RT Journal Article SR Electronic T1 The ethical and legal implications of deactivating an implantable cardioverter-defibrillator in a patient with terminal cancer JF Journal of Medical Ethics JO J Med Ethics FD BMJ Publishing Group Ltd and Institute of Medical Ethics SP 538 OP 540 DO 10.1136/jme.2006.017657 VO 33 IS 9 A1 England, Ruth A1 England, Tim A1 Coggon, John YR 2007 UL http://jme.bmj.com/content/33/9/538.abstract AB In this paper, the ethical and legal issues raised by the deactivation of implantable cardioverter-defibrillators (ICDs) in patients with terminal cancer is considered. It is argued that the ICD cannot be well described either as a treatment or as a non-treatment option, and thus raises complex questions regarding how rules governing deactivation should be framed. A new category called “integral devices” is proposed. Integral devices require their own special rules, reflecting their position as a “halfway house” between a form of treatment and a part of the body. The practical problems faced by doctors working in palliative medicine with regard to the deactivation of ICDs are also considered.
