Risk management in clinical practice. Part 2. Getting to 'yes'--the matter of consent.

Consent is an integral part of delivering the care patients want. In order to consent to treatment, patients must have the legal capacity to give valid consent. If this three stage test is satisfied, the patient can elect to have any treatment they wish even if it is not in their best interest. Before a patient is able to consent to treatment they must have adequate knowledge about the risks, benefits and alternatives to the treatment. The amount of information provided to the patient by the dentist is determined to some degree by the legal system prevailing. The patient must voluntarily agree to treatment without being coerced by the dentist or other parties and if things change during treatment the patient needs to be advised. Written consent is very useful in the defence of cases but simply signing the consent form does not mean that the patient knows or understands the treatment to which they have agreed.
