Health State Utility (HSU): A Key Metric in Health Technology Assessment

Health state utility (HSU) is a crucial metric that quantifies the influence of a particular health condition on an individual's overall well-being, usually depicted on a scale ranging from 0 to 1. Within the realm of health technology assessment (HTA), HSU plays a vital role in computing quality-adjusted life years (QALYs). QALYs enable the evaluation of the efficacy of a given treatment or medical technology by taking into account both the duration and value of HSU across various health states.
