Visualized analysis of trends and hotspots in global refeeding syndrome: A bibliometric analysis study (2000-2024).

Refeeding syndrome (RFS) is a serious metabolic condition that arises when nutritional support is reintroduced to malnourished patients, particularly after prolonged starvation. This study conducts a bibliometric analysis of RFS research, mapping global trends, key contributors, and collaborative networks. A comprehensive literature search was performed using the Web of Science Core Collection database, with publications spanning from 2000 to 2024. We analyzed data using VOSviewer, CiteSpace, and the R package "bibliometrix," focusing on publication volume, citations, collaborations, and keyword trends. The analysis included 530 publications, with the USA leading in research output, followed by the UK and Australia. Top institutions included the University of London, University of California System, and University of Bern. Key journals contributing to the field were Nutrition in Clinical Practice, Clinical Nutrition, and Nutrients. Notable authors were Zeno Stanga, Philipp Schuetz, and Arthur R.H. van Zanten. Core keywords included "multicenter," "critically ill patients," and "prevention" with recent bursts in keywords such as "prevention," "outcome," and "medical inpatients." This bibliometric study provided a comprehensive overview of the evolving research landscape concerning RFS. Key priorities included identifying at-risk populations, optimizing nutritional interventions, and standardizing management to address metabolic challenges.
