Intensive Care Unit (ICU) Sleep Quality and Neurocognitive Performance

This study has been completed.
Information provided by:
Johns Hopkins University Identifier:
First received: February 2, 2010
Last updated: June 22, 2011
Last verified: December 2009
The purpose of this study is to understand patients' neurocognitive performance shortly after discharge from the Medical Intensive Care Unit (MICU) and the potential effect of sleep quality in the MICU on those neurocognitive outcomes. The investigators hypothesize that post-ICU neurocognitive function and patient overall ICU sleep experience will improve through a pre-existing MICU sleep improvement initiative.

Arms Assigned Interventions
No Intervention: Baseline
Post-Intensive Care Unit (ICU) neurocognitive testing and sleep survey performed on patients exposed to ad-lib Medical ICU environment.
Experimental: Sleep Promotion Group
Post-ICU neurocognitive testing and sleep survey performed on patients exposed to interventions in the pre-existing MICU sleep quality improvement project.
Behavioral: Sleep promoting interventions
MICU staff will implement multi-faceted, staged sleep promoting interventions as part of a pre-existing sleep quality improvement project.

Detailed Description:
Despite decades of scientific interest in evaluating sleep among critically ill patients, little is known about the effects of intensive care unit (ICU)-associated sleep disturbances on patient outcomes. Furthermore, few interventions have been rigorously evaluated to demonstrate efficacy in improving sleep in the ICU and associated patient outcomes. Post-ICU neurocognitive test performance data from this study will be linked to a pre-existing Quality Improvement (QI) project for patient sleep in the MICU. We hypothesize that patients' post-ICU neurocognitive performance (delirium status, attention, short-term memory, processing speed, and executive function) will positively correlate with scores from a previously-published Sleep in the Intensive Care Unit Questionnaire. In addition, we hypothesize that both neurocognitive performance and the Sleep in the Intensive Care Unit Questionnaire will improve during the multi-stage MICU-wide sleep QI project. Our project will provide valuable empirical evidence to help support guidelines for promoting sleep in the ICU setting.
