Triage and equality: an historical reassessment of utilitarian analyses of triage.

We distinguish and review aspects of the history of two models of triage: egalitarian and utilitarian. Egalitarian triage is widely and successfully practiced in battlefield medicine, as well as in the emergency room and the ICU. Utilitarian triage has been sporadically practiced and typically collapses under the pressure of public scrutiny. Unfortunately, the two models tend to be conflated, confusing our understanding of the past and confounding our ability to plan for the future.
