About this study
Sleep disturbances, cognitive reserve, and continuing pain and inflammation are other risk factors contributing to delirium (confusion and agitation) and neurocognitive decline (in the long term) following heart surgery. Investigators aim to test a bundle of sleep optimization, cognitive exercise before surgery, and extended pain relief for 48 hours with intravenous acetaminophen combined with enhanced recovery after surgery protocols (SCOPE bundle). SCOPE will fill significant gaps in evidence by testing the value of a patient and care-provider-focused intervention that can potentially minimize POD and improve outcomes (cognitive \& physical function, sleep quality, pain, depression or anxiety, and survival) important to patients and families.
The SCOPE trial will address many heart surgery outcome-related questions commonly asked by patients:

What can I do to reduce my chances of developing confusion, hallucinations, or delirium after surgery? How can I best prepare before surgery to improve my long-term health and avoid disability? Are there exercises I can participate in that improve my sleep, pain, and mood after surgery? Intellectual pursuits, physical activity, and social interactions support cognitive reserve, while poor health, poor sleep hygiene, poor nutrition, and mental health disease can diminish reserve. Various interventions with different intensities and timing to augment cognitive reserve have been associated with positive outcomes on neuropsychological testing. Adaptive video gaming for as little as 10 hours leads to the maintenance of independence in activities of daily living and sustained improvements in speed of processing, attention, and working memory in older people. Likely through the increased cognitive reserve, perioperative brain exercise aims to protect against morbid cognitive recovery after surgery.
Sleep is vital for memory and cognitive function. Poor sleep traits in older adults that are potentially modifiable, including short/long duration, daytime napping, and associated sleepiness, led to an almost 2-fold increase in delirium risk. Patients will complete an evidence-based course on healthy sleep habits and will complete guided exercises designed to restructure behaviors and thinking. They are encouraged to follow a set of recommendations to improve their sleep (e.g., optimal sleep duration, advice for habits such as daytime napping, maintaining a regular sleep schedule, avoiding caffeine, regular daylight exposure, dimming lights or electronics and relaxation and thought exercises for optimal sleep); many of these sleep behaviors have been strongly linked to increased risk for cognitive decline. Investigators propose that sleep optimization before AND after (an established best practice sleep bundle) surgical insult will contribute to cognitive reserve leading to decreased delirium risk and key patient-centered outcomes (postoperative sleep, pain, cognition, mood, and survival).
Inadequate pain relief and opioids are both risk factors for delirium. Surgery on the chest is a significant pain source. Approximately 30-75% of patients suffer from moderate to severe pain in the postoperative period. Almost half of the patients have severe pain at rest, and three-quarters have severe pain during coughing and movement. Pain and inflammation are closely biochemically linked.
Sleep, brain exercise, and adequate pain control with opioid-sparing can be additive or synergistic interventions to prevent delirium following heart surgery.
Investigators propose three specific aims by conducting a 1:1 randomized controlled trial in 406 heart surgery patients 60 or older undergoing heart surgery. They will be administered perioperative sleep optimization, brain exercise training, and intravenous acetaminophen over 48 hours. A trained expert will administer the sleep and cognitive exercise protocols at least two weeks before surgery. This expert will handhold the patients for two weeks until the surgery. Thus, the gains made before surgery with better sleep quality and improved brain reserve will be sustained with postoperative pain control to lower the ongoing inflammation. Through this trial, investigators will evaluate if the SCOPE bundle can reduce 1) in-hospital delirium, 2) long-term (one, six, and twelve months) cognitive, physical, and self-care function, and 3) barriers to implementation of this bundle.
Currently, no options are routinely available to patients to optimize their sleep and cognition before cardiac surgery. The proposed research is significant because it will be the first to test the bundled behavioral intervention approach (sleep optimization, brain exercise) before surgery with extended, scheduled pain management with non-opioids following surgery. The SCOPE trial will yield relevant and immediately actionable data to improve care for over 900,000 adults in the U.S. each year.
Read the detailed description
Background and Significance: Cardiac surgery is performed on more than 900,000 adults in the U.S. each year, with significant cognitive consequences for individuals and society. Postoperative delirium (POD) is a common and costly complication after cardiac surgery. POD prevention is a priority for patients, families, and clinicians. Cognitive reserve is a significant contributor to POD risk. Despite many successes of Enhanced Recovery After Surgery (ERAS) initiatives to improve patient outcomes, incorporating cognitive-protective strategies into protocols remains limited by lack of evidence. The SCOPE Trial (Sleep, Cognition, and Pain bundle vs. ERAS-cardiac (enhanced recovery after cardiac surgery) for POD) will fill significant gaps in delirium prevention evidence by testing the value of a patient and care-provider-focused intervention that can potentially minimize POD. Study Aims: Investigators hypothesize that the intervention bundle (multicomponent combination of non-pharmacological (pre- and post-operative sleep optimization and cognitive exercise) and pharmacological (extended postoperative opiate-sparing pain control with intravenous (IV) acetaminophen for 48 hours) will decrease POD incidence and improve outcomes compared to standard ERAS protocols alone. Investigators hypothesize that the bundle increases 1) resistance to circadian disruption, 2) improved neuronal function, and 3) cognitive reserve. Investigators will determine differences in incidence, duration, and severity of POD (Specific Aim 1) and postoperative functional status, cognition, sleep, pain, and mood between study groups 1, 6, and 12 months following cardiac surgery (Specific Aim 2). Investigators will evaluate implementation barriers for our multicomponent SCOPE bundle and acceptability and feasibility (Specific Aim 3). Study Description: The SCOPE trial is a multicenter randomized, multi-component, superiority trial in older patients (at least 60 years) undergoing non-emergent coronary artery bypass grafting with or without valves or isolated valve surgery with 1:1 allocation using permuted block randomization of variable block sizes 2, 4, and 6 (406 patients equally divided at four tertiary care centers across the U.S (Beth Israel Deaconess Medical Center (n=106), Massachusetts General Hospital (n=100), Columbia University (n=100) and Ohio State University Medical Center (n=100). Patients with alcohol abuse, hypersensitivity to acetaminophen, and severely depressed left ventricular ejection fraction (<30%) will be excluded. Enrolled participants will receive either the SCOPE regimen at least 2 weeks before surgery and scheduled postoperative acetaminophen analgesia for the first 48 hours (plus ERAS)) or the standard-of-care ERAS regimen only.
- Investigators will use a shorter form of our existing clinical CBT program for insomnia (4 hybrid sessions), delivered over two weeks before cardiac surgery to optimize sleep. Investigators will also check in with patients to establish sleep preferences during postoperative recovery, e.g., usual sleep schedule, noise reduction aids, temperature, light, and music preferences. Key components that can be effectively taught and implemented quickly based on our clinical experience include, stimulus control, relaxation techniques, sleep hygiene education, and cognitive restructuring to address sleep-related anxiety misconceptions and relaxation techniques. The Control group will be given a sleep hygiene education tip sheet only.
- To optimize cognitive function, intervention patients will be asked to complete 10 hours of preoperative tablet-based brain exercise using gaming software focused on memory, speed, attention, flexibility, and problem-solving. This has been designed and integrated with the above sleep intervention to streamline patient experience and decrease burden and maximize retention. A prehabilitation specialist will deliver these interventions.
- SCOPE-bundle patients will receive eight doses of IV acetaminophen over 48 hours (compared to standard pain management for ERAS includes three doses of IV acetaminophen over 24 hours).
The primary study outcome is POD incidence within seven days or until discharge following cardiac surgery, whichever occurs first, as determined by the Confusion Assessment Method (CAM) or CAM-ICU, supplemented with charted delirium. Secondary outcomes include POD duration (number of days), severity (CAM-Severity), length of postoperative stay (days), and mortality (30 days). Additional secondary outcomes assessed up to 12 months post-surgery include (pain (analgesia requirements, Verbal Rating Pain Scale), mood (Geriatric Depression Scale), functional recovery (Instrumental Activities of Daily Living and Medical Outcomes Study Short Form 12), and sleep quality (Pittsburgh Sleep Quality Index and objective metrics via sleep diary, and actigraphy). Secondary outcomes of determinants of bundle implementation, feasibility, and acceptability of implementation will be evaluated within the integrated Promoting Action on Research Implementation in Health Services (i-PARIHS) framework at the start and conclusion of the study

What is being measured
The primary outcome is the main question the study is designed to answer.
Delirium Incidence
Positive CAM (Confusion Assessment Method) evaluation. : The Confusion Assessment Method (CAM) is a standardized evidence-based tool that enables non-psychiatrically trained clinicians to identify and recognize delirium quickly and accurately in both clinical and research settings. The CAM includes four features found to have the greatest ability to distinguish delirium from other types of cognitive impairment. Each feature is scored as present or absent. Delirium is considered present based on the CAM diagnostic algorithm: presence of (acute onset or fluctuating course -AND- inattention) -AND EITHER- (disorganized thinking or altered level of consciousness)
Measured: Seven days following cardiac surgery or until discharge of patient from the hospital. This can be anywhere from 3-7 days post operatively
Secondary outcomes (2)
Severity of Delirium
CAM- S (Confusion Assessment Method- Severity) score. A delirium severity rating scale based on the additive scoring of symptoms rated in the CAM long form (Confusion Assessment Method). The CAM-S is intended to be used in addition to the original CAM algorithm. The scale for CAM-S is from 0-19 with 0 being the least severe and 19 being the most severe.
Measured: Seven days following cardiac surgery or until discharge of patient from the hospital. This can be anywhere from 3-7 days post operatively
Duration of Delirium
The total number of days patient is CAM (Confusion Assessment Method) positive following cardiac surgery
Measured: Seven days following cardiac surgery or until discharge of patient from the hospital. This can be anywhere from 3-7 days post operatively

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

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.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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 Balachundhar Subramaniam, MD/MPH (7814750572, bsubrama@bidmc.harvard.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Delirium Incidence (time frame: Seven days following cardiac surgery or until discharge of patient from the hospital. This can be anywhere from 3-7 days post operatively). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 15 Apr 2026.
