With the development of aging process, the frailty research has drawn an increasing amount of attention over the past decade. However, there is rare research on frailty from the perspectives of bibliometrics and visualization.
To analyze the knowledge structure and evolution of frailty research, and explore the hotspots and frontiers from the past decade.
Data of publications from 2010 to 2019 were retrieved from the Web of Science Core Collection database. We used CiteSpace V to analyze literature information, including countries/regions, institutions, authors, journals, knowledge base, research hotspots, and research frontiers.
A total of 12768 publications were identified. There was a steady growth trend for the quantity of publications over the past decade. The United States was the leading country for publications, and the leading institution was the Johns Hopkins University. Kenneth ranked first in the number of papers published. The Journal of the American Geriatrics Society was the most cited journal. Frailty, mortality, older adult, health, and risk were some of the high frequency keywords in co-occurrence analysis of keywords. Burst detection analysis of top keywords showed that frailty model, cohort study, meta-analysis, and cognitive impairment were the new research foci. Co-cited reference cluster analysis revealed the clustered network was divided into 13 clusters. The top three clusters were #0 Whitehall II, #1 aortic valve replacement , and #2 kegalle district.
The development prospects of frailty research could be expected. Researchers should pay more attention to the detection and interventions of frailty. Besides, the relationship between cognitive impairment and frailty as well as frailty problems of the elderly in low-income and lower middle-income countries were heating up.
