A cohort study describing implementation of the ICU Liberation (ABCDEF) bundle reported associations between higher bundle compliance and less delirium and shorter ventilator and ICU time. The bundle covers Assess/manage pain, Both spontaneous awakening and breathing trials, Choice of analgesia and sedation, Delirium monitoring, Early mobility, and Family engagement.
Because it is observational, the study shows association rather than proof, but it aligns with broader evidence that lighter, targeted sedation, daily delirium screening (for example with the CAM-ICU), and early mobilization help patients spend less time confused and ventilated. Nurses perform most of these elements: the awakening trials, the CAM-ICU screen, and getting patients moving.
Why this matters on shift
ICU delirium is common and linked to worse outcomes, and much of the bundle is nurse-delivered. Screening every shift, coordinating sedation interruptions, and mobilizing patients early are where ICU nurses directly influence delirium and time on the ventilator.
