Detailed Description
The homeostasis of human body is significantly disturbed when organs' work-relax periods are not harmonized. Intensive Care Unit (ICU) patient's circadian rhythm is almost inevitably upset as a result of their disease and/or medical intervention. There are numerous animal studies prove that circadian rhythm and periodic dynamics are directly related to healing time and hence, mortality rate. Although, one of the main messengers of circadian synchronization is melatonin, it is overridden by temperature, and a number of other factors from e.g. the digestive tract. If the circadian rhythm is disturbed, the function of different organ systems becomes desynchronized and chaotic.
ICU environment and patient-care activities brings major drawbacks as well mainly by necessary presence of noise and light. It has been shown that ICU settings have an impact on patients' sleep, which can easily lead to delirium and circadian disruption. There are significant data showing strong correlation between delirium and ICU length of stay/ mortality.
The focus of this study is the environmental modulation at the ICU with controlled light, noise and nutrition conditions. Controlled light conditions are created with artificial light during daytime and sleeping mask during night time. Earplugs are used during night time for controlled noise conditions. Nutrition is carried out only during daytime both in case of enteral and parenteral feeding.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Controlled light, noise and nutrition
Simultaneously with the standard treatment performed at the clinical trial site environmental simulation of night time and daytime alternation as well as the nutrition protocol corresponding to the daily rhythm will be applied.
|
Purpose: The day-night ratio of the environmental illumination (limit 8 lux) and that of the noise level (limit 20 dBA) must correspond to the necessary value required by a healthy human body as defined by the National Sleep Foundation (USA). Implementation: Simulation of the daytime period is performed with blue predominant artificial light with colour temperature between 5500 and 8000 K with lux values of 1000-1200 measured at the head of the patient. Simulation of the nighttime period is performed with a sleeping mask and earplugs.
Other Names:
In compliance with the standard daily nutrition protocol, nutrition is carried out only during daytime both in case of enteral and parenteral feeding in accordance with European Society for Clinical Nutrition and Metabolism 2016 guidelines. Nutritional regimen should be stopped for 8 hours/24 at night (non-nutritional period may be depending on the work schedule of the actual ICU) , even if the daily energy/protein target is not reached.
Other Names:

Experimental: Controlled light and noise
Simultaneously with the standard treatment performed at the clinical trial site environmental simulation of night time and daytime alternation as well as the continuous nutrition (in accordance with the clinical trial site's standard practice) will be applied.

No Intervention: Control
The treatment of the study subject will be performed based on the clinical trial site's standard practice without environmental simulation or changes in the nutrition protocol.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change of the Multiple Organ Dysfunction Score value (delta MODS) from baseline to the end of the study treatment
Time Frame: Over the ICU treatment period but no more than 10 days
|
The primary efficacy endpoint is the change in MODS scale from baseline to the end of the study treatment period, i.e. deltaMODS.
Since the length of ICU stay may be different for subjects, the MODS rate of change per day (deltaMODS/day) will be the primary measure to characterize the treatment effect.

Over the ICU treatment period but no more than 10 days
