Informed Consent in Singapore

What is this right?
Every patient in Singapore has the right to informed consent before any medical procedure or treatment:
- Montgomery standard: Following the landmark Hii Chii Kok decision, Singapore law requires doctors to disclose information that a reasonable patient would consider significant when deciding whether to undergo treatment.
- What must be disclosed: The nature of the procedure, material risks, alternatives, and the consequences of not proceeding.
- Voluntariness: Consent must be given freely — without coercion, undue influence, or deception.
- Capacity: The patient must have the mental capacity to understand the information and make a decision.
- Documentation: Consent is typically documented with a signed consent form, but verbal consent is also valid.
When does it apply?
- You are about to undergo any medical procedure, surgery, or treatment — from a routine blood test to major surgery.
- This right applies in all healthcare settings — public hospitals, private clinics, dental offices, and specialist centres.
What to Do If a Doctor in Singapore Performed a Procedure Without Fully Explaining the Risks to You
- Ask questions — if you don't understand something, ask your doctor to explain in simpler terms.
- Ask about risks, alternatives, and what happens if you decline.
- Take time to decide — you are not obliged to consent immediately (except in emergencies).
- If you feel pressured into a procedure, say "I need more time to think" and seek a second opinion.
What should you NOT do?
- Don't sign a consent form you haven't read — ask for clarification on any terms you don't understand.
- Don't assume the doctor knows best without discussion — you have the right to participate in decisions about your own healthcare.
- Don't ignore your right to refuse — competent adults can refuse treatment, even if the doctor considers it necessary.
