What Is the Difference Between Express and Implied Consent?

A healthcare professional, such as a doctor, needs your informed consent in order to provide you with medical treatment. From their point of view, your consent protects them against medical malpractice liability. It protects you against medical treatment that you don’t want. Express consent and implied consent are the two main types of consent

What is express consent? Express consent arises when you tell someone in so many words, “I consent to [description of medical treatment],” after learning about the treatment and its risks. This is express permission for your healthcare provider to perform medical treatment on you. 

Most of the time, express consent applies when you sign a document giving your doctor permission to perform medical treatment on you. This document can serve as evidence in a medical malpractice claim. Your doctor can use it as evidence of informed consent, and you can use it as evidence of the establishment of a doctor-patient relationship.

Always read your consent form before you sign it. It should include the following information:

  • Your diagnosis;
  • A detailed description of the proposed treatment;
  • A description of the benefits of the treatment;
  • The risks and possible side effects of the treatment; and
  • A statement of why your doctor believes the treatment is your best option.

Your signature on the consent form constitutes your agreement that you understand the contents of the consent form and still agree to treatment.

The following medical treatments always or usually require patient consent:

  • Surgery;
  • Anesthesia, especially general anesthesia;
  • Biopsies;
  • Blood transfusions;
  • Chemotherapy;
  • Blood testing for a disease (such as HIV); and
  • Vaccinations.

Other medical treatments may require consent as well.

What is implied consent? Implied consent occurs when you indicate through your actions that you consent to a procedure. It also includes circumstances where consent is implied by the circumstances.

Following are some examples of implied consent:

  • Sitting down in the doctor’s office and rolling up your sleeve after the doctor proposes giving you an injection;
  • Going to a lab to get your blood drawn; and
  • Showing up for a routine physical exam.

If you show up for an injection and the doctor decides on the spot that you need emergency surgery, however, your doctor will need your express consent. Other examples of implied consent arise when:

  • You need emergency medical treatment, but you are unconscious or unable to speak or write. Your doctor can assume, for example, that you consent to life-saving surgery after a car accident.
  • You are an infant or a small child.
  • You are mentally ill or mentally disabled.
  • There is a language barrier between you and your doctor.

There may be other situations that allow your healthcare provider to presume your consent to medical treatment.

You might anticipate that your doctor will assert a consent defense to your medical malpractice claim. This defense only works under limited circumstances. You can consent to a risky medical treatment, for example, but no court will presume that you consented to incompetent medical care. 

Although consent is not a valid defense against incompetent medical care, lack of consent can constitute medical battery under California law. Consent is lacking if:

  • Your doctor never sought consent even when it was possible and convenient to do so;
  • Your doctor obtained your “consent” without informing you of the true risks of the procedure;
  • Your doctor obtained your consent to unnecessary medical treatment by exaggerating your need for it; or
  • Your doctor obtained your consent for one procedure but actually performed another procedure.

You can win medical malpractice compensation if you were harmed by the procedure.
