Ethics, Prognostication, and End-of-Life Care
Prognostication
Prognostication after severe brain injury is uncertain and should be multimodal and delayed - avoid early self-fulfilling prophecies from premature withdrawal. Use clinical exam, imaging, EEG, and biomarkers, and communicate uncertainty honestly. Understand that withdrawal of life-sustaining therapy is a common cause of death after TBI and can bias outcome data.
Ethics and communication
Master the principles: autonomy, beneficence, nonmaleficence, and justice. Understand surrogate decision-making, advance directives, and the difference between withholding and withdrawing care (ethically equivalent). Recognize the importance of goals-of-care conversations, palliative care integration, and cultural sensitivity. Organ donation after brain death or circulatory death raises distinct ethical and logistical issues.
Traps
- Prognosticating too early or from a single modality.
- Confusing "withdrawal of care" with euthanasia or assisted death (they are distinct).
- Ignoring surrogate authority or advance directives.
Rule of thumb
Prognosticate late, multimodal, and with humility; the family's values guide goals of care.
Worked example
A family asks about recovery after severe TBI at 48 h. Explain that early prediction is unreliable, that multimodal assessment over days is needed, and that goals-of-care discussions can proceed without premature withdrawal decisions.
