Insights
Compassionate deactivation (CD) of ventricular assist device (VAD) support is a common end-of-life option for children, often due to noncardiac issues. Discussions involve both caregivers and medical teams, leading to withdrawal of other life support.
Area of Science:
- Pediatric Cardiology
- Palliative Care
- Medical Ethics
Background:
- Compassionate deactivation (CD) of ventricular assist device (VAD) support is a recognized option for pediatric patients when the burdens of therapy outweigh the benefits.
- VADs are increasingly used in children with end-stage heart failure, necessitating clear end-of-life care protocols.
Purpose of the Study:
- To determine the prevalence, indications, and outcomes of compassionate deactivation (CD) in children supported by VADs at the end of life.
- To analyze the factors contributing to the decision for CD and the process of its implementation.
Main Methods:
- A retrospective review of pediatric VAD cases at a single institution from 2011 to 2020 was conducted.
- Cases were specifically identified as CD, excluding deaths during resuscitation, brain death, or from non-survivable brain injury prior to deactivation.
Main Results:
- Compassionate deactivation (CD) accounted for 58% of deaths among pediatric VAD patients (14 out of 24).
- Indications for CD were multifactorial, including end-organ injury, infection, and stroke, often occurring after a median of 40 days on support.
- CD involved withdrawal of ventilatory and inotropic support in 86% of cases, with death occurring within a median of 10 minutes.
Conclusions:
- Compassionate deactivation (CD) is the predominant mode of death in pediatric VAD non-survivors, frequently driven by noncardiac complications.
- Both caregivers and medical providers initiate CD discussions, highlighting shared decision-making in end-of-life care.
- The process often involves discontinuing other life-sustaining treatments, leading to a rapid decline and death.
Context:
Compassionate deactivation (CD) of ventricular assist device (VAD) support is a recognized option for children when the burden of therapy outweighs the benefits.
Objectives:
To describe the prevalence, indications, and outcomes of CD of children supported by VADs at the end of life.
Methods:
Review of cases of CD at our institution between 2011 and 2020. To distinguish CD from other situations where VAD support is discontinued, patients were excluded from the study if they died during resuscitation (including extracorporeal membrane oxygenation), experienced brain or circulatory death prior to deactivation, or experienced a non-survivable brain injury likely to result in imminent death regardless of VAD status.
Results:
Of 24 deaths on VAD, 14 (58%) were CD. Median age was 5.7 (interquartile range (IQR) 0.6, 11.6) years; 6 (43%) had congenital heart disease; 4 (29%) were on a device that can be used outside of the hospital. CD occurred after 40 (IQR: 26, 75) days of support; none while active transplant candidates. CD discussions were initiated by the caregiver in 6 (43%) cases, with the remainder initiated by a medical provider. Reasons for CD were multifactorial, including end-organ injury, infection, and stroke. CD occurred with endotracheal extubation and/or discontinuation of inotropes in 12 (86%) cases, and death occurred within 10 (IQR: 4, 23) minutes of CD.
Conclusion:
CD is the mode of death in more than half of our VAD non-survivors and is pursued for reasons primarily related to noncardiac events. Caregivers and providers both initiate CD discussions. Ventilatory and inotropic support is often withdrawn at time of CD with ensuing death.
