Standardized Sleep Bundle for Cardiac Surgery Patients

Canada20 participantsStarted 2026-03-02

Plain-language summary

The goal of this clinical trial is to evaluate the feasibility of using a standardized sleep bundle in adults undergoing cardiac surgery. The main questions it aims to answer are: 1. Can eligible participants be recruited and retained in the study? 2. Can participants follow the study procedures, including using sleep aids and completing daily assessments? 3. Can sleep and other clinical data be reliably collected during the hospital stay? Researchers will compare participants who receive the sleep bundle to participants who receive usual postoperative care. Participants will: * Use non-drug sleep aids, including a sleep mask, ear plugs, and a noise machine (sleep bundle group only). * Take sleep medications if needed, following a stepwise protocol (sleep bundle group only). * Complete daily sleep assessments using the Richards-Campbell Sleep Questionnaire (RCSQ). * Wear a Fitbit device at night to track sleep. * Follow usual postoperative care routines (control group) The study will also collect and describe data on sleep duration, nighttime awakenings, subjective sleep quality, incidence of postoperative delirium, and hospital length of stay to inform the design of a future larger trial.

Exclusion Criteria: * Emergent surgery. * Severe renal or hepatic impairment (creatinine clearance (CrCl) \<30 mL/min, Chronic Kidney Disease (CKD) stage ≥4, cirrhosis, Alanine Transaminase (ALT) ≥ 3 × upper limit of normal (ULN)). * Sleep apnea. * Restless leg syndrome (RLS). * Insomnia with chronic use of pharmacological sleep aids prior to admission (trazodone, benzodiazepines, zopiclone, mirtazapine, quetiapine, tricyclic antidepressants \[nortriptyline, amitriptyline, doxepin\]). * Prior use of a monoamine oxidase inhibitor in the past 14 days. * Corrected QT Interval (QTc) \> 500ms / history of prolonged QTc, Torsade de points or ventricular tachycardia. * History of dementia, alcohol, or opioid use disorder. * Documented or previous intolerance to melatonin, trazodone, or quetiapine. Unable to provide informed consent. Run-in Period Exclusions: After enrolment and before randomization, participants will be monitored for specific postoperative criteria. Those meeting any of the following criteria will be withdrawn prior to randomization. * Radial artery harvest required (unable to place Fitbit device on the wrist contralateral to the arterial monitoring line). * Prolonged intubation or sedation (\> 48 hours) post-surgery. * Major intra- or early postoperative complications (stroke, transient ischemi…

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.
