Objective To analyze the current research status, hotspots, and trends related to the implementation of advance care planning (ACP) both domestically and internationally.Methods Relevant literature records were retrieved from the China National Knowledge Infrastructure (CNKI) and the Web of Science Core Collection.The CiteSpace 6.3.R1 software was used to conduct a visual analysis of the authors, institutions, keywords, and other elements included in the literature.Results A total of 194 Chinese articles and 2,437 English articles were included.The volume of research on the implementation of advance care planning has shown a gradual increase.Internationally, collaborative networks among authors and institutions are more tightly knit, while domestic collaborations are relatively dispersed, with fewer inter-regional partnerships and a need for enhancement of academic inf-luence.The top five keywords related to implementation research in China included advance directives, reviews, palliative care, qualitative research, and pre-authorization, while internationally, they were advance care planning, palliative care, end-of-life, outcome, and intervention.Conclusion Research on the implementation of advance care planning, both domestically and internationally, primarily focuses on intervention populations, implementation methods, and research contents.Future research could develop ACP practice models that align with China′s traditional cultural values and strengthen community and family involvement.There is a need to encourage collaboration between academic institutions and clinical practices to promote and refine research on ACP implementation.
