BACKGROUND: Sleep-wake disturbances are underevaluated among children with acquired brain injury surviving critical care. We aimed to quantify severity, phenotypes, and risk factors for sleep-wake disturbances.
METHODS: We performed a prospective cohort study of 78 children aged ≥3 years with acquired brain injury within three months of critical care hospitalization. Diagnoses included traumatic brain injury (n = 40), stroke (n = 11), infectious or inflammatory disease (n = 10), hypoxic-ischemic injury (n = 9), and other (n = 8). Sleep Disturbances Scale for Children standardized T scores measured sleep-wake disturbances. Overall sleep-wake disturbances were dichotomized as any total or subscale T score ≥60. Any T score ≥70 defined severe sleep-wake disturbances. Subscale T scores ≥60 identified sleep-wake disturbance phenotypes.
RESULTS: Sleep-wake disturbances were identified in 44 (56%) children and were classified as severe in 36 (46%). Sleep-wake disturbances affected ≥33% of patients within each diagnosis and were not associated with severity of illness measures. The most common phenotype was disturbance in initiation and maintenance of sleep (47%), although 68% had multiple concurrent sleep-wake disturbance phenotypes. One third of all patients had preadmission chronic conditions, and this increased risk for sleep-wake disturbances overall (43% vs 21%, P = 0.04) and in the traumatic brain injury subgroup (52% vs 5%, P = 0.001).
CONCLUSIONS: Over half of children surviving critical care with acquired brain injury have sleep-wake disturbances. Most of these children have severe sleep-wake disturbances independent of severity of illness measures. Many sleep-wake disturbances phenotypes were identified, but most children had disturbance in initiation and maintenance of sleep. Our study underscores the importance of evaluating sleep-wake disturbances after acquired brain injury.
