Informed Consent in Hospitals: What You Need to Know
Informed consent is a fundamental patient right that ensures you understand and agree to medical treatments before they happen. Knowing what informed consent means helps you make empowered decisions about your care.
What Is Informed Consent?
Informed consent is the process by which a healthcare provider explains a proposed treatment or procedure so you can make a knowledgeable decision about whether to proceed. It requires:
- Information: The provider gives you adequate information about the treatment
- Understanding: The information is presented in a way you can comprehend
- Voluntariness: Your decision is made freely, without coercion or undue pressure
- Competence: You have the mental capacity to make the decision
What Your Doctor Must Tell You
Before any significant procedure or treatment, your provider should explain:
- Your diagnosis or medical condition
- The proposed treatment or procedure and its purpose
- The expected benefits of the treatment
- The risks and potential complications
- Alternative treatments and their risks and benefits
- What might happen if you choose no treatment
- The likelihood of success
When Informed Consent Is Required
- Surgical procedures
- Invasive diagnostic tests
- Blood transfusions
- Anesthesia
- Radiation therapy and chemotherapy
- Certain medications with significant risks
- Participation in clinical trials or research
Exceptions to Informed Consent
- Medical emergencies: When you're unconscious or unable to consent and delay would endanger your life
- Implied consent: Routine, low-risk procedures (blood pressure measurement, basic blood draws)
- Therapeutic privilege: Rarely, when the provider believes full disclosure would seriously harm the patient (this is controversial and limited)
- Patient waiver: When you voluntarily waive your right to detailed information
Your Rights in the Consent Process
- Take time to consider your options — you don't have to decide immediately
- Ask as many questions as you need
- Request information in your preferred language
- Withdraw consent at any time, even after signing a form
- Refuse any treatment
- Have a family member or advocate present during the discussion
- Request a second opinion before consenting
Tips for the Informed Consent Process
- Read consent forms carefully before signing — don't just sign where indicated
- Ask questions about anything you don't understand
- Write down your questions beforehand
- Bring a trusted person who can help you process the information
- Don't feel pressured to sign immediately
- Ask for written materials to review

Important
This article explains how hospital quality data works and is for general information only. It is not medical advice and must not be used to decide whether to seek, delay or refuse care — that is a decision for you and a clinician who knows your situation.
CMS quality measures describe care delivered during earlier reporting periods and are refreshed roughly quarterly. A hospital's staffing, services and performance can change well before the published numbers do.
