About this study
Official title: Post-ICU Neurocognitive Performance and Sleep Quality Ratings Following Exposure to a Medical ICU Sleep Quality Improvement Project
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.
Read the 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.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 23 Jun 2011. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Digit span test score (time frame: within 96 hours of Intensive Care Unit (ICU) discharge). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Jun 2011; AzTrials last refreshed its copy on 6 Nov 2026.
