Brief Summary

Sleep disturbances are common among intensive care unit (ICU) patients and have been associated with difficult weaning from invasive mechanical ventilation, with an increased risk of endotracheal intubation. Other studies have reported associations between sleep disturbances and prolonged ICU length of stay or the occurrence of delirium. Among the factors contributing to sleep impairment, nighttime care interventions have been identified as a major cause. The management of sleep disorders in the ICU remains complex and often disappointing, and no pharmacological treatment is currently formally recommended. Very recently, a considerable improvement of sleep quantity (+50%) and quality (doubling of deep sleep quantity) has been reported by reorganizing nighttime nursing care according to patients' sleep cycles, using a sleep monitoring medical device. The objective of this study is to quantify the impact of a better sleep on prognosis. Sleep will be improved using sleep-guided nursing care during nighttime thanks to a real-time sleep monitor (Sleepscan°). The primary endpoint is the proportion of patients requiring invasive mechanical ventilation or who have died at day 7 after inclusion. The main secondary outcomes include the duration of ICU stay, the number of delirium free-days, the score at a discomfort scale, the score at a post-traumatic stress disorder scale at ICU discharge. Intensive care unit-related costs will be assessed. A multi-sites, prospective, randomized, open-label, superiority trial with two parallel arms will be conducted. Awake and conscious patients without continuous sedation, regardless of ventilatory support, with no indication for urgent intubation (\<12 hours) and with an expected ICU length of stay greater than 48 hours will be included. The intervention will consist of sleep-guided nighttime nursing care using the Sleepscan monitor from 7:00 p.m. to 7:00 a.m., every night until ICU discharge or day 7. Sleep-guided nursing care consist in postponing non urgent care (such as temperature measurement…) and avoiding entering the room when patients are asleep. Otherwise, when patients are awake, instructions are to go for all care, to cluster and anticipate nursing care and perform comfort care. In the control group, sleep will also be recorded using the same device but the tablet will not display the patient's sleep (or awake) status, and nighttime nursing care will be performed according to usual practice and independently of patients' sleep cycles. Based on our preliminary data and previous studies, it has been estimated that 230 patients per group will be required to detect a reduction in the proportion of patients intubated or deceased at day 7 from 20% in the control group to 10% in the intervention group. The intention-to-treat analysis population will include all randomized patients. Demonstrating an improvement in patient prognosis through enhanced sleep quality would represent a major advancement for intensive care medicine. Reducing the need for invasive mechanical ventilation may lead to shorter ICU stays, lower mortality, fewer post-ICU complications, and reduced hospital costs.

Study Arms (2)

Control arm

ACTIVE COMPARATOR

Standard care with sleep recording using the Sleepscan® device.

Device: Sleepscan device

Experimental arm

EXPERIMENTAL

Sleep-guided nursing carewith sleep monitoring using the Sleepscan® device.

Device: Sleepscan device; Procedure: Sleep-guided nursing care

Interventions

Sleepscan device DEVICE

The Sleepscan® will be installed around 8:00 p.m., for both groups. For the control group, the tablet will not display the sleep/wake status. For the experimental group, the tablet will display the sleep/wake status.

Control arm; Experimental arm

Sleep-guided nursing care PROCEDURE

Nighttime nursing care will be guided by the Sleepscan device whether the patient is awake or asleep. When "Prioritize Sleep" signal will be displayed, caregivers may choose to postpone non-urgent care and reduce signal light and sound levels. When "Prioritize Care" signal will be displayed, caregivers prioritize care will be encouraged.
