Health Economics Key Concepts Flashcards
Comparison of 2 or more alternative courses of action in terms of both their costs and their consequences
Economic evaluation
How are different types of economic evaluation distinguished?
From how consequences are measured (different units for outcomes)
An economic evaluation that expresses both costs and outcomes of an intervention in monetary terms
Cost Benefit Analysis
In CBA, how are benefits valued?
In monetary terms using valuations of people’s observed or stated preferences
An economic evaluation that compares costs and consequences of different interventions using a single outcome measured in natural units. Interventions are compared in terms of cost per unit of outcome.
Cost Effectiveness Analysis (cost per unit of effectiveness)
An economic evaluation where benefits are expressed as the number of life years saved adjusted to account for loss of quality from morbidity/side effects from intervention.
Cost Utility Analysis
What is the most common measure used in CUAs?
QALY - quality-adjusted life year
A subjective threshold used to determine if the intervention studied is cost-effective and/or should be adopted.
Cost Effectiveness Threshold
Typical cost effectiveness threshold in the UK?
£20,000-£30,000 per QALY
Diagrammatic way of comparing technologies or treatment alternatives.
Cost effectiveness plan
What are the 4 different areas in a cost effectiveness plan?
Quadrant 1 - intervention more effective + more costly than comparator
Quadrant 2 - intervention more effective + less costly than comparator
Quadrant 3 - intervention less effective + less costly than comparator
Quadrant 4 - intervention is less effective and more costly than comparator
The standard intervention (or lack of intervention) against which the intervention under appraisal is compared.
Comparator
The measure of the possible results that may stem from exposure to a preventative or therapeutic intervention.
Outcome
- measures may be intermediate endpoints or they can be final endpoints
What does effectiveness refer to in the context of healthcare?
Clinical effectiveness
A combination of an individual’s physical, mental, and social well-being; not merely the absence of disease.
Health-related quality of life (HRQL)
An index of survival (years gained) that is adjusted to account for the patient’s quality of life during this time.
QALY
Why are QALYs favoured over just years-gained?
QALYs take into account BOTH quantity and quality of life gained
A standard measure for comparing health outcomes for various health conditions taking into account years of life lost due to premature mortality and years of productive life lost due to disability.
DALYs - disability adjusted life years
Average years of life gained per person as a result of an intervention.
Life-years gained (often used in CEAs)
The difference between the present value of cash inflows and the present value of cash outflows.
Net Present Value
The difference in the mean costs in the population of interest divided by the differences in the mean outcomes in the population of interest.
Incremental Cost Effectiveness Ratio (ICER)
If an intervention has higher costs and lower outcomes than an alternative intervention, it is…
Being dominated (by the alternative)
If an intervention has lower costs and higher outcomes than an alternative intervention, it is…
Dominating (the alternative)
Discounting says what about costs and benefits occurring now and in the future?
Costs and benefits incurred today have a higher value than costs and benefits occurring in the future
