What is the definition of informed consent?

Informed consent refers to the process in which healthcare providers give patients all relevant information regarding a treatment or procedure before it is undertaken. This includes explaining the nature of the treatment, potential risks and benefits, and any alternatives available. The aim is to ensure that patients are fully aware of what they are agreeing to and can make an educated decision about their care. By providing all necessary information prior to treatment, healthcare professionals respect the autonomy of the patient and ensure that they can give informed consent based on a clear understanding of the situation.

The other options do not fit the definition of informed consent. Notifying a patient post-treatment does not allow for an informed choice before the treatment occurs. Receiving consent from a patient's family may not involve the patient's direct understanding and agreement, and ensuring a patient understands their bill relates to financial transparency rather than the medical decision-making process.
