Knowing when to stop: futility in the ICU

Area of Science:

• Medical Ethics
• Intensive Care Medicine
• Clinical Decision-Making

Background:

• Withdrawing or withholding life-sustaining treatment is common in intensive care units (ICUs).
• Disagreements between families and clinicians regarding the cessation of treatment often arise.
• This review addresses ethical and practical challenges in intensive care futility judgments.

Purpose of the Study:

• To review recent literature on medical futility judgments in intensive care.
• To emphasize ethical considerations and practical implications of these judgments.
• To explore solutions for resolving disputes regarding treatment futility.

Main Methods:

• Literature review of recent studies on futility in intensive care.
• Analysis of ethical and practical questions surrounding futility judgments.
• Examination of evolving language and definitions of medical futility.

Main Results:

• The concept of 'futility' in medicine is evolving, with families often challenging medical assessments.
• Data-driven attempts to define futility have been hindered by inconsistent definitions.
• A due-process model has emerged as a potential framework for resolving futility disputes.

Conclusions:

• Defining criteria for unilateral treatment withdrawal remains challenging.
• Clinicians can ethically refuse to provide medically inappropriate or futile treatment.
• Understanding the basis of futility judgments is key to resolving disputes.
