OLDER PERSONS MEDICINE Flashcards
What is CGA?
Comprehensive geriatric assessment
What is CGA used for?
multidimensional, interdisciplinary diagnostic process to determine the medical, psychological, and functional capabilities of a frail older person in order to develop a coordinated and integrated plan for treatment and long-term follow-up
What is the emphasis of CGA?
quality of life
functional status
prognosis
outcomes
Why is CGA important?
better outcomes, including reduced readmissions reduced long-term care
greater patient satisfaction
lower costs
Who is in a CGA team?
geriatrician
nurse specialist
occupational therapist
physiotherapist
pharmacist
others as needed (speech and language therapist, dietician)
What are the domains of CGA?
Problem list – current and past
Medication review
Nutritional status
Mental health – cognition, mood and anxiety, fears
Functional capacity
Social circumstances
Environment
What is considered when assessing functional capacity in CGA?
basic activities of daily living
gait and balance,
activity/exercise status
instrumental activities of daily living
What is considered when assessing social circumstances in CGA?
informal support available from family or friends,
social network such a visitors or daytime activities, eligibility for being
offered care resources
What is considered when assessing environment in CGA?
home environment, facilities and safety within the home environment, transport facilities ,accessibility to local resources
Is faecal incontinence ever normal?
No, always abnormal
How does a patients rectum change as they age?
the rectum can become more vacuous and the anal
sphincter can gape due to a number of factors including haemorrhoids and chronic constipation.
Older people cannot exert the same amount of intra-abdominal pressure and muscle tension to force out constipated stool.
Why is diminished anal tone sensation important not to miss?
Could indicated spinal cord pathology-needs urgent management
What is the most common cause of faecal incontinence in OP?
1)Faecal impaction with overflow diarrhoea
2nd- neurogenic
What type of stool you be suspicious of overflow with impaction?
smearing, small amount of type 1 stool or copious type 6/7 stool with no sensation of defaecation
What are the risks of chronic constipation?
stercoral perforation and ischaemic bowel
What is the management of chronic constipation?
utilising enemas for rectal loading and stool softeners and stimulants.
Stimulants don’t work on hard stool.
Some enemas will not work if the rectum is loaded with hard stool and will merely fall out.
Management of diarrhoea in OP?
underlying causes must be excluded by bowel imaging and stool culture
potentially causative medications removed then care
can focus on firming the stool.
Faecal impaction must be excluded
Pharmacological management of diarrhoea in OP?
Low dose loperamide
What is delirium?
Acute, transient and reversible state of confusion ( global disorder of cognition and consciousness). often due to other cause (infection, drugs, dehydration).
Onset is acute and the cognition of the patient can be highly fluctuant over a short period of time.
What 2 states of delirium can you get?
HYPOactive
HYPERactive
what are clinical features of hypoactive delirium?
(often confused with depression)
Lethargy
withdrawn
Inattention
Slowness with everyday tasks
Excessive sleeping
what are clinical features of hyperactive delirium?
Agitation
Delusions
Hallucinations
Wandering
Aggression
Patients CAN fluctuate between hypoactive and hyperactive delirium - TRUE OR FALSE?
TRUE
Causes of delirium? CHIMPS PHONED
Constipation
Hypoxia
Infection
Metabolic disturbance
Pain
Sleeplessness
Prescriptions
Hypothermia/pyrexia
Organ dysfunction (hepatic / renal impairment)
Nutrition
Environmental changes
Drugs (over the counter, illicit, alcohol and smoking)
Assessing the confused patient:
in medical notes look for relevant past medical history such as…
Previous episodes of confusion
head injury
recent admission
stroke
atherosclerosis
Assessing the confused patient:
in medical notes look for current medications….
review drugs that may cause / contribute to confusion
e.g. opiates
anticholinergics
benzodiazepams
steroids
Antihistamines
antipsychotics
antidepressants
parkinson drugs
Assessing the confused patient:
in medical notes look for social Hx….
Home situation - carers / live alone
evidence of how coping
excess alcohol
excessive drug use
Patient’s PC: a fall.
What would you ask in Hx?
WHO saw you fall?
WHEN did you fall?
WHERE did you fall?
WHAT happened before/during/after?
WHY do you think you fell?
HOW many times have you fallen?
Meds taken? How do they mobilise usually?
What PMH may be relevant in fall Hx?
CVS - arrhythmia, CVD
Resp - COPD
Neuro - Parkinson’s, peripheral neuropathy, stroke, dementia
GU - UTIs, incontinence
GI - Diverticulitis, chronic D-, ALD
MSK - Arthritis, chronic pain, fractures
Why review meds in OP who has had a fall?
Polypharmacy is RF for falls. Meds have SE for increasing risk of falls.
Name meds that increase risk of falls in OP
BBlockers
DM meds
HTN meds
Benzodiazepines
Abx
What bloods do you need to request for a confusion screen for your patient? And what looking for?
FBC (e.g. infection, anaemia, malignancy)
U&Es (e.g. hyponatraemia, hypernatraemia)
LFTs (e.g. liver failure with secondary encephalopathy)
Coagulation/INR (e.g. intracranial bleeding)
TFTs (e.g. hypothyroidism)
Calcium (e.g. hypercalcaemia)
B12 + folate/haematinics (e.g. B12/folate deficiency)
Glucose (e.g.
hypoglycaemia/hyperglycaemia)
Blood cultures (e.g. sepsis)
What urinalysis do you need to do for a confusion screen for your patient? Why is this complicated for older patient?
most elderly patients will have a positive urine dip- not enough to diagnose UTI in elderly as cause of delirium.
Need other evidence:
WCC ++
suprapubic tenderness
dysuria
Offensive urine
+ve urine culture
What questions does the Abbreviated Mental Test Score (AMTS) ask?
Ask the patient:
- “What is your age?”
- “What is the time to the nearest hour?”
- Give the patient an address, and ask them to repeat it at the end of the test (e.g. “42 West Street”)
- “What is the year?”
- “What is the name of this place?” or “What is your house number?”
- Can the patient recognise two persons (e.g. doctor, nurse)?
- “What is your date of birth?” (day and month sufficient)
- “In what year did World War 1 begin?”
- “Name the present monarch/prime minister/president”
- “Count backwards from 20 down to 1”
Each questions answered CORRECTLY. gets 1 point.
SCORE OF 6 or less suggests DEMENTIA ? DELIRIUM - further tests to confirm which
What would you look for in clinical examination of someone you are assessing for delirium?
Vital signs (e.g. fever in infection, low SpO2 in pneumonia)
Level of consciousness (e.g. GCS/AVPU)
Evidence of head trauma
Sources of infection (e.g. suprapubic tenderness in urinary tract infection)
Asterixis (e.g. uraemia/encephalopathy)
There is a patient with suspected delirium- you are asked to do a confusion screen.
What 3 categories of investigation does this involve?
Bloods
Urinanalysis
Imaging
What bloods do you need to request for a confusion screen for your patient? And what looking for?
FBC (e.g. infection, anaemia, malignancy)
U&Es (e.g. hyponatraemia, hypernatraemia)
LFTs (e.g. liver failure with secondary encephalopathy)
Coagulation/INR (e.g. intracranial bleeding)

hypoglycaemia/hyperglycaemia)
Blood cultures (e.g. sepsis)
What urinalysis do you need to do for a confusion screen for your patient? Why is this complicated for older patient?
most elderly patients will have a positive urine dip- not enough to diagnose UTI in elderly as cause of delirium.
Need other evidence:
WCC ++
suprapubic tenderness
dysuria
Offensive urine
+ve urine culture
What imaging do you need to do for a confusion screen for your patient? What looking for?
CT head- intracranial pathology (bleeding, ischaemic stroke, abscess)
Chest X-ray - pneumonia, pulmonary oedema
What is definitive management of delirium?
treat underlying cause
Supportive management of delirium?
- Pt has access to aids e.g. hearing aids/ glasses/ walking stick
- encourage independent activities e.g. washing / eating/ toileting
Environmental management of delirium?
- Access to clock and other orientation reminders
-familiar obects - photos/ wear own clothes
- involve family / regular carers
- ensure lighting and temperature optimal
Why must be very careful in treating an elderly patient for delirium when they have a background of Parkinsons / Lewy Body dementia?
Haloperidol 0.5 mg is the 1st-line sedative (oral preferred or IM if refused to take + immediate threat to others)
Parkinson’s disease- antipsychotics can worsen symptoms
1. Reduce Parkinson meds
2. if urgent treatment - use atypical antipsychotics e..g clozapine
What score can we use in a clinical setting to evaluate for frailty?
Rockwood clinical frailty score >65yrs
Some steps to prevent delirium?
avoid drugs that cause: opiates / benzodiazepines
asses factors that cause: pain control / drugs
Identify those at risk and monitor
use supportive and environmental management approaches for all patients
Bedside investigations for OP that has Hx of fall?
Vital signs - BP, HR, RR, O2 sats, temp
Lying and standing BP (orthostatic hypotension)
Urine dip (blood ++ in rhabdo)
ECG - bradycardia, arrythmia
Cognitive screen
Blood glucose (Hypoglycaemia)
Blood investigations to do for OP w/ Hx of fall?
FBC
U+Es - dehydrated, electrolyte abnorm, rhabdo
LFTs - chronic alcohol use
Bone profile - Ca levels in malignancy, over supplementation of Ca
Imaging investigations for Op w/ Hx of fall?

How are OP who have fallen assessed?
Falls risk assessment
- ID people over 65 who have had 1+ falls in last 12/12.
- Take full Hx
- note RF
- assess gait and balance - use Timed Up and Go test +/- Turn 180deg test.
