What Is Informed Consent in End-of-Life Care?

The short answer: Informed consent is the legal and ethical requirement that patients understand and agree to medical treatments before they are performed. In end-of-life care, informed consent is particularly important because decisions are often irreversible, the stakes are the highest possible, and patients may be cognitively impaired or unable to speak for themselves. Understanding your rights around consent protects you from unwanted treatment.

For consent to be truly informed, the patient must:

Receive information — diagnosis, prognosis, proposed treatment, risks and benefits, alternatives (including no treatment)
Understand the information — in a language and manner they can comprehend; with time to ask questions
Have capacity — the ability to understand, reason, and communicate a decision
Make a voluntary decision — without coercion or pressure
Give consent — which may be verbal, written, or (in emergencies) implied

Capacity vs. Competence

Capacity is a clinical assessment (made by a physician) of whether a patient can make a specific medical decision at a specific moment. Competence is a legal concept (determined by a court). A patient can have capacity for some decisions but not others; capacity can fluctuate. A patient in moderate dementia may still have capacity to consent to or refuse a blood transfusion, even if they lack capacity for complex financial decisions.

When a Patient Lacks Capacity

When a patient lacks decision-making capacity, consent passes to their legally designated surrogate:

The healthcare proxy (named in their advance directive) — highest authority
The legal guardian (if appointed by court)
The next of kin (in legally determined priority order: spouse → adult children → parents → siblings)

Surrogates are supposed to make decisions based on the patient's known wishes and values, not their own preferences.

The Right to Refuse Treatment

Competent adults have the absolute right to refuse any medical treatment — even life-sustaining treatment. This right is protected by common law (Cruzan v. Director, 1990 Supreme Court decision), the Patient Self-Determination Act, and every state's law. A competent patient saying "I do not consent to this" must be honored by the medical team.

Protecting Your Rights

Complete an advance directive naming a healthcare proxy who knows your values. Make sure your medical record contains your advance directive. Talk to your healthcare team about your wishes. If your consent is not being respected, ask for a patient advocate or ethics consultation.

Frequently Asked Questions

In an emergency where you are unable to consent and delay would cause serious harm, physicians can proceed under implied consent. In non-emergency situations, treatment without consent is battery. If you believe your consent was not obtained, speak to the patient advocate or hospital administration.

Does my family have the right to make my medical decisions?

Only if you have designated them as your healthcare proxy, or — if you have no proxy — they are your next of kin in the legal priority order. Your family does not automatically have the right to override your expressed wishes.

What if a patient says no but family says yes?

A competent patient's refusal overrides family wishes. Period. If there is a question about capacity, the clinical team makes the capacity assessment. Family pressure does not override a competent patient's refusal.

Does an advance directive guarantee my wishes will be followed?

It is the strongest legal protection available, but not a guarantee. Healthcare providers are not required to provide treatment they consider medically futile, even if requested. Having a healthcare proxy who can actively advocate for your wishes significantly strengthens your protection.

A death doula can help ensure you understand information being presented, advocate for your right to ask questions and take time to decide, and help communicate your wishes to the medical team. They can also help you identify when to request a patient advocate or ethics consultation.
