Should numbers decide questions about health and life?

Health services must decide which treatments to fund, and they often use calculations of cost and benefit. This question asks whether turning lives into numbers makes such decisions fairer or hides moral choices behind mathematics.

Claims

  • When resources are limited, a transparent calculation treats everyone by the same rule and makes decisions open to challenge.
  • Without numbers, decisions depend on who shouts loudest, which is less fair.

Counterclaims

  • Any formula embeds value judgements, such as how much a year of life in poor health is worth, which mathematics cannot justify.
  • A precise number can make an uncertain, moral decision look objective and settled.

Real-life situations from mathematics

QALYs in the UK

The UK's National Institute for Health and Care Excellence (NICE) uses quality-adjusted life years (QALYs) to compare treatments, and has generally treated a cost of about £20,000 to £30,000 per QALY as a guide to value for money.

Triage during the pandemic

During 2020 some hospitals drew up scoring systems to decide which patients would receive intensive care if beds ran out, prompting public debate about fairness to older and disabled people.
