is the Health Utilities Index (HUI®)?
Uses of HUI®
a system for measuring health status,
health-related quality of life, and producing utility scores. For a schematic of the HUI system click Components.
generic, preference-scored, comprehensive,
based on explicit conceptual framework
of health status and health-related quality of life
there are 3 versions of HUI®:
each version includes a health status
classification system and formula for calculating utility scores.
HUI2 describes 24,000 unique health states and HUI3 describes 972,000 unique health states.
scoring formulas are well grounded in
theory and based on preference data from community surveys.
conceptual and measurement properties
described in numerous papers published in peer-reviewed scientific journals
to date over 300 investigators have
used HUIR in a wide variety of studies in over 20 countries world-wide.
more than 300,000 subjects have been
assessed using HUI.®
available in more than 35 languages world-wide (see LANGUAGES for more details).
available in traditional paper/pencil format suitable for self-administration or interviewer-administration (remote telephony or face-to-face). Either format is suitable for adaptation to computer/web-based application.
