    IntroductionAlcohol withdrawal treatment varies widely. Benzodiazepines are the standard of care, with rapid onset and long durations of action. Recent drug shortages involving IV benzodiazepines have required incorporation of alternative agents into treatment protocols. Phenobarbital has similar pharmacokinetics to select benzodiazepines frequently used for alcohol withdrawal. The objective of this study is to describe the effectiveness and safety of our institutional protocols during three time periods utilizing benzodiazepines and barbiturates for the acute treatment of alcohol withdrawal in the emergency department.MethodsAdult patients presenting to the ED for acute alcohol withdrawal from April 1st, 2016 to January 31st, 2018 were reviewed. Patients who received at least one dose of treatment were included. Treatments were based on availability of medication and given protocol at time of presentation. The primary outcome was the rate of ICU admission.Results300 patient encounters were included. Overall baseline characteristics were equal across groups, except for age. There was no difference in rate of ICU admission from the ED between groups (D:8, L&P:11, P:13 patients, p = 0.99). Rate of mechanical ventilation was no different across all groups (D:1, L&P:3, P:3 patients, p = 0.55).ConclusionDuring benzodiazepine shortages, phenobarbital is a safe and effective treatment alternative for alcohol withdrawal. Incorporating phenobarbital into a benzodiazepine based protocol or as sole agent led to similar rates of ICU admission, length of stay, and need for mechanical ventilation in patients treated for alcohol withdrawal in the emergency department.Copyright © 2019 Elsevier Inc.
