U-titer: a utility assessment tool.

Abstract

We have developed an automated, modular utility assessment software package called U-titer. The package implements the rating scale, category scaling, standard gamble, chronic and temporary time trade-off methods of assessing patient's preferences, and allows extensive tailoring of each method. In addition to calculating utilities, U-titer records information on the process experienced by the user. It can use information gathered in one module to coordinate another module. Our early experience suggests U-titer assessments are similar to traditional assessments. This software should facilitate both the study of patient's utilities and the study of the assessment methods and their implementation.
