When assessing new tests and biomarkers in clinical trials is costly and time consuming, model-based analysis may be valuable to assess (cost‑)effectiveness and budget impact. When the timing of tests can be varied, model-based evaluation of only a limited number of timing strategies is suboptimal. However, evaluation of all possible strategies is often computationally infeasible. This presentation will illustrate the advantages of using a meta-model to optimize test timing, in a case study on screening for colorectal cancer including colonoscopy capacity constraints.
