How is frailty defined by international consensus?

A

As a medical syndrome with multiple causes and contributors that is characterised by diminished strength and endurance, and reduced physiological function that increases an individuals vulnerability for developing increased dependency and/or death

Q

How were the deficits used in the Rockwood frailty index decided on?

Q

What score is considered to be terminally ill on the Rockwood frailty index?

A

Over 0.42

22
Q

What is the limitation of the phenotypic model and frailty index?

A

Requirement for either detailed measurements or collation of patient data, which can be challenging in clinical settings where more rapid assessment is required

23
Q

What is a solution to the limitations of the phenotypic model and frailty index?

A

The clinical frailty scale

24
Q

What are the categories on the clinical frailty scale?

A
  1. Very fit
  2. Well
  3. Managing well
  4. Vulnerable
  5. Mildly frail
  6. Moderately frail
  7. Severely frail
  8. Very seriously frail
  9. Terminally ill
25
Q

What is considered to be ‘very fit’ on the clinical frailty scale?

A

People who are robust, active, energetic and motivated. These people commonly exercise regularly. They are among the fittest of their age

26
Q

What is considered to be ‘well’ on the clinical frailty scale?

A

People who have no active disease

symptoms but are less fit than category 1. Often they exercise or are very active occasionally. e.g. seasonally

27
Q

What is considered to be ‘managing well’ on the clinical frailty scale?

A

People whose medical problems are well controlled, but are not regularly active beyond routine walking

28
Q

What is considered to be ‘vulnerable’ on the clinical frailty scale?

A

While not dependent on others for

daily help, often symptoms limit activities. A common complaint is being “showed up”, and/or being tired during the day

29
Q

What is considered to be ‘mildly frail’ on the clinical frailty scale?

A

These people often have more
evident slowing, and need help in high order IADLs (finances, transportation, heavy housework, medications). Typically, mild frailty progressively impairs shopping and walking outside alone, meal preparation and housework

30
Q

What is considered to be ‘moderately frail’ on the clinical frailty scale?

A

People need help with all
outside activities and with keeping house. Inside they often have problems with stairs and need help with bathing and might need minimal assistance (cuing, standby) with dressing

31
Q

What is considered to be ‘severely frail’ on the clinical frailty scale?

A

Completely dependent for personal care, from whatever cause (Physical or cognitive). Even so, they seem stable and not at high risk of dying (within-6 months)

32
Q

What is considered to be ‘very seriously frail’ on the clinical frailty scale?

A

Completely dependent, approaching the end of life. Typically they could not recover even from a minor illness

33
Q

What is considered to be ‘terminally ill’ on the clinical frailty scale?

A

Approaching the end of life. This catagory applies to people with a life expectancy <6 month, who are not otherwise evidently frail

34
Q

What evidence of frailty may there be on a physiological level?

A
  • Increased inflammation
  • Elevated insulin and glucose levels in fasting state
  • Low albumin
  • Raised D dimer and alpha1-antitrypsin
  • Low vitamin D levels
35
Q

Is routine testing for the physiological markers of frailty recommended?

A

Not outside research purposes

36
Q

What interventions may be useful in frailty?

A
  • Physical activity
  • Protein-calorie supplementation
  • Vitamin D management
  • Polypharmacy management
37
Q

How can physical activity be encouraged in the elderly?

A

Exercise programmes

38
Q

What exercise programmes in particular can be useful in the frailty?

A

Those focusing on strength and balance

39
Q

What do exercise programmes in frail people result in?

A

Improved muscle strength and functional abilities

40
Q

What is the best current advice regarding exercise to prevent frailty?

A

To incorporate regular strength and balance training into lifestyle from middle age to prevent progression to frailty

41
Q

Describe the role of protein-calorie supplementation in preventing frailty?

A

It may prevent progression to more advanced frailty states, but conclusive data is not yet available

42
Q

What is vitamin D deficiency associated with?

A

Muscle weakness and sarcopenia

43
Q

Describe the role of vitamin D supplementation in frailty?

A

It clearly has benefit in patients who have a vitamin D deficiency, but it’s use outside this context remains controversial

44
Q

Why is polypharmacy important to consider in frailty?

A

It is associated with an increased risk of progression to more advanced frailty states

45
Q

Describe the role of management of polypharmacy in frailty?

A

Definitive RCT evidence is lacking but, given the other benefits of reduction of inappropriate prescribing, this intervention is relatively uncontroversial.

46
Q

Give 3 benefits of reduction in inappropriate prescribing?

A
  • Decreased falls risk
  • Improved cognition
  • Improved compliance
47
Q

Is routine screening for pre-frailty or early frailty undertaken in the UK?

A

No

48
Q

Why is routine screening for pre-frailty or early-frailty not undertaken in the UK?

A

Because treatments to reverse frailty are of uncertain clinical and cost benefit at an individual level

49
Q

Describe the relationship between frailty and dementia?

A

The degree of frailty corresponds with the degree of dementia

50
Q

What are the common symptoms of mild dementia?

A
  • Forgetting details of recent events, but remembering event itself
  • Repeating same question/story
  • Social withdrawal
51
Q

What happens in moderate dementia?

A

Recent memory is impaired, but can remember past life well. They can do personal care without prompting

52
Q

What happens in severe dementia?

A

Cannot do personal care without help
