The Ultra-Brief 2-Item delirium screen (UB-2) is designed for very rapid delirium triage in busy clinical settings. It uses two simple cognitive prompts; failing either item is typically considered a positive screen and prompts more comprehensive delirium assessment.
Formula: UB-2 result is based on number of failed items (0-2); any failure is positive.
UB-2 has reported utility as a rapid first-pass delirium screen in hospitalized older adults.
A positive UB-2 screen indicates possible delirium and need for further diagnostic assessment.
Use for quick front-line delirium triage when time constraints limit longer screening tools.
As an ultra-brief screen, UB-2 prioritizes speed and should not be used as a standalone diagnostic test.
