Frailty Index (FI) = (number of health deficits present) ÷ (number of health deficits measured) For example, a person with 20 of 40 deficits collected has an FI score of 20/40 = 0.5; whilst for someone with 10 deficits, the FI score is 10/40 = 0.25. The FI takes advantage of the high redundancy in the human organism.
Frailty is a clinical state of increased vulnerability and the decline of organ systems due to the aging processes [2] and external factors. It is related to morbidity and mortality. [3] There are many criteria using to detect frailty, such as the frailty phenotype, [4] frailty index, [5] or clinical frailty scale. [6]
The Clinical Frailty Scale (CFS) is a scale used to assess frailty which was evolved from the Canadian Study of Health and Aging. It is a 9-point scale used to assess a persons frailty level, where a score of 1 point would mean a person is very fit and robust, to a score of 9 points meaning the person is severely frail and terminally ill. [14]
In full generality, the accelerated failure time model can be specified as [2] (|) = ()where denotes the joint effect of covariates, typically = ([+ +]). (Specifying the regression coefficients with a negative sign implies that high values of the covariates increase the survival time, but this is merely a sign convention; without a negative sign, they increase the hazard.)
Using a structured-interview protocol developed by Charles Hughes, [1] Leonard Berg, John C. Morris and other colleagues at Washington University School of Medicine, a qualified health professional assesses a patient's cognitive and functional performance in six areas: memory, orientation, judgment & problem solving, community affairs, home & hobbies, and personal care.
The scale was originally introduced in 1957 by Dr. John Rankin of Stobhill Hospital, Glasgow, Scotland as a 5-level scale ranging from 1 to 5. [ 3 ] [ 4 ] It was then modified by either van Swieten et al. [ 5 ] or perhaps Prof. C. Warlow's group at Western General Hospital in Edinburgh for use in the UK-TIA study in the late 1980s to include ...
The ISS is based (see below) upon the Abbreviated Injury Scale (AIS). To calculate an ISS for an injured person, the body is divided into six ISS body regions. These body regions are: Head or neck – including cervical spine; Face – including the facial skeleton, nose, mouth, eyes and ears; Chest – thoracic spine and diaphragm
The Berg Balance Scale is used by clinical exercise physiologists, physiotherapists and occupational therapists to determine the functional mobility of an individual. This test can be administered prior to treatment for elderly individuals and patients with a history of but not limited to stroke, [1] Multiple sclerosis, Parkinson's disease, Ataxia, vertigo, cardiovascular disease and ...
