Abstract

Purpose. To evaluate the validity of standard gamble (SG)utilities, by comparing utilities with decision-making behavior in a group of lung transplant candidates facing a risky health decision. Methods. The authors elicited SG utilities for current health from 57 transplant candidates. They assessed the concordance between utility scores and patients' self-reported readiness to be placed on the transplant waiting list(“listed†). Because transplantation represents a real-life gamble with a short-term survival probability of 85%, the authors defined their minimum validity criterion as utility for current health 0.85 in transplant-ready patients. Results. Utilities were significantly higher in patients who were not ready for listing ( n = 22, median utility = 0.79, range 0.06-1) than in those who were ready or listed ( n = 35, median utility = 0.50, range 0-0.85, P
