Abstract
Objective
To identify and examine definitions of frailty using qualitative thematic analysis.
Design
A qualitative meta-aggregative systematic review.
Data sources
The database search was performed using ASSIA, CINAHL, Cochrane Library, Embase, PsycINFO, PubMed and Google Scholar databases. Studies providing definitions of frailty, published in English from 1st January 2000 to 25th July 2018 were included.
Review methods
Data were extracted by independent reviewers for qualitative thematic analysis.
Results
In total, 86 studies met inclusion criteria. Five major themes with specific sub-themes were identified following thematic analysis including: (1) types of definitions (operational, conceptual, theoretical, older adults’ perspective); (2) characteristics of frailty (a multi-domain and dimensional state, deficits/decline, weakness, a continuum-dynamic concept, clinically identifiable); (3) associated factors (age, comorbidity, nutrition, sarcopenia, social networks and environment); (4) mechanism (reduced adaptability, hormonal dysregulation); and (5) changes in health status and adverse outcomes (disability, increased risk of mortality, other healthcare related outcomes such as increased dependency or risk of falls).
Conclusions
Several themes were found that defined frailty, focusing predominantly on operational definitions and frailty as a physical syndrome. A universally accepted standard definition, which includes all dimensions of frailty is currently warranted.
