Withdrawal of Life-Sustaining Treatment and Surrogate Decision-Making
A 67-year-old woman with a severe TBI after a fall is 10 days into an ICU course. She has a tracheostomy, is ventilator-dependent, and has a poor prognosis: her physicians estimate a low likelihood of meaningful recovery but acknowledge uncertainty. She has no advance directive. Her adult son is her healthcare proxy and wants 'everything done.' Her adult daughter, who lives out of state, says her mother 'would never want to live like this' and wants withdrawal of the ventilator. The two siblings are in conflict. The patient's primary care physician recalls that she once said she 'didn't want to be a burden' but never completed a document.
1. How do you approach the conflict between the siblings and the surrogate decision-making standard?
Read the worked answer
The surrogate's role is to make the decision the patient would have made, using substituted judgment where the patient's values are known, and best interests where they are not.
- Identify the legal decision-maker: the son is the designated proxy and generally has priority. The daughter's views should be heard but do not automatically override the proxy.
- Elicit the patient's values: the PCP's recollection ('didn't want to be a burden') is a starting point but is ambiguous - it may reflect a desire to avoid dependency, or may simply reflect modesty. Explore with both children: what did she say about quality of life, independence, and what mattered to her? Did she ever discuss specific scenarios?
- Address the conflict: hold a structured family meeting, acknowledge both perspectives, clarify that the goal is to represent the patient, not to resolve sibling differences. Consider ethics consultation and, if needed, mediation.
- Acknowledge prognostic uncertainty: be honest that the outcome is uncertain and that time-limited trials of treatment are a legitimate option. A time-limited trial with defined milestones can bridge disagreement without forcing an immediate decision.
- Know the legal framework: if conflict persists, the institution's ethics committee and, in some jurisdictions, courts or statutory mechanisms may be involved. Document everything.
2. The son asks whether 'everything' includes a feeding tube and long-term ventilation. How do you counsel the family and what process do you propose?
Read the worked answer
Counsel that 'everything' is not a single choice: treatments can be considered individually, and the goal is to provide care consistent with the patient's values and realistic outcomes.
- Clarify the trajectory: explain the current status, the range of possible outcomes, and the burdens of prolonged ventilation and feeding tubes.
- Separate decisions: ventilation, tracheostomy care, feeding tube, and resuscitation can be addressed separately.
- Propose a time-limited trial: set specific milestones (e.g., neurologic improvement, ability to wean, interaction) over a defined period (e.g., 2-4 weeks), with a scheduled reassessment. This respects the son's desire to continue while giving the daughter a structured path.
- Involve the team: palliative care, ethics consultation, social work, and chaplaincy as appropriate. Provide written information and interpreter services if needed.
- Document: record the family meeting, the patient's known values, the decision-making standard used, and the plan for reassessment.
The clinician's role is to guide, educate, and support - not to pressure - while ensuring decisions are made in the patient's interests and within the legal framework.
