2011 to 2020, the main foci were the applications of machine learning, natural language and various artificial intelligence technologies, such as predicting the risk of infection and injury and monitoring health status. Accordingly, this study provides researchers and policy makers with information on the role of AI in nursing and research trends, as well as several recommendations for future research.
