摘要

To present a generalized QALY model that incorporates both ongoing projects and extrinsic goals. In the QAL Y model, patients' survival duration is given wait proportional to the quality of health the patient experiences. Medical cost effectiveness studies should incorporate morbidity and mortality consequences into a single measure using QAL Ys. In practice, QAL Ys are elicited by subjectively querying patients, physicians, or community members. A variety of methods are available for this purpose (Refs. 1, 2). Tsevat (Ref. 3) points out that correlation between one's current health and time trade-off for health state is at best modest. Tsevat suggests that a person's willingness or unwillingness to trade away life years or accept a gamble involving life years is more a function of how the person values quality of life than quality of health.
