What is the difference between withholding and withdrawing life-sustaining treatment?

• A. Withholding is stopping an ongoing treatment; withdrawing is never ethically permissible.
• B. Withholding is not initiating a treatment; withdrawing is stopping an ongoing treatment; both may be ethically permissible.
• C. Withholding and withdrawing are identical in every ethical framework.
• D. Withholding requires patient consent while withdrawing does not.

Answer: (B)

The main idea here is that withholding and withdrawing life-sustaining treatment are treated as two sides of the same ethical coin when they align with the patient’s values and medical reality. Withholding means not starting a treatment that could prolong life, while withdrawing means stopping a treatment that is already underway. Both decisions can be ethically permissible when they reflect the patient’s wishes (via an advance directive or a surrogate decision-maker) and when continuing the treatment would not be beneficial, would cause more harm than good, or would not respect the patient’s goals of care. The key is honoring autonomy, aiming for the patient’s comfort and overall well-being, and following an appropriate decision-making process with the patient or their surrogate.

In short, withholding is not initiating a treatment; withdrawing is stopping one that’s already in place, and both may be ethically acceptable under the right ethical and clinical circumstances.
