To ensure patient safety during surgery, the Queen Elizabeth Hospital follows the World Health Organization’s “Surgical Safety Checklist.” The checklist applies safeguards at three points during the surgical process – prior to anesthesia, prior to incision, and prior to leaving the operating room. This involves a minimum of one nurse, the anesthesiologist, and the surgeon. Safeguards include confirming the patient’s identity, marking the surgical site when appropriate, verifying technologies and medications, identifying allergies, counting surgical tools before closure, and addressing post-surgical treatment needs.
