The Standard Gamble (SG) technique is recommended for measurement of individuals'preferences under uncertainty and to express the outcome of different therapeutic choices in utility values to be used in clinical decision analysis and health program evaluation.
The article alerts users of this technique to problems stemming from inappropriate interpretation of results of measurements using the SG method.
We demonstrat inappropriate interpretation of the time dimension at the individual level ; issues stemming from the aggregation of individual utility values measured using different time horizons ; the potential for doble counting of the time preference effect when discounting future quality-adjusted life years (QALYs) ; and problems associated with using the SG technique to measure temporary health states...
An alternative approach to QALYs, the healthy years equivalent (HYE), which incorporates the SG but avoid many of these problems is described.
