Quality dying: An approach to ICD deactivation in the hospital setting

In Canada, cardiovascular disease is the second most common cause of death. A subset of these patients will require a cardiovascular implantable electronic device (CIED). An estimated 200 000 Canadians are living with a CIED. CIEDs can improve life and prevent premature death. However, when patients reach the end of their lives, they can pose a challenge. An example of which is a painful shock delivered from an implantable cardioverter defibrillator (ICD) for an arrhythmia in a dying patient. Receiving a shock at the end of life (EOL) is unacceptable in an age when we aim to ease the suffering of the dying and allow for a comfortable death.

As a quality standard of practice, all clinicians are expected to engage in EOL conversations in patients requiring CIED deactivation. Due to the potential discomfort of an ICD shock, specific conversations about deactivation of an ICD are encouraged. A process improvement approach was developed by our hospital that included an advance care planning simulation lab, electronic documentation and a standardized comfort measures order set that includes addressing the need for ICD deactivation at EOL.

EOL conversations are complex. Health care providers have been equally challenged to have conversations about ICD deactivation. Standardization of the process of ICD deactivation ensures an approach to EOL which respects the individuality of patients and promotes quality dying.

Our hospital is committed to assisting clinicians to provide quality care by improving conversations about EOL care. On the basis of a synthesis of existing literature, we describe the importance of and the ideal process for having EOL conversations in patients about ICD deactivation at the EOL.
