Procedures: Most patients who are admitted to the UNC Neuroscience Hospital Crisis Stabilization Unit, UNC Hospitals Family Practice or Hospitalist Services, or the Dix CRU for medical detoxification from alcohol will come in through the UNC Hospitals Emergency Department or Dorothea Dix Screening and Admissions during the late evening or early morning. Physical examination, medical and psychiatric history and lab tests (including complete blood count [CBC], magnesium, sodium, potassium, [blood urea nitrogen] BUN, creatinine, glucose, albumin, liver functions tests [ALT, AST, LDH, GGT], throid-stimulating hormone (TSH), B12, folate, urinalysis, urine toxicology screen and pregnancy test) are routinely obtained by the emergency department (ED)/ Dorothea Dix Screening and Admissions and/or inpatient unit during the admission process. Possibly in the UNC Hospitals ED/ Dorothea Dix Screening and Admissions and definitely after admission to these units, patients will have their vital signs (VSs) measured and their withdrawal symptoms quantified using the revised Clinical Institute Withdrawal Assessment for Alcohol scale (CIWA-Ar scale, Sullivan et al 1989) on the schedule in the standard alcohol detoxification order set in the UNC Hospital electronic medical records system (CPOE) system. The CRU at Dorothea Dix will use a hard copy version of the CIWA used in the CPOE at UNC Hospitals.
