QALYs, euthanasia and the puzzle of death

Area of Science:

• Bioethics
• Health Economics
• Medical Decision Making

Background:

• Healthcare metrics like the quality-adjusted life year (QALY) are increasingly used in policy and resource allocation.
• Philosophical complexities surrounding death pose challenges when integrated into quantitative health measures.
• The use of QALYs in debates on euthanasia and assisted suicide raises ethical concerns regarding the valuation of life and death.

Purpose of the Study:

• To analyze the conceptual and ethical problems arising from the incorporation of death into healthcare metrics, specifically the QALY.
• To critically evaluate the QALY's utility and reliability in contexts involving comparisons between life-states and death.
• To argue against the use of QALYs in ethical debates concerning euthanasia and assisted suicide due to inherent limitations.

Main Methods:

• Conceptual analysis of the QALY metric and its underlying assumptions.
• Examination of the literature regarding the interpretation of zero and negative QALY values.
• Ethical critique of QALYs' capacity to compare health states with death.

Main Results:

• The QALY metric provides confused and unreliable information when assigning zero or negative values.
• The assumption that QALYs can make meaningful comparisons between life-states and death is philosophically questionable.
• QALYs are derived from preferences about health states, not necessarily about events like dying or actions like killing.

Conclusions:

• The QALY metric's limitations in handling zero or negative values and its apparent recommendation of death render it unsuitable for euthanasia and assisted suicide debates.
• The ethical debate on end-of-life choices extends beyond the simple preference of death over a life-state.
• The use of QALYs should be restricted to comparing treatment benefits and excluded from discussions involving the valuation of life against death.
