The Load Model: An alternative to QALY

QALYs (Quality Adjusted Life Years) are widely used in economic evaluation in health care, but have been criticised. The Load Model is an alternative model. Load is the average annual weight attributed to morbidity and mortality over a defined period, using weightings based on preference judgements. In a worked example, the morbidity component is higher in the Load model than in the QALY model, based on otherwise identical assumptions. When comparing alternative outcomes, there are also large differences between the two models. Given the role of the QALYs in economic evaluation, the implications of an alternative, which generates such different results, warrants further exploration.
