Table 3 Overview of the health economic evaluation study designs for the assessment of cost-effectiveness efficacy in radiology AI (RADAR-6)
Attribute | Cost-minimization analysis | Cost-effectiveness analysis | Cost-utility analysis |
|---|---|---|---|
Description | Compares costs of technologies (known or assumed to be equally effective) to find the cheapest option | Compares costs and outcomes of different technologies to assess if any health benefits justify costs | Compares costs and outcomes of different technologies to assess if any QALY benefits justify costs |
Key input data | Costs | Costs, health outcomes (such as life expectancy, reduction in blood pressure) | Costs, health outcome in terms of QALYs |
Literature example | CMA of lung nodule management strategy leveraging AI in lung cancer CT screening [49] | CEA of AI-based chest CT analysis for rapid COVID-19 diagnosis and prognosis [50] | CUA of AI support in CT-based lung cancer screening [51] |
