Study summary

The purpose of this study is to determine whether the environmental simulation of daytime and night time alternation as well as by the nutrition protocol corresponding to the daily rhythm are beneficially affect the recovery of patients treated in the Intensive Care Unit (ICU) requiring mechanical ventilation.

Read the 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.

Study arms

  • 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.

    Other: Controlled light and noise · Other: Controlled nutrition

  • 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.

    Other: Controlled light and noise

  • 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.

Interventions

  • OtherControlled light and noise

    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.

    Also known as: Environmental simulation of the daytime and night time alternation

  • OtherControlled nutrition

    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.

    Also known as: Nutrition protocol that is in accordance with the daily rhythm

What researchers measure

Primary outcomes

  1. Change of the Multiple Organ Dysfunction Score value (delta MODS) from baseline to the end of the study treatment

    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.

    Time frame: Over the ICU treatment period but no more than 10 days

Secondary outcomes

  1. Change of the MODS value (delta MODS) between worst and last score during the study treatment

    Change of the MODS value between worst and last score over the ICU treatment period but no longer than 10 days.

    Time frame: Over the ICU treatment period but no more than 10 days

  2. Number of participants with gastric retention

    Number of participants with at least 250ml gastric retention at least one time

    Time frame: over the ICU treatment period but no more than 10 days

  3. Number of participants with delirium

    Number of participants with at least one evaluated Intensive Care Delirium Screening Checklist (ICDSC) score between 4-8

    Time frame: over the ICU treatment period but no more than 10 days

Other outcomes

  1. Change of the acute physiology and chronic health evaluation II (APACHE II) score from baseline to the end of the study treatment

    Time frame: during study participation but but no more than 10 days

  2. Change of the Sequential Organ Failure Assessment (SOFA) score from baseline to the end of the study treatment

    Time frame: during study participation but but no more than 10 days

  3. Change of the Simplified Acute Physiology II score (SAPS II) score from baseline to the end of the study treatment

    Time frame: during study participation but but no more than 10 days

  4. average daily dose of sedatives

    Time frame: during study participation but but no more than 10 days

  5. length of ICU treatment from admission to discharge in days

    Time frame: during study participation but no more than 99 days
