Conceptual diagram of the cost-effectiveness analysis. Individuals enter the simulation model and are assigned to one of two QOF scenarios. The model estimates the impact of continuing or stopping the QOF on mortality, morbidity and QOF-related cost outcomes. The trade-offs between quality-adjusted life years (QALYs) and costs are evaluated by calculating an incremental cost-effectiveness ratio (ICER) for continuing the QOF.
