Visual analysis of global research hotspots in critical care nutrition based on VOSviewer and CiteSpace / 中华临床营养杂志

ABSTRACT

Objective:To analyze the worldwide development status and frontier hotspots in the field of critical care nutrition in recent 10 years, and to inform domestic future research direction.Methods:Publications on critical care nutrition researches between January 1, 2012 and December 31, 2021 were retrieved from Web of Science core database. CiteSpace and VOSviewer were used for visual analysis.Results:After screening, a total of 2,467 articles were included, with an overall increasing trend in the number of publications. A total of 11,301 authors devoted to critical care nutrition researches, among whom Daren K. Heyland (81) published the most globally and Academician Jieshou Li (9) published the most in China. The United States (812), China (221) and Canada (206) were the top 3 countries concerning numbers of publications in this field. The main research institutions were Harvard University, Queen's University and University of Leuven while Nanjing University ranked the highest domestically. Journal of Parenteral and Enteral Nutrition, Nutrition in Clinical Practice and Clinical Nutrition were the three most active journals in this field. Cluster analysis of keywords identified 11 representative cluster labels. Global focuses in critical care nutrition were influence of malnutrition, nutritional treatment pattern and energy and protein supplementation. Special interests were in the nutrition therapy in newborns, obese population and sepsis patients as well as intestinal microbial flora and coronavirus disease 2019.Conclusions:Critical care nutrition research is still under rapid development. Close collaboration between domestic core research circles and institutions should be emphasized while promoting international interactions. Researches on key issues such as energy and protein supplementation should be encouraged, so as to provide stronger evidence for better diagnosis and treatment standards in critical care nutrition.
