Alcohol Use Disorder among General Hospital Medical Inpatients

Objectives: We sought to examine alcohol use disorder (AUD) among general hospital medical inpatients with respect to identification, service utilization, and initiation of medication-assisted treatment. Methods: We performed a retrospective chart review for all adult inpatients over one full calendar year. Subjects were separated into two categories: patients with chart documentation of an AUD diagnosis and those without such documentation. We extracted from the electronic health record and analyzed information on demographics, service utilization, and treatment initiation of medication-assisted treatment for AUD such as naltrexone, disulfiram, or acamprosate. Results: The study revealed three main findings: 1) Less than one percent of patients discharged from the hospital in one full calendar year had an identified AUD diagnosis. 2) Patients with an AUD diagnosis had a significantly higher number of emergency department (ED) visits and longer hospital length of stay (LOS) but did not have significantly higher 30-day hospital readmissions, compared to patients with no AUD diagnosis. 3) Among patients diagnosed with AUD, only 1.8% received FDA-approved medication-assisted treatment for AUD. Conclusions: The AUD identification rate we detected was markedly lower than prevalence rates reported in the literature. Patients who were identified with AUD had higher counts of ED visits and longer LOS. Initiation rates of medication-assisted treatment for AUD were low. The study findings suggest that concerted efforts are needed to improve detection and diagnosis of AUD in order to support the delivery of effective AUD treatment including the initiation of evidence-based pharmacotherapy for AUD in the general hospital setting.
