Frailty Index. The frailty index (FI), developed by our group, is one of the leading paradigms for understanding frailty at population, personal, organ, and tissue levels (with cellular deficit evaluation in development).
25 de jun. de 2024 · The frailty index (abbreviated FI) is a simple yet effective tool to assess frailty — a state of increased vulnerability to external stressors. The frailty index consists of 30-40 variables that measure the patient's health deficits.
The frailty index was calculated using 28 baseline variables, all of which were health status deficits measured by use of questionnaires and physical examination. We defined three categories of frailty status: robust (frailty index ≤0·10), prefrail (frailty index >0·10 to <0·25), and frail (frailty index ≥0·25).
The frailty index ( FI) can be used to measure the health status of older individuals; it serves as a proxy measure of aging and vulnerability to poor outcomes. FI was developed by Dr. Kenneth Rockwood and Dr. Arnold Mitnitski at Dalhousie University in Canada.
2 de sept. de 2022 · The objective of this systematic review of population studies was to compare the ability of the frailty index (FI) and frailty phenotype (FP) instruments to predict all-cause mortality in older people.
18 de dic. de 2021 · The frailty index (FI) represents the accumulated deficit model of frailty [ 1] and is a continuous variable (ranging from zero to a theoretical maximum of one) derived from a list of potential health deficits [ 2 ]. Increasingly, FI scores are being used to assign individuals to frailty categories.
12 de ago. de 2021 · Frailty is a multiply determined, age-related state of increased risk for adverse health outcomes. We review how the degree of frailty conditions the development of late-life diseases and...
Frailty, which is a geriatric syndrome that affects 5% to 17% of older adults, is a state of increased vulnerability across multiple health domains that leads to adverse health outcomes. Frail...
25 de ago. de 2021 · Frailty is commonly measured using the frailty index (FI), based on the accumulation of a number of health deficits during the life course. The mechanisms underlying FI are multifactorial and not well understood, but a genetic basis has been suggested with heritability estimates between 30 and 45%.
27 de nov. de 2018 · The frailty index is a ratio of the number of deficits that an individual has accumulated divided by all deficits measured, whereas the phenotype specifies frailty as represented by poor performance in three of five criteria (i.e., weight loss, exhaustion, weakness, slowness, lack of activity).
