Clinical Trial Summary

In the WEsleep study, the investigators will perform a cluster randomized controlled trial. 3 surgical and 3 medical departments will be randomized to implement low-cost and simple interventions aimed at improving sleep in admitted patients. Another 3 surgical and 3 medical departments will be randomized to function as control groups. Subjective sleep quality and sleep-wake timing will be assessed in adult medical and surgical patients admitted into one of 12 participating wards, using questionnaires and a sleep diary. In addition, in a subset of participants, objective sleep measures will be assessed in with an EEG headband and a sleep mat.


Description:

Objectives Primary objective Our primary objective is to investigate whether a set of low-cost and easily applicable interventions improves subjective sleep quality of hospitalized patients on the second night of admission (for medical patients) and first postoperative night (for surgical patients) as measured the Richards-Campbell sleep questionnaire, comparing between intervention and control departments. Secondary objectives - To investigate whether the WEsleep interventions improves subjective sleep quality for all night of admission (max. 7) - To investigate whether the WEsleep interventions reduced the lowering of subjective sleep quality during admission when compared to subjective sleep quality before admission (on a work-free day 30 days before admission, retrospectively assessed at inclusion) - To investigate whether the disruption of the circadian timing system (as measured by the diurnal phase shift of midpoint of sleep) was smaller for patients in the intervention group on the first postoperative night for surgical patients and the second night of admission for medical patients - To investigate whether the WEsleep interventions reduced night-to-night changes in subjective sleep-wake timing (i.e. midpoint of sleep, on- and offset, duration, latency, inertia and daytime napping) for all nights of admission (max. 7) - To investigate the association between the timing of food intake (i.e. first and last meal of the day and whether food was eaten after 21:00h) and sleep quality and timing. - To investigate the association between quality of recovery and sleep quality and sleep-wake timing - To investigate 30-day mortality for patients admitted into intervention and control departments - To investigate 30-day incidence of delirium for patients admitted into intervention and control departments - For surgical patients: to investigate the 30-day incidence of surgical site infections - Objective sleep substudy: to investigate the difference between intervention and control departments in objective sleep efficiency of hospitalized patients on the second night of admission (in medical patients) and the first postoperative night on ward (in surgical patients) as measured by the Dreem-3 EEG-headband - Objective sleep substudy: to investigate whether the WEsleep interventions reduced night-to-night changes in objective sleep-wake timing (i.e. midpoint of sleep, on- and offset, duration, latency, inertia and daytime napping) for all nights of admission (max. 7) - Objective sleep substudy: to investigate whether the WEsleep interventions influence night-to-night changes in objective sleep measures (as measured by the Dreem 3 EEG-headband and Withings Sleep analyzer) for all nights of admission (max. 7) - Objective sleep substudy: to investigate the difference between objective sleep measures (as measured by Dreem-3 EEG-headband and Withings Sleep Analyzer) and subjective sleep measures (as measured by the Richard Campbell Sleep Questionnaire and the Consensus Sleep Diary) for a population of hospitalized medical and surgical patients - Objective sleep substudy: to investigate the association between quality of recovery and objective sleep quality and sleep-wake timing - Objective sleep substudy: to investigate the association between 30-day mortality and objective sleep quality and quantity - Objective sleep substudy: to investigate the association between 30-day incidence of delirium and objective sleep quality and quantity - Objective sleep substudy: to investigate the association between the 30-day incidence of surgical site infections and objective sleep quality and quantity (for surgical patients) Study Procedure: 6 departments will be randomized (3 surgical, 3 medical) to receive the WEsleep-interventions, which will consist of: 1) Postponing morning nursing rounds to avoid waking patients early and daily assessment of sleep quality by the nurse during morning rounds; 2) Implementing sleep promoting interventions, including optimization of medication and iv fluid timing; 3) Education for health care professionals on sleep; 4) Implementing sleep rounds and change department infrastructure; including 'sleep menu' where patients can choose from earplugs, eye masks, and warm socks. Implement blackout curtains depending on baseline light intensity. Implementation of the interventions will be evaluated on a regular basis throughout the length of the study to make sure that all interventions are provided to our patients as planned. Before implementation, a baseline measurement will be conducted on all participating departments in a small number of patients (which is not part of the sample size). After study onset, we observed that some interventions were gradually implemented. As such, we decided that for optimal assessment of the effect of the intervention a run-in period of 12 weeks before starting assessment of the primary and secondary outcomes would be reasonable. Sleep measurements between study onset and outcome will be used to guide implementation and will be reported in eventual journal articles. After 12 weeks (that is, after July 1st), 33 patients per participating department will be included, for a total of 396 patients (12 departments with 33 patients each) and analyzed for the outcomes of the study. Informed consent for sleep measurements will be obtained on the first or second day of admission into one of the participating wards. Patients will be followed until discharge or for a maximum of 7 nights of admission. Patient characteristics, as well as data on the admission will be extracted from the electronic medical record. In the objective sleep substudy, 24 patients will be recruited from each group (medical intervention and control groups, surgical intervention and control groups), for a total of 96 patients. Measurements between April 11th and June 30th will be used to guide implementation of interventionsPatients included after July 1st will be analyzed for the outcomes of the substudy. Informed consent for the substudy will be obtained separately at the same time as consent for the main study. All patients participating in the main study will be asked to participate in the substudy as well. After obtaining consent, a lottery system will decide which patients can participate in the substudy (due to the scarcity of available Dreem-3 EEG headbands and Withings Sleep Analyzers). Patients will be asked to complete two questionnaires daily: Richards Campbell Sleep Questionnaire (RCSQ) on subjective sleep quality Consensus Sleep Diary (CSD) for day-to-day sleep wake timing during admission Furthermore, patients are asked at admission to complete the two questionnaires on sleep quality and sleep-wake timing on work- and work-free days (RCSQ and CSD) retrospectively, i.e. for 30 days before admission. Patients will also complete a Quality of Recovery 15 (QoR-15) questionnaire twice (once at one day after surgery/first day of admission and once three days after surgery/third day of admission). In the substudy, objective sleep in patients will be measured with the Dreem-3 EEG-headband and the Withings Sleep Analyzer. The Dreem-3 headband uses electro-encephalography (EEG) and a validated algorithm to differentiate between wakefulness and various sleep stages (Rapid-Eye Movement (REM)-sleep and non-REM N1, N2 and N3 sleep) and the time at which these occur. The Withings Sleep Analyzer can be placed under the mattress and uses measurement of movement to differentiate between wakefulness and light, deep and REM-sleep and the times at which these occur.

Outcome

Type Measure Description Time frame Safety issue
Primary Subjective Sleep Quality during admission Subjective sleep quality will be assessed with the Richard Campbell Sleep Questionnaire (RCSQ). The RCSQ measures sleep quality on five questions using a visual analogue scale (VAS), ranging from 0 to 100, with higher scores indicating a better sleep quality.
A sixth question was added to assess noise levels (as is quite customary), using a VAS-scale, ranging from 0-100, with a higher score indicating more noise
Second night of admission (for medical patients), first postoperative night on ward (for surgical patients)
Secondary Night-to night changes in subjective sleep quality Subjective sleep quality will be assessed with the Richard Campbell Sleep Questionnaire (RCSQ). The RCSQ measures sleep quality on five questions using a visual analogue scale (VAS), ranging from 0 to 100, with higher scores indicating a better sleep quality.
A sixth question was added to assess noise levels (as is quite customary), using a VAS-scale, ranging from 0-100, with a higher score indicating more noise
The first night until the seventh night of admission; if the patient is discharged before 7 nights of admission, all nights of admission will be analyzed
Secondary Difference in subjective sleep quality between during admission and at home Subjective sleep quality will be assessed with the Richard Campbell Sleep Questionnaire, with five questions on a visual analogue scale, ranging from 0 to 100, with higher scores indicating better sleep quality. For this outcome, we will assess the subjective sleep quality at home retrospectively at inclusion. Second night of admission vs. a work- and workfree day 30 days before admission
Secondary Diurnal phase shift of sleep-wake timing The phase shift of sleep-wake timing will be assessed by comparing midpoint of sleep during admission with midpoint of sleep on a work-free day before admission, both measured with the Consensus Sleep Diary (CSD). For this outcome, we will assess sleep-wake timing at home retrospectively at inclusion. Second night of admission (for medical patients) or first postoperative night (for surgical patients) vs. a workfree day 30 days before admission
Secondary Night-to-night changes in sleep-wake timing The changes in sleep-wake timing (i.e. midpoint of sleep, sleep on- and offset time, sleep duration, sleep latency & inertia and daytime napping), as measured by the CSD. The first night until the seventh night of admission; if the patient is discharged before 7 nights of admission, all nights of admission will be analyzed
Secondary Timing of food intake and sleep quality/timing The association between food intake timing (i.e. first and last meal of the day and whether food was eaten after 21:00h), as measured by asking patients directly for the time of the first and last meal of the day and whether patients ate after 21:00h), and subjective sleep quality and sleep-wake timing (as measured by the Richard Campbell Sleep Questionnaire (with five questions on a visual analogue scale ranging from 0-100 with higher scores indicating better sleep quality) and Consensus Sleep Diary (with questions on sleep-wake timing) respectively). The first night until the seventh night of admission; if the patient is discharged before 7 nights of admission, all nights of admission will be analyzed
Secondary Quality of recovery (for surgical patients) and sleep quality/timing The association between quality of recovery (in surgical patients), as measured by the Quality-of-Recovery 15 item questionnaire (QoR-15), and subjective sleep quality and sleep-wake timing (as measured by the Richard Campbell Sleep Questionnaire and Consensus Sleep Diary respectively). The QoR-15 will be completed twice by patients. First and third day after surgery
Secondary 30 day mortality 30-day mortality, assessed by checking the medical record retrospectively 30 days after admission. 30 days after admission
Secondary 30-day incidence of delirium during admission 30-day incidence of the clinical diagnosis of delirium during hospitalization, as assessed by a physician during admission. Patients will be assessed for delirium at the request of nursing staff or if the score of the Delirium Observation Screening scale is 3 or higher. The Delirium Observation Screening scale ranges from 0 to 39, with higher scores indicating a higher chance of delirium. 30 days after admission
Secondary 30-day incidence of surgical site infections (for surgical patients) 30-day incidence of surgical site infections, as assessed by physicians from the department where patient is admitted during hospitalization. If the patient obtained a surgical site infection after discharge, incidence was assessed in the outpatient clinic by a physician from the department where patient was admitted. 30 days after admission
Secondary Objective sleep substudy: Sleep efficiency (objectively measured) during admission Objective sleep quality will be measured by the Dreem-3 headband, using electro-encephalography (EEG) to differentiate between wakefulness, Rapid-Eye-Movement (REM) sleep and non-REM N1, N2 and N3 sleep. The primary outcome measure will be sleep efficiency (time slept divided by time in bed spent trying to sleep), compared for patients on intervention and control departments. Second night of admission (medical patients) and first postoperative night on surgical ward (for surgical patients)
Secondary Objective sleep substudy: Differences in objective sleep measures of sleep-wake timing during admission Sleep-wake timing will be assessed by the Dreem-3 headband, using electro-encephalography (EEG) to differentiate between wakefulness, Rapid-Eye-Movement (REM) sleep and non-REM N1, N2 and N3 sleep, and the Withings Sleep Analyzer, differentiating between wakefulness, REM- and light and deep sleep. Changes in sleep-wake timing (i.e. midpoint of sleep, sleep on- and offset time, sleep duration, sleep latency & inertia) will be compared for patients on intervention and control departments.
