This quality improvement project was implemented to determine non-pharmacological sleep interventions' impact on delirium incidence in a medical/surgical intensive care unit (ICU). The Confusion Assessment Method-ICU (CAM-ICU), a validated tool used to detect delirium, was used to assess patient mental status both before and after project implementation. This tool is utilized in the electronic medical record as a daily documentation tool for delirium tracking but has not been used to facilitate interventions for delirium. The literature has shown that through the use of non-pharmacologic sleep promotion and interventions, delirium diagnosis can be delayed or avoided. This can lead to decreased morbidity and mortality and better patient outcomes. The CAM-ICU tool was used on every eligible ICU patient, every shift, for eight weeks, unless restricted by their medical provider. Non-pharmacological sleep interventions were implemented to assess the impact on a patient’s CAM-ICU score. The pre-implementation delirium rate was derived from CAM- ICU positive scores on ICU patients between January 1, 2023, and December 31, 2023. Data was collected for eight weeks post-implementation. Implementation of non-pharmacological sleep interventions had a statistically significant impact on the incidence of delirium as measured by CAM-ICU.
