Overnight noise levels in the medical ICU could potentially lead to worse outcomes, states research.

Results showed significant in-room activity (ie, vital sign recording) and sound level maximums that exceeded 83 dB(C) every hour between midnight and 4:00 AM in every room monitored, which exceeds the sound levels recommended by WHO.
Researchers conclude that sleep disruption in the MICU is prevalent and may be linked to delirium and immune dysfunction, as well as potentially worse outcomes due to patient sleep deprivation. This study was presented during CHEST 2012, the annual meeting of the American College of Chest Physicians, held October 20 – 25, in Atlanta, Georgia.
