Professional nursing staff should use frailty indicators in a timely fashion to assess the status of frailty in older people and should effectively develop frailty prevention strategies to decrease the risk for hospitalization and to enhance quality of life for older adults.
Background:
The World Health Organization has identified frailty as a crucial factor affecting successful aging. Systematic literature reviews have yet to focus on the relationship between stages of frailty and disability in community-dwelling older adults.
Purpose:
The purpose of this study was to investigate the relationships between various frailty types and disability in community-dwelling older adults and to explore how various frailty criteria have been used to assess disability in this population.
Methods:
A systematic literature review and meta-analysis were conducted on articles from the following databases: Cochrane Library, CINAHL, PubMed, and Ovid. Database search criteria included articles that were published between January 2001 and July 2017 and study samples that included community-dwelling adults aged 60 years and older. We excluded studies that were conducted in institutions or hospitals and experimental studies on frailty. Two reviewers independently assessed eligibility and extracted data. A random-effects model was used to analyze the literature and to calculate the pooled disability of frailty.
Results:
In total, nine studies with a total sample of 32,998 participants that recorded 8,666 disabilities and a mean follow-up time of 30.4 months (
SD
= 29.26) were pooled for the meta-analysis. Using various indicators to predict the risk of disability compared with robust older adults, those with frailty faced a higher risk of disability, followed by older adults at risk of frailty.
Conclusions/Implications for Practice:
Frailty is a crucial health consideration among older adults. Those who are frail have the highest relative risk of disability, followed by those at risk of frailty. Early assessment of frailty may effectively prevent the occurrence of frailty-induced disability in older adults.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
