Bibliometric analysis of frailty in dialysis patients: knowledge mapping and trends

Frailty is a critical concern in the growing dialysis population. This study employs bibliometric analysis to map the knowledge landscape and identify research hotspots regarding frailty in dialysis patients.

We retrieved publications from the Web of Science Core Collection (January 1, 2007-February 8, 2025). After screening titles and abstracts, relevant articles were included for analysis. Using CiteSpace software, we visually analyzed authorship, institutions, countries, keywords, and burst keywords.

A total of 243 articles were included. Annual publications showed a marked upward trend. The United States was the leading country, with Johansen K.L. and the University of California System as the most influential author and institution, respectively. Keyword analysis revealed four central research hotspots: (1) frailty assessment, (2) interventions, (3) adverse outcomes, and (4) frailty in elderly dialysis patients. The analysis of burst keywords indicates that frailty assessment and its link to all-cause mortality are the current research frontiers.

This study conducted a comprehensive bibliometric analysis on research related to frailty in dialysis patients, revealing the research hotspots and trends in this field. It fills the gap in the panoramic view of frailty research in this high-risk subgroup and provides valuable references for future research in this area.
