Q

Why have patient-based outcomes?

A

Increase in conditions where aim is managing rather than curing
Biomedical tests just one part of the picture
These focus on patient’s concerns
Need to pay attention to iatrogenic effects of care

17
Q

Pros and cons of using qualitative methods to measure HRQoL?

A

Pros

  • gives access to parts other methods don’t reach
  • good for initial look at dimensions of HRQoL - informing development of quantitative instruments.

Cons

  • very resource hungry
  • not easy to use in evaluation
18
Q

Why measure health?

A

Indication of the need for healthcare
Target resources where they are most needed
Assess effectiveness of health interventions
Evaluate quality of health services
Use evaluations effectively so better value for money
Monitor patient’s progress

19
Q

What do quantitative methods rely on?

A

Questionnaires as instruments/scales

20
Q

What do PROMs need to be?

A

Reliable: is the instrument accurate over time? Internally consistent ie if no change in health, score should be the same

Valid: measures what it is meant to (may only be assessing pain and not social aspects)

21
Q

What are features of generic instruments to measure HRQoL?

A

Can be used with any population including healthy people
Generally cover perceptions of overall health
Also has questions on social, emotional and physical functioning, pain and self-care

22
Q

Advantages of generic instruments?

A

Advantages

  • can be used for a broad range of health problems
  • can be used if there is no disease-specific instrument
  • enables comparisons across treatment groups
  • used to detect unexpressed positive/negative effects of an intervention
  • assess health of populations
23
Q

Disadvantages of generic instruments?

A

Less detailed die to generic nature
Loss of relevance - too general?
Can be less sensitive to changes that occur as a result of an intervention
May be less acceptable to patients

24
Q

Give two examples of generic instruments

A

Short form 36-item questionnaire (SF-36)

EuroQoL EQ-5D

25
Q

What is the SF-36?

A

Contains 36 items that assess HRQoL grouped into 8 dimensions
Responses to questions are scored
Scores of each dimension are added together to give a score between 0-100
Dimension scores are not added together to give an overall score - could make interpretation difficult in some cases

26
Q

Advantages of SF-36?

A

Acceptable to people
Takes 5-10 minutes to complete
Good reliability
Responsive to change

27
Q

What are the five dimensions of EuroQoL EQ-5D?

A 
Mobility
Self care
Usual activities
Pain/discomfort
Anxiety/depression
28
Q

What are the three levels of each dimension in the EuroQoL?

A

No problems
Some/moderate problems
Extreme problems

29
Q

Advantages of EuroQoL EQ-5D?

A

Widely used
Good population data available
Well validated and tested for reliability
Particularly suitable for use in economic evaluations

30
Q

What are the types of specific instruments?

A

Disease specific

Site specific

Dimension specific (pain, depression)

31
Q

Advantages of specific instruments?

A

Relevant content
Sensitive to change
Acceptable to patients

32
Q

Disadvantages of specific instruments?

A

Can’t be used on people without disease
Comparison is limited
May not detect unexpressed effects

33
Q

What points should be used to assess the suitability and value of HRQoL instruments?

A

Is there published work showing established validity and reliability?
Is there other published work showing successful use of the instrument?
Is it suitable for your area of interest
Does it adequately reflect patients’ concerns in this area
Is the instrument acceptable to patients
Is it sensitive to change
Is it easy to administer and analyse?
