What is HUI®?
The Health Utilities Index (HUI) is a system for measuring comprehensive health status and health-related quality of life (HRQL). HUI is the product of more than 40 years of research at McMaster University and development by Health Utilities Inc.

A comprehensive health state is described as a combination of levels for various aspects of health including vision, hearing, speech, mobility, dexterity, self-care, emotion, cognition and pain. Each aspect of health has 3 to 6 levels of ability/disability allowing HUI to describe almost one million unique health states. Scoring formulae are based on preference measurements for health states from random samples of the general population in community surveys.

Who Uses the HUI®?
Hundreds of clinicians and researchers around the world as well as major national statistical agencies have used HUI in more than 35 languages and countries world-wide. Clinical areas of interest range from Alzheimer's and arthritis, to diabetes and hip / knee replacement, to heart and lung transplants, to oncology and ophthalmology, to vascular events and herpes zoster, to name just a few.
