The measurement of utility in multiphase health states.
To examine the validity of the additive quality-adjusted life year model used to evaluate a multiphase health state, data from a pilot study of mammography were used to determine whether the values assigned to a multiphase postmastectomy health state could be estimated from a combination of the independently rated constituent health state values. The results suggest that they cannot.
