What is palliative care?
Looking after people with incurable diseases, relieving their suffering and supporting them through difficult times.
53
What are the principles of palliative care?
Improve the QoL of pts and families with terminal illness by preventing and relieving suffering by identifying and relieving pain and other physical, psychosocial spiritual etc problems. Helps regard dying as a normal process, neither hastens nor postpones death, integrates psychosocial and spiritual care, is a support system to allow patients to live as actively as possible up to death and helps the family cope with bereavement.
54
Define end of life care
Enables the supportive and palliative care needs of the pt and family to be identified and met throughout the last phase and into bereavement including management of pain, symptoms and psychosocial and spiritual aspects.
55
Define supportive care
Care helping the pt and family to cope with their condition and its treatment from pre diagnosis through to death and bereavement.
56

63
What is scarcity?
Central problem addressed by the discipline of economics- resource scarcity.
The purpose behind economic analyses- to help decision makers faced with choices concerning resource scarcity.
64
What is a normative economic stance?
Economic analyses indicate the nature of the resource allocation decision that ought to be followed if certain objectives are to be achieved.
65
What is a positive economic stance?
Economic analyses seek to predict observable factors and so provide information on the likely costs and benefits associated with alternative courses of action.
66
What is opportunity cost?
The value of resources forgone by choosing to deploy resources in one way rather than in their best alternative use.
67
What is technical efficiency?
Producing output in the best way possible without wasting resources, meeting a given objective at the least cost
68
What is allocative efficiency?
Producing the pattern of output that best satisfies the pattern of the consumers' wants or needs
69
What are the key objectives for economic analysis?
To promote the efficient use of health care resources
| To ensure the maximum total benefit is derived from the finite resources available
70
Define economic evaluation
A comparative analysis of alternative courses of action in terms of both costs and consequences
71
What are the outcomes of cost effectiveness analysis?
Must choose one outcome- lives saved or increased survival
72
What are the outcomes of cost utility analysis?
Must consider QoL and QALYs
73
What are the main types of economic evaluation?
```
Cost consequence analysis
Cost effectiveness analysis
Cost minimisation analysis
Cost utility analysis
Cost benefit analysis
```
74
What is the incremental approach to economics?
Would answer- what is the difference in costs and the difference inconsequences of option A compared to option B
75
What is marginal benefit?
Increasing in benefit as a result of increasing production by one additional unit.
76
What is marginal cost?
Increasing in cost as a result of increasing production by one additional unit.
77
What is the incremental cost effectiveness ratio?
ICER= (difference in cost)/(difference in consequence)
78
What is cost effectiveness analysis?
Results in terms of cost per unit effect, can address technical efficiency questions. Decision rule is dominance or CE ratio
79
What is cost utility analysis?
Outcomes in QALYs gained
Combine life years and QoL
Results in cost per additional QALY gained
Can be used to compare across treatment areas
Decision rule- dominance or CU ratio
80
What needs to be identified in an economic health perspective?
Relevant costs and outcomes these depend on perspective of analysis-
Health service
Public sector
Patient
Society
Depends on type of economic evaluation- cost effectiveness analysis, cost utility analysis
81
What outcomes are looked at?
Clinical outcomes, measured in natural units, proxy outcomes, condition specific measures, and generic measures- life years gained
82
What are the advantages and disadvantages of clinical outcomes?
Advantages- part of a clinical study, easily understood/ transparent to clinicians/ decision makers
Limitations- lack of comparability across different disease areas, what does the unit actually mean?
What happens if there's more than one outcome?
83
If there are multiple outcomes with high or low cost and large or moderate impacts in QoL, what happens?
Valuing health- QALYs combine length and quality of life into one unit, weight life years and look at cost per QALY
84
What is a QALY?
Combines length and quality of life, max value = 1, used to weight life years. QALY = sum(length of life) x QoL
85
How are QALYs calculated?
Prognosis with treatment - Prognosis without treatment= total gain in QALYs.
86
Where does the information (for QALYs) come from?
Life years- life tables and literature
QoL- value judgement
- questionnaires with predetermined weights
- direct measurement from health state description
- published values in literature
