Introduction & Definition[edit | edit source]
The Quality-Adjusted Life Year (QALY) is a measure of the value and benefit of health outcomes.
Health is definied as a function of two components:
1. length of life
2. quality of life
The QALY is an attempt to combine these two attributes into a single figure/number[1].
Calculation of QALY[edit | edit source]
To calculate the QALY, the following formula can be used; this assumes a utility value (quality of life) between 1 = perfect health and 0 = dead.
