In all subjects, PRN lorazepam doses will be administered by mouth (PO) or intravenously (IV) (if subjects cannot take medication PO) whenever CIWA ratings are > 14 per the protocol in the standard alcohol detoxification order set in the UNC Hospital CPOE system. Lorazepam doses (1 - 4 mg) and frequency (q 2 -6 h) will be adjusted based on the severity of withdrawal symptoms. This same order set will be employed at the Dorothea Dix CRU.
