Geriatrics - frailty and comprehensive assessment Flashcards
define frailty
A susceptibility state that leads to a person being more likely to lose function in the face of a given environmental challenge.
name the theories of aging
Stochastic, programmed, homeostatic failure
what happens to inter-induvidual variability with age?
Increases
what is dyshomeostasis
frailty, impaired function of any organ system, inability to maintain a steady state.
name the 4 decompensated frailty syndromes
falls, delerium, immobility and incontinence, functional loss
what are the effects of aging on heat stress?
reduced sweat gland oiutput, skin blood flow, smaller increase in cardiac output, less redistribution of blood flow from renal and splanchnic circulation.
”” cold stress
reduced peripheral vasoconstriction and metabolic heat production
what is social dyshomeostasis and give and eg
difficulty caused by environmental insults not just bio-medical (e.g. death of a spouse)
how does hyperthyroidism preset I people with frailty?
depression, cognitive impairment, ,nuscle weakness, atrial fibrillation, heart failures, angina.
withh age what happens to - body composition (ALSO thinnk about what happens to other systems
more fat, cenntral fat, reduced total body water, reduced bone mass, reduced energy requirement, reduced muscle mass
what is susceptibility state composed of?
multimorbidity, frailty, disability
frailty phenotype as defined by Fried…
unintentional wieght loss, exaustion, weak grip strength, slow walking speed, low phhysicl activity. (need 3/5 of the criteria)
what are the failty syndromes?
falls, immobility, delerium, fucntional loss ALSO care home, list of 6 or more medicines (composes the HIS frailty - if this person would benefit from a comprehensive geriatric assessment)
define a person centred/ goal-centred approach
Means we do what the patient wants (not what the doctor wants)Preserves autonomy. Is an effective way of dealing with multimorbidity and competing clinical priorities.
iatrogenic harm…
harm done by doctors/ healthcare professionals through admisteration of drugs.
