QUALY (Quality – adjusted life years)

  • A measure of disease burden including both:
    • Quality and
    • Quantity of life lived
  • Used mainly for assessing the value for money of a medical intervention i.e. cost – effective analysis for comparing different interventions
  • Based on the number of QUALYs gainedby the intervention
  • Each year in perfect health = 1.0
  • Death = 0.0
  • 1 QUALY = one year of life X one utility value = one year of life lived in perfect health
  • Half a year lived in perfect health is equivalent to 0.5 QUALY = 1 year X 0.5 utility value
