About this study
The goal of this nonrandomized, quasi-experimental clinical trial is to evaluate whether an intelligent audiovisual intervention can prevent delirium and reduce delirium severity, agitation, and pain among adults aged 55 years or older admitted to an emergency intensive care unit (EICU). The main questions it aims to answer are:
Does the intelligent audiovisual intervention reduce the incidence and severity of delirium compared with routine care? Does the intervention improve agitation and pain scores compared with routine care?
Read more
Researchers will compare participants receiving the intelligent audiovisual intervention plus routine care with participants receiving routine care alone. Participants will be assigned according to the week of EICU admission: those admitted during odd-numbered weeks will receive the intervention, while those admitted during even-numbered weeks will receive routine care.
Participants in the intervention group will:
View a structured audiovisual program containing a prerecorded message from a family member, current date and weather information, and images of the area surrounding the hospital.
Receive the intervention for 2 minutes per session, 3 times daily for 2 consecutive days, beginning within 24 hours after EICU admission.
Participants in both groups will undergo assessments of delirium, agitation, and pain 3 times daily for 2 consecutive days. Delirium incidence and severity will be assessed using the Confusion Assessment Method for the Intensive Care Unit-7 (CAM-ICU-7). Agitation will be evaluated using the Richmond Agitation-Sedation Scale (RASS), and pain will be assessed using either the Numerical Rating Scale (NRS) or the Face, Legs, Activity, Cry, and Consolability (FLACC) scale.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Intelligent Audiovisual InterventionBehavioural
A structured, personalized audiovisual intervention designed to provide cognitive reorientation and emotional support. The program incorporates person, time, and place orientation cues, including a prerecorded message from a family member using the participant's name and familiar language; current date, weather, and temperature information presented through automated audiovisual content; and images of the area surrounding the hospital. Participants will receive the intervention for 2 minutes per session, 3 times daily (at 7:00 AM, 5:00 PM, and 9:00 PM) for 2 consecutive days, beginning within 24 hours after admission to the emergency intensive care unit. The intervention will be provided in addition to routine care.
| Study group | Role | What they receive |
|---|---|---|
| Intelligent Audiovisual Intervention | Experimental | Participants will receive routine care plus a structured intelligent audiovisual intervention beginning within 24 hours after admission to the emergency intensive care unit. The audiovisual program includes a prerecorded message from a family member, current date and weather information, and images of the area surrounding the hospital to provide cognitive orientation cues and emotional support. The intervention will be delivered for 2 minutes per session, 3 times daily (at 7:00 AM, 5:00 PM, and 9:00 PM) for 2 consecutive days. Participants will also receive routine family visiting twice daily. Receives: Behavioral: Intelligent Audiovisual Intervention |
| Routine Care | No intervention | Participants will receive routine care without the intelligent audiovisual intervention. Routine care includes standard medical and nursing care and family visiting twice daily, at 11:00 AM and 7:00 PM, for 1 hour per visit. Participants will undergo the same assessments of delirium, agitation, and pain as those in the experimental arm. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of Delirium Assessed Using the CAM-ICU-7
Delirium will be assessed using the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU-7). The outcome will be reported as the percentage of participants with at least one positive CAM-ICU-7 assessment during the 2-day assessment period.
Measured: From baseline through the end of Day 2; assessed 3 times daily
Change From Baseline in Delirium Severity Assessed Using the CAM-ICU-7
Delirium severity will be measured using the CAM-ICU-7. Total scores range from 0 to 7, with higher scores indicating greater delirium severity. Scores of 0 to 2 indicate no delirium, 3 to 5 indicate mild to moderate delirium, and 6 to 7 indicate severe delirium. Changes from baseline will be evaluated across the scheduled assessments.
Measured: Baseline through the end of Day 2; assessed 3 times daily
Secondary outcomes (2)
Change From Baseline in Richmond Agitation-Sedation Scale Score
Agitation and sedation will be assessed using the Richmond Agitation-Sedation Scale (RASS). Scores range from -5 to +4. A score of 0 indicates that the participant is alert and calm, positive scores indicate increasing agitation, and negative scores indicate increasing levels of sedation.
Measured: Baseline through the end of Day 2; assessed 3 times daily
Change From Baseline in Pain Intensity Score
Pain intensity will be assessed using the 11-point Numerical Rating Scale (NRS) for participants able to self-report or the Face, Legs, Activity, Cry, and Consolability (FLACC) scale for participants unable to communicate reliably. Both scales range from 0 to 10, with higher scores indicating greater pain intensity.
Measured: Baseline through the end of Day 2; assessed 3 times daily

Questions about this trial
What is this clinical trial studying?
A study testing Intelligent Audiovisual Intervention in people with Delirium Confusional State, run by Taipei Veterans General Hospital, Taiwan.
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 6 inclusion and 8 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: opening soon, as of the sponsor's last update on 20 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Li Fang-Yu (+886 966-914-515, fylee6@vghtpe.gov.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of Delirium Assessed Using the CAM-ICU-7 (time frame: From baseline through the end of Day 2; assessed 3 times daily). The study lists 2 primary outcomes in all. 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 NCT07776002, which also lists 4 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 20 Aug 2026.
