What is informed consent?

To give informed consent, you need to be given enough information to make decisions about your health and proposed treatments.

Your doctor must:

  • explain your medical condition
  • recommended treatment
  • other treatment options
  • benefits and risks
  • possible complications.

If you agree to the treatment, your doctor may ask you to sign a consent form. This gives them legal permission to treat you.

Informed consent in health care.

Before you decide to have health tests or treatment, it's important you understand the meaning of informed consent in healthcare. I will explain what informed consent means for you, and what you need to know before making decisions about your health. What is informed consent in healthcare? When you visit a health service, your doctors, nurses and other health workers will tell People do their best to help you with your health problems.

Sometimes you'll need to have tests or treatment. If your health worker wants to test or treat you, they must ask you for your consent first. Informed consent is when you clearly understand your illness or health problem and agree to what your health worker is going to do. Remember, you have the choice to have treatment or not.

What information do I need? To help you make a decision about tests and treatments, about having, your health worker will give you some important information. You can also ask questions such as, what is my illness or health problem? What is the test or treatment? How will the test or treatment help me? Can the test or treatment cause any problems?

How serious can the problems be? Are there different tests or treatments? What happens after the test or treatment? Will I get better? How long will it be? What may happen if I don't get treatment? Please tell your health worker if you don't understand anything they've talked to you about. Why do I have to give consent?

It is the law in Australia that your health worker has your consent before giving you a health test or treating you. Why do I need to sign a consent form? You'll be asked to sign a written consent form for high risk treatments like surgery. Other times you might only need to tell your health worker that you agree to what they're going to do.

Your consent form is only going to be read by those involved in your health care and won't be shared with anyone else. Who can give consent? You'll need to give your own consent if you understand your treatment options and can tell your health worker what you want to do. You can bring your family, friends or community members for support.

And ask them for advice. When you are in an emergency, sometimes your health worker, a family member or friend, can make decisions for you. Who gives consent for a child? Usually a parent, guardian or carer gives consent for a child that is under 18 years of age. Only in cases when a child can fully understand their treatment and the effect it can have on their health can they give their own consent.

Your health worker will check if a child can give their consent. How much do I need to know? Health workers will give you as much information as you want and will try to answer all of your questions. You can tell your health worker if there's anything you don't want to know about your tests or treatment.

How much time do I have to decide? Decisions have to be made quickly in emergencies. If it's not an emergency, you can't decide. If you're still unsure, you can talk to another health worker to help you make your decision. Do I need an interpreter? Sometimes it can be hard understanding what you need to know about your test or treatment.

It's important that if you're going to make the best decision about your health, that you and your health worker understand each other. If English isn't your first language, a professional interpreter can attend your appointment. Both face to face interpreters and telephone interpreters are free. You or your health worker can ask to have an interpreter attend your appointments.

Remember that everything you tell your interpreter is private. What if I gave consent and then I changed my mind? You can always change your mind, even if you've signed a consent form or told your health worker that you agree to have tests or treatment. Remember, ask questions. It's important that you understand everything you say.

Everything your health worker has talked to you about. You can ask as many questions as you want, and you can bring someone with you for support. Ask for an interpreter. Professional interpreters are free, and they make it easier for you and your health worker to understand each other. It is your choice.

Even if you gave consent, you can change your mind at any time.

Who can give consent

You must be legally capable to give consent.

This means you understand all the information your doctor has given you about your condition and proposed treatment. You must also be able to communicate your decision to your doctor.

If it’s an emergency, a health professional or a family member may need to consent to emergency treatment on your behalf.

If you're over 18

If you’re over 18 you can give consent unless you have a mental illness or disability that affects your legal capacity. If you’re unconscious another person, such as your doctor or family member, will also have to make decisions and give consent on your behalf.

If you're under 18

If you’re under 18, your parent, guardian or carer will usually need to give consent for you. You may be able to give consent yourself if you understand your condition, and everything about the recommended treatment.

Giving consent

You can give informed consent verbally or in writing.

For example, consenting verbally would include your GP recommending a type of medicine and with your agreement, giving you a prescription.

For more complex procedures or treatments, such as surgery, your doctor will ask you to sign a consent form.

What to ask your doctor or surgeon

You can ask your doctor or surgeon anything about the treatment or procedure they’re recommending. If you don’t understand something, you can ask them to explain it again. You can also have a friend, family member or support person with you.

Questions to ask may include:

  • do I really need it?
  • how long will it take me to recover?
  • what is the success rate for the procedure?
  • what are the risks and possible complications?
  • are there other treatment options?
  • what happens if I do nothing?
  • does it cost anything?

If you're deaf, hard of hearing or would like to use a language other than English, we have free interpreters who can go to your appointments with you.

Changing your mind

You can change your mind at any time, even if you've signed a consent form or agreed to have tests or treatment.
