Table 1 Cost-Utility Example

From: Problems and solutions in calculating quality-adjusted life years (QALYs)

TREATMENT COST OUTCOMES (QALYs*)
A $1500 3.6
B $1000 1
Increment (of A over B) $500 2.6
Incremental cost/Incremental Outcome $500 / 2.6 QALYs = $192.31 per QALY gained
  1. *(3.6 QALYs = 4 years × 0.9 Units of Utility); (1 QALY = 2 years × 0.5 Units of Utility)
