The EQ-5D portfolio of health status instruments, EQ-5D-3L, EQ-5D-5L and EQ-5D-Y, is the product of nearly 30 years of development and adaptation.
These instruments have been applied in a variety of health sector settings, in patient-reported outcome exercises, in population health studies, and in health technology assessment.
A wide-ranging programme of research studies is in process to adapt and further develop the EuroQol portfolio.
