Prevention of Delirium in ICU Using Multimodal Interventions
Study Details
Study Description
Brief Summary
This study was designed to evaluate the impact of non-pharmacological multimodal interventions including ongoing orientation, sensory correction, setting of familiar circumstance and promotion of sleep enviromnet for prevention of delirium in intensive care unit.

Detailed Description
Delirium significantly increases not only the length of the intensive care unit stay and overall mortality, but also the likelihood of persistant cognitive impairment after recovery. However there is no definitive treatment for delirium, thereby it is important to prevent delirium before it occur. Researches also have focused on the prevention of delirium or the reduction of duration of delirium.
Several studies evaluated the effect of non-pharmacological treatment, such as improvement of orientation, prevention of sensory deprivation, active pain control and prevention of dehydration, to reduce the occurrence of delirium and the results were inconsistent depending on the patients included. However, there have been no randomized clinical trials that have tested the effect of prevention of delirium by applying non-pharmacological multimodal approaches in the intensive care unit for Korean patients.
A randomized controlled trial was planned to evaluate the impact of on-pharmacological multimodal interventions including ongoing orientation, sensory correction, setting of familiar circumstance and promotion of sleep enviromnet for prevention of delirium in intensive care unit in Korea.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Multimodal therapy group Continuous regional cerebral oxygen saturation and processed electroencephalogram (EEG) are monitored. Multimodal therapy with conventional care are provided to prevent delirium. Ongoing orientation: 3 times per day Sensory correction: the hearing device and the glasses are supplied. Cognitive stimulation: a portable monitor is used to provide visual stimulation, and a directional speaker is used to avoid disturbing the alarm of the patient's life supportimng system. Sleep promotion: the lights are turned off from 10 pm to 7 am, and the indirect light source is used if necessary. |
Other: Multimodal therapy for prevention of delirium
Multimodal therapy for prevention of delirium
|
| No Intervention: Conventional care group Continuous regional cerebral oxygen saturation and processed electroencephalogram (EEG) are monitored. Conventional care: If sedation is required, dexmedetomidine is considered as the first-line sedative drug. The sedation is interrupted daily and the possibility of awakening is assessed. Pain with NRS score above 3, is controlled with opioid. For patients with Richmond Agitation Sedation Scale (RASS) -4 or -5, possible items are provided. |
