AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
Aged 18 years or above who were scheduled for elective cardiac surgery with cardiopulmonary bypass
Exclusion Criteria:
Patients undergoing congenital heart disease repair surgery or surgeries necessitating deep hypothermic circulatory arrest were excluded.
Patients with a history of schizophrenia, epilepsy, Parkinson's disease, myasthenia gravis, or neurosurgery were also excluded.
Patients with a preoperative Mini - Mental State Examination (MMSE) score less than 24 , or those unable to communicate due to coma, severe dementia, or language barriers were excluded.
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.
1This study has already been completed — does that mean results are available, and if so, what did they find about the link between preoperative sleep quality and the risk of postoperative delirium or acute kidney injury?
2Since this trial was observational and focused on correlation rather than treatment, would knowing my own preoperative sleep patterns actually change how my surgical team manages my care or monitors me after surgery?
3If poor preoperative sleep is linked to a higher risk of delirium and kidney problems after surgery, are there steps I should be taking in the weeks before my operation to improve my sleep, and would my doctor recommend any specific interventions?
4Given that this study looked at both delirium and acute kidney injury together as a combined outcome, does my personal health history — for example, any existing kidney issues or cognitive concerns — make me more likely to be at risk for either of these complications after surgery?
5Are there other completed or ongoing studies my doctor is aware of that have moved beyond correlation and are testing actual ways to reduce postoperative delirium and kidney injury for patients with sleep problems before surgery?

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.
