Effect of ABCDE Bundle Implementation on Prevalence of Delirium in Intensive Care Unit Patients.

Background: The ABCDE bundle incorporates multidisciplinary measures to improve and/or preserve patients' physical, functional, and neurocognitive status through awakening and breathing coordination, delirium prevention and management, and early physical mobility.

Objectives: To quantify the prevalence and duration of delirium in patients in the intensive care unit (ICU) before and after implementation of the ABCDE bundle.

Methods: Delirium prevalence was defined as the percentage of patients who had at least 1 positive delirium score on the Intensive Care Delirium Screening Checklist (ICDSC) during the ICU stay; delirium duration was the number of days during the ICU stay that a positive ICDSC score was noted.
