How the value of Quality-Adjusted life years (QALY) changes with age (IMAGE)
Caption
This plot shows how the value of a QALY change as an individual gets older according to four different scenarios. Each scenario illustrate that a possible trajectory of an individual’s quality of life (QoL) over their lifetime. For example, scenario 1 contemplates a slow but steady decline in QoL from age 50 onwards. Meanwhile, scenario 4 contemplates a very pronounced decline at the age of 60 before stabilizing into a slow and steady decline afterwards.
