Surgical Consent Form

A Surgical Consent Form in the United States authorises a defined activity and evidences that the necessary permission was given.

The legal requirement for informed consent before surgery rests on two distinct tort theories. The first is battery — performing surgery on a patient without any consent, or on a body part or organ not covered by the consent given, is an unlawful touching that gives rise to liability regardless of the quality of the surgical outcome. The second is negligence — performing surgery after obtaining only general consent, without specifically disclosing material risks that a reasonable patient would consider significant, may constitute medical negligence if an undisclosed risk materializes and causes harm, and the patient proves they would have declined surgery had the risk been disclosed.

Most US states apply the objective reasonable patient standard for measuring the adequacy of surgical informed consent disclosure, derived from Canterbury v. Spence, 464 F.2d 772 (D.C. Cir. 1972) — the seminal informed consent case in US medical law — which held that a physician must disclose information that a reasonable patient would consider material to the decision whether to undergo the proposed treatment. A minority of states including New York, New Jersey, and Pennsylvania apply the professional standard, which measures disclosure against what a reasonable physician in the same specialty would disclose.

The Joint Commission (TJC), which accredits approximately 22,000 US healthcare organizations and programs, requires accredited hospitals to obtain and document informed consent before surgical procedures as a condition of accreditation under TJC Standard RI.01.03.01. TJC standards require that informed consent be obtained and documented in the medical record, that the consent discussion occur before preoperative sedation, and that the consent form identify the procedure, the responsible practitioner, and the patient or authorized representative who provided consent.

The Centers for Medicare and Medicaid Services (CMS) Conditions of Participation for Hospitals (42 CFR § 482.13(b)) require hospitals that participate in Medicare and Medicaid to protect and promote each patient's right to make informed decisions regarding their care, including the right to refuse treatment, and to have those decisions documented in the patient's medical record. Non-compliance with the CMS Conditions of Participation can result in loss of Medicare and Medicaid certification, a serious financial consequence for any hospital.

A Surgical Consent Form is needed before every surgical procedure performed in a US hospital, ambulatory surgery center (ASC), or outpatient surgical facility, from minor office-based procedures under local anesthesia to major inpatient surgery under general anesthesia.

Elective surgical procedures — including orthopedic surgery (joint replacement, ACL reconstruction, spinal fusion), general surgery (cholecystectomy, hernia repair, appendectomy), cosmetic and reconstructive surgery (rhinoplasty, breast augmentation, mastectomy reconstruction), cardiovascular surgery (coronary artery bypass grafting — CABG, valve repair), and ophthalmologic procedures (cataract extraction, LASIK, retinal repair) — require written informed consent obtained before the patient is premedicated or sedated.

Ambulatory surgery centers (ASCs) — which performed approximately 60% of all surgical procedures in the US as of 2023, according to the Ambulatory Surgery Center Association (ASCA) — must obtain written informed consent that complies with applicable state surgical consent statutes and CMS Conditions of Participation for ASCs under 42 CFR § 416.50(d).

Emergency surgical procedures present the most legally complex consent scenarios. Where a patient is conscious and has capacity, consent must be obtained even in emergencies. Where a patient lacks capacity due to unconsciousness, altered mental status, or acute psychiatric crisis, surgery may proceed under the emergency exception to the consent requirement — which applies when delay to obtain consent would result in death or serious bodily harm — but the clinical basis for invoking the emergency exception must be documented contemporaneously in the medical record.

Surgical procedures on minor patients require consent from a parent or legal guardian, with the exception of emancipated minors, mature minors recognized under applicable state law, and specific categories of treatment (reproductive health, STI treatment, substance abuse, mental health) for which minors may consent independently in most states. For pediatric surgery, the hospital should verify the consenting adult's legal authority — especially in cases of divorce, custody disputes, or foster care — before obtaining consent.

Reoperation and revision surgery requires a separate consent form from the original procedure consent because the risks, benefits, and alternatives may differ from the initial consent discussion, and the patient has the right to reconsider their decision in light of the first procedure's outcome.

A complete US Surgical Consent Form addresses the following essential components required by TJC standards, CMS Conditions of Participation, and state informed consent law.

The procedure identification section names the specific surgical procedure in both its technical medical name (e.g., laparoscopic cholecystectomy) and a plain-language description (removal of the gallbladder using small incisions and a camera), the anatomical site and laterality (left versus right for paired organs and extremities, with explicit notation to prevent wrong-site surgery), and the name of the primary surgeon responsible for the procedure. TJC's Universal Protocol (implemented through the National Patient Safety Goals) requires verification of correct patient, procedure, and site before incision.

The risk disclosure section lists the material risks of the specific procedure, with particular attention to risks that are serious (though perhaps rare) and risks that are relatively frequent. Courts applying the reasonable patient standard have required disclosure of risks including: death and permanent disability; organ damage; infection; anesthesia complications; blood clots and pulmonary embolism; transfusion risks; stroke and cardiac events; scarring and wound healing complications; failure of the procedure; and the need for additional surgery. The disclosure should be procedure-specific — a consent form for laparoscopic appendectomy should disclose different risks than a consent form for total knee arthroplasty.

The alternatives disclosure section describes the treatment alternatives to the proposed surgical procedure, including non-surgical management options, watchful waiting, and the likely outcome of refusing surgery. For elective procedures, the patient's choice to defer or decline surgery must be acknowledged as a valid option.

The anesthesia consent section, whether included in the surgical consent form or on a separate document, must disclose the type of anesthesia planned (general, regional/neuraxial, local with monitored anesthesia care — MAC, or sedation), the provider responsible for anesthesia care (anesthesiologist, certified registered nurse anesthetist — CRNA, or anesthesiologist assistant — AA), the specific risks of the anesthesia type, NPO requirements, and the patient's right to request or refuse a specific anesthesia type.

The blood and blood products authorization section addresses the patient's consent to receive blood transfusions or blood-derived products if clinically necessary during surgery. For patients with religious objections to blood transfusion — particularly members of the Jehovah's Witnesses — a specific blood refusal form should be executed, and the legal and medical implications of blood refusal should be documented.

The photography and educational use clause, where applicable, obtains the patient's consent to photographs, video recording, or observation of the surgical procedure for educational purposes, noting that such consent is separate from the clinical consent and may be declined without affecting the quality of care.

The patient acknowledgment and revocation rights clause confirms that the patient has been given the opportunity to ask questions, has received satisfactory answers, is signing voluntarily without coercion, and understands that consent may be withdrawn at any time before the procedure begins. The clause should reference the patient's right to revoke consent consistent with the CMS Conditions of Participation at 42 CFR § 482.13(b)(2).
