Introduction of an Electronic Mobile Device Version of an Alcohol Impairment Scale (the Hack's Impairment Index Score) Does Not Impair Nursing Assessment of Patients in Emergency Departments.

Background: There is no formal assessment to determine level of disability in the millions of patients with alcohol-induced impairment who present to emergency departments annually. Hack's Impairment Index (HII) is a standardized, serializable clinical tool designed to quantify ability. Nursing staff members at this center perform the HII and determine a score using paper prompts.
