“…In an analysis of differences in the values for adjacent states, Stalmeier et al (2005) find the differences in TTO values for states either just above or below 0 are at least twice as large compared to the differences between other adjacent states. Further, there are few states in the MVH TTO value that are close to 0 (either SBD or SWD).…”

A uniform Time Trade Off method for states better and worse than dead: feasibility study of the 'lead time' approach SummaryThe way Time Trade Off (TTO) values are elicited for states of health considered 'worse than being dead' has important implications for the mean values used in economic evaluation. Conventional approaches to TTO, as used in the UK's 'MVH' value set, are problematic because they require fundamentally different tradeoffs tasks for the valuation of states better and worse than dead. This study aims to refine and test the feasibility of a new approach described by Robinson and Spencer (2006), and to explore the characteristics of the valuation data it generates. The approach introduces a 'lead time' into the TTO, producing a uniform procedure for generating values either >0 or <0. We used this lead time TTO to value 10 moderate to severe EQ-5D states using a sample of the general public (n=109). We conclude that the approach is feasible for use in valuation studies, and appears to overcome the discontinuity in values around 0 evident in conventional methods.

“…Health states rated worse than dead were anchored to the minus 1 scale by using the formula h i ϭ (x Ϫ t)/t. The term x is the time endured for that health state h i , and t is the life expectancy of ten years [35]. Extreme responses and logical inconsistencies were examined.…”

“…Maximum endurable time (MET) has emerged as an important element of the literature on health states worse than dead (e.g., Dolan and Stalmeier, 2003;Stalmeier et al, 2005). MET refers to the maximum duration for which a health state that is worse than dead in the long-run can be tolerated in the short-run; for example, the individual may value highly a period of time prior to death to deal with premature mortality and to set one's affairs in order.…”

“…1 For example , Stalmeier et al (2005) compared the visual analog scale (VAS) and time tradeoff (TTO) methods for elicitation of preferences from interviews with over 3000 subjects. Using VAS, less than 2% of respondents indicated worse than dead preferences for the three highest ranked EQ-5D states; 45% had worse than dead preferences for the lowest ranked state.…”
