Abstract
Medical futility is a recent, complex bioethical issue. There is disagreement about how futility should be defined and who should be involved in futility decisions when an impasse exists between the patient/family and the physician. Bioethical discussions about Quinlan and Cruzan of the past have been replaced with the Wanglie, Baby K, and Linares cases-all of which involved critical care settings. Nurses often are involved in the debate and encounter ethical conflicts. Cost-containment, managed care, scarce resource allocation, and care due the elderly have fueled the debate. Key issues and their importance for critical care nurses will be reviewed.
