Removing life support: motivations, obligations. An opinion on NCCB Committee for Pro-Life Activities' statement on artificial hydration and nutrition.

In April 1992 the Committee for Pro-Life Activities of the National Conference of Catholic Bishops issued a resource paper titled "Nutrition and Hydration: Moral and Pastoral Reflections." At best, this document and its conclusions may be viewed as a pastoral statement, offering some tentative reasoning and conclusions to be considered in cases that concern the use of medically assisted nutrition and hydration. When discussing the question, is the withholding or withdrawing of medically assisted hydration and nutrition always direct killing? the document applies two principles--"no reasonable hope of benefit" and "involving excessive burdens." The document's crucial part is its admission that artificial hydration and nutrition may be removed without the intention of causing death, and that "this kind of decision should not be equated with a decision to kill or with suicide." The committee assigns decision-making responsibility to patients, families, and healthcare professionals, but continues its discussion for 20 pages and offers cautions conclusions concerning removal of such therapy. Two assumptions seem to underlie the document's overly cautious conclusions, the first being that mere vegetative function mandates continued life support. The first assumption overemphasizes the value of physiological functioning insofar as the purpose of human life is concerned. It also is contrary to the goal of medicine, which envisions restoration of cognitive-affective function as an element of successful therapy. The second assumption is that withdrawal of artificial hydration and nutrition from persons in PVS may lead to euthanasia. But mandating the continuation of nonbeneficial therapy simply because it prolongs physiological function seems to lead people to favor euthanasia rather than reject it.(ABSTRACT TRUNCATED AT 250 WORDS)
