Wrong-Site Surgery Resource Center
Wrong-site surgery is classified as a medical "never event" — a preventable error that should not happen. This site provides educational information about what it is, how common it is, and what options patients may have.
Wrong-site surgery refers to any surgical procedure performed on the wrong body part, the wrong side of the body, the wrong patient, or the wrong procedure entirely. These are classified as "never events" — meaning they are so serious and preventable that medical regulators say they should never occur.
These errors can result in permanent harm: unnecessary tissue or organ removal, additional corrective surgeries, infections, long-term disability, and significant emotional trauma.
