A

- Falls history

- Assessment of cognition (check with collaterals if change)

- Continence assessment

- Social and functional history (where do they live, do they have carers, do they have adaptations in home)

Who is in involved in a Comprehensive Geriatric Assessment (CGA) and what is the aim of this assessment?

A

Team: Geriatrician, Nurse Specialist, OT, Physio, Pharmacist, S+L, Dietician

Q

What is a section 2 and section 5 when organising discharge from hospital for an older patient?

A

Section 2: Referral to social services if patient is likely to need comunity care once discharge. to assess for funding e.g care home, carers. Patient is then allocated a social worker who is responsible for their package of care

Section 5: Nursing staff alert social services when patient is medically fit for discharge so social services need to start decisive action towards discharge

Q

How is delirium managed?

A

Supportive care: treat underlying cause, orientate patient to time and place

Pharmacological treatment (Lorazepam and Haloperidol): only if patient is a harm to themselves or others.

Haloperidol is contraindicated in Parkinson’s.

  • Decaff drinks
  • Good bowel habit
  • Regular toileting
  • Bladder retraining
  • Pelvic floor exercises

2nd Line - Pharmacology

  • Do not give oxybutynin (anticholinergic) to elderly due to risk of postural hypotension and falls

3rd Line - Surgery

39
Q

What are some of the causes of faecal incontinence in the elderly?

A

- Faecal impaction with overflow diarrhoea

- Neurogenic dysfunction

- Gaping anal sphincter due to haemorrhoids or chronic constipation

40
Q

How can you tell if faecal incontinence is due to spinal cord pathology?

A

Reduced anal sphincter tone and sensation

41
Q

How do you examine someone with faecal incontinence?

A

PR looking at:

  • Anal tone
  • Sensation
  • Prostate
  • Visual inspection of anus
  • Stool type if any in rectum
42
Q

What should raise your suspicion of faecal impaction? (rectum full of soft or hard stool)

A
  • Smearing
  • Small amount of type 1 stool
  • Lots of type 6/7 stool
  • Mass palpated on abdominal exam
  • Urinary retention (must always due PR with this to check for impacted rectum and large prostate)
43
Q

Why is chronic constipation and faecal impaction so dangerous?

A

Stercoral perforation and ischaemic bowel which can lead to shock and death

44
Q

How is faecal impaction managed?

A

Hard stool: Give stool softener like macrogol then a few days later give stimulant like glycerol or use enema docusate sodium.

Can also give Ispaghula Husk if cannot increase fibre in diet

Soft Stool: Give stimulant or enema

Difficult cases: manual evacuation (risk of perforation outweighed by benefits of improving patient’s symptoms and wellbeing)

Give laxatives prophylactically if elderly and taking another drug that has constipation as a side effect. Always encourage fluids, fibre and exercise!

45
Q

How is chronic diarrhoea treated?

A
  • Bowel imaging and stool culture to rule out underlying causes
  • Stop any causative medications
  • Rule out faecal impaction

Treatment:

  • Regular toileting
  • Dietary review
  • Low dose loperamide with enema regimes
46
Q

A
  • Not allowed to drive for one month after a stroke or TIA. After this you can drive if no permanent neurological deficit
  • If recurrent TIAs cannot drive for 3 months
57
Q

If a patient has a TIA or stroke, when should they be referred for a carotid endarterectomy?

A

If carotid stenosis 50-99% should be assessed and referred within a week of TIA/stroke

Should then have surgery within 2 weeks of onset of stroke/TIA

58
Q

  • Short duration
  • Chronic
  • Opioid induced
A

Short (not responded to increased fibre): Bulk forming laxative with adeqaute fluid intake. If still hard give osmotic laxative. If soft just give stimulant

Chronic: Same as above then slowly withdraw when regular bowel habits. If using 2 then withdraw stimulant first. If 2 laxatives still not working at highest dose for 6 months, give prucalopride, reassess if not working after 4 weeks

Opioid induced: Osmotic and Stimulant. AVOID bulk forming

Q

Why may someone with dementia in a nursing home have poor oral intake?

A
  • Difficulty chewing and swallowing
  • Constipated
  • Drug side effects
  • Anorexia from dementia
  • Not physically active
80
Q

What types of fluid and food consistencies can the SALT team recommend for patients with swallowing difficulties e.g dementia?

A

Fluids: thickened fluids to either syrup, custard or pudding consistency

Foods:

- Blended diet: B is thin blended like soup, C is thick blended and can be moulded/holds own shape

- Mashed diet: D still has some lumps in as not pureed/sieved

- Soft diet: just avoiding high risk foods for aspiration

- Normal diet

81
Q

Should dementia patients be fed with enteral feeding e.g NG/PEG?

A

No

  • Higher risk of aspiration with NG than swallow in dementia
  • Does not improve nutrition and survival
  • Unpleasant procedure and patient may try to pull it out
82
Q

What does feeding at risk mean and what do you have to tell the patient’s family with this?

A

Patient continues to eat and drink despite a significant risk of aspiration/choking

Tell family it helps them to maintain quality of life, that other options (e.g NG) may also not reduce risk of aspiration, ask them how they want to treat further aspiration pneumonias e.g ?no hospitalisation

83
Q

What is a best interest decision and when is it made?

A

A decision made for a person who lacks capacity to make their own decision

84
Q

What is an advanced care plan?

A

A conversation between a patient and their family/carers/GP outlining their future wishes and priorities for care/treatment

This is made whilst the patient still has capacity

85
Q

What is a ReSPECT form?

A

Personalised recommendations for a person’s clinical care and treatment in a future emergency in which they are unable to make or express choices

Can be reviewed and is not legally binding

Only legally binding if ADRT is signed

  • Serum B12 and folate
  • ABG
  • Specific cultures (MSU, sputum)
  • Lumbar Puncture (if meningism or headache and fever)
89
Q

How should you manage a patient with acute confusion?

A
  • Withdraw or reduce any drugs causing confusion
  • Correct biochemical derangements
  • If high likelihood of infection treat promptly with antibiotics
  • Relieve exacerbating symptoms (pain, urinary retention, constipation, thirst)
  • Avoid major tranquillisers where possible
  • Monitor AMTS
  • Communicate with the relatives
