CHAPTER 1

1. The total cost of Staphbegone is $12,000 + $1,000/day × 5 days = $17,000. The total cost of Staphbeilln is $4,000 + $1,000/day × 10 days = $14,000. The incremental cost of Staphbegone is therefore $17,000 − $14,000 = $3,000.
2. The incremental cost is $17,000 − $14,000 = $3,000, and the incremental effectiveness is 35 QALYs − 34.5 QALYs = 0.5 QALYs. Therefore, the incremental cost-effectiveness is $3,000/0.5 QALYs = $6,000 per QALY gained.
3. 1,000/375/QALY gained = 2.67 QALYs gained.
4. The mosquito net strategy will purchase $1,000/$846/QALY = 1.18 QALYs. The measles strategy will purchase $1,000/$375/QALY = $2.67 QALYs. The number of QALYs forgone is equal to 2.67 QALYs − 1.18 QALYs = 1.48 QALYs relative ...
