Cost-minimization | Drugs are equal | Only cost is considered. For example, choosing which ACEI goes on the formulary | |

Cost-benefit | Used to evaluate programs, not drugs | Outcome expressed as benefit: cost | |
Cost-utility | Looking at life years | Usually expressed in QALYs (quality-adjusted life years) |
