Work out quality adjusted life years instantly with clear inputs, formula shown and shareable results.
Multiplies years of life by a health utility between 0 and 1, and applies the annuity discount factor used in health technology assessment.
QALY
QALYs = years x utility; discounted QALYs = utility x (1 - (1 + r)^-years) / r
They come from instruments such as EQ-5D valued with a national tariff, where 1 is full health and 0 is equivalent to death.
It is the discount rate NICE specifies for both costs and health effects in the UK reference case.
