Define stress incontinence?

A
  • This is the involuntary leakage of urine on effort, exertion, sneezing or coughing causing increased intra-abdominal pressure without a detrusor contraction

Q

Explain what is meant by overflow incontinence?

A
  • Occurs due to the bladder not emptying properly when urinating causing urine to leak out later
  • This is more common in men due to prostatic obstruction but in women can occur due to obstruction of the urethra (caused by prolapse) or a poor contractile bladder muscle

Q

Symptoms of overflow incontinence?

A
  • Ask about symptoms of prostatic enlargement – dribbling, incomplete emptying, poor stream, difficulties initiating stream
  • Acutely the person may complain of painful urinary retention, in later presentation they may have a palpable bladder, chronic retention, wet at nights and renal impairment, mass is dull to percussion

Q

Management of overflow incontinence?

A

Treat prostatic enlargement - alpha blockers to relax bladder neck muscles e.g. alfuzosin, tamzulosin. 5 alpha reductase inhibitors to shrink the prostate e.g. finasteride

If someone has had chronic/ bad acute retention they may need taught self catherisation and may never be able to pass urine spontaneously again

Q

Explain what carotid sinus syndrome is and how you test for it?

A
  • More common as age increases, there is abnormal activation of carotid sinus (where baroreceptors located) which leads to symptoms secondary to cerebral hypoperfusion
  • If suspect can do CS massage test looking for pause in HR > 3 seconds, drop in systolic BP > 50 or both
  • Some centres you can do a tilt test
  • These need referred to cardio – may need a pacemaker
20
Q

What extra thing do you need to ask about in a falls history?

A

bone protection

21
Q

List Fried Frailty characteristics?

A

  3. Weakness measured by grip strength
  4. Slow walking speed (1m per second, if slower then that’s a slow walking speed)
  5. Low physical activity
22
Q

What is the clinical frailty scale/ rockwood frailty scale?

A
  • Deficit accumulation – another way to define frailty
  • Common and used on wards
  • Frailty
23
Q

What is electronic frailty index?

A
  • Useful in general practice when have more information

* Uses routine data to identify older people with mild moderate and severe frailty

24
Q

Explain what is meant by the comprehensive geriatric assessment and the components?

A

MDT approach to care essentially composed of medical, functioning, psychological and social/ environment

Medical
–	Problem list
–	Co-morbid conditions and disease severity
–	Medication review
–	Nutritional status
Functioning 
–	Basic ADLs
–	Extended ADLs
–	Activity/exercise status
–	Gait and balance

Psychological
– Mental status/cognitive function
– Mood/depression testing

Social/ Environment 
–	Informal needs and assets
–	Social circle
–	Care resource eligibility & resources
–	Safety
25
Q

What is delirium?

A
  • An acute deterioration in mental functioning arising over hours or days that is triggered mainly by acute medical illness, surgery, trauma or drugs
  • Pathophysiology is not well understood
26
Q

Risk factors for delirium?

A
  • Increased age (as someone gets older there is less needed to cause it- a young person could go into delirium but the trigger would have to be larger)
  • Pre-existing cognitive impairment
  • Post-operative
  • Sensory impairment (makes orientation worse)
  • Previous episode of delirium
  • Drug/ alcohol dependence
  • Depression
  • Polypharmacy
  • Multiple co-morbidities
  • ICU Admission
27
Q

Causes of delirium?

A

almost anything but some common causes below:

  • D- Drugs (most common= benzodiazepines, narcotics, anticholinergics (e.g. oxybutynin))
  • E- electrolyte disturbance (e.g. hyponatraemia)
  • L- lack of drugs (withdrawal)
  • I- infection (UTI, sepsis, pneumonia)
  • R- reduced sensory input
  • I- intracranial (e.g. stroke/ subdural haemorrhage)
  • U- urinary retention
  • M- metabolic (e.g. AKI, hypoglycaemia, hypothyroid, B12, Ca)
28
Q

Signs and symptoms of delirium?

A
  • Acute onset
  • Transient and fluctuating course- lucid intervals
  • Lasts days to months depending on underlying cause
  • Contrast to dementia which is slow and progressive
  • Altered consciousness
  • Inattention and impaired memory
  • Emotional disturbance
  • Sleep cycle reversed
  • Insomnia
  • Disturbing dreams and nightmares
  • Disorientation
  • Hallucinations and illusions (visual hallucinations common vs psychiatric issues which are more commonly auditory)
29
Q

Explain the two types of delirium?

A
  • Hyperactive > agitated, aggressive, wandering, easy to diagnose
  • Hypoactive > withdrawn, apathetic, sleepy, coma, harder to diagnose but twice the mortality rate
30
Q

What are 2 screening assessment for delirium?

A

4AT and Confusion assessment method (CAM)

31
Q

What are the components of the 4AT?

A

ALERTNESS, AMT4 (age, dob, place, year), ATTENTION (months of year backwards), ACUTE CHANGE OR FLUCTUATING COURSE

32
Q

What are the components of CAM?

A

acute change in mental status and fluctuating mental status over course of day AND inattention AND 1 of disorganized thinking or altered level of consciousness – can be practically quite difficult to use but is a nice definition of delirium

33
Q

Describe the think delirium time bundle?

A
  • Delirium is often multifactorial so you shouldn’t stop looking just because you have identified one cause
  • Triggers - investigate – manage – engage
  • History and physical exam (neuro is important)
  • NEWS- think sepsis
  • Blood glucose
  • Medication review
  • Pain review
  • Assess for urinary retention and constipation
  • Assess hydration and fluid balance
  • Bloods- FBC, U+E, Ca, LFTs, CRP, Mg, glucose
  • Symptoms and signs of infection
  • ECG
  • Imaging depends on findings
34
Q

Management of delirium?

A

Treat underlying causes

Manage environment and provide support:

  • Educate staff
  • Reality orientation: communicate, clock, calendar in room
  • Correct sensory impairments: glasses and hearing aids
  • Bright side room with unnecessary noise reduced, unsafe objects removed
  • Ensure basic needs are met

Prescribe:

  • Sedating drugs can worsen delirium
  • Alcohol withdrawal- reducing scale BZD
  • Standard antipsychotic used is haloperidol
  • If someone has PD/ LBD can’t give haloperidol so give lorazepam

Review frequently and follow up

May need AWI act or mental health act

35
Q

List some problems caused by constipation?

A
  • Abdominal pain
  • Vomiting/ nausea
  • Rectal discomfort
  • Overflow diarrhea

  • Rectal bleeding from haemorrhoids
  • Delirium
  • Depression
36
Q

List some causes of constipation?

A
  • Low fibre intake
  • Dehydration
  • Opioids and anti-cholinergics
  • Reduced mobility (physically stops people getting to toilet and also moving around helps constipation)
  • Parkinsons
37
Q

Describe assessment of constipation?

A

3 main questions:
1. Frequency of passing stools and what is their normal (should move bowels at least 3 every 3 days)
2. Consistency using Bristol stool chart
3. Any difficulties evacuating/ feeling of incomplete emptying
• Also ask about fluid intake, diet and exercise
• Examination: abdominal examination, rectal examination

38
Q

What are the 2 main groups of laxatives?

A

those targeting hard stool issue

those that are stimulant

39
Q

Give some examples of laxatives that work by targeting hard stool?

A

osmotic laxatives e.g. laxido and lactulose which are both sachets and softener laxatives e.g. docusate tablets

40
Q

Give some examples of stimulant laxatives?

A

Senna (tablet) and biscodyl (tablet)

41
Q

When should you consider rectal preparations for treatment of constipation? What are some examples?

A
  • Consider if really full and unable to pass

* Options: glycerine suppositories, microenemas e.g. microlette, phosphate enemas

42
Q

Who should oxybutynin not be used in?

A

should not be used in elderly due to increased risk of falls - should use solifenacin, tolteridone or mirabegron instead
(for urge incontinence)

43
Q

Bone protection for patients who are starting long term steroids ______

A

should start immediately

44
Q

Explain what vertebrobasilar insufficiency is and how it would present?

A

Caused by atherosclerosis in vertebrobasilar arteries. The insufficiency is exacerbated by patient extending their neck. Often results in falls. Patient is elderly has falls, and gets dizzy on extending their neck.

45
Q
