Healthy Years Equivalent

Definitions

Health Economics

  • The number of years of perfect health followed by instantaneous death that has the same utility as a profile of actual health states over an expected lifetime. The experimental method used to derive preference-based values of health states for use in cost-effectiveness and cost-utility analyses employs both the standard gamble and the time trade-off methods. The HYE was invented in order to overcome disquiet over some of the assumptions needed to base quality-adjusted life-years on individual preference s. In particular, HYEs do not depend on 'adding up' QALYs ascribed to periods within an overall period of time (e.g. a life-time); they depend instead on an individual's ability to ascribe a health value to the profile of health states across the whole time period.
