Effect of a Quality Improvement Project to Reduce Noise in a Pediatric Unit

A systematic review and proposed conceptual model of sleep disturbances during pediatric hospitalizations

STUDY OBJECTIVES

The current review aims to examine factors that influence pediatric inpatient sleep and determine the effectiveness of sleep promotion interventions among hospitalized children.

METHODS

A systematic literature search was conducted across PubMed, PsycINFO, CINAHL, Cochrane Central, Web of Science, Embase, and Scopus databases. Studies included children with a mean age between 1 and 18 years old that either described factors affecting the sleep of children who are hospitalized on a non-intensive care unit or reported on sleep-related intervention outcomes. We conducted separate narrative reviews for each of the two aims and then synthesized findings from quantitative and qualitative studies across both aims.

RESULTS

Forty-five articles were included for review. Despite most sleep disturbances being attributed to environmental disruptions (e.g. noise, staff interruptions), most interventions targeted the child level using relaxation techniques. Although the majority of interventions were small pilot studies, preliminary findings appear to positively impact sleep duration. The Pediatric Inpatient Sleep Model was proposed to illustrate connections between sleep disturbances, factors influencing sleep, and existing intervention components.

CONCLUSIONS

Replication studies are needed, including larger-scale sleep promotion interventions among hospitalized children. Given the identification of environmental factors as the main cause of night wakings, environmental modifications are crucial. Additional research examining contributors to intraindividual variability in disrupted sleep patterns during hospitalizations as well as the consequences of these disturbances is warranted.

Impact of Sleep Deprivation in the Neurological Intensive Care Unit: A Narrative Review

Sleep is fundamental for everyday functioning, yet it is often negatively impacted in critically ill patients by the intensive care setting. With a focus on the neurological intensive care unit (NeuroICU), this narrative review summarizes methods of measuring sleep and addresses common causes of sleep disturbance in the hospital including environmental, pharmacological, and patient-related factors. The effects of sleep deprivation on the cardiovascular, pulmonary, immune, endocrine, and neuropsychological systems are discussed, with a focus on short-term deprivation in critically ill populations. Where evidence is lacking in the literature, long-term sleep deprivation studies and the effects of sleep deprivation in healthy individuals are also referenced. Lastly, strategies for the promotion of sleep in the NeuroICU are presented.
