Critically ill children demonstrated disrupted sleep health, with irregular PICU sleep behaviors, frequent sedation, little daytime activity consolidation, and short fragmented sleep episodes that rarely matched baseline sleep patterns.
A substantial proportion of critically ill children had atypical baseline sleep health prior to PICU admission.
Children in the PICU spent a significant portion of their time sedated.
Total sleep time in the PICU rarely matched participants' baseline sleep duration.
Critically ill children demonstrated little daytime activity consolidation and experienced short, fragmented sleep episodes in the PICU.
There were few associations between baseline sleep health and PICU sleep health.
Implementation of the nurse-led chronotherapeutic care bundle (R2 bundle) showed few associations with PICU sleep health outcomes.
Nearly half of critically ill children with acute respiratory failure had atypical sleep health even before their PICU admission.
This research suggests that children admitted to the pediatric intensive care unit (PICU) with serious breathing problems experience severely disrupted sleep. The study looked at 52 children between 6 months and 17 years old and found that their sleep in the hospital almost never matched their normal sleep patterns from home — in fact, their total sleep time was within one hour of their usual amount on only 11% of hospital days. Children also spent at least a quarter of their hospital days heavily sedated, had very little normal daytime activity, and their sleep came in short, broken-up episodes rather than consolidated rest. Notably, nearly half of the children (45%) already had unusual or problematic sleep patterns before they were even hospitalized, suggesting pre-existing sleep challenges in this population. The study also tested whether a special nursing care program designed to support healthy sleep timing (the 'chronotherapeutic care bundle') made a difference, but found little evidence that it significantly changed children's sleep patterns in the PICU. This may reflect how difficult it is to improve sleep in an environment filled with medical equipment, frequent check-ins, bright lights, and the use of sedating medications. This research matters because poor sleep in children can interfere with healing, brain development, and recovery from illness. By carefully documenting just how disrupted sleep is in critically ill children — and that many already had sleep problems before admission — this study provides a foundation for developing better, more targeted nursing strategies to improve sleep for children in intensive care settings.
