Detailed description: Studies show that symptom-triggered dosing is best for treatment of alcohol withdrawal in patients on chemical dependence units without other illness. On general medical hospital wards, withdrawal may be affected by comorbid medical illness. A clinical trial was undertaken to determine whether there is a difference between symptom-triggered (ST) and fixed-schedule (FS) dosing of lorazepam in patients hospitalized on general medical wards at a University medical center. Subjects were assessed by their nurses with the Revised Clinical Institute Withdrawal Assessment for Alcohol (CIWA-Ar) scale. Subjects in the ST arm received lorazepam doses based on CIWA-Ar score. Subjects in the FS arm received scheduled lorazepam with tapering over 4 days.
