A pilot study on delirium in the intensive care unit: a creative inquiry project with undergraduate nursing students.

Introduction: Delirium continues to be a major issue in intensive care units (ICUs). Sedation and lack of rapid eye movement (REM) sleep could be important factors in the development of delirium. Improper sedation may interfere with a patient's sleep pattern, specifically time spent in REM sleep, and could be a contributor to the development of delirium.
