The Importance of Capacity Assessment

Arises frequently in the ED, even when not formally recognized
Carries both legal implications and ethical weight
Failure to appropriately assess capacity can result in:
- Forced treatment without justification
- Missed opportunities to respect autonomy
- Increased risk of litigation and poor patient outcomes

Capacity is:
- Decision-specific: varies based on the medical choice at hand
- Time-specific: can fluctuate due to medical conditions, intoxication, delirium
Distinct from competency, which is a legal determination
Relies on a patient’s ability to:
- Understand relevant information
- Appreciate the consequences
- Reason through options
- Communicate a clear choice

Intoxicated patient with head trauma refusing CT
- Unreliable neuro exam
- Potentially time-sensitive intracranial injury
Elderly patient with sepsis refusing admission due to caregiving responsibilities
- Balancing autonomy vs. beneficence
Patient with gangrenous diabetic foot refusing surgery
- Demonstrates logic and consistency despite high-risk decision

Understanding
- Can the patient explain:
- Their condition
- Recommended treatments
- Risks and benefits
- Alternatives and outcomes?
Sample prompts:
- “What are the options for your situation?”
- “What might happen if we do nothing?”
Appreciation
- Does the patient grasp the personal relevance of the information?
- Sample prompts:
  - “Why do you think we’re recommending this?”
  - “How do you think this condition could affect you?”
Reasoning
- Can the patient logically explain their choice?
- Must demonstrate a rational process, even if the outcome seems unwise
- Sample prompts:
  - “What factors are you considering in making this decision?”
  - “What led you to this conclusion?”
Choice
- Is the patient able to clearly communicate a decision?
- Any modality acceptable: verbal, written, gestural
- Sample prompts:
  - “We’ve discussed several options. What do you want to do?”
  - “Have you decided what option is best for you?”

Time Pressure

Capacity assessments can be time-consuming
Yet, patients leaving AMA without proper evaluation are at higher risk:
- ↑ 30-day mortality
- ↑ 30-day readmission

Communication Barriers

Ethical Dilemmas

Clearly document:

The patient’s understanding, appreciation, reasoning, and choice
Information delivered:
- Condition
- Treatment recommendations
- Alternatives and risks
Patient’s responses and logic
Witnesses to the conversation
Any discharge instructions, including:
- Follow-up plans
- Prescriptions provided
- Return precautions

Also document:

If patient refused treatment, document:
- That risks and benefits were clearly explained
- That refusal was voluntary
If treatment was administered despite objection:
- Document rationale for presumed lack of capacity
- Legal/ethical justification for action
- Involvement of other services (e.g., Psychiatry, Risk)
