Outcome Measures

Primary Outcomes (4)

  • Changes of the circadian rhythm during admission by actigraphy

    Actigraphy data

    an average of 2 weeks of continuous monitoring since baseline till discharge, up to 4 weeks

  • Changes of the circadian rhythm during admission by heart-rate-variation-analysis

    heart-rate-variation-analysis data

    baseline for 48hours, and 24hours before discharge

  • Changes of Melatonin level

    Melatonin level

    collect saliva in the morning and at the night of Day 1 and the day of discharge

  • Changes of Vitamin D level

    Vitamin D level

    blood sampling at Day 1 and the day of discharge

Secondary Outcomes (2)

  • Confusion Assessment Method for the Intensive Care Unit

    evaluate daily since baseline to discharge, for an average of 2 weeks, up to 4 weeks

  • Intensive Care Delirium Screen Checklist

    evaluate daily since baseline to discharge, for an average of 2 weeks, up to 4 weeks
