Consent to HealthcareAn adult (aged 18 or older) can give their consent to accept or refuse medical treatment if they have capacity.
‘Capacity’ is a person’s ability to:
- understand the nature and effect of decisions
- freely and voluntarily make decisions
- communicate those decisions in some way.
ConsentBefore a person can consent to or refuse particular medical treatment, they need to have a reasonable understanding of what that treatment involves. The treating health practitioner is required to provide a proper explanation of the medical treatment and the risks involved.
A health professional has a duty to warn a patient of a material risk inherent in proposed treatment (see the High Court of Australia decision in Rogers v Whittaker (1992) 175 CLR 479;  HCA 58). A risk is evident if in the particular case:
- a reasonable person in the patient’s position, if warned of the risk, would be likely to attach significance to it
- the health practitioner is, or should reasonably be, aware that the particular patient, if warned of the risk, would be likely to attach significance to the risk.
- the condition of the patient and their general health
- the nature of the medical treatment
- what will happen if the treatment fails or goes wrong
- how likely it is that a failure or particular risk may occur
- the seriousness of the effect on the patient’s health or life if a particular risk occurs
- whether the patient appears to want a full explanation of what is involved, the nature and the availability of alternative treatment
- the personality or temperament of the patient
- whether the treatment is needed because of an emergency (e.g. a car accident).
- reasonable grounds for believing that the physical or mental health of the patient might be seriously harmed by knowing particular information
- a patient does not wish to know all the information associated with their medical treatment. However, this does not mean the medical practitioner is not required to provide any information. In order for consent to be informed and valid, the patient must still be provided with enough information to enable them to properly consent
- the patient is unable to provide consent (e.g. the patient is unconscious). Treatment in this situation can only be provided if it is reasonably necessary in the best interests of the patient. When a person is unable to provide consent, consent can be provided by a person’s statutory health attorney.
Types of consentWhere consent is provided to medical treatment by a person it must be freely given. The consent provided can either be:
- express—for example a person signs a form consenting to a particular surgical procedure or
- implied—for example, by the actions of the individual attending at a pathology centre, handing over the collection request form and presenting an arm for the blood test.
Privacy and Rights to informationAny personal information collected about a patient during contact with the health practitioner must be treated in accordance with the relevant privacy laws and must not be used or disclosed in a way that is inconsistent with those laws.
If the patient experiences complications during or after the surgery, they may wish to access their medical records if the explanation provided by the health practitioner or the hospital of admission is not satisfactory.
The patient may wish to complain about the treatment they received or the conduct of the health practitioner or bring other legal action against the practitioner.
