About this study

The purpose of this multicenter randomised controlled trial is to investigate if circadian light at the patients bedside (using Philips HealWell system, CE marked)significantly reduces prevalence of delirium in mechanically ventilated intensive care unit patients.

Read the detailed description

Patients, who are randomly assigned to the "Lightening arm" will have the circadian light for the whole ICU stay. Light levels at the patients bedside will be measured continuously: embedded light sensors provide irradiance and luminous lux recordings in red, green, and blue color bands and a white light measurement in lux

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Circadian lightOther

    Artificial ceiling lighting throughout the day will be provided by the Philips HealWell system, CE marked, which is able to deliver varying light levels and warmer or cooler light according to the time of the day (circadian light). Emergency or examination lighting can be set on demand as circumstances require.

    Lighting conditions at the patients bedside will be characterized by transformations on the time-series of light levels as measured by a luxmeter. The following metrics will be used for lighting characterization in a period of 24h: mean levels of bright and dark periods, contrast between bright and dark periods, clustering of bright and dark periods, and circadian variation.

What is being measured

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

    Dekirium will be measured with the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU)

    Measured: Participants will be followed for the duration of Intensive Care Unit stay, an expected average of 5 days

Secondary outcomes (21)

    Measured: Participants will be followed for the duration of Intensive Care Unit stay, an expected average of 5 days

  2. Severity of delirium

    Severity of delirium will be measured with the help of the Intensive Care Delirium Screening Checklist (ICDSC)

    Measured: Participants will be followed for the duration of Intensive Care Unit stay, an expected average of 5 days

  3. Duration of delirium

    Measured: Participants will be followed for the duration of Intensive Care Unit stay, an expected average of 5 days

  4. Prevalence of subsyndromal delirium (SSD)

    Measured: Participants will be followed for the duration of Intensive Care Unit stay, an expected average of 5 days

  5. Severity of anxiety

    Measured: Participants will be followed for the duration of Intensive Care Unit stay, an expected average of 5 days

  6. Cognitive Dysfunction

    Measured: ICU admission, ICU discharge, 6 months after hospital discharge, 12 months after ICU discharge

  7. Post-Traumatic Stress Disorder (PTSD)

    Measured: 6 and 12 months after hospital discharge

  8. Sleep quality

    Measured: In the night, starting 48 hours after ICU admission

  9. ICU length of stay

    Measured: Participants will be followed for the duration of Intensive Care Unit stay, an expected average of 5 days

  10. Duration of mechanical ventilation

    Measured: Participants will be followed for the duration of Intensive Care Unit stay, an expected average of 5 days

  11. Hospital length of stay

    Measured: Participants will be followed for the duration of Intensive Care Unit stay, an expected average of 4 weeks

  12. Level of sedation

    Measured: Participants will be followed for the duration of Intensive Care Unit stay, an expected average of 5 days

  13. Pain level

    Measured: Participants will be followed for the duration of Intensive Care Unit stay, an expected average of 5 days

  14. Amount of administered opioids

    Measured: Participants will be followed for the duration of Intensive Care Unit stay, an expected average of 5 days

  15. Amount of administered benzodiazepines

    Measured: Participants will be followed for the duration of Intensive Care Unit stay, an expected average of 5 days

  16. Amount of administered sedatives

    Measured: Participants will be followed for the duration of Intensive Care Unit stay, an expected average of 5 days

  17. Amount of administered antipsychotics

    Measured: Participants will be followed for the duration of Intensive Care Unit stay, an expected average of 5 days

  18. Mortality

    Measured: ICU discharge, hospital discharge, 6 months after hospital discharge, 12 months after hospital discharge

  19. Light levels (lux) Light levels (lux)

    Measured: Participants will be followed for the duration of Intensive Care Unit stay, an expected average of 5 days

  20. Light frequencies

    Measured: Participants will be followed for the duration of Intensive Care Unit stay, an expected average of 5 days

  21. Noise levels (decibel)

    Measured: Participants will be followed for the duration of Intensive Care Unit stay, an expected average of 5 days

Questions about this trial

What is this clinical trial studying?

A study testing Circadian light in people with Delirium, run by Charite University, Berlin, Germany at 1 site in Germany.

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 16 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: withdrawn, as of the sponsor's last update on 19 Oct 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 Germany. 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 was withdrawn before enrolling participants, so there are no results.

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?

Prevalence of delirium (time frame: Participants will be followed for the duration of Intensive Care Unit stay, an expected average of 5 days). 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 19 Oct 2015.
