Difficulty: MediumAdvance Directives and End-of-Life Care

Review the clinical situations below. Which ethical principle or legal decision-making standard most appropriately justifies the action taken in each situation?

  • A surrogate declines a feeding tube for an incapacitated patient, stating that the patient previously expressed they would never want artificial nutrition, even though it is not in writing.Substituted judgment standard
  • A legal guardian authorizes a life-saving appendectomy for an adult patient who has had severe intellectual disability since birth and has never possessed decision-making capacity.Best interest standard
  • A palliative care physician administers high-dose continuous intravenous morphine to a terminally ill patient to alleviate severe dyspnea, recognizing it may inadvertently depress respiratory drive.Principle of double effect
  • A physician withholds intubation for a patient with acute respiratory failure because the patient's legally valid Medical Orders for Life-Sustaining Treatment (MOLST) form specifies 'Do Not Intubate'.Explicit advance directive

Answer

The surrogate's reliance on prior verbal statements matches the Substituted judgment standard; the guardian's decision for the never-competent patient matches the Best interest standard; the administration of morphine for dyspnea matches the Principle of double effect; and the adherence to the MOLST form matches the Explicit advance directive.
Surrogate decision-making relies on a strict legal hierarchy: 1) Explicit advance directives (living wills, MOLST) provide direct patient instruction; 2) Substituted judgment requires the surrogate to decide based on what the patient would want based on known values; and 3) Best interest requires maximizing benefit when a patient's wishes are unknown or they never had capacity. Additionally, the principle of double effect is a distinct ethical framework protecting clinicians who provide necessary palliative interventions that may foreseeably hasten death, provided the intent is purely to relieve suffering.

Step-by-Step Solution

1
Analyze the decision-making framework for the patient with prior verbal statements.
The surrogate is using the patient's known values to decide, which aligns with the substituted judgment standard.
When written directives are absent but patient preferences are known, surrogates are legally and ethically obligated to use substituted judgment.
2
Analyze the decision-making framework for the patient with lifelong intellectual disability.
The surrogate must weigh objective benefits and harms, which aligns with the best interest standard.
Patients who have never possessed capacity cannot have their substituted judgment determined, necessitating the best interest standard.
3
Evaluate the physician's administration of morphine causing potential respiratory depression.
This scenario describes an action with both a good intended effect and a foreseeable bad effect, aligning with the principle of double effect.
The clinician's intent is symptom relief, not hastening death, which is ethically permissible under this specific principle.
4
Evaluate the scenario involving the MOLST form.
The physician follows a written medical order, which aligns with an explicit advance directive.
A valid MOLST represents the patient's explicit autonomous choice and supersedes surrogate interpretation.
