Frailty Flashcards
What is frailty
Condition characterised by loss of biological reserves and vulnerability to adverse outcomes
How do simpl conditions affect frail people differently
For a given insult - more prfound deterioration and longer recovery than for a non frail person.eg falls, delirium, confusion - disproportional to insult. Accumulation of physiological systems not working.polypharmacy adds to it.
What is the fragility index
Frailty Index score = Number of deficits in an individual/Total number of deficits measured
e.g. in a dataset with 50 health deficits, a person with 10 things wrong (10 deficits) has a frailty index score of 10/50 = 0.20.
Why does frailty cccure
- Frailty is a multiply determined risk state manifest as not everyone of the same age having the same risk of death (or other adverse outcomes)
- It arises due to the stochasticity of age-related deficit accumulation across the life course
- People are frail when they have lots of things wrong with them
- What does this mean for treatment and care?
What are non-specific presentations of frailty
- Falls, immobility, off legs, collapse ? cause
- Confusion (delirium and/or dementia)
- “Acopia” or “social admission” (phrases never to use!)
- Other diffuse or multiple statements related to disability
What are the reasons behind non specific presentations
- Homeostatic failure
- Multiple pathology & polypharmacy
- Differential challenge
Describe issues with homeostasis that can occur
- Balance, temperature, blood pressure, sodium, etc
- Biological systems usually robust: multiple feedback loops
- Failure either due to overwhelming single disease, or lesser disease with multiple co- morbidity
What external factors can exacerbate Riley
Vulnerable homeostatic systems need protection from challenge…..but…
• Living alone • Poverty
• Poor housing • Ageism
What should be done when a non specific presentation is found
• When found:
expect multiple pathology
look beyond the acute precipitant or consequence
• Medical intervention could be at the acute precipitant
at co-pathology • Rehabilitation
What are implications orpractise in terms of frailty
- Use frailty to differentiate and prognosticate
- Tailor management accordingly
- Frailty complex, solutions will need to be complex… Comprehensive Geriatric Assessment
