Sleep plays a key role in immune, metabolic, and neurological regulation, particularly in critically ill patients. However, the intensive care environment significantly disrupts sleep due to noise, light exposure, and frequent medical interventions, leading to circadian rhythm disturbances. Poor sleep in ICU patients is associated with increased morbidity, mortality, prolonged mechanical ventilation, and long-term psychological complications. Current studies report fragmented sleep with reduced deep sleep stages but are limited by short monitoring periods and small sample sizes. No study has yet assessed longitudinal sleep evolution throughout ICU stay. This study aims to characterize sleep dynamics from the acute phase to recovery using a simplified EEG device (Sleepscan®). Sleep will be recorded during the first three nights and the last night before ICU discharge. Environmental factors (noise, light) and clinical data will also be collected. This longitudinal intra-individual analysis will identify critical periods of sleep disruption. Results may guide future targeted interventions to improve sleep quality and patient outcomes in ICU.
308 studies on the registry are indexed under Sleep Deprivation; 62 are open to participants now.
This study's planned enrollment of 40 is close to the median of 44 across 253 interventional studies indexed under Sleep Deprivation.

Exclusion Criteria:
Adult ICU patients with expected stay ≥4 days undergoing repeated sleep monitoring using Sleepscan® device and actigraphy, without therapeutic intervention.
Other: Sleep monitoring using Sleepscan® · Other: Actigraphy
Non-invasive EEG-based sleep monitoring using the Sleepscan® device. Three scalp electrodes (frontal, mastoid, central) are applied with a headband for overnight recordings (12 hours, 8 PM-8 AM) during four nights (N1, N2, N3, and last night before discharge). Data are automatically analyzed and secondarily reviewed.
An actimeter placed on the ankle to measure motor activity and estimate sleep-wake cycles during the first 72 hours and the last 24 hours of ICU stay.
Median continuous sleep time
Median duration (in minutes) of continuous sleep episodes ≥10 minutes measured using EEG recordings via Sleepscan®
Time frame: Nights 1, 2, and 3 after ICU admission and the last night before ICU discharge, assessed up to 90 days after ICU admission.
Total sleep time
Median total sleep time (minutes) measured by EEG
Time frame: Nights 1, 2, and 3 after ICU admission and the last night before ICU discharge, assessed up to 90 days after ICU admission.
Deep sleep time
Median duration of deep sleep stages
Time frame: Nights 1, 2, and 3 after ICU admission and the last night before ICU discharge, assessed up to 90 days after ICU admission.
Micro-arousal index
Number of micro-arousals per hour
Time frame: Nights 1, 2, and 3 after ICU admission and the last night before ICU discharge, assessed up to 90 days after ICU admission.
ICU length of stay
Duration of ICU hospitalization (days)
Time frame: At ICU discharge (up to 90 days after ICU admission.)
SOFA score evolution
Organ failure assessment score at ICU admission and discharge
Time frame: At ICU admission and ICU discharge (up to 90 days after ICU admission.)
Sleep comparison (ventilated vs non-ventilated patients)
Median total sleep time comparison between groups
Time frame: Nights 1, 2, and 3 after ICU admission and the last night before ICU discharge, assessed up to 90 days after ICU admission.
Start is estimated for Dec 2026; primary completion for May 2027, 5 months later.
Of 142 non-industry interventional studies with no phase under Sleep Deprivation, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 9 and three quarters within 41. This study's planned 5 months is below that.
Counting every sponsor, half of 151 studies reached it within 17 months; a quarter within 8 and three quarters within 37.
