What this trial studies

This intervention focuses on optimizing the sleep environment for critically ill patients in the ICU to address significant disturbances in sleep and circadian rhythms. The study implements a multifaceted approach to control environmental factors such as light and noise, which are known to disrupt sleep. By monitoring and adjusting these factors, the goal is to enhance both the quantity and quality of sleep for patients undergoing invasive mechanical ventilation. The study aims to evaluate the impact of these interventions on patient outcomes, including delirium and overall recovery.

Who should consider this trial

Good fit: Ideal candidates for this study are critically ill patients who have been on invasive mechanical ventilation for at least 72 hours and are not heavily sedated.

Not a fit: Patients with pre-existing sleep disturbances or severe comorbidities that limit their life expectancy may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly improve sleep quality and overall recovery for critically ill patients in the ICU.

How similar studies have performed: While there have been limited studies on sleep optimization in the ICU, this multifaceted approach is relatively novel and has not been extensively tested.

Eligibility criteria

Inclusion Criteria:

* Patient under invasive mechanical ventilation for at least 72 hours.
* Patient without sedation or with superficial sedation level (SAS 3-4 by Sedation- Agitation Scale), during most of the daytime within the 24 previous hours

Exclusion Criteria:

* Patient who required mechanical ventilation in another episode of hospitalization in the 2 months before screening.
* Patients with primary neurological or neurosurgical disease.
* Presence of mental or intellectual disability prior to hospitalization or communication/language barriers.
