TL;DR: This paper shows how rank-dependent utility theory, a newly developed theory in decision science, can explain the main violations of expected utility and provides a means for correcting the SG method and for improving the assessments of quality-adjusted life years for medical decisions in which there is uncertainty about outcomes.
Abstract: Methods for determining the form of utilities are needed for the implementation of utility theory in specific decisions. An important step forward was achieved when utility theorists characterized useful parametric families of utilities, and simplifying decompositions of multiattribute utilities. The standard development of these results is based on expected utility theory which is now known to be descriptively invalid. The empirical violations of expected utility impair the credibility of utility assessments. This paper shows, however, that parametric and multiattribute utility results are robust against the major violations of expected utility. They retain their validity under non-expected utility theories that have been developed to account for actual choice behavior. To be precise, characterizations of parametric and multiattribute representations are extended to rank dependent utility, state dependent utility, Choquet expected utility, and prospect theory. Added after publication: Our Theorems 1 and 2 were essentially already given as Theorems 4 and 3, respectively, in Udo Ebert (1988), "Measurement of Inequality: An Attempt at Unification and Generalization," Social Choice and Welfare 5, 147-169. We discovered this only after publication.

TL;DR: There is no consensus among surgeons regarding the follow-up of patients with colorectal cancer and Randomised controlled trials comparing different follow- up strategies and cost-effectiveness analyses are needed to identify groups of patients that will benefit most from follow-ups.
Abstract: But : Preciser les modalites de surveillance des cancers colorectaux operes aux Pays-Bas et les comparer a celles d'autres pays. Type d'etude : Enquete par courrier. Provenance : Tous les departements de chirurgie des Pays-Bas. Principaux criteres de jugement : L'attitude des chirurgiens vis a vis de la detection et du traitement des recidives des cancers colorectaux. Resultats : Sur les 139 questionnaires envoyes, 136 (98%) ont ete completes. La detection des recidives locales ou de tumeurs metachrones faisait appel a l'histoire de la maladie, a l'examen clinique et a la coloscopie dans 90% des hopitaux. L'attitude vis a vis de la detection des metastases hepatiques et pulmonaires et des recidives regionales variait considerablement d'un hopital a l'autre. Des constatations similaires ont ete faites dans les etudes de suivi provenant d'autres pays. Conclusions : Il n'existe pas de consensus parmi les chirurgiens en ce qui concerne le suivi des patients ayant un cancer colorectal. Des essais randomises, controles comparant differentes modalites de surveillance et des analyses de cout sont necessaires pour identifier les groupes de patients suceptibles de beneficier le plus de la surveillance. L'identification de ces patients devrait aboutir a un meilleur consensus entre les chirurgiens.
