Informed Consent in Pennsylvania

How Pennsylvania differs from federal law
Pennsylvania has a statutory informed consent framework under the MCARE Act:
- MCARE Act (40 P.S. § 1303.504): Requires physicians to obtain informed consent by disclosing the nature of the procedure, material risks, alternatives, and the likely outcome with or without treatment. Battery claims apply if no consent was obtained; negligence claims apply if consent was inadequate.
- Standard: Pennsylvania uses a "physician-based" standard — what a reasonable physician would disclose under similar circumstances, not what a reasonable patient would want to know.
- Advance Directive for Health Care Act (20 Pa.C.S. § 5421): Allows Pennsylvanians to create living wills and designate healthcare agents for when they cannot make decisions.
- Mental health: The Mental Health Procedures Act (50 P.S. § 7100) provides specific consent protections for psychiatric treatment, including the right to refuse medication in non-emergency situations.
Additional Steps in Pennsylvania
If informed consent was not obtained, consult a medical malpractice attorney. File complaints with the PA Department of State Bureau of Professional and Occupational Affairs at (800) 822-2113. Contact Community Legal Services for medical decision-making advocacy.

Federal baseline: Informed Consent nationwide
What is this right?
The modern doctrine of informed consent traces back to a 1914 New York case, Schloendorff v. Society of New York Hospital, where Justice Cardozo wrote that "every human being of adult years and sound mind has a right to determine what shall be done with his own body." Six decades later, Canterbury v. Spence (D.C. Cir. 1972) added the modern patient-centered standard — what a reasonable patient would want to know, not just what other doctors typically disclose.
What that means in practice: your doctor has to explain the treatment, the reason for recommending it, the risks, the benefits, and the alternatives — including doing nothing. The signed form is just paper. Real informed consent is the conversation. You have to be given enough information to make a meaningful decision, agree voluntarily, and you have the right to refuse any treatment, even one your doctor strongly recommends. A competent adult can refuse a lifesaving transfusion. The law sides with autonomy.
When does it apply?
Informed consent applies when:
- A doctor recommends surgery, a procedure, or a treatment plan.
- You are asked to join a clinical trial or research study.
- A provider wants to prescribe medication with significant risks or side effects.
- You are deciding whether to continue or stop treatment.
The exceptions:
- Medical emergencies. If you are unconscious or unable to communicate and delaying treatment risks death or serious harm, providers can act under the emergency exception.
- Therapeutic privilege. Rare and contested — a doctor may withhold specific information if disclosure would itself seriously harm the patient. Modern courts read this narrowly.
- Patient waiver. You can tell the doctor you don't want the details and want them to decide. The waiver itself has to be genuine and informed.
Three myths:
- "Signing the form is consent." The form is evidence of consent. Real informed consent is the conversation behind it. A signature on an unread form, with no real explanation, doesn't cut it in court.
- "I can't say no to my doctor." You always can. A competent adult can refuse any medical procedure, even lifesaving ones — that's the autonomy principle Cardozo wrote about a century ago.
- "Consent only matters for surgery." It applies to any treatment, test, or procedure with meaningful risk — medications, imaging tests, vaccines, anesthesia, biopsies.
What to Do If a Doctor Treated You Without Your Informed Consent
Step 1: Ask the questions. Before any procedure: What exactly will be done? Why do you recommend it? What are the risks and possible complications? What are the benefits? What are the alternatives? What happens if I do nothing? Write the answers down.
Step 2: Take your time. Outside a true emergency, you are not required to decide on the spot. Ask for written information and take it home. Get a second opinion if the stakes are high.
Step 3: Demand a qualified interpreter if you need one. Healthcare providers receiving federal funding (essentially every Medicare/Medicaid provider) must provide language access services under Title VI of the Civil Rights Act and ACA § 1557. A family member is not the right interpreter for medical decisions.
Step 4: If you refuse, document it. Tell your doctor clearly and ask them to record the refusal in the chart along with their explanation of the risks. The note protects everyone, including you.
Step 5: If you were treated without proper consent, get a lawyer. Lack of informed consent is its own malpractice claim, separate from negligence in the procedure itself. State medical boards and hospital patient advocates also field these complaints.
What should you NOT do?
Don't sign forms you haven't read. Procedure, risks, benefits, alternatives — those should be in the form, and your conversation with the doctor should match. If anything is unclear, slow down and ask.
Don't let anyone rush you. Outside a real emergency, you have the right to think it over, get a second opinion, and talk it through with family.
Don't assume consent rolls over. Consent is specific to a procedure. If your surgeon finds something else during the operation, they generally can't expand the procedure without your prior consent unless an immediate emergency requires it.
Don't confuse consent with a guarantee. Consenting means you accept the documented risks — it does not mean the doctor promised a specific outcome.
