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.
| Study group | Role | What they receive |
|---|---|---|
| Standard light | No intervention | In this arm patients receive standard lightening conditions |
| Ciradian light | Experimental | In this arm patients receive artificial ceiling light (circadian light) at the bedside. Receives: Other: Circadian light |

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The record says: withdrawn, as of the sponsor's last update on 19 Oct 2015.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.
