Elements of informed consent

Elements of Informed Consent - The Patient's Permission Slip

• Disclosure: The physician must provide all necessary information.
  • Patient's diagnosis
  • Proposed treatment or procedure
  • Risks and benefits of the treatment
  • Alternative treatments (including no treatment)
  • Risks and benefits of alternatives
• Understanding: The patient must comprehend the disclosed information. Ensure information is in plain language.
• Capacity: The patient must be clinically determined to have the ability to make a rational decision.
• Voluntariness: The decision must be made freely, without coercion or manipulation from others.

⭐ Capacity vs. Competence: Capacity is a clinical determination that can fluctuate. Competence is a legal state determined by a judge; a person is presumed competent unless legally declared otherwise.

Competence vs. Capacity - Who Can Say 'Yes'?

• Competence: A legal status determined by a judge in court. It's a global assessment; adults ≥18 are presumed competent unless legally adjudicated otherwise.
• Capacity: A clinical determination assessed by a physician at the bedside. It is task-specific (e.g., consent for surgery) and can fluctuate, even over the course of a day.

• Key Elements of Decisional Capacity:
  • Communicates a consistent choice.
  • Understands the relevant medical information.
  • Appreciates the situation and its likely consequences.
  • Reasons through the treatment options and provides a rationale.

⭐ A patient who has been involuntarily committed for psychiatric treatment does not automatically lose the right to make their own medical decisions. Capacity must still be assessed for each specific medical decision.

Exceptions to Consent - When Docs Can Decide

• Emergencies

  • Patient lacks decision-making capacity.
  • Immediate threat to life or limb exists.
  • No surrogate is available to provide consent.
  • Procedure is required to save life or prevent serious impairment.
  • Basis: Implied consent is assumed for necessary treatment.

• Patient Incapacity

  • If a patient is deemed to lack capacity (not competent), they cannot legally consent.
  • Consent must be obtained from a designated surrogate or proxy (e.g., healthcare power of attorney, next-of-kin).

• Therapeutic Privilege

  • Rarely used and controversial.
  • Provider may withhold information if disclosure would cause severe, direct, and medically predictable harm (e.g., severe psychological distress leading to treatment refusal).
  • Does not apply if the patient simply might become upset.

• Waiver

  • Patient explicitly and voluntarily waives their right to be informed and consents to the provider deciding for them.
  • Must be documented clearly.

⭐ In a true emergency, consent is implied. However, this only applies until the patient regains capacity or a surrogate becomes available. Once they do, informed consent is required for any subsequent or ongoing treatment.
