The goal of this clinical trial is to learn if changing sleep behaviour can improve sleep health in patients undergoing prehabilitation before elective surgery. Prehabilitation is the use of exercise, nutrition, and psychological support before surgery to improve recovery from surgery. The main questions it aims to answer are: Does changing sleep behaviour improve sleep before surgery? Does changing sleep behaviour improve recovery after surgery? Researchers will compare participants who receive sleep support with participants who do not receive sleep support to see if it improves sleep health and recovery from surgery. Participants will be asked to attend 4 meetings with the research team to learn how they can improve their sleep. They will use questionnaires, a diary, and a wearable tracker to record their sleep.
Sample Size: N = 154 Study Population: Patients participating in UHN's Prehabilitation Program. Participants will be excluded if they are participating in prehabilitation entirely remotely (i.e., no in-person visits), have an existing sleep disorder, are a shift worker, have travel plans outside of usual time zone, or have a cognitive disability that limits answering questionnaires or adhering to the intervention. Study Design: Randomized trial with outcome assessors blinded to group allocation. Primary Objective: Measure the effect of a personalized sleep prehabilitation (PSP) in addition to standard of care prehabilitation on participant sleep health compared to standard of care prehabilitation alone. Secondary Objective: To measure the effect of the PSP versus standard of care prehabilitation on other outcomes including clinical outcomes, patient-reported outcomes, and physical fitness. Endpoints of the study: Self-reported sleep health via the Pittsburgh Sleep Quality Index (PSQI; primary outcome). Other sleep health outcomes include the insomnia severity scale (ISI), STOP-BANG questionnaire, Restless Leg Syndrome Diagnostic Index, sleep diary, Global Sleep Assessment Questionnaire (GSAQ), and sleep self-efficacy scale. Clinical outcomes include hospital length of stay and surgical complications. Anthropometric and physical fitness outcomes include: body mass index, bioelectrical impedance analysis (lean mass and fat mass), waist circumference, muscular fitness, aerobic fitness, and functional capacity. Device measured outcomes include sleep, physical activity, resting heart rate, and heart rate variability via a wrist-worn activity tracker. Analysis: Descriptive statistics will be used to characterize participant characteristics. The primary analysis will be an ANCOVA to detect significant differences in PSQI between groups at the preoperative timepoint while controlling for baseline scores. The secondary analysis will be a linear mixed effect model to derive point estimates for effectiveness markers (primary and secondary) at each timepoint, comparing between- and within- group differences at each timepoint. Means and 95% CI will be reported. Impact: The proposed study will be the first to explore the effect of a PSP in addition to standard-of-care prehabilitation service on sleep health.

Sleep prehabilitation will consist of usual care prehabilitation (exercise, nutritional support, psychosocial support, education, smoking cessation support, and/or medical care) with the addition of sleep support. This support will consist of: * Brief behavioural treatment for insomnia * Sleep hygiene * Behaviour change support (e.g., goal-setting, use of a wearable tracker to modify behaviour)
Exercise, nutritional support, psychosocial support, education, smoking cessation support, and/or medical care delivered by regulated health professionals included Kinesiologists, Dietitians, Clinical Psychologists, etc.

RECRUITINGThe Pittsburgh Sleep Quality Index (PSQI)
The PSQI is a self-report measure of sleep quality among seven subscales including subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, sleep medication, and daytime dysfunction. The scale's validity and reliability has been determined among clinical and older adult populations. For reporting, seven component scores are derived, each scored 0 (no difficulty) to 3 (severe difficulty). The component scores are summed to produce a global score (min: 0 and max: 21). Higher scores indicate worse sleep quality. Time to completion is 5-10 minutes.
Time frame: Administered baseline, one week before surgery, and 45 days after surgery
Sleep self-efficacy scale
Self reported questionnaire measuring confidence in one's ability to change sleep behaviour. This scale contains 13 items scored 1-5 (min: 13, max: 65). Greater scores indicate more sleep self-efficacy.
Time frame: Baseline, 1 week presurgery, 45 days after surgery.
Sleep diary - Sleep duration
Self-reported by the participant in the sleep diary each day for 1 week.
Time frame: Baseline, presurgery, 45 days after surgery
Sleep diary - Sleep efficiency
Time in bed and sleep duration are self-reported by the participant in the sleep diary each day for 1 week. Sleep efficiency is calculated as sleep duration/time in bed and expressed as a percentage.
Time frame: Baseline, presurgery, 45 days after surgery
Sleep diary - Sleep latency
Self-reported by the participant in the sleep diary each day for 1 week.
Time frame: Baseline, presurgery, 45 days after surgery
Sleep diary - Sleep quality
Self-reported by the participant in the sleep diary each day for 1 week using a 5-pt Likert scale ranging from "Very poor" to "Very good" (scored 0-4). Higher scores indicate better quality sleep.
Time frame: Baseline, presurgery, 45 days after surgery
Wrist-worn actigraphy - Sleep duration
All participants will be provided with a Fitbit Inspire 3, a small non-intrusive and waterproof device that uses actigraphy to measure orientation and movement and uses photoplethysmography (PPG) to detect periodic changes in blood flow beneath the sensor; thereby measuring changes in heart rate. This device is worn like a wrist-watch. The activity tracker measures sleep-wake activity to measure sleep duration expressed in minutes.

PROMIS 29+2
The Patient-Reported Outcomes Measurement Information System (PROMIS) is a set of person-centred measures that evaluates physical, mental, and social health. The PROMIS 29+2 Profile v2.1 (PROPr) will be administered. The PROMIS instruments have been used and validated extensively in clinical There are 31 questions answered using a Likert scale from 1-5. Each domain (physical function, anxiety, depression, cognitive function, sleep disturbance, fatigue, social activity, and pain) has 2-4 items. Higher score is more of that concept. Raw scores are converted into T scores. The T-score rescales the raw score into a standardized T-score with a mean of 50 and a standard deviation (SD) of 10. Time to completion: 5-10 minutes
Time frame: Baseline, presurgery, 45 days after surgery
