Defibrillator Deactivation against a Patient's Wishes: Perspectives of Electrophysiology Practitioners.

Background: Unilateral do-not-resuscitate (DNR) orders (against patient/family wishes) have been ethically justified in cases of medical futility. We investigated whether electrophysiology practitioners believe medical futility justifies unilateral implantable cardioverter defibrillator (ICD) deactivation.

Methods And Results: Email invitations to take an online survey were sent to 1,894 electrophysiology practitioners. A total of 384 responses were collected (response rate 20.6%). Though the sample included respondents from Europe, Asia, Australia, South America, and Africa, the majority were from North America (78%), were academically affiliated (64%), and practiced in an urban setting (67.8%). Deactivation of ICD shock function in agreement with patient wishes and a preexisting DNR were not considered physician-assisted suicide (93.2%, 358/384). However, a majority of the sample responded that it was not ethical/moral for doctors to deactivate ICDs against patients' wishes (77.1%, 296/384) or against family/surrogates' wishes (72.4%, 278/384), even in the context of medical futility. A majority indicated that deactivating ICD shock function is not ethically/morally different than withholding cardiopulmonary resuscitation or external defibrillation in a code (72.7%, 277/381), but was different than deactivating pacing in a pacemaker-dependent patient (82.8%, 318/384). In the classification of interventions, a plurality (43.0%, 165/383) regarded ICDs to be unlike any other intervention. Concerning pacemakers, 50% (191/382) considered them to be like dialysis (a therapy that keeps patients alive).

Conclusions: This international sample of electrophysiology practitioners considered ICD and pacemaker deactivation to be ethically distinct. While ICD deactivation was considered appropriate in the setting of patient/family agreement, unilateral deactivation was not.
