Difficulty: HardAdvance Directives and Surrogate Decision Making

Physicians must apply specific ethical frameworks and legal principles when navigating medical decisions for patients who lack decision-making capacity. Match each clinical vignette with the primary legal or ethical standard that dictates the appropriate course of action.

  • A 42-year-old man with a severe traumatic brain injury has his legally appointed sibling making decisions. The patient never discussed his healthcare preferences with anyone prior to the accident.Best interest standard
  • A 79-year-old woman with advanced Alzheimer dementia develops sepsis. Her son declines broad-spectrum antibiotics, citing her repeated past statements that she 'would never want to be kept alive if her mind was gone'.Substituted judgment standard
  • An unidentified pedestrian is brought to the trauma bay unresponsive with a massive epidural hematoma. Immediate neurosurgical evacuation is required to prevent imminent death.Emergency consent exception (implied consent)
  • A 65-year-old man with terminal pancreatic cancer becomes obtunded. His medical chart contains a legally binding form explicitly refusing intubation and cardiopulmonary resuscitation under any circumstances.Execution of written advance directives

Answer

The patient with unknown prior wishes requires the best interest standard. The dementia patient whose son relies on prior verbal statements falls under the substituted judgment standard. The unaccompanied trauma patient falls under the emergency consent exception. The cancer patient with a formal document relies on the execution of written advance directives.
Each standard of decision-making applies to a specific clinical context depending on the availability of a surrogate, the acuity of the illness, and the extent to which the patient's prior wishes are known. The emergency exception allows immediate treatment to save a life when no surrogate is present. The best interest standard is strictly for when a patient's wishes are completely unknown. Substituted judgment is used when a surrogate knows the patient's prior values and makes the decision the patient would have made. Written directives directly dictate care based on the patient's prior competent instructions.

Step-by-Step Solution

1
Analyze the scenario of the 42-year-old man with a traumatic brain injury.
The patient lacks capacity, has a surrogate, but his prior wishes are completely unknown. The appropriate framework is the best interest standard.
When a surrogate has no knowledge of what the patient would have wanted, they must choose the option that provides the highest net benefit to the patient.
2
Analyze the scenario of the 79-year-old woman with dementia.
The surrogate is utilizing the patient's previously expressed verbal wishes to make a decision. The appropriate framework is the substituted judgment standard.
Substituted judgment involves a surrogate stepping into the shoes of the patient and making the decision the patient would have made, based on their known values.
3
Analyze the scenario of the unidentified pedestrian.
The patient requires immediate life-saving care, lacks capacity, and has no available surrogate. The appropriate framework is the emergency consent exception.
Physicians may provide life-saving treatment without consent in emergencies when the patient is incapacitated and no surrogate is immediately available.
4
Analyze the scenario of the 65-year-old man with pancreatic cancer.
A legally binding written document is present refusing specific treatments. The appropriate framework is the execution of written advance directives.
A valid written directive made by a competent patient takes precedence in guiding care when the patient later loses capacity.
