Precedent Autonomy and Surrogate Decisionmaking After Severe Brain Injury

Area of Science:

• Neuroscience
• Medical Ethics
• Clinical Neurology

Background:

• Patients with severe brain injuries may have disorders of consciousness (DoC).
• Surrogate decision-makers guide treatment for these patients.
• Current guidelines prioritize advance directives, substituted judgment, and best interests.

Purpose of the Study:

• To evaluate the efficacy of substituted judgment in preserving patient autonomy for DoC patients.
• To propose an alternative decision-making framework for patients with covert awareness.

Main Methods:

• Ethical analysis of substituted judgment principles.
• Review of clinical criteria for disorders of consciousness.
• Exploration of patient autonomy in the context of changing self-awareness.

Main Results:

• Standard substituted judgment may fail to preserve autonomy in patients with covert awareness.
• These patients may possess evolving values and sense of self.
• Past wishes may not reflect current patient values or experiences.

Conclusions:

• Surrogate decision-making for DoC patients requires adaptation.
• Decisions should consider the patient's present experience and potential for evolving selfhood.
• A shift from past-oriented to present-oriented substituted judgment is advocated.
