About this study

Official title: Sleep Disruption and ICU Delirium: Delirium Assessment and Monitoring Combined With the Evaluation of Sleep Using the Sedline Brain Function Monitor.

The investigators will perform a prospective, cohort study of 100 older intensive care unit (ICU) patients, to investigate the association between sleep disruption and ICU delirium.

Read the detailed description

Delirium and sleep disruption are both common in the intensive care unit (ICU). Delirium is a state of acute confusion, experienced especially by older adults admitted to the hospital, with the potential to adversely impact patients' outcome. Of hospitalized patients, the highest rate of delirium occurs in elderly patients in the ICU. Development of ICU delirium is associated with longer ICU and hospital length of stay, significantly higher risk of functional decline, loss of independent living, and increased mortality. Previous studies have focused on describing the clinical manifestations, risk factors and outcomes of ICU delirium; yet, the contribution of sleep timing, as well as its quality and quantity, to the development of delirium, has not previously been rigorously investigated. Sleep disturbance, including changes in sleep patterns and architecture, and decreased quality of sleep are commonly observed in older subjects. In the ICU, environmental factors (such as noise levels and continuous ambient light) and health care practices (such as frequent performance of medical procedures and tests) further contribute to sleep disruption in the critically ill older patients. Additionally, many sedative and analgesic agents potently suppress slow wave sleep. In preliminary data acquired from ICU patients, the investigators have observed that fragmented sleep is prevalent due to frequent arousals and awakenings, and that sleep architecture is altered with an increase in light sleep, and a decrease in restorative slow wave sleep. Despite the common occurrence of both ICU delirium and sleep disruption, it is not known whether sleep disruption increases the risk of developing delirium in the critically ill older patients. In this exploratory study, the investigators propose to test the hypothesis that the severity and duration of sleep disruption is an independent predictor of the onset and duration of ICU delirium in a cohort of older ICU patients. The investigators will measure sleep disruption using continuous processed electroencephalography and measure ICU delirium using a well-validated and reliable standardized instrument. Results from this study will inform the contribution of sleep disruption in the development of ICU delirium in the older critically ill patients.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. ICU delirium

    ICU delirium will be measured using the CAM-ICU. This measurement will be done twice daily.

    Measured: Daily measurement during study

Secondary outcomes (5)
  1. Intensive Care Unit (ICU) length of stay

    The day of admission to the ICU until the day of discharge from the ICU.

    Measured: Assessed at discharge from ICU

  2. Hospital Length of Stay

    This is the persons length of stay in the hospital, from admission date until discharge date.

    Measured: Assesses at discharge from hospital

  3. ICU mortality

    We will collect data on mortality during the stay in the Intensive Care Unit

    Measured: Assessed at discharge from ICU

  4. Hospital mortality

    We will assess the mortality during the hospital stay.

    Measured: Assessed at discharge from hospital

  5. One year mortality

    We will assess mortality at one year from hospital admission.

    Measured: Assessed at 1 year from admission to hospital

Questions about this trial

What is this clinical trial studying?

An observational study of Delirium and Sleep Disorders, Circadian Rhythm, run by University of California, San Francisco at 1 site in United States.

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 1 inclusion and 4 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 15 Jul 2015. 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?

ICU delirium (time frame: Daily measurement during study). 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 15 Jul 2015.
