Delirium is a complex neuropsychiatric syndrome with an acute onset and fluctuating course which is presented in 15 to 20% of patients admitted to general wards. It is a potentially life - threatening complication which can be prevented. It is the objective of this randomized controlled trial to evaluate whether a multicomponent environmental intervention could reduce the incidence of delirium in a general medical ward.

Arms Assigned Interventions
Placebo Comparator: Standard Care
Delirium management defined by the attending physician.
Other: Standard Care
Delirium management by the attending physician's preferences.
Experimental: Environmental Intervention Other: Environmental Intervention
The environmental intervention consisted of daily reorientation, avoidance of sensorial deprivation, longer visiting hours, the availability of a clock, a calendar and the presence of familiar objects in the room.

Detailed Description:

A total of 287 patients 65 years of age or older who had been admitted to a general medicine ward and who were at risk of delirium were studied. Eligible patients were randomized to a multicomponent environmental intervention or standard care. Both groups were well balanced in patients characteristics and followed during the full hospital stay by a group trained in the application of the confusion assessment method to detect incident delirium.
