ICU Delirium Playbook Training Study for ICU Nurses

Delirium is a common and serious acute neurocognitive disorder among critically ill patients, affecting up to 50% of intensive care unit (ICU) patients and up to 80-90% of those receiving invasive mechanical ventilation. It is associated with increased mortality, prolonged ICU and hospital length of stay, long-term cognitive impairment, higher healthcare costs, and reduced quality of life for patients and their families. Despite the availability of validated screening tools such as the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU), delirium remains underrecognized and undertreated in routine clinical practice, largely because of inadequate healthcare professional education and inconsistent implementation of evidence-based recommendations. Nurses play a central role in the prevention, early detection, and management of delirium, making targeted educational interventions essential to improve clinical practice. The ICU Delirium Playbook is a multimedia educational program developed by the University of California, San Diego, consisting of brief instructional videos and realistic clinical scenarios designed to improve nurses' knowledge and confidence in delirium assessment and management. The aim of this quasi-experimental pre-post study is to evaluate the effectiveness of the ICU Delirium Playbook among intensive care nurses at Pisa University Hospital. The primary objective is to determine whether participation in the educational program improves nurses' knowledge of delirium. Secondary objectives are to evaluate participants' satisfaction with the training, assess changes in clinical attitudes and behaviors related to delirium care, validate the Italian version of the behavioral assessment questionnaire, and explore the impact of the educational intervention on patient outcomes, including the frequency of delirium recognition and the duration of delirium episodes. The study will be conducted in a single center using a pre-intervention and post-
