Haloperidol is prescribed in high risk ICU patients concerning delirium (50% or more chance to develop delirium detected with the delirium prediction model PRE-DELIRIC, or patients with history of dementia or alcohol abuse)since the delirium protocol is changed and haloperidol is added as a prevention treatment we are gathering information what the effect is on several aspects of delirium

Further study details as provided by Radboud University:

Primary Outcome Measures:
  • Delirium incidence [ Time Frame: one year ] [ Designated as safety issue: Yes ]
    Delirium is diagnosed as minimal one positive CAM-ICU screening during complete ICU admission. Incidence rate is compared with historical cohort data

Secondary Outcome Measures:
  • duration of delirium days on mechanical ventilator Length of stay in the ICU and in-hospital in-hospital mortality incidence of unplanned removal of tube incidence of delirium subtypes [ Time Frame: one year ] [ Designated as safety issue: Yes ]
    measured prospectively and determined in a CRF and compared with historical cohort data

  • Effect haloperidol on biomarkers [ Time Frame: one year ] [ Designated as safety issue: No ]
    Biomarkers are measured in patients with high risk for delirium which are preventively treated with haloperidol

Enrollment: 650
Study Start Date: August 2010
Study Completion Date: October 2011
Primary Completion Date: August 2011 (Final data collection date for primary outcome measure)
Haloperidol prevention group
ICU patients with a high risk for delirium who are treated with haloperidol for preventive reason.
Control group
Historical cohort group of patients (2008-2009)with a determined risk of 50% or more for delirium who were not treated with haloperidol for preventive reason.

Detailed Description:

Measurement the effect of haloperidol as delirium preventive intervention. Determining effect on:

- delirium incidence in the ICU - different subtypes of delirium - delirium free days in 28 days - days on the ventilator - length of stay on the ICU and In-Hospital - 28-day mortality - incidence of unexpected removal of tubes, and effect between different groups of patients. Safety of haloperidol concerning QT-time, extrapyramidal symptoms.

Data are compared with the data of a historical cohort
