PMID 37591147WHAT IT FOUND
In ten critically ill children, those with delirium had more frequent awakenings and shorter sleep episodes than those without.
Higher clinician caregiving frequency was also associated with worse sleep and delirium. This pilot links bedside care patterns to sleep disruption.
Key findings
01Children with delirium experienced more awakenings per sleep hour and shorter sleep episodes than children without delirium.
02Increased clinician caregiving frequency and duration were associated with worse sleep measures and higher delirium prevalence.
03Light levels were generally low, while sound levels frequently exceeded recommended thresholds, but neither was strongly associated with sleep or delirium in this small sample.

What it does not show
The sample size was very small (10 children), limiting the ability to detect true associations or generalize findings. The study was a pilot, so it cannot determine causality between caregiving patterns, sleep, and delirium. Participants had low severity of illness and short stays, so results may not apply to sicker children. Video coding missed some overnight data due to poor visibility. No statistical corrections were made for multiple comparisons.

The easy way to misread this
Do not assume that reducing caregiving frequency will prevent delirium. This is a small pilot study showing associations, not a randomized trial proving that changing care patterns improves outcomes.
