Informed Consent

Informed Consent - Sealing the Deal Safely

• Definition: Patient's voluntary agreement to a procedure after understanding adequate information. Upholds patient autonomy; legal prerequisite.
• Core Components:
  • Nature & purpose of procedure.
  • Significant risks & expected benefits.
  • Alternatives, including no treatment.
  • Patient's capacity to understand & decide.
  • Voluntary decision, without coercion.
• Documentation: Written, signed, witnessed. Legally vital.
• Indian Law: IPC Sec 88 (consent), Sec 92 (implied in emergency).

  ⭐ For emergency life-saving procedures on an unconscious adult with no available relatives, consent is implied under IPC Section 92.

• Exceptions: True emergencies, therapeutic privilege (limited), waiver.

Elements of Consent - The Four Pillars

📌 Mnemonic: C-DUV

• Competence (Capacity):
  • Patient's ability to understand & make a reasoned decision.
  • Assessed by: understanding, retaining, weighing, communicating.
  • Incompetence requires surrogate consent (e.g., next of kin).
• Disclosure (Information):
  • Sufficient information: diagnosis, procedure (nature, purpose), risks (common, serious), benefits, alternatives (incl. no treatment), prognosis.
  • "Reasonable patient" standard often applied.
• Understanding (Comprehension):
  • Patient genuinely comprehends disclosed material.
  • Clinician ensures clarity, avoids jargon, confirms understanding (e.g., teach-back).
• Voluntariness (Free Will):
  • Decision made freely, without coercion, manipulation, or undue influence.
  • Right to refuse/withdraw consent anytime.

⭐ For an incompetent adult patient in India, consent hierarchy is typically: spouse, then major children, parents, or siblings in that order of preference if the preceding relative is unavailable or unwilling to consent.

Consent Process - Protocol & Paperwork

• Types of Consent:
  • Expressed: Oral or written (preferred for procedures).
  • Implied: Inferred by conduct; vital in emergencies (life-saving).
• Documentation Essentials:
  • Written, signed, dated, timed.
  • Patient (competent adult ≥18 yrs) or Legally Authorized Representative (LAR).
  • Doctor obtaining consent.
  • Witness (impartial, e.g., nurse).
  • Understandable language (translator if needed).
• Consent Protocol:

📌 BRAN: **B**enefits, **R**isks, **A**lternatives, **N**ature of procedure & No treatment.

⭐ IPC Section 92 allows doctors to act in good faith for the patient's benefit in emergencies where consent cannot be obtained, if not intended to cause death.

Special Situations - Navigating Grey Areas

• Emergencies:
  • Implied consent: immediate threat to life/limb.
  • Document necessity & inability to obtain consent.
• Minors (< 18 years):
  • Parental/legal guardian consent.
  • Emergency: treat to save life/limb.
  • 📌 Gillick competence (UK concept) for mature minors has limited Indian relevance.
• Incapacitated Adults (Unconscious/Incompetent):
  • Surrogate consent (next-of-kin hierarchy).
  • Advance directives (if available).
  • Act in patient's best interest if no surrogate.
• Refusal of Treatment:
  • Competent adult's right.
  • Inform of risks; document thoroughly.
• Jehovah's Witnesses:
  • Respect competent adult's refusal of blood.
  • Explore alternatives.
  • Children: Court intervention may be sought for life-saving transfusions.

⭐ In an emergency, if a patient cannot consent and no surrogate is available, life-saving treatment is permissible under implied consent or necessity.
