Virtual Reality-based Sensory Stimulation for Delirium Prevention in Intensive Care Units

3. september 2026 opdateret af: Liang Surui, Chinese University of Hong Kong

Virtual Reality-based Sensory Stimulation for Delirium Prevention in Intensive Care Units: A Randomized Controlled Trial

The goal of this clinical trial is to evaluate whether virtual reality (VR)-based sensory stimulation can help prevent delirium in adult intensive care unit (ICU) patients, compared with an active control condition delivering the same nature-based audiovisual content via a tablet. The main questions it aims to answer are:

  1. Does VR-based sensory stimulation delay the time to the first delirium event during ICU stay?
  2. Does VR-based sensory stimulation reduce delirium incidence, duration, and severity?
  3. What are the effects of the intervention on ICU length of stay, duration of mechanical ventilation, cognitive function at 3 months after ICU discharge, and health-related quality of life? Researchers will compare immersive VR-based sensory stimulation with a non-immersive tablet-based active control to assess the added value of immersion beyond the effects of sensory content alone.

Participants will:

  1. Receive either immersive VR-based sensory stimulation or tablet-based sensory stimulation
  2. Receive one 20-minute session per day for up to 3 days during ICU stay Undergo twice-daily delirium assessments during ICU stay Complete follow-up assessments of cognitive function and health-related quality of life at 3 months after ICU discharge

Detaljeret beskrivelse

Delirium is a common acute neurocognitive disorder in critically ill patients and is associated with poor short- and long-term outcomes, including prolonged ICU stay, extended mechanical ventilation, persistent cognitive impairment, and reduced quality of life after discharge. Environmental factors in the ICU, particularly sensory deprivation and excessive noise and light disturbance, are recognized as modifiable contributors to delirium risk.

Conventional sensory stimulation has shown potential to delay delirium onset and reduce delirium severity in ICU patients. However, implementation in routine ICU practice is challenging because intervention delivery may be disrupted by the complex ICU environment and may vary across clinical staff and settings.

This study evaluates a virtual reality (VR)-based sensory stimulation intervention designed to provide immersive visual and auditory input while reducing interference from the ICU environment. The intervention uses a head-mounted display and headphones to deliver standardized nature-based content. An active control condition was selected to receive the same content through a tablet, allowing comparison of immersive versus non-immersive delivery while controlling for the sensory content itself.

This study is a pilot randomized controlled trial conducted in adult ICU patients. Participants are randomly assigned in a 1:1 ratio to either the VR intervention group or the active control group. Both groups receive one 20-minute session daily for up to 3 days during ICU stay. Delirium is assessed twice daily during ICU stay, and participants are followed at 3 months after ICU discharge for cognitive and quality-of-life outcomes. The study is intended to generate preliminary estimates of intervention effects and to inform the design of a future definitive trial.
