The North American Spine Society is committed to quality patient care through promotion of patient safety and prevention of medical errors. NASS monitors government and other resources for patient safety-related notices that may be useful to members. Drug and device notices are color coded as yellow (low-impact “Cautionary Notice”), orange (moderate-impact “Warning”), or red (high-impact “Alert”) and will be posted below for up to one year or until the notice expires.
