Case: Life on a Machine - Mrs. Mythili (78F)

1. Extent of Patient Autonomy

• She did not want to be intubated or kept alive on a machine
• She said "I don't want to depend on a machine to live"
• She raised this concern across multiple visits, not just once (showing it was not a momentary emotional reaction)

Autonomy is not absolute but must be given significant weight, especially when the patient's wishes are consistent, repeated, and clearly expressed.

2. Elements in Decision Making: Competency vs. Capacity

• She is not legally incompetent - no court has declared her so
• Her decision-making capacity is fluctuating - she is sometimes lucid, sometimes not (delirium likely secondary to pneumonia + hyponatremia)
• When lucid, she may retain capacity for this specific decision
• A proper bedside capacity assessment should be done during a lucid interval using the four elements:
  1. Understanding - does she understand the diagnosis?
  2. Appreciation - does she appreciate consequences of refusing?
  3. Reasoning - can she weigh options?
  4. Expression - can she communicate a choice?

The doctor should not simply assume she lacks capacity because she is "drowsy and restrained." Capacity assessment during lucid periods is the correct approach.

3. Surrogacy in Decision Making

1. Patient's own previously stated wishes (advance directive / living will)
2. Legal surrogate / healthcare proxy
3. Closest family member

• Mrs. Mythili has no documented advance directive (the doctor failed to help her create one)
• The son is the only family member present
• However, surrogate decision-making must follow the substituted judgment standard - "What would the patient have wanted?" - NOT what the surrogate personally wants

The son can be informed and involved, but cannot override the patient's own clearly expressed prior wishes. His role is to help reconstruct her wishes, not substitute his own.

4. Autonomy vs. Beneficence

• Autonomy: Mrs. Mythili's repeated, consistent refusal of ventilatory support and machine-dependent life
• Beneficence: The duty to act in the patient's best interest - which may include treating a potentially reversible pneumonia

• Her wishes were repeated and clear
• She is elderly, isolated, had a poor quality of life (healed badly from hip fracture, lives alone)
• The pneumonia may or may not be reversible
• Forcing treatment violates her dignity and prior expressed values

• Delirium may be masking her true current wish
• Pneumonia could be treatable - this may not be a terminal situation
• She has not been formally assessed for capacity during a lucid interval

5. How Much Do Family Wishes Count?

• Sources of information about the patient's values and prior statements
• Emotional support during decision-making
• Surrogate decision makers when there is no advance directive

• They conflict with the patient's own expressed wishes
• They are driven by guilt, grief, or personal interests rather than the patient's best interest
• The patient had capacity and already made a decision

• Was largely absent (lives in the US, visits once a year)
• Was not involved in her healthcare discussions
• Is reacting emotionally ("everything possible")
• Had no knowledge of her stated health preferences

Family wishes matter and deserve compassionate engagement, but they do not override patient autonomy. The son should be counseled empathetically about his mother's values and prior expressed wishes.

6. Legal, Ethical, and Social Aspects of "Do Not Resuscitate" (DNR)

• A valid DNR order must be documented by the treating physician after a discussion with the patient (when capacitated) or with surrogate
• In most jurisdictions, a verbal statement to the doctor without a signed form has no binding legal force - this is why the earlier missed opportunity to document her wishes matters
• A DNR does not mean "do not treat" - it only refers to CPR/resuscitation

• A DNR respects patient autonomy and avoids non-beneficial, burdensome interventions
• It aligns with the principle of non-maleficence - preventing harm from futile aggressive measures
• It is ethically supported when consistent with the patient's values and prognosis
• Withholding CPR from a patient who expressed not wanting it is ethically justified

• In many cultures (especially Indian context here), death and end-of-life decisions carry significant social stigma
• Families often feel guilty or pressured to "do everything"
• The son's reaction is socially understandable but must be managed with sensitive counseling
• There is a lack of awareness about advance directives and palliative care in many societies, which led to the current dilemma

What Would I Do?

1. Assess capacity - Request a formal capacity assessment during one of Mrs. Mythili's lucid intervals before making any decision
2. If she has capacity - Respect her refusal, discuss extubation as a compassionate option, initiate palliative care
3. If she lacks capacity - Apply the substituted judgment standard using her clearly and repeatedly expressed prior wishes; counsel the son to help him understand this
4. Engage the son empathetically - Acknowledge his love for his mother, but redirect him to think about what she would have wanted
5. Document everything - The clinical assessment, discussions, and rationale
6. Involve an ethics committee if there is persistent family conflict

The guiding principle here is that a patient's right to refuse treatment - especially one who expressed this clearly, consistently, and across multiple visits - must be respected. Treating her against her known wishes would be a violation of her autonomy and dignity, even if done with the intention of beneficence.
