Co-word clustering analysis for hot research topics in enteral nutrition in critically ill patients based on PubMed / 中华临床营养杂志

ABSTRACT

Objective:To identify hot research topics about enteral nutrition in critically ill patients in PubMed from 2011 to 2020, and to explore the current research landscape and development directions.Methods:Literature about enteral nutrition published from 2011 to 2020 were retrived in the PubMed database. Subject headings in publications were extracted using BICOMB and then two-way cluster analysis was performed using gCLUTO to cluster the subjects and generate cluster curve, matrix and tree diagram.Results:A total of 5,686 publications were included, mostly published in Unites States and United Kingdom and with an increasing trend. The researches focused on five aspects including feeding practice in very low birth weight infants, prevention and control of aspiration pneumonia in critically ill patients, catheterization methods in enteral nutrition, protein intake in critically ill patients, and clinical implementation of enteral nutrition guidelines in critically ill patients.Conclusions:Much importance has been attached to enteral nutrition researches over the recent decade. Analysis of hot research topics in enteral nutrition is beneficial to understanding the current research landscape and development directions and providing references for practice, research and education of enteral nutrition.
