Legal and ethical issues in dementia care

Decisional Capacity - Can They Choose?

• Decisional Capacity: A clinical determination of a patient's ability to make a specific medical decision. It is task-specific and can fluctuate, unlike competency, which is a legal state.
• Requires the ability to:
  • Communicate a choice
  • Understand relevant information
  • Appreciate the situation and its consequences
  • Reason about treatment options

⭐ Capacity is not global. A patient may have capacity for one decision (e.g., naming a proxy) but not another (e.g., complex surgery). It must be assessed for the specific decision at hand.

Advance Directives - Planning Ahead

• Legal instruments allowing individuals to state future medical care preferences before losing decision-making capacity.
• Living Will:
  • Outlines desired or rejected treatments (e.g., mechanical ventilation, tube feeding).
  • Less flexible; cannot cover all future scenarios.
• Durable Power of Attorney for Healthcare (DPOAHC):
  • Appoints a healthcare proxy/agent to make decisions.
  • More flexible and broadly recommended.
• Physician Orders for Life-Sustaining Treatment (POLST):
  • Medical orders for current treatment for seriously ill patients.
  • Specifies CPR, medical interventions, and feeding.

⭐ A DPOAHC is often preferred over a living will because it provides a designated person (agent) who can interpret the patient's wishes in unforeseen clinical situations, offering greater flexibility.

Safety & Reporting - Driving Dilemmas

• Core Conflict: Balancing patient autonomy vs. the physician's ethical duty to protect the public. Public safety often takes precedence.
• Clinical Assessment: Crucial for determining risk.
  • In-office: MMSE, MoCA, Clock-Drawing Test, Trail Making Test Part B.
  • History from family/caregivers is vital.
  • Gold Standard: Formal on-road driving evaluation.
• Management Protocol:
  • Counsel patient and family on safety risks.
  • Recommend driving cessation if impairment is found.
  • Document all conversations and recommendations meticulously.

⭐ Most states legally protect physicians from liability when they report a potentially unsafe driver to the DMV in good faith. Reporting laws (mandatory vs. permissive) vary by state.

Vulnerability Shield - Elder Abuse

• Definition: Any intentional act or failure to act by a caregiver or another person in a relationship involving an expectation of trust that causes or creates a risk of harm to an older adult.
• Risk Factors in Dementia:
  • Patient: Cognitive impairment, dependency, behavioral disturbances.
  • Caregiver: Stress, burnout, substance abuse, financial dependency on the elder.
  • Social: Isolation, lack of support.
• Clinical Indicators:
  • Unexplained injuries (e.g., bruises in unusual patterns, spiral fractures).
  • Poor hygiene, pressure ulcers, malnutrition, dehydration.
  • Sudden changes in finances or will.
  • Fearful or withdrawn behavior.

⭐ Mandatory Reporting: Physicians are mandated reporters. If elder abuse is suspected, a report must be made to the local Adult Protective Services (APS) agency. This is a legal duty that overrides patient confidentiality; consent is not required.

High-Yield Points - ⚡ Biggest Takeaways

• Decision-making capacity is task-specific and can fluctuate; it is not an all-or-nothing judgment.
• Advance directives (e.g., living will, durable power of attorney) are crucial for upholding patient autonomy.
• When a patient lacks capacity, decisions fall to a designated surrogate or next of kin.
• Physicians have an ethical duty to address driving safety, which may require reporting to the DMV.
• Maintain a high suspicion for elder abuse (financial, physical, neglect) in this vulnerable population.
