EuroQol Protocols for Time Trade-Off Valuation of Health Outcomes
The time trade-off (TTO) valuation technique is widely used to determine utility values of health outcomes to inform quality-adjusted life-year (QALY) calculations for use in economic evaluation. Protocols for implementing TTO vary in aspects such as the trade-off framework, iteration procedure and its administration model and method, training of respondents and interviewers, and quality contro...
متن کاملLearning effects in time trade-off based valuation of EQ-5D health states.
OBJECTIVES In EuroQol five-dimensional questionnaire valuation studies, each participant typically assesses more than 10 hypothetical health states by using the time trade-off (TTO) method. We wanted to explore potential learning effects when using the TTO method, that is, whether the valuations were affected by the number of previously rated health states (the sequence number). METHODS We in...
متن کاملAutomated current health time-trade-off assessments in women's health.
OBJECTIVE To motivate the role for preference assessment in women's health and to report pilot data addressing the performance of automated time-trade-off (TTO) valuations of current health, which were developed to estimate quality-adjusted life years (QALYs) in the women's health setting. METHODS Values for current health relative to perfect health and death were assessed using an annual tim...
متن کاملLogical inconsistencies in time trade-off valuation of EQ-5D-5L health states: Whose fault is it?
INTRODUCTION Inconsistency in the time trade-off (TTO) task in EQ-5D-5L occurs when a respondent gives a higher value to a logically worse health state, the occurrence of inconsistency compromises the quality of the data. It is not yet clear which factors are associated with individual level inconsistency. Relating inconsistency to the characteristics of the respondent, interviewer, and the int...
متن کاملA New Heuristic Algorithm for Time-cost Trade-off Problem Taking into Account Monetary Value
Time-cost trade-off is one of the most important subjects in project management and of interest to contractors. The goal of time-cost trade-off is sensivity analysis of project costs to changes in activity duration in order to obtain the best combination of activity duration decrease, in a way that the sum of project costs is minimized. In the heuristics presented in this area, time crashing is...
