⚖️ Bottom Line:

This new restatement from the ALI encourages courts to consider evidence-based practice alongside (and potentially instead of) traditional custom, marking a significant evolution in how medical negligence may be legally defined. However, custom remains influential in many jurisdictions—clinicians should stay informed as standards shift.

🔍 Key Points:

  • Context: The American Law Institute (ALI) revised the legal standard for medical malpractice in 2024, prompting a shift in how courts may assess medical negligence.

  • Old Standard: Historically, malpractice judgments relied on customary practice—what other physicians typically do.

  • New Standard:

    • Emphasizes reasonable medical care over custom.

    • Defines this care as reflecting the skill and knowledge expected of competent clinicians in similar circumstances.

    • Allows juries to reject outdated customs if they conflict with modern standards.

    • Encourages the use of evidence-based guidelines, while noting that not all guidelines are of equal quality.

    • Expands attention to informed consent and physician-patient communication.

  • Implications:

    • Patient safety and evidence-based care become more central in legal assessments.

    • Physicians may face greater scrutiny of their clinical reasoning, even if their actions align with common practice.

    • There will likely be state-to-state variability in adoption.
