Quality of life: the contested rhetoric of resource allocation and end-of-life decision making.

The term"quality of life" has a long history in the bioethics literature. It is usually used in one of two contexts: in resource allocation discussions in the hope of arriving at an objective measure of the worth of an intervention; and in end-of-life discussions as a concept that can justify the forgoing of life-sustaining treatment. In both contexts, the term has valid uses as it is meant to measure the efficacy of a treatment.
