Patient informed choice for altruism.

Respect for persons protects patients regarding their own healthcare decisions. Patient informed choice for altruism (PICA) is a proposed means for a fully autonomous patient with decisionmaking capacity to limit his or her own treatment for altruistic reasons. An altruistic decision could bond the patient with others at the end of life. We contend that PICA can also be an advance directive option. The proxy, family, and physicians must be reminded that a patient's altruistic treatment refusal should be respected.
