Consent to treatment is the principle that a person must give permission before they receive any type of medical treatment, test, or examination. This is requested on the basis that a clinician has provided a thorough explanation of the required procedure. Consent is required regardless of the nature of the intervention, whether it is a simple physical examination or a complex surgical procedure. This principle is a cornerstone of medical ethics and international human rights law.
For consent to be valid, it must be voluntary and informed, and the person consenting must have the capacity to make the decision. Voluntary means the decision must be made by the person themselves without pressure from medical staff, friends, or family. Informed means the person has been given all relevant information, including the benefits and risks, reasonable alternative treatments, and the implications of not proceeding with treatment. Capacity means the person is capable of understanding the information provided and using it to reach a decision.
If an adult has the legal capacity to make a voluntary and informed decision, their choice must be respected. This remains true even if refusing treatment would result in serious harm or death. If a person lacks the capacity to make a decision, healthcare professionals may provide treatment if they believe it is in the person’s best interests. In such cases, clinicians should take reasonable steps to consult with the patient’s family or friends before proceeding.
Consent can be expressed in several ways. It may be given verbally, such as agreeing to an X-ray, or in writing, which is standard for major surgeries. Non-verbal consent is also recognised, such as a patient holding out their arm for a blood test. Consent should be given directly to the healthcare professional responsible for the treatment, such as a nurse, GP, or surgeon. For major procedures, consent should ideally be discussed well in advance to allow the patient time to ask questions. A patient is entitled to withdraw their consent at any point before the procedure begins.
There are specific circumstances where treatment may be administered without consent. Emergency treatment may be provided to save a life if the person is incapacitated or unconscious. Additionally, if an emergency arises during a surgery that requires an immediate additional procedure, doctors may proceed if it is unsafe to wait.
Certain legal frameworks allow for treatment without consent in defined situations. This includes individuals detained under mental health legislation who require treatment for a mental health condition, or individuals who pose a significant risk to public health due to certain infectious diseases. In cases involving life-sustaining treatments where a patient cannot communicate their wishes, decisions are made based on the person’s best interests after consultation with loved ones and, in complex cases, the courts.
When treating patients under the age of 18, consent is typically obtained from someone with parental responsibility. However, young people aged 16 or 17 are generally presumed to have the capacity to consent. Children under 16 may also provide their own consent if they are deemed to have sufficient maturity and understanding of the treatment and its consequences.
If you feel you have received treatment without providing valid consent, you have the right to raise the matter. You may do so by contacting the practice manager or the relevant healthcare provider to initiate a formal review of the process.
