Dynamic Multimodal Delirium Warning After Cardiac Surgery
China200 participantsStarted 2026-07-06
Plain-language summary
After heart surgery, up to half of all patients may develop a state of sudden confusion called postoperative delirium. This condition can lead to longer time on a breathing machine, extended stays in the intensive care unit (ICU), and a slower overall recovery. Currently, doctors have no reliable way to predict delirium early enough to take preventive action. This study aims to build a computer-based early warning system. The system will combine continuous, real-time measurements of brain waves (EEG), the oxygen level in the brain, and heart and blood pressure function. It will also include information about each patient's health status. By analyzing all of these signals together, the model is designed to give an alert 1 to 6 hours before delirium might start, giving the care team a window of time to intervene. The study will take place in the ICU at Zhongda Hospital, Southeast University. Adults between 18 and 80 years old who are admitted to the ICU after heart surgery will be invited to participate. All patients will receive the usual standard of care; the study does not test any new treatment. Participation means the investigators will continuously record the brain, oxygen, and heart signals that are already being monitored, and a researcher will regularly assess the patient's thinking and alertness with a simple bedside check.

Inclusion criteria
. Adult patients (18-80 years) admitted to the Department of Critical Care Medicine.
. Underwent cardiac surgery.
. Under multimodal monitoring (including EEG, cerebral oximetry, and invasive arterial blood pressure).
. Signed informed consent.
Exclusion criteria
. Pre-existing dementia, history of psychiatric disorders, or long-term use of antipsychotic medications, preventing accurate assessment of delirium.
. Preoperative severe hepatic or renal insufficiency (Child-Pugh Class C or eGFR \<30 mL/min/1.73 m²).
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Incidence of Postoperative Delirium (POD)
Timeframe: From ICU admission until ICU discharge or Day 7 postoperatively, whichever occurs first.
2
Time to Onset of Postoperative Delirium
Timeframe: From end of surgery until first documented delirium or ICU discharge, up to 7 days.
3
Duration of Postoperative Delirium
Timeframe: From first delirium onset until delirium resolution or ICU discharge, up to 7 days.
