Utilitarian Bioethics

Helping orphans the way you would do it
Utilitarian Bioethics is a very controversial branch of Utilitarian ethics that espouses directing medical resources where they will contribute most to the sum of the number of happy people in the world. It is implicitly used in some healthcare planning decisions, such as the use of Quality Adjusted Life Years (QALYs).

The upsides of Utilitarian Bioethics include reduced suffering and increased medical expediture on other patients.

Downsides include: potential justifications for physicians to kill patients, the uncertainty in measuring 'happiness', and the possibility of classification of many disabled or old people as "nonpersons".
