Geriatrics PTS Flashcards
Define Frailty
- State of increased vulnerability resulting from ageing associated decline in functional reserve
- Across multiple Physiological systems
- Resulting in compromised ability to cope with everyday or acute stressors
What are the 4 components of the comprehensive geriatric assessment?
- Medical assessment
- Functional assessment
- Psychological assessment
- Social and environmental assessment
What is the medical assessment made up of?
- Doctor, nurse, pharmacist, dietician, SALT
- Problem list, comorbidities, medication review, nutritional statues
What mades up the functional assessment?
- OT, PT, SALT
- Assesses ADLs, activity, exercise status, gait, balance
What is the psycological assessment comprised of?
- Doctor, nurse, OT, psychologist
- Cognitive status testing, mood/depression testing (PHQ-9 questionnaire)
What is the social and environmental assessment comprised of?
- OT and social worker if needed
- Informal support needs and assets, care resource eligibility, home safety
What are the features of delirium?
- Acute onset
- Fluctuating course
- Inattention
- Altered level of consciousness
- Usually reversible
- Associated with underlying medical cause
What are the features of dementia?
- Chronic illness
- Progressive course
- No clouding of consciousness
- No underlying/reversible cause
What assessment tool is used for delirium?
4-AT
What causes delirium?
- Infection
- Drug use - withdrawal or new medications interaction
- Reduced sensory input - blind, deaf, changing environment
- Intracranial problems - stroke, seizures, haemorrhage
- Electrolyte imbalances
- Constipation
- Urinary retention
- Heart problems - MI, arrhythmia
How is delirium managed?
- Treat underlying cause
- Manage the environment
6 ways to alter environment to help delirium
- Clocks and calendars to maximise orientation
- Ensure hearing aids/glasses are worn
- Photos of family members
- Consistency of staff members
- Quiet bay/side room if possible
- Sleep hygiene
What are the complications of a long lie following a fall?
- Pressure ulcers
- Dehydration
- Rhabdomyolysis
- Hypothermia
How do you investigate pressure ulcers?
- CRP, ESR
- WCC
- Swabs
- Blood cultures
- X-ray for bone involvement
How are pressure ulcers managed?
- Antibiotics
- Wound dressing
- Pain relief
- Debridement if grade 3/4
What is osteoporosis?
- Decreased bone mineral density due to imbalance between remodelling and resorption
- Increases risk for fractures - particularly spine, hip and neck of femur
7 risk factors for osteoporosis
- Smoking
- Early menopause
- Steroid use
- Underweight
- Inactivity
- Alcohol
- Elderly
How is osteoporosis managed?
- Bisphosphonates - Zoledronate, Alendronate
- IV once a year or oral once a week (on an empty stomach sit upright for half an hour after)
What is the tool used to assess multi-nutritional status?
MUST screening tool (malnutrition universal screening tool)
What is refeeding syndrome?
- Metabolic disturbances as a result of reintroduction of nutrition to patients who are starved/severely malnourished
What are the biochemical features of refeeding syndrome?
- Hypophosphataemia
- Hypokalaemia
- Thiamine deficiency
- Abnormal glucose metabolism
What are some complications of re-feeding syndrome?
- Cardiac arrhythmias
- Coma
- Convulsions
- Cardiac failure
How is re-feeding syndrome treated?
- Monitor blood biochemistry (phosphate, glucose, sodium, potassium)
- Commence re-feeding with guidelines
Risk factors for pressure ulcers
- Peripheral vascular disease
- Immobility/long lie
- Dehydration
- Obesity
- Malnourishment
- Old age
Environmental causes of falls in elderly people
- Loose rugs
- Pets
- Furniture
- Unstable footwear
Power/balance causes of falls in elderly people
- Inactivity leading to muscle weakness
- Dizziness/loss of balance/ loss of proprioception (vertigo)
- Pain, MS, osteoarthritis
- Previous fall leading to decreased confidence
Cardiovascular causes of falls in elderly people
- Vasovagal syncope
- Situational syncope (micturition)
- Postural hypotension
- Myocardial infarction
- Arrhythmia
- Dehydration/shock
Neurological causes of falls in elderly people
- Stroke
- PD
- Gait disturbance
- Visual impairment
- Peripheral neuropathy
- Myopathy
What are some medications that increase risk of falls in elderly people?
- Benzodiazepines (sedative)
- Diuretics
- Anti-hypertensives
- Antidepressants
- Antipsychotics
- Polypharmacy
Miscellaneous causes of falls in elderly people
- Infection/sepsis
- Delirium
- Hypoglycaemia
- Incontinence
- Alcohol (intoxication, neuropathy, Korsakoff’s/Wernicke’s)
5 features of a Parkinsonian tremor
- Pill rolling
- Worse at rest
- Reduced on distraction
- Reduced on movement
- Asymmetrical
What is the underlying pathophysiology of Parkinson’s?
Loss of dopaminergic neurones in the substantia nigra
