Evidence of economic evaluation article classification
| Type of economic evaluation | Cost-minimization analysis | Cost-effectiveness analysis | Cost-utility analysis |
|---|---|---|---|
| Evidence of economic evaluation article classification | 1. Total cost of the interventions presented 2. Costs of the interventions presented in the same monetary unit (or currency) 3. Different interventions yielded the same results 4. Cost-minimizing intervention selected as an alternative intervention 5. All expenses related to the interventions considered 6. Indirect comparison between the interventions undertaken if direct comparison was infeasible |
1. Costs of the interventions presented in monetary unit (or currency) 2. Outcomes (effect) measured in natural units 3. Results of the evaluation presented in ICER 4. Cost-effectiveness judged by whether the total cost of the alternative intervention was below the threshold 5. Costs of improving additional unit effect presented under the condition that the effect units of alternative interventions were the same, but the improvement rate differed |
1. Costs of the interventions presented in monetary unit (or currency) 2. Outcomes (effect) measured in QALY 3. Results of the evaluation presented in ICER 4. Cost-utility judged by whether the total cost of the alternative intervention was below the threshold 5. QoL considered in addition to extended lifespan 6. Cost of improving anadditional QALY formed social consensus |
| Illustration of the evidence | Comparison between standard intervention vs. A intervention and standard intervention vs. B intervention | Extended lifespan, drop in blood pressure. Additional expenses per additionally extended lifespan |
Additional expenses per additionally acquired QALY |
ICER: incremental cost-effectiveness ratio, QALY: quality-adjusted life year, QoL: quality of life
aArticles presenting different results between the standard and alternative intervention were classified as “cost analysis.”
