Study Notes
Making Effective Comparisons
- Comparisons should encompass all relevant options to ensure a thorough analysis.
- Variations in current practice may lead to different outcomes or interpretations.
- Multiple new interventions may exist, requiring careful assessment against each other.
- Interventions may also have different applications, which can influence their effectiveness.
Cost Considerations
- Selecting the cheapest option within a specific class of interventions can lead to savings.
- Results can be distorted if the wrong comparator is used, such as:
- Comparing against a non-cost-effective practice, which can inflate perceived effectiveness.
- Neglecting comparisons with cost-effective practices, resulting in a skewed evaluation.
Incremental Analysis
- Incremental analysis is essential when evaluating three or more options.
- This method helps clarify the additional costs and benefits associated with each alternative.
- Following established rules of incremental analysis can produce more accurate and reliable results in decision-making.
