About this study
The objective of this study is to determine the incidence of delirium in adults patients who are admitted at the critical care unit of a Dutch University Hospital.
The primary aim is to determine the incidence of delirium and to determine risk factors for this group of patients to develop a prediction model.
A secondary aim is to find differences between delirious patients and non-delirious patients on different aspects of diagnostics, treatment and care, outcome, length of stay, and inflammation.
According to Dutch law, the need to obtain informed consent was waived by the Committee on Research Involving Human Subjects (CMO) of Nijmegen for this observational study (2007/283).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| delirious patients | minimal one positive CAM-ICU score during ICU admission | |
| non-delirious patients | without any positive CAM-ICU scores during ICU admission |
What is being measured
The primary outcome is the main question the study is designed to answer.

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 3 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 31 Aug 2010. 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 Netherlands. 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?
delirium (time frame: during admission at the critical care). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00604773, which also lists 3 linked publications.
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 31 Aug 2010; AzTrials last refreshed its copy on 8 Nov 2026.
