Clinical Trial Summary

The investigators will examine the effects of dynamic light therapy on circadian rhythms in intensive care unit (ICU) patients. In a randomized controlled trial (RCT), they will investigate the effects of a specific light algorithm on rhythms of serum melatonin, clock gene expression, the proteome, and metabolome, compared to standard hospital lighting, supported by the data science algorithms to improve vital-based algorithms with light interventions.

Secondary Level of analgesia 1 Severity of pain will be measured with the Numeric Rating Scale (NRS). A higher score corresponds to a higher severity of pain.Score values from 0 to 10. A higher score means worse outcome. Participants will be followed up until discharge from the intensive care unit (maximum up to day 5)
Secondary Level of analgesia 2 Severity of pain will be measured with the Visualized Numeric Rating Scale (NRS-V). A higher score corresponds to a higher severity of pain.Score values from 0 to 10. A higher score means worse outcome. Participants will be followed up until discharge from the intensive care unit (maximum up to day 5)
Secondary Level of analgesia 3 Severity of pain will be measured with the Faces Pain Scale-Revised (FPS-R). A higher score corresponds to a higher severity of pain.Score values from 0 to 10. A higher score means worse outcome. Participants will be followed up until discharge from the intensive care unit (maximum up to day 5)
Secondary Level of analgesia 4 Severity of pain will be measured with the Behavioral Pain Scale (BPS) . A higher score corresponds to a higher severity of pain.Score values from 3 to 12. A higher score means worse outcome. Participants will be followed up until discharge from the intensive care unit (maximum up to day 5)
Secondary Level of analgesia 5 Severity of pain will be measured with the Behavioral Pain Scale for Non- Intubated (BPS-NI). A higher score corresponds to a higher severity of pain. A higher score corresponds to a higher severity of pain.Score values from 3 to 12. A higher score means worse outcome. Participants will be followed up until discharge from the intensive care unit (maximum up to day 5)
Secondary Total amount of opioids Total amount of opioids administered per ICU treatment day will be measured in with morphine equivalents for each administered opioids. Participants will be followed up until discharge from the intensive care unit (maximum up to day 5)
Secondary Total amount of sedatives Total amount of sedatives administered per ICU treatment day by dose summation for each sedative. Participants will be followed up until discharge from the intensive care unit (maximum up to day 5)
