A normative perspective on discounting health outcomes

Area of Science:

• Health economics
• Decision theory
• Public policy

Background:

• Discounting future outcomes is crucial for policy decisions, particularly in health.
• Existing methods for discounting health outcomes lack consensus on appropriate considerations.
• Current discount rates recommended by public authorities are debated for their ethical implications.

Purpose of the Study:

• To identify and justify appropriate considerations for discounting health outcomes.
• To propose a revised framework for discounting health outcomes based on normative deliberation.
• To determine a maximum appropriate annual discount rate for health outcomes.

Main Methods:

• Normative deliberation on ethical considerations for discounting.
• Analysis of two key factors: catastrophic events and intergenerational equity.
• Calculation of a maximum discount rate based on the identified factors.

Main Results:

• Only two considerations are deemed appropriate for discounting health outcomes: catastrophic events and governmental weighting of current over future constituencies.
• Application of these considerations suggests a maximum annual discount rate of 0.5%.
• This proposed rate is substantially lower than those currently recommended by public authorities.

Conclusions:

• A lower discount rate, capped at 0.5% annually, is ethically justifiable for health outcomes.
• This revised approach addresses limitations in current discounting practices.
• Policy decisions regarding long-term health investments should adopt more cautious discounting methods.
