Wrong-site surgery is considered a never event and can lead to serious patient harm. This analysis of closed medical malpractice claims on wrong-site surgery between 2013 and 2020 concluded that the risk of wrong-site surgery increases with spinal surgeries (e.g., spinal fusion, excision of intervertebral discs). The primary contributing factors to wrong-site surgery was failure to follow policy or protocols (such as failure to follow the Universal Protocol) and failure to review medical records.
