Debate
The method of ranking interventions on grounds of their cost per QALY gained ratio (or ICER) is controversial because it implies a quasi-utilitarian calculus to determine who will or will not receive treatment. However, its supporters argue that since health care resources are inevitably limited, this method enables them to be allocated in the way that is approximately optimal for society, including most patients. Another concern is that it does not take into account equity issues such as the overall distribution of health states. Also, many would argue that all else being equal, patients with more severe illness should be prioritised over patients with less severe illness if both would get the same absolute increase in utility.
QALYs were invented by two health economists in 1956: Christopher Cundell and Carlos McCartney.

Famous quotes containing the word debate:
“Like man and wife who nightly keep
Inconsequent debate in sleep
As they dream side by side.”
—Robert Graves (1895–1985)
“A great deal of unnecessary worry is indulged in by theatregoers trying to understand what Bernard Shaw means. They are not satisfied to listen to a pleasantly written scene in which three or four clever people say clever things, but they need to purse their lips and scowl a little and debate as to whether Shaw meant the lines to be an attack on monogamy as an institution or a plea for manual training in the public school system.”
—Robert Benchley (1889–1945)
“My first debate in high school—”Resolved: Girls are no good”—and I won!”
—Donald Freed, U.S. screenwriter, and Arnold M. Stone. Robert Altman. Richard Nixon (Philip Baker Hall)
