Valid consent
Discuss material benefits, risks, alternatives and no treatment in a form the patient understands. Check voluntariness and decision-making ability.
Understand
Consent is a continuing conversation about diagnosis, benefits, material risks, alternatives and no treatment, shaped by what this patient considers significant. It requires capacity and voluntariness.
Assess
Explain uncertainty and likely recovery in plain language, invite questions and use an interpreter or accessible format where needed. Check understanding rather than simply obtaining a signature.
Apply
Document the decision and salient discussion. A new finding or change in plan may require renewed consent; respect a capable patient's refusal.
Key distinctions
Material risk is judged from the patient's perspective as well as clinical frequency. Explore what outcome would matter to them: altered sensation, a visible scar, time off work or failure to save a tooth. The decision must be voluntary and informed, and consent can be withdrawn. Document dialogue, not just a form and a list of generic complications.
Think through a case
A patient says that even a small risk of altered lip sensation would change their decision about lower third molar surgery. That makes the risk central to their consent discussion.
The distinction to remember
Do not rely on a signed standard form to prove the patient understood a material, individual risk.
Test your recall
Is a signed form sufficient by itself?
Show answer
No; it records, but does not replace, a valid discussion.
