Informed consent may be either “express” or “implied.” Express consent is given in writing or verbally. If a patient’s consent is written, it should include the name of the health care professional who discussed the proposed treatment with the patient, the name of the health care provider who is to perform the procedure, and the date, time and location where the consent form was signed.
Consent not given by a patient in writing or verbally, but understood from the circumstances surrounding the procedure or treatment at issue, is known as implied consent. Consent may be implied when, for instance, a patient presents him or herself for a relatively simple, non-invasive procedure. Consent is also usually implied for necessary procedures a surgeon might perform in the course of a surgical procedure to which the patient did consent.
Situations in Which Informed Consent May not be Necessary or May be Implied
- Situations Not Involving Medical Procedures or Treatment. Not all situations require that informed consent be given. For example, although listening to a heartbeat through a stethoscope may be considered a “treatment” or “procedure,” to some people (especially those who are uncomfortable in physician’s offices), it’s rare that a physician and patient would have a lengthy discussion about the benefits and risks of listening to a heartbeat using that device.
- Emergency Situations: In emergency situations, there is not always time to obtain a patient’s informed consent, or the patient may be unconscious and unable to communicate. If an emergency involves risk to the patient’s life or the patient is unable to communicate, consent may be implied under the rationale that the patient would have consented to emergency treatment.
Obtaining Consent from Incompetent Individuals and Minors
When a competent adult seeks medical treatment, the process of obtaining informed consent may seem relatively easy. However, in situations where mentally disabled individuals or children need treatment, the ability to obtain informed consent becomes more difficult. In these situations, serious questions arise concerning who is able to give informed consent for those individuals.
In most cases, a mentally disabled person has an appointed guardian authorized to make medical decisions and give informed consent for that individual. Medical providers need to make sure that when they obtain informed consent for incompetent individuals, they have obtained it from the correct person or persons.
In most situations, parents can give informed consent for treatment for their minor children. However, some states allow young adults under eighteen to play a more active role in their medical care and treatment, including the process of informed consent. Not every teenager is capable, however, of making informed consent decisions under these laws. Instead, most states focus on “mature minors” sufficiently ready to understand the nature and consequences of treatment. In those states, such young adults may be able to provide consent without consulting with their parents. For example, some states have passed specific laws that allow for minors to consent, without parental knowledge or approval, to health care treatments related to substance abuse, mental health, and sexual activity.
