Surveying the Cost-Effectiveness of the 20 Procedures with the Largest Public Health Services Waiting Lists in Ireland: Implications for Ireland's Cost-Effectiveness Threshold

Some cost-effective interventions that have large waiting lists may indicate resource misallocation and the threshold may be too high. An evidence-informed revision of the threshold may require a reduction to ensure it is consistent with its theoretical basis in the opportunity cost of other interventions foregone. A limitation of this study was the difficulty in matching specific procedures from waiting lists with ICER estimates from the literature. Nevertheless, our study represents a useful demonstration of a novel concept of using waiting list data to inform cost-effectiveness thresholds.
