NCT07051096 · NOT YET RECRUITING
Responsive Nature-Driven Imagery to Reduce Delirium After Cardiac Surgery
This trial tests a device called MindfulGarden, which shows calming nature imagery that responds to a patient's body signals. Researchers want to know if it is practical after open-heart surgery, and whether it reduces delirium, agitation, and the need for sedating medications. Patients are randomized to use it or not. The phase is not applicable, which is common for device studies.
You may qualify if
- Planned open-heart cardiac surgery (e.g. coronary artery bypass grafting, valve replacement surgery);
- Able to understand study procedures and provide informed consent in English;
- At least one delirium risk factor: 1) Age less than 65yrs; 2) History of delirium; 3) History of stroke/TIA; 4) Known cognitive impairment; 5) Depression requiring medication.
You're excluded if
- Severe pre-existing cognitive impairment (Montreal Cognitive Assessment [MOCA6]\<10)
- Uncorrected visual impairment;
- Significant impairment from psychiatric disease;
- Enrolment in another clinical trial which may interfere with the study outcome measures.
